Acute cytomegalovirus infection and venous thrombosis: role of antiphospholipid antibodies.
Cytomegalovirus (CMV)-induced thrombosis has been reported in immunocompromised patients, such as transplant recipients and patients with AIDS. Recent cases also describe thrombotic phenomena in immunocompetent patients with CMV infection. Various mechanisms may explain the role of CMV in thrombosis: this virus can damage endothelial cells, activate coagulation factors, and induce production of antiphospholipid (aPL) antibodies. We present a case report of a previously healthy white woman with a pulmonary embolism associated with CMV infection and the presence of aPL antibodies, and we discuss the role of the aPL antibodies associated with CMV infection in the pathogenesis of thrombosis.
