The present disclosure relates to synbiotic composition, comprising probiotic bacterial strains and prebiotic fibres or oligosaccharides, for use in the prevention, amelioration, treatment, or reductions of symptoms in an individual suffering from Inflammatory Bowel Disease (IBD) or from an infection with a respiratory virus or from long-term effects after an infection with a respiratory virus.
During the last decades, the importance of the gut microbiota for wellbeing and health has been intensively studied. New knowledge has resulted in a suggestion to view the gut microbiota as a new organ. Molecular genetic methods have revolutionized the insight into the composition of the microbiota and microbiota analysis has made it possible to include studies of the microbiota as part of many human intervention studies. The gut with its microbiota has a key function to maintain immune homeostasis and approximately 70% of the immune system is estimated to be located in the gut.
Virus infections start with a virus entering the body and attaches to a virus receptor. After attachment, virus can enter into cells by different mechanisms and inside the cell the virus takes over the metabolism of the cell and multiplies. Some virus shares or partly shares receptors on the cell surface e.g. different upper tract respiratory viruses (Rhino-, Coxsackie- and Adenovirus). The immunoglobulin-like molecule CAR has been identified as a receptor for some types of Coxsackievirus and Adenovirus. Receptors for viruses usually have other functions besides being a receptor, e.g. ICAM (Intercellular adhesion molecule, also known as CD54 (Cluster of Differentiation 54)) occurs both as a soluble factor in serum and as a cell surface molecule. ICAM has been shown to be the receptor for Rhino- and Coxackievirus and is also important for the infection cycle of influenzavirus. The expression of ICAM has been shown to be enhanced in COVID-19 patients and patients with severe symptoms having the most enhanced expression. Another molecule with enhanced expression in COVID-19 patients is angiotensin and angiotensin converting enzyme (ACE). These proteins have been suggested to be important for attachment of SARS CoV-2-virus to the cell surface and have been observed to be more expressed in overweight persons and the elderly. This has been suggested to be one reason to that these two groups are at a high risk of getting a severe COVID-19 infection.
The incidence of upper respiratory tract infections is very high and some individuals suffer from several such infections per year. During the last year the coronavirus SARS-CoV2 has caused a pandemic of COVID-19, which in most individuals is a mild disease, but in some cases results in a life-threatening condition, requiring intensive care. In addition, COVID-19 can also result in prolonged illness and persistent symptoms, even in young adults and persons with no underlying medical conditions. There are very few effective treatments of upper respiratory tract infections and hardly no treatment for long-term effects of COVID-19.

Other objectives, features and advantages of the present disclosure will appear from the following detailed description, from the experimental data, as well as from the attached claims. It is noted that the disclosure relates to all possible combination of features.
Generally, all terms used in the claims are to be interpreted according to their ordinary meaning in the technical field, unless explicitly defined otherwise herein. All references to “a/an/the [component, means, step, etc.]” are to be interpreted openly as referring to at least one instance of said component, means, step, etc., unless explicitly stated otherwise. The steps of any method disclosed herein do not have to be performed in the exact order disclosed, unless explicitly stated.
As used herein, the term “comprising” and variations of that term are not intended to exclude other additives, components, integers or steps.
The gut with its microbiota has a key function to maintain immune homeostasis and approximately 70% of the immune system is estimated to be located in the gut.
Probiotics are defined as “a live microorganisms which, when administered in adequate amounts, confer a health benefit on the host” (FAO/WHO 2002).
Fibres are an essential part of our diet. Fibres can be divided into different groups and the group called soluble fibre are important for the gut microbiota. A group of the soluble fibres and oligosaccharides are called prebiotics.
Prebiotics are defined as “a substrate that is selectively utilized by host microorganisms conferring a health benefit” (International Scientific Association for Probiotics and Prebiotics 2017). When prebiotics are fermented in the gut, short chain fatty acids can be produced. Examples of the short chain fatty acids are acetic acid, butyric acid, propionic acid, and formic acid. It is known that short chain fay acids influence health, e.g. butyric acid nourishes the gut mucosa and propionic acid influences fat metabolism.
Synbiotics is defined as “an ingredient or dietary supplement combining probiotics and prebiotics for a synergy between the compounds”.
The combination of strains presented herein and used in the studies and experiments were carefully selected to be optimal combination of strains for efficacy including bacterial survival and favourable influence on each other.
Different combinations of bacterial strains and fibers may be used in a composition according to the present disclosure. Different combinations of bacterial strains and different combinations of fibers are described below. Specific combinations of bacterial strains and fibers are shown in Table 1. However, the following is not to be interpreted as excluding other combinations of bacterial strains and fibers.
Throughout the present disclosure, specific bacterial strains are identified by their deposition number.

Several different viruses may cause respiratory infections. Symptoms of such infections include fever, cough, sore throat, headache, fatigue, difficulties to breathe and/or reduced lung volume. A virus infection starts with the virus entering into the body and attaches to a virus receptor on the surface of cells in the respiratory tract. After attachment, the virus can enter into cells by different mechanisms and inside the cell the virus takes over the metabolism of the cell and multiplies.
Adenovirus, rhinovirus and coxsackievirus all belong to the group of naked viruses, i.e. they are not surrounded by a membrane. They attach to a receptor through the proteins on their surface.

Examples of areas where the microbiota has been shown to play an important role is on various immune functions including inflammation and on the gut-brain axis. The gut-brain axis is the bidirectional interaction between the gut and the central nervus system. Molecules of importance for this interaction are e.g. short chain fatty acids (SCFAs) which can be produced by the gut microbiota if a suitable substrate is available e.g. soluble fibres or oligosaccharides. The most abundant short chain fatty acids (SCFAs) in stool and body fluids are formic acid, acetic acid, propionic acid and butyric acid. SCFAs are multifunctional molecules, being e.g. an essential energy source for local intestinal cells, but also influencing barrier function, neurotransmitter release, microglial maturation and activation, neural proliferation, mitochondrial function, oxidative stress, immune-modulation, and anti-inflammatory processes. SCFAs can regulate brain function and behavior via a number of potential mechanisms and dysregulation of these pathways may contribute to autism and related disorders. Butyric acid, formic acid, acetic acid and propionic acid have previously been reported to have anti-inflammatory effects. SCFAs regulate several leukocyte functions including production of cytokines eicosanoids and chemokines. The ability of leukocytes to migrate to the foci of inflammation and to destroy microbial pathogens also seems to be affected by the SCFAs. Studies have shown that SCFA at physiological concentration may affect the pathogenesis of some viruses e.g. Herpesvirus at the epithelial site. The use of the SCFA butyrate or microbial metabolism for production of butyric acid has been speculated to be one way to support the treatment of SARS-CoV2-infection.
VCAM-1 (Vascular Cell Adhesion Molecule) is a receptor used by some types of Adenovirus during infection. VCAM-1 is a cell surface glycoprotein expressed on e.g. endothelial cells and immune cells such as macrophages and dendritic cells. VCAM-1 was originally identified as a cell adhesion molecule that helps to regulate inflammation-associated vascular adhesion and the transendothelial migration of leukocytes, such as macrophages and T cells. Recent evidence suggests that VCAM-1 is closely associated with the progression of various immunological disorders.
ICAM-1 (InterCellular Adhesion Molecule) is a receptor used by most Rhinoviruses and some Coxsackievirus as a receptor during infection. ICAM-1 is also important for the infection cycle of influenzavirus. ICAM-1 (also known as CD54 (Cluster of Difference 54)) is a cell surface glycoprotein that promotes signalling in between cells related to the immune response. ICAM-1 is expressed on endothelial cells, immune cells and on respiratory endothelium where it can serve as a receptor for viruses, e.g. human rhinovirus (HRV). Furthermore, patients suffering from a severe form of Covid-19 (caused by the coronavirus SARS-CoV-2) have markedly increased levels of ICAM-1. ICAM-1 is a receptor for 90% of all Rhinovirus. Studies have shown that Rhinovirus and some types of Adenovirus and Coxsackivirus share receptors. ICAM-1 has also been demonstrated to regulate the survival of influenzavirus in lung epithelial cells during the early stages of infection. Thus, reducing the expression of ICAM-1 is anticipated to have an effect on the clinical manifestation of virus infections, especially infections of the upper respiratory tract.
IL-12/IL23p40 has been identified as important in Inflammatory Bowel Disease (IBD), i.e. in ulcerative colitis and Crohn's disease, and is a target for medical treatment of the disease. Thus, reducing the expression of IL-12/IL-23p40 is anticipated to have an effect on the clinical manifestation of this disease.
In the experiments described below, the effect of a composition (corresponding to Composition No. 4) on the levels of i.a. IL-12/IL-23p40, ICAM-1, and SCFAs has been studied.
Immunological Markers and Short Chain Fatty Acids in Healthy Individuals and Individuals with Inflammation
The levels of selected immunological markers and short chain fatty acids were measured in blood samples from healthy individuals (n=57) and individuals diagnosed with inflammatory disorder/inflammatory load/inflammatory burden (n=154, 8-55 years old, both men and women). A variety of immune activity markers of which some also are virus receptors were analysed.
As can be seen in Table 2, individuals diagnosed with inflammatory disorder/inflammatory load/inflammatory burden have significantly (p<0.005) lower expression of IL-10 (an anti-inflammatory marker) and significantly (p<0.005) higher expression of the inflammatory markers and upper tract respiratory disease virus receptors sICAM-1 and sVCAM-1.
This clearly demonstrates that individuals with inflammatory disorder/inflammatory load/inflammatory burden express an inflammatory pattern of immune markers and express virus receptors at higher levels than healthy individuals.
Formic and propionic acids (short chain fatty acids) were lower in the individuals with inflammatory disorder/inflammatory load/inflammatory burden compared to the control group of 57 healthy individuals. Short chain fatty acids in plasma correlated positively with IL-10, i.e. individuals with a low level of short chain fatty acids also had a low level of the anti-inflammatory cytokine IL-10. This was seen both in children and in adults (data not shown).
Influence of a Synbiotic Composition According to the Present Disclosure on Inflammatory Markers and Virus Receptors in Individuals with Inflammation
A human intervention study was performed in a group of individuals (n=49, children, both boys and girls) diagnosed with inflammatory disorder/inflammatory load/inflammatory burden. The effect of a synbiotic composition according to the present disclosure on plasma levels of immune markers, virus receptors and short fatty acids in children diagnosed with inflammatory disorder/inflammatory load/inflammatory burden was investigated. The synbiotic composition included Lactobacillus plantarum LMG P-20606, Lactobacillus paracasei LMG P-17806, Pediococcus pentosaceus LMG P-20608 and the fibres inulin, pectin, resistant starch and beta-glucan. The total amount of bacteria was 4×1011 and the total amount of fibres was 10 g. The individuals diagnosed with inflammatory disorder/inflammatory load/inflammatory burden were randomized into one group (n=28) receiving the synbiotic composition according to the present disclosure and one group (n=21) receiving a maltodextrin placebo. The synbiotic composition according to the present disclosure was consumed once daily for nine weeks. Immune markers and virus receptors were analysed in plasma at start of the study (T=0) and after nine weeks of intervention (T=9).
After 9 weeks, children receiving the synbiotic composition according to the present disclosure had a significantly (p<0.05) reduced level of the inflammatory marker IL-12/IL-23p40, the upper tract respiratory disease virus receptor sICAM and of transforming growth factor β3 (TGF-β3) in plasma compared to the levels at start of the intervention study (Table 3).
The results clearly show that the synbiotic composition lowered the expression of IL-12/IL-23p40, sICAM and TGF-β3, which all are inflammatory marker. IL-12/IL-23p40 is a target for drugs against inflammatory diseases and ICAM also serves as a receptor for viruses. Thus, intake of the synbiotic composition according to the present disclosure lowers the level of an important receptor for viruses infecting the upper respiratory track, thus reducing the entry points of these viruses. Furthermore, the results show that the synbiotic composition lowers the expression of the pro-inflammatory molecules IL-12/IL-23p40, a target, the reduction of which is used in the treatment of ulcerative colitis and/or Crohn's disease. Thus, the synbiotic composition according to the present disclosure can be used in the alleviation or treatment of ulcerative colitis and/or Crohn's disease.
Influence of a Synbiotic Composition According to the Present Disclosure on Short Chain Fatty Acids and their Correlation to Inflammatory Markers and Virus Receptors
A human intervention study was performed in a group of individuals (n=49, children, both boys and girls) diagnosed with inflammatory disorder/inflammatory load/inflammatory burden as described above. The synbiotic composition increased the levels of propionic and acetic acid, which correlated negatively to the levels of sICAM-1 and sVCAM-1, i.e. the proinflammatory markers and receptors were high when the short chain fatty acid level was low (data not shown). Thus, treatment with the synbiotic composition according to the present disclosure is associated with lower vascular inflammation. The results clearly show that the level of short chain fatty acids is associated to the level of immune markers and receptors, and with low levels of short chain fatty acids associated to a pro-inflammatory pattern of the immune marker and an enhanced expression of the virus receptors. In the study it was also clear that the synbiotic composition increased the plasma level of short chain fatty acids which will stimulate a low inflammation.
A study was conducted in mice with the objective to demonstrate the effect of test products (different pre- and probiotics compositions according to the present disclosure) on intestinal inflammation induced by dextran sodium sulfate (DSS).
This study followed principles of Good Laboratory Practice (GLP) as defined by the Organization for Economic Co-operation and Development (OECD) as applicable. Procedures involving the care and the use of animals in the study was reviewed by the University of Lund Ethics Review Committee on Animal Experiments. During the study, the care and use of animals was conducted in accordance with the principles outlined in the current Guide to the Care and Use of Experimental Animals.
The study was conducted by the Dept Biology, Lund University.
Tested products were a combination of probiotic bacteria and prebiotic fibres:
Three control groups were run in parallel, one which was only run in parallel to the experiment but where the mice were not treated with anything, one given only 1% DSS in drinking water and no pro/prebiotics and one that was given 1% DSS and conventional treatment with mesalamine.
In all the groups, the ones given probiotics (i.e. Product 1, 2, 3 and 4 corresponding to composition 37, 56, 47 or 50) and the three control groups, twelve mice were included in each group. For initial testing of colon sensitivity, two groups of mice, one given no treatment and one given 1% DSS for 4 days, were used before gut sensitivity testing.
The daily dose of bacteria to a mouse was 2×10E8 CFU. The daily dose of fiber to a mouse was 0.0025 g/day.
Female and male mice of the line C57BL were used. The age of the animals was 10 weeks. Average weight of the animals was 20-25 g at the start. The mice were fed a standard commercial diet (Lactamin, Vadstena, Sweden) which was available ad libitum as was water. Animal body weight and feed intake after adaptation period was measured daily, and water intake measured weekly. All animals but the control group, without any treatment, was given 1% DSS to induce an inflammation in the gut. A schematic overview of the study timetable, its design and animals' randomization is given in
Blood samples were collected from the submandibular vein and isolated plasma was frozen at −80-C until analysis (plasma immunological profile).
Stool samples were collected both before starting the treatment as well as after DSS treatment and after product treatment. Stool samples were frozen until analysis of calprotectin using S100A8/A9 (MRP8/14, Calprotectin, Mouse/Rat) ELISA kit, KR6936, ImmunDiagnostik, Bensheim, Germany).
The study was finalized by all animals euthanized at the end of the study by treatment by an overdose of isoflurane/transcardial perfusion.
For post-mortem analysis and tissue sampling, half of the mice from each group was euthanized by isoflurane overdose. Spleen and colon were dissected from these mice and weighed and colon length was measured. Samples of large intestine (caecum, proximal and distal colon) were collected and fixed in 10% neutral formalin solution fixative for 24 hours for further morphological analysis.
The other half of the mice from each group was euthanized by transcardial perfusion with Thyrodes solution+LANA's Fixative. Caecum, proximal and distal colon was dissected from these mice. The intestinal samples were kept in the same fixative overnight and then transferred to 70% alcohol for further morphological analysis.
Mice colon hypersensitivity was assessed by measuring the threshold intensity of the abdominal withdrawal reflex (AWR) arising in response to colorectal distention. Distention was applied using an arterial embolectomy catheter (4F-Fogarty, Edwards Lifesciences LLC, Irvine, CA, USA) which was inserted rectally into the descending colon of anesthetized mice (2% isoflurane) and fixed at the base of the tail. AWR measurements were carried out 30 min after wake-up and reorientation of the animals. A visual observation of the reaction to the rapid phase stretching of the balloon for 20 s in ascending order (0.1, 0.25, 0.35, 0.5, and 0.65 ml) was carried out. The response of the animal to colorectal distention was assessed on an AWR scale: 0, no behavioral response; 1, brief movement of the head, followed by immobility; 2, contraction of abdominal muscles; 3, lifting the abdomen, and 4, body flexion and pelvic lift. The visceral pain threshold (VPT) was defined by the stimulus intensity whereby to evoke a visible contraction of the abdominal wall.
Morphological analysis was performed for three intestinal segments for six animals/group.
At dissection, samples were collected from the large intestine: caecum, proximal and distal colon, and fixed in 10% neutral formalin solution fixative for 24 hours. Next, tissue pieces were dehydrated and embedded in paraffin according to standard histological techniques. Paraffin-embedded tissues were sliced using rotor microtome into sections 4.5 microns (μm) thick. After overnight drying, slides were deparaffinized by incubation in xylene and decreasing concentrations of ethanol. Finally, standard hematoxylin and eosin staining was performed for morphology analysis.
Statistical analysis was performed as follows: The distribution of the parameters was checked using a Shapiro-Wilk normality test. One-way ANOVA or Kruskal-Wallis test corrected for multiple comparisons was used dependently on the data distribution. In all statistical analyses p s 0.05 was considered significant. All analyses were carried out using Prism, version 9.1.0 (GraphPad Software, Inc, San Diego, CA, USA).
Blood samples collected in EDTA tubes from the mice and plasma was collected. Selected biomarkers were analysed using Proximity Extension Assay (PEA) technology at Olink, Uppsala, Sweden. The technique combines immune technology with qPCR enabling a high-throughput, multiplex immunoassays of proteins using minimal volumes of serum, plasma, or almost any other type of biological sample. In total 75 different markers were analysed.
Plasma samples from all experimental groups were analysed with the PEA-technique.
To indicate colitis development and its severity in mice, clinical assessment of animals was performed daily. Clinical scores indicated the colitis development already at day 3 after 1% DSS introduction. Neither Mesalamine, which is approved by FDA for the treatment for IBD, nor the tested Products could influence body weight reduction. However, administration of Products 1, 2, and 3 led to significant (p<0,05) improvement in animals' wellbeing and general health status, including better stool consistency and faecal blood disappearance (Table 4a). The clinical score of mice from these groups (Products 1, 2, and 3) on the last day of study (Day 14) was significantly (p<0.05) lower than in the Placebo group and significantly lower than in the Mesalamine group i.e. when the mice were treated by a conventional treatment for IBD. Moreover, clinical score values observed in SB1 (Product 1) treated animals didn't differ from the those noted for healthy intact mice from Control group.
In conclusion: The Products 1, 2 and 3 (corresponding to Compositions No. 37, 56 and 47) led to a significant, 50-68%, improvement in health status in mice where IBD had been induced by 1% DSS (Table 4a). The effect seen from those three synbiotic products was also significantly better than when the conventional treatment with Mesalamine was used. This clearly indicates that compositions according to the present disclosure can be used in the prevention, amelioration, treatment, or reductions of symptoms in an individual suffering from IBD.
The well-established marker for IBD and gut inflammation calprotectin was analysed in faeces after 1% DSS treatment showing that already after 4 days of treatment there was a significant 3-5 fold increase in the marker (Table 4b). The conventional treatment by mesalamine did not reduce the effect of DSS, but treatment with Products 1 and 2 prevented further increment of caprotectin levels and Product 3 significantly reduced (P<0.05) fecal calprotectin by 49%.
In conclusion: Products 1 and 2 (corresponding to Compositions No. 37 and 56, respectively) prevented increment in calprotectin and Product 3 (corresponding to Composition No. 47) significantly reduced fecal calprotectin with 49%. This clearly indicates that compositions according to the present disclosure can be used in the prevention, amelioration, treatment, or reductions of symptoms in an individual suffering from IBD.
1% DSS-induced intestinal inflammation was characterized by inflammatory cell infiltration, abnormal crypt architecture, hyperplasia and edema. Some mild histological alterations were detected in the intact control group, however, all animals treated with DSS developed colitis. However, Mesalamine and Product 3 treatment significantly reduced inflammation, improved crypt structure and ameliorated edema by ca 50% (
In conclusion: Product 3 (corresponding to Composition No. 47) treatment significantly reduced inflammation, improved crypt structure and ameliorated edema by ca 50%. This clearly indicates that compositions according to the present disclosure can be used in the prevention, amelioration, treatment, or reductions of symptoms in an individual suffering from IBD.
The use of the synbiotic products significantly influenced several plasma biomarkers and in particular immunoactive markers. Three markers were influenced similarly independently of the product used.
In conclusion: The four synbiotic compositions influence three important immune markers in the same way or more as mesalamine, a substance established for the treatment of IBD. This indicates that the synbiotic compositions have a potential for treatment and/or alleviation of IBD. One of the synbiotic products (no 3 equivalent to composition 47) increased the amount of I110 in plasma. II 10 has important strong immune suppression properties which is important for treatment of inflammatory diseases such as IBD. This once again shows that the synbiotic composition can have an important role in treatment of IBD.
895 individuals (both men and women, from 18 years old) who had used a synbiotic composition according to the present disclosure (corresponding to Composition No. 19 in Table 1) for 1 week up to 2 years, sporadically up to every day, were questioned about their experiences and perceived effects of intake of the composition. The composition comprised Lactobacillus plantarum (LMG P-20606), Lactobacillus paracasei (LMG P-17806), Pediococcus pentosaceus (LMG P-20608), and Leuconostoc. mesenteroides (LMG P-20607) (total amount of of bacteria >1,5×1010 CFU/dose). Each dose further comprised inulin, pectin, resistant starch and betaglucan (total amount of fibers 3.75 g). Each individual independently reported any experienced positive effect(s) as well as any negative effects. None reported severe adverse effect or that medical treatment was needed. 504 individuals reported that one purpose of using synbiotic composition was “to strengthen the immune system”. 398 of these respondents had used the synbiotic composition daily or a couple of times per week. Out of these, 48 respondents had used the synbiotic composition 1-4 weeks. Responses to the question whether they felt that the synbiotic composition had helped them with problems with colds/seasonal flu are shown in Table 5a and in
Notably, already after 1-6 months, 28% of the respondents reported that they had less problems with colds/seasonal flu. After 1-2 years of regular intake, 45% of the respondents reported that they had less problems and after more than 2 years of regular intake, 53% reported less problems with colds/seasonal flu. The group “6-12 months” included only 46 individuals, i.e. the smallest group in this survey and considerably smaller than the groups “1-2 years” and “more than 2 years”. Thus, in this group, a single individual's response will contribute to a larger extent to the percentage of reported effect of the synbiotic composition. However, the groups “1-2 years” and “more than 2 years” are large groups, with 81 and 146 individuals respectively, and the reported results from these groups must be considered as representative of a larger population. In conclusion: The results demonstrate that a synbiotic composition according to the present disclosure reduces problems with colds/seasonal flu.
93 individuals (both men and women, from 18 years old) who had used a synbiotic composition according to the present disclosure (corresponding to Composition No. 19 in Table 1) for 4 weeks, sporadically up to every day, were questioned about their experiences and perceived effects of intake of the composition on effects concerning the gut/IBD and on infection and inflammation. The composition comprised Lactobacillus plantarum (LMG P-20606), Lactobacillus paracasei (LMG P-17806), Pediococcus pentosaceus (LMG P-20608), and Leuconostoc. mesenteroides (LMG P-20607) (total amount of of bacteria >1,5×1010 CFU/dose). Each dose further comprised 3,75 g of fibers (inulin, pectine, resistant starch and beta-glucan). Each individual independently reported any experienced positive effect(s) as well as any negative effects. None reported severe adverse effect or that medical treatment was needed. g
6 individuals reported that they suffered from IBD, e.g Crohn's disease, ulcerative colitis or other intestinal diseases. 4 of these respondents had used the synbiotic composition daily, almost every day or about half of the days. Responses to the question whether they felt that the synbiotic composition had helped them with problems related to the gastro intestinal tract (GI-tract) are shown in Table 5b.
As can be seen in Table 5b, already when the time period of regular intake of a synbiotic composition according to the present disclosure is as short as 4 weeks, the respondents report an improvement in symptoms related to IBD. In conclusion: the results indicate that a synbiotic composition according to the present disclosure may reduce problems with these symptoms and can be used in the treatment of IBD, including ulcerative colitis and Crohn's disease.
76 of the 93 respondents had used the synbiotic composition daily, almost every day or about half of the days. Responses to the question whether they felt that the synbiotic composition had helped them with problems related to the immune system and infections are shown in Table 5c.
As can be seen in Table 5c, already when the time period of regular intake of a synbiotic composition according to the present disclosure is as short as 4 weeks, respondents report an improvement in symptoms related to the immune system.
In conclusion: the results indicate that a synbiotic composition according to the present disclosure may reduce problems with these symptoms and can be used in the treatment and/or prevention of infections, such as viral infections.
Effect of a Composition According to the Present Disclosure on Persons with Symptoms Lasting Longer than 2 Months after Covid 19 Infection
Otherwise healthy persons (male) who had experience symptoms of fatigue, smell or taste loss or other symptoms that could be related to Post Covid more than 2 month after a Covid 19 infection. The Covid 19 infection had been confirmed with PCR or antigen testing.
The composition (corresponding to Composition No. 19 in Table 1) comprised Lactobacillus plantarum (LMG P-20606), Lactobacillus paracasei (LMG P-17806), Pediococcus pentosaceus (LMG P-20608), and Leuconostoc. mesenteroides (LMG P-20607) (total amount of bacteria was 4×1010 CFU/dose).
