Insights
Lamivudine treatment for children with chronic hepatitis B infection showed a higher virologic response rate compared to placebo over 52 weeks. This antiviral therapy was well-tolerated and effective in pediatric patients.
Area of Science:
- Pediatric Hepatology
- Viral Hepatitis Treatment
- Antiviral Therapies
Background:
- Chronic hepatitis B virus (HBV) infection affects children globally.
- Lamivudine is an established treatment for adult chronic hepatitis B.
- Pediatric efficacy and safety data for lamivudine were previously limited.
Purpose of the Study:
- To evaluate the efficacy and tolerability of lamivudine in children with chronic HBV infection.
- To determine the virologic response rate at 52 weeks of lamivudine treatment in pediatric patients.
- To assess secondary endpoints including seroconversion and liver enzyme normalization.
Main Methods:
- A randomized, double-blind, placebo-controlled trial was conducted.
- Children with chronic hepatitis B were randomized to receive lamivudine or placebo for 52 weeks.
- Virologic response was defined as the absence of hepatitis B e antigen and HBV DNA at week 52.
Main Results:
- A total of 191 children received lamivudine and 97 received placebo.
- Virologic response was significantly higher in the lamivudine group (23%) compared to placebo (13%) (P=0.04).
- Lamivudine was well-tolerated and improved seroconversion rates, normalized ALT levels, and suppressed HBV DNA.
Conclusions:
- Fifty-two weeks of lamivudine treatment significantly improved virologic response in children with chronic hepatitis B.
- Lamivudine represents a safe and effective therapeutic option for pediatric chronic hepatitis B.
- This study supports the use of lamivudine in managing chronic HBV infection in pediatric populations.
Background:
Lamivudine therapy is effective for chronic hepatitis B infection in adults. We evaluated the efficacy and tolerability of lamivudine as a treatment for chronic infection with hepatitis B virus (HBV) in children.
Methods:
Children with chronic hepatitis B were randomly assigned in a 2:1 ratio to receive either oral lamivudine (3 mg per kilogram of body weight; maximum, 100 mg) or placebo once daily for 52 weeks. The primary end point was virologic response (defined by the absence of serum hepatitis B e antigen and serum HBV DNA) at week 52 of treatment.
Results:
Of the 403 children screened, 191 were randomly assigned to receive lamivudine and 97 to receive placebo. The rate of virologic response at week 52 was higher among children who received lamivudine than among those who received placebo (23 percent vs. 13 percent, P=0.04). Lamivudine therapy was well tolerated and was also associated with higher rates of seroconversion from hepatitis B e antigen to hepatitis B e antibody, normalization of alanine aminotransferase levels, and suppression of HBV DNA.
Conclusions:
In children with chronic hepatitis B, 52 weeks of treatment with lamivudine was associated with a significantly higher rate of virologic response than was placebo.
