Review
Esophageal disorders are prevalent among patients with chronic lung diseases, including idiopathic pulmonary fibrosis (IPF). Gastroesophageal reflux disease (GERD) has been associated with IPF prevalence, severity, and respiratory decline. The pathophysiologic relationship between GERD and IPF is likely bidirectional, with aspiration of refluxate leading to lung inflammation and fibrosis, while the restrictive pulmonary physiology may contribute to altered transdiaphragmatic pressure gradient and increased reflux. Esophageal symptoms are frequently absent and do not predict esophageal dysfunction or pathologic reflux in patients with IPF, and objective diagnostic tools including upper endoscopy, ambulatory reflux monitoring, and high-resolution manometry are often needed. Impedance-based testing that identifies both weakly/non-acidic and acid reflux may provide important additional diagnostic value beyond pH-based acid testing alone. Novel metrics and maneuvers, including advanced impedance measures on impedance-pH study and provocative testing on HRM, may hold promise to future diagnostic advancements. The main treatment options include medical therapy with acid suppressants and anti-reflux surgery, although their potential benefits in pulmonary outcomes of IPF require further validations. Future directions of research include identifying phenotypes of IPF patients who may benefit from esophageal testing and treatment, determining the optimal testing strategy and protocol, and prospectively assessing the value of different esophageal therapies to improve outcomes while minimizing risks. This review will discuss the pathophysiology, evaluation, and management of esophageal diseases, particularly GERD, in patients with IPF, as informed by the most recent publications in the field, in hopes of identifying targets for future study and research.

Review
Gastroesophageal reflux disease (GERD) is a very prevalent condition and has a high impact on the quality of life. Nevertheless, pathophysiology is complex and multi-factorial. Several mechanisms have been proposed: decreased salivation, decreased lower esophageal sphincter pressure resting tone, presence of hiatal hernia, increased number of transient lower esophageal sphincter relaxations, increased acid, and pepsin secretion, duodeno-gastro-esophageal reflux of bile acids and trypsin. Other factors contributing to the pathophysiology of GERD include poor esophageal clearance, delayed gastric emptying and impaired mucosal defensive factors. Esophageal mucosa integrity is impaired both in patients with erosive esophagitis also in regions macroscopically normal and in NERD patients. Patients with functional heartburn have instead a normal mucosal integrity. The mechanisms underlying extra-esophageal GERD are instead more controversial. Reflux symptoms could be caused by esophageal hypersensitivity as a result of visceral neural pathway dysfunction. Multiple mechanisms influence the perception of GERD symptoms, such as the acidity of the refluxate, its proximal extent, the presence of gas in the refluxate, duodeno-gastro-esophageal reflux, mucosal integrity, and peripheral and central sensitization. Furthermore several risk factors can influence the onset of GERD and its complications such as life style, obesity, genetics, pregnancy, and stress. In particular obesity is associated with complications related to longstanding reflux such as erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. Understanding the pathophysiology of gastro-esophageal reflux is important for future targets for therapy. Further research is necessary to improve the current knowledge of the contributing factors leading to GERD.

Review
Proton pump inhibitors (PPIs), the most commonly used antisecretory medi-cations in the management of reflux illness, virtually eliminate elective surgery for ulcer disease, and relegate anti-reflux surgery to patients with gastroesophageal reflux disease (GERD) who are inadequately managed by medical therapy. However, PPI medications still leave some therapeutic demands of GERD unmet. Furthermore, up to 40%-55% of daily PPI users have chronic symptoms, due to PPI refractoriness. Potassium-competitive acid blockers (P-CABs) transcend many of the problems and limits of PPIs, delivering quick, powerful, and extended acid suppression and allowing for treatment of numerous unmet needs. Recently, it has become clear that compromised mucosal integrity plays a role in the etiology of GERD. As a result, esophageal mucosal protection has emerged as a novel and potential treatment approach. An increasing body of research demonstrates that when P-CABs are used as primary drugs or add-on drugs (to regular treatment), they provide a considerable extra benefit, particularly in alleviating symptoms that do not respond to PPI therapy.

Meta-Analysis Review
20 mg of vonoprazan (VPZ20) is recommended in most countries to treat erosive esophagitis (EE). Whether other doses of vonoprazan, such as 5 mg (VPZ5), 10 mg (VPZ10), 20 mg (VPZ20), and 40 mg (VPZ40) are more effective is unknown. Three databases were electronically searched to identify studies published before November 2021. Network meta-analysis was performed using STATA 14.0. VPZ20 and VPZ40 were comparable to PPI, VPZ5 and VPZ10 in 4- and 8-week healing rates, and this was also detected in patients with refractory EE. All regimens resulted in similar treatment-emergent adverse events (TEAEs). However, VPZ40 ranked first for healing rate and TEAEs; however, VPZ20 ranked worst for TEAEs. Different doses of VPZ are comparable in efficacy and safety, but VPZ40 may be best in both effectiveness and safety.

Review
Eradication of Helicobacter pylori causes improvement of gastric atrophy and intestinal metaplasia. Gastric acid secretion levels in corpus predominant gastritis increase after eradication. These changes can increase the risk of reflux esophagitis and low-dosage aspirin ulcers. Although eradication may reduce the overall risk of gastric cancer, a certain degree of risk remains, related to the extent of atrophy and intestinal metaplasia. Many post-eradication gastric cancers are the early depressed type, with low levels of epithelial atypia, and therefore can be difficult to distinguish endoscopically from benign erosion. Further research is required in this area.

Review
Obesity is associated with gastroesophageal reflux disease (GERD) and its complications including reflux esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. Traditionally, these associations have been attributed to the mechanical effect of abdominal fat in increasing intra-abdominal pressure, thereby promoting gastroesophageal reflux and causing disruption of antireflux mechanisms at the esophagogastric junction. However, recent studies suggest that visceral adipose tissue (VAT) produces numerous cytokines that can cause esophageal inflammation and impair esophageal mucosal barrier integrity through reflux-independent mechanisms that render the esophageal mucosa especially susceptible to GERD-induced injury. In this report, we review mechanisms of esophageal mucosal defense, the genesis and remodeling of visceral adipose tissue during obesity, and the potential role of substances produced by VAT, especially the VAT that encircles the esophagogastric junction, in the impairment of esophageal mucosal barrier integrity that leads to the development of GERD complications.

Observational Study
The similarities and differences between acute esophageal necrosis and severe reflux esophagitis have not been elucidated. We compared Los Angeles classification Grade C reflux esophagitis, Grade D reflux esophagitis, and acute esophageal necrosis to consider the similarities and differences between acute esophageal necrosis and severe reflux esophagitis.We retrospectively reviewed records of patients who underwent esophagogastroduodenoscopy at a tertiary referral center from January 2012 to December 2019. Data on patients diagnosed as Grade C reflux, Grade D reflux, or acute esophageal necrosis for the first time were extracted for analysis.A total of 213 patients were enrolled in the study, composed of 130 Grade C reflux, 74 Grade D reflux, and 9 acute esophageal necrosis patients. Compared to Grade C reflux patients, Grade D reflux and acute esophageal necrosis patients were more likely to be transfused (P = .013 and P = .011, respectively), to have duodenal ulcers (P = .025 and P = .049, respectively), and to have psychiatric illnesses (P = .022 and P = .018, respectively). Compared to both Grade C and D reflux, acute esophageal necrosis patients were more likely to present with shock (P = .003 and P < .001, respectively), have type 1 diabetes (P = .030 and P = .004, respectively), and present in winter (P < .001 and P < .001, respectively). Significant step-wise differences (Grade C < Grade D < acute esophageal necrosis) were observed in the need for admission (P < .001 and P = .009), coffee ground emesis (P < .001 and P = .022), and stigmata of hemorrhage on endoscopy (P = .002 and P < .001). Admission (P = .003) and coffee ground emesis (P = .003) independently predicted either Grade D reflux or acute esophageal necrosis over Grade C reflux on multivariate analysis.Shock, type 1 diabetes, and winter may predict acute esophageal necrosis, while the need for admission and coffee ground emesis may predict Grade D reflux or acute esophageal necrosis.

Minerva Pediatrics Jun 2021Our aim is to determine the incidence of reflux in children older than 3 years requiring adenotonsillectomy and relationship between GER and diagnostic tests.
BACKGROUND
Our aim is to determine the incidence of reflux in children older than 3 years requiring adenotonsillectomy and relationship between GER and diagnostic tests.
METHODS
Forty-four patients, who were listed for adenoidectomy/tonsillectomy at Pediatric Ear Nose Throat department due to severe hypertrophy, were evaluated for accompanying GER (Group 1). GER was diagnosed as having at least one positive GER test result (including esophagitis or pH monitoring). Twenty children without reflux symptoms were used as healthy control group (Group 2) and LPR was held.
RESULTS
Reflux was detected in 32 children requiring adenotonsillectomy (72.7%). LPR score was negative in all patients in Group 2. There was no correlation between pH monitoring and histopathological evaluation of esophagus. There was a correlation between the LPR score and histological esophagitis in the proximal esophagus.
CONCLUSIONS
GER was high in patients with adenotonsillary hypertrophy. LPR score and the history of patients are as effective as invasive techniques like pH monitorization and endoscopy in determining GER disease.

Review
INTRODUCTION
Gastroesophageal reflux disease (GERD) is a very common worldwide condition, affecting about 15-20% of the whole population, and representing a major burden for health-care systems. Because of its frequency, health physicians - family doctors as well as specialists - should be aware of the different pharmacotherapeutic approaches in managing GERD, according to disease severity.
AREAS COVERED
Authors summarize the pharmacological management of GERD in adults, present the different pharmaceutical classes, and review the evidence on efficacy for each treatment according to the most common clinical scenarios: non-erosive gastroesophageal reflux disease (NERD), erosive esophagitis (EE), and proton-pump inhibitor (PPI) refractory GERD. They also provide an overview of treatments under development.
EXPERT OPINION
To date, PPIs remain the most effective treatment option for both NERD and EE. However, Potassium-Competitive Acid blockers (PCAB) may be considered, with at least similar efficacy in Asian populations. Preliminary data suggest that PCABs could be superior to classic PPIs in patients with severe EE, and may also be of particular interest in the management of PPI-refractory GERD patients. Their definitive role in GERD management, however, still remains to be determined based on properly designed and conducted randomized clinical trials.

Review
Esophagitis is the end result of a variety of insults to epithelial homeostasis. Eosinophilic esophagitis is a manifestation of non-IgE-mediated food allergy that most commonly affects the esophagus of males who have other atopic phenomena. Reflux esophagitis reflects repeated exposure to acidic gastric contents because of failure of the normal protections afforded by the LES. Because certain histologic features can be present in either condition, endoscopic biopsy alone does not distinguish them. Their symptoms overlap, but the treatment options are very different, such that making a formal diagnosis by following consensus guidelines is essential. A treatment protocol designed to manage the inflammation by controlling the provocative factors (acid for GERD and food antigens for EoE) or suppressing the inflammation (ie, topical steroids for EoE) should result in normalization of the mucosa and resolution of symptoms. Eosinophilic esophagitis is a chronic condition that rarely remits spontaneously, so any therapeutic modality will need to be continued indefinitely.
