Purpose. The characteristics, etiology, natural history, and direct and indirect effects of CMV disease in solid organ transplant recipients are described. Summary. CMV is a common herpesvirus that may be present in the donor or recipient of a solid organ transplant. Even though it is rarely pathogenic in healthy patients,. transplant recipients are at risk for CMV viremia and symptomatic disease due to their immune-suppressed status. In addition to symptoms directly attributed to active disease, CMV can have a variety of indirect effects. Indirect effects may include additional infectious complications, posttransplant lymphoproliferative disease, allograft rejection, allograft loss, or death, The three most prevalent risk factors for CMV infection are CMV seronegativity in a recipient of an organ from a CMV-seropositive donor, the type of organ transplanted, and the degree of immune suppression. CMV prophylaxis is effective at preventing disease, but may result in a delayed onset where CMV disease occurs once the prophylaxis is stopped. Conclusion. Knowledge of risk factors for CMV infection and disease, the natural history in transplant recipients, and its direct and indirect effects will help clinicians make appropriate decisions regarding the use of preventive strategies.
