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.

特殊人群慢性乙型肝炎的抗病毒治疗

在慢性乙型肝炎患者中,儿童、育龄/妊娠妇女、肝硬化、肝脏移植受者、接受免疫抑制剂/化疗、原发性肝癌、HBV与HCV或HDV或HIV共感染等特殊人群的抗病毒治疗问题需要探索,并日益受到重视。关于此类患者的抗病毒指征、药物选择、治疗方案和抗病毒疗程是研究的主要热点和难点。我国、亚太(APASL)和欧洲肝病学会(EASL)等指南亦对此类患者的抗病毒治疗做了相关的推荐。干扰素仍然适用于一部分特定慢性乙型肝炎人群,如儿童、代偿期肝硬化和HBV与HCV或HDV共感染等,但核苷(酸)类似物更被广泛推荐使用。

目的 探讨HBeAg阴性的乙型肝炎肝硬化患者接受核苷（酸）类似物治疗过程的护理要点.方法 将111例患者分为抗病毒组58例和对照组53例,抗病毒组在常规护肝治疗的基础上加用核苷（酸）类似物抗病毒治疗,对照组给予常规护肝治疗,对所有患者进行护理观察,总结护理要点.结果 除死亡8例外其余患者均完成96周治疗和随访,抗病毒组的ALT复常率和HBV DNA下降幅度均高于对照组,抗病毒组及对照组的HBV DNA转阴率（〈500拷/m1）分别为88.7%及32.5%,两组差异有统计学意义（x2=31.427,P=0.001）.结论 核苷（酸）类似物对HBeag阴性的肝硬化能有效抑制HBV复制,改善肝硬化患者肝功能.在治疗过程中做好疾病及药物知识宣教,建立良好的护患关系,强化患者的遵医行为,及时观察处理并发症,是治疗成功的关键.     

FIB-4指数对慢性乙型肝炎患者肝纤维化的诊断价值

目的 探讨FIB-4指数对慢性乙型肝炎肝纤维化的诊断价值.方法 212例慢性乙型肝炎患者行肝活检并同时留取血清标本,检测ALT、AST、PLT等指标,并根据其结果结合患者的年龄计算出FIB-4的数值.根据肝纤维化分期设定3个判定点,分别为显著纤维化（S2～S4期）,严重纤维化（S3～S4期）和肝硬化（S4期）.以肝活检病理结果为金标准绘制出FIB-4的受试者工作特征曲线（ROC）,计算曲线下面积（AUC）,评价其对慢性乙型肝炎肝纤维化的诊断价值.结果 212例肝活检患者中S0期3例（1.4%）,S1期49例（23.1%）,S2期66例（31.1%）,S3期50例（23.6%）,S4期44例（20.8%）,即显著纤维化者（S2～S4期）160例（75.5%）,严重纤维化者（S3～S4期）94例（44.3%）,肝硬化者（S4期）44例（20.8%）.FIB-4指数对3个判定点的AUC值分别为0.733（95%（CI：0.660～0.806,P〈0.01）、0.746（95%CI：0.679～0.813,P〈0.01）、0.756（95%CI：0.687～0.825,P〈0.01）.结论 FIB-4指数是一种简单的、准确的、经济的非创性诊断方法,可以较准确地估计慢性乙型肝炎患者有无显著纤维化,使多数患者避免肝穿刺活检.     

慢性乙型肝炎患者病理与临床诊断的差异性分析

目的 探讨慢性乙型肝炎的临床诊断与病理诊断的差异性,寻求更客观的临床诊断标准.方法 选择319例慢性乙型肝炎患者进行肝组织穿刺检查及肝组织病理学检查,对临床诊断与病理诊断结果的差异性进行分析.统计学分析采用非参数检验.结果 以病理诊断结果为参考,临床诊断轻度、中度、重度及肝硬化的准确率分别为67.3%、37.6%、2.7%和23.5%,其中肝硬化临床诊断漏诊率达93.4%;临床诊断轻度、中度和重度患者与病理诊断纤维化分期符合率较高,分别为75.0%、81.7%和83.8%,肝硬化的临床诊断与病理纤维化分期符合率较低,为23.5%;在临床诊断或病理诊断中,轻度、中度、重度以及肝硬化组间的ALT、TBil水平并非逐渐增高.结论 慢性乙型肝炎的临床诊断与病理诊断存在较大差异;重度肝炎及肝硬化患者临床诊断的准确率较低,对这些患者最好结合肝穿刺组织学检查结果综合考虑,以提高诊断的准确率.     

巨噬细胞移动抑制因子与慢性乙型肝炎、乙型肝炎肝硬化的关系

目的 了解慢性乙型肝炎(乙肝)及乙肝肝硬化患者血清细胞因子巨噬细胞移动抑制因子(MIF)表达水平,探讨血清MIF水平与Ⅲ型前胶原肽(PⅢP)、组织金属蛋白酶抑制剂-1(TIMP-1)的相关性.方法 选择44例慢性乙肝患者(肝炎组)、44例乙肝肝硬化患者(肝硬化组)和30名健康者(对照组),取静脉血并应用ELISA方法检测其血清中细胞因子MIF浓度,分析实验组血清MIF水平与PⅢP、TIMP-1相关性.两组间均数比较采用t检验,MIF水平与ALT、AST、TBil、PTA、PⅢP及TIMP-1关系采用直线相关分析.结果 慢性乙肝组及肝硬化组血清MIF、PⅢP及TIMP-1的浓度比健康对照组升高.差异均有统计学意义(t=12.87、5.28、10.98,t=11.22、14.84、11.17)均P<0.05),但该3种细胞因子在慢性乙肝及肝硬化患者之间差异无统计学意义(t=-1.05、1.52、-2.07;均P>0.05);MIF水平与ALT、AST、TBil及PTA均无相关性;HBeAg阳性和高病毒载量(>1×105拷贝/mL)慢性乙肝患者体内MIF水平高于HBeAg阴性和低病毒载量(≤1×105拷贝/mL)患者.MIF水平与PⅢP水平在慢性乙肝组和肝硬化组中均存在正相关(r=0.603,P<0.05;r=0.415,P<0.05);MIF水平与TIMP-1水平在慢性乙肝组中存在正相关(r=0.458,P<0.05),而在肝硬化组无相关性(r=0.210,P>0.05),PⅢ P与TIMP-1在慢性乙肝组及肝硬化组均存在相关性(r=0.649,P<0.05)r=0.424,P<0.05).结论 慢性乙肝及肝硬化患者体内MIF水平明显升高,MIF的早期生成可能与病毒复制有关,与肝功能无关;MIF参与了肝炎,肝纤维化及肝硬化形成过程,可反应肝硬化程度.
