The present invention is directed to a probiotic method and composition for maintaining a healthy vaginal microbiome.
The vaginal microbiome is a dynamic, sensitive microenvironment that changes in response to pregnancy, the menstrual cycle, contraceptive use, and diet. A normal, healthy vaginal microbiota is dominated by a variety of Lactobacillus spp., including L. crispatus, L. gasseri, L. iners and L. jensenii. Vaginal dysbiosis predisposes women to a variety of adverse vaginal health conditions. The practice of vaginal douching, once believed to offer benefits, has recently been shown to cause vaginal dysbiosis that detracts, rather than improves upon, a woman's vaginal health.
Feminine hygiene products such as douches, wipes, sprays, washes, and powders are part of a fast-growing industry worth USD 2 billion in the US. Most of these products are marketed to women with the idea that women's bodies are problematic, unclean, and require cosmetic products to maintain a healthy state. Research now suggests that the use of feminine hygiene products may result in the development of more significant or additional symptoms resulting from increased washing and the associated disturbance of the normal vaginal microbiome. A Lactobacillus-depleted microbiome has been linked to a variety of adverse vaginal health outcomes, including preterm birth, bacterial vaginosis, and increased risk of sexually transmitted infections.
There is a long felt but unsolved need for a probiotic method and composition for maintaining a healthy vaginal microbiome. The vaginal microbiome is an intricate and dynamic microecosystem that constantly undergoes fluctuations throughout a woman's entire life. As further described herein, both methods and compositions are set forth to achieve the objective of maintaining a healthy vaginal microbiome at these various stages of a woman's life.
As set forth herein, various embodiments of the present invention are directed to ways to modulate the microbiome of women at various stages of their lives in order to enhance the health of their vaginas, as well as their overall health.
The vaginal microbiome is an intricate and dynamic micro-ecosystem that is a critical component of women's sexual, reproductive, and holistic health. However, in the United States, symptomatic vaginal complaints are responsible for more than 10 million office visits annually. Microbial dysbiosis and fungal infections are a primary cause of vaginitis, defined as inflammation or infection of the vagina. These conditions can cause significant discomfort and reduced quality of life, while also increasing the risk of sexually transmitted infections and adverse pregnancy outcomes. The current standard of care for the three main causes of vaginitis, bacterial vaginosis (BV), Candida infections, and trichomoniasis, is treatment with antibiotic or antifungal medications, which often result in high recurrence rates as they do not address the root cause: a disrupted vaginal microbiome.
Urinary tract infections (UTIs) are the most common bacterial infection in the general population, impacting over half of women in their lifetime and resulting in healthcare costs upwards of $2.8 billion annually. After an initial UTI, approximately 20%-30% of women will have a second UTI within 6 months. Recurrent UTIs (rUTIs; defined as 2 infections in 6 months or 3 infections in 1 year) significantly impact both a patient's health and the healthcare system and are often treated with long-term repetitive courses of antibiotics. A more effective approach to these recurrent UTIs is needed.
The age and hormone levels of women has a significant impact on the composition of the vaginal microbiome. Until puberty, estrogen levels remain low, which causes the vagina to be dominated with anaerobic micro-organisms. From puberty on, estrogen levels rise, leading to production of cervicovaginal secretions and colonization by high numbers of lactobacilli, with increasing concentrations of lactate as a result. Throughout the menstrual cycle estrogen and glycogen levels vary, ranging from low levels during menses to the highest levels before ovulation, effecting microbiome composition. Upon pregnancy, the vagina remains dominated by lactobacilli but is characterized by lower richness and diversity than in non-pregnant women. In menopause, estrogen and glycogen levels decrease, causing the prior Lactobacillus dominance to decrease and eventually cease.
A properly balanced vaginal microbiota prevents urogenital disorders like bacterial vaginosis (BV), urinary tract infections (UTIs), and yeast infections. Described herein are various probiotic compositions for maintaining a healthy vaginal microbiome that employ combinations of bacteria selected to reduce the number of pathogenic bacteria in the vagina and to achieve a healthy balance of beneficial bacteria, often involving the maintenance of a desired pH range to accomplish such an objective. Aspects of the present invention are directed to the provision of suitable pre-biotics, probiotics and post biotics in the distinct microbiomes of an individual is employed to arrive at a more comprehensive and holistic way to address dysbiosis of one or more of such microbiomes. Moreover, the dynamic environment of the vaginal microbiome is taken into consideration due to the dramatic events that occasion a woman's life, from the earliest stages of an infant, through childhood, puberty, adulthood, motherhood and finally as a woman enters late age. Each stage of life presents unique challenges with respect to maintaining healthful conditions for a woman, as well as for her infants that she birthed.
Thus, beginning with the profound impacts of the vaginal microbiome on the future health of an infant, certain aspects of the present invention are focused on compositions and methods directed to interventions for a pregnant mother to take with respect to an alteration of one of: her gut microbiome; and vaginal microbiome to positively affect the immunity for her child, with the objective to protect the child against future allergies. It is believed that the infant gut microbiota and immune system are primed shortly after birth with a direct connection to the maternal transfer of humoral immunity to the infant. Enhancing the bacterial population to which an infant is exposed with certain bacteria, for example certain isolated and/or combinations of strains of Escherichia, Staphylococcus, Bifidobacterium and/or Lactobacillus bacteria, is believed to protect an infant against later life allergies. Various embodiments of the present invention are directed to facilitating an infant's contact with select strains of bacteria, some for the infant's skin microbiome and others for the infant's gut microbiome, where in some embodiments, such bacterial strains are first provided on a mother's vagina so as to make such infant contact occur at the time of the infant's birth. As described herein, other forms of administration can also be employed, e.g. wipes provided with specific bacterial compositions, prebiotics, post-biotics, etc. such that an infant's skin is wiped with the same to confer colonization with beneficial bacteria.
There are different theories with respect to how an infant's microbiome is initially colonized, however, it appears that initial colonization largely occurs during vaginal or C-section birth, while acknowledging the importance of breastmilk, skin and feces bacteria transferred by a mother to her infant. In various embodiments of the present invention, infants are provided with bacteria to initiate or enhance the infant's colonization with Escherichia, Staphylococcus, Bifidobacterium and/or Lactobacillus, which preferably leads to a transition of the infant's gut microbiome to being dominated by Bifidobacterium microbiota due to milk consumption, and which shifts toward an adult-like microbiota when solid food is then introduced.
A decrease in Veillonella and/or Lachnospira bacteria is believed to reduce the risk of developing infantile asthma, wheezing and allergies. As such, certain embodiments of the present invention are directed to reducing these bacteria in a woman's vagina during the last stages of pregnancy so as to limit contact by such bacteria with a newborn infant. As described herein, there are various methods that may be employed to achieve such bacterial reduction without adversely affecting the survival of beneficial bacteria in a woman's vagina.
Certain other embodiments of the present invention are directed to the benefits to be derived from an increase in small chain fatty acid (SCFA) production by bacteria in a female's gut microbiome, while decreasing SCFA production in the individual's vaginal microbiome. While not bound by theory, the benefits provided by the bacterial production of various SCFAs, and in particular butyrate, such as via maintaining a population of F. prausniitzi in an individual's gut, are widely acknowledged as significant. Thus, many would mistakenly believe that in view of such health advantages, it would similarly be desirable to increase the production of SCFAs in other microbiomes, such as the vaginal microbiome. Aspects of the present invention, however, involve the modification of an individual woman's gut and vaginal microbiomes to increase SCFA production in the former and reduce it in the later.
The average healthy pH of the vagina is around 4±0.5. The low pH of the human vagina is quite unique as compared to other mammals, in which the vaginal pH ranges from 5.4 to 7.8. The main reason for this high acidity in humans is likely the dominance of lactobacilli. More than 70% of the bacteria in the human vagina are lactobacilli, while in other mammals this only accounts for 1%. In humans, the vaginal pH inversely correlates with the amount of lactate present. It is thus of importance in various embodiments of the present invention to adjust and maintain the pH of the vagina to be sufficiently acidic to allow lactic acid to exist and exert its protective qualities. During periods of bacterial vaginosis, the pH of the vagina typically increases, as well as the levels of some SCFAs.
The immunomodulatory roles of microbiota-generated SCFAs are different in the gut and vagina. SCFAs produced in the gut promote health, e.g. a rise in Lactobacillus and low pH, homeostasis, etc. In contrast, an increase SCFAs in the female reproductive system leads to a decrease in the Lactobacilli population and lactic acid concentration, which increases vaginal pH. Overall, an increase of SCFAs in the female reproductive system leads to mixed anaerobic populations and induces inflammation. These mixed anaerobic populations include Streptococcus, Bacteroides, Gardnerella Prevotella, Mycoplasma, Ureaplasma, Finegoldia, Mobiluncus, Leptotrichia, Eggerthella, Veillonella, Dialister, Atopobium, Megasphaera, Sneathia, Clostridiales BVAB 1-3, etc., that are seen in female genital tract diseases, such as BV and vulvovaginal candidiasis.
Anaerobes associated with BV can produce SCFAs in the women reproductive system through the fermentation of carbohydrates and amino acid catabolism. SCFAs in the female genital tract include propionate, acetate, isovalerate, isobutyrate, and n-butyrate. Collectively, SCFAs can lead to proinflammatory and dysbiotic effects in the female reproductive system.
Aspects of various embodiments of the present invention involve the purposeful generation of SCFAs in an individual's gut by the provision of certain butyrate producing bacteria, while at the same time, reducing the generation of SCFAs in the individual's vaginal microbiome. Thus, in certain embodiments of the present invention, with respect to a woman's vaginal microbiome, the population of specific bacteria is enhanced, such bacteria selected from the group consisting of L. crispatus, L. jensenii, and L. vaginalis, while the number of specific bacteria in the vaginal microbiome, including C. albicans and Gardnerella vaginalis, which are often encountered in vaginal infections, are reduced. The reduction of the latter bacteria may be achieved in various ways, e.g. via the employment of bacteriophages, antibiotics and/or the preferred use of CRISPR systems as elsewhere described herein, thereby selectively reducing the numbers of such undesired bacteria without killing the beneficial bacterial residing in the vagina.
In various embodiments of the present invention, and in recognition that a woman's body has various microbiomes that possess different characteristics, but which collectively define many health issues for each individual, aspects of the present invention include addressing more than one of a person's microbiome at the same time. For example, a woman may benefit from the modulation of her gut microbiome, as well as her oral microbiome, skin microbiome and vaginal microbiome. Instead of merely focusing on a single microbiome of an individual, various embodiments of the present invention are directed to addressing concerns that exist with at least two, and preferably at least three of the above-mentioned microbiomes of an individual—at approximately the same time. Perhaps surprisingly, certain beneficial attributes of one microbiome are not the same, and in some situations, are contrary to, the beneficial attributes of another microbiome from the same individual. For example, while it is increasingly viewed as a positive attribute for an individual's gut microbiome to possess bacteria that generate SCFAs, and in particular butyrate, this is not the case with respect to the vaginal microbiome of a woman, where an increase in production of SCFAs leads to an undesired acidity of the vagina, often leading to the growth of pathogenic bacteria, undesired biofilms, etc. Thus, certain embodiments of the present invention are directed to the modulation of two microbiome's of an individual at appropriately the same time, but whereby the modulation of one microbiome is to increase the quantity of SCFAs in a particular microbiome (e.g. one's gut microbiome), while at the same time, reduce the amount of SCFAs in another of the individual's microbiome (e.g. a woman's vaginal microbiome).
In the vaginal microbiota, microbial communities with a higher proportion of facultative and obligate anaerobes and low Lactobacillus species are associated with elevated inflammatory cytokine levels. Thus, certain embodiments of the present invention are directed to modulating the vaginal microbiome so as to increase the quantity of certain Lactobacillus species while decreasing the population of other bacteria that adversely affect the vaginal microbiome. For example, contrary to an individual's gut microbiome, which is benefited by the increased production of SCFAs, in various embodiments of the present invention, the amount of SCFAs is limited via the reduction of certain bacteria that produce SCFAs, and in particular lowering the amount of F. prausnitzii in a woman's vaginal microbiome.
Still other embodiments of the present invention are directed to modulation of various molecular factors that influence the resolution of inflammation, including but not limited to a prominent feature of the mucosal inflammatory microenvironment—hypoxia. Mucosal hypoxia promotes the active resolution of inflammation through a variety of mechanisms, including extracellular acidification, purine biosynthesis/salvage, the generation of specialized pro-resolving lipid mediators (i.e. resolvins) and altered chemokine/cytokine expression. Each of neutrophils, eosinophils, and macrophages play an important role in molding tissue microenvironments to program an active resolution response and dysregulation of such an inflammatory microenvironment results in the loss of tissue homeostasis. Rather than having a preferred lactobacillus-dominated vaginal microbiome, some women have a vaginal microbiome harboring a diverse community of anaerobic bacteria. In various embodiments of the present invention, probiotics and methods are used to reduce hypoxic conditions of a woman's vagina to thwart the populations of undesired anaerobic bacteria.
As described generally in related earlier applications, e.g. U.S. Pat. Nos. 9,408,88; and 9,457,007, one of skill in the art will appreciate that several embodiments of the present invention are directed to a suitable topical composition comprising a population of bacteria as described herein included in the form of a cream, lotion, emulsion, gel, ointment, liquid or spray. In one embodiment, the topical composition is formulated to provide at least about 10.sup.2 bacteria per cm.sup.2. In another aspect, a method of treatment is provided, wherein a composition as described herein is topically applied to the skin (e.g. vagina) of an expectant mother at around the time of birth, and also preferably during the first year of the baby's life. In certain embodiments, topically applying includes topically applying to a mucosal surface of the vagina of the expectant mother and/or directly to the new born baby or to the skin/nipple of the mother prior to breastfeeding the infant. In one preferred embodiment, a topical vaginal lotion comprises a mixture of Lactobacillus johnsonii, and Bifidobacterium lognum bacteria and is applied just prior to birth to provide an opportunity for the newborn to be first exposed to such bacteria, thus enhancing the chances that the baby's immune system will properly form in a manner that avoid allergies.
In certain embodiments, an intitial step in the modulation of a woman's vaginal microbiome is to reduce if not eliminate the bacterium Gardnerella vaginalis, as its biofilm is recalcitrant and is believed to be central to the development of dysbiosis and is responsible for still further undesired pathobiont biofilms being formed in the vagina. Reduction of this bacterium by use of antibiotics, CRISPR systems, bacteriophages, etc. form one of several mehtods for reducing the number of G. vaginalis prior to the purposeful administration to and modulation of a woman's vagina with desired bacertia as referrenced herein. Bacterial vaginosis (BV) is characterized by a depletion of Lactobacillus and an overgrowth of anaerobic and facultative bacteria, leading to increased mucosal inflammation, epithelial disruption, and poor reproductive health outcomes. Thus, the focus on reducing Gardnerella vaginalis and the administration of beneficial bacteria to a woman's vagina is one way to achieve a desired bacterial balance necessary for a healthy vaginal microbiome.
In accordance with another aspect of the present invention, certain embodiments are directed to a method that includes introducing ammonia oxidizing microorganisms (AOM) to a woman's vagina, and preferably live AOM. The ammonia oxidizing bacterium Nitrosomonas eutropha is employed in various embodiments of the present invention to enhance the health aspects of a woman's vagina. While N. eutropha bacteria is preferred in various embodiments, one of skill in the art will appreciate that other bacteria can be employed that have similar ammonia generation attributes, which may be provided to a given bacteria via the modification thereof, such as via use of a CRISPR system to include such functional characteristic.
In still other embodiments of the present invention, a baby's first bath is prepared such that it contains a concoction of a rich variety of lactobacillus and other immune enhancing agents to prevent the life-threatening diseases as discussed herein. In addition to a variety of various beneficial bacteria described herein, helminthes extracts, as also set forth or referenced herein, may be provided in a suitable lotion/ointment, that includes sugars that the various lactobacillus microorganisms may assimilate to survive and thrive. These sugars and bacteria supporting compounds are known to those in the art and as otherwise referenced in various incorporated writings. As certain spermicides and contraceptive creams can kill Lactobacillus species, it is one aspect of particular embodiments of the present invention to avoid the use of such formulations during pregnancy and during the first year of a newborn's life, as the prevalence of a rich variety of lactobacillus, as noted herein, is a desired objective to achieve in the overall environment of the expectant mother and the newborn for the first year of life. In this vein, preferably there is an avoidance of any type of aerosol sprays that could also kill bacteria in the environment of the expectant mother and the newborn.
A preferred bacteria that proliferates on the cocktail of compounds in mother's milk is Bifidobacterium longum biovar infantis (B. longum by. Infantis). This bacterium is believed to enter the infant's intestinal tract in one of several ways, including when the fetus swallows amniotic fluid, when the fetus passes through the vaginal tract in a vaginal birth, and when the infant is provided with mother's milk. While there are hundreds of human milk oligosaccharides (HMOs) the B. longum by. Infantis preferentially feast on the same to develop a colony of bacteria in the infant gut, thus leading to further enhancement of the developing immune system of the infant. The HMOs also directly ward off harmful bacteria, such as Salmonella, Listeria and Campylobacter. HMOs also mimic carbohydrate structures on the infant's gut and thus are believed to swamp the infant's system so that these dangerous bacteria bind to the HMOs rather than to the infant's developing gut, e.g. in a type of competitive defensive mechanism that is known in other natural systems. It is important to have a developed infant immune system that has a sufficient and significant number of B. longum by. Infantis, which is correlated with the amount of mother's milk provided—but only if there is a resident and sufficient population of B. longum by. Infantis in the first place. This bacterium makes up about 90% of the population of the gut of an infant, which is striking in that only about 3% of the adult gut is inhabited by this bacteria.
As one of skill in the art may appreciate, because the present inventors contend that there exist complexities with respect to the beneficial bacteria residing in a woman's vagina, as contrasted with the beneficial bacteria in an individual's gut, (for example, with respect to the amount of SCFAs produced by such respective bacteria and the benefits (or conversely the detriment) that are associated with such bacteria), this factor must be properly considered when formulating treatment plans for the modulation of each individual's particular microbiome. This is especially the case when one considers the vaginal seeding with bacteria that will presumably colonize the gut and skin microbiomes of infants. Thus, in certain embodiments of the present invention, a factor that has hereto been underappreciated, namely the importance of varying the bacterial type, amount and metabolites associated with a healthy vagina microbiome, while also taking into account the preferred bacteria that best benefits an infant's gut microbiome, one of skill in the art will recognize that subtle, but important, modulations of both the mother's vaginal microbiome and the infant's gut microbiome should be assessed, rather than simply believing that whatever microbiome the infant is exposed to by the mother is beneficial, let alone preferred. Stated differently, a desirable bacterial composition for a “normal” vaginal microbiome may not be the preferred bacterial composition to first colonize an infant's gut microbiome. For example, with C-section deliveries, attention should be paid to purposeful inoculation of an infant's microbiomes—including not just the infant's gut microbiome, but also its skin microbiome. Aspects of the present invention involve the administration to a newly born infant with a variety of pre-determined bacterial formulations for each of the infant's gut and skin microbiome, which in many cases, are not identical to the vaginal microbiome of the mother of the infant at the time of birth.
In preferred embodiments, certain microbes from the genus Lactobacillus, and more particularly, the species Lactobacillus johnsonii, are employed. L. johnsonii is a known human gut colonizer and becomes a dominant member of the maternal vaginal microbiome just before birth. In order to suppress allergic symptoms, it is believed effective to lean the immune balance towards “Th1-type” dominant, and generally, lactic acid bacteria are said to have an activity to lean the immune balance towards “Th1-type” dominant. In one embodiment, Lactobacillus crispatus KT-11 strain (FERM BP-11332) is used to lead the immune balance towards “Th1-type dominant”, with such strain used in combination with other lactic acid bacteria belonging to the genus Lactobacillus, genus Bifidobacterium, genus Leuconostoc, genus Enterococcus, and genus Pediococcus.
While L. johnsonii is a preferred bacteria in many embodiments, other bacteria are employed in various embodiments, such bacteria selected from the group consisting essentially of Lactobacillus acidophilus, Lactobacillus brevis, Lactobacillus buchneri, Lactobacillus casei, Lactobacillus delbrueckii, Lactobacillus fermentum, Lactobacillus helveticus, Lactobacillus kefir, Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus rhamnosus, Lactobacillus salivarius, Streptococcus thermophilus, Lactococcus lactis, Lactococcus plantarum, Lactococcus raffinolactis, Leuconostoc lactis, Leuconostoc mesenteroides, Enterococcus faecalis, and Enterococcus faecium; an anti-allergic agent comprising as an active ingredient human-derived bifidobacteria selected from Bifidobacterium infantis, Bifidobacterium breve, Bifidobacterium longum, and Bifidobacterium bifidum; Enterococcus faecalis and Lactobacillus reuteri, and Lactobacillus paracasei.
In certain embodiments, a method for enhancing immunity of a newborn infant includes the use of a mixed culture of bacterial cells of three to eight species of lactic acid bacteria. In particular mixed cultures, the following may be included: Saccharomyces cerevisiae, Lactobacillus delbrueckii, Lactobacillus acidophilus, Lactobacillus plantarum, Lactobacillus fermentum, Lactobacillus casei, Lactobacillus rhamnosus, Lactococcus lactis and Streptococcus thermophilus; Enterococcus faecium; Bacillus coagulans; Leuconostoc, Pediococcus, Lactobacillus casei, Lactobacillus plantarum, Lactococcus lactis subspecies lactis, Lactococcus lactis subspecies cremoris; Lactobacillus plantarum; Pediococcus pentosaceus; Streptococcus thermophilus; Lactobacillus paracasei; Lactobacillus plantarum, Lactobacillus gasseri and Lactobacillus salivarius; Lactobacillus acidophilus PM-A0002, Lactobacillus gasseri, Lactobacillus salivarius, Lactobacillus acidophilus PM-A0013; Leuconostoc mesenteroides; Lactobacillus bulgaricus, Lactobacillus rhamnosus, Lactobacillus acidophilus, Lactobacillus paracasei; Bifidobacterium bifidum; Lactobacillus brevis; Enterococcus durans, Leuconostoc mesenteroides; Lactobacillus crispatus. Still other embodiments of the invention may comprise extracts obtained from one or more of the following species: Lactobacillus fermentum, Lactobacillus rhamnosus, Lactobacillus plantarum, Lactobacillus johnsonii, Lactobacillus helveticus, Lactobacillus casei defensis, Lactobacillus casei ssp. casei, Lactobacillus paracasei, Lactobacillus bulgaricus, Lactobacillus paracasei, Lactobacillus acidophilus, Lactobacillus reuteri, Lactobacillus salivarius, and Lactobacillus lactis. In some embodiments, at least one strain from each of the above species of bacteria is used, while in other embodiments, one or more specific strains from the list above may be removed or substituted with one or more different strains. In particular, some embodiments of the present invention comprise an extract obtained from one or more of the following bacterial strains: Lactobacillus fermentum 1-3929, Lactobacillus rhamnosus 71.38, Lactobacillus plantarum 71.39, Lactobacillus johnsonii 103782, and Lactobacillus helveticus 103146. The strains above are deposited according to the Budapest Treaty. Lactobacillus fermentum 1-3929, Lactobacillus rhamnosus 71.38, Lactobacillus plantarum 71.39, Lactobacillus johnsonii 103782, and Lactobacillus helveticus 103146 are each deposited at the Collection Nationale de Culture des Microorganismes at the Institut Pasteur, 25 rue du Dr. Roux, 75724 Paris, France. Lactobacillus fermentum 1-3929 was deposited on Feb. 27, 2008. The other strains are among the depository's collections and may be obtained by contacting the depository. The following bacteria species may also be employed: Lactobacillus acidophilus PM-A0002 deposit number M 207038, Lactobacillus gasseri PM-A0005 deposit number M 207039, Lactobacillus salivarius PM-A0006 deposit number M 207040, Lactobacillus johnsonii PM-A0009 deposit number M 207041 and Lactobacillus acidophilus PM-A0013 deposit number M207042. Certain embodiments of the present invention involve the use of bacteria obtained from Amish manure-containing soils.
In preferred embodiments, the environment whereby the expectant mother is exposed is devoid of significant levels of lead. It is speculated that the metal lead is a common environmental pollutant in inner cities and in older houses, released from factories and during mining operations. It is believed that lead disrupts normal immune system development, leading to increased frequency of the development of allergies and asthma. Lead exposure during critical, prenatal periods of development can impact immune system function well after birth. It is speculated that in the presence of lead exposure, the fetal immune system is changed so it overreacts to common particles in the environment. Thus, one aspect of the present invention is to avoid exposure of an expectant mother to lead, while at the same time, exposing such mother to significant levels of microbes and fungi obtained and derived from farms having manure containing soil collected from certain Amish farms, especially those that do not employ significant amounts of antibiotics in treating their cows, sheep, pigs, goats or poultry. Similarly, it is one aspect of the present invention for the expectant mother to desist from the use of anti-bacterial soap, as such use is believed to inhibit the immunity conferring benefits to be derived from the present invention. It is further believed that bacteria and other microbes from soil containing manure from bovines raised by the Amish (as well as other farm animals) and where neither the animals nor the manure is treated with an anti-biotic, is more effective as a source of desired microbes and allergens responsible for conferring the protective immunologic attributes that pass from an expectant mother to her unborn child. In a preferred embodiment of the invention, the child, after he or she is born, is further exposed to the manure containing soil that the expectant mother was exposed to during the pregnancy. In such a manner, it is believed that the early exposure to allergens is reinforced and permits the immune system to fully protect the child from such allergens. In other words, the child's immune system is permitted to more fully mature under the influence of continued exposure to the same type of microbes and fungi as was the mother during pregnancy.
Incomplete resolution of inflammation negatively impacts a woman's reproductive health. In contrast to other mucosal sites, the structure and function of the female vagina is tightly regulated by ovarian sex hormones progesterone and estradiol as their levels fluctuate throughout the menstrual cycle. Such fluctuating sex hormone levels influence immune cell function.
In the vaginal microbiota, microbial communities with a higher proportion of facultative and obligate anaerobes and low Lactobacillus species are associated with elevated inflammatory cytokine levels. Thus, certain embodiments of the present invention are directed to modulating the vaginal microbiome so as to increase the quantity of certain Lactobacillus species while decreasing the population of other bacteria that adversely affect the vaginal microbiome. For example, contrary to an individual's gut microbiome, which is benefited by the increased production of SCFAs, in various embodiments of the present invention, the amount of SCFAs is limited via the reduction in the vagina of certain bacteria that produce SCFAs, and in particular lowering the amount of bacteria that produce SCFAs, especially butyrate, in a woman's vaginal microbiome. SCFAs are the predominant metabolites in dysbiosis of the vaginal tract. Thus, lactic acid and SOFA metabolites represent biomarkers of disease in the vagina, while in the human gut, SCFAs have an anti-inflammatory role by inhibiting proinflammatory cytokines.
Lactobacilli including L. crispatus, L. gasseri, L. iners, L. jensenii, etc, are desirable because of protective properties, which include the production of lactate to lower vaginal pH and the production of bacteriocin and hydrogen peroxide, which provide an antimicrobial environment for pathogenic microorganisms and limit their growth. Lactobacilli break maltose into lactic acid in the glycolysis pathway in anaerobic conditions which regulate the vaginal pH lower than 4.5 and are responsible for vaginal acidity in healthy women. Lactic acid and hydrogen peroxide (H2O2) production by Lactobacilli and low pH are anti-microbial factors that protect against the colonization of pathogens. In various embodiments of the present invention, preferred concentrations of lactic acid are as high as 120 mM in the lower genital tract, with a concentration of acetic acid of 0-4 mM. In certain embodiments of the present invention, a topical application of Lactobacillus crispatus to an individual's vagina is done to reduce inflammation through production of tryptophan metabolites.
In dysbiotic vaginal conditions, certain undesired bacteria, such as Prevotella, Gardnerella, Bacteroides, Mobiluncus, Atopobium, Mycoplasma, Ureaplasma, Sneathia, Streptococcus, Eggerthella, Dialister, Leptotrichia, Finegoldia, Megasphaera, Veillonella, and Clostridiales are often dominant and these anaerobes species do not produce much lactic acid, instead they break glycogens into glucose and SCFAs metabolites, such as butyrate, propionate, succinate, and especially acetate. BV-associated anaerobes species are responsible for the fishy odor of vaginal discharge and can generate virulence factors that can stimulate immune responses. When vaginal pH elevates more than 4.5, epithelial barrier integrity is compromised, mucin degrades, and therefore BV and other female genital tract disorders increase.
SCFAs influence the immune system's operation by boosting T and B cell differentiation to control antigen-specific adaptive immunity and inhibiting dendritic cell migration and activation to reduce allergies. SCFAs have a positive effect on the gut mucosa by enhancing epithelial integrity, differentiation, and proliferation as well as decreasing the release of pro-inflammatory chemicals from mucosal epithelial and immune cells. But they are not deemed in a positive light with respect to their function in the female genital tract mucosa. Vaginal and cervical epithelial cells secrete pro-inflammatory molecules in response to high amounts of SCFAs and thus exacerbate, rather than alleviate, mucosal barrier functions and BV problems.
Mucus is one of the essential elements of the barrier function at the mucosa of the female reproductive system. L. crispatus-dominated vaginal microbiota capture microorganisms more effectively compared to mucus associated with vaginal microbiota dominated by Gardenella and L. iners. But mucus can become impaired if BV-associated bacteria degrade it. For example, a beneficial component of the mucus in the female reproductive system, sialic acid, is aggressively degraded by Prevotella, Gardnerella, and Bacteroides. Thus, in certain embodiments of the present invention, one step includes the reduction in the populations of one or more of Prevotella, Gardnerella, and Bacteroides in the vaginal microbiome to preserve the mucus in the vagina.
High concentrations of SCFAs cause vaginal epithelial cells to produce pro-inflammatory mediators. Higher concentrations of SCFAs in the human vaginal along with a decrease in lactate in BV leads to microbiota dysbiosis, which results in pathogen growth and can cause infection, leading to adverse reproductive outcomes such as miscarriage and preterm birth.
In contrast to the vaginal microbiome, Firmicutes and Bacteroidetes make up more than 90% of all the gut microbiota. The most abundant bacterial species in the gut of healthy adults is Faecalibacterium prausnitzii of the Firmicutes phylum. In the gut microbiome, Firmicutes species are the main butyrate producers, while Bacteroidetes species are the main acetate and propionate producers in the gut. In contrast to the gut, the predominant organic acid in a healthy vagina is lactic acid. The transfer of microbes between gut and vagina is possible, and so one would think the microbial composition of both would be similar. However, due to differing characteristics of these two microbiomes, different species thrive and become dominant in each, such that while the metabolites lactate, acetate, butyrate, succinate and propionate are present in both microbiomes, they exist in completely different concentrations and reflect contrary health conditions.
In still other embodiments of the present invention, a woman's vagina is administered a therapeutically effective amount of tomatidine to achieve benefits that are related to the intrinsic properties of tomatidine, such as its involvement in causing cell growth, and in its defense against pathogenic bacteria, viruses and fungi. Especially when administered in conjunction with bacterial species as identified herein, for example, AOM bacteria, the combination of tomatidine and such bacteria is believed to enhance the health of a woman's vaginal microbiome.
SOFA and lactate are also implicated in the onset of infection and virulence of fungal pathogens, such as Candida. Thus, one aspect of various embodiments of the present invention involves the reduction in the amount of SOFA production by vaginal bacteria to reduce the population of Candida.
Preferably, in various embodiments of the present invention, women are administered vaginal microbes of the aerotolerant anaerobic Lactobacillus bacteria, specifically L. crispatus, L. gasseri, L. iners, and L. jensenii. In contrast to other microbiomes, with respect to the vaginal microbiome, non-diverse Lactobacillus dominated microbiomes are considered healthy. As lactobacilli make up the vast majority of the vaginal microbiome, a large amount of metabolites present in the vaginal niche, mainly lactate, are produced by these species. L. crispatus dominated microbiomes have a high lactate content. While lactate is the main fermentation end product of lactobacilli, L. jensenii also produces high amounts of acetate and succinate.
BV-associated species are responsible for producing SCFAs and during BV, lactate levels are lowered, while the concentration of SOFA increases. BV-associated species that produce organic acids are: Peptococcus (butyrate and acetate production), Dialister (propionate production), Gardnerella vaginalis (acetate and succinate production), Bacteroides (succinate production), gram-positive cocci, and Clostridium (caproate production). Thus, certain embodiments of the present invention are directed to the selective reduction in the number and population of these BV related bacteria.
In particular embodiments of the present invention, tomatidine is administered to a woman to enhance the health of her vaginal microbiome. Such administration may be either oral or vaginal—or both. It is believed that tomatidine has an anti-atrophic (anabolic) effect in skeletal muscle and possesses anti-hyperlipidemic and anti-atherosclerotic effects without evidence of toxicity. Tomatidine is associated with anti-apoptotic, anti-inflammatory, anti-bacterial, and anti-cancer properties and appears to suppress inflammation by inhibiting the NF-κB and JNK signaling pathways.
In other embodiments of the present invention, in addition to the described bacterial formulations set forth, rapamycin is included to enhance the health of a woman's vaginal microbiome. Rapamycin targets is a kinase called mTOR which plays a role in a variety of biological pathways. Rapamycin is an inhibitor of mTOR complex (mammalian target of rapamycin) which is a serine threonine kinase and a master regulator of protein synthesis, cell growth, and cell metabolism. Excessive mTORC1 activity has been implicated in multiple disease conditions, as well as various cancers, inflammatory bowel disease, inflammatory skin diseases and neurodegenerative diseases. In various embodiments of the present invention, rapamycin is employed, especially in combination with other agents, e.g. tomatidine and xylitol, to treat, prevent and to reduce the likelihood of an individual suffering from vaginal disorders and diseases.
In various embodiments as described herein, administration of therapeutically effective amounts of rapamycin, e.g. by vaginal administration, is employed to combat disorders associated with age.
In certain embodiments, DNA encoding pre-cursors for the biosynthesis of tomatidine, xylitol and/or rapamycin is inserted into the genome of one or more bacterial species by employing CRISPR-Cas or CPf1 systems, such that an individual can orally take a pill containing such modified bacteria and in such a manner, effectively administer tomatidine, xylitol and/or rapamycin to the individual in a manner that does not require injections or the taking of traditional pharmaceutical formulations. Administration of rapamycin may be performed to affect about 0.001 mg to 30 mg total per day as an effective dose, preferably at least about 0.1 mg per day, with a preferred blood level of rapamycin in the subject being about 0.5 ng per mL whole blood after administration of the composition after a 24 hour period.
One embodiment of the present invention is directed to a bioadhesive strip adapted to bind to a mucosal membrane for at least 1 hour while inside a woman's vagina where the strip includes tomatidine and xylitol in therapeutically effective amounts, E.g. at least 10 micro-mole of tomatidine and at least 200 mg of xylitol or at least 0.2% xylitol by weight. In preferred embodiments, the strip includes at least one polymer selected from the group consisting of pullulan, hydroxypropylmethyl cellulose, hydroxyethyl cellulose, sodium alginate, polyethylene glycol, tragacanth gum, guar gum, acacia gum, arabic gum, carboxyvinyl polymer, amylose, high amylose starch, hydroxypropylated high amylose starch, dextrin, chitin, chitosan, levan, elsinan, collagen, zein, gluten, soy protein isolate, whey protein isolate, casein and mixtures thereof. In other embodiments, such strips may also include the beneficial vaginal bacteria described herein, as well as pre- and post biotic materials to maintain populations of such bacteria in the vagina.
Certain embodiments of the present invention are directed to treating vaginal dysbiosis so as to forestall women from experiencing serious infections. The various Lactobacillus probiotics as described herein are employed to reverse vaginal microbiota dysbiosis by facilitating the colonization of certain Lactobacillus species in a woman's vagina. For example, in certain embodiments, a combination of Lactobacillus acidophilus, Lactobacillus rhamnosus, and Lactobacillus reuteri are employed, in combination with a composition containing carbohydrates that feed such bacteria and promote their growth in a woman's vagina, all the while monitoring that the pH of the vagina does not exceed 4.5. While such compositions may be vaginally administered, they may also be administered orally, to improve vaginal health.
The gut, vaginal, and urinary microbiomes are mutually influential, and dysbiosis of one of these microbiota may result in several health problems. Menopause alters the gut, vaginal, and urinary microbiota due to drastic hormone changes. The gut microbiome of women influences bone metabolism and has a profound effect on bone quantity, quality, and overall strength. The gastrointestinal tract contains the highest concentration of immune cells that communicate with the microbial community, which triggers a release of metabolites that affect the immune system directly. The intestinal epithelial barrier plays a crucial role in separating the internal structures, with intestinal epithelial cells being sealed by tight junction proteins, such as ZO-1, claudin-1, and occludin. One aspect of various embodiments of the present invention is directed to altering the expression of tight junction proteins to alter the permeability of the intestinal barrier. If the intestinal barrier is breached, it allows microorganisms to enter the subepithelial structures from the intestinal metastatic lumen, and triggers an inflammatory response, often resulting in the development of osteoporosis, especially in postmenopausal women. Various embodiments of the present invention are directed to increasing probiotic function to increase the strength of the intestinal epithelium by upregulating tight junction proteins, reducing antigen presentation and activation of intestinal immune cells.
One aspect of many embodiments of the present invention is directed to modulation of the changes in a woman's microbiome, and in particular the vaginal microbiome, due to postmenopausal changes to alleviate and control postmenopausal health. Menopause-induced hormonal changes significantly alter the gut microbiome and hormone therapy can restore the microbiome to some degree. In various embodiments of the present invention, bacteria are administered to women to reduce the pH of their vaginas where the reduction of estrogen production has resulted in an increase of vaginal pH. This is accomplished by the administration of bacteria that affect the vaginal pH, notably the administration of Lactobacillus so as to positively influence the changes that are otherwise observed in vaginal structure and function in view of the onset of genitourinary syndrome of menopause. Menopause alters the gut microbiota, which has several effects on a woman's health. Moreover, the urinary microbiome plays an important role in urinary tract disease in the ovulatory cycle and certain hormones have substantial effects on the composition of such microbiome. Estrogen and progesterone cause thickening of the stratified squamous epithelium of the vagina and the deposition of glycogen. Alterations in the microbiota due to postmenopausal hormone changes are similar to vaginal dysbiosis observed in inflammatory pelvic disease, human immunodeficiency virus and human papillomavirus (HPV) infections, and pregnancy. Urinary pathogens are believed to originate in the gastrointestinal tract, with an intermediary step of vaginal colonization. Therefore, changes in the gut and vaginal microbiome as a result of dramatic hormonal changes during menopause impact the urinary microbiome. As disclosed herein, the modulation of both a woman's gut and vaginal microbiomes, with the understanding that the levels of SCFAs are distinct in each, forms one aspect of various embodiments of the present invention.
Postmenopausal women have a higher Firmicutes/Bacteroidetes ratio and a higher relative abundance of Lachnospira and Roseburia compared to premenopausal women, while premenopausal women have a lower relative abundance of the Prevotella, Parabacteroides, and Bilophila genera. Increased Bilophila in menopausal women leads to increased hydrogen sulfide production, inducing local inflammation and mucosal damage, increased serum endotoxin concentrations, and inflammatory reactions in several types of tissues. Thus, various embodiments of the present invention are directed to modulation of an individual's microbiome to address such changes by effective administrations of particular bacteria to distinct microbiomes.
Various embodiments are directed to balancing a woman's microbiome by increasing populations of gut microbiome bacteria to address an imbalance due to a deficiency of Aggregatibacter segnis, Bifidobacterium animalis, and Acinetobacter guillouiae. Moreover, other embodiments are directed to increasing populations of Romboutsia, Mollicutes, and Weissella spp. and in reducing populations of Fusicatenibacter, Lachnoclostridium, and Megamonas spp.
Certain aspects of the present invention are directed to methods for determining particular bacterial species, specifically those of Bifidobacterium, using computational biology to associate consortia with health span and longevity, thus permitting the treatment of age-related diseases. For example, certain methods employ a temporal microbiome characterization of healthy individuals—such as during the first and last stages in life—to elucidate Bifidobacterium that are most likely to confer health benefits.
Certain aspects of the present invention are directed to the mitigation of the decline of Bifidobacterium in the underlying mechanisms of aging. Bifidobacteria are gram-positive, anaerobic, non-motile, non-spore-forming, polymorphic rods that belong to the family Bifidobacteriaceae, order Bifidobacteriales and phylum Actinobacteria. The genus Bifidobacterium encompasses approximately 80 species, including four species Bifidobacterium animalis, B. longum, B. pseudolongum and B. thermacidophilum. in addition to the presence in the human gut, bifidobacterial species are present in the human vagina. Certain aspects of the present invention are directed to modulation of an individual's microbiome by increasing the population of bifidobacterial species in a woman's vagina.
Still other embodiments of the present invention are directed to increasing the populations of bacteria in one or more of the genera Lactobacillus, Brevundimonas, and Odoribacter while decreasing the quantity/populations of bacteria in the genus Streptococcus, thus treating women suffering from premature ovarian insufficiency.
In various embodiments, retention of the normal bacteria flora in terms of species of bacteria is preferred, but while maintaining such diversity of bacteria, the particular strains of such species are modified so as to reduce levels of undesired compounds normally generated by such bacteria, while at the same time maintaining, if not increasing, the level of desired products.
Various embodiments of the present invention are directed to increasing/enhancing the population in a woman's vagina of Lactobacillus, and more preferably at least two, and preferably at least three of the following: Lactobacillus crispatus, Lactobacillus iners, Lactobacillus jensenii, and Lactobacillus gasseri.
The antimicrobial effect of lactic acid is strongly pH dependent as only the protonated form of the acid has antimicrobial properties. At slightly higher pH, lactate does not exhibit similar antiviral nor antibacterial activity.
Lactobacilli are the dominant microbiota in the vagina and the administering of prebiotics can stimulate the growth of lactobacilli so as to maintain the preferred flora of the vaginal ecosystem. For example, in certain embodiments, prebiotic ogigosaccharides are employed to support the probiotic properties of L. crispatis, L. jensenii and L. vaginalis.
The functional contributions of bifidobacteria to health and well-being of adults is largely unexplored, and thus, aspects of the present invention are directed to microbiota enrichment with rationally selected strains of Bifidobacterium more adapted to the adult host, and especially the roles played by Bifidobacterium in the gut ecosystem across various host ages, and specifically with respect to Bifidobacterium animalis subsp. Lactis, and Bifidobacterium adolescentis, with modulation of an individual's gut microbiome to reflect that such bacteria are present in at least 20% of relative abundance in an individual's gut microbiota. Thus, various embodiments are directed to the purposeful enrichment of the adult gut microbiota with Bifidobacterium to support short- and long-term human health.
In still further embodiments, in addition to increasing levels of butyrate provided to an individual's gut microbiome so as to achieve the various benefits as described herein, some embodiments include the provision of tributyrin, preferably via a fermented form of tributyrin. Tributyrin is an organic compound having the chemical formula C15H26O6. Butyrate is the conjugate base of butyric acid while tributyrin is a prodrug of butyric acid, with a preferred IUPAC name Propane-1,2,3-triyl tributanoate. In such a manner, it is possible to provide individuals with a direct delivery of butyrate to the large and small intestine via cleaving by a lipase. Thus, while several embodiments of the present invention involve providing bacteria to an individual so as to produce/generate SCFAs in their gut microbiome, namely butyrate, other embodiments include an exogenous method of increasing butyrate in the gut of an individual that is independent of butyrate-producing bacteria, fiber requirements, etc. In certain preferred embodiments, at least about 300 mg of tributyrin is provided to an individual of the fermented form of tributyrin, more preferably at a level of at least about 500 mg, and even more preferably by providing doses in the 500-1000 mg range. In a similar manner, other embodiments involve the provision to an individual of both tributyrin and tracetatin (e.g. acetates bound to glycerol) in combination. While not bound by theory, it is believed that a combination of acetate and butyrate, as well as other SCFAs, provide health benefits to an individual. In preferred embodiments, methods of the present invention involve the provision of around a 1:3 ratio of triacetin and tributyrin, e.g. (250 mg triacetin+750 mg tributyrin) which is preferably orally delivered/administered to promote bone health and to maintain optimal levels of SOFA levels during aging. In addition to butyrate, one of skill in the art will appreciate that in other variants of the present invention, one may use sodium butyrate (having a chemical formula Na(C3H7COO) to achieve various objectives, as it is the sodium salt of butyric acid. Such objectives include the inhibition of proliferation, induction of differentiation, and/or induction of the repression of gene expression. Similarly, calcium magnesium butyrate can be employed in other embodiments of the present invention as it is more stable than sodium butyrate and is less hygroscopic.
Certain embodiments of the present invention are directed to establishing in an individual a mutually symbiotic flora of microorganisms, in particular of the genus Lactobacillus, able to colonize a healthy vagina, thereby protecting its host from vaginal infections. The acidity of a healthy vagina of a woman is due to the degradation of secreted glycogen/glucose to lactic acid and acetate by lactobacilli, providing for conditions that are unfavorable for the growth of many pathogenic microorganisms. An imbalance in the vaginal microbiota may result in overgrowth of pathogenic microorganisms, resulting in dysbiosis, inflammation and/or infections, leading to vaginitis, bacterial vaginosis, vaginal candidiasis and trichomoniasis. Thus, certain embodiments are directed to achieving and maintaining a balanced environment in a woman's vagina to reduce or deter the growth of pathogenic microorganisms and to foster the growth of beneficial bacteria. In certain embodiments, this is accomplished by employing novel compositions and methods that include live biotherapeutics to treat individuals based on differences between a gene-specific characterization of an individual's microbiome and a reference gene catalog of a human microbiome. Still other methods involve the purposeful colonization of a woman's vagina with beneficial bacteria just prior to a baby's birth so that the newborn baby is primarily exposed to such bacteria to foster the robust development of an immune system, believed to avoid the prospect of allergies, asthma, multiple sclerosis, type-1 diabetes, and other autoimmune diseases from developing by the infant.
Menopause alters the gut, vaginal, and urinary microbiota due to drastic hormone changes. To address such issues, several embodiments of the present invention are directed to administering bacteria to women during menopause to reduce the pH of their vaginas, thus effecting a reduction of estrogen production that is a result of an increase of vaginal pH. Other aspects of various embodiments involve reducing the prospects of osteoporosis by combatting the disruption of bone metabolism due to the increased expression of pro-inflammatory factors, including methods that employ administration to an individual of particular beneficial bacteria, tomatidine, etc. Such bacterial formulations reduce the likelihood of degenerative joint disease, chronic pain and disability involving articular cartilage breakdown, synovial inflammation, and bone hypertrophy.
Antibiotic exposure of a mother can affect the maternal vaginal microbiome composition and thus, has an effect on neonatal stool microbiomes. While there is some debate about the value of “vaginal seeding” to affect, restore and/or maintain an infant's microbiome, the present inventors believe that the presence of antibiotic exposure severely warps the ability to properly analyze the situation. Thus, while some believe that vaginal seeding appears to be transient and only evident immediately after birth prior to the impact of breastfeeding and other environmental exposures, the present inventors contend that such infant exposure to beneficial microbes has as yet unappreciated benefits to the infant. Together with beneficial bacteria being administered, e.g. via other maternal microbiomes, such as those of the breast milk and maternal gut, vaginal seeding with compositions of the present invention are believed to be valuable and worthwhile, particularly with respect to the vertical transfer of maternal strains to the early infant gut. While not bound by theory, it is believed that the purposeful modulation of the vaginal microbiome prior to a baby's birth, can trigger life-long immune responses, thus affecting the infant's ability to naturally develop its immune system in a manner that precludes the later suffering of asthma, allergies, etc. Identical strains from the genera Ruminococcus, Bifidobacterium. Bacteroides and members of the Clostridiales order have been identified in mother-infant pairs by multiple independent groups in the early days and weeks of life. Certain embodiments of the present invention are directed to providing at least two of these bacteria and contacting a woman's vagina therewith prior to the birth of her baby so as to ensure contact between the baby and the seeded vagina during the birthing process.
Certain aspects of the present invention relate to the appreciation that a healthy vaginal microbiome can be dominated by Bifidobacterium sp., a group of Gram-positive, anaerobes that are known to colonize the human vagina, oral cavity, and the gastrointestinal tract where they play an important role in the protection from pathogens through the production of bacteriocins. Bifidobacterium are capable of producing lactic acid and tolerate a low pH, important in maintaining a healthy vaginal fluid. Thus, certain embodiments of the present invention include compositions of both Bifidobacterium spp. and Lactobacillus spp. to achieve the desired result of preventing vaginal colonization by pathogenic organisms.
In certain embodiments, a particular microbial composition is employed comprising three distinct Lactobacillus crispatus strains, LUCA009, LUCA011, and LUCA103, (preferably all isolated from the human vaginal tract of healthy women, referred to herein as VM-02 as a functionally defined microbial composition). Preferred embodiments provide formulations that are rationally designed vaginal synbiotic formulations such that data may be generated demonstrating the coexistence and exertion of biological activity in the human urogenital system. The underlying concept to create a proactive approach rather than reactive care for vaginal health needs is unique from empiric approaches employed in the global probiotics category. In preferred embodiments, a live consortium is delivered as a suppository with additional ingredients which provide a supportive vaginal environment and serve as growth substrates for the bacterial strains.
Bacterial formulations of various embodiments are formulated based on (i) intra-species genetic diversity/pan-genomic coverage within the consortium, which confers temporal stability of the healthy microbiota (ii) resilience of the vaginal microbial community against fluctuations, such as menses and pathogen introduction, (iii) genetic synergy, following ecological principles that enable the strains' persistence and co-functionality; and (iv) strains which play a key role in the healthy vaginal ecosystem via acidification and production of antimicrobial compounds.
In contrast to prior art technologies that utilize a single strain of Lactobacillus, in preferred embodiments at least three strains are employed based on the genomic and metabolomic driven reconstitution of a vaginal microbial ecosystem consisting of multiple strains with minimal non-redundant genes. In one preferred embodiment, VM-02 is employed to achieve a desired balanced vaginal microbiome so as to promote and foster improved vaginal health. In various embodiments, an objective is to target an underlying microbial dysbiosis with an interventional probiotic to change the microbial composition, resulting in achieving an optimal vaginal health status through a conversion to a protective vaginal microbiome community state. Thus, in various embodiments an objective is to provide a multi-strain symbiotic intervention that is safe, well-tolerated, and an efficacious means to improve vaginal health. The result of employing such technology is the achievement of a conversion to a more protective vaginal microbiome community state, even in healthy, using an interventional probiotic, and with the delivery vehicle and mode of administration being a key component for successful strain persistence.
The vagina is the most likely source of bacteria that infects the urinary tract. A healthy vaginal microbial environment, however, is believed to decrease the risk of rUTI. A unique set of Lactobacillus species play key protective roles against pathogens in the vagina by lowering the environmental pH through lactic acid production, producing various bacteriostatic and bactericidal compounds, and by competitive exclusion. Lactobacillus crispatus species is generally considered to be associated with health, as it does not induce a vaginal mucosal inflammation, and it is also associated with protection from pathogens.
In a preferred embodiment, vaginal suppository is employed to modulate the vaginal microbiome to a state non-permissive to reinfection. The vaginal suppository is preferably supported by an oral monosaccharide, D-mannose, that acts locally, once excreted into the urinary tract to prevent binding of a causative pathogen to uroepithelial cells.
One will appreciate that this Summary of the Invention is not intended to be all encompassing and that the scope of the invention nor its various embodiments, let alone the most important ones, are necessarily encompassed by the above description. One of skill in the art will appreciate that the entire disclosure, as well as the incorporated references, figures, etc. will provide a basis for the scope of the present invention as it may be claimed now and in future applications. While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in this specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention.
As used herein, the terms “effective amount” and “amount effective” refer to an amount that is sufficient to achieve the desired result or to influence an undesired condition. For example, a “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generally insufficient to cause adverse side effects. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed and like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of a compound at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products, such as xylitol, rapamycin and tomatidine. In further various aspects, a preparation can be administered in a “prophylactically effective amount”; that is, an amount effective for prevention of a disease or condition. In various embodiments, an effective amount of rapamycin may be 50 to 250 micrograms; or between 0.1% to 20% of rapamycin based on total weight of the formulation; or at least 0.1 mg of rapamycin; or a dose of rapamycin in the range of 1 mg/day to 5 mg/day, and in other embodiments, in the range from about 0.01.mu.g/day to about 50.mu.g/day. In certain embodiments, the effective amount of tomatidine is at least 10 micro-mole of tomatidine; and at least 200 mg of xylitol or at least 0.2% xylitol by weight.
In certain embodiments of the present invention, a topical application of Lactobacillus crispatus to an individual's vagina is done to reduce inflammation through production of tryptophan metabolites. It is believed that such tryptophan metabolites act as AHR agonists. One of skill in the art will appreciate that embodiments may incorporate live bacteria, metabolites of these bacteria, postbiotics from these bacteria, and/or heat killed bacteria. In one particular embodiment, live bacterial cells of Lactobacillus crispatus are administered to an individual's vagina at a dosage of at least 10.sup.8 CFU, preferably in a moisturizing topical formulation, so as to reduce inflammation through the localized production of tryptophan metabolites. While not bound theory, it is believed that the localized production of tryptophan metabolites by L. crispatus acts as AHR agonists in keratinocytes. Preferably the L. crispatus bacteria formulation is further combined with a source to maintain the bacteria for a pre-determined time. In certain embodiments, such a formulation includes glycogen. In still other embodiments, a prebiotic for L. crispatus is provided, such prebiotic which may also include glycogen, and even more preferably it further includes a stimulant for the production of ceramide by keratinocytes. One or more skin moisturizing agents may be included, including, for example, skin barrier integrity-enhancing ingredients, such as PEA/MEA bioactive lipids, N-acetyl cysteine, nicotinamide, luteolin, and/or madecassoside. Again, while not bound by theory, bacterial formulations of the present invention include at least one bacteria that generates metabolites that act as AHR agonists. Preferred metabolites comprise tryptophan metabolites, such as indole-3-aldehyde or indole-3-acetic acid, as well as those that may reduce inflammation and/or those that inhibit thymic stromal lymphopoietin (TSLP) in keratinocytes in an AHR dependent manner. It is believed that AhR activation may suppress upregulation of TSLP expression. In preferred embodiments, L. crsipatus is employed under conditions such that specific metabolites are generated that act as AHR agonists, thereby resulting in the reduction of vaginal inflammation. In preferred embodiments the metabolites generated via the use of L. crispatus comprise tryptophan metabolites, including at least one of the following: indole-3-acetic acid, Indole-3-ethanol, Indole-3-pyruvate, indole-3-aldehyde. Thus, aspects of various embodiments of the present invention include the use of a live bacterial topical probiotic product that modulates AhR expression through the localized production of tryptophan-derived bacterial metabolites. Preferred topical formulations include a combination of live L. crispatus, prebiotic glycogen, and at least one barrier-enhancing/moisturizing compound.
In various embodiments, L. crispatus can be employed in various bacterial formulations to enhance the health of an individual's vagina. Preferably, L. crispatus is included with amounts of other ingredients, including at least one of probiotics, prebiotics, and other beneficial ingredients. In certain embodiments, at least one, but often at least two of L. reuteri and/or L. johnsonii and L. crispatus are used in a beneficial bacterial composition for topical administration, with the objective being to generate desired amounts of metabolites sufficient to reduce inflammation, especially through the production of tryptophan metabolites, believed to act as AHR agonists. In one embodiment, live bacterial cells of Lactobacillus crispatus are administered to the surface of an individual's vagina at a dosage of at least 10.sup.8 CFU to reduce inflammation through the localized production of tryptophan metabolites. Preferably the formulation also includes glycogen and a stimulant for the production of ceramide. The metabolites produced by the L. crispatus applied to the kin include indole-3-acetic acid, IAid, Indole-3-Ethanol, Indole-3-pyruvate, and indole-3-aldehyde. Thus, the localized production of tryptophan-derived bacterial metabolites reduces the amount of inflammation the individual would otherwise experience. Preferred formulations include a combination of live L. crispatus, prebiotic glycogen, and at least one barrier-enhancing/moisturizing compound. In certain embodiments L. crispatus is combined with Human milk human milk glycans to facilitate the generation of beneficial tryptophan metabolites.
A particular method for reducing the likelihood of vaginal inflammation in an individual human being is directed to the administration of a therapeutically effective amount of a bacterial formulation comprising at least one, and preferably at least two, of a live bacteria selected from the group consisting of L. reuteri, L. johnsonii and L. crispatus, and Nitrosomonas eutropha. wherein at least some bacteria in the bacterial formulation have been modified by using a using a clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR associated protein (Cas) system or a CRISPR from Prevotella and Francisella 1(Cpf1) system to enhance the generation of a tryptophan metabolite.
In certain embodiments, tomatidine is administered to improve the vaginal health of an individual. Tomatidine is present in high amounts in the unripe green tomato and in much lower amounts in the ripe red tomato. This is consistent with a role for tomatidine in protecting the unripe tomato against consumption, with the reduction in tomatidine levels in the ripe fruit then enabling consumption of the fruit and dispersal of the seeds by the consumer. Moderate amounts of tomatidine can activate adaptive cellular stress responses in muscle cells and thus, counteract age-related dysfunction and degeneration.
While not bound by theory, it is believed that such administration of tomatidine extends the lifespan and healthspan of humans and other mammals by inducing mitochondrial hormesis via the induction of ROS production. This further entails the activation of certain cellular and antioxidant pathways, including the SKN-1/Nrf2 pathway, which results in increased mitophagy. The selective removal of damaged or dysfunctional mitochondria by mitochondrial autophagy, termed mitophagy, is believed to be a feature of a treatment to extend an individual's lifespan in a safe and effective manner. Mitophagy modulates bioenergetics and survival in various diseases by reducing redox and damage. Impaired mitophagy occurs in physiological aging, as well as in certain diseases, such as sarcopenia and also believed to be present in cachexia. In certain embodiments, the administration or delivery of certain noxious chemicals are believed to counteract aging and age-related disease by inducing adaptive hormetic stress responses in cells. In other embodiments, the inclusion of rapamycin administration is employed to improve the healthspan of humans as it is further related to mitophagy. The methods and systems as set forth herein are directed to the extension of human life span in a fashion that promotes healthy aging and counteracts disease processes related to age-related disease, including but not limited to osteoporosis.
Tomatidine administration as described in the present specification is believed to contribute to a delay in the physiological aspects of aging, and thus, is able to prevent, treat and reduce age-related diseases and conditions, including but not limited to those suffered primarily by women, e.g. osteoporosis. For example, it is believed that tomatidine increases mitochondria DNA content and muscle fitness and lowers adiposity, as well as decreases skeletal muscle atrophy. While not bound by theory, it is believed that the administration of tomatidine maintains homeostasis by modulating mitochondrial biogenesis and induces mild oxidative stress, which activates the above referenced pathways to induce mitophagy. The amount of tomatidine administered is believed to be important to achieve its desired age fighting effects, with at least about 10 micro-mole, and more beneficially with between about 25 micro-mole and 50 micro-mole being preferred. Moreover, administration of tomatidine is believed to increase the production in an individual of amounts of certain amino acids, such as free amino acids of leucine, threonine, tryptophan, arginine, histidine, valine, isoleucine, and methionine. Such administration is also believed to affect ROS regulation and metabolism. As aging is known to negatively affect mitochondrial quality and biogenesis, the use of tomatidine to enhance mitophagy can be employed to reduce the amount of neurodegeneration and cellular dysfunction of cell metabolism, especially by inducing an increase in Nrf2/ARE reporter activity. Upon activation by ROS, Nrf2 translocates from the cytoplasm of a cell to the nucleus, where it binds to the ARE region to transcriptionally activate genes encoding antioxidant proteins. Thus, tomatidine administration activates the Nrf2-ARE pathway by inducing cells to increase levels of ROS, resulting in the contribution to mitophagy induction. While not bound by theory, it is also believed that administration of tomatidine as described herein acts via multiple stress response pathways, such as, in addition to the Nrf2 pathway referenced above, through the activation of the mitochondrial unfolded protein response (UPR mt). Compromised mitochondrial quality and function is related to pathological aging and disease and the accumulation of damaged mitochondria within cells triggers apoptosis, inflammation and cell senescence. Sarcopenia is observed in aging individuals, with almost 25% of those over 60 years old experiencing the same, rising to over 50% by the age of 80. Tomatidine is believed to preserve muscle function during aging and therefore extends lifespan by improving mitochondrial quality by reducing muscle atrophy. Sarcopenia is therefore common in aging and is associated with the deterioration of muscle fiber cells and with infiltration of adipocytes and inflammatory immune cells, impairing the generation of new myocytes. In various embodiments of the present invention, the employment of tomatidine is not resultant from effects on muscle stem cells or immune cells, but rather, is directed to the effect that tomatidine has in influencing the muscle cells themselves as it is believed that the mechanism of action is directed to processes occurring within skeletal muscle fiber cells.
Various aspects of the present invention are directed to the induction of mitophagy by the administration of tomatidine, especially via the microbiome cells of an individual as otherwise described herein, so as to enhance the quality of the cellular mitochondrial pool and/or mitochondrial biogenesis. Support for this theory of action can be found, for example, in studies of premature aging disease, such as Hutchinson-Gilford progeria syndrome, caused by a mutation of the nuclear architectural proteins lamin A and C. Such patients showed profound growth delay and premature aging phenotypes, including cardiac muscle and skeletal muscle pathologies. It is known that Nrf2 activity contributes to premature aging and that activation of the Nrf2 pathway ameliorates such disease. One aspect of the present invention is therefore directed to the administration of tomatidine, in particular as described herein via expression by or in conjunction with various bacteria in an individual's microbiome, so that it triggers mitophagy and induces Nrf2 activation. A signaling role for ROS in the stimulation of mitophagy in cells under mild stress supports the use of tomatidine as described herein, as moderately elevated ROS levels have been seen as inducing mitophagy, which has the effect of clearing aged or dysfunctional mitochondria. If ROS levels are too high, however, or if mitophagy is compromised, mitochondrial dysfunction becomes exacerbated, demonstrating that ROS levels have a dynamic role in health and aging disease. Employment of tomatidine to achieve a moderate elevation of ROS levels is therefore one objective of various embodiments of the present invention, but with care not to achieve excessive ROS levels, thus accomplishing the desired goal of enhancing cellular stress resistance in a manner that is disease protective. Tomatidine is therefore preferably administered in effective amounts that induce a moderate increase in ROS levels that is necessary to trigger mitophagy without demonstrating mitochondrial dysfunction.
Tomatidine is not believed to have significant anti-microbial effects, at least when used alone. When co-administered with other compounds, however, it is believed that there is a synergistic effect and therefore, tomatidine is viewed as an antibiotic potentiator when used with ampicillin, etc. Preferably, tomatidine, in certain embodiments is used at a concentration of about 200 micro grams per mL. Thus, in several embodiments, the use of tomatidine administration in an individual is employed to synergistically enhance the action of various antibiotics against certain bacteria. Such synergistic effects are believed to be also accomplished when tomatidine expression/administration in an individual is coupled of the co-administration with at least one of the following: p53 protein, rapamycin, resveratrol, metformin, spermidine, xylitol, glucosamine and methylene blue.
Resveratrol (3,4′,5-trihydroxystilbene; C.sub.14H.sub.120.sub.3) is a polyphenolic phytoalexin found in grapes, berries, peanuts, and wines. Resveratrol has been viewed as an antioxidant, anti-inflammatory, anti-apoptotic, and anticancer agent. Moreover, it has been reported that resveratrol modulates mitochondrial function, redox biology, and dynamics in both in vitro and in vivo experimental models. Resveratrol also attenuates mitochondrial impairment induced by certain stressors. Resveratrol upregulates, for example, mitochondria-located antioxidant enzymes, decreasing the production of reactive species by these organelles. Resveratrol also triggers mitochondrial biogenesis, ameliorating the mitochondria-related bioenergetics status in mammalian cells. Brain cells (both neuronal and glial) are susceptible to mitochondrial dysfunction due to their high demand for adenosine triphosphate (ATP). Additionally, brain cells consume oxygen (O.sub.2) at very high rates, leading to a proportionally high mitochondrial production of reactive species. One aspect of various embodiments of the present invention is the maintenance of mitochondrial function in various cell types to address degenerative diseases, which involve mitochondrial impairment and increased generation of reactive species, leading, for example, to neuroinflammation and cell death. The mechanism by which resveratrol protects mitochondrial function and dynamics is not completely understood, but it is known that resveratrol is able to induce cytotoxicity depending on its dosage. Resveratrol produced by the microbiome of an individual (or precursors thereof) can be employed to improve the dysregulation of the gut microbiota induced by a high-fat diet, as it results in increasing the ratio of Bacteroides-to-Firmicutes and also increases the growth of Lactobacillus acidophilus and bifidobacterium in humans. It is believed that resveratrol modifies the intracellular environment by changing the oxidizing milieu into a reducing milieu and upregulates intracellular glutathione, potentiating a signal transduction cascade that results in mitophagy, and thus paves the way to an anti-aging environment.
Mammalian/mechanistic target of rapamycin (mTOR) is an intracellular protein complex that is responsive to both growth factors and nutrient availability, and which also impacts mitochondrial function. It is comprised of the TOR kinase—known as mTOR in mammals. The TOR signaling pathway is highly conserved in eukaryotes and is functionally defined as the target of the highly-specific antifungal, rapamycin. mTOR and aging appear to have co-evolved, suggesting that cancer is inexorably linked to fundamental aspects of life. Rapamycin can be employed, via production by or used in conjunction with an individual's microbiome, to achieve the objective of delaying the effects of aging and thus, reduce diseases associated with aging. Age-associated diseases interface with TOR and its signaling systems, and thus, employment of rapamycin (alone or in concert with the various other agents described herein) provides the ability to target both aging and its associated diseases.
In certain embodiments, precursors of one of xylitol, rapamycin and tomatidine are administered via an individual's own microbiome as a way to deliver a therapeutic treatment that works on everyone despite the distinct and acknowledged differences between an individual's microbiome. The differences of each individual's microbiome works in favor of this approach as delivery of rapamycin via one's own microbiome is naturally customed tailored as focusing on modification of an individual's microbiome provides desired anti-aging agents while maintaining the distinct character of an individual's microbiome. Aging is therefore possible to treat in a personalized way by taking into account the individual's unique microbiome. The present invention provides a way to tailor preventive measures and treatments to different individuals. Mechanical loading plays a major role in the regulation of skeletal muscle mass, and the maintenance of muscle mass profoundly influences health and quality of life. Signaling by the mammalian/mechanistic target of rapamycin (mTOR) is a key component of the mechanotransduction pathway. Employment of an individual's microbiome to administer effective amounts of rapamycin to the individual is one way in which to modulate mTOR signaling, thus affecting muscle mass and associated bone density.

Certain embodiments of the present invention are directed to bacterial production by genetically modified bacteria to produce or to be used in conjunction with one of xylitol, tomatidine and/or rapamycin, especially the precursors thereof such that biosynthesis of these agents can be provided to those in need. Bacteria that may produce xylitol include Corynebacterium sp., Enterobacterium liquefaciens, Serratia marcescens, Bacillus coagulans and Mycobacterium smegmatis. Certain embodiments of the present invention involve the production of xylitol by genetically modified bacteria, including those listed above, preferably using CRISPR systems to include genes responsible for xylitol production in yeasts, such as Pichia stipitis. The genes of yeasts that encode for xylitol production are well known by those of skill in the art. Incorporation of these genes into suitable bacterial vectors is within the skill of those in the art. For example, deletion of the Escherichia coli xylulokinase gene (xylB) is essential for achieving high xylitol titers from xylitol-producing E. coli strains growing on glucose in the presence of xylose. The yeast Pichia stipitis naturally produces xylitol. Replacement of xylB with XYL3 results in drastically enhanced xylitol titers from E. coli strains co-expressing xylose reductase during growth on xylose. Biological conversion of xylitol using microorganisms is achieved in some embodiments via using genetically modified microorganisms capable of converting readily available carbon sources, such as D-glucose, into xylitol.
In certain embodiments, a level of butyrate in an individual's gut microbiome is increased and such individual is provided with tributyrin. In others, the individual is separately administered a helminthes extract as the exposure of one's microbiome to such extract is believed to trigger effective immunity against certain conditions and diseases. In some preferred embodiments the at least two bacteria selected from the group consisting of Peptococcus, Dialister, Gardnerella vaginalis, Bacteroides and Clostridiu are reduced in the vagina of the individual being treated.
Other embodiments involve steps of reducing the amount of short chain fatty acid (SCFA) production in the individual's vagina by reducing a population of at least two of the following: Streptococcus, Bacteroides, Prevotella, Mycoplasma, Ureaplasma, Finegoldia, Mobiluncus, Leptotrichia, Eggerthella, Veillonella, Dialister, Atopobium, Megasphaera, Sneathia. C. albicans and Gardnerella vaginalis. Preferably at the same time that these bacteria are reduced in the vagina, there is an increase in SCFAs in the individual's gut microbiome. In various preferred embodiments, ammonia oxidizing microorganisms are introduced to an individual's vagina, e.g. N. eutropha, to achieve the health benefits otherwise disclosed herein. In other embodiments, using probiotics, the hypoxic conditions of an individual's vagina are reduced so as to combat and reduce any existing population of anaerobic bacteria in the individual's vagina. In many embodiments, one objective is to maintain a pH of the individual's vagina at below 4.5.
Certain embodiments of the present invention are directed to a method to reduce the likelihood of a dysbiosis of the vaginal microbiome in an individual, such method involving the provision a bacterial formulation that includes at least two species of live bacteria selected from the group consisting of L. reuteri, L johnsonii and L. crispatus. Preferably such bacterial formulation includes at least one prebiotic having glycogen as a component thereto. The bacterial formulation is administered to an individual's vagina in an amount sufficient for the bacterial formulation to generate an amount of tryptophan metabolites sufficient to act as aryl hydrocarbon receptor (AHR) agonists, thereby reducing inflammation in the individual's vagina. A preferred embodiment includes a bacterial formulation that includes L. crispatus and at least one of a probiotic, prebiotic, and a moisturizer. Such a bacterial formulation is preferably applied to an individual's vagina at night so that it remains thereon during a sleeping pattern of the individual. In other embodiments, the individual is further administered either or both tomatidine and rapamycin in therapeutically effective amounts due to the beneficial health aspects of such compounds as disclosed herein, and in a most preferred embodiment, is administered vaginally to be absorbed via the vaginal mucosal tissues of the individual. In certain embodiments, the administration of at least one of tomatidine and rapamycin is achieved using a bioadhesive strip that has a first and second side, with the second side having a bioadhesive that is adapted to bind to a mucosal membrane for at least 1 hour. Such strip may include a polymer selected from the group consisting of pullulan, hydroxypropylmethyl cellulose, hydroxyethyl cellulose, sodium alginate, polyethylene glycol, tragacanth gum, guar gum, acacia gum, arabic gum, carboxyvinyl polymer, amylose, high amylose starch, hydroxypropylated high amylose starch, dextrin, chitin, chitosan, levan, elsinan, collagen, zein, gluten, soy protein isolate, whey protein isolate, casein and mixtures thereof.
In several embodiments, the method is intended to treat a postmenopausal woman. In preferred embodiments, prior to the step of providing the bacterial formulation, a number of resident bacteria in the individual, namely in a woman's vagina, are reduced using one of an antibiotic, or a clustered regularly interspaced short palindromic repeats (CRISPR) CRISPR associated protein (Cas) system or a CRISPR from Prevotella and Francisella 1 (Cpf1) system. The later can be employed to selectively kill undesired and/or pathogenic bacteria without killing commensal bacteria that are desired. In certain embodiments, the population inside an individual's vagina is increased by providing a population of bacteria from one or more of the genera Lactobacillus, Brevundimonas, and Odoribacter. In other embodiments, the method further involves decreasing a population of bacteria of the genus Streptococcus in the individual's vagina. In still other embodiments, the method includes reducing in the individual's vagina a population level of the bacterium Gardnerella vaginalis.
Certain aspects of the present invention are directed to preserving mucus in the individual's vagina by reducing a population of bacteria in the individual's vagina selected from the group consisting of Prevotella, Gardnerella, and Bacteroides. In other embodiments, with the objective being to reduce a risk of a newborn infant developing one of infantile asthma, wheezing and allergies, the population of Veillonella and Lachnospira bacteria in a woman's vagina is reduced, preferably starting at the late stages of pregnancy, such as during the sixth or seventh month.
The maternal microbiome is essential for the healthy growth and development of offspring and has long-term effects later in life. Beginning as regulation of fetal health and development during pregnancy, the maternal microbiome continues to affect early microbial colonization via birth and breastfeeding and further regulates an infant's immune and brain development. and affects the risk of related diseases. Certain aspects of the present invention are directed to modulating offspring development by the probiotic intervention during pregnancy and breastfeeding.
While not bound by theory, it is believed that the abundance of Prevotella during a mother's pregnancy is closely related to the risk of food allergy in the infant, with a higher abundance of Prevotella in the maternal gut being indicative of a lower risk of food allergy in infants at 12 months. Thus, certain embodiments are directed to increasing the populations of Prevotella in the material gut during pregnancy. Moreover, certain maternal microbial metabolites (i.e. AhR ligands and SCFAs) and the cytokine-mediated response (IL-6) synergistically regulate the early establishment of immunity before birth. In certain embodiments, probiotic supplementation (especially in postmenopausal women) is employed as a way to manage menopause-related diseases. In particular embodiments, oral probiotic formulations including Lactobacillus ssp. casei, helveticus, rhamnosus, and reuteri—are administered due to their pleiotropic beneficial effects on health. Such bacterial formulations promote intestinal calcium absorption and delay potential bone damage for women at risk of osteoporosis or osteopenia.
In other preferred embodiments, exclusively L. crispatus bacteria are present in formulations and thus, certain claims are directed to formulations either consisting of or consisting essentially of select L. crispatus strains as described herein. Moreover, in preferred embodiments, there is added to the formulation a prebiotic that contains maltose, and more preferably consisting essentially of just maltose as a sugar and preferably not glycogen, as it is believed that maltose is a semi-selective fuel source for L. crispatus. In preferred embodiments, the bacterial formulation is administered as vaginal suppositories, even more preferably in the form of a slow-release tablet, which is preferably inserted with a device. Certain embodiments of the present invention include in a formulation the following: Maltose, Calcium L-lactate; L-glutamine Magnesium citrate dibasic and L-Cystine, with preferred embodiments consisting essentially of such ingredients, in addition to the L. crispatus strains as mentioned herein. L-glutamine is believed to serve as a building block for the L. crispatus cell wall. Glutamine is believed to be an amine donor in peptidoglycan biosynthesis and in the amidation of the aspartate residues in peptide cross-links. Magnesium citrate dibasic is believed to serve as a buffer to balance the acidifying activity of calcium lactate and Lactobacillus growth. L-Cystine (the oxidized dimeric form of cysteine) is believed to afford the creation and maintenance of a high positive redox potential in the vagina, favoring the growth of the select L. crispatus strains. Such formulation therefore confers host protection from numerous vaginal health conditions, reduces discharge and odors and confers other benefits like comfort and hydration. In other embodiments, oral administration of oral D-mannose is employed to help prevent undesired E. coli growth and is also believed to delay recurrent UTIs. It is believed that acid-tolerant L. crispatus in the consortium formulations set forth possess a growth advantage by accessing nutrients with enzymes that are optimally set to operate at a low pH. Preferred strain combinations are selected to include specific characteristics, including the asparagine synthase B gene, temporal stability, max unique genes, and the ability to inhibit vaginal pathogens UPEC, G. vaginalis, P. bivia, S. aureus, and S. Agalactiae. Together with the strains of L. crispatus, such formulation provides a superior vaginal product that facilitates a modification to the vaginal microbiome into a CST1 (L. crispatus dominant) ecology.
While not bound by theory, it is believed that five major kinds of vaginal communities with markedly different species composition (“community state types,” or CSTs) occur in reproductive-age women. CST's are defined by the dominant microbial species present: Lactobacillus crispatus (CST I), L. gasseri (CST II), L. iners (CST III), and L. jensenii (CST V). CST IV is typified by a lower proportion of lactic acid producing bacteria and a relatively higher proportion of anaerobic organisms including the species Gardnerella vaginalis. Vaginal microbiomes classified as CST1 are associated with vaginal health: L. crispatus does not elicit mucosal inflammation, is linked with prevention or reduction of the incidences of urogenital diseases such as bacterial vaginosis (BV), yeast infections, sexually transmitted infections (STIs), and urinary tract infections (UTI), as well as to positive impacts on fertility and reduction of adverse pregnancy outcomes, such as pre-term birth. Even within a protective CST1, the presence of specific L. crispatus strains may be associated with greater stability and resilience of the vaginal microbiome. Vaginal microbiomes containing such strains (including VM-02) returned to baseline more quickly after disruptions, such as menses.
In preferred embodiments, and using VM-02 as a representative example that one of ordinary skill in the art will appreciate as representative of a wider range of bacterial formulations, preferred embodiments are in a form of an extended-release mucoadhesive suppository vaginal tablet, such as a 850 mg oblong (17×7.8 mm) tablet. The following formulation (Table 1) represents the results of a batch production for the VM-02 consumer clinical trial to assess safety and tolerability.
VM-02 is comprised of 3 proprietary strains of live Lactobacillus crispatus bacteria (1×109 CFU each): L. crispatus LUCA011, L. crispatus LUCA103, and L. crispatus LUCA009. These VM-02 LUCA strains were rationally designed through a platform (e.g. the LUCA Biologics Platform); the strains are genetically synergistic and selected based on a) presence of a unique biomarker associated with resilience, b) maximizing unique gene content between strains and c) exceptional inhibition of uro-pathogenic E. coli (UPEC) and other pathogens that cause vaginal infections.
aWill differ per lot based on CFU/g obtained during production of individual L. crispatus strains.
bFiller-will differ per lot based on weight of L. crispatus strain used.
Additional ingredients may play a role in conditioning the local vaginal environment to support the growth and persistence of the probiotic strains. These ingredients can be found in the USP/NF compendium (with the exception of ammonium citrate which serves as a buffer and is ACS reagent grade), many of them commonly used as excipients, and each have been studied independently. They are commonly found in the human body, or are salts thereof, and most are commercially available dietary supplements.
The Supporting Ingredients Include:
Maltose: Serves as a carbon and energy source for the active L. crispatus strains. Maltose is a common breakdown product of host-produced glycogen in the vaginal epithelium.
Calcium L-Lactate: a stable salt of lactic acid, which is commonly used in tableting and for vaginal acidification. Acid-tolerant L. crispatus in the consortium has a growth advantage by accessing nutrients with enzymes that are optimally set to operate at low pH.
L-glutamine: serves as a building block for the L. crispatus cell wall. Glutamine is used as an amine donor in peptidoglycan biosynthesis and in the amidation of the aspartate residues in peptide cross-links.
Magnesium citrate dibasic: serves as a buffer to balance the acidifying activity of calcium lactate and Lactobacillus growth.
L-Cystine: the oxidized dimeric form of cysteine and is commonly found in the vaginal environment. The addition of cystine affords the creation and maintenance of a high positive redox potential in the vagina, favoring the growth of L. crispatus.
Chemically inactive excipients may be used as either filling or binding agents in order to form a tablet or powder. The excipients that may be used in the formulations are commonly used pharmaceutical excipients and are below the amounts listed in FDA's Inactive Ingredient Database (IID). The inactive excipients that facilitate the VM-02 tablet and capsules and their intended functions within the formulation are as follows:
Cellulose Microcrystalline (Vivapur 200xLM): large size MCC grade with excellent flow properties for a variety of direct compression formulations.
Magnesium stearate (Ligamed MF2V): can result in a good speed of release during tablet pressing and constant performance of the tablets such as hardness and dissolution profiles.
HPMC [Metolose 905H15000] is used as a binder for solid dosage forms such as tablets and granules.
A preferred vaginal suppository of one embodiment of the present invention is comprised of three strains of live L. crispatus bacteria (1×10 9 CFU): L. crispatus LUCA009, L. crispatus LUCA011, and L. crispatus LUCA103, in addition to excipients to aid the activity of such L. crispatus stains, and the excipients used to manufacture the tablet. Preferably, these strains are isolated from clinical vaginal samples of healthy women with a stable, L. crispatus-dominant vaginal microbiome, and selected for consortium assembly based on their genetic synergy, following ecological principles that enable the consortium's persistence and co-functionality, for the prevention of recurrent urinary tract infection (rUTI) in premenopausal women. The tablet is intended to modulate the vaginal microbiome to a state non-permissive to reinfection in combination with an enteral monosaccharide that acts locally within the urinary tract to prevent binding of a causative pathogen to epithelial cells. By addressing both the intravaginal and urinary tract sources of urinary pathogens, the combinatorial treatment aims to eliminate the dual reservoirs of pathogens that lead to recurrence of UTIs while supporting the establishment of a resilient Lactobacillus population.
In a preferred embodiment, these L. crispatus strains predominate in a healthy vaginal microbiota and protect against colonization with uropathogens. The vaginal suppository is preferably administered concurrently with orally ingested D-mannose, which complements the bacterial formulation's intravaginal activity. It is believed that oral D-mannose helps to minimize bladder colonization with gram negative bacteria, especially E. coli, by blocking a receptor that allows bacteria to bind to the bladder epithelium, which is believed to delay the time to recurrent rUTIs. Oral D-mannose is a commonly used over-the-counter dietary supplement, which at higher doses can cause some diarrhea, but is generally well tolerated. One aspect of various embodiments is to employ both the bacterial formulation together with an orally ingested D-mannose in the management of urinary tract infections, due to their complementary mechanisms of action. Together this regimen provides a multi-pronged approach to address both urinary and vaginal reservoirs of pathogens and reduces UTI recurrence. In contrast to prior technologies utilizing a single strain of Lactobacillus, embodiments of the present invention employ at least three strains with minimal non-redundant genes to establish a genomic and metabolomic driven reconstitution of a vaginal microbial ecosystem.
In certain embodiments, methods involve an interventional treatment that comprises of administering a bacterial formulation comprising at least three strains (e.g. as identified above) in the form of a mucoadhesive tablet suppository (vaginal) in combination with oral monosaccharide D-Mannose, supplied in 2-gram sachets. Preferred intravaginal suppositories are 500 mg and oblong (17×7.8 mm) tablets. Table 1 above contains the components of interventional treatment: strains (active live biotherapeutic product) and supporting ingredients. In preferred embodiments, an oral monosaccharide is packaged in 2-gram sachets and stored at room temperature (25° C.), consisting of D-mannose, an OTC monosaccharide shown to block FimH adhesion protein of dominant causative pathogens in UTI.
