Efficacy and safety in chronic hepatitis B adolescent patients with lamivudine therapy / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analysis the efficacy and safety of lamivudine (made in China) therapy for 52 weeks in adolescent patients with chronic hepatitis B (CHB).</p><p><b>METHODS</b>One hundred and five teenage CHB patients were treated with lamivudine 100 mg once daily for 52 weeks. Patients with elevated ALT at baseline were in group 1 and those with normal ALT were in group 2. The changes of HBV DNA, HBV seromarkers and ALT at the end of 12, 24 and 52 weeks after lamivudine therapy were compared with those at baseline. Adverse events were recorded and evaluated.</p><p><b>RESULTS</b>At the end of 52 weeks of lamivudine therapy, HBV DNA-ve, HBeAg loss and anti-HBe seroconversion were observed in 92.0%, 24.4% and 22.0% in group 1 patients and 76.1%, 14.2% and 14.2% in group 2 patients respectively. No significant differences were found between two groups. At 12, 24 and 52 weeks, normalization rates of ALT were 59.0%, 66.7% and 76.0%, normal ALT with undetectable HBV DNA were 44.9%, 64.1% and 70.7% at the same time. During 52 weeks lamivudine treatment 26 mild adverse events were observed in 18 patients.</p><p><b>CONCLUSION</b>Lamivudine can inhibit HBV replication rapidly and normalize ALT in majority adolescent CHB patients. HBeAg loss or seroconversion of anti-HBe was observed in some of these patients. All patients in this study were safety and well tolerated.</p>
