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.  相似文献

目的观察螺内酯与卡托普利治疗老年人慢性心力衰竭的疗效及安全性。方法 73例老年慢性心力衰竭患者随机分为卡托普利联合螺内酯组(A组)和卡托普利组(B组)。B组常规给予卡托普利、洋地黄制剂、速尿、倍他乐克治疗;A组在常规治疗基础上加用螺内酯20mg/d,连续用药6个月,对比治疗前后左心室舒张末期内径(LVEDD)、左心室收缩末期内径(LVESD)、左心室射血分数(LVEF)、短轴缩短率(FS)及血生化各项指标的变化。结果两组治疗后超声心动图各项指标均得到改善,但A组LVEDD的缩小更明显[(59.4±7.9)mm比(46.7±3.5)mm,P0.01]。两组治疗前后血生化各项指标均无显著变化,不良反应发生率相仿(P〉0.05)。结论小剂量螺内酯联合卡托普利能改善老年慢性心力衰竭的左心室重构,且安全性良好。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

目的 了解慢性乙型肝炎(慢性乙肝)患者血清趋化因子RANTES水平,探讨血清RANTES水平与丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、总胆红素(TBil)、凝血酶原活动度(PTA)、乙型肝炎e抗原(HBeAg)及乙型肝炎病毒(HBV DNA)载量的相关性.方法 选择144例慢性乙肝患者(观察组)和18名健康人(对照组),采取静脉血并应用ABC-ELISA方法 检测其血清中趋化因子RANTES浓度,并与两组的肝功能检测生化指标、HBeAg和HBV DNA载量进行相关性分析,利用SPSS13.0软件进行统计分析.结果 慢性乙肝患者血清RANTES的浓度比正常对照组升高,血清RANTES浓度分别为(3930.12±2856.96)ng/ml和(329.46±152.23)ng/ml,两组之间差异比较均有统计学意义(P<0.05);RANTES水平与ALT(r=0.197,P:0.018)、AST(r=0.239,P=0.004)和Tnil(r=0.316,P=0.001)呈显著正相关;RANTES水平与PTA(r=-0.078,P=0.357)无显著相关;HBeAg阴性组与HBeAg阳性RANTES水平比较无统计学意义(P=0.407);HBV DNA低载量组(<105拷贝/ml)和HBVDNA高载量组(≥105拷贝/ml)RANTES水平比较无统计学意义(P=0.185).结论 慢性乙肝患者血清中RANTES表达水平增高,血清RANTES水平与ALT、AST和TBIL呈正相关,与PTA无相关性.RANTES水平可反映肝脏炎症活动及损害情况,不受HBeAg、HBV DNA载量影响,可能参与慢性乙肝发病.  相似文献
