| 1 | Proton pump inhibitor resistance, the real challenge in gastro-esophageal reflux disease显示文摘Gastro-esophageal reflux disease(GERD)is one of the most prevalent chronic diseases.Although proton pump inhibitors(PPIs)represent the mainstay of treatment both for healing erosive esophagitis and for symptom relief,several studies have shown that up to 40%of GERD patients reported either partial or complete lack of response of their symptoms to a standard PPI dose once daily.Several mechanisms have been proposed as involved in PPIs resistance,including ineffective control of gastric acid secretion,esophageal hypersensitivity,ultrastructural and functional changes in the esophageal epithelium.The diagnostic evaluation of a refractory GERD patients should include an accurate clinical evaluation,upper endoscopy,esophageal manometry and ambulatory pH-impedance monitoring,which allows to discriminate non-erosive reflux disease patients from those presenting esophageal hypersensitivity or functional heartburn.Treatment has been primarily based on doubling the PPI dose or switching to another PPI.Patients with proven disease,not responding to PPI twice daily,are eligible for anti-reflux surgery. | Michele Cicala Sara Emerenziani Michele Pier Luca Guarino Mentore Ribolsi | 2013 | World Journal of Gastroenterology2013，19，39： | 38 |
| 2 | 质子泵抑制剂联合伊托必利治疗胃食管反流病18个月疗效观察显示文摘目的观察质子泵抑制剂+伊托必利联合维持治疗对胃食管反流病(GERD)患者的远期疗效。方法经内镜、24h食管pH测定或PPI试验确诊的GERD患者140例,其中非糜烂性反流病(NERD)58例、糜烂性食管炎(EE)64例、Barrett食管(BE)18例,采用前瞻性、随机对照随访研究,分别按维持治疗方案分为3个亚组,于治疗前、初始治疗结束时(8周)、治疗12个月、治疗18个月后进行GerdQ评分及内镜检查。结果经8周初始治疗,NERD、EE及BE患者GerdQ评分均较治疗前降低(P=0.000);治疗12个月后,NERD、EE及BE患者平均GerdQ评分均较8周时下降(P=0.000);治疗18个月后,三组的GerdQ评分进一步下降,其中EE及BE患者的GerdQ评分与12个月时比较差异均有显著性(P=0.039及P=0.032)。治疗12个月后,EE患者中减量维持亚组的GerdQ评分低于按需治疗组(P=0.008);治疗18个月后,NERD组及EE组中减量维持亚组的GerdQ评分均低于按需治疗组(P=0.042及P=0.037)。维持治疗12个月及18个月后与治疗前比较,EE患者食管黏膜内镜下5种表现的构成比有极显著性差异(P=0.000)。结论 GERD的症状改善及黏膜愈合程度随维持治疗时间的延长而更趋于明显并持续;就疗效而言,减量维持治疗优于按需治疗方案;18个月随访,PPI及ITO应用具有良好的安全性和耐受性。 | 牛春燕 汪雯 李雷 高保华 单婕 张婷 罗金燕 | 2013 | 胃肠病学和肝病学杂志2013，22，8： | 13 |
| 3 | 非糜烂性胃食管反流病的中西医治疗进展显示文摘非糜烂性胃食管反流病(non-erosive relux disease。NERD)一般是指由食管酸反流引起食管反流的典型症状〉3个月.而内镜下没有可见的黏膜损伤的反流病.亦称内镜阴性反流病。是临床上最常见的胃食管反流病(gastroesophageal reflux disease,GERD),约占GERD的50%-70%。近年来,NERD的发病有逐年上升的趋势.已成为严重影响人们生活质量的主要消化系统疾病.其对生理功能、社会功能的影响超过了其他慢性病如糖尿病、高血压等。 | 丰金香 陈朝明 | 2014 | 实用医学杂志2014，30，19： | 13 |
| 4 | Proton pump inhibitor for non-erosive reflux disease:A meta-analysis显示文摘AIM:To evaluate the efficacy,safety and influential factors of proton pump inhibitor(PPI)treatment for non-erosive reflux disease(NERD).METHODS:PubMed,MEDLINE,EMBASE and the Cochrane Library were searched up to April 2013 to identify eligible randomized controlled trials(RCTs)that probed into the efficacy,safety and influential factors of PPI treatment for NERD.The rates of symptomatic relief and adverse events were measured as the outcomes.After RCT selection,assessment and data collection,the pooled RRs and 95%CI were calculated.This meta-analysis was performed using the Stata 12.0 software(Stata Corporation,College Station,Texas,United States).The level of evidence was estimated by the Grading of Recommendations Assessment,Development and Evaluation system.RESULTS:Seventeen RCTs including 6072 patients met the inclusion criteria.The results of the metaanalysis showed that PPI treatment was significantly superior to H2receptor antagonists(H2RA)treatment(RR=1.629,95%CI:1.422-1.867,P=0.000)and placebo(RR=1.903,95%CI:1.573-2.302,P=0.000)for the symptomatic relief of NERD.However,there were no obvious differences between PPI and H2RA(RR=0.928,95%CI:0.776-1.110,P=0.414)or PPI and the placebo(RR=1.000,95%CI:0.896-1.116,P=0.997)regarding the rate of adverse events.The overall rate of symptomatic relief of PPI against NERD was 51.4%(95%CI:0.433-0.595,P=0.000),and relief was influenced by hiatal hernia(P=0.030).The adverse rate of PPI against NERD was 21.0%(95%CI:0.152-0.208,P=0.000),and was affected by hiatal hernia(P=0.081)and drinking(P=0.053).CONCLUSION:PPI overmatched H2RA on symptomatic relief rate but not on adverse rate for NERD.Its relief rate and adverse rate were influenced by hiatal hernia and drinking. | Ji-Xiang Zhang Meng-Yao Ji Jia Song Hong-Bo Lei Shi Qiu Jing Wang Ming-Hua Ai Jun Wang Xiao-Guang Lv Zi-Rong Yang Wei-Guo Dong | 2013 | World Journal of Gastroenterology2013，19，45： | 8 |
