36名HBsAg无症状携带者血液的受血者调查结果。受血前抗-HBs阳性为56.2％。受血后2人(5.5％)发生乙型肝炎,4人(11.1％)出现单项SGPT异常,抗-HBs转阳率83.3％(10/12)。受血者中,乙肝发病率与东南亚地区相似,低于西欧、北美,但乙肝感染率较高。HBsAg无症状携带者血液传染性与其滴度有关,滴度愈高传染性愈强。受血前HBsAg阳性的3名受血者,受血后HBsAg滴度无明显变化。受血者中无新的HBsAg携带者发生。
Blood test results for 36 HBsAg asymptomatic carriers. Pre-blood anti-HBs positive was 56.2%. Hepatitis B occurred in 2 patients (5.5%) and single abnormality of SGPT in 4 patients (11.1%). The positive rate of anti-HBs was 83.3% (10/12). Among the recipients, the incidence of hepatitis B is similar to that in Southeast Asia, but lower than that in Western Europe and North America, but the rate of hepatitis B infection is higher. Blood transfusion of HBsAg asymptomatic carriers is related to their titer, and the higher the titer, the more infectious. Before the blood HBsAg positive three recipients, HBsAg titer did not change significantly after receiving blood. No new HBsAg carriers occur in recipients.
