Treatment of children with HBeAg-positive chronic hepatitis B: a systematic review and meta-analysis.

BACKGROUND

Effective management of children with chronic hepatitis B is still an unresolved issue.

AIM

To assess the outcome of different therapeutic regimens among children with HBeAg-positive chronic hepatitis B.

METHODS

Electronic database searches identified clinical trials that completed specific periods of treatment and follow-up. Sustained response rates were defined by the loss of HBV DNA and HBeAg, and by the normalization of liver enzymes. The loss of HBsAg and seroconversion to anti-HBs were also listed.

RESULTS

Our searches found 20 eligible articles (1112 enrolled patients, 2-18 years old). Interferon-alpha therapy showed significantly higher sustained response rate and loss of HBsAg than no therapy (Odd's ratio 3.0, 95% confidence interval 1.6-5.4; and 2.3, 1.1-11.3, respectively). The sustained response rate was not significantly different between interferon and interferon plus lamivudine, or plus prednisone, or plus hepatitis B vaccine; this rate was significantly higher for interferon compared with combined interferon plus levamisole or vitamin E.

CONCLUSION

Interferon-alpha is still the most effective treatment option for children with HBeAg-positive chronic hepatitis B. Randomized trials are warranted for further comparing interferon to newer antiviral agents in terms of efficacy, safety, emergence of mutant variants, and cost/benefit ratio.
