Abstract

Most of the effects and complications of cytomegalovirus (CMV) infection are still unknown, even though its tropism for the endothelium has been extensively investigated. In fact, CMV is suspected to be a cause of venous thrombo-embolism (VTE) since 1974, but there is still no consensus about the management of CMV-related thrombosis and how to prevent it. Cytomegalovirus-related thrombosis has been reported mostly in immunocompromised patients, rarely in immunocompetent individuals. In order to identify potential risk factors of CMV-related thrombosis, we performed a systematic review of the literature regarding immunocompetent patients with cytomegalovirus infection and thrombosis.We found 115 cases with a mean age of 37.36 years (SD ± 16.43 years). Almost half the female patients were assuming EP contraception at the time of the event, and almost half the patients were affected by a coagulation disorder. Interestingly, just two women and four men had no risk factor for thrombosis other than the CMVinfection at the time of the event. In conclusion, coagulation disorders and EP contraception have to be taken into a great deal of consideration in patients with CMV infection, since they could be important risk factors for VTE. Knowing the correlation with coagulation disorders, the use of anticoagulation drugs cannot be considered overtreatment. It was not feasible to determine the usefulness of an antiviral treatment. Further studies, even randomized ones, are required to determine the usefulness of antiviral drugs and the real prevalence of CMV-related VTE.
