Response to long-term lamivudine treatment in patients infected with hepatitis B virus genotypes A, B, and C

Response to lamivudine treatment longer than 1 year was compared in 15 patients persistently infected with hepatitis B virus (HBV) genotype A, 38 with genotype B, and 449 with genotype C. Patients with genotype A were younger (median age 37 [range 24–49] vs. 47 [24–67] or 44 [18–73], P = 0.015), pos...

During lamivudine, YMDD mutants (89% vs. 53% or 42%, P = 0.0001) and breakthrough hepatitis developed more often (47% vs. 21% or 29%, P = 0.023) in patients with genotype A than B or C. YMDD mutants elicited more frequently in patients with genotype A than B or C who were positive (82% [9/11] vs. 25% [2/8] or 48% [117/245], P = 0.037) or negative for HBeAg (75% [3/4] vs. 30% [9/30] or 33% [68/204], P = 0.003). HBeAg (hazard ratio 2.1 [95% confidence interval 1.53–2.92], P < 0.001) and genotype A (2.78 [1.08–7.12], P = 0.034) enhanced the emergence of YMDD mutants by the Cox proportional hazard model. The risk for breakthrough hepatitis was increased by the baseline alanine aminotransferase level <500 IU/L (2.56 [1.82–5.50], P = 0.018), HBeAg (2.11 [1.40–3.16], P < 0.001), cirrhosis (1.92 [1.24–2.97], P = 0.004) and HBV DNA ≥8.0 LGE/ml (1.57 [1.04–2.36], P = 0.03); it was influenced by genotypes only in patients with HBeAg.
