[Potential for infusion correction of COVID-19-associated endotheliopathy].

AIM: To evaluate the relationship between the systemic inflammatory response and the severity of COVID-19-associated endotheliopathy and the effect of succinate-containing crystalloid solution (sodium meglumine succinate) on it in patients with severe COVID-19. MATERIALS AND METHODS: Clinical and laboratory parameters of 53 intensive care unit's patients with COVID-19 complicated by community-acquired bilateral multisegmental pneumonia were analyzed. Intensive therapy complex of 27 patients (study group) included daily infusion of 1.5% solution of sodium meglumine succinate (Reamberin) in the daily dose of 10 ml/kg for at least 11 days (or during the whole stay in the unit). A similar volume of Ringer's solution was present in the control group of 26 patients. The levels of endotheliocytosis, homocysteine, and systemic inflammatory response were determined at all stages of the study. RESULTS: The evaluation of endotheliopathy degree in the meglumine succinate group showed a significant reduction of initially elevated levels of endotheliemia and homocysteinemia at all study stages. The pattern of changes in the study group was highly correlated (r=0.90-0.96) with the dynamics of systemic inflammatory response parameters-fibrinogenemia, C-reactive protein and interleukin-6 levels. As normalization of the immune imbalance, we regarded the termination of lymphopenia in the Reamberin group. CONCLUSION: Early inclusion of Reamberin infusion into intensive therapy of severe COVID-19, in comparison with Ringer's solution, leads to significant and stable correction of the severity of systemic inflammatory response, which in turn is naturally reflected in the severity of endothelial dysfunction, multiple organ failure, and also leads to a decrease in 28-day mortality.

[Pharmacotherapy of inflammatory bowel diseases: efficacy performance and safety management].

Treatment of inflammatory bowel diseases IBD (Crohns disease, ulcerative colitis) is aimed at achieving clinical, endoscopic and histological remission, minimizing surgical complications, and ensuring a normal quality of life. However, the use of medical treatment is potentially associated with various adverse events, among which infectious complications, malignant neoplasms, as well as myelotoxicity, hepatotoxicity, skin lesions and others. The risk of side effects depends on the type of drug therapy (5-aminosalicylates, thiopurines, biologicals, etc.), the duration of treatment, the presence of extra-intestinal manifestations, etc. The article provides an overview of data on both the effectiveness and frequency of various side effects of the main classes of drugs in IBD, presents methods of investigation which can predict the effectiveness and development of side effects, the implementation of which can be considered as a variant of personalized therapy in IBD.
