Possibilities of Autologous Fecal Microbiota Transplantation in patients with obesity and diabetes mellitus

Obesity and type 2 diabetes mellitus (T2DM) are major problems for public health all over the world. According to retrospective research, the prevalence of obesity has doubled in more than 70 countries since 1980, as well as the prevalence of obesity complications (atherosclerotic cardiovascular diseases, nonalcoholic fatty liver disease and their complications. There are many drug therapies for T2DM, but it is difficult to achieve a stable, clinically relevant effect on a long-term basis. The fact that a patient has both conditions makes it difficult to optimize carbohydrate metabolism and to achieve normal body weight. Many antidiabetic drugs cause weight again, which, in turn, contributes to the growth of insulin resistance (IR) and requires further intensification of therapy.In the last few years, there is a growing evidence of the relationship between the gut microbiota (GM), obesity and T2DM. There has been a steady growth of interest in such medical technology as fecal microbiota transplantation (FMT) in the world. Since there is data on the association of the gut microbiota (GM) with the development of IR and T2DM, the possibility of FMT can potentially be one of the new methods of treatment. This review presents the current state of the problem and discusses the possibility of modifying GM as a therapeutic strategy in obesity and T2DM with an accent on autologous fecal microbiota transplantation.
