目的探讨乙肝隐匿型感染(occult infection of HBV)在隐源性肝病中的感染率。方法采用PCR技术从健康献血人员与HBsAg阴性的隐源性肝病患者(包括肝硬化、肝癌、丙肝与病因不清肝炎)血清中检测HBV X DNA,统计并分析HBV在各组中的感染率。...目的探讨乙肝隐匿型感染(occult infection of HBV)在隐源性肝病中的感染率。方法采用PCR技术从健康献血人员与HBsAg阴性的隐源性肝病患者(包括肝硬化、肝癌、丙肝与病因不清肝炎)血清中检测HBV X DNA,统计并分析HBV在各组中的感染率。结果隐匿型HBV在健康人群中的感染率为5%,而在隐源性肝硬化、肝癌、丙肝与病因不清肝炎中的感染率分别为30%、20%、32%、7.4%。与健康人群相比,隐源性肝硬化、肝癌与丙肝患者的HBV感染率显著增加、但病因不清肝炎患者HBV感染率却无显著差异。研究还发现,肝硬化与肝癌患者的性别/HBV抗体的检出与HBV感染率的关系不大,但丙肝患者其HBV抗体的检出与HBV感染率有密切的联系。结论本研究小范围内统计了隐匿型HBV在隐源性肝病中的感染率,并证实HBV隐匿型感染在隐源性肝硬化、肝癌患者中与性别、HBV抗体检出没有关系,而在丙肝患者中其与乙肝血清抗体的检出相关。展开更多

It is recognized by two main characteristics: absence of HBsAg, and low viral replication. The previous two decades have witnessed a remarkable progress in our understanding of OBI and its clinical implications. Appropriate diagnostic techniques must be adopted. Sensitive HBV DNA amplification assay is the gold standard assay for detection of OBI. Viral as well as host factors are implicated in the pathogenesis of OBI. However, published data reporting the infectivity of OBI by transfusion are limited. Several aspects including OBI transmission, infectivity and its relation to the development of chronic liver diseases and hepatocellular carcinoma have to be resolved. The aim of the present review is to highlight recent data on OBI with a focus on its virological diagnosis and clinical outcome.展开更多
