Abstract
Reflux hypersensitivity (RH) is a subtype of gastroesophageal reflux disease. The Rome IV criteria separated RH from the original nonerosive reflux disease subgroup and classified it as a new functional oesophageal disease. Recently, the pathogenesis of RH has become the focus of research. According to the latest research reports, upregulation of acid-sensitive receptors, distribution of calcitonin gene-related peptide-positive nerve fibres, and psychiatric comorbidity have key roles in the pathogenesis of RH. This work reviews the latest findings regarding RH mechanisms.

Abstract
INTRODUCTION Despite the high prevalence of typical symptoms of gastroesophageal reflux disease (GERD), approximately 30% of patients have functional esophageal disorders (FED) on ambulatory reflux monitoring, which may include reflux hypersensitivity (RH; defined as physiologic acid exposure but temporally correlated symptoms of reflux), or functional heartburn (FH; defined as physiologic acid exposure and negative symptom correlation). There are limited epidemiological data characterizing these conditions. We investigated demographic and socioeconomic factors as well as medical comorbidities which may predispose to FED versus pathologic GERD. METHODS Adult patients with reflux symptoms for at least 3 months were studied with 24-h pH-impedance testing from 11/2019 to 3/2021. Participants were categorized into pathologic GERD, FH, or RH using pH-impedance data and reported symptom correlation. Demographic data, including age, gender, race/ethnicity, zip code, insurance status, and medical comorbidity data were retrospectively retrieved from the electronic medical record on all participants. RESULTS 229 patients were included. Non-Hispanic Asian ethnicity (OR 5.65; p = 0.01), underweight BMI (OR 7.33; p = 0.06), chronic pain (OR 2.33; p < 0.01), insomnia (OR 2.83; p = 0.06), and allergic rhinitis (OR 3.90; p < 0.01) were associated with a greater risk for FED. Overweight BMI (OR 0.48; p = 0.03) and alcohol use (OR 0.57; p = 0.06) were associated with a decreased risk for FED. DISCUSSION This is the first report of a greater risk of FED in patients with underweight BMI, insomnia, chronic pain, allergic rhinitis, or of Asian or Hispanic ethnicities. The weak associations between female gender and anxiety are corroborated in other studies. Our findings enable clinicians to better screen patients with reflux for this disorder.

Abstract
Reflux hypersensitivity (RH) is one of the phenotypes of gastroesophageal reflux disease. The latest Rome IV defines RH as a condition with typical reflux symptoms and positive reflux-symptom association despite normal acid exposure. Subsequently, the Lyon consensus proposed detailed cutoff values for the criteria on the basis of experts' consensus. Rome IV brought a clear-cut perspective into the pathophysiology of gastroesophageal reflux disease and the importance of esophageal hypersensitivity. This perspective can be supported by the fact that other functional gastrointestinal disorders such as irritable bowel syndrome and functional dyspepsia often overlap with RH. Although several possible pathophysiological mechanisms of esophageal hypersensitivity have been identified, there is still unmet medical needs in terms of treatment for this condition. This review summarizes the current knowledge regarding RH.

Abstract
Background/Aims Since available data on pediatric non-erosive esophageal phenotypes (NEEPs) are scant, we investigated their prevalence and the phenotype-dependent treatment response in these children. Methods Over a 5-year period, children with negative upper endoscopy, who underwent esophageal pH-impedance (off-therapy) for persisting symptoms not responsive to proton pump inhibitor (PPI)-treatment, were recruited. Based on the results of acid reflux index (RI) and symptom association probability (SAP), patients were categorized into: (1) abnormal RI (non-erosive reflux disease [NERD]), (2) normal RI and abnormal SAP (reflux hypersensitivity [RH]), (3) normal RI and normal SAP (functional heartburn [FH]), and (4) normal RI and not-reliable SAP (normal-RI-not otherwise-specified [normal-RI-NOS]). For each subgroup, treatment response was evaluated. Results Out of 2333 children who underwent esophageal pH-impedance, 68 cases, including 18 NERD, 14 RH, 26 FH, and 10 normal-RI-NOS were identified as fulfilling the inclusion criteria and were analyzed. Considering symptoms before endoscopy, chest pain was more reported in NERD than in other cases (6/18 vs 5/50, P = 0.031). At long-term follow-up of 23 patients (8 NERD, 8 FH, 2 RH, and 5 normal-RI-NOS): 17 were on PPIs and 2 combined alginate, 1 (FH) was on benzodiazepine + anticholinergic, 1 (normal-RI-NOS) on citalopram, and 3 had no therapy. A complete symptom-resolution was observed in 5/8 NERD, in 2/8 FH, and in 2/5 normal-RI-NOS. Conclusions FH may be the most common pediatric NEEP. At long-term follow-up, there was a trend toward a more frequent complete symptom resolution with PPI-therapy in NERD patients while other groups did not benefit from extended acid-suppressive-treatment.

Abstract
Gastroesophageal reflux disease (GERD) is a common gastrointestinal disorder. High-resolution esophageal manometry (HREM) and 24-h pH study help to properly evaluate GERD patients. The aim of the present study was to classify patients with refractory GERD symptoms into various groups based on endoscopic and physiological testing. The present study is a retrospective analysis of patients referred for HREM and 24-h pH recording between 2019 and 2021. We included all adult patients (age > 18 years) who were referred for evaluation of refractory GERD symptoms. Upper gastrointestinal endoscopy findings, HREM, and 24-h pH findings were noted. Patients were divided into erosive reflux disease (ERD), non-erosive reflux disease (NERD), reflux hypersensitivity (RH), and functional heartburn (FH) based on test results. Demographic details and HREM parameters were compared in the four groups. Statistics used are one-way analysis of variance (ANOVA) and Chi-squared tests. A p-value of <0.05 was considered statistically significant. A total of 144 patients were included-NERD (56, 38.9%), ERD (42, 29.2%), RH (28, 19.5%), and FH (18, 12.5%). Age (p 0.74), and sex distribution (p 0.47), and symptom profile (p 0.12) were similar. The presence of type 2/3 esophagogastric junction (EGJ) morphology was commoner in ERD and NERD (p <0.001). Moreover, the esophagogastric junction contractile integral (EGJ-CI) and basal inspiratory pressures were significantly lower in these two groups (p<0.05). EGJ-CI was low in 32 cases of ERD (76.2%), 41 cases with NERD (73.2%), 7 cases with RH (25%), and 3 cases with FH (16.7%), respectively (p-value < 0.00001). FH and RH account for 32% of cases with refractory GERD symptoms. Impaired EGJ function was more common in ERD and NERD patients compared to FH and RH patients.

Abstract
BACKGROUND/PURPOSE There is scarcity of data on prevalence, overlap, and risk factors for functional gastrointestinal disorders (FGID) by Rome IV criteria. We evaluated these factors among medical, nursing, and humanities students. METHODS Rome IV Diagnostic Questionnaire (for all FGIDs), Rome III questionnaire (for irritable bowel syndrome [IBS], functional diarrhea [FDr], and functional constipation [FC]), and questionnaires assessing demography, physical activity, anxiety, and depression were used. RESULTS A total of 1309 college students were included (medical 425, nursing 390, humanities 494; mean age 20.5 ± 2.1 years; 36.5% males). Prevalence of Rome IV FGIDs was 26.9% (n = 352), significantly higher among females compared with males (32.3% vs. 17.6%; p < 0.001) and significantly higher among medical (34.4%) and nursing students (29.2%) compared with humanities students (18.6%) (p < 0.05). Most common FGIDs were functional dyspepsia (FD) (15.2%), IBS (6.2%), reflux hypersensitivity (3.5%), FDr (2.9%), FC (2.1%), and unspecified functional bowel disorder (2.1%). FGID overlap was present in 9.3%, most common being FD-IBS overlap (4.4%). With Rome III criteria, prevalence of IBS was higher (9.5%), while that of FDr (0.92%) and of FC (1.3%) were lower. On multivariate analysis, independent predictors for FGIDs were female gender, medical student, non-vegetarian diet, junk food, tea/coffee, poor physical activity, anxiety, and insomnia. CONCLUSION Rome IV FGIDs were present among one-fourth of college students with preponderance among females and medical students. FD, IBS, and reflux hypersensitivity were the most common FGIDs. Rome IV criteria led to a reduction in IBS prevalence and increase in FDr and FC prevalence. Dietary factors, physical activity, anxiety, and insomnia affected FGID prevalence.

Abstract
The most recent iteration of the classifications for functional esophageal disorders, Rome IV, proposed relevant modifications of the previous definitions for Rome III. They specifically considered increased esophageal acid exposure as the marker of gastroesophageal reflux disease (GERD), including the remaining part of non-erosive reflux disease patients with normal acid in the group with functional alterations, considering both reflux hypersensitivity and functional heartburn. However, recent pathophysiological and therapeutic data suggest the need for a return to including reflux hypersensitivity in the GERD spectrum. Indeed, physiologic alterations in esophageal mucosal integrity and chemical clearance, the presence of microscopic esophagitis, and strict symptom-reflux association support the concept that reflux hypersensitivity pertains to GERD. Surgical anti-reflux therapy has resulted in positive outcomes, even in the long term, in patients with reflux hypersensitivity and not in those with functional heartburn. Moreover, clinical trials using neuromodulators have been scarce and provided conflicting results. As a result, the real progress of the Rome IV classifications is in dispute. This article aims to summarize the most recent knowledge of non-erosive reflux disease and reflux hypersensitivity to discuss the utility of Rome IV criteria in the identification and management of functional esophageal disorders.

Abstract
Despite the exceptional efficacy of proton pump inhibitors (PPIs) in healing reflux esophagitis complicating gastroesophageal reflux disease (GERD), up to 40% of patients who take PPIs for GERD complain of persistent GERD symptoms. There is no clear consensus on the type, dosing, and duration of PPI therapy required to establish a diagnosis of PPI-refractory GERD symptoms, but most authorities do not consider patients "PPI-refractory" unless they have been on double-dose PPIs. This article discusses the mechanisms that might underlie heartburn that does not respond PPIs and an approach to the management of patients with PPI-refractory GERD symptoms.

Abstract
PURPOSE OF REVIEW Proton pump inhibitors (PPIs) are effective for many conditions but are often overprescribed. Recent concerns about long-term risks have made patients re-evaluate their need to take PPIs chronically, though these population-based studies have methodological weaknesses. The goal of this review is to provide evidenced-based strategies for discontinuation of PPI therapy. RECENT FINDINGS Given that some patients experience rebound symptoms when abruptly stopping continuous PPI therapy due to its effect on hypergastrinemia, strategies focus on avoiding rebound. Tapering the PPI and then initiating a "step-down" approach with the use of alternative medications may be effective. "On-demand therapy" provides patients with the option to take intermittent PPI courses, reducing overall use and cost while preserving patient satisfaction. It is important for providers to consider ambulatory pH or pH/impedance testing to rule out diagnoses that may require alternative medications like neuromodulators. A number of studies reviewed here can provide guidance in counseling patients on PPI discontinuation. It is important for the provider to obtain a baseline needs assessment for PPI therapy and to elucidate predictors of difficulty in discontinuation prior to initiating a strategy.

Abstract
Reflux hypersensitivity, recently introduced by Rome IV as a new functional esophageal disorder, is currently considered as the presence of typical heartburn symptoms in patients with normal upper endoscopy and esophageal biopsies, normal esophageal pH test and with evidence of a close correlation between patients’ heartburn and reflux events. Reflux hypersensitivity is very common and together with functional heartburn accounts for more than 90% of the heartburn patients who failed treatment with proton pump inhibitor twice daily. In addition, reflux hypersensitivity affects primarily young to middle aged women, commonly overlaps with another functional gastrointestinal disorders, and is often associated with some type of psychological comorbidity. Diagnosis is made by using endoscopy with esophageal biopsies, pH-impedance, and high-resolution esophageal manometry. Reflux hypersensitivity is primarily treated with esophageal neuromodulators, such as tricyclic anti-depressants and selective serotonin reuptake inhibitors among others. Surgical anti-reflux management may also play an important role in the treatment of reflux hypersensitivity.
