The bacterial overgrowth syndrome in the small intestine and gastrointestinal symptoms in patients with inflammatory bowel diseases depending on the presence of smal-intestinal bacterial overgrowth syndrome

Abstract

Research objective: to study the frequency of gastrointestinal symptoms in patients with inflammatory bowel disease (IBD) depending on the presence of the small intestinal bacterial overgrowth (SIBO). Materials and methods of the study: The study included 152 patients with IBD. All patients would be given a hydrogen breath test (VDT) with lactulose to diagnose SIBO. The analysis of gastrointestinal symptoms in patients depending on the presence of SIBO, as well as the dynamics of symptoms after its correction was carried out. Results: The frequency of SIBO in patients with IBD was 48%. Patients with SIBO were more likely to have symptoms: diarrhea, bloating, flatulence, weakness, whining and irritability. After a 2-week course of correction of SIBO, patients had a decrease in the frequency of these symptoms. Conclusion: The data obtained indicate a high frequency of SIBO in patients with IBD. SIBO is associated with symptoms that may accompany an acute attack of the IBD. The diagnosis of SIBO should be included in routine practice in patients with acute attack of IBD for selection of adequate therapy, which will include correction of microbiota disorders and will not lead to inappropriate change of basic therapy.
