【摘要】 目的 :探讨干扰素抗体与干扰素治疗慢性丙型肝炎临床疗效的关系。方法 :用酶免疫法 (EIA)检测 4 1例应用干扰素治疗的慢性丙型肝炎患者治疗前及治疗不同时期血清中的干扰素总抗体 ,同时应用抗病毒中和生物鉴定法 (ANB)检测干扰素中和抗体及其滴度。结果 :应答伴反跳组干扰素中和抗体及总抗体的阳性率明显高于完全应答组 (P <0 .0 5 ) ,而完全应答组和无应答组间无显著性差异 (P >0 .0 5 )。干扰素中和抗体滴度与患者血清ALT水平间存在相关关系 ,且NA滴度 <1:80 0患者的完全应答率明显高于NA滴度≥ 1:80 0的患者 (P <0 .0 5 )。结论 :干扰素抗体的产生可能是影响干扰素临床疗效的因素之一 ,以中和抗体对疗效的影响为主 ,中和抗体滴度高 ,干扰素的疗效差。干扰素中和抗体的产生可能是临床应用干扰素治疗慢性丙型肝炎患者出现反跳的原因之一。目的 :探讨干扰素抗体与干扰素治疗慢性丙型肝炎临床疗效的关系。方法 :用酶免疫法 (EIA)检测 4 1例应用干扰素治疗的慢性丙型肝炎患者治疗前及治疗不同时期血清中的干扰素总抗体 ,同时应用抗病毒中和生物鉴定法 (ANB)检测干扰素中和抗体及其滴度。结果 :应答伴反跳组干扰素中和抗体及总抗体的阳性率明显高于完全应答组 (P <0 .0 5 ) ,而完全应答组和无应答组间无显?更多还原

【Abstract】 Objective: The aim of this study was to evaluate the relationship between anti-interferon antibodies (anti-IFN Ab) and the therapeutic effect of interferon (IFN) in patients with chronic hepatitis C. Methods: The total anti-IFN Ab and neutralizing antibodies (NA) were detected by enzyme immunol assay (EIA) and antiviral neutralizing bioassay (ANB) respectively in sera of 41 patients with chronic hepatitis C before the treatment and in different periods during the treatment with IFN- α2b. Results: The positive rates of anti-IFN Ab and NA were significantly higher in group of responders with breakthrough than of complete response (P<0.05); however ,there was no statistic difference between no response and complete response gorup (P>0.05). There was a positive correlation between the titer of NA and the level of ALT. Conclusion: The development of anti-IFN Ab may be one of the factors affecting the therapeutic effect of IFN- α 2b , especially NA. The NA may be one of the reasons for breakthrough.更多还原
