Abstract
AIM: To evaluate the impact of combination therapy with Lamivudine and Adefovir for treatment of chronic hepatitis B in Lamivudine-resistant patients. METHODS: Among the 110 adult chronic hepatitis B Iranian patients whom were treated with Lamivudine, for 36 months, nineteen patients (17%) with no any biochemical and viral responses to Lamivudine alone, were selected and enrolled in the study. Due to resistancy, Adefovir was added to Lamivudine, and continued for 30 months. We measured HBV_DNA viral load and serum AST, ALT in 0, 12, 24, 30 and 0, 6, 12, 18, 24, 30 months, respectively. RESULTS: Between biochemical and viral characteristics, Repeated Measure analysis identified just biochemical markers— Aspartate Aminotransferase level (AST) (P = 0.002) and Alanine Aminotransferase level (ALT) (P = 0.007) —as predictors of response to treatment, while, viral marker—HBV DNA load—was not statistically significant (P = 0.128). CONCLUSIONS: Treatment for a long time, such as 21.5 ± 8.8 months, with Lami- vudine and Adefovir, can cause liver enzymes including AST and ALT, decreasing and being normal. But, this finding is not indicative, for HBV-DNA viral load.

Summary
Chronic hepatitis B is one of the main causes of liver damage such as liver cirrhosis and hepatocellular carcinoma [1]. These events can be prevented by appropriate therapy. The main problem with this drug is increasing resistancy more than 65% in five years treatment [2]. Another important issue, is lower potency of using antiviral drugs, separately, compared with administration together. In order to evaluate the efficacy of Lamivudine plus Adefovir therapy with regards to prevent long-term mentioned harms of disease, in patients with resistancy to Lamivudine alone, we performed this study
