BACKGROUND: We compared the efficacy and safety of 2 different treatments of CMV infection, including asymptomatic CMV replication and CMV disease.

MATERIAL AND METHODS: 852 renal transplantation recipients, including asymptomatic CMV replication and CMV disease, received antiviral therapies of intravenous acyclovir or comprehensive anti-infection solution, mainly with intravenous ganciclovir. Effect, time, acute allograft rejection, and safety were analyzed during the antiviral therapy

RESULTS: The total effective rates were higher with ganciclovir in both asymptomatic CMV replication (98.96% vs. 84.90%) and CMV disease (96.29% vs. 50.36%). Ganciclovir significantly shortened antiviral therapy duration in both asymptomatic CMV replication (15.0±2.3 days vs. 16.0±3.4 days) and CMV disease (19.7±3.1 days vs. 21.5±4.0 days). The acute allograft rejection incidences were significantly lower with ganciclovir in both asymptomatic CMV replication (8% vs. 14%) and CMV disease (11% vs. 22%). CMV-IEA was detected in renal grafts of patients with acute rejection. There was more CMV-associated acute rejection using acyclovir than using ganciclovir. Except for the higher incidence of anemia leucopenia and anemia with ganciclovir, the safety profiles of both drugs were similar.

CONCLUSIONS: Comprehensive anti-infection solution, mainly with intravenous ganciclovir, can effectively treat CMV infection, shorten duration of therapy, and decrease acute rejection. The few adverse effects had negligible effects on use of ganciclovir.
