慢性乙肝患者血清趋化因子RANTES水平与肝功能生化指标等的相关性研究

Objective To investigate the level of the serum chemokine RANTES and its correlation with serum biochemical indices of liver function test, HBeAg and HBV DNA load in patients with chronic hepatitis B.Methods 144 patients with chronic hepatitis B (observed group) and 18 normal cases (control group) were enrolled in this study. The serum level of chemokine RANTES was detected with an ABC-ELISA assay. Statistical analysis was performed on the software of SPSS13.0. Results The serum chemokine RANTES level in the observed group (3930.12 ng/ml±2856.96) ng/ml was significantly higher than that in the control group (329.46 ng/ml±152.23) ng/ml. The results from the observed group indicated the positive correlation of serum RANTES level with indices of liver function test, including ALT (r=0. 197, P=0.018), AST(r=0.239, P=0.004) and TBil (r=0.316, P=0.001), but did not with PTA (r=-0.078, P=0.357). Neither difference of serum chemokine RANTES level between HBeAg-positive group and HBeAg-negative group nor that between high HBV DNA load group (≥105 copies/ml) and low HBV DNA load group (< 105 copies/ml) were statistically significant (P=0.407 and 0.185, respectively). Conclusions Serum chemokine RANTES level in patients with chronic hepatitis B elevates significantly and is not affected by HBeAg or HBV DNA load. Its positive correlation with indices of liver function test indicates that RANTES might play an important rule in the pathogenesis of chronic hepatitis B.     

HBeAg阴性与阳性慢性乙肝患者的临床对比分析

目的 探讨HBeAg阳性和HBeAg阴性慢性乙肝患者的临床特征异同.方法 随机选取慢性乙肝患者354例,其中HBeAg阳性组124例,HBeAg阴性组230例,对两组的人口学、生化学、病毒学及诊断分型进行分析比较.结果 ①与HBeAg阳性组比较,HBeAg阴性组患者年龄较大(P=0.000),中度和重度慢性肝炎比例较低(P:0.007和0.014),重型肝炎发生率较高(P=0.008).②HBeAg阴性组的ALT、ALB、PTA及HBV DNA载量对数值低于HBeAg阳性组(P=0.035,0.002,0.000和0.000),但TBil水平高于HBeAg阳性组(P=0.003);两组AST水平差异无统计学意义(P=0.222).③HSeAs阴性组在高病毒载量组(HBV DNA105拷贝/m1)的比例低于HBeAg阳性组(37.4%VS55.6%,P=0.001).结论 HBeAg阴性患者与HBeAg阳性患者相比存在年龄偏大和HBV DNA水平较低等特征,HBeAg阴性乙肝患者的病情有时反而可能较重.
