HBV抗原定量对干扰素联合阿德福韦酯治疗HBeAg阳性慢乙肝的疗效预测

Objective To investigate the levels of HBsAg in predicting the efficacy of peglated interferon-alpha 2a combined with adefovir dipivoxil( ADV ), in HBeAg-positive chronic hepatitis B patients.Methods This trial enrolled 62 HBeAg-positive chronic hepatitis B patients with detectable HBsAg for at least 6 months prior to screening, serum HBV DNA levels of at least 100 000 IU/ml. The efficacy assessment: viral suppression below 100 IU/ml. The patients with HBV DNA ≤ 100 IU/ml after 24 weeks therapy were divided into group A, in which monotherapy continued; While the rest were divided into group B, in which ADV was combined until week 48. In group B, at the end-of-treatment, the patients with HBV DNA ≤100 IU/ml were divided into group B1, the rest were divided into group B2. Results There was no significant difference on the beseline characteristics of patients between B1 and B2. There was significant difference on the levels of HBsAg at 12-week and 24-week between B1 and B2; while there was no significant difference on the levels of HBeAg. Conclusions The levels of HBsAg at 12-week and 24-week would be predictors to evaluate the efficacy of combined therapy in HBeAg-positive chronic hepatitis B patients.     

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.     

慢性乙型肝炎患者肝功能及血清HBeAg和HBV DNA载量与肝组织病理相关性的研究

目的 探讨慢性乙型肝炎患者肝功能、HBeAg及HBV DNA水平与肝组织病理炎症分级和纤维化分期的关系.方法 选择233例慢性乙型肝炎患者进行肝穿病理学检查,同时所有患者检测HBV DNA、HBeAg及肝功能,比较患者的肝功能、HBeAg及HBV DNA水平在不同病理炎症分级及纤维化分期中的差异情况.结果 不同的炎症分级患者中,ALT以C3组最高,G0～1组最低,各组间比较差异有统计学意义(P =0.016);TBil以G4组最高,G0～1组最低,各组间比较差异有统计学意义(P=0.000);HBV DNA载量各组间差异无统计学意义.不同的纤维化分期患者中,ALT各组间比较差异无统计学意义;TBil以S4组最高,S2组最低,各组间比较差异有统计学意义(P=0.039);HBV DNA载量各组间差异无统计学意义.炎症分级为G3～4的患者比例在HBeAg阳性组与阴性组差异无统计学意义.纤维化分期S3～4的患者比例在HBeAS阳性组(38%)比HBeAg阴性组(53%)低,两组差异有统计学意义(P=0.025).结论 慢性乙型肝炎患者血清HBV DNA水平的高低不能反映其肝脏炎症及纤维化程度,HBeAg阴性慢乙肝患者肝组织纤维化程度较高,TBil水平与肝组织炎症分级及纤维化分期均有良好的相关性,ALT水平与炎症分级有一定的关联性,但与纤维化分期无关.
