[Clinical efficacy of a modern probiotic for the correction of intestinal microflora in patients with irritable bowel syndrome with diarrhea and antibiotic-associated diarrhea].

Despite the fact that dietary supplements (DS) are not medicines, an increasing number of publications testify to the effectiveness of probiotics consumed with food in the complex treatment and prevention of a number of diseases of the gastrointestinal tract, including irritable bowel syndrome (IBS) and antibiotic-associated diarrhea (AAD). of the study was to evaluate the effectiveness of the complex probiotic in the relief of diarrheal syndrome associated with intestinal microbiota dysbiosis in patients with IBS with diarrhea and AAD. . The study included 54 patients (31 with IBS with diarrhea and 23 with idiopathic AAD) aged 18 to 50 years. All patients included in the study were prescribed 1 capsule (350 mg) of the DS Neobiotic Lactobalance® per day for 21 days. One capsule contains: bifidobacteria (Bifidobacterium longum CBT BG7, Bifidobacterium lactis CBT BL3 Bifidobacterium bifidum CBT BF3), lactobacilli (Lactobacillus acidophilus CBT LA1, Lactobacillus rhamnosus CBT LR5), lactic acid bacteria (Streptococcus thermophilus CBT ST3), fructooligosaccharides, vitamin C. The daily intake of bifidobacteria was 8.7×10 CFU, lactobacilli - 6.1×10 CFU, lactic acid bacteria 3.1×10 CFU and vitamin C - 12 mg. The severity of symptoms was assessed in points (from 0 to 7 points) using the GSRS questionnaire (Gastrointestinal Symptom Rating Scale). All patients underwent a microbiological analysis of feces with an assessment of the degree of dysbiosis before and after the administration of DS. . In patients with IBS with diarrhea, the assessment of the manifestations of diarrheal syndrome according to the GSRS questionnaire decreased statistically significantly from 17 to 6 points (2.9 times), abdominal pain - from 12 to 4 points (3.0 times) and dyspeptic syndrome - from 8 to 3 points (in 2.7 times). In patients with AAD, also according to the GSRS questionnaire, the manifestations of diarrheal syndrome decreased statistically significantly from 13 to 3 points (4.3 times), abdominal pain - from 4 to 1 points (4.0 times) and dyspepsia syndrome - from 5 to 2 points (in 2.5 times). Against the background of DS intake, according to the data of bacteriological examination of feces, intestinal microbiota normalized by day 21 due to an increase in the number of lacto- and bifidobacteria (p=<0.05). . The study showed that the DS Neobiotic Lactobalance® contributes to the normalization of the intestinal microbiota and reduces the severity of clinical manifestations (diarrheal disorders or manifestations of diarrhea) in IBS and idiopathic AAD.
