In this paper, we studied the usefulness of polymerase chain reaction (PCR) in HDV-RNA detection. Using serial dilutions of serum samples of known concentrations of HDV-RNA, PCR was 10,000-times more sensitive than slot-blot hybridization. PCR was used for the detection of HDV-RNA in 33 serum samples negative to HDV-RNA by conventional slot-blot hybridization. HDV-RNA was detected in 18/33 (54%) of the samples included in this study using PCR. When positivity to a viral genome was related to other viral replication markers, it was found that among the 18 patients positive to the viral genome, 13 (72%) had hepatitis delta antigen in the liver, and five (28%) were negative. In conclusion, HDV-RNA detection by gene amplification is 10,000-times more sensitive than slot-blot hybridization, and allows the detection of viral replication in patients without other viral replication markers.
在本文中,我们研究了聚合酶链反应(PCR)在丁型肝炎病毒RNA(HDV-RNA)检测中的实用性。通过对已知HDV-RNA浓度的血清样本进行系列稀释,PCR的灵敏度比斑点杂交高10000倍。PCR用于检测33份经传统斑点杂交检测HDV-RNA呈阴性的血清样本中的HDV-RNA。在本研究纳入的样本中,使用PCR在18/33(54%)的样本中检测到了HDV-RNA。当病毒基因组阳性与其他病毒复制标志物相关时,发现在18例病毒基因组阳性的患者中,13例(72%)肝脏中有丁型肝炎抗原,5例(28%)为阴性。总之,通过基因扩增检测HDV-RNA的灵敏度比斑点杂交高10000倍,并且能够在没有其他病毒复制标志物的患者中检测到病毒复制。
