Abstract

Background: Thrombosis is a rare complication of cytomegalovirus (CMV) infection in immunocompetent patients. The clinical circumstances of this complication have never been studied, to the best of our knowledge. Aim: We reviewed all reports on CMV-associated thrombosis in immunocompetent adults found in the literature, in search for thrombosis risk factors other than CMV. Methods: Our search yielded 32 case reports and case series on CMV-associated thrombosis in immunocompetent adults. Reports on immunocompromised patients, infants and elderly patients were excluded. All reports were reviewed for other, acquired as well as inherited, predispositions for thrombosis. Results: Reports on 39 immunocompetent adults were reviewed, mean age for which was 34.9 ± 10.8 years. Overall, 14 (35.9%) patients had one or more acquired predispositions for thrombosis; 16 (45.7%) of the 35 patients that were investigated for inherited thrombophilias had one or more inherited predispositions for thrombosis. Only 12 (34.3%) patients were found to have no acquired or inherited predispositions for thrombosis other than CMV. The most common (n = 13; 33.3%) acquired predisposition for thrombosis was daily use of oral contraceptives. The most common (n = 6; 17.1%) inherited predisposition for thrombosis was factor V Leiden mutation. Conclusions: Most immunocompetent adults with CMV-associated thrombosis have other acquired or inherited predispositions for thrombosis. Hence, addressing these predispositions in patients with CMV-associated thrombosis may be of great clinical importance.
