[The effectiveness of a probiotic containing Bifidobacterium longum BB-46 and Enterococcus faecium ENCfa-68 in the treatment of post-infectious irritable bowel syndrome. Prospective randomized comparative study].

BACKGROUND: In the treatment of post-infectious irritable bowel syndrome (PI-IBS), the leading role belongs to the normalization of the composition of the intestinal microbiome, the disturbances of which are associated with previous intestinal infections. AIM: To study the effectiveness of the drug Bifiform in the treatment of PI-IBS. MATERIALS AND METHODS: An open, prospective, comparative, randomized study included 62 patients with PI-IBS. The diagnosis was confirmed by the results of clinical, laboratory and endoscopic examination of the intestine and met the diagnostic criteria for IBS of the Rome Consensus IV. The patients were randomized into 2 groups depending on the therapy. The patients of the main group received an antispasmodic drug (mebeverin 200 mg 2 times a day or trimebutin 200 mg 3 times a day for 4 weeks), an antibiotic (rifaximin 400 mg 3 times a day or nifuroxazide 400 mg 2 once a day for 1 week), a drug that normalizes the consistency of feces (dioctahedral smectite or macrogol 4000) and Bifiform 2 capsules 2 times a day for 2 weeks. For patients of control group similar therapy was performed without the Bifiform. Evaluation of the effectiveness of treatment was carried out at the end of the course of therapy and 6 months after its termination. RESULTS: All included patients with PI-IBS had abdominal pain, flatulence and tenderness to palpation along the bowel, most of them had diarrhea. Disorders of the intestinal microbiota were detected in 77.4% of patients, while excessive bacterial growth in the small intestine occurred in 72.6%, disorders of the colon microbiocenosis with the presence of opportunistic bacteria in 62.9% of patients. A significant part of the patients had a combination of small and large intestinal dysbiosis. Histological examination of the colon mucosa showed signs of low degree of inflammation activity in all patients. The moderate increase in the level of fecal calprotectin was found in 62.2% of patients with colonic dysbiosis. The majority of patients in the main group showed a pronounced positive dynamics of clinical manifestations of the disease, restoration of the normal composition of the intestinal microbiota and normalization of the content of fecal calprotectin at the end of the course therapy. The good result was observed much more often in the main group at the end of the course of treatment and 6 months after its termination. CONCLUSION: The inclusion of Bifiform in the complex therapy of PI-IBS significantly increases its effectiveness both in arresting the clinical manifestations of the disease, and in restoring the normal composition of the intestinal microbiome and reducing the inflammatory process in the intestinal mucosa. In the majority of patients receiving Bifiform, the remission of the disease achieved at the end of the course of treatment and persisted even 6 months after its termination.

[The cytoprotective drug rebamipide in therapy for inflammatory and erosive-ulcerative lesions of the gastrointestinal tract]. / Tsitoprotektor rebamipid v terapii vospalitel'nykh i erozivno-yazvennykh porazhenii zheludochno-kishechnogo trakta.

Rebamipide is a cytoprotесtive drug that stimulates the generation of endogenous prostaglandins in the gastric and small intestinal mucosa and accelerates the healing of erosions and ulcers caused by Helicobacter pylori infection and NSAID administration. The major properties of rebamipide include stimulation of prostaglandins and synthesis of muсus glycoproteins, inhibition of reactive oxygen species, inflammatory cytokines, and chemokines, and suppression of neutrophil activation. This paper shows the ability of rebamipide to enhance the efficiency of therapy for Helicobacter pylori-induced infection, to reduce inflammation, including that after infection eradication, to accelerate ulcer healing, and to prevent the progression of preneoplastic lesions.
