title: Failure of ganciclovir prophylaxis to completely eradicate CMV disease in renal transplant recipients treated with intense anti-rejection immunotherapy.
abstract: Ganciclovir prophylactic regimens have been shown to be effective in renal transplant recipients at risk for primary (donor seropositive/recipient seronegative) and secondary (recipient seropositive) cytomegalovirus (CMV) disease. However, in addition to serologic factors, the type and intensity of the administered immunosuppression is a strong risk factor for CMV disease. Since January 1995, we have utilized a potent immunosuppressive protocol selectively in recipients at high risk for immunologic graft loss, defined as retransplant recipients, recipients with delayed graft function, non-Caucasian recipients, and recipients suffering from acute rejection. Between January 1995 and December 1996, 110 consecutive renal transplants were performed in recipients who were either CMV seropositive or received an allograft from a CMV-seropositive donor. All recipients received ganciclovir prophylactic therapy for 3 months post-transplant. Group I (N = 43) consisted of recipients at high-immunologic risk for graft loss as defined above. These recipients were treated with an intense anti-rejection immunotherapeutic regimen consisting of Cellcept, Neoral, and prednisone, with the frequent addition of antilymphocyte antibody therapies and intravenous methylprednisolone. The remaining 67 recipients (group II) were treated with a less intense immunotherapeutic regimen consisting of azathioprine, Neoral, and prednisone. The incidence and severity of CMV disease and the patient and allograft survival were compared. The incidence of CMV syndrome was greater in group I (28%) compared with group II (7%), and was statistically significant (p < 0.05). The 1-yr patient and graft survival were similar, 95 and 91%, respectively, for group I compared with 97 and 97%, respectively, for group II. These data suggest that 3 months of ganciclovir prophylactic therapy is significantly less effective for the prevention of CMV disease in renal transplant recipients at high risk for acute rejection treated with an intense immunotherapeutic regimen. These data suggest that more effective prevention of CMV disease in these high-risk recipients will require the addition of other anti-viral agents, such as immunoglobulin preparation to the prophylactic regimen.
