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

目的探讨干扰素治疗慢性乙型肝炎出现HBsAg血清转换后再转为阳性对病情的影响。方法 5例慢性乙型肝炎患者在使用干扰素治疗发生HBsAg血清转换,而后再现HBsAg阳性的病史特点、临床表现以及治疗过程中的肝功能、HBV DNA和HBeAg等变化情况。结果 5例患者接受干扰素治疗时间为3~15个月,在治疗开始后3~18个月发生HBsAg转阴;3例HBeAg阳性患者在HBsAg转阴之前或同时出现HBeAg转阴,但未发生HBeAg/抗HBe血清转换;5例患者HBsAb持续存在6~18个月后消失,且HBsAg在同时或之后复阳;1例患者在治疗后30个月时HBV DNA为3.36×106copies/ml,ALT为98u/L,开始接受替比夫定治疗;1例患者在干扰素治疗过程中发生白癜风。结论干扰素治疗慢性乙型肝炎患者出现HBsAg血清转换后再转为阳性可能与患者未出现HBeAg血清学转换、治疗时间不够长或肝内存在HBV cccDNA等有关。 相似文献

干扰素-α治疗HBeAg阳性慢性乙型肝炎患者的疗效及影响因素分析 总被引:1,自引:0,他引:1
目的探讨HBeAg阳性慢性乙型肝炎(CHB)患者干扰素-α(IFN-α)疗效的影响因素。方法收集105例HBeAg阳性CHB患者,检测IFN-α治疗前及治疗12周时的ALT、HBV-DNA、HBsAg、HBsAb、HBeAg、HBeAb、HBcAb;分析年龄、性别、ALT基线水平、HBV-DNA基线水平对IFN-α疗效的影响。结果不同年龄段组间IFN-α疗效差异有统计学意义(P<0.05);ALT基线水平>120 U/L(<400 U/L),HBV-DNA基线水平<107拷贝/ml均能取得较好的疗效。结论 ALT基线水平、HBV-DNA基线水平、年龄可以作为预测IFN-α疗效的指标。 相似文献
