[Effect of 6-month S-methylmethionine intake on the quality of life and dyspepsia symptoms in patients with chronic gastritis].

S-methylmethionine (methylmethionine sulfonium chloride), better known as vitamin U, is a metabolic substrate that affects many metabolic processes in the human organism. Since its discovery, a large number of studies has been produced demonstrating its safety and effectiveness in various diseases, especially in diseases of the gastrointestinal tract. The purpose of the study was to evaluate the effect of methylmethionine sulfonium chloride (vitamin U) intake on the symptoms of dyspepsia and the quality of life of patients with chronic gastritis. Material and methods. The study included 37 patients (21 men and 16 women) aged 35-60 years with chronic gastritis of various etiologies. After inclusion in the study, all patients were prescribed S-methylmethionine at a dose of 300 mg per day. Clinical manifestations of dyspepsia were assessed using the GSRS questionnaire (Gastrointestinal Symptom Rating Scale), quality of life was assessed using the SF 36 questionnaire. The survey was conducted before the start of the therapy, after 3 and 6 months of complex diet therapy. Results. The most pronounced manifestations were dyspeptic (from 3 to 9 points) and diarrheal syndromes (from 2 to 5 points). Other indicators of the GSRS scale did not exceed 4 points. The total score was 15 points. By the 3rd month of therapy, there was a statistically significant decrease in the total score to 9 points (p<0.05). By the 6th month of therapy, the total GSRS score averaged 5.5 points (p<0.05). According to the SF 36 questionnaire, by the end of the 3rd month of therapy, indicators such as PF - physical functioning, BP - Bodily pain and SF - social functioning improved. By the end of the 6th month of therapy, several other indicators also improved (RP - role-physical functioning, GH - general perception of health, VT - viability, RE - Role-Emotional; MH - mental health) (p<0.05). Conclusion. The study showed that the appointment of dietary supplements containing methylmethionine sulfonium chloride at a dose of 300 mg per day helps to reduce the severity of dyspeptic symptoms in patients with chronic gastritis and their quality of life.

[Prospects of probiotic strains of bifidobacteria and enterococcus in treatment and prevention of diseases in gastroenterology].

Variability of the intestinal microbiota has been under close scientific study in recent years; more and more studies confirm specific changes in microbiota under certain pathologies. Enterococcus faecium and Bifidobacterium longum strains are naturally occurring symbiotic bacteria that inhabit the gastrointestinal tract. The safety and efficacy profile of bifidobacteria, widely used as probiotics, has been thoroughly studied. Deviations in species composition, diversity, and relative abundance have been reported for some diseases. The aim of the research was to substantiate the need and to study the prospects for the inclusion of probiotics strains of bifidobacteria and enterococci in the complex therapy of gastroenterological diseases. Material and methods. The data from MEDLINE and PubMed-NCBI bibliographic databases have been analyzed in this review. Results and discussion. The published data indicate the positive effect of bifidobacteria on human health, starting from a direct effect inside the gastrointestinal tract, moving to modulating the immune system and, in general, the systemic effect of probiotics on the organism by changing the level of various mediators. Probiotic strains of Enterococcus faecium contribute to the preservation and growth of endogenous species of bifidobacteria and lactobacilli. Additional intake, as well as stimulation of the growth and activity of probiotic strains in the intestine can be considered as a potential approach to combating foodborne intestinal pathogens, to the treatment of lactase deficiency and irritable bowel syndrome. Conclusion. The inclusion of probiotics in the complex therapy of lactase deficiency, irritable bowel syndrome, as well as antibiotic-associated diarrhea is pathogenetically substantiated.

[Clinical efficacy of probiotic strains of the Bifidobacterium and Lactobacillus].

The article analyzes the effectiveness of the most studied probiotic strains that are used for prophylactic or therapeutic purposes. The requirements for probiotic microorganisms are described, depending on the form in which they are used. However, their scope most often covers both prevention and treatment of various functional disorders and diseases of the gastrointestinal tract. At the same time, a lot of data has been accumulated on the effectiveness of probiotics for the treatment and prevention of diseases of other organs and organism systems. Most strains are successfully used as dietary supplements, and some of them have found their application in food industry.
