Hemolytic anemia with positive direct antiglobulin test secondary to spontaneous cytomegalovirus infection in healthy adults.

Hemolytic anemia with positive direct antiglobulin test in association with spontaneous cytomegalovirus (CMV) infection is a very rare event in healthy adults. We report here 2 patients who have recently suffered from this complication and review similar cases previously reported in the literature. Because CMV serology is not routinely obtained as a part of hemolysis work-up, the true incidence of this complication may be underestimated. We believe that CMV infection should be considered in the differential diagnosis of hemolytic anemia in adults.
