Description

[0001] COMBINATION OF PROPOLIS AND PROBIOTICS TO PREVENT AND / OR FIGHT CHRONIC INFLAMMATORY BOWEL DISEASES (IBD)

[0002] Technical field

[0003] The invention relates to the technical field of prevention and / or control of chronic inflammatory bowel diseases (IBD). In particular, the invention relates to a particular composition (a) combining propolis with at least one probiotic strain, its method of production and its uses.

[0004] State of the art

[0005] Inflammatory bowel diseases, also known as IBD, are a group of complex and debilitating conditions that primarily include Crohn's disease and ulcerative colitis.

[0006] These conditions are characterized by inflammation of the wall of a part of the digestive tract, caused by deregulation of the intestinal immune system. This uncontrolled immune response is mediated by the release of pro-inflammatory molecules, mainly cytokines, which disrupt the permeability of the intestinal wall.

[0007] As a result, the natural barrier function of the intestinal wall is impaired, leading to increased permeability. This impairment allows normally filtered pathogens to enter intestinal cells, triggering inflammatory reactions in other organs.

[0008] This uncontrolled inflammation leads to tissue damage and a chronic course of the disease.

[0009] The origins of these conditions appear to result from a complex combination of environmental factors, patients' specific genetic susceptibility and the particular reactivity of their immune system.

[0010] IBD causes often debilitating symptoms, such as abdominal pain, frequent diarrhea, weight loss, and a significant impairment in quality of life. Patients with IBD face daily challenges and require ongoing medical management to control their intestinal inflammation and relieve their symptoms. Current treatments for IBD primarily aim to reduce inflammation and relieve patients' symptoms. One of the most commonly used treatments is 5-aminosalicylate (5-ASA) in combination with a TNF blocker. However, these treatments have notable drawbacks. For example, anti-inflammatory drugs can cause unwanted side effects, such as gastric ulcers and an increased risk of infections.

[0011] Immunosuppressants, on the other hand, weaken the immune system, making patients more vulnerable to opportunistic infections. Biological therapies, while effective, are often expensive and require regular and sometimes invasive administration, which can be a burden for patients. Furthermore, some patients with ICI do not respond to any existing treatment.

[0012] Given the limitations of existing treatments, it is essential to continue research to develop new therapeutic approaches for IBD, particularly based on natural treatments.

[0013] There is therefore a need for a new alternative treatment aimed at preventing and / or combating intestinal inflammation, more particularly preventing and / or combating chronic inflammatory bowel diseases, and, consequently, improving the quality of life of those suffering from these pathologies.

[0014] Summary of the invention

[0015] To meet this need, the invention proposes a new composition (a) comprising propolis and at least one strain of probiotic.

[0016] Propolis is a resinous, gummy, and balsamic substance produced by bees. It is the result of mixing bees' wax and salivary secretions with substances collected from the bark and buds of plants or trees, such as poplar, birch, willow, spruce, fir, baccharis, or dalbergia.

[0017] Propolis is composed of a broad spectrum of polyphenols such as phenolic acids and flavonoids, which confer therapeutic properties, including antibacterial, antiviral, antifungal, and anti-inflammatory properties. A probiotic strain is a strain of live microorganism, usually a bacterium or yeast, that exhibits beneficial effects on the health of the host when consumed in adequate amounts. Probiotic strains are specific and identified by their precise taxonomic classification. They are carefully selected due to their particular characteristics, such as their ability to survive in the gastrointestinal tract, their adherence to epithelial cells, their resistance to gastric and bile acids, and their ability to modulate the composition and activity of the gut microbiota.

[0018] Probiotics work by colonizing the gastrointestinal tract, where they interact with existing flora and intestinal epithelial cells. They can exert various beneficial effects, such as competing with pathogenic microorganisms, stimulating the immune system, producing beneficial metabolites, degrading dietary fiber, and regulating inflammation.

[0019] Surprisingly, the inventors discovered that the combination of propolis and at least one strain of probiotic allowed to obtain an improved effect on the reduction of intestinal inflammation, thus making it possible to reduce the symptoms linked to IBD, preferentially to treat IBD.

[0020] Preferably, composition (a) according to the invention comprises at least one propolis chosen from poplar propolis, baccharis propolis, dalbergia propolis and mixtures thereof.

[0021] Preferably, composition (a) according to the invention comprises propolis comprising at least 10% of total polyphenols relative to the weight of the propolis, even more preferably at least 15%.

[0022] Advantageously, the high concentration and diversity of polyphenols within propolis allows for an improved effect with at least one probiotic strain on intestinal inflammation.

[0023] According to a preferred subject, the composition (a) according to the invention comprises at least one strain of probiotic chosen from Lactobacillus Paracasei, Lactobacillus Plantarum, Lactobacillus rhamnosus, Lactobacillus helveticus, Bifidobacterium lactis, Bacillus subtilis and Enterococcus faecium.

[0024] Advantageously, these probiotic strains are individually already known to have an effect on reducing intestinal inflammation. Preferably, the composition (a) according to the invention comprises at least 10 7 CFU / g of composition (a) of at least one probiotic strain.

[0025] According to another preferred subject, the composition (a) according to the invention also comprises at least one prebiotic.

[0026] A prebiotic is an indigestible substance found in certain foods, primarily dietary fiber, that promotes the growth and activity of beneficial bacteria in our digestive system, called probiotics. Unlike probiotics, which are live microorganisms, prebiotics are food substrates that selectively feed probiotics and help them thrive.

[0027] When combined, probiotics and prebiotics work together to enhance the beneficial effects on the gut microbiota. Prebiotics provide a preferential food source for probiotics, helping them survive and multiply in the gut. In turn, probiotics enhance their beneficial effects through the stimulation provided by prebiotics.

[0028] According to another aspect, the invention relates to a process for preparing a composition (a) according to the invention comprising the implementation of the following steps:

[0029] (1)Preparation of propolis;

[0030] (2)Preparation of at least one probiotic strain; and

[0031] (3) Mixture of propolis from step (1) and at least one probiotic strain selected in step (2).

[0032] Finally, according to a last aspect, the invention relates to the composition (a) according to the invention for its use as a food supplement or medical device in humans or animals.

[0033] Preferably, composition (a) according to the invention can be used to prevent and / or combat intestinal inflammation, even more preferably to prevent and / or combat M ICI.

[0034] Other characteristics and advantages will emerge from the detailed description of the invention, examples and figures which are solely illustrative and in no way limit the scope of the invention.

[0035] Brief description of the figures: [Fig 1] Figure 1 is a graphical representation demonstrating the improved effect of composition (a) comprising the combination of propolis and at least one probiotic strain on the inhibition of TNF-alpha, a pro-inflammatory cytokine.

[0036] [Fig 2] Figure 2 is a graphical representation demonstrating the enhanced effect of composition (b) comprising the combination of artepillin C and at least one probiotic strain on the inhibition of TNF-alpha, a pro-inflammatory cytokine.

[0191] According to one variant, the composition (a) according to the invention can be used as a medical device. Surprisingly, the inventors discovered that the combination of propolis with at least one strain of probiotic made it possible to provide a natural alternative to existing drugs, in particular drugs aimed at reducing intestinal inflammation, such as 5-aminosalicylic acid (5-ASA).

[0192] According to a preferred embodiment, the composition (a) according to the invention can be used to prevent and / or combat chronic inflammatory bowel diseases (IBD).

[0193] Preferably, composition (a) according to the invention can be used to prevent and / or combat intestinal inflammation.

[0194] The surprising combination of propolis with at least one probiotic strain has an improved effect on reducing intestinal inflammation. Thus, composition (a) according to any of the embodiments described above can be used to prevent and / or combat intestinal inflammation. Composition (a) can thus be used to improve the quality of life and / or relieve people suffering from intestinal inflammation.

[0195] Advantageously, the association between propolis and at least one strain of probiotic makes it possible to prevent and / or combat a large number of intestinal conditions and more particularly diseases or disorders associated with intestinal inflammation.

[0196] Diseases or disorders associated with intestinal inflammation include, in particular, the following pathologies:

[0197] * Inflammatory bowel disease (IBD): This term includes Crohn's disease and ulcerative colitis, but it is also used to refer to other, less common forms of inflammatory colitis, such as microscopic colitis and indeterminate colitis. IBD is characterized by chronic inflammation of the intestine, leading to symptoms such as abdominal pain, diarrhea, weight loss, and rectal bleeding.

[0198] *Crohn's disease: This is a chronic inflammatory bowel disease that can affect any part of the digestive tract, from the mouth to the anus. Crohn's disease causes inflammation of the intestinal wall, leading to symptoms such as abdominal pain, diarrhea, weight loss, fatigue, and rectal bleeding. *Ulcerative colitis: Also known as ulcerative colitis, this is a chronic inflammatory disease that primarily affects the colon and rectum. It is characterized by ulcers and inflammation of the intestinal lining, leading to symptoms such as abdominal cramps, bloody diarrhea, weight loss, and fatigue.

[0199] *Irritable bowel syndrome (IBS): IBS is a functional disorder of the digestive system that causes abdominal pain, bloating, bowel movements (diarrhea or constipation), and changes in stool consistency. Although the exact cause of IBS is not clearly understood, intestinal inflammation and immune system dysfunction may play a role.

[0200] *Celiac disease: This is an autoimmune disease in which the immune system reacts abnormally to the presence of gluten, a protein found in wheat, barley, and rye. Ingestion of gluten causes inflammation of the intestinal lining in people with celiac disease, leading to symptoms such as abdominal pain, diarrhea, weight loss, and digestive problems.

[0201] * Indeterminate inflammatory bowel disease (IBD): Some people may have symptoms and signs of intestinal inflammation, but do not meet the specific criteria for Crohn's disease or ulcerative colitis. These cases are then classified as indeterminate IBD.

[0202] * Post-infectious irritable bowel syndrome (PIPS): PIPS develops after an intestinal infection, usually bacterial or viral gastroenteritis. It is characterized by symptoms similar to those of irritable bowel syndrome, such as abdominal pain, changes in bowel habits, and bloating, which persist for weeks or even months after infection.

[0203] * Diverticulosis and diverticulitis: Diverticulosis is a condition where small pouches (diverticula) form in the wall of the colon. When these diverticula become inflamed or infected, it causes a condition called diverticulitis. Diverticulitis leads to inflammation of the colon, causing abdominal pain, fever, bowel movements, and bleeding.

[0204] *Short bowel syndrome: This syndrome occurs when large portions of the intestine are surgically removed, usually due to disease or injury. It can lead to residual inflammation in the remaining parts of the intestine, as well as problems with nutrient absorption, causing chronic diarrhea, malnutrition, and electrolyte imbalances.

[0205] *Autoimmune diseases with intestinal involvement: Some autoimmune diseases, such as systemic lupus erythematosus and rheumatoid arthritis, can also lead to inflammation of the intestine. These diseases affect the immune system and can cause inflammation in different parts of the body, including the intestine.

[0206] * Drug-induced intestinal inflammation: Certain medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, and oral contraceptives, can cause inflammation of the intestinal lining in some susceptible individuals. This can lead to gastrointestinal symptoms such as abdominal pain, diarrhea, and ulceration.

[0207] * Parkinson's disease: Parkinson's disease is a neurodegenerative disorder characterized by a decrease in dopamine in the brain, resulting in symptoms such as tremors, muscle rigidity, and coordination problems. Recent studies suggest a link between Parkinson's disease and intestinal inflammation. Chronic inflammation in the gut can trigger an inflammatory response in the brain, contributing to the development or progression of Parkinson's disease.

[0208] * Alzheimer's disease: Alzheimer's disease is the most common form of dementia. It is characterized by the progressive loss of memory and cognitive function. Recent research has also highlighted a link between Alzheimer's disease and intestinal inflammation. Chronic inflammation of the intestine can promote the production of amyloid peptides, abnormal substances that accumulate in the brain and play a key role in the development of Alzheimer's disease.

[0209] * Autism: Autism is a developmental disorder that affects communication, social interactions, and behavior. Although the precise mechanisms of autism are not yet fully understood, recent studies have shown a link between autism and intestinal inflammation. Alterations in the composition of the intestinal flora, as well as elevated inflammatory markers in the gut, have been observed in many individuals with autism. * Diseases associated with dysbiosis: Dysbiosis refers to an imbalance in the intestinal flora, where beneficial bacteria are reduced and harmful bacteria are favored. This imbalance can lead to various diseases, including certain inflammatory bowel diseases.

[0210] * SIBO (Small Intestinal Bacterial Overgrowth): SIBO is a condition in which there is an excessive growth of bacteria in the small intestine. This condition can lead to intestinal inflammation and symptoms such as bloating, abdominal pain, and digestive problems.

[0438] Example 1: Measurement of the effect of composition (a) and composition (b) according to the invention on the reduction of intestinal inflammation

[0439] Cell culture and treatments:

[0440] Caco-2 intestinal cells were cultured in MEM supplemented with 10% fetal bovine serum, 1% antibiotics (penicillin 100 IU / ml and streptomycin 50 pg / ml), L-Glu and incubated at 37 °C in a humidified chamber containing 5% CO2.

[0441] Then, the cells were cultured at a density of 50 x 103 cells per well for 21 days until their differentiation. The integrity of the monolayer was assessed daily by microscopic visualization.

[0442] After their differentiation, Caco-2 cells were pretreated with: * crude Baccharis propolis at 2.5 or 5 pg / ml;

[0443] * a mixture of Lactobacillus Paracasei and Lactobacillus Plantarum in a ratio of 1:1 at concentrations of 106 and 107 CFU / mL.

[0444] *Artepi lline C at 2.5 and 7.5 pM; and

[0445] * their combinations.

[0446] The results are shown in Figure 1 and Figure 2.

[0447] The Baccharis propolis used in this example is obtained by cold grinding of raw propolis.

[0448] The Lactobacillus Plantarum strain used in this example is referenced I- 5597 (CNCM) and the Lactobacillus Paracasei strain is referenced LMG S-25516 (BCCM)

[0449] To induce an inflammatory state, Caco-2 cells were then treated with LPS at a concentration of 0.5 pg / ml for 4 hours. N-acetyl-5-Aminosalicylic acid (5-ASA) was used as a control against the inflammatory state. After LPS treatment, supernatants were collected (volume of 250 pL) and stored at -80 °C until further analyses.

[0450] Cytokine Measurement and Statistical Analysis

[0451] 1) Absolute TNF-alpha levels

[0452] Human TNF-alpha level was assayed using an ELISA kit according to the manufacturer's instructions.

[0453] 2) Relative levels of cytokines

[0454] Cytokine levels were normalized and expressed as % of levels obtained with LPS alone.

[0455] 3) Statistical analysis

[0456] Statistical analyses were performed using Sigma Plot software. Different tests can be performed depending on the data: ANOVA followed by Dunnet's test, if the application conditions are met.

[0457] The results presented in Figure 1 show that the crude extract of Baccharis propolis exerts an inhibitory activity on the production of a pro-inflammatory cytokine in Caco-2 intestinal cells. Both probiotic strains (L.Paracasei as well as L / Plantarum) also showed an anti-inflammatory effect. Finally, the combination of Baccharis propolis and the two probiotic strains showed an improved effect on the inhibition of the production of pro-inflammatory cytokines, more particularly on the production of TNF-alpha.

[0458] The results presented in Figure 2 show that Artepillin C exerts an inhibitory activity on the production of a pro-inflammatory cytokine in Caco-2 intestinal cells. Both probiotic strains (L.Paracasei as well as L / Plantarum) also showed an anti-inflammatory effect.

[0459] Finally, the combination of Artepi I line C and the two probiotic strains showed an improved effect on the inhibition of the production of pro-inflammatory cytokines, more particularly on the production of TNF-alpha.
