Prevalence of Nosocomial Venous Thromboembolic Complications in New Tuberculosis Patients and Relapses: Data from the Moscow City Registry (A Multicenter Study)

The objective: to evaluate VTEC in new tuberculosis patients and relapses, to determine main factors influencing its development (according to data of the patients admitted to Moscow tuberculosis hospitals)Subjects and Methods. Based on the data of epidemiological tuberculosis monitoring system of Moscow, treatment outcomes of 4609 tuberculosis patients admitted to tuberculosis hospitals from 2020 to 2022 were retrospectively analyzed. The incidence of VTEC was estimated.Results. Totally 214/4609 cases of VTEC were identified (4.6%; 95% CI 4.1-5.3%), among which the incidence of DVT made 3.5% (95% CI 3.0-4.1%), SVP 1.5% (95% CI 1.2-1.9%), and PATE 0.6% (95% CI 0.4-0.8%). The most significant risk factors of thrombotic complications in tuberculosis patients were identified, those factors included HIV infection (RR 3.8; 95% CI 2.7-4.5) and fibrous cavernous form of pulmonary tuberculosis (RR 9.1; 95% CI 4.7-17.6). The overall prevalence of VTEC in tuberculosis hospitals was 3 or more times higher than in general clinics (according to the published data).Conclusion. The data obtained indicate that patients hospitalized for pulmonary tuberculosis face a high risk of VTEC development that requires prediction and prevention.
