目的 探討乙型肝炎病毒（HBV）表面抗原（HBsAg）陽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核酸定量檢測（HBV DNA）相關性。 方法 2008年7月－2011年5月對97例HBsAg陽性肝硬化住院患者和50份HBsAg陰性的健康體檢者血清進行前S1抗原、HBV血清標志物檢測及實時熒光定量PCR檢測HBV DNA結果進行分析。 結果 97份HBsAg陽性肝硬化患者血清中，前S1抗原、HBeAg及HBV DNA陽性率分別為53.6%（52/97）、22.7%（22/97）及61.8%（60/97）。22例HBeAg陽性血清中，前S1抗原陽性18例（81.8%）， HBV DNA陽性20例（90.9%)。75例HBeAg陰性血清中，前S1抗原陽性34例（45.3%），HBV DNA陽性40例（53.3%），兩者的前S1抗原與HBV DNA結果間都具有很好的相關性。HBV DNA含量與前S1抗原及HBeAg陽性結果顯示：HBsAg陽性的肝硬化患者血清中HBV DNA陰性率為38.1%（含量＜103 copies/mL），而陽性檢出率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）。 結論 HBsAg陽性的肝硬化患者血清中主要以HBV非HBeAg陽性血清學模式為主，HBV DNA陽性檢出率的含量主要集中在103～105 copies/mL。前S1抗原在HBeAg陽性血清中與其含有HBsAg病毒及HBeAg陽性患者具有很好的相關性，而在HBeAg陰性血清中存在著差異。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.
目的通過分析乙型肝炎病毒（HBV）前S1抗原與乙型肝炎病毒e抗原（HBeAg）及肝功能指標谷丙轉氨酶之間的關系，探討HBV前S1抗原在病毒復制中的意義及與肝功能損害程度的相關性。 方法對2012年5月－7月住院及門診的HBV表面抗原陽性的慢性乙型肝炎患者血清標本310例進行檢測，HBV前S1抗原采用酶聯免疫吸附試驗檢測；HBeAg采用化學發光法檢測；谷丙轉氨酶采用酶學速率法檢測。 結果① HBeAg陽性組前S1抗原檢出率高；② HBV前S1抗原與具有病毒活動性復制意義的指標HBeAg有高度的相關性；③谷丙轉氨酶水平增高時前S1抗原陽性率增高。 結論HBV前S1抗原檢測結果可以較好地反映HBV的復制及慢性肝炎的活動情況。
