Post-infectious irritable bowel syndrome — one of the most frequent conditions diagnosed in pediatric gastroenterological practice. According to numerous research parisitosis contributes to the chronology of gastrointestinal tract pathology. it is known that the infection Lamblia intestinalis can increase the risk of developing post-infectious IBS, changing species composition and diversity of the intestinal microbiota, modulating metabolism of the host, the nature of the immune response and adversely affecting the mucosal barrier and the motility of the digestive tract. Importantly, the prevalence of giardiasis in patients with symptoms of IBS and dyspepsia at the moment, it remains at a high level. Further research into the pathogenesis of Lamblia intestinalis infection in patients with IBS will be of great importance in medicine.

Irritable Bowel

Irritable bowel syndrome (IBS) is a chronic functional disorder of the gastrointestinal tract and is one of the most frequent gastrointestinal diseases. In IBS multiple pathophysiological mechanisms including alterations in intestinal motility, permeability, nutrient absorption, and intestinal microbiota have been implicated. Foods are commonly reported by patients to be a trigger of symptoms and therefore are likely involved in the generation of symptoms in IBS. Among all possible therapeutic options, a first-line approach to IBS is dietary education and identification of foods potentially responsible for the onset or worsening of symptoms. Dietary approaches include reduction of gas-producing foods (i.e. fermentable oligo-, di-, and monosaccharides and polyols (FODMAPs)), lactose and gluten. Further studies are required to link the ultimate role of diets in different IBS subtypes.

Introduction: Rotavirus infection (RVI) is one of the most common childhood illnesses in countries where routine vaccination against the disease isn`t introduced. The incidence of RVI in Russia remains at a consistently high level, leading to a huge socio-economic damage. In addition, in children who have undergone severe forms of the disease, have high risk of post-infectious functional disorders of the gastrointestinal tract (FD), leading to a decrease in the quality of life and prolonged persistence of dyspeptic phenomena. The pathogenetic mechanisms and factors predisposing to FD in RVI convalescents remain insufficiently studied.The aim of the study was to establish the possible role of intestinal microbiocenosis disorders and immune response in the formation of gastroenterological pathology in children, convalescents of RVI.Material and methods: The work was performed in 2014- 2019. in Pediatric Research and Clinical Center for Infectious Diseases. In the course of the implementation, a comprehensive clinical and laboratory examination was carried out for 60 children aged 1 to 7 years who had suffered RVI in a severe or moderate form, since the onset of infection followed by a three-year follow-up observation. Particular attention was paid to the assessment of intestinal microbiocenosis and immune response in the study group of patients. The interpretation of dyspeptic symptoms in the follow-up period was carried out on the basis of the Rome IV revision criteria. The structure of gastrointestinal tract disorders after rotavirus infection has been established.Results: It was shown that with RVI, persistent changes in the intestinal microbiota are observed, characterized by a decrease in the number of symbiotic Bacteroides thetaiataomicron, Lactobacillus spp. and Faecalibacterium prausnitzii and overgrowth of semipathogenius microorganisms, including Bacteroides fragilis.Conclusion: A close relationship of a number of factors (a decrease in the level of virus-induced production of IFNγ and serum IgA, overgrowth of Proteus spp., Bacteroides fragilis and a decrease in the level of Faecalibacterium prausnitzii and Bacteroides thetaiotaomicron) with the formation of FD in the follow-up period was revealed.

The Moment

Irritable bowel syndrome is a frequent digestive condition, with an unclear etiopathogeny. Very probably intestinal dysbiosis plays an important role. For the moment there are no guidelines for treatment. There is scientific evidence for several therapies: modification of diet, non-resorbable antibiotics (rifaximin-α) and probiotics. Giving probiotics after each antibiotic course (an association of Bifidobacterium longum BB536 and Lactobacillus rhamnosus HN001) supplemented with vitamin B6 may be an optimal strategy.

Irritable Bowel Syndrome (IBS) is a chronic functional gastrointestinal disorder characterized by abdominal pain associated with defecation or a change in bowel habits. Gut microbiota, which acts as a real organ with well-defined functions, is in a mutualistic relationship with the host, harvesting additional energy and nutrients from the diet and protecting the host from pathogens; specific alterations in its composition seem to play a crucial role in IBS pathophysiology. It is well known that diet can significantly modulate the intestinal microbiota profile but it is less known how different nutritional approach effective in IBS patients, such as the low-FODMAP diet, could be responsible of intestinal microbiota changes, thus influencing the presence of gastrointestinal (GI) symptoms. The aim of this review was to explore the effects of different nutritional protocols (e.g., traditional nutritional advice, low-FODMAP diet, gluten-free diet, etc.) on IBS-D symptoms and on intestinal microbiota variations in both IBS-D patients and healthy subjects. To date, an ideal nutritional protocol does not exist for IBS-D patients but it seems crucial to consider the effect of the different nutritional approaches on the intestinal microbiota composition to better define an efficient strategy to manage this functional disorder.
