title: Varicella in pediatric liver transplant patients: a retrospective analysis of treatment and outcome.
abstract: BACKGROUND
  Varicella is a common childhood disease that can cause morbidity and mortality among immunosuppressed patients. There have been few previous studies monitoring the course of pediatric liver transplant patients with acute varicella. The aim of this study was to evaluate the treatment, outcomes, and complications of pediatric liver transplant patients admitted with acute varicella infection.
  
  
  METHODS
  A retrospective chart review was carried out based on discharge diagnoses of orthotopic liver transplant and varicella among pediatric patients (age range, birth-18 years) admitted to the UCLA Medical Center between 1985 and 2001.
  
  
  RESULTS
  Five hundred fifty-six pediatric patients received liver transplantations between 1985 and 2001. Twenty-two of these patients were admitted to the UCLA Medical Center with varicella (11 females, 11 males). No patients were treated on an outpatient basis. Mean age of the patients was 6 years (range, 1-16 years). None of these patients received the varicella vaccine before hospitalization. On admission, 5 of 22 patients (23%) had received varicella zoster immunoglobulin within 96 hours of exposure. The mean length of hospitalization was 6 days (range, 2-11 days). All immunosuppression dosages were reduced during the admissions. None of the patients had been treated with high-dose corticosteroids for acute rejection before the onset of the varicella infection. Patients were treated until defervescence with intravenous acyclovir and until their varicella lesions crusted. Patients were discharged with oral acyclovir to complete a 10-day course (including the intravenous treatment). No patients had complications from the varicella infection. A complication of an elevated serum creatinine for one patient was noted with the intravenous acyclovir treatment. This patient had associated headache and nausea that resolved when the creatinine level returned to normal.
  
  
  CONCLUSIONS
  There were no complications or dissemination of varicella infection among our pediatric liver transplant patients. Further prospective randomized trials are required to evaluate the management of pediatric liver transplant patients infected with varicella.
