Risk factors for venous thromboembolism in adults with hemoglobin SC or Sβ(+) thalassemia genotypes.

Introduction: Venous thromboembolism (VTE) is common in sickle cell disease (SCD); however, the risk factors associated with VTE in patients with sickle variant syndromes are not known. The primary aim of this study was to determine hematologic and clinical risk factors for VTE in adults with hemoglobin SC or Sβ(+) thalassemia genotypes.

Materials And Methods: We conducted a retrospective cross-sectional analysis of patients with hemoglobin SC and Sβ(+) thalassemia genotypes followed at the Sickle Cell Center for Adults from 2008 to 2012.
