Insights
Natural interferon-alpha treatment effectively cleared hepatitis C virus (HCV) in 47% of Japanese children. This safe therapy showed promising long-term efficacy, especially for genotype 2a patients with low viral loads.
Area of Science:
- Hepatology
- Virology
- Pediatric Gastroenterology
Background:
- Investigated natural interferon (IFN)-alpha treatment efficacy in Japanese children with chronic hepatitis C.
- Study included 34 pediatric patients diagnosed with chronic hepatitis C.
Purpose of the Study:
- To evaluate the safety and effectiveness of natural IFN-alpha in treating chronic hepatitis C in children.
- To identify predictors of long-term treatment response.
Main Methods:
- Administered 6 months of natural IFN-alpha therapy to 34 children.
- Monitored serum hepatitis C virus (HCV) RNA titers and liver histology before, during, and after treatment.
- Followed patients for at least 12 months post-treatment.
Main Results:
- 47% of patients achieved normal alanine aminotransferase and undetectable HCV RNA 6 months after treatment cessation.
- Complete response observed in 80% of genotype 2a patients.
- Low initial HCV RNA (<102 copies/mL) after 1 month predicted complete response; histological improvement noted in most patients.
- Treatment was safe, with only mild, influenza-like symptoms reported.
Conclusions:
- Natural IFN-alpha is a safe and effective treatment for chronic hepatitis C in children.
- Early viral load reduction (<102 copies/mL after 1 month) and genotype 2a are positive predictors for sustained virologic response.
Background:
We investigated the efficacy of natural interferon (IFN)-alpha treatment in 34 Japanese children with chronic hepatitis C.
Methods:
Thirty-four children completed 6 months of therapy with natural IFN-alpha and were followed for 12 months or longer. We examined the serum hepatitis C virus (HCV) RNA titer and liver histology before, during, and after IFN treatment.
Results:
At 6 months after the cessation of IFN-alpha treatment, 16 patients (47%) had normal serum alanine aminotransferase concentration and no detectable serum HCV RNA. There were no major side-effects, excluding some influenza-like symptoms during the IFN-alpha treatment. Most genotype 2a patients had a complete response (80%). Moreover, patients who had a low HCV RNA titer (<102 copies/mL) after 1 month of IFN-alpha treatment became complete responders at 6 months after the cessation of treatment. Histological improvement was observed in almost all patients after IFN-alpha treatment.
Conclusion:
Interferon-alpha treatment is safe and effective for children with chronic hepatitis C and has no serious side-effects. A HCV RNA concentration of <102 copies/mL after 1 month of IFN-alpha treatment and genotype 2a may be useful predictors of long-term IFN efficacy.
