title: [Herpes encephalitis in newborn infants. Retrospective study of 12 cases].
abstract: BACKGROUND
  Herpes simplex virus (HSV) may cause severe disease in neonates with high mortality and devastating sequelae. Adenine arabinoside (ara-A) and acyclovir can be effective in treating the neonatal disseminated disease, but optimal doses of the drugs are still debated.
  
  
  METHODS
  The files of 12 neonates treated for HSV infection between May 1983 and April 1989 in 9 departments of pediatrics were studied. The following data were analysed: age at initial signs, clinical manifestations, CSF abnormalities, viral and immunological studies, imaging techniques used to detect brain damage, doses and duration of treatment.
  
  
  RESULTS
  The mean age at the first infectious signs was 12.3 +/- 9.3 days and neurological manifestations were first seen at 18.3 +/- 7.7 days. Acyclovir was given intravenously for 2 to 4 weeks at doses of 30 mg/kg/24 hr (5 patients) or 60 mg/kg/24 hr (7 patients) at an average of 7.7 days after the first clinical manifestations. The initial dose of 30 mg/kg/24 hr was increased to 50 or 60 mg/kg/24 hr in 3 patients. Five patients died during treatment, and 5 had severe sequelae; follow-up for the 2 remaining patients was not possible. There was no correlation between prognosis and the dose of acyclovir, which was well tolerated in all patients.
  
  
  CONCLUSIONS
  The best results are obtained when treatment is started early. This retrospective study failed to show any dose-dependent difference in the efficacy of acyclovir. A prospective study with different doses would be useful.
