350例病毒性肝炎患者检测HBV-DNA与HBV血清学标志物相关性研究

采用ＰＣＲ技术对３５０例各型病毒性肝炎进行检测，旨在研究血清ＨＢＶ－ＤＮＡ与血清ＨＢＶ－Ｍ之间的相关性，以确定ＰＣＲ法检测ＨＢＶ－ＤＮＡ的临床意义。并以ＨＢＶ－ＤＮＡ为依据进一步考察ＨＢＶ－Ｍ的临床价值。结果显示：在ＨＢｓＡｇ（＋）、ＨＢｅＡｇ（＋）、抗－ＨＢｃ（＋）病例中ＨＢＶ－ＤＮＡ（＋）者１０２例（９０．２７％），说明ＨＢｅＡｇ基本可反应病毒处于复制状态；在１３７例ＨＢｅＡｇ（－）／抗－ＨＢｅ（＋）中，ＨＢＶ－ＤＮＡ（＋）为６８例（４９．６３％），表明病毒活动并未终止；在抗－ＨＢｓ（＋）１４例中，ＨＢＶ－ＤＮＡ（＋）２例（１４．２９％），说明抗－ＨＢｓ出现后仍然可有ＨＢＶ复制；在ＨＢＶ－Ｍ均阴性的８５例中，ＨＢＶ－ＤＮＡ（＋）２３例（２７．０６％），说明不能单纯依靠ＨＢＶ－Ｍ检测来诊断乙肝，需定期查ＨＢＶ－ＤＮＡ或肝活体组织检查ＨＢＶ－ＤＮＡ、ＨＢｓＡｇ及ＨＢｃＡｇ。

Studies on correlation between HBV-DNA and HBV-M in the serum of 350 patients with virus hepatitis

HBV-DNA was detected by PCR in serum of 350 patients with viral hepatitis in order to study the relationship between HBV-DNA and HBV-Marker for determining the clinical significance of detecting HBV-DNA,and diagnostic value of HBV-Marker was evaluated on the basis of HBV-DNA detection.The results showed that 90.27% of 102 HBV-DNA positive cases were positive for HBsAg and HBeAg,and 49.63% of 137 Anti-HBe positive cases but negative HBeAg were found to be HBV-DNA positive suggesting that HBV is still in replication.HBV-DNA was found in serum of 2 cases (14.29%) of 14 Anti-HBs positive patients, suggesting that HBV are actively replicated.HBV-DNA was detected in 23 HBV-Marker negative Cases (27.06%).The results suggest that diagnosis of viral hepatitis cannot be made by HBV-Marker alone and it is judicious to utilize supplemental assay for HBV-DNA to document HBV infection. 
