目的 观察拉米夫定和(或)阿德福韦酯治疗失代偿期乙型肝炎肝硬化3年疗效.方法 收集乙型肝炎肝硬化失代偿期患者68例,分为抗病毒治疗组和对照组,观察入组患者的临床症状、体征、生化指标、HBV DNA和Child-Pugh分级等变化情况.结果 随访治疗中,治疗组6个月后ALT、ALB和HBV DNA水平均较对照组有明显改善,12个月后TBil和Child-Pugh评分较对照组有明显改善,差异具有统计学意义(P<0.05);治疗组和对照组36个月生存率分别为62.5%和36.1%,差异具有统计学意义(P< 0.05);36个月后治疗组和对照组肝细胞癌发生率分别为3.1%和8.3%,差异无统计学意义.结论 拉米夫定和(或)阿德福韦酯治疗失代偿期乙型肝炎肝硬化,能够改善患者肝功能,延缓疾病进展,提高生存率. 相似文献

Objective To investigate the relationship between the single nucleotide polymorphisms (SNP) of programmed cell death-1 (PD-1) gene and early virologic response of interferon-α (IFN-α) in patients with chronic hepatitis B (CHB). Methods A total of 135 CHB patients were prospectively enrolled in this study. SNP of PD-1.1 and PD-1.2 genes were examined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in these patients.Then its relationship with early virologic response to IFN-α treatment was analyzed. The data were analyzed by x2 test. Results Among the 135 patients, 33 (24.4%) achieved early virologic response to IFN-α. There were 35, 77, and 23 patients with AA, AG, GG genotgpe of PD-1.1. The early virologic response was achived in 5(14.3%), 25(32.5%) and 3(13.0%) among patients with AA,AG, GG genotypes of PD-1.1, respectively. There were statistically different (x2 = 6. 258, P =0. 044). The subjects with AG genotype showed higher response rate than those with AA or GG genotypes (x2 = 6. 246, P= 0. 012). However, the early virologic response rates were not significant different among subjects with AA, AG or GG genotype of PD-1. 2 ( x2= 3.957, P= 0. 138).Conclusion SNP of PD-1.1 gene may be used as a marker to predict the early virologic response to IFN-α treatment in Chinese CHB patients. 相似文献
