RESUMO
OBJECTIVE: To evaluate the efficacy and safety of adefovir dipivoxil in treatment of decompensated liver cirrhosis patients with YMDD motif mutation during lamivudine therapy. METHODS: The disease relapsed in 14 hepatitis B patients with decompensated liver cirrhosis during lamivudine treatment due to the YMDD motif mutation. All 14 patients had positive HVBDNA and active hepatitis, and were evaluated as Child-Pugh Score C (CPS-C). The patients were treated with lamivudine 50 mg/d and adefovir dipivoxil 10 mg/d for 6 months. RESULTS: One patient signed off due to non-hypoxemic hyperlactacidemia; other 13 patients showed decreased serum HBVDNA. All patients had serum HBVDNA < or =10(5) copies/ml and 7 patients had HBVDNA < or =10(4) copies/ml. Six patients regained normal serum ALT level and Child-Pugh scores decreased in all patients. CONCLUSION: Adefovir dipivoxil has satisfied efficacy and safety in treatment of decompensated liver cirrhosis patients with YMDD motif mutation during lamivudine treatment.
