Background : Long-term effect of YMDD mutations on liver histology in Chinese hepatitis B patients is unknown.Aim : To examine the effect of prolonged lamivudine treatment on liver histology in Chinese patients with and without YMDD mutations.Methods : Liver histology was assessed in 85 patients on long-term lamivudine at baseline and year 1, and at year 3 for 25 patients.Results : Comparing patients with and without YMDD mutations at year 1, the former had higher baseline median necroinflammatory (11 vs. six respectively, P = 0.014) and fibrosis scores (three vs. one respectively, P = 0.001). The proportion of patients with improvement in necroinflammation and worsening of fibrosis was comparable for patients with and without YMDD mutations at year 1 (57.1%, 14.3% vs. 55%, 15% respectively) and year 3 (57.9%, 26.3% vs. 50%, 16.7% respectively). Comparing the histology at year 1 and 3, more patients with YMDD mutations developing after year 1 had worsening of necroinflammation than patients with persistent YMDD wild type (53.8% vs. 25% respectively).Conclusions : Patients who developed YMDD mutations had higher baseline histological scores. With YMDD mutations, the liver histology became less favourable after 3 years than at the first year, although there was still improvement when compared with that at baseline.
