Venous thromboembolism (VTE) is a preventable cause of morbidity and mortality in acutely ill patients hospitalized in medical departments. Thromboprophylaxis with anticoagulants was shown to be safe and effective in medical patients with high risk to develop VTE. Despite guidelines recommendations, the rate of thromboprophylaxis in those patients is low. The objective of the study was to evaluate the rate of VTE risk assessment in routine medical department practice, the rate of eligible patients for thromboprophylaxis, the rate of patients who received thromboprophylaxis, and their outcome. Medical records of consecutive patients (3000 at 2013, 1000 at 2018) hospitalized in medical department were reviewed, retrospectively, for demographic, clinical characteristics, thromboprophylaxis treatment with enoxaparin and outcome (up to 90 days following discharge). Padua score was used for VTE risk assessment. VTE diagnosis was based on clinical suspicion. The mean patient's age (52.6% females) was 67.95 ± 21.56 years. 21% were eligible for thromboprophylaxis. Routine VTE risk assessment rate increased significantly following its incorporation into quality parameters, but the rate of treated patients was low (22% at 2013; 46% at 2018). The patients who received thromophylaxis were sicker compared to eligible patients without thromboprophylaxis. The rate of symptomatic VTE was low (0.24%; 0.12% and 0.55% for low and high VTE risk, respectively). Thromboprophylaxis did not have significant effect on the low number of VTE events. No major bleeding was observed. Major efforts are still needed to increase the rate of thromboprophylaxis in all eligible medical patients according to the guidelines recommendations.
Rationale:The integrase inhibitor dolutegravir is now recommended as first-line treatment for HIV. A single case of myocarditis after treatment with dolutegravir was reported in the FLAMINGO trial. We present here 2 cases of severe myocarditis that occurred shortly after the initiation of dolutegravir treatment.Patients concerns:The first case is a 45-year-old female who developed severe congestive heart failure and died, weeks after the initiation of dolutegravir treatment (for simplification of her antiretroviral regimen). The second case was a 51-year-old male who presented with effort dyspnea 3 weeks after the initiation of dolutegravir treatment and was later diagnosed as severe congestive heart failure. The treatment was changed and the patient survived, but he still suffers from severe heart failure with functional impairment.Diagnosis and Outcome:Patient 1 died, patient 2 suffers from severe heart failure.Lessons:We discuss here the possible relationship between the initiation of dolutegravir treatment and the development of lymphocytic myocarditis in our patients, and we suggest a possible mechanism.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
