Vitamin E treatment for children with chronic hepatitis B: a randomized placebo controlled trial

To evaluate the safety and efficacy of Vitamin E in children with chronic hepatitis B.

We randomly assigned patients with chronic hepatitis B, positive for hepatitis B e antigen (HBeAg), to receive either Vitamin E or placebo once daily for 6 mo in a 3:1 ratio and double-blind manner. The primary end point was HBeAg seroconversion, defined as the loss of HBeAg, undetectable levels of serum hepatitis B virus DNA, and the appearance of antibodies against HBeAg 12 mo after therapy.

At baseline visit, 49 patients had normal and 43 had increased serum aminotransferase levels. Twenty-nine patients did not respond to previous treatment with interferon-alpha or lamivudine. Seventy-six children completed the study; 16 were non-compliant (n = 7), lost to follow-up (n = 7), or started another antiviral treatment (n = 3). Intention-to-treat analysis showed HBeAg seroconversion in 16 children (23.2%) treated with Vitamin E and two (8.7%) in the placebo group (P = 0.13). Vitamin E was well tolerated.

There is only a tendency that Vitamin E may promote HBeAg seroconversion. Therefore larger studies are needed to clarify the role of antioxidants in the therapy of chronic hepatitis B.
