Abstract
Post-infectious irritable bowel syndrome (PI–IBS) is the first phenotype of the disease described in the literature and the most studied to date. The prevalence of PI–IBS in the population continues to grow steadily especially in the post-COVID-19 pandemic period. Taking into account the accumulated scientific and clinical data dysfunction of the functional axis «microbiota-gut-brain» associated with the formation of visceral hypersensitivity and intestinal motor disorders due to abnormal serotonin metabolism, increased intestinal permeability and low-grade inflammation is considered as a key pathogenetic factor underlying the development and persistence of PI–IBS symptoms. This review article analyzes and summarizes information on the mechanisms of PI–IBS associated with changes in neurohumoral regulation, as well as the qualitative and quantitative composition of the intestinal microbiota. In addition, data on the possibility of using probiotic therapy in the complex therapy of patients with PI–IBS are presented.
