献血员血清抗─HCV水平及其感染因素调查

Study on prevalence of anti-HCV and its infection factors of blood donors

对１６７名职业献血员进行了献血前筛选，结果抗ＨＣＶ阳性检出率达１７．６７％（１１９／６７０）．ＡＬＴ异常和ＨＢｓＡｇ阳性者抗－ＨＣＶ阳性检出率分别为６６．６７％和２９．２％，高于ＡＬＴ正常和ＨＢｓＡｇ阴性者（１４．Ｏ％和１６．９％）。不同年龄、性别的献血员ＨＣＶ感染无差异。运用１：１配对的病例对照研究方法对９７对抗－ＨＣＶ阳性和阴性的献血员进一步的调查发现：有献血浆、肝炎、饮酒、针灸史及ＡＬＴ异常、ＨＢｓＡｇ阳性的献血员感染ＨＣＶ的危险性分别是无上述因素的５４．１９，２．５３，１．８８，６．０８和４．５９，２．５３倍，献血浆成为献血员感染ＨＶＣ的第一高危因素（ＯＲ＝５４．１９）；且献血浆（或全血）次数越多、献血时间越长，其感染ＨＣＶ的危险性越大，从而呈现明显的“剂量－效应”关系。

professional blood donors were screened, the prevalence of anti-HCV was 17. 67%, while that of whose abnormal alanine transferase(ALT) levels and HBsAg positive was 66. 67% and 29. 2% respectively, significantly higher than that of whose normal ALT levels and HBsAg negtion (14. 0% and 16. 9%), the rate infected HCV wasn’t sinificant different in age and sex. The further result revealed that those who had history of plasma donation, hepatitis. drinking and acupuncture plasma donation, were risker to infect HCV than those who had not. The possibility of being infected increased with the increase and number of donation.
