Patients with normal alanine aminotransferase and negative hepatitis B virus DNA at the end of the treatment were responders and those with persistent response 16 weeks off treatment were considered having durable response.RESULTS: Three patients dropped out and 33 patients completed the study. Eight patients (24.2%) had normal alanine aminotransferase, 25 patients (75.8%) had increased alanine aminotransferase. Thirty patients (90.9%) were hepatitis B envelope antigen negative. Two patients (25%) with initial normal alanine aminotransferase and 7 patients (28%) with increased enzyme level, responded at end of treatment. One patient with positive hepatitis B envelope antigen responded to treatment. Only one patient relapsed during follow-up period off treatment.CONCLUSION: Lamivudine is associated with durable response in patients with hepatitis B virus and negative hepatitis B envelope antigen. Longer treatment for more than one year may be required to improve response rates.
