Relativity among PreS1-antigen,HBV Markers and HBV-DNA / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study the relativity among PreS1-Antigen,HBV markers and HBV-DNA. METHODS The HBV markers,PreS1-antigen and HBV-DNA were determined by ELISA and PCR in 102 patients with chronic hepatitis B and 73 healthy persons. RESULTS Among 102 patients with chronic hepatitis B,the concordance rate of PreS1-antigen and HBeAg with HBV-DNA was 70.6% and 75.5%.The sensitivity of PreS1 was better than HBeAg but the specificity was contrary.It represented some patients with HBeAg(-) still had viral replication.On the increase in the level of HBV-DNA,the positive rates of PreS1-antigen and HBV markers increased. CONCLUSIONS The detection of PreS1-antigen can well reflect the HBV replication.The synchronous dynamic detection of PreS1-Antigen,HBV markers and HBV-DNA has its important clinical meaning.
