Project description:BACKGROUND/AIMS:To compare gastroesophageal reflux disease (GERD) symptoms and response to proton pump inhibitor (PPI) in patients with erosive esophagitis (EE), non-erosive reflux disease (NERD) or functional heartburn (FH) using GERD impact scale (GIS) questionnaire. METHODS:Total 126 patients with GERD symptoms were diagnosed as EE (n = 62), NERD (n = 34) and FH (n = 30) by endoscopy, 24-hour esophageal pH testing and Bernstein test, prospectively. Analysis of risk factors and GIS questionnaire for GERD symptoms and quality of life were performed before and 8 weeks after PPI treatment. RESULTS:EE group had a higher proportion of men, frequent alcohol consumption, smoking, hiatal hernia, body mass index ? 25 kg/m(2) and triglyceride levels (? 150 mg/dL) than the other groups (all P < 0.05). On the other hand, both psychiatric treatment and psychopharmacotherapy were more frequent in patients with FH than in those with EE and NERD (both P < 0.05). Among GERD symptoms, chest pain was more frequent in FH group than in EE and NERD groups (P < 0.05). Eating problems and limitation of productive daily activities occurred frequently in FH group and NERD group, respectively. GIS after 8 week PPI treatment showed improvement in all of the GERD symptoms in EE (all P < 0.05) and in acid regurgitation, epigastric pain and hoarseness in NERD group (all P < 0.05). In terms of quality of life, PPI treatment improved sleep disturbance in EE (P = 0.031) and limitation of productive activity in the NERD group (P = 0.001). CONCLUSIONS:GIS questionnaire showed that different characteristics and symptoms improved after PPI therapy among patients with EE, NERD and FH, demonstrating the usefulness of the GIS questionnaire.

Project description:Background & aimsThere are few data on the prevalence of gastroesophageal reflux disease (GERD) in the United States. We performed a population-based study to determine the prevalence of GERD symptoms and persistent GERD symptoms despite use of proton pump inhibitors (PPIs).MethodsWe conducted the National Gastrointestinal Survey in 2015 using MyGiHealth, an app that guides participants through National Institutes of Health gastrointestinal Patient-Reported Outcomes Measurement Information System surveys. Primary outcomes were prevalence of GERD symptoms in the past and persistence of GERD symptoms (heartburn or regurgitation 2 or more days in past week) among participants taking PPIs. Population weights were applied to the data and multivariable regression was used to adjust for confounding.ResultsAmong 71,812 participants, 32,878 (44.1%) reported having had GERD symptoms in the past and 23,039 (30.9%) reported having GERD symptoms in the past week. We also found that 35.1% of those who had experienced GERD symptoms were currently on therapy (55.2% on PPIs, 24.3% on histamine-2 receptor blockers, and 24.4% on antacids). Among 3229 participants taking daily PPIs, 54.1% had persistent GERD symptoms. Younger individuals, women, Latino individuals, and participants with irritable bowel syndrome or Crohn's disease were more likely to have continued symptoms, even when taking PPIs.ConclusionsUsing a population-based survey, we found GERD symptoms to be common: 2 of 5 participants have had GERD symptoms in the past and 1 of 3 had symptoms in the past week. We also found that half of PPI users have persistent symptoms. Given the significant effect of GERD on quality of life, further research and development of new therapies are needed for patients with PPI-refractory GERD symptoms.

Project description:Up to 40% of patients with gastroesophageal reflux disease (GERD) report persistent symptoms despite proton pump inhibitor (PPI) therapy. This review outlines the evidence for surgical and endoscopic therapies for the treatment of PPI nonresponsive GERD. A literature search for GERD therapies from 2005 to 2015 in PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews identified 2928 unique citations. Of those, 45 unique articles specific to surgical and endoscopic therapies for PPI nonresponsive GERD were reviewed. Laparoscopic fundoplication (n = 19) provides symptomatic and physiologic relief out to 10 years, though efficacy wanes with time. Magnetic sphincter augmentation (n = 6) and transoral incisionless fundoplication (n = 9) improve symptoms in PPI nonresponders and may offer fewer side effects than fundoplication, though long-term follow-up is lacking. Radiofrequency energy delivery (n = 8) has insufficient evidence for routine use in treating PPI nonresponsive GERD. Electrical stimulator implantation (n = 1) and endoscopic mucosal surgery (n = 2) are newer therapies under evaluation for the treatment of GERD. Laparoscopic fundoplication remains the most proven therapeutic approach. Newer antireflux procedures such as magnetic sphincter augmentation and transoral incisionless fundoplication offer alternatives with varying degrees of success, durability, and side effect profiles that may better suit individual patients. Larger head-to-head comparison trials are needed to better characterize the difference in symptom response and side effect profiles.

Project description:HypothesisScreening for esophageal adenocarcinoma has focused on identifying Barrett esophagus (BE) in patients with severe, long-standing symptoms of gastroesophageal reflux disease (GERD). Unfortunately, 95% of patients who develop esophageal adenocarcinoma are unaware of the presence of BE before their cancer diagnosis, which means they never had been selected for screening. One possible explanation is that no correlation exists between the severity of GERD symptoms and cancer risk. We hypothesize that severe GERD symptoms are not associated with an increase in the prevalence of BE, dysplasia, or cancer in patients undergoing primary endoscopic screening.DesignCross-sectional study.SettingUniversity hospital.PatientsA total of 769 patients with GERD.InterventionsPrimary screening endoscopy performed from November 1, 2004, through June 7, 2007.Main outcomes measuresSymptom severity, proton pump inhibitor therapy, and esophageal adenocarcinogenesis (ie, BE, dysplasia, or cancer).ResultsEndoscopy revealed adenocarcinogenesis in 122 patients. An increasing number of severe GERD symptoms correlated positively with endoscopic findings of esophagitis (odds ratio, 1.05; 95% confidence interval, 1.01-1.09). Conversely, an increasing number of severe GERD symptoms were associated with decreased odds of adenocarcinogenesis (odds ratio, 0.94; 95% confidence interval, 0.89-0.98). Patients taking proton pump inhibitors were 61.3% and 81.5% more likely to have adenocarcinogenesis if they reported no severe typical or atypical GERD symptoms, respectively, compared with patients taking proton pump inhibitors, who reported that all symptoms were severe.ConclusionsMedically treated patients with mild or absent GERD symptoms have significantly higher odds of adenocarcinogenesis compared with medically treated patients with severe GERD symptoms. This finding may explain the failure of the current screening paradigm in which the threshold for primary endoscopic examination is based on symptom severity.

Project description:Background and aimsProton pump inhibitor (PPI) therapy fails to provide adequate symptom control in up to 50% of patients with gastroesophageal reflux symptoms. Although a proportion do not require ongoing PPI therapy, a diagnostic approach to identify candidates appropriate for PPI cessation is not available. This study aimed to examine the clinical utility of prolonged wireless reflux monitoring to predict the ability to discontinue PPIs.MethodsThis double-blinded clinical trial performed over 3 years at 2 centers enrolled adults with troublesome esophageal symptoms of heartburn, regurgitation, and/or chest pain and inadequate PPI response. Participants underwent prolonged wireless reflux monitoring (off PPIs for ≥7 days) and a 3-week PPI cessation intervention. Primary outcome was tolerance of PPI cessation (discontinued or resumed PPIs). Symptom burden was quantified using the Reflux Symptom Questionnaire electronic Diary (RESQ-eD).ResultsOf 128 enrolled, 100 participants met inclusion criteria (mean age, 48.6 years; 41 men). Thirty-four participants (34%) discontinued PPIs. The strongest predictor of PPI discontinuation was number of days with acid exposure time (AET) > 4.0% (odds ratio, 1.82; P < .001). Participants with 0 days of AET > 4.0% had a 10 times increased odds of discontinuing PPI than participants with 4 days of AET > 4.0%. Reduction in symptom burden was greater among the discontinued versus resumed PPI group (RESQ-eD, -43.7% vs -5.3%; P = .04).ConclusionsAmong patients with typical reflux symptoms, inadequate PPI response, and absence of severe esophagitis, acid exposure on reflux monitoring predicted the ability to discontinue PPIs without symptom escalation. Upfront reflux monitoring off acid suppression can limit unnecessary PPI use and guide personalized management. (ClinicalTrials.gov, Number: NCT03202537).

Project description:Up to 40% of patients report persistent gastroesophageal reflux disease (GERD) symptoms despite proton pump inhibitor (PPI) therapy. This review outlines the evidence for medical therapy for PPI nonresponsive GERD. A literature search for GERD therapies from 2005 to 2015 in PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews identified 2928 unique citations. Of those, 40 unique articles specific to the impact of PPI metabolizer genotype on PPI response and the use adjunctive medical therapies were identified. Thirteen articles reported impacts on CYP genotypes on PPI metabolism demonstrating lower endoscopic healing rates in extensive metabolizers; however, outcomes across genotypes were more uniform with more CYP independent PPIs rabeprazole and esomeprazole. Twenty-seven publications on 11 adjunctive medications showed mixed results for adjunctive therapies including nocturnal histamine-2 receptor antagonists, promotility agents, transient lower esophageal sphincter relaxation inhibitors, and mucosal protective agents. Utilizing PPI metabolizer genotype or switching to a CYP2C19 independent PPI is a simple and conservative measure that may be useful in the setting of incomplete acid suppression. The use of adjunctive medications can be considered particularly when the physiologic mechanism for PPI nonresponse is suspected. Future studies using adjunctive medications with improved study design and patient enrollment are needed to better delineate medical management options before proceeding to antireflux interventions.

Project description:Proton pump inhibitors (PPIs) are commonly used to lessen symptoms in patients with gastroesophageal reflux disease (GERD). However, the effects of PPI therapy on the gastrointestinal microbiota in GERD patients remain unclear. We examined the association between the PPI usage and the microbiota present in gastric mucosal and fecal samples from GERD patients and healthy controls (HCs) using 16S rRNA gene sequencing. GERD patients taking PPIs were further divided into short-term and long-term PPI user groups. We showed that PPI administration lowered the relative bacterial diversity of the gastric microbiota in GERD patients. Compared to the non-PPI-user and HC groups, higher abundances of Planococcaceae, Oxalobacteraceae, and Sphingomonadaceae were found in the gastric microbiota from the PPI-user group. In addition, the Methylophilus genus was more highly abundant in the long-term PPI user group than in the short-term PPI-user group. Despite the absence of differences in alpha diversity, there were significant differences in the fecal bacterial composition of between GERD patients taking PPIs and those not taking PPIs. There was a higher abundance of Streptococcaceae, Veillonellaceae, Acidaminococcaceae, Micrococcaceae, and Flavobacteriaceae present in the fecal microbiota from the PPI-user group than those from the non-PPI-user and HC groups. Additionally, a significantly higher abundance of Ruminococcus was found in GERD patients on long-term PPI medication than that on short-term PPI medication. Our study indicates that PPI administration in patients with GERD has a significant effect on the abundance and structure of the gastric mucosal microbiota but only on the composition of the fecal microbiota.

Project description:Objective Clinically, patients with proton pomp inhibitor (PPI)-resistant gastroesophageal reflux disease (GERD) are very challenging to treat. The aim of this study was to determine the rates of symptom relief and adverse events among PPI-resistant GERD patients that changed their therapy from a PPI to vonoprazan. Methods Patients with severe gastroesophageal reflux symptoms (total GERD-Q score ?8) without endoscopic findings of mucosal breaks who changed their medication from a PPI to vonoprazan during a 12-week period from 2015 to 2016 at 2 hospitals were selected. The primary outcome was the self-reported relief of gastroesophageal reflux symptoms. The odds ratio (OR) for the improvement of symptoms was calculated based on an exact binomial distribution using a matched-pair analysis. The secondary outcome was the GERD-Q score and adverse events. Results Twenty-six patients (6 men) with a mean age of 67.5 years were analyzed. After the therapy was changed from a PPI to vonoprazan, 18 patients (69.2%) reported an improvement, 6 (23.1%) reported no change, and 2 (7.7%) reported an exacerbation of symptoms. A change in therapy was significantly associated with improved self-reported symptoms (OR 9.0, p<0.001). The mean total GERD-Q score during vonoprazan treatment was significantly lower than that during PPI therapy (11.96 vs. 8.92). There were no significant differences in the incidence of adverse events between the therapies. Conclusion Changing the medication from a PPI to vonoprazan was significantly associated with an improvement in gastroesophageal reflux symptoms. Vonoprazan is one of the most promising treatment options for patients with PPI-resistant GERD.

Project description:Background/aimsThe economic burden for gastroesophageal reflux disease (GERD) has recently increased in Asian countries. This study investigates the cost-effectiveness between anti-reflux surgery and medication, with proton pump inhibitors (PPIs) for GERD in Korea.MethodsWe used a decision tree and Markov model to obtain the costs and quality-adjusted life years (QALYs) of the surgical and medical strategies. Our target cohort was the severe GERD patients aged 50 years old who required a continuous double dose of PPIs. The time horizon was 10 years and all estimates were discounted at 5% per year. The incremental cost-effectiveness ratio of the anti-reflux surgery compared with medication with PPIs was calculated. Sensitivity analyses were performed on all relevant variables.ResultsThe cost-utility analysis indicated anti-reflux surgery was more cost-effective than medication among severe GERD patients over a 10-year period. The model predicted that the surgical strategy had a cost savings of $551 and the QALYs had a gain of 1.18 as compared with the medical strategy. The break-even point in costs of the anti-reflux surgery over the medication was estimated to be 9 years. Sensitivity analyses using the varying parameter assumptions demonstrated the robustness of the study results.ConclusionsThis study showed anti-reflux surgery was less expensive and more effective therapy over the PPI medication after 9 years of follow-up. This suggests the surgical strategy is a cost-effective alternative to PPI medication among patients who need long-term management for GERD in Korea.

Project description:Non-invasive intermittent positive pressure ventilation can lead to esophageal insufflations and in turn to gastric distension. The fact that the latter induces transient relaxation of the lower esophageal sphincter implies that it may increase gastroesophageal refluxes. We previously reported that nasal Pressure Support Ventilation (nPSV), contrary to nasal Neurally-Adjusted Ventilatory Assist (nNAVA), triggers active inspiratory laryngeal closure. This suggests that esophageal insufflations are more frequent in nPSV than in nNAVA. The objectives of the present study were to test the hypotheses that: i) gastroesophageal refluxes are increased during nPSV compared to both control condition and nNAVA; ii) esophageal insufflations occur more frequently during nPSV than nNAVA. Polysomnographic recordings and esophageal multichannel intraluminal impedance pHmetry were performed in nine chronically instrumented newborn lambs to study gastroesophageal refluxes, esophageal insufflations, states of alertness, laryngeal closure and respiration. Recordings were repeated without sedation in control condition, nPSV (15/4 cmH2O) and nNAVA (~ 15/4 cmH2O). The number of gastroesophageal refluxes recorded over six hours, expressed as median (interquartile range), decreased during both nPSV (1 (0, 3)) and nNAVA [1 (0, 3)] compared to control condition (5 (3, 10)), (p < 0.05). Meanwhile, the esophageal insufflation index did not differ between nPSV (40 (11, 61) h-1) and nNAVA (10 (9, 56) h-1) (p = 0.8). In conclusion, nPSV and nNAVA similarly inhibit gastroesophageal refluxes in healthy newborn lambs at pressures that do not lead to gastric distension. In addition, the occurrence of esophageal insufflations is not significantly different between nPSV and nNAVA. The strong inhibitory effect of nIPPV on gastroesophageal refluxes appears identical to that reported with nasal continuous positive airway pressure.
