Venous thromboembolism in patients with autoimmune disorders a small Hospital

Background: Patients with Autoimmune Disorders (AD) are at increased risk for venous thromboembolism (VTE). The natural history of VTE in these patients has been consistently evaluated by RIETE investigators this year. Methods: We used a newly created database in Reina Sofia's Hospital to compare the rates of VTE recurrences, major bleeding and death during the course of anticoagulation according to the presence or absence of autoimmune disorders. Results: No significant differences were detected in the baseline characteristics of patients except for the presence of idiopathic VTE and antiphospholipid antibodies. Patients with AD presented higher rates of recurrence while being under anticoagulant treatment and similar rates of bleeding and mortality. Conclusions: In a more local and homogeneous starting scenario than what was observed in the RIETE, patients with AD have a greater tendency to recur while being on anticoagulant treatment than patients without this condition.
