Inflammatory bowel diseases are an urgent public health problem and are often complicated by the development of anemic syndrome. Significant progress has been made in the treatment of ulcerative colitis and Crohn's disease, but the correction of associated anemia in most cases remains insufficient. This article describes in detail the pathogenetic mechanisms of the formation of anemic syndrome in inflammatory bowel diseases, as well as possible ways to correct this condition.

Aim of review. The review highlights modern concepts of the role of microbiome in sustaining the human body, the place of probiotics in treatment and prevention of pathologies related to disorders in healthy microbiota.Key points. Microbiome is a unique panorganismal system normally maintaining self-equilibrium and possessing a vast and diverse functionality. Imbalance in normal microbiota can be assisted by probiotics, i.e. living microorganisms that sustain health of the host when being supplied in adequate amounts. Alike normal microflora, probiotic strains incorporate into general metabolism by mediating a spectrum of functions, e.g. maintaining colonisation resistance, nutrient metabolism, supplying the host with vital metabolites, regulation of local and adaptive immune responses, enhancing the intestinal barrier. Probiotics are applied in various diseases associated with general imbalances of the organism. Modern probiotic preparations are characterised by acid- and antibiotic-resistivity and safety, thus being suitable for treating gut microbiome-associated disorders in various age groups.Conclusion. Probiotic strains, as well as medications designed on their basis, are widely applied and show good promise. Further research into their properties will advance the prospects of probiotic treatment.

Nowadays there is a steady tendency to increase the number of patients with gallstone disease and metabolic syndrome. Increasingly, gallstone disease is called a non-canonical cluster of metabolic syndrome, because the main components of metabolic syndrome are also modifiable risk factors for gallstone disease. This article discusses the pathogenetic parallels in the development of gallstone disease and metabolic syndrome - insulin resistance and hormones of adipose tissue, lipid metabolism disorders, immune factors and the cytokine system. There are described possible effects of cholecystectomy on metabolism in patients with metabolic syndrome.
