【摘要】 目的探讨乙型肝炎病毒(HBV)不同基因型及乙型肝炎e抗原(HBeAg)对聚乙二醇干扰素治疗慢性乙型肝炎(CHB)应答率的影响。方法采用聚合酶链反应-限制性片段长度多态性(PCR-RFLP) 方法,分析42例用聚乙二醇干扰素治疗的CHB患者基因型及HBeAg不同状态时对抗病毒治疗的影响。结果不同基因型对聚乙二醇干扰素的应笞率不同,B基因型的持续应答率为66.7%(12/18),C基因型持续应答率为27.3%(3/11)。HBeAg阴性患者的持续应答率为87.5%(7/8),HBeAg阳性患者为38.1%(8/21), P<0.05。结论HBV基因型及HBeAg的不同状态是预测聚乙二醇干扰素疗效的重要因素,且后者比前者的意义更大。更多还原

【Abstract】 Objective To study the effects of genotypes of HBV and HBeAg on the response to PEG-mterferon alpha (PEG-IFN) in chronic hepatitis B (CHB) patients. Methods PCR-RFLP and S gene sequencing were conducted in 42 CHB patients. Results The sustained response (SR) rates were 66.7% in genotype B and 27.3% in genotype C group. The P value was 0.039 by the Pearson Chi-square test, while it was 0.06 by the Fisher’s exact test. The results suggested a trend that patients with genotype B HBV compared to genotype C had better SR to PEG-IFN therapy, although the difference was not significant. Results also showed that SR rate in patients with HBeAg-negative CHB (7/8 87.5%) was significantly higher than that in HBe+ CHB patients (8/21 38.1%, P < 0.05). Conclusion Our results indicate that HBV genotype and HBeAg, especially the later, are main factors for predicting PEG-IFN therapy response in CHB patients.更多还原
