RESUMEN
BACKGROUND: Cytomegalovirus (CMV) is one of the serious viral infections after organ transplantation, especially in patients receiving anti-lymphocyte antibodies. Prevention of the infection using antiviral chemotherapy (ganciclovir) has gained interest in the transplant community due to the availability of quantitative methods for viral detection and monitoring. METHODS: Forty-six CMV seropositive kidney transplant recipients were assigned to receive induction immunosuppression with anti-thymocyte globulin (ATG, Fresenius). Prophylactic intravenous ganciclovir was administered for 2 weeks at a dose of 5 mg/kg/d (adjusted to kidney function) starting from the day of surgery. Patients were monitored regularly for CMV infection or disease over 1 year posttransplant. The time to CMV manifestation, the number of antigenemia assay-positive cells, the clinical severity of infection, the incidence of acute rejection, the graft function, and the duration of hospital stay were evaluated. This group was compared to a historical matched control cohort (n = 37) transplanted earlier who did not receive prophylactic ganciclovir. RESULT: The incidence of CMV disease was significantly less among the prophylaxis than the control group (6/46 patients [13%] vs 16/37 patients [43.2%], P = <.004). The time to develop CMV manifestations was much longer in the prophylaxis group than in the control group (median 92 vs 32 days, P
