The long-term effectiveness and safety of lamivudine in patients with decompensated hepatitis B virus-related cirrhosis are still not clear. The present study attempted to describe the clinical outcomes of lamivudine therapy in these special patients over three years.
This study was a retrospective, controlled cohort study which involved 153 patients with decompensated hepatitis B virus-related cirrhosis. Of these, 86 patients received lamivudine 100 mg daily accompanied with general internal treatment, and the other 67 were given general internal treatment only. Significant clinical responses were recorded after years of antiviral treatment.
The patients in both groups were matched in terms of age, sex and laboratory results at baseline. After years of therapy, the Child-Pugh-Turcotte scores and laboratory values of the patients receiving lamivudine were remarkably improved compared to the patients in the control group. The mortality rate and the incidence of cirrhosis-related complications were much lower in the lamivudine group than in the control group. Genotypic resistance tyrosine, methionine, aspartate, aspartate mutations developed in 26.7 percent of the patients during 3-year lamivudine treatment, and cirrhosis-related death and the hepatocellular carcinoma were more likely to occur in patients with these mutations than in the other patients who were treated with lamivudine.
Continuous long-term lamivudine treatment in patients with decompensated hepatitis B virus-related cirrhosis delays clinical progression, and significantly improves hepatic function and prognosis. However, the use of a retrospective control cohort precludes drawing definitive conclusions.
拉米夫定治疗失代偿期乙型肝炎病毒相关肝硬化患者的长期疗效和安全性尚不清楚。本研究旨在描述拉米夫定治疗该类特殊患者 3 年以上的临床转归。
本研究为回顾性对照队列研究,共纳入 153 例失代偿期乙型肝炎病毒相关肝硬化患者。其中 86 例患者接受拉米夫定 100mg/d 联合内科综合治疗,67 例患者仅接受内科综合治疗。抗病毒治疗数年后观察其临床应答情况。
两组患者在年龄、性别和基线实验室检查结果方面相匹配。经过多年的治疗,拉米夫定组的 Child-Pugh-Turcotte 评分和实验室检查值明显优于对照组。拉米夫定组的病死率和肝硬化相关并发症发生率均明显低于对照组。在拉米夫定治疗 3 年期间,26.7%的患者出现了耐药相关的酪氨酸、蛋氨酸、天冬氨酸、天冬氨酸突变,这些突变患者发生肝硬化相关死亡和肝细胞癌的风险高于未发生突变的患者。
长期持续应用拉米夫定治疗失代偿期乙型肝炎病毒相关肝硬化可延缓疾病进展,明显改善肝功能和预后。但由于本研究采用回顾性对照队列设计,因此无法得出确切结论。
