江苏省宜兴地区丙型肝炎病毒F蛋白抗体检测

目的检测江苏省宜兴地区丙型肝炎（丙肝）患者血清丙肝病毒（HCV）-F抗体及其分布。方法利用基因重组获得的HCV—F／GST蛋白作为抗原，包被酶联反应板，ELISA间接法检测120例丙肝患者、15例乙肝患者、3例戊肝患者及10份正常人血清HCV—F抗体，结合丙肝患者的临床资料及疾病特征，统计分析HCV—F抗体的分布情况及与HCV感染的关系。结果120例丙肝患者血清HCV—F抗体阳性82例，阳性率68％，而15例乙肝、3例戊肝患者及10份正常人血清标本均未检出阳性；资料分析显示HCV—F抗体阳性率与HCV患者年龄、临床类型之间差异有统计学意义，51岁以上年龄组的HCV—F抗体阳性率是20～50岁组的6．675倍（95％CI：2．407～19．071），并且随着病程进展，阳性率也随之增高（OR=2．749，95％CI：1．470～5．141）。结论江苏省宜兴地区HCV感染者血清中存在HCV—F抗体，并可能与病程相关。

Detection of serum anti-F antibody in hepatitis C virus infected patients

OBJECTIVE: To assess the prevalence of serum anti-F in patients with hepatitis C virus (HCV) infection and the distribution of anti-F. METHODS: The recombinant protein (HCV-F/GST) was coated onto micro titer plates as antigen. Sera of 120 patients with hepatitis C virus infection, 15 patients with hepatitis B, 3 patients with hepatitis E and 10 normal sera were tested by indirect ELISA for detecting anti-F. RESULTS: 82 samples out of the 120 (68%) HCV infected patients exhibited a positive anti-F reaction, showing significant difference from the controls with no HCV infection (P < 0.01). Data from logistic analysis showed that the positive rate of anti-F was higher in patients over 50 year olds (OR = 6.675, 95% CI: 2.407-19.071). Patients of midrange, severe phase and hepatic cirrhosis had higher rate than the others (OR = 2.749, 95% CI: 1.470-5.141). CONCLUSION: Prevalence and distribution of anti-F in Yixing hepatitis C patients was reported and which might be related to the progression of HCV infection.
