替比夫定治疗慢性乙型肝炎临床疗效及影响因素的研究

目的：观察替比夫定抗乙型肝炎病毒的疗效并评估影响疗效的因素。方法：采用替比夫定治疗200例慢性乙型肝炎患者,分别于治疗前及治疗后12、24、48周进行病毒学、血清学及生化学指标的检测,观察抗病毒疗效并评估影响疗效的因素。结果：替比夫定治疗48周,HBV DNA转阴率为85.5%,HBeAg血清转换率为26.76%,ALT复常率为76%,耐药率为3.5%;HBeAg阴性患者的HBV DNA转阴率高于HBeAg阳性患者（P〈0.05）;基线ALT〉5×ULN患者的HBV DNA转阴率、HBeAg血清学转换率均高于ALT2～5×ULN的患者（P〈0.05）;治疗24周后HBV DNA转阴的患者与未转阴患者相比,其48周HBV DNA转阴、ALT复常和HBeAg血清转换的比例明显增高（P〈0.05）。治疗48周过程中,43.5%患者曾出现肌酸激酶（CK）升高,无1例发生严重不良事件而停药。结论：替比夫定能显著抑制HBVDNA复制,使ALT复常,促进HBeAg血清转换,且耐药率较低,是一种安全有效的抗病毒药物。

Efficacy of telbivudine on patients with chronic hepatitis B and factors of predict efficacy

Objective:To investigate the efficciency of telbivudine on patients with chronic hepatitis B and evaluate the factors of can predict the efficacy.Methods:The virology,serology and biochemical indicators of 200 patients who received telbivudine for the treatment of chronic hepatitis B were detected and analysised before and at week 12,24 and 48 of the treatment,in order to get the predict efficacy factors of the treatment.Results:After 48 weeks of treatment,HBV DNA negative rate was 85.5%,HBeAg seroconversio...
