title: Ganciclovir prophylaxis for cytomegalovirus infection in pediatric allogeneic bone marrow transplant recipients.
abstract: Twenty-nine pediatric allogeneic bone marrow transplant (BMT) recipients, ages 2-17 years, were followed prospectively for cytomegalovirus (CMV) infection. Patients at risk received ganciclovir (GCV) prophylactically at a dose of 5 mg/kg/day i.v., 3 to 5 days per week, until day 100. Surveillance blood and urines were obtained weekly. Twelve patients developed DMV infection: one patient died with CMV interstitial pneumonitis on day 19 post-transplant prior to initiating GCV prophylaxis; 10 patients developed CMV viremia (n = 9) or viruria (n = 1) between day 30 and day 95 (median day 50) while receiving GCV prophylaxis; and one patient developed asymptomatic CMV viruria on day 130, 1 month after completing GCV prophylaxis. Patients with breakthrough infections on prophylaxis were treated with intensified GCV and i.v. immunoglobulin. No patient developed visceral involvement, although five patients had recurrent viremia. Six of the seven long-term survivors continued to excrete CMV in the urine intermittently for 6 to 28 months post-transplant. GCV was well tolerated with transient, mild neutropenia in five patients and thrombocytopenia in four patients. No extramedullary toxicity was encountered. GCV prophylaxis at a dose of 15-25 mg/kg/week is not adequate to prevent CMV reactivation in children receiving marrow transplants from unrelated donors and/or T cell-depleted grafts.
