Atopic dermatitis (AD) is a common type of chronic inflammatory skin disease found in pets. Canines particularly suffer from atopic dermatitis as one of the primary reasons for a veterinary visit. Typically, atopic dermatitis is characterized by pruritus (itchiness), erythema (redness), skin and ear secretions and alopecia (hair loss). Thus, atopic dermatitis is considered to significantly reduce the quality of life for pets suffering from atopic dermatitis.
In addition to a reduced quality of life, pets suffering from atopic dermatitis often suffer from pruritic skin disorder and/or skin membrane barrier dysfunction. Skin barrier plays a critical role in preventing the entry of allergens and microorganisms into the body. The physical skin barrier is localized in the uppermost area of the epidermis called stratum corneum. Further, the epidermis is continuously regenerated by terminally differentiating keratinocytes, a process called keratinization or cornification. Cornification begins with the migration of keratinocytes from the basal to upper layers during which keratinocytes also produce lipids and extrude them into the extracellular space to form extra-cellular enriched layers to maintain skin membrane barrier function. In addition, the presence of cytokines within the skin influences various processes of keratinocyte proliferation, differentiation and cornification.
It is believed that a combination of genetic, environmental, and immunological factors influence the pathogenesis of atopic dermatitis as well as the extent of the harm from such atopic dermatitis.
There is a present need for treatments, compositions, and methods for alleviating pets suffering from atopic dermatitis and the effects thereof.
This summary is intended merely to introduce a simplified summary of some aspects of one or more implementations of the present disclosure. Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. This summary is not an extensive overview, nor is it intended to identify key or critical elements of the present teachings, nor to delineate the scope of the disclosure. Rather, its purpose is merely to present one or more concepts in simplified form as a prelude to the detailed description below.
Aspects of the invention are directed to pet food compositions and, particularly, pet food compositions comprising a botanical component. In accordance with a first aspect, provided is a pet food composition that includes an effective amount of a plurality of botanical ingredients selected from cinnamon, green tea, pomegranate, ginger, lime peel, tulsi, and a combination of two or more thereof.
According to another aspect of the invention, provided is a pet food composition that includes a fat; a protein; and a botanical component. The botanical component typically comprises three to six botanical ingredients selected from about 0.05 to about 2 wt. % of cinnamon; from about 0.05 to about 2 wt. % of green tea; from about 0.05 to about 2 wt. % of pomegranate; from about 0.005 to about 1 wt. % of ginger; from about 0.2 to about 3 wt. % of lime peel extract; and from about 0.0006 to about 1 wt. % of tulsi.
In accordance with a further aspect of the invention, a method is provided for pruritus, erythema, alopecia, or skin and ear secretion in atopic dermatitis canine, the method comprising administering a pet food composition disclosed herein. The method may include providing and/or feeding the canine a pet food composition disclosed herein. In some instances, the method may include providing and/or feeding the canine the pet food compositions for 1 or more days, preferably 5 or more days, preferably 7 or more days, preferably 10 or more days, preferably 14 or more days, preferably 30 or more days, or preferably 42 or more days.
The features, and advantages of the invention will be apparent from the following more detailed description of certain embodiments of the invention and as illustrated in the accompanying drawings in which:
It should be understood that the various aspects are not limited to the compositions, arrangements, and instrumentality shown in the figures.
For illustrative purposes, the principles of the present invention are described by referencing various exemplary embodiments thereof. Although certain embodiments of the invention are specifically described herein, one of ordinary skill in the art will readily recognize that the same principles are equally applicable to, and can be employed in other compositions and methods. Before explaining the disclosed embodiments of the present invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details of any particular embodiment disclosed. The terminology used herein is for the purpose of description and not of limitation.
As used herein and in the appended claims, the singular forms “a”, “an”, and “the” include plural references unless the context dictates otherwise. The singular form of any class of the ingredients refers not only to one ingredient within that class, but also to a mixture of those ingredients. The terms “a” (or “an”), “one or more” and “at least one” may be used interchangeably herein. The terms “comprising”, “including”, and “having” may be used interchangeably. The term “include” should be interpreted as “include, but are not limited to”. The term “including” should be interpreted as “including, but are not limited to”.
As used throughout, ranges are used as shorthand for describing each and every value that is within the range. Any value within the range can be selected as the terminus of the range. Thus, a range from 1-5, includes specifically 1, 2, 3, 4 and 5, as well as subranges such as 2-5, 3-5, 2-3, 2-4, 1-4, etc. The term “about” when referring to a number means any number within a range of 10% of the number. For example, the phrase “about 2 wt. %” refers to a number between and including 1.8 wt. % and 2.2 wt. %.
All references cited herein are hereby incorporated by reference in their entireties. In the event of a conflict in a definition in the present disclosure and that of a cited reference, the present disclosure controls.
The abbreviations and symbols as used herein, unless indicated otherwise, take their ordinary meaning. The abbreviation “wt. %” means percent by weight with respect to the pet food composition. The symbol “°” refers to a degree, such as a temperature degree or a degree of an angle. The symbols “h”, “min”, “mL”, “nm”, “μm” means hour, minute, milliliter, nanometer, and micrometer, respectively. The abbreviation “UV-VIS” referring to a spectrometer or spectroscopy, means Ultraviolet-Visible. The abbreviation “rpm” means revolutions per minute.
Any member in a list of species that are used to exemplify or define a genus, may be mutually different from, or overlapping with, or a subset of, or equivalent to, or nearly the same as, or identical to, any other member of the list of species. Further, unless explicitly stated, such as when reciting a Markush group, the list of species that define or exemplify the genus is open, and it is given that other species may exist that define or exemplify the genus just as well as, or better than, any other species listed.
All components and elements positively set forth in this disclosure can be negatively excluded from the claims. In other words, the pet food compositions of the instant disclosure can be free or essentially free of all components and elements positively recited throughout the instant disclosure. In some instances, the pet food compositions of the present disclosure may be substantially free of non-incidental amounts of the ingredient(s) or compound(s) described herein. A non-incidental amount of an ingredient or compound is the amount of that ingredient or compound that is added into the pet food composition by itself. For example, a pet food composition may be substantially free of a non-incidental amount of an ingredient or compound, although such ingredient(s) or compound(s) may be present as part of a raw material that is included as a blend of two or more compounds. Substantially free, unless other defined or described herein, typically refers to an ingredient or compound in an amount of about 2 wt. % or less, about 1.5 wt. % or less, about 1 wt. % or less, about 0.5 wt. % or less, about 0.1 wt. % or less, or about 0.05 wt. % or less, or about 0.01 wt. % or less, based on the total weight of the pet food composition on a dry matter basis.
Some of the various categories of components identified may overlap. In such cases where overlap may exist and the pet food composition includes both components (or the composition includes more than two components that overlap), an overlapping compound does not represent more than one component. For example, certain components or ingredients may be characterized as both an ancient grain and an amaranth. If a particular pet food care composition recites both an ancient grain and an amaranth, a compound that may be characterized as both an ancient grain and an amaranth will serve only as either an ancient or an amaranth—not both.
As used herein, the term “pet” could be used interchangeably with “companion animal” and refers to an animal of any species kept by a caregiver as a pet or any animal of a variety of species that have been widely domesticated as pets, including canines (Canis familiaris) and felines (Felis domesticus). Thus, a pet may include but is not limited to, working dogs, pet dogs, cats kept for rodent control (i.e. farm cats), pet cats, ferrets, birds, reptiles, rabbits, and fish.
To the extent that food and food ingredient contain water/moisture, the dry matter represents everything in the sample other than water including, for example, protein, fiber, fat, carbohydrates, minerals, etc. Dry matter weight is the total weight minus the weight of any water. The skilled artisan would readily recognize and understand nutritional amounts and percentages expressed as dry matter amounts, dry matter weights and dry matter percentages.
Dry matter intake per day is calculated as the total nutritional intake per day excluding all water. For example, an amount of an ingredient equal to a specific percent of daily nutritional intake refers to the amount of that ingredient in dry matter form (i.e., excluding all water) relative to the total amount of dry matter consumed (also excluding all water) in a day.
“Daily nutritional intake” and “total nutritional intake per day” refer to dry matter intake per day. That is, water weight is not included in calculating the amount of nutrition consumed per day. To calculate percent of an ingredient of total daily intake on a dry matter basis, water is removed from the total intake to give total daily dry matter intake and the percentage of the ingredient is based on amount of ingredient present as dry matter.
As used herein, an “ingredient” refers to any component of a pet food composition. The term “nutrient” refers to a substance that provides nourishment and thus has a nutrient value. In some cases, an ingredient may comprise more than one “nutrient,” for example, a composition may comprise corn comprising important nutrients including both protein and carbohydrate.
Aspects of the invention are directed to pet food compositions and, particularly, pet food compositions comprising a botanical component. The botanical component comprises a plurality of botanical ingredients. Botanical ingredients are generally ingredients that are derived and/or extracted from plants, such as from roots, stem, fruits, leaves, and/or flowers of plants. The botanical ingredients may be in the form of an aqueous extract, an organic extract, or an oil based extract. A botanical ingredient, such as a botanical extract, may contain a plurality of active compounds, which may be associated with one or more benefits. An extract may optionally contain other non-bioactive compounds, which may or may not be associated with any in-use benefits.
The botanical component may be present in the pet food composition in an amount from about 0.1 to about 15 wt. %, based on the total weight of the pet food composition on a dry matter basis. For example, the pet food composition may contain a botanical component in an amount from about 0.1 to about 10 wt. %, about 0.1 to about 8 wt. %, about 0.1 to about 6 wt. %, about 0.1 to about 5 wt. %, about 0.1 to about 4 wt. %, about 0.1 to about 3 wt. %, about 0.1 to about 2 wt. %, about 0.1 to about 1 wt. %; from about 0.4 to about 15 wt. %, about 0.4 to about 10 wt. %, about 0.4 to about 8 wt. %, about 0.4 to about 6 wt. %, about 0.4 to about 5 wt. %, about 0.4 to about 4 wt. %, about 0.4 to about 3 wt. %, about 0.4 to about 2 wt. %, about 0.4 to about 1 wt. %; from about 0.8 to about 15 wt. %, about 0.8 to about 10 wt. %, about 0.8 to about 8 wt. %, about 0.8 to about 6 wt. %, about 0.8 to about 5 wt. %, about 0.8 to about 4 wt. %, about 0.8 to about 3 wt. %, about 0.8 to about 2 wt. %; from about 1.3 to about 15 wt. %, about 1.3 to about 10 wt. %, about 1.3 to about 8 wt. %, about 1.3 to about 6 wt. %, about 1.3 to about 5 wt. %, about 1.3 to about 4 wt. %, about 1.3 to about 3 wt. %; from about 1.8 to about 15 wt. %, about 1.8 to about 10 wt. %, about 1.8 to about 8 wt. %, about 1.8 to about 6 wt. %, about 1.8 to about 5 wt. %, about 1.8 to about 4 wt. %, about 1.8 to about 3 wt. %; from about 2.4 to about 15 wt. %, about 2.4 to about 10 wt. %, about 2.4 to about 8 wt. %, about 2.4 to about 6 wt. %, about 2.4 to about 5 wt. %; from about 2.8 to about 15 wt. %, about 2.8 to about 10 wt. %, about 2.8 to about 8 wt. %, about 2.8 to about 6 wt. %, about 2.8 to about 5 wt. %, or any range or subrange thereof, based on the total weight of the pet food composition on a dry matter basis. The pet food compositions may be formulated to contain an effective amount of a botanical component to provide at least a 10% increase in arginine metabolic pathway compounds and/or products thereof, such as ornithine, citrulline, argininosuccinate, and/or hydroxyproline, at about 24 hours after a pet consuming the pet food composition for at least 5 consecutive days. In some preferred embodiments, the pet food composition provides an increase of at least 15%, at least 20%, at least 30%, at least 40%, at least 60%, or at least 80% in arginine metabolic pathway compounds and/or products thereof at about 24 hours after a pet consuming the pet food composition for at least 5, at least 7, at least 10, or at least 42 consecutive days.
The pet food compositions disclosed herein typically comprise a plurality of botanical ingredients selected from cinnamon, green tea, pomegranate, ginger, lime peel, tulsi, and a combination of two or more thereof. Preferably, the pet food composition comprises three to six botanical ingredients, which may be selected from cinnamon, green tea, pomegranate, ginger, lime peel, tulsi, and a combination of two or more thereof. The inventors surprisingly discovered pet food compositions having a botanical component comprising certain combinations of botanical ingredients and/or compounds unexpectedly achieved reductions in symptoms associated with atopic dermatitis in canines consuming such pet food compositions.
In accordance with one aspect of the invention, provided is a pet food composition that includes an effective amount of a plurality of botanical ingredients selected from cinnamon, green tea, pomegranate, ginger, lime peel, tulsi, and a combination of two or more thereof. In some embodiments, the plurality of botanical ingredients includes three, four, five, or six botanical ingredients. For example, the plurality of botanical ingredients may include three to six, three to five, or three or four botanical ingredients. According to one embodiment, the plurality of botanical ingredients may include four to six, four or five, or five or six botanical ingredients.
The botanical component preferably includes one or more botanical ingredients selected from cinnamon, green tea, pomegranate, ginger, lime peel, and tulsi. In some cases, the botanical ingredients may be selected from cinnamon, green tea, pomegranate, ginger, lime peel, and a combination of two or more thereof. In further cases, the botanical ingredients may be selected from cinnamon, green tea, pomegranate, ginger, tulsi, and a combination of two or more thereof. Preferably, the pet food composition comprises two or three botanical ingredients selected from cinnamon, green tea, pomegranate, and ginger. In at least one embodiment, the pet food composition comprises each of the following botanical ingredients: cinnamon, green tea, pomegranate, and ginger.
The pet food compositions may be formulated to include not more than six botanical ingredients. For instance, the pet food composition may have a botanical component consisting of three to six botanical ingredients selected from cinnamon, green tea, pomegranate, ginger, lime peel, tulsi, and a combination of two or more thereof. In some embodiments, the botanical component may consist of three, four, five, six, or any range formed therefrom of botanical ingredients selected from cinnamon, green tea, pomegranate, ginger, lime peel, and/or tulsi. In at least one instance, the botanical component includes botanical ingredients (such as, three or four botanical ingredients) selected from the group consisting of cinnamon, green tea, pomegranate, ginger, and a combination of two or more thereof.

For example, the additives may be present in an amount from about 0.01 to about 5 wt. %, about 0.01 to about 4 wt. %, about 0.01 to about 4 wt. %, about 0.01 to about 3 wt. %, about 0.01 to about 2 wt. %, about 0.01 to about 1 wt. %; about 0.1 to about 5 wt. %, about 0.1 to about 4 wt. %, about 0.1 to about 4 wt. %, about 0.1 to about 3 wt. %, about 0.1 to about 2 wt. %, about 0.1 to about 1 wt. %; about 1 to about 5 wt. %, about 1 to about 4 wt. %, about 1 to about 4 wt. %, about 1 to about 3 wt. %, about 1 to about 2 wt. %; about 2 to about 5 wt. %, about 2 to about 4 wt. %, about 2 to about 4 wt. %, about 2 to about 3 wt. %; about 3 to about 5 wt. %, about 3 to about 4 wt. %; or about 4 to about 5 wt. %, based on the total weight of the pet food composition on a dry matter basis. In some embodiments, the concentration of such additives (particularly where such additives are primarily nutritional balancing agents, such as vitamins and minerals) is from about 0 to about 2.0% by weight, based on the total weight of the pet food composition on a dry matter basis. The amount of additives comprising vitamins may be in addition to the amount of vitamin B discussed above. In some embodiments, the concentration of such additives (again, particularly where such additives are primarily nutritional balancing agents) is from about 0 to about 1.0% by weight, based on the total weight of the pet food composition on a dry matter basis. Although the list of foregoing additives may be potentially suitable in some embodiments, one or more of the foregoing additives may be excluded from other embodiments of the pet food composition.
In specific embodiments, the pet food compositions and food products are formulated to address specific nutritional differences between species and breeds of animals, as well as one of more of the attributes of the animal. For example, cat foods, for example, are typically formulated based upon the life stage, age, size, weight, body composition, and breed.
Sources of proteins, carbohydrates, fats, vitamins, minerals, balancing agents, and the like, suitable for inclusion in the pet food compositions, and particularly in the food products to be administered in methods provided herein, may be selected from among those conventional materials known to those of ordinary skill in the art.
The pet food compositions may include, or in some instance exclude, one or more ingredients selected from beef broth, brewers dried yeast, egg, egg product, flax meal, DL methionine, amino acids, leucine, lysine, arginine, cysteine, cystine, aspartic acid, polyphosphates, sodium pyrophosphate, sodium tripolyphosphate; zinc chloride, copper gluconate, stannous chloride, stannous fluoride, sodium fluoride, triclosan, glucosamine hydrochloride, chondroitin sulfate, green lipped mussel, blue lipped mussel, methyl sulfonyl methane (MSM), boron, boric acid, phytoestrogens, phytoandrogens, genistein, diadzein, Lcarnitines, chromium picolinate, chromium tripicolinate, chromium nicotinate, acid/base modifiers, potassium citrate, potassium chloride, calcium carbonate, calcium chloride, sodium bisulfate; eucalyptus, lavender, peppermint, plasticizers, colorants, flavorants, sweeteners, buffering agents, slip aids, carriers, pH adjusting agents, natural ingredients, stabilizers, biological additives such as enzymes (including proteases and lipases), chemical additives, coolants, chelants, denaturants, drug astringents, emulsifiers, external analgesics, fragrance compounds, humectants, opacifying agents (such as zinc oxide and titanium dioxide), antifoaming agents (such as silicone), preservatives (such as butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA), propyl gallate, benzalkonium chloride, EDTA, benzyl alcohol, potassium sorbate, parabens and mixtures thereof), reducing agents, solvents, hydrotropes, solubilizing agents, suspending agents (non-surfactant), solvents, viscosity increasing agents (aqueous and non-aqueous), sequestrants, keratolytics, egg shell membrane, ancient grain, and a combination of two or more thereof.
The pet food composition may be produced by various methods to achieve the desired pet food composition or desired form for the pet food composition. For example, dry food may be baked or extruded, then cut into individual shaped portions, such as kibbles. In some embodiments, the pet food composition may be prepared in a canned or wet form using conventional food preparation processes known to those of ordinary skill in the art. Typically, ground animal proteinaceous tissues are mixed with the other ingredients, such as cereal grains, suitable carbohydrate sources, fats, oils, and balancing ingredients, including special purpose additives such as vitamin and mineral mixtures, inorganic salts, cellulose, beet pulp and the like, and water in an amount sufficient for processing. The ingredients are mixed in a vessel suitable for heating while blending the components. Heating the mixture is carried out using any suitable manner, for example, direct steam injection or using a vessel fitted with a heat exchanger. Following addition of all of the ingredients of the formulation, the mixture may be heated to a temperature of from 50° F. to 212° F. Although temperatures outside this range can be used, they may be commercially-impractical without the use of other processing aids. When heated to the appropriate temperature, the material will typically be in the form of thick liquid, which is dispensed into cans. A lid is applied and the container is hermetically sealed. The sealed can is then placed in convention equipment designed for sterilization of the contents. Sterilization is usually accomplished by heating to temperatures of greater than 230° C. for an appropriate time depending on the temperature used, the nature of the composition, and related factors. The pet food compositions and food products of the present disclosure can also be added to or combined with food compositions before, during, or after their preparation.
In some embodiments, the food products may be prepared in a dry form using convention processes known to those of ordinary skill in the art. Typically, dry ingredients, including dried animal protein, plant protein, grains and the like are ground and mixed together. Liquid or moist ingredients, including fats, oils water, animal protein, water, and the like are added combined with the dry materials. The specific formulation, order of addition, combination, and methods and equipment used to combine the various ingredients can be selected from those known in the art. For example, in certain embodiments, the resulting mixture is process into kibbles or similar dry pieces, which are formed using an extrusion process in which the mixture of dry and wet ingredients is subjected to mechanical work at high pressure and temperature, forced through small openings or apertures, and cut off into the kibbles, e.g., with a rotating knife. The resulting kibble can be dried and optionally coated with one or more topical coatings comprising, e.g., flavors, fats, oils, powdered ingredients, and the like. Kibbles may also be prepared from dough by baking, rather than extrusion, in which the dough is placed into a mold before dry-heat processing.
In preparing a composition, any ingredient generally may be incorporated into the composition during the processing of the formulation, e.g., during and/or after mixing of the other components of the composition. Distribution of these components into the composition can be accomplished by conventional means. In certain embodiments, ground animal and/or poultry proteinaceous tissues are mixed with other ingredients, including nutritional balancing agents, inorganic salts, and may further include cellulose, beet pulp, bulking agents and the like, along with sufficient water for processing.
In accordance with a further aspect of the invention, a method is provided for pruritus, erythema, alopecia, or skin and ear secretion in atopic dermatitis canine, the method comprising administering a pet food composition disclosed herein. The method may include providing and/or feeding the canine a pet food composition disclosed herein. In some instances, the method may include providing and/or feeding the canine the pet food compositions for 1 or more days, preferably 5 or more days, preferably 7 or more days, preferably 10 or more days, preferably 14 or more days, preferably 30 or more days, or preferably 42 or more days. The method may include feeding the pet one time a day, two times a day, three times a day, or in some embodiments four or more times a day.
Three pet food compositions (Example Compositions A-C) were prepared by combining three botanical components with a base pet food composition (Control Composition 1). Control Composition 1 also served as a positive control for the following examples. The three botanical components, which were used for preparing Example Composition A-C, are shown in Table 1, below. The nutritional value of Example Compositions A-C and Control Composition 1 in Table 2, below.
Example Compositions A and B were evaluated in comparison to positive control, Control Composition 1. Specifically, 26 clinically diagnosed dermatological canines of both genders having ages ranging from 5.9 years to 16.9 years and body weights ranging from 8.3 to 21.5 kg were evaluated. All of the canines were being neutered or spayed.
The canines were sorted into three groups, with Group 1 having 7 dogs, Group 2 having 9 dogs, and Group 3 having 10 dogs. The dogs of Group 1 were fed Control Composition 1 for 60 days, the dogs of Group 2 were fed Composition 2 for 60 days, and the dogs of Group 3 were fed Example Composition A for 60 days, as part of a feed regimen. None of the canines underwent a pre-feed phase before receiving one of the pet food compositions for the 60 day period. Clinical assessment of dermatological health was assessed by a veterinarian using a prescribed questionnaire before starting the 60 day feed regimen to establish a baseline and at the end of 60 day feed regimen to determine the severity of pruritus, erythema, skin and ear secretions and alopecia.
Example Composition B was evaluated in comparison to Control Composition 1 to assess the effect of Example Composition B on canines suffering from dermatological problems. Specifically, 19 canines of mixed gender with ages ranging from 9.0 years to 16.9 years and body weights ranging from 7.5 to 25.6 kg were evaluated in this Example. All canines were canines clinically diagnosed with dermatological problems and were neutered or spayed.
The canines were separated into two groups by matching age and gender. The first group of canines was fed Example Composition B for a period of 42 days while the second group was fed Control Composition 1 for a period of 42 days as a first feed regimen. After the 42 days of the first feed regimen, the first group was fed Control Composition 1 for a period of 42 days and the second group was fed Example Composition B for a period of 42 days, as a second feed regimen. The canines did not undergo a pre-feed or washout feed regimen.
Blood samples were collected from each canine before starting the first feed regimen, after the first feed regimen, and after the second regimen. Clinical assessment of dermatological health was assessed by a veterinarian using a prescribed questionnaire before the first feed regimen, after the first feed regimen, and after the second regimen, to determine the severity of pruritus, erythema, skin and ear secretions and alopecia.
Additionally, the palatability of Example Composition B and Control Composition 1 was assessed to determine if the four botanical ingredients effected the palatability of Example Composition B. Although a two-bowl PAL test was not performed for this Example, the amount of Example Composition B and Control Composition 1 consumed by the canines was monitored to assess palatability and rejection of food.
Example Composition C was evaluated in comparison to Control Composition 1 to assess the effect of Example Composition C on canines suffering from dermatological problems.
Specifically, 20 canines having ages ranging from 9.0 years to 16.4 years and body weights ranging from 7.5 to 25.6 kg were evaluated in this Example. All canines were mixed gender, neutered or spayed, and clinically diagnosed with dermatological problems.
The 20 canines were then separated into two groups by matching age and gender. The first group was fed Example Composition C for a period of 42 days while the second group was fed Control Composition 1 for a period of 42 days as a first feed regimen. After the 42 days of the first feed regimen, the first group was fed Control Composition 1 for a period of 42 days and the second group was fed Example Composition C for a period of 42 days, as a second feed regimen. The canines did not undergo a pre-feed or washout feed regimen before the first or second feed regimens.
Blood samples were collected from each canine before starting the first feed regimen, after the first feed regimen, and after the second regimen for cytokines analyses. Clinical assessment of dermatological health was assessed by a veterinarian using a prescribed questionnaire before starting the first feed regimen, after the first feed regimen, and after the second regimen to determine the severity of pruritus, erythema, skin and ear secretions and alopecia.
As discussed above, Example 2 evaluated Example Compositions A and B in comparison to Control Composition 1, which was a positive control pet food composition. Based on Example 2, Example Composition B increased the response rate (improvement %) of pruritus and erythema compared with Example Composition A and Control Composition 1 (see
In Example 3, Example Composition B increased the response rate (improvement %) of pruritus, erythema and skin and ear secretions of dogs by 46%, 42% and 21% respectively, when compared with Control Composition 1 (see
Regarding Example 4, Example Composition C was evaluated in composition to Control Composition 1. It was determined that Example Composition C did not show any improvement of pruritus, erythema and skin and ear secretions of dogs compared with Control Composition 1 (see
Overall, Example Composition B reduced pruritus and erythema robustly when compared with Control Composition 1 and Example Compositions A and C, which would significantly improve the quality of a pet's life by reducing scratching and other behavior problems associated with chronic pruritus, which was not expected by the inventors.
The blood samples from the canines in Examples 3 and 4 were evaluated to assess the change in systemic immunity based on consumption of the pet food compositions. Specifically, the blood samples were evaluated to determine the change in circulating levels of 13 cytokines. In Example 3, the canines consuming Example Composition B exhibited a decreasing trend of all cytokines levels compared with the baseline and the canines consuming Control Composition 1 (see
In Example 4, it was determined that none of the cytokine levels showed a decreasing trend in canines consuming Example Composition C when compared to Control Composition 1. Control Composition 1 exhibited a decreasing trend of some cytokines levels in canines consuming Control Composition 1 when compared with the baseline (see
Overall, the circulating cytokines expression analysis suggests that Example Composition B reduces cytokine levels that are associated with the severity of atopic dermatitis to improve the quality of pet's life by reducing scratching.
In addition, a non-targeted metabolites analysis in serum samples collected from the Example 3 was preformed and it was determined that Example Composition B provide a significant decrease of circulating acylcarnitines levels (see Table 3, below) compared with the baseline but not with Control Composition 1. Acylcarnitines are the products of incomplete betaoxidation of fatty acids, which are conventionally believed to have the potential to activate proinflammatory signaling pathways.
Example Composition B also showed a significant increase of circulating long chain polyunsaturated fatty acids (PUFAs), such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), compared with the baseline, not with Control Composition 1. Long chain PUFAs are generally antioxidants, anti-inflammatory, and can attenuate food allergy (see Table 4, below).
Canines consuming Example Composition B exhibited a significant increase in the compounds utilized by the arginine metabolic pathway as well as its products, such as ornithine, citrulline, argininosuccinate, and hydroxyproline compared with the baseline, but not in comparison to canines consuming Control Composition 1 (see Table 5). This was unexpected because the dietary amino acids profiles in Example Composition B and Control Composition 1 are similar (see
Example Composition B provided a significant reduction of short chain length (<24) sphingomyelins and ceramides compared with the baseline, although not when compared with Control Composition 1 (see Tables 6 and 7, below). Increasing short chain length sphingomyelins and ceramides play an important role in impaired skin membrane barrier function in atopic dermatitis (AD). Accordingly, the inventors believe that reducing short chain sphingomyelins and ceramides probably plays a role in improving skin lipid layer homeostasis to improve skin membrane barrier function.
