Comparison of Intravenous Ganciclovir Followed by Oral Acyclovir with Intravenous Ganciclovir Alone for Prevention of Cytomegalovirus and Epstein‐Barr Virus Disease After Liver Transplantation in Children

A randomized trial was performed to compare the sequential use of 2 weeks of intravenous ganciclovir (10 mg/kg.d) followed by 50 weeks of high-dose oral acyclovir (800 mg/m2 four times daily) with 2 weeks of intravenous ganciclovir alone as prophylaxis for cytomegalovirus (CMV) and Epstein-Barr virus (EBV) disease after pediatric liver transplantation. CMV disease was diagnosed for seven of 24 patients treated with ganciclovir followed by high-dose oral acyclovir compared with two of 24 children treated with ganciclovir alone (P = .048). Similarly, the rate of CMV disease among high-risk patients (CMV-positive donor/CMV-negative recipient) treated with the combination regimen was higher than that among high-risk patients treated with ganciclovir alone (four 57% of seven vs. zero of five, respectively; vs P < .05). The rate of EBV disease among patients treated with the combination regimen (eight 33% of 24) was similar to that among patients treated with ganciclovir alone (five 21% of 24; P = not significant). We conclude that sequential prophylaxis with 2 weeks of intravenous ganciclovir followed by 50 weeks of high-dose oral acyclovir did not decrease the frequency of CMV or EBV disease after pediatric liver transplantation when compared with 2 weeks of intravenous ganciclovir alone.
