简介:胃内幽门螺杆菌(简称Hp)感染与消化疾病密切相关[1],故诊断Hp感染显得尤为重要.目前诊断Hp的方法很,多为侵人性(包括快速尿素酶、病理染色、细菌培养等),对患者具有一定创伤和痛苦;血清Hp-IgG抗体测定为非侵人性,但根除Hp后血清Hp抗体需长时间才能转阴,不宜疗效考核.无创伤性呼气试验可作为根除Hp前后诊断的金标准[2].我院于1998年5月至1999年5月,采用微量14C-尿素呼气法(简称14C-UBT)诊断Hp感染,同时予快速尿素酶法(RUT)、病理染色(W-S染色)对照,及追踪根除Hp后疗效检测.旨在观察14C-UBT法在诊断胃内Hp感染的临床价值.

简介:目的:评估幽门螺杆菌(Hpylori)粪便抗原(HpSA)试验诊断H.pylori感染的准确性.方法:应用酶免疫反应原理进行HpSA试验,在大样本、多中心研究中进行HpSA试验的评估.995例因消化不良症状接受胃镜检查者纳入本研究,所有患者均以HpSA试验、快速尿素酶试验(RUT)和组织学(或培养)方法检测H.pylori.以RUT和组织学(或培养)联合检测作为"金标准",两项试验均阳性者定为H.pylori感染.结果:以光密度值≥0.16为阳性,HpSA检测诊断H.pylori感染的敏感性为93.5%(478/511),特异性为94.2%(456/484),阳性预测值为94.5%(478/506),阴性预测值为93.3%(456/489),总的检测准确性为93.9%(934/995).结论:HpSA试验是一种简便、准确的非侵入性H.pylori感染检测方法.
简介:目的评价熊去氧胆酸(UDCA)治疗原发性胆汁性肝硬化(PBC)患者的疗效和安全性。方法本研究采用随机平行对照试验设计方案,将90例PBC患者随机分为试验组和对照组,每组45例。两组受试者均给予保肝支持疗法,试验组受试者在此基础上给予UDCA250mg口服,3次/d;给予对照组受试者泼尼松治疗。两组均治疗4w。常规检测血清总胆红素(TBIL),丙氨酸氨基转移酶(ALT),天冬氨酸氨基转移酶(AST),碱性磷酸酶(ALP),总胆汁酸(TBA)和γ-谷氨酰转肽酶(GGT)。记录治疗期间受试者的不良反应发生情况。结果在治疗4w末,试验组受试者血清T-BIL、ALT、AST、ALP和GGT水平分别为(34.19±16.88)μmol/L、(48.58±23.31)U/L、(37.27±18.33)U/L、(104.51±43.55)U/L和(82.68±33.34)U/L,均显著低于对照组的(67.35±31.10)μmol/L、(85.27±31.88)U/L、(73.55±15.71)U/L、(197.09±52.36)U/L和(131.66±37.58)U/L(P〈0.01);试验组受试者血清TBA为(20.27±9.11)μmol/L,显著高于对照组的(3.27±1.89)μmol/L(P〈0.01);两组不良反应发生率比较,如便秘(P=0.29)、头痛(P=0.29)、头晕(P=0.50)、心动过速(P=0.50)、恶心(P=0.33)和呕吐(P=0.50)等,均无显著性相差。结论UDCA治疗PBC患者的疗效优于泼尼松,且该药的不良反应较少,受试者可以耐受。
