title: Does interferon and ribavirin combination therapy increase the rate of treatment response in children with hepatitis C?
abstract: BACKGROUND
  Interferon-alpha was the first accepted treatment of chronic hepatitis C. In recent years, adding ribavirin has produced better response rates in adult patients than monotherapy with interferon-alpha. Whether adding ribavirin also improves treatment results in pediatric patients remains unclear.
  
  
  METHODS
  Twelve patients were given 3 million U/m 2 subcutaneous interferon-alpha three times weekly and 15 mg/kg oral ribavirin daily, and 10 patients were given only 3 million U/m 2 subcutaneous interferon-alpha three times weekly for a total of 12 months.
  
  
  RESULTS
  The dropout rate was 22.8% (25% for patients receiving combination treatment versus 20% for those receiving monotherapy). At the end of treatment, viral clearance was achieved in 50% of the patients who received combination treatment versus 30% of those who received monotherapy. After 12 months of posttreatment follow-up, sustained response rates were 30% and 41.7%, respectively. Of those who responded to treatment, 66.7% had received ribavirin whereas 37.5% of nonresponders had received ribavirin therapy.
  
  
  CONCLUSIONS
  Adding ribavirin to interferon treatment improved end-of-treatment response rates in children with chronic hepatitis C. Tolerance of treatment was similar to tolerance of monotherapy. However, studies of greater numbers of pediatric patients with longer follow-up periods are necessary to determine prolonged sustained response.
