Traditionally, when antibody to the Hepatitis B core antigen (anti-HBc) and antibody to the Hepatitis B surface antigen (anti-HBs) are positive, the donor is considered suitable. However, the literature contains cases with this profile and circulating hepatitis B virus DNA. The aim of the study is to analyze the incidence of occult hepatitis B virus infection (OBI). Retrospective data were evaluated for deceased tissue donors in ten Tissue Establishments (Spain) during 2017. The data included demographic data and the serological markers for hepatitis B that each tissue establishment performed. A total number of 1933 tissue donors were evaluated. A total of 180 donors were excluded: 6 (0.3%) with Hepatitis B surface antigen (HBs positive), and 174 in which DNA testing was not performed. Anti-HBc was positive in 175 donors (10%), in which anti-HBs was negative in 30 (17.1%) and positive in 145 (82.9%). In total, 27 donors with DNA positive (1.5%) were found, of which 3 of 117 donors (1.7%) showed anti-HBc negative and anti-HBs positive (> 10 IU/ml), 4 of 30 donors (13.3%) showed anti-HBc positive and anti-HBs negative and 20 of 145 donors (13.8%) showed both anti-HBc and anti-HBs positive. The highest probability of finding DNA occurs when anti-HBc is positive, regardless of the presence of anti-HBs. In our study, the probability of OBI was 1.5%. The classic concept that when anti-HBc and anti-HBs are positive (even with a titer of over 100 IU/ml) the donor can be accepted should, therefore, be reconsidered, and DNA testing should be mandatory.

组织供体隐匿性乙型肝炎感染的评估:西班牙的多中心分析。

传统上,当抗乙肝核心抗原的抗体(抗HBc)和抗乙肝表面抗原的抗体(抗HBs)呈阳性时,供体被认为是合适的。但是,文献中包含具有这种特征和正在传播的乙型肝炎病毒DNA的病例。该研究的目的是分析隐匿性乙型肝炎病毒感染(OBI)的发生率。在2017年期间,对十个组织机构(西班牙)中已故组织捐赠者的回顾性数据进行了评估。数据包括每个组织机构执行的人口统计学数据和乙型肝炎血清学标志物。评价了总共1933个组织供体。总共排除了180个供体:6个(0.3%)的乙型肝炎表面抗原(HBs阳性)和174个未进行DNA检测的供体。175位捐献者(10%)的抗HBc阳性,其中抗HBs阴性的有30(17.1%),阳性的有145(82.9%)。总共发现了27个DNA阳性的供体(1.5%),其中117个供体中的3个(1.7%)显示抗HBc阴性和抗HBs阳性(> 10 IU / ml),30个供体中有4个(13.3%) )显示抗HBc阳性和抗HBs阴性,145个捐献者中有20个(13.8%)均显示抗HBc和抗HBs阳性。无论抗-HBs是否存在,当抗-HBc阳性时,发现DNA的可能性最高。在我们的研究中,OBI的可能性为1.5%。因此,应重新考虑经典的概念,即抗HBc和抗HBs呈阳性(甚至滴度超过100 IU / ml)时,可以接受供体,并且必须进行DNA检测。在117个捐献者中,有3个(1.7%)显示抗HBc阴性和抗HBs阳性(> 10 IU / ml),在30个捐献者中有4个(13.3%)显示出抗HBc阳性和抗HBs阴性,在145个捐献者中有20个供体(13.8%)显示抗-HBc和抗-HBs均为阳性。无论抗-HBs是否存在,当抗-HBc阳性时,发现DNA的可能性最高。在我们的研究中,OBI的可能性为1.5%。因此,应重新考虑经典的概念,即抗HBc和抗HBs呈阳性(甚至滴度超过100 IU / ml)时,可以接受供体,并且必须进行DNA检测。在117个捐献者中,有3个(1.7%)显示抗HBc阴性和抗HBs阳性(> 10 IU / ml),在30个捐献者中有4个(13.3%)显示出抗HBc阳性和抗HBs阴性,在145个捐献者中有20个供体(13.8%)显示抗-HBc和抗-HBs均为阳性。无论抗-HBs是否存在,当抗-HBc阳性时,发现DNA的可能性最高。在我们的研究中,OBI的可能性为1.5%。因此,应重新考虑经典的概念,即抗HBc和抗HBs呈阳性(甚至滴度超过100 IU / ml)时,可以接受供体,并且必须进行DNA检测。无论抗-HBs是否存在,当抗-HBc阳性时,发现DNA的可能性最高。在我们的研究中,OBI的可能性为1.5%。因此,应重新考虑经典的概念,即抗HBc和抗HBs呈阳性(甚至滴度超过100 IU / ml)时,可以接受供体,并且必须进行DNA检测。无论抗-HBs是否存在,当抗-HBc阳性时,发现DNA的可能性最高。在我们的研究中,OBI的可能性为1.5%。因此,应重新考虑经典的概念,即抗HBc和抗HBs呈阳性(甚至滴度超过100 IU / ml)时,可以接受供体,并且必须进行DNA检测。
