J Hepatol:HEV-RNA阳性的血制品,输入免疫抑制者,有相关感染的风险

2018-03-25 MedSci MedSci原创

德国北部的献血者中,可以检测到HEV-病毒血症的持续存在,从而导致接受者发生严重和致命并发症。吃生猪肉是感染HEV的相关风险。

研究背景:最近,在英国和荷兰已经实施血液制品检测戊型肝炎病毒(HEV)。输血传播的HEV感染的相关性在欧洲仍有争议。

研究方法:2016年10月至2017年5月,医疗中心Hamburg-Eppendorf的所有血液捐献都通过PCR技术进行HEV-RNA检测。对反应性样品进行了复测。此外,还对先前阳性捐献者的标本进行了检测,以确定HEV-病毒血症的持续时间。HEV-RNA阳性献血者和对照组被要求回答一份问卷。

研究结果:在18737例样本中,23例样本呈现HEV-RNA阳性。只有两名捐献者(8.7%)在捐赠时肝脏转氨酶(ALT: 192 U/l和101 U/l)升高。对所有HEV-RNA阳性的捐献者的回顾性分析显示,4个无症状的捐献者HEV-病毒血症持续时间多达3个月,最长HEV-病毒血症持续时间超过4个月。14例HEV-RNA阳性血液制品被输给12个免疫缺陷型和2个免疫能力强的患者。这些血液制品的一个接受者发生了致命的急性慢性肝功能衰竭合并假单胞菌血症。调查问卷显示,HEV-RNA阳性捐赠者相比对照组患者,食用生猪肉更频繁(p=0.01)。在两个供者中,未煮熟的猪肝被确认为感染源。

研究结论:德国北部的献血者中,可以检测到HEV-病毒血症的持续存在,从而导致接受者发生严重和致命并发症。吃生猪肉是感染HEV的相关风险。
