目的 探讨乙型肝炎病毒（HBV）表面抗原（HBsAg）阳性肝硬化患者血清中HBV前S1抗原(前S1抗原)、HBV e抗原（HBeAg）及HBV核酸定量检测（HBV DNA）相关性。 方法 2008年7月－2011年5月对97例HBsAg阳性肝硬化住院患者和50份HBsAg阴性的健康体检者血清进行前S1抗原、HBV血清标志物检测及实时荧光定量PCR检测HBV DNA结果进行分析。 结果 97份HBsAg阳性肝硬化患者血清中，前S1抗原、HBeAg及HBV DNA阳性率分别为53.6%（52/97）、22.7%（22/97）及61.8%（60/97）。22例HBeAg阳性血清中，前S1抗原阳性18例（81.8%）， HBV DNA阳性20例（90.9%)。75例HBeAg阴性血清中，前S1抗原阳性34例（45.3%），HBV DNA阳性40例（53.3%），两者的前S1抗原与HBV DNA结果间都具有很好的相关性。HBV DNA含量与前S1抗原及HBeAg阳性结果显示：HBsAg阳性的肝硬化患者血清中HBV DNA阴性率为38.1%（含量＜103 copies/mL），而阳性检出率HBV DNA含量主要集中在103～105 copies/mL，占81.7%（49/60），HBV DNA含量＞105 copies/mL占18.3%（11/60）。 结论 HBsAg阳性的肝硬化患者血清中主要以HBV非HBeAg阳性血清学模式为主，HBV DNA阳性检出率的含量主要集中在103～105 copies/mL。前S1抗原在HBeAg阳性血清中与其含有HBsAg病毒及HBeAg阳性患者具有很好的相关性，而在HBeAg阴性血清中存在着差异。Objective To study the correlation among Pre-S1 antigen, HBeAg and HBV DNA results in patients with HBsAg-positive liver cirrhosis. Methods We retrospectively analyzed the serum pre-S1-antigen, HBV serum markers and real-time quantitative PCR HBV DNA results in 97 patients with HBsAg-positive liver cirrhosis and 50 HBsAg-negative healthy volunteers in our hospital from July 2008 to May 2011. Results Among the 97 samples of HBsAg-positive liver cirrhosis patients’ serum, the positive rates of Pre-S1 antigen, HBeAg and HBV DNA were 53.6% (52/97), 22.7% (22/97) and 61.8% (60/97), respectively. In the 22 samples of HBeAg-positive serum, the number of positive pre-S1 antigen and HBV DNA was 18 (81.8%) and 20, respectively. In the 75 samples of negative HBeAg serum, the number of positive pre-S1 antigen and HBV DNA was 34 (45.3%) and 40 (53.3%) respectively. The pre-S1 antigen was correlated well with HBV DNA results in both the two groups. HBV DNA level, pre-S1 antigen and HBeAg-positive results showed that the serum HBV DNA negative rate of HBsAg-positive patients with cirrhosis was 38.1% (＜103 copies/mL), while the positive rate of HBV DNA level was mainly concentrated at 103~105 copies/mL, accounting for 81.7% (49/60), and HBV DNA level over 105 copies/mLaccounted for only 18.3% (11/60). Conclusions HBsAg-positive patients with cirrhosis mainly have a serum non-HBeAg-positive HBV serology pattern, and HBV DNA positive rate of the content is mainly concentrated at 103~105 copies/mL. There is a good correlation between pre-S1 antigen in HBeAg-positive serum and patients with HBsAg virus or positive HBeAg, while for Pre-S1 antigen in HBeAg-negative serum, it is quite different.
ObjectiveTo evaluate the relationship between hepatitis B virus (HBV) preS1 antigen and the virus replication index human hepatitis B e antigen (HBeAg) and liver function. MethodsA total of 310 cases of serum samples from patients with chronic HBV treated in our hospital between May and July 2012 were examined and studied. HBV preS1 antigen was detected by ELISA; HBeAg was detected by the Architect i2000 system; and alanine transaminase (ALT) was detected by kinetic method. ResultsThe detection rate of HBV preS1 antigen was higher in HBeAg positive group. HBV preS1 antigen was correlated with HBeAg which was an index of virus replication. HBV preS1 antigen was correlated with ALT levels. ConclusionThe levels of HBV preS1 antigen may reflect the replication of HBV and the reactiveness condition of chronic hepatitis.
