有偿献血员中艾滋病病毒、乙型肝炎和丙型肝炎病毒感染状况的研究

目的 探讨有偿献血员艾滋病病毒(HIV)、丙型肝炎(丙肝)病毒(HCV)、乙型肝炎(乙肝)病毒(HBV)感染的特点。方法61份HIV阳性献血员及89份HIV阴性献血员的血清,经酶联免疫吸附试验(ELISA)检测HCV抗体(抗-HCV)及HBV血清学标志物,比较两组人群的HCV、HBV及HCV/HBV感染情况。结果HIV阳性献血员的抗-HCV阳性率为70.49％。乙肝病毒表面抗原(HBsAg)与抗体(抗-HBs)、乙肝病毒e抗原(HBeAg)与抗体(抗-HBe)、乙肝病毒核心抗体(抗-HBc)和HBV的阳性率分别为8.20％、29.51％、3.28％、44.26％、11.4896、47.54％;而HIV阴性献血员的抗-HCV阳性率为19.10％,HBsAg、抗-HBs、HBeAg、抗-HBe、抗-HBc、HBV的阳性率分别为2.25％、38.20％、1.12％、47.19％、6.74％、47.19％。经统计学分析,两组人群的HCV、HCV/HBV感染率的差异有显著的统计学意义,而HBV血清学标志物则无显著性差异。结论 与HIV阴性献血员相比。HIV阳性献血员的HCV感染率很高,而HBV血清学标志物则无显著性差异。对献血员进行HBV检测而未检测HIV、HCV造成的选择偏倚,可能是中国中部一些省份HIV感染者HCV感染率高而HBV感染并不相应增高这一现象的原因之一。

Study on the Serological Status of HCV and HBV among HIV Infected Blood Donors

Objective To study the serological characteristics of HCV and HBV infections among HIV infected blood donors. Methods Antibodies to HCV and serological markers of HBV infection were detected by ELISA among 61 cases of HIV infected blood donors and 89 cases of HIV negative ones.Result The prevalence rate of HCV infection was 70.49% in the HIV infected blood donors and 19.10% in the HIV negative ones.The prevalence of HCV infection and HCV/HBV co-infections was significantly different between HIV infected blood donors and HIV negative ones, while there was no significant difference in the serological markers of HBV. Conclusinon Compared to HIV negative ones, HIV infected blood donors had a much higher rate of HCV infection. This can be partly attributed to the bias that blood donors were screened by detecting HBV serological markers without detecting antibodies to HCV and HIV.
