Abstract
We propose a novel algorithm integrating Clinical Achalasia Risk Score (CARS) scoring, functional lumen imaging probe (FLIP) panometry, and wireless pH monitoring to streamline esophageal symptom evaluation during index endoscopy. This approach reduces diagnostic delays and reliance on manometry, diagnosing 50% to 70% of patients without overt findings. CARS scoring assesses achalasia likelihood, guiding and informing FLIP panometry to evaluate esophagogastric junction opening and motility, yielding more accurate classifications, and wireless pH monitoring enhances gastroesophageal reflux disease diagnosis by measuring acid exposure over 48 to 96 hours. This method can diagnose up to 75% of patients within a week.

United European Gastroenterol J 2018; 6:1294-1306.

Abstract
BACKGROUND Patients with persistent gastroesophageal reflux disease symptoms despite proton pump inhibitors are increasingly encountered. It remains controversial if proton pump inhibitors should be stopped before functional oesophageal tests. AIM This meta-analysis compares the positive yield of oesophageal studies performed off versus on proton pump inhibitors. METHODS Pubmed, Embase and the Cochrane Library were searched for eligible studies. Outcomes assessed were the number of subjects with: elevated oesophageal acid exposure time when studied off versus on proton pump inhibitors; positive symptom index (≥50%) and/or positive symptom association probability (≥95%) for acid reflux; and/or non-acid reflux events off versus on proton pump inhibitors. The random effects model was applied. RESULTS Fifteen studies (n = 5033 individuals; 33% on proton pump inhibitors; 32% men; mean age 52.1 years) were analysed. Pooled risk ratio for the comparison of high oesophageal acid exposure time off versus on proton pump inhibitors was 2.16 (95% confidence interval (CI) 1.42-3.28). The risk ratio of a positive symptom index (acid reflux) was 2.64 (95% CI 1.52-4.57) and the risk ratio of a positive symptom association probability (acid reflux) was 2.94 (95% CI 2.31-3.74). Conversely, the risk ratio of a positive symptom index (non-acid reflux) was 0.96 (95% CI 0.49-1.88) and risk ratio of a positive symptom association probability (non-acid reflux) was 0.54 (95% CI 0.30-0.99). CONCLUSIONS Oesophageal studies after proton pump inhibitor cessation improve the positive yield for acid reflux-related events but reduce the detection of symptomatic non-acid reflux events.

Abstract
Management of gastroesophageal reflux disease (GERD) commonly starts with an empiric trial of proton pump inhibitor (PPI) therapy and complementary lifestyle measures, for patients without alarm symptoms. Optimization of therapy (improving compliance and timing of PPI doses), or increasing PPI dosage to twice daily in select circumstances, can reduce persistent symptoms. Patients with continued symptoms can be evaluated with endoscopy and tests of esophageal physiology, to better determine their disease phenotype and optimize treatment. Laparoscopic fundoplication, magnetic sphincter augmentation, and endoscopic therapies can benefit patients with well-characterized GERD. Patients with functional diseases that overlap with or mimic GERD can also be treated with neuromodulators (primarily antidepressants), or psychological interventions (psychotherapy, hypnotherapy, cognitive and behavioral therapy). Future approaches to treatment of GERD include potassium-competitive acid blockers, reflux-reducing agents, bile acid binders, injection of inert substances into the esophagogastric junction, and electrical stimulation of the lower esophageal sphincter.

Abstract
AIM To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice.
METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed.
RESULTS The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients’ GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers (RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers (total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01).
CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

Abstract
BACKGROUND Approximately one-third of gastroesophageal reflux disease (GERD) patients have symptoms resistant to proton pump inhibitor (PPI). We used the high-resolution manometry (HRM) and multichannel intraluminal impedance-pH (MII-pH) monitoring to investigate potential predictors of PPI failure in non-erosive reflux disease (NERD) patients. METHODS One hundred and seventeen NERD patients were included, within which there were 44 PPI failure patients. The symptomatic questionnaire GerdQ, HRM and 24-hour MII-pH monitoring were performed before PPI therapy. PPI failure was defined as persistent reflux symptoms for more than 1 day during the last week on esomeprazole (20 mg twice daily) for continuous 4 weeks. The predictors for PPI failure were investigated by multivariable logistic regression analysis. KEY RESULTS Proton pump inhibitor failure patients had lower body mass index (BMI) and more concomitant functional dyspepsia (FD) symptoms. PPI failure patients had a higher percentage of type I esophagogastric junction (EGJ) morphology (p = 0.005), increased EGJ augmentation (p = 0.000), higher prevalence of esophageal motility disorders (p = 0.005) and a higher ratio of negative symptom index (SI, p = 0.000). Multivariable regression analysis showed that concomitance of FD symptoms, EGJ augmentation and negative SI were independent risk factors for PPI failure in NERD. CONCLUSIONS & INFERENCES Approximately half of PPI failure patients were found to have esophageal motility disorders in HRM. The independent risk factors for PPI failure in NERD were concomitant FD symptoms, increased EGJ augmentation and negative SI.

Abstract
BACKGROUND & AIMS Patients with suspected gastroesophageal reflux disease (GERD) often are treated empirically with proton pump inhibitors (PPIs). Patients whose symptoms are not reduced during the PPI trial are referred for further tests. We investigated whether patients referred for the evaluation of reflux symptoms had GERD. We also aimed to categorize patients with a poor response to PPIs into groups with hypersensitive esophagus or functional heartburn. METHODS We performed a retrospective study, searching a clinical database of patients referred for GERD testing from 2006 through 2011. We collected data on all patients who underwent upper endoscopy, esophageal manometry, and 24-hour pH-impedance monitoring, and were off PPIs for at least 1 week. Evidence of GERD was determined by an abnormal upper endoscopy or 24-hour pH-impedance monitoring. Further categorization was determined by impedance results and the symptom association probability index. RESULTS We identified 221 patients (mean age, 47.6 ± 13.3 y; 56% male; 61% Caucasians); 97% previously had been prescribed PPIs, before they were tested. The patients had erosive esophagitis (n = 21; 10%), nonerosive reflux disease with increased pH (n = 61; 27%), nonerosive reflux disease with abnormal impedance (n = 18; 8%), hypersensitive esophagus (n = 30; 14%), functional heartburn (n = 18; 8%), functional disorders other than heartburn (n = 30; 14%), and undetermined disorders (n = 43; 19%). CONCLUSIONS In a retrospective analysis of 221 patients, roughly half of the patients referred for testing did not have evidence of GERD. Further categorization of patients can help guide diagnosis and management.

Abstract
'Refractory gastroesophageal reflux disease' is one of the most common misnomers in the area of gastroesophageal reflux disease. The term implies reflux as the underlying etiology despite unresponsiveness to aggressive proton pump inhibitor therapy. The term should be replaced with 'refractory symptoms.' We must acknowledge that in many patients symptoms of reflux often overlap with non-GERD causes such as gastroparesis, dyspepsia, hypersensitive esophagus and functional disorders. Lack of response to aggressive acid suppressive therapy often leads to diagnostic testing. In majority of patients these tests are normal. The role of non-acid reflux in this group is uncertain and patients should not undergo surgical fundoplication based on this parameter. In patients unresponsive to acid suppressive therapy GERD is most commonly not causal and a search for non-GERD causes must ensue.

Abstract
INTRODUCTION A multicenter study with a limited sample size found that absence of esophagitis, presence of functional digestive disorders, and overweight were associated with proton pump inhibitors (PPI) failure. AIM To assess clinical and reflux patterns associated with PPI-responsiveness. MATERIALS AND METHODS Patients with typical gastroesophageal reflux disease (GORD) symptoms had 24 hours pH-impedance monitoring off therapy. Responders had <2 days of symptoms per week while on standard-dose/double-dose PPI. Clinical and reflux parameters were considered for analysis. RESULTS A total of 514 patients were included (267 women), 185 patients were considered PPI responders, and 329 were considered nonresponders. In the whole population, the only significant factor in the prediction of responsiveness to PPI at the multivariate analysis was the presence of esophagitis (P=0.028). The factors identified as significant in patients with a pathologic acid exposure (142 patients) in the prediction of responsiveness to PPI were overweight (body mass index >25 kg/m(2)) and the presence of esophagitis (P=0.019 and 0.043, respectively). CONCLUSIONS We confirm that no reflux pattern demonstrated by 24 hours pH-impedance monitoring is associated to PPI response in GORD patients. Presence of esophagitis in the whole population and overweight in patients with pathologic GORD, but not dyspepsia, are strongly associated with PPI-responsiveness.

Abstract
INTRODUCTION Proton pump inhibitors (PPIs) are widely used for the treatment of acid-related diseases such as gastroesophageal reflux disease (GERD). They are recommended by the American College of Gastroenterology for healing erosive esophagitis (EO) and as long-term treatment in patients with healed EO. The available PPIs differ somewhat in their pharmacokinetics and clinical properties, but whether these differences are of clinical relevance is a matter of debate. Some safety concerns have been raised with the use of PPIs, mostly an increased incidence of infectious diseases such as community-acquired pneumonia or Clostridium difficile diarrhea. AREAS COVERED This article explores the results of clinical studies on the pharmacokinetics and pharmacodynamics of esomeprazole , as well as on its clinical efficacy to manage patients with GERD. EXPERT OPINION GERD is a public health concern as its worldwide incidence and associated complications are increasing alongside the exponentially increasing problem of obesity. PPIs are the first pharmacological option because of their efficacy and overall positive risk-to-benefit ratio. Improved efficacy with the use of stereospecific isomers of PPIs, such as esomeprazole, has not yet been convincingly demonstrated. Nevertheless, because of individual experience with former treatment, some patients may report better symptom control when treated with a specific PPI rather than with others.

Abstract
OPINION STATEMENT "Refractory GERD" is one the most common misnomers in the area of gastroesophageal reflux disease. The term implies reflux as the underlying etiology despite unresponsiveness to aggressive, often twice-daily proton pump inhibitor therapy. The term should be replaced with "refractory symptoms." We must acknowledge that in many patients, symptoms of reflux often overlap with non-GERD causes such as gastroparesis, dyspepsia, hypersensitive esophagus, and functional disorders. Lack of response to aggressive acid suppressive therapy often leads to esophagogastroduodenoscopy followed by pH or impedance monitoring. In the majority of patients these tests are normal. The role of non-acid reflux measured by impedance pH testing in this group is uncertain at best and the results from this test alone should not be used to refer patients to surgical fundoplication. In patients unresponsive to acid suppressive therapy, reflux is most commonly not causal and a search for non-GERD causes must ensue.

Abstract
Acid peptic disorders are the result of distinctive, but overlapping pathogenic mechanisms leading to either excessive acid secretion or diminished mucosal defense. They are common entities present in daily clinical practice that, owing to their chronicity, represent a significant cost to healthcare. Key elements in the success of controlling these entities have been the development of potent and safe drugs based on physiological targets. The histamine-2 receptor antagonists revolutionized the treatment of acid peptic disorders owing to their safety and efficacy profile. The proton-pump inhibitors (PPIs) represent a further therapeutic advance due to more potent inhibition of acid secretion. Ample data from clinical trials and observational experience have confirmed the utility of these agents in the treatment of acid peptic diseases, with differential efficacy and safety characteristics between and within drug classes. Paradigms in their speed and duration of action have underscored the need for new chemical entities that, from a single dose, would provide reliable duration of acid control, particularly at night. Moreover, PPIs reduce, but do not eliminate, the risk of ulcers in patients taking NSAIDs, reflecting untargeted physiopathologic pathways and a breach in the ability to sustain an intragastric pH of more than 4. This review provides an assessment of the current understanding of the physiology of acid production, a discussion of medications targeting gastric acid production and a review of efficacy in specific acid peptic diseases, as well as current challenges and future directions in the treatment of acid-mediated diseases.

Abstract
Functional gastrointestinal (GI) disorders are common in the general population. Based on the Rome III classification, these disorders are mutually exclusive disorders keeping the homogeneity of each functional GI disorder in research area. In contrast, many population and clinical studies have reported a considerably high rate of overlap between functional GI disorders. The overlap of functional GI disorders over other intestinal diseases might simply occur by chance due to a highly prevalent disorder. Moreover, functional GI disorders is considered a chronic stable disorder that may wax and wane for several years. However, a recent study about the natural history of functional GI disorders showed substantial transition among functional GI disorders over time. The natural history of functional GI disorders with overlapping other functional GI disorders are still in infancy and better understanding of these will be important in determining the efficacy of future therapeutic interventions.

Abstract
Up to a third of the patients who receive proton pump inhibitor (PPI) once daily will demonstrate lack or partial response to treatment. There are various mechanisms that contribute to PPI failure and they include residual acid reflux, weakly acidic and weakly alkaline reflux, esophageal hypersensitivity, and psychological comorbidity, among others. Some of these underlying mechanisms may coincide in the same patient. Evaluation for proper compliance and adequate dosing time of PPIs should be the first management step before ordering invasive diagnostic tests. Doubling the PPI dose or switching to another PPI is the second step of management. Upper endoscopy and pH testing appear to have limited diagnostic value in patients who failed PPI treatment. In contrast, esophageal impedance with pH testing (multichannel intraluminal impedance MII-pH) on therapy appears to provide the most insightful information about the subsequent management of these patients (step 3). In step 4, treatment should be tailored to the specific underlying mechanism of patient's PPI failure. For those who demonstrate weakly acidic or weakly alkaline reflux as the underlying cause of their residual symptoms, transient lower esophageal sphincter relaxation reducers, endoscopic treatment, antireflux surgery and pain modulators should be considered. In those with functional heartburn, pain modulators are the cornerstone of therapy.

Abstract
BACKGROUND AND AIM There are heterogeneous subgroups among those with heartburn, and data on these individuals are relatively scant. We aimed to evaluate the effect of acid challenge on the segmental contractions of esophageal smooth muscle in endoscopy-negative patients with normal esophageal acid exposure. METHODS High-resolution esophageal manometry (HRM) was performed on 30 endoscopy-negative patients with heartburn accompanied by normal esophageal acid exposure using 10 water swallows followed by 10 acidic pomegranate juice swallows. Patients were classified into functional heartburn (FH) and hypersensitive esophagus (HE) groups based on the results of 24-hr impedance pH testing. HRM topographic plots were analyzed and maximal wave amplitude and pressure volumes were measured for proximal and distal smooth muscle segments. RESULTS The pressure volume of the distal smooth muscle segment in the HE group measured during acidic swallows was higher than during water swallows (2224.1 ± 68.2 mmHg/cm per s versus 2105.6 ± 66.4 mmHg/cm per s, P = 0.027). A prominent shift in the pressure volume to the distal smooth muscle segment was observed in the HE group compared with the FH group (segmental ratio: 2.72 ± 0.08 versus 2.39 ± 0.07, P = 0.005). Manometric measurements during acidic swallows revealed that this shift was augmented in the HE group. The optimal ratio of pomegranate juice swallowing for discrimination of FH from HE was 2.82, with a sensitivity of 88.9% and a specificity of 100%. CONCLUSIONS Hypercontractile response of distal smooth muscle segment to acid swallowing was more prominent in the HE group than the FH group.

Abstract
Refractory gastroesophageal reflux disease may affect up to one-third of the patients that consume proton pump inhibitor (PPI) once daily. Treatment in clinical practice has been primarily focused on doubling the PPI dose, despite lack of evidence of its value. In patients who failed PPI twice daily, medical treatment has been primarily focused on reducing transient lower esophageal sphincter relaxation rate or attenuating esophageal pain perception using visceral analgesics. In patients with evidence of reflux as the direct trigger of their symptoms, endoscopic treatment or antireflux surgery may be helpful in remitting symptoms. The role of psychological interventions, as well as non-traditional therapeutic strategies remains to be further elucidated.

Abstract
Patients with gastro-esophageal reflux disease (GERD) who are not responding to proton pump inhibitors (PPIs) given once daily are very common. These therapy-resistant patients have become the new face of GERD in clinical practice in the last decade. Upper endoscopy appears to have a limited diagnostic value. In contrast, esophageal impedance with pH testing on therapy appears to provide the most insightful information about the subsequent management of these patients. Commonly, doubling the PPI dose or switching to another PPI will be offered to patients who failed PPI once daily. Failure of such therapeutic strategies is commonly followed by assessment for weakly or residual acidic reflux. There is growing information about the potential value of compounds that can reduce transient lower esophageal sphincter relaxation rate. Esophageal pain modulators are commonly offered to patients with functional heartburn although supportive clinical studies are still missing.

Abstract
PURPOSE OF REVIEW Patients with gastroesophageal reflux disease (GERD) who are not responding to proton pump inhibitors (PPIs) given once daily are very common. These therapy-resistant patients have become the new face of GERD in clinical practice in the last decade and presently pose a significant therapeutic challenge to the practicing physician. We reviewed newly accumulated information about the management of PPI failure that has been published over the past 2 years. RECENT FINDINGS There are diverse mechanisms that contribute to the failure of PPI treatment in GERD patients and they are not limited to residual reflux. Some of the causes of PPI failure may coincide in the same patient. Upper endoscopy appears to have limited diagnostic value. In contrast, esophageal impedance with pH testing on therapy appears to provide the most insightful information about the subsequent management of these patients. Commonly, doubling the PPI dose or switching to another PPI will be offered to patients who failed PPI once daily. Failure of such therapeutic strategies is commonly followed by assessment for residual reflux. There is growing information about the potential value of compounds that can reduce transient lower esophageal sphincter relaxations. Esophageal pain modulators are commonly offered to patients with functional heartburn, although supportive clinical studies are still missing. SUMMARY Management of refractory GERD patients remains an important clinical challenge. Recent studies have cemented the value of impedance-pH testing in pursuing proper treatment. Presently, the most promising therapeutic development for this patient population is transient lower esophageal sphincter relaxation reducers.

Gasiorowska A, Poh CH, Fass R. Gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS)--is it one disease or an overlap of two disorders? Dig Dis Sci 2009; 54:1829-34.

Abstract
Up to 79% of IBS patients report gastroesophageal reflux disease (GERD) symptoms, and up to 71% of GERD patients report irritable bowel syndrome (IBS) symptoms. There are two principal hypotheses for the common presence of IBS symptoms in GERD patients. The first theory suggests that GERD and IBS overlap in a significant number of patients. The second theory suggests that IBS-like symptoms are part of the spectrum of GERD manifestation. The first theory is supported by genetic studies and similarities in gastrointestinal sensory-motor abnormalities potentially due to general gastrointestinal disorder of smooth muscle or sensory afferents. The other theory is primarily supported by studies demonstrating improvement of IBS-like symptoms in GERD patients receiving anti-reflux treatment. The close relationship between GERD and IBS could be explained by either GERD affecting different levels of the GI tract or a high overlap rate between GERD and IBS due to similar underlying GI dysfunction.

Acid and non-acid reflux in Japanese patients with non-erosive reflux disease with persistent reflux symptoms, despite taking a double-dose of proton pump inhibitor: a study using combined pH-impedance monitoring. J Gastroenterol 2009; 44:708-12. [PMID: 19434361 DOI: 10.1007/s00535-009-0070-6] [Citation(s) in RCA: 26] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2008] [Accepted: 03/19/2009] [Indexed: 02/04/2023]
Abstract
BACKGROUND Combined multi-channel intra-luminal impedance and pH (Mll-pH) monitoring can detect gastro-esophageal reflux and identify acid and non-acid reflux (NAR) events. It can be used for patients with persistent symptoms who are having proton pump inhibitor (PPI) therapy. The aim of this study is to determine the frequency of acid reflux and NAR and to establish their relationship with persistent reflux symptoms in Japanese patients with non-erosive reflux disease (NERD) who are on a double-dose of PPI therapy. METHODS Thirteen patients with NERD, with persistent reflux symptoms, despite taking PPI at least twice daily, were included in this study. Twenty-four-hour combined Mll-pH monitoring was carried out on all patients and reflux episodes were detected by impedance channels, located at 3, 5, 7, 9, 15 and 17 cm above the lower esophageal sphincter (LES) and classified into acid reflux and NAR, based on pH data from 5 cm above the LES. A positive symptom index (SI) was declared, if at least half of the symptoms were preceded by reflux episodes within 5 min. RESULTS A total of 916 liquid reflux episodes were detected, and a total of 171 symptoms were recorded. Eight (4.7%) of 171 symptoms were related to acid reflux, and 68 (39.8%) were related to NAR. Seven (53.8%) patients had a positive SI and in these seven patients, a total of 79 symptoms were recorded. 5 (6.3%) of the 79 symptoms were related to acid reflux and 44 (55.7%) were related to NAR. CONCLUSIONS Persistent reflux symptoms, in SI-positive patients with NERD on double-dose PPI therapy, are more likely to be associated with primarily non-acid reflux.

Abstract
OBJECTIVES The objective of this study was to compare the degree of esophageal acid exposure and duodenogastroesophageal reflux (DGER) during treatment between gastroesophageal reflux disease (GERD) patients who responded fully to proton pump inhibitor (PPI) once a day and those who failed to respond. METHODS Gastroesophageal reflux disease patients who continued to report symptoms 3 times a week for 3 months while on PPI once a day were assigned to the PPI failure group. GERD patients who were asymptomatic on PPI once a day for 3 months were assigned to the PPI success group. All patients underwent upper endoscopy to assess esophageal mucosal injury. Subsequently, all patients underwent simultaneous 24-h esophageal Bilitec 2000 and pH testing while on treatment. Patients recorded GERD-related symptoms during the test. RESULTS Twenty-four patients were enrolled in the PPI failure group and 23 patients were enrolled in the PPI success group. Endoscopy was normal in 63% of PPI failure patients and 76% of PPI success patients. Abnormal DGER was documented in 82% of PPI success patients vs. 67% of PPI failure patients (P=NS). All pH testing and Bilitec parameters in the PPI failure group were similar to those in the PPI success group (P=NS). Of the 34 GERD symptoms recorded by the PPI failure group, 64% were associated with acid reflux and 41% were associated with DGER (P<0.05). CONCLUSIONS There is no difference in the degree of DGER and acid exposure during treatment between patients who failed to respond and those who achieved complete symptom resolution on PPI once daily. GERD symptoms in the PPI failure group are more commonly associated with acid reflux than with DGER.

Abstract
BACKGROUND A growing number of studies have shown the impact of psychological comorbidities on gastro-oesophageal reflux disease (GERD) patients' symptom reports and healthcare-seeking behaviour. AIM To review the reported relationship between GERD and psychological comorbidity. METHODS Review of the literature on GERD and psychological comorbidity. RESULTS Psychological comorbidity is common among GERD patients and appears to afflict all GERD phenotypes. Sexual and physical abuse is also common in GERD patients. Stress enhances perception of oesophageal acid exposure. Treatment for GERD, especially in those who are not responsive to antireflux treatment, may require further evaluation for psychological comorbidity. CONCLUSIONS Psychological comorbidity is very common in GERD patients and is likely to play an important role in response, or failure of response, to proton pump inhibitor treatment.
