目的:通过检测干扰素抗体、HCV 基因分型、治疗前后血清 HCV-RNA 量及淋巴细胞亚群,探讨干扰素疗效的预测因素.方法:ELISA 方法检测干扰素抗体,抗病毒中和生物鉴定法进行干扰素中和抗体检测.用 MTT 检测干扰素中和抗体的滴度.进行 HCV 基因分型及血清 HCV-RNA 定量检测.采用 APAAP 免疫桥联酶标法检测 T 淋巴细胞亚群.结果:(1)HCV-Ⅲ型感染者完全应答率较 HCV-Ⅱ型高,P<0.05.(2)完全应答组治疗前血清 HCV-RNA 量明显低于部分应答和无应答组.(3)部分应答组干扰素抗体阳性率明显高于完全应答组,P<0.05.中和抗体对干扰素疗效的影响与抗体的滴度有关,抗体滴度高干扰素疗效差.(4)各组间淋巴细胞亚群变化无统计学差异.结论:(1)治疗前血清 HCV-RNA 低水平是对干扰素治疗产生完全应答的一个重要的预测指标.(2)HCV-Ⅲ型患者对干扰素治疗的完全应答率明显高于 HCV-Ⅱ型.但可能受血清 HCV-RNA 水平的影响.(3)干扰素抗体,特别是中和抗体是影响干扰素疗效的因素之一,治疗过程中检测干扰素抗体是预测干扰素疗效的指标之一.(4)外周血淋巴细胞亚群不能作为预测干扰素疗效的指标.
