ABSTRACT

Objectlve To review the clinical characteristics,esophageal motility and acid exposure in elderly patients with gastroesophageal reflux disease (GERD).Methods Two hundred and sixty patients aged 18 -81 years were diagnosed as gastroesophageal reflux disease from 2005 to 2011 in outpatient clinic,the patients were divided into elderly group ( ≥ 60 y) and control group ( < 60 y).The incidence of esophagitis,severity of esophagitis,esophageal motility and esophageal acid exposure were analyzed and compared between two groups.Results The incidence of esophageal hiatal hernia,non-typical reflux symptoms and extra-esophageal symptoms in elderly group were higher than that of control group(45.1% vs.30.6%,36.3% vs.27.2% and 37.1% vs.25.2%,P =0.016,0.005 and 0.037,respectively).There was no significant difference in esophagitis incidence between two group (55.8% vs.50.3%,P =0.250).The incidence of esophagitis graded as LA-B to LA-D were higher in elderly group( 19.5% vs.10.2% and 8.8% vs.2.7%,P =0.034 and 0.030,respectively).The percentage of upright acid clearance time,supine reflux time of pH <4 and the DeMeester score of elderly group were higher than those of control group (P =0.000,0.006 and 0.001,respectively).Lower esophageal sphincter pressure (LESP) of elderly group was lower than that of control group ( 13.36 ±6.39 vs.15.57 ±7.01,P =0.009).Conclusion In comparison with young and middle-aged patients,the elderly GERD patients have lower esophageal motility,longer esophageal acid exposure time and higher frequency of severer esophagitis.

ABSTRACT

ObjectiveTo investigate the characteristics of gastroesophageal reflux disease (GERD) with chronic cough by the results of combined multichannel intraluminal impedance and high-resolution manometry (MII-HRM) procedure and 24-hour muhichannel intraluminal impedance combined pH (MII pH) monitoring.Methods From March 2010 to November 2010,consecutive patients of GERD with chronic cough (more than 8 weeks) admitted to Beijing Chaoyang Hospital of Capital Medical University underwent 24-hour MII-pH monitoring and MII-HRM procedure with symptom association probability(SAP) over 95%.Data of lower esophageal sphincter (LES) pressure,LES relaxation,LES residual pressure,esophageal body peristalsis function and swallow bolus transit (liquid/viscous) was collected and the result of 24-hour MII-pH monitoring was analysed by the computer software containing reflux episode activity(acid/nonacid,upright/recumbent),proximal extent,acid exposure and mean acid/bolus clearance time.Seventeen patients of GERD with typical reflux symptom were selected as the control group.ResultsComparing with patients of GERD with typical reflux symptom,patients of GERD with chronic cough showeddecreased upper esophageal sphincter pressure (UESP) [( 122.55 ± 60.48 )mm Hg vs ( 86.37 ± 41.35 ) mm Hg,P < 0.05,1 mm Hg =0.133 kPa ],higher percentage of abnormality peristalsis [(9.47 ± 15.63 ) % vs ( 22.16 ± 17.45 ) %,P < 0.05 ],degraded esophagus transmittability of liquid substance [( 88.82 ± 12.23) % vs ( 71.68 ± 23.06 ) %,P < 0.05 ],more reflux episode activity ( acid/nonacid ) in supine position and proximal reflux episode (nonacid) in supine position (P < 0.05 )and longer mean bolus clearance time( P < 0.05 ).Conclusion Decrease of the UESP,increase of the reflux episode activity (acid/nonacid) in supine position and proximal reflux episode (nonacid) in supine position,lengthened mean bolus clearance time in supine position and the degraded esophagus clearance ability may all correlated with the pathogenesy of GERD with chronic cough.

ABSTRACT

Objective To determine the prevalence of gastroesophageal reflux disease (GERD) in patients with idiopathic pulmonary interstitial fibrosis (IPIF). Methods From December 2006 to January 2008, 24 consecutive patients with IPIF admitted to Beijing Chaoyang Hospital underwent 24-hour esophageal pH monitoring and esophageal manometry. Meanwhile, 23 patients with diffuse parenchymal lung disease (DPLD) (excluding IPIF) admired to the hospital in the same period served as a control group. Comparison of the prevalence of pathologic esophageal acid exposure GERD symptoms, and ineffective esophageal motility (IEM) between the two groups was made. In this study, nocturnal acid exposure is defined as acid reflux episodes occurring from 10pro to 6am. Results (1) 16 out of the 24 (66. 7%) patients with IPIF were demonstrated to have pathologic esophageal acid exposure; the prevalence of GERD in IPIF patients was significantly higher than that in other DPLD patients, whose prevalence was 26. 1% (P<0.05); (2) 87.5% patients with IPIF and GERD (GERD-IPIF) had nocturnal acid exposure episodes; (3) only 37.5% of the GERD-IPIF patients was found to have typical GERD symptoms such as heartburn and regurgitation; (4) The prevalence of IEM was similar in IPIF and other DPLD patients, being 42.9% and 39. 1% respectively (P >0. 05). Conclusions IPIF patients have higher prevalence of GERD and most of them usually do not show typical reflux symptoms. It is hereby suggested that IPIF patients should be screened with pH monitoring for GERD.
