Abstract

A study was undertaken to assess the state of hepatitis B virus infection in a group of asymptomatic hepatitis B surface antigen (HBsAg) carriers. This study confirmed that the presence of hepatitis B e antigen (HBeAg) in serum was closely associated with serum HBsAg-specific deoxyribonucleic acid polymerase activity, hepatitis B core antigen (HBcAg) in serum and liver cell nuclei, and a histological picture of chronic hepatitis. No HBsAg-specific deoxyribonucleic acid polymerase activity or HBcAg was detected in highly concentrated anti-HBe-positive sera. In addition, liver biopsy specimens from carriers with anti-HBe were negative for HbcAg by immunofluorescence, and the liver histology was either normal or revealed only fatty changes. These data indicate that the anti-HBe-positive sera contained either no Dane particles or, if present, at least a 500-fold-lower concentration of Dane particles than that found in HBeAg-positive sera.

摘要

开展了一项研究,以评估一组无症状乙肝表面抗原(HBsAg)携带者的乙肝病毒感染状况。该研究证实,血清中乙肝e抗原(HBeAg)的存在与血清HBsAg特异性脱氧核糖核酸聚合酶活性、血清和肝细胞核中的乙肝核心抗原(HBcAg)以及慢性肝炎的组织学表现密切相关。在高浓度抗-HBe阳性血清中未检测到HBsAg特异性脱氧核糖核酸聚合酶活性或HBcAg。此外,抗-HBe携带者的肝活检标本经免疫荧光检测HbcAg为阴性,肝脏组织学要么正常,要么仅显示脂肪变性。这些数据表明,抗-HBe阳性血清中要么不含 Dane 颗粒,要么即便存在,其 Dane 颗粒浓度至少比 HBeAg 阳性血清中低500倍。
