PROTOCOL OUTLINE:
This is a randomized, double blind, placebo controlled, multicenter study.
All patients undergo a lumbar puncture and then receive acyclovir IV every 8 hours on Days 1-14. On Day 12, patients may undergo a lumbar puncture (at discretion of investigator). Whole blood is obtained for herpes simplex virus PCR analysis. Upon completion of intravenous therapy, patients with a negative CSF PCR are randomized to one of two treatment arms.
Arm I: Patients receive oral acyclovir three times daily for 6 months.
Arm II: Patients receive placebo three times daily for 6 months.
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.
