Abstract
Background Not all gastroesophageal reflux-induced cough (GERC) patients respond to anti-reflux treatment. It is not certain whether reflux-related symptoms or other clinical characteristics could indicate a successful response to anti-reflux treatment. In this study, we aimed to investigate the relationship between clinical features and anti-reflux response. Methods We retrospectively analyzed the clinical characteristics of suspected GERC who had reflux-related symptoms or reflux evidence based on abnormal 24-hour esophageal pH value monitoring, or who had no evidence of other common causes of chronic cough in our chronic cough database with a standard case report form. All patients experienced anti-reflux treatment with proton pump inhibitors (PPIs) plus prokinetic agents for at least 2 weeks and were divided into responders and non-responders based on the treatment response. Results Among 241 patients with suspected GERC, 146 (60.6%) showed a successful response. There was no significant difference in regard to the proportion of reflux-related symptoms, and results of 24-hour esophageal pH value monitoring between responders and non-responders. Compared with non-responders, responders had higher proportions of nasal itching (21.2% vs. 8.4%; P=0.014), tickle in the throat (51.4% vs. 35.8%; P=0.025) and lower proportion of pharyngeal foreign body sensation (32.9% vs. 54.7%; P=0.001). Multivariate analysis showed that nasal itching [hazard ratio (HR): 1.593, 95% confidence interval (CI): 1.025-2.476, P=0.039], tickle in the throat (HR: 1.605, 95% CI: 1.152-2.238, P=0.005), pharyngeal foreign body sensation (HR: 0.499, 95% CI: 0.346-0.720, P<0.001) and sensitivity to at least one cough trigger (HR: 0.480, 95% CI: 0.237-0.973, P=0.042) were associated with the therapeutic response. Conclusions Over half of suspected GERC patients benefited from anti-reflux therapy. A few clinical features rather than reflux-related symptoms might indicate a response to anti-reflux treatment. Further study is needed for the predictive value.

Abstract
OBJECTIVE We assessed whether the bicarbonate-rich mineral water Staatl. Fachingen STILL is superior over conventional mineral water in relieving heartburn. DESIGN Multicentre, double-blind, randomised, placebo-controlled trial STOMACH STILL in adult patients with frequent heartburn episodes since ≥6 months and without moderate/severe reflux oesophagitis. Patients drank 1.5 L/day verum or placebo over the course of the day for 6 weeks. Primary endpoint was the percentage of patients with reduction of ≥5 points in the Reflux Disease Questionnaire (RDQ) score for 'heartburn'. Secondary endpoints included symptom reduction (RDQ), health-related quality of life (HRQOL, Quality of Life in Reflux and Dyspepsia (QOLRAD)), intake of rescue medication and safety/tolerability. RESULTS Of 148 randomised patients (verum: n=73, placebo: n=75), 143 completed the trial. Responder rates were 84.72% in the verum and 63.51% in the placebo group (p=0.0035, number needed to treat=5). Symptoms improved under verum compared with placebo for the dimension 'heartburn' (p=0.0003) and the RDQ total score (p=0.0050). HRQOL improvements under verum compared with placebo were reported for 3 of 5 QOLRAD domains, that is, 'food/drink problems' (p=0.0125), 'emotional distress' (p=0.0147) and 'vitality' (p=0.0393). Mean intake of rescue medication decreased from 0.73 tablets/day at baseline to 0.47 tablets/day in week 6 in the verum group, whereas in the placebo group it remained constant during the trial. Only three patients had treatment-related adverse events (verum: n=1, placebo: n=2). CONCLUSION STOMACH STILL is the first controlled clinical trial demonstrating superiority of a mineral water over placebo in relieving heartburn, accompanied by an improved HRQOL. TRIAL REGISTRATION NUMBER EudraCT 2017-001100-30.

Abstract
The prevalence of the gastro-oesophageal reflux disease (GORD) in the western world is increasing. Uncontrolled GORD can lead to harmful long-term sequela such as oesophagitis, stricture formation, Barrett's oesophagus and oesophageal adenocarcinoma. Moreover, GORD has been shown to negatively impact quality of life. The current treatment paradigm for GORD consists of lifestyle modification, pharmacological control of gastric acid secretion or antireflux surgery. In recent years, several minimally invasive antireflux endoscopic therapies (ARET) have been developed which may play a role in bridging the unmet therapeutic gap between the medical and surgical treatment options. To ensure optimal patient outcomes following ARET, considered patient selection is crucial, which requires a mechanistic understanding of individual ARET options. Here, we will discuss the differences between ARETs along with an overview of the current evidence base. We also outline future research priorities that will help refine the future role of ARET.

Abstract
OBJECTIVE Number of reflux episodes, an adjunctive metric on pH-impedance monitoring, is incompletely studied. We aimed to determine if number of reflux episodes associates with therapeutic outcome in regurgitation predominant gastro-oesophageal reflux disease (GERD). DESIGN We performed post hoc analysis of postintervention pH-impedance data from adult patients with moderate/severe regurgitation despite QD proton pump inhibitor (PPI), randomised to either two times a day PPI or magnetic sphincter augmentation (MSA) in 2:1 allocation. After 6 and 12 months, symptom response was defined by improvement in Foregut Symptom Questionnaire (FSQ) regurgitation score to none or minimal, ≥50% reduction in GERD health-related quality of life (HRQL) score and satisfaction with therapy. Univariate and multivariate analyses were performed to determine predictors of symptom improvement. RESULTS Of 152 randomised patients, 123 (age 46.9±1.2 year, 43% female) had complete data. Symptom and satisfaction scores significantly improved after MSA compared with two times a day PPI. Both acid exposure time (13.4%±0.7% to 1.3±0.2%, p<0.001) and reflux episodes (86±4 to 48±4, p<0.001) declined with therapy. Reduction to <40 reflux episodes was significantly more frequent in those with symptom response by FSQ regurgitation score, GERD HRQL score and satisfaction with therapy (p≤0.03 for each); <35 episodes performed better on receiver operating characteristic analysis. On multivariate analysis, improvement in regurgitation score remained independently predictive of satisfaction with therapy (p<0.001 for each). In patients crossing over to MSA, >80 episodes pretreatment predicted improvement. CONCLUSIONS Reduction of reflux episodes on pH-impedance to physiological levels associates with improved outcomes, while pathological levels predict improvement with MSA in regurgitation predominant GERD.

Abstract
BACKGROUND: Recent trials involving pirfenidone suggest a beneficial effect in the treatment of idiopathic pulmonary fibrosis (IPF). OBJECTIVE: To report on the efficacy and safety of pirfenidone in the treatment of patients with IPF, at a tertiary care hospital in Saudi Arabia. METHODS: The study included 58 patients with IPF who were evaluated from March 2012 to March 2013. During the study period, 33 patients received pirfenidone, and the remaining patients (n = 25) served as a control group. Baseline clinical characteristics, physiological parameters and the results of a 36-Item Short Form Health Survey (SF-36) were compared between the groups. Furthermore, we compared changes in forced vital capacity (FVC), diffusion capacity of the lung for carbon monoxide (DLco), six-minute walk distance (6MWD) and SF-36 for both groups during follow-up. The last follow-up period ended in January 2014. RESULTS: There were no significant differences in baseline clinical characteristics between the groups. Furthermore, we found no differences in FVC, DLco and SF-36 during follow-up (median, 12 months). However, patients receiving pirfenidone treatment were less likely to experience reductions in 6MWD compared with the control group (13% vs. 52%, respectively; P = 0.001). Although adverse events were more frequently reported by the pirfenidone group compared with the control group (85 vs. 56%, respectively; P = 0.015), these patients did not require discontinuation of treatment. CONCLUSION: Pirfenidone treatment preserves functional capacity, as reflected by the 6MWD. Adverse events associated with pirfenidone treatment were generally well tolerated by the patients.

Abstract
OBJECTIVE Patients with non-erosive reflux disease (NERD) have impaired oesophageal mucosal integrity (dilated intercellular spaces). Oesophageal mucosal integrity reflects the balance between repeated reflux damage and mucosal recovery. The relationship between mucosal integrity and acid sensitivity is unclear. Oesophageal impedance may be used for in vivo mucosal integrity measurement. We studied acid-induced changes in oesophageal mucosal integrity and acid perception in patients with heartburn. DESIGN 50 patients with heartburn whithout oesophagitis underwent impedance monitoring before, during and after 10 min oesophageal perfusion with neutral (pH 6.5) and acid solutions (pH 1). Symptoms and impedance were recorded during perfusion. Impedance recovery was assessed for 2 h post-perfusion in ambulatory conditions followed by 24-h impedance-pH study. RESULTS Reflux monitoring discriminated 20 NERD and 30 functional heartburn (FH) patients. Neutral perfusion caused impedance fall that recovered within 10 min. Acid perfusion caused impedance fall with slow recovery: 6.5 Ω/min (IQR 3.3-12.0 Ω/min). Patients with slow recovery (< 25th percentile) had lower baseline impedance (1273 Ω ± 208 Ω vs. 3220 Ω ± 275 Ω ±, p < 0.01) and more frequent acid sensitivity (10/12 vs. 4/12, p = 0.04) than those with fast (> 75th percentile) recovery. Patients with NERD had lower baseline impedance (1669 ± 182 Ω vs. 2384 ± 211 Ω, p = 0.02) and slower impedance recovery (6.0 ± 0.9 Ω/min vs. 10.7 ± 1.6 Ω/min, p = 0.03) than patients with FH. CONCLUSION Impaired mucosal integrity might be the consequence of repeated reflux episodes with slow recovery. Mucosal integrity, recovery capacity and symptom perception are linked. Low basal impedance and slow recovery after acid challenge are associated with increased acid sensitivity.
