title: Morbidity of cytomegalovirus infection in recipients of heart or heart-lung transplants who received cyclosporine.
abstract: Forty-four heart and five heart-lung transplant recipients with cytomegalovirus (CMV) infection were investigated for risk factors associated with symptomatic CMV infection (17 patients) and CMV pneumonia (eight patients). Symptomatic infection was associated with primary rather than reactivated infection (P less than .005), younger age (P less than .005), heart-lung transplantation (P less than .001), and significant rises in titer of antibody to the early antigen of Epstein-Barr virus (P less than .001). Among recipients of heart transplants, patients with cardiomyopathy more often had symptomatic disease due to CMV (P less than .05). CMV pneumonia was associated with heart-lung transplantation and, in patients with primary CMV infection, earlier positive cultures for CMV after transplantation (P less than .02). CMV viremia was found in all patients with symptomatic infection, including the eight patients with CMV pneumonia, and the frequency of positive buffy coat cultures for CMV was significantly higher in patients with symptoms than in patients without symptoms (P less than .001). Neither symptomatic CMV infection nor CMV pneumonia was significantly associated with the use of antithymocyte globulin, restricted to therapy for rejection, and the use of high doses of acyclovir in 11 patients had no demonstrable impact on CMV culture positivity.
