An increased incidence of venous thromboembolism (VIE) is observed in human immunodeficiency virus (HIV)-infected patients. Only a limited number of studies described the effect of combined antiretroviral therapy (cART) on coagulation markers. In a prospective cohort study in cART-naive South African HIV-infected individuals the effect of initiating cART on markers of endothelial cell activation, coagulation and natural anticoagulation was studied. These markers were compared to the reference ranges for an HIV-uninfected control population recruited from hospital staff. A venous ultrasound of both legs was performed to detect asymptomatic deep venous thrombosis (DVT). A total number of 123 HIV-infected participants were included. The patients were predominantly black and severely immuno-compromised. The CD4 cell count increased and the HIV viral load decreased significantly after the initiation of cART (p
