The review presents an analysis of studies on the role of the intestinal microbiota and microbiome in lipid metabolism and the development of dyslipidemia, atherosclerosis and cardiovascular diseases. The role of the intestine as a metabolic organ with a multifactorial strain evolution, involved in lipid metabolism, cholesterol homeostasis and enterohepatic circulation is shown. The influence of microbial imbalance on the development of dyslipidemia and atherosclerosis is considered. Special attention is paid to preventive therapy with hypolipidemic probiotics. It is shown that the use of probiotics with hypolipidemic properties and consisting of a mixture of such strains asLactobacillus plantarumCECT7527, CET7528 and CECT7529, mixtures ofLactobacillus acidophilusLa-5,Bifidobacterium lactisBB-12,Bifidobacterium animalis lactisBB-12 contribute to reducing the level of LDL-C, CCS, TG, are safe and well tolerated, can be used as an adjuvant non-drug therapy in combination with hypolipidemic drugs for dyslipidemia, multifocal atherosclerosis.

Background. The novel coronavirus infection COVID-19 can be manifested by damage to the organs of the gastrointestinal tract (GIT). Damage to the gastrointestinal tract by the SARS-CoV-2 virus leads to a violation of the microbial-tissue complex of the mucous membrane of the digestive tract. A common gastroenterological manifestation of COVID-19 is diarrhea. Aim. Study of the clinical features of gastroenterological disorders and the possibility of optimizing the treatment of diarrheal syndrome in patients with COVID-19 with a mild form of viral infection. Materials and methods. The observation group consisted of 230 patients with mild COVID-19: K-group (n=115) with respiratory symptoms, I group (n=115) with gastrointestinal manifestations in combination and without signs of respiratory damage. In order to compare the effectiveness of treatment of diarrheal syndrome, patients of group I are randomized into 2 subgroups: Ia (n=58) prebiotic treatment (Zacofalk) and Ib (n=57) enterosorbents. Results. The development of gastrointestinal symptoms with SARS-CoV-2 infection is significantly more often noted in comorbid patients (67%). Gastrointestinal symptoms were dominated by diarrhea (93.9%) and flatulence (76.5%), in 1/3 of patients they were the first manifestos of infection. It was established that in 98.4% of patients of group I (against 42.6% of the K-group) signs of infectious intoxication were detected. In patients with gastrointestinal lesions, an elongation of the febrile period by 91.5 days was noted, a later (6 days) verification of the viral etiology of the disease. It was found that in patients of group I, the regression of clinical symptoms, the duration of viral disease, the dynamics of antibody formation, the prognosis for the development of IBS-like disorders in the post-infectious period depended on the treatment. In patients taking (Zacofalk), these indicators were significantly better. Conclusion. In mild cases, to reduce the severity of viral intestinal damage, for effective relief of intestinal symptoms, to reduce the risk of IBS-like symptoms, it is advisable to prescribe (Zacofalk) in an initial dose of 3 tablets per day.

Atrial fibrillation (AF) is a complex pathology that requires an integrated approach in both diagnosis and treatment, including optimal prevention of thrombosis, control of clinical symptoms, and identification and treatment of cardiovascular risk factors and comorbidities. The article analyzes some of the new positions of the recommendations of the European Society of Cardiology on atrial fibrillation, presented in 2020. Effective diagnostic and therapeutic approaches are discussed in the management of patients with AF in conditions of multimorbidity. The basic principles of the CC to ABC concept, introduced with the aim of improving a structured approach to the treatment of patients with AF, and the 4S-AF regimen necessary for decision on the use of oral anticoagulants, choosing a method of control of the rhythm and / or its frequency, choosing between ablation, cardioversion and antiarrhythmic drugs, as well as to determine the mode of treatment of major cardiovascular diseases. To improve the prognosis and achieve the best results in these patients, the most important is to reduce the risk of stroke, control cardiovascular risks and comorbidities, and ensure high adherence to the therapy within the framework of the concept of comprehensive patient protection. Rivaroxaban is considered by the authors of the article as one of the drugs that provides comprehensive anticoagulant protection of patients with AF. The efficacy profile of rivaroxaban in the prevention of acute cerebrovascular accident and high safety rates were confirmed in a population of multimorbid AF patients of different ages and the highest risk of stroke and / or bleeding.
