PROTOCOL OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients are stratified according to disease (CNS disease with or without cutaneous involvement vs disseminated disease with CNS involvement).
All patients receive acyclovir IV every 8 hours on days 1-21. On day 19, patients undergo a lumbar puncture and must have a negative CSF PCR to be randomized. If patients have a positive CSF PCR on day 19, they continue to receive acyclovir IV every 8 hours. Treatment continues every 7 days with a repeat CSF PCR on the fifth day until a negative CSF PCR result is achieved. Patients are then randomized to one of two treatment arms.
Arm I: Patients receive oral acyclovir three times a day for 6 months. Arm II: Patients receive placebo. In case of cutaneous recurrence during the first 12 months of the study, patients receive open label oral acyclovir (if CSF PCR is negative) or acyclovir IV (if CSF PCR is positive) for 5 days. Patients may or may not continue on study drug following this treatment.
Patients are followed at 6, 12, 24, 36, 48, and 60 months of age.
