Antiphospholipid antibody syndrome manifesting as a deep venous thrombosis and pulmonary embolism in a patient with HIV.

Although antiphospholipid antibodies are commonly detected in patients with HIV disease, the clinical manifestations of antiphospholipid syndrome are uncommon. The authors describe a woman with HIV and elevated antiphospholipid antibody levels who presented with deep venous thrombosis and pulmonary embolism. This case contradicts the general belief that these antibodies are not clinically significant in patients with HIV.
