Long-term prognosis of renal transplantation after preemptive treatment of cytomegalovirus infection

A role for cytomegalovirus (CMV) infection in the etiologies of acute and chronic rejection in renal allograft recipients has been suggested. We previously reported that preemptive treatment of CMV infection with ganciclovir in kidney transplant patients was safe and effective. We nom present a retrospective analysis of 169 consecutive renal transplant patients, of whom 87 (51.5%) received preemptive treatment with ganciclovir (CMV(+) group). No patient died of CMV infection. Actuarial graft and patient survival rates were not different between the CMV(+) and the CMV(-) groups (graft survival: 68% and 69%; patient survival: 89% and 88%, respectively). At the end of the study, the mean plasma creatinine levels were not statistically different between the two groups (185+/-13 and 166+/-12 mu mol/L for the CMV(+) group and the CMV(-) group, respectively). These results suggest that preemptive treatment of CMV infection with ganciclovir may prevent the CMV-induced renal injury and graft loss.
