THE STATE OF THE HEMOSTASIS SYSTEM AND PREVENTION OF THROMBOEMBOLIC COMPLICATIONS IN PATIENTS WITH ULCERATIVE COLITIS WHO SUFFERED SARS-COV-2 INFECTION DURING THE 2020-2021 PANDEMIC
Relevance: Coronavirus infection MERS-CoV 2, according to current data, causes disorders in the hemostasis system and, thereby, negatively affects the course of a number of other diseases. In the pathogenesis of ulcerative colitis, disorders of hemostasis and local hemocirculation play an important role, which determines the relevance of their assessment after COVID-19 infection.
Objective: Comparative analysis of the effect of SARS-CoV-2 infection on the state of the hemostasis system and the risk of thromboembolic complications in ulcerative colitis.
Research materials and methods: The study design is a prospective single–center clinical trial. 92 patients with ulcerative colitis who were under outpatient and clinical supervision in the conditions of the Medical Center of the NAO MUS (Semey) in the period 2019-2022 were examined. Of these, 57 cases of laboratory and clinically confirmed SARS-CoV2 disease were identified among persons included in the clinical group during the 2020-2021 pandemic.
To study the hemostasis system, the determination of ADP-induced aggregation, fibrinogen content, APTT, RPDF, RFMC, antithrombin III activity, fibrinolysis time were used. Thromboelastography was performed. The frequency of thromboembolic complications was analyzed by the actuarial method.
Results of the study: In groups of patients with ulcerative colitis, there was an excess of the vascular-platelet link of the hemostasis system over the control group, as well as dependence on the presence of a history of SARS-CoV2. A significant excess of aggregation indicators and a decrease in disaggregation were determined in patients who underwent SARS–CoV2. According to the IAT level, it was 24.6% (p=0.025), CIAT – 31.1% (p=0.019), CA - 31.3% (p=0.021), Willebrand factor - 65.9% (p=0.007). The degree of decrease in IDT was 21.5% (p=0.034). The time of development of stable thrombosis during thromboelastography was significantly reduced in the subgroup of SARS-CoV2 (36.7%, p=0.018). In contrast to the comparison group, the trend in the frequency of thromboembolic complications in SARS-CoV-2 patients was aimed at increasing.
