The hepatitis delta virus (HDV) causes the most aggressive form of chronic viral hepatitis. As HDV replication requires hepatitis B virus (HBV), HDV screening is limited to HBsAg+ carriers. To date, individuals with HDV-antibodies and markers of resolved hepatitis B are considered cured. However, a subset shows elevated liver enzymes and hepatic fibrosis. Could they represent HBsAg-seronegative occult HDV infections?
We tested for HDV-antibodies 406 individuals with markers of past HBV exposure.
Overall, 20 (4.9%) were reactive for HDV-antibodies. All were negative for serum HDV-RNA, including four with elevated liver enzymes.
These results support the current policy of screening for hepatitis delta only in HBsAg+ individuals.
丁型肝炎病毒(HDV)可引发最具侵袭性的慢性病毒性肝炎。由于HDV复制需要乙型肝炎病毒(HBV),HDV筛查仅限于HBsAg阳性携带者。迄今为止,具有HDV抗体且有乙型肝炎康复标志物的个体被认为已治愈。然而,有一部分人肝酶升高且存在肝纤维化。他们是否代表HBsAg血清学阴性隐匿性HDV感染?
我们对406名有既往HBV暴露标志物的个体进行了HDV抗体检测。
总体而言,20名(4.9%)个体HDV抗体呈阳性反应。所有个体血清HDV-RNA均为阴性,其中4名肝酶升高。
这些结果支持目前仅对HBsAg阳性个体进行丁型肝炎筛查的政策。
