Abstract
BACKGROUND The prevalence of duodenogastroesophageal reflux (DGER) and its effect on symptoms and oesophageal lesions in gastroesophageal reflux disease (GERD) is unclear. AIMS To conduct a systematic review to determine the prevalence of DGER among patients with GERD, the effect of DGER on symptoms and oesophageal lesions, and the treatment of DGER. METHODS We searched Pubmed and MEDLINE for full text, English language articles until October 2020 that evaluated DGER prevalence among patients with GERD, the effect of DGER on symptoms and oesophageal lesions, and the treatment of DGER. RESULTS We identified 3891 reports and included 35 which analysed DGER prevalence in GERD, 15 which evaluated its effect in non-erosive reflux disease (NERD), 17 on erosive oesophagitis, 23 in Barrett's, and 13 which evaluated the treatment of DGER. The prevalence of DGER, when evaluated by Bilitec, among all GERD patients ranged from 10% to 97%, in NERD 10%-63%, in erosive oesophagitis 22%-80% and in Barrett's 50%-100%. There were no differences in the presence or degree of DGER among patients who were asymptomatic or symptomatic on proton pump inhibitors (PPI). The most commonly evaluated treatments for DGER were PPIs and DGER reduced post-PPI therapy in all studies. CONCLUSIONS The prevalence of DGER increased with more advanced oesophageal lesions and did not explain persisting symptoms among patients taking PPI therapy. PPIs appear to be effective in the treatment of DGER. DGER remains an important consideration in patients with GERD and future therapies deserve more study.

Gastro-esophageal reflux disease (GERD) after peroral endoscopic myotomy (POEM). Surg Endosc 2021; 36:3308-3316. [PMID: 34327547 DOI: 10.1007/s00464-021-08644-2] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Accepted: 07/16/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Peroral endoscopic myotomy (POEM) is gaining traction as a minimally invasive treatment of achalasia. Increased reflux is reported after POEM but the incidence, type and severity of reflux are not fully understood. We aimed to study the prevalence and nature of reflux after POEM and correlate reflux with endoscopy and pH-impedance findings. METHODS This is a prospective cohort study of achalasia patients undergoing POEM since 2014. Data from Eckardt and GERD symptom scores, high-resolution oesophageal manometry (HRM) and gastroscopy were performed pre-procedure and repeated at 1-year follow-up. Data from 24-h pH-impedance, if performed, were also recorded. A standardized questionnaire was used to determine the severity and frequency of heartburn symptoms and the composite score for each patient was calculated. RESULTS 58 patients underwent POEM between January 2014 and October 2018. The efficacy of POEM at 1 year was 93.0%. We observed reduction of median Integrated Relaxation Pressure (IRP) from 23.5 ± 33.1 mmHg to 13.4 ± 7.71 mmHg (p = 0.005) and mean Eckardt score improved from 6.09 ± 2.43 points to 1.16 ± 1.70 points (p < 0.001). At 1 year, 43.1% (n = 25) had symptomatic reflux. Of the 40 patients who underwent repeated gastroscopy, 60.0% (n = 24) had endoscopic evidence of oesophagitis with seven patients (18%) diagnosed with Grade C or D oesophagitis. 43.1% (n = 25) of patients had pH-impedance done post-POEM off PPIs. 14 patients (56%) had increased acid exposure. Sixteen percent of reflux episodes were acidic and 77.3% were weakly acidic. CONCLUSION POEM was an effective treatment for achalasia. However, GERD was common after POEM with incidence of 43% on symptom score, 60% on endoscopy and 56% on pH-impedance test. Post-POEM reflux appeared to be predominantly acidic in nature. Routine surveillance for GERD after POEM is recommended.

Abstract
This relationship between gastroesophageal reflux and airway disorders is complex, possibly bidirectional, and not clearly defined. The tools used to investigate gastroesophageal reflux are mostly informative about involvement of gastroesophageal reflux within the gastrointestinal tract, although they are often utilized to study the relationship between gastroesophageal reflux and airway issues with are suspected to occur in relation to reflux. These modalities often lack specificity for reflux-related airway disorders. Co-incidence of gastroesophageal reflux and airway disorders does not necessarily infer causality. While much of our focus has been on managing acidity, controlling refluxate is an area that has not been traditionally aggressively pursued. Our management approach is based on some of the evidence presented, but also often from a lack of adequate study to provide further guidance.

Abstract
Gastroesophageal reflux disease is a common clinical entity in Western societies. Its association with hiatal hernia has been well documented; however, the comparative clinical profile of patients in the presence or absence of hiatal hernia remains mostly unknown. The aim of the present study was to delineate and compare symptom, impedance, and manometric patterns of patients with and without hiatal hernia. A cumulative number of 120 patients with reflux disease were enrolled in the study. Quality of life score, demographic, symptom, manometric, and impedance data were prospectively collected. Data comparison was undertaken between patients with and without hiatal hernia. A P-value < 0.05 was considered statistically significant. Patients with hiatal hernia tended to be older than patients without hernia (52.3 vs. 48.6 years, P < 0.05), whereas quality of life scores were slightly better for the former (97.0 vs. 88.2, P= 0.005). Regurgitation occurred more frequently in patients without hiatal hernia (78.3% vs. 93.9%, P < 0.05). Otherwise, no differences were found with regard to esophageal and extraesophageal symptoms. However, lower esophageal sphincter pressures (7.7 vs. 10.0 mmHg, P= 0.007) and more frequent reflux episodes (upright, 170 vs. 134, P= 0.01; supine, 41 vs. 24, P < 0.03) were documented for patients with hiatal hernia on manometric and impedance studies. Distinct functional characteristics in patients with and without hiatal hernia may suggest a tailored therapeutic management for these diverse patient groups.

Abstract
Immune-mediated injury by the protease-activated receptor-2-interleukin-8 (PAR-2-IL8) pathway may underlie the development of gastroesophageal reflux disease (GERD). However, the localization of PAR-2 and the mechanism of PAR-2 activation remain unclear. This study aimed to address these questions on an esophageal stratified squamous epithelial model and in the human esophageal mucosa of GERD patients. Normal human esophageal epithelial cells were cultured with the air-liquid interface system to establish the model. SLIGKV-NH2 (PAR-2 synthetic agonist), trypsin (PAR-2 natural activator), and weak acid (pH 4, 5, and 6) were added to either the apical or basolateral compartment to evaluate their effects on transepithelial electrical resistance (TEER) and IL-8 production. PAR-2 localization was examined both in the cell model and biopsies from GERD patients by immunohistochemistry. Apical trypsin stimulation induced IL-8 accompanied by decreased TEER in vitro, whereas the effective concentration from the basolateral side was 10 times lower. SLIGKV-NH2 from basolateral but not apical stimulation induced IL-8 production. Apical weak acid stimulation did not influence TEER or IL-8 production. Immunohistochemistry showed intense reactivity of PAR-2 in the basal and suprabasal layers after stimulation with trypsin. A similar PAR-2 reactivity that was mainly located at the basal and suprabasal layers was detected in GERD patients. In conclusion, the activation of the PAR-2-IL-8 pathway probably occurred at the basal and suprabasal layers, while the esophageal epithelial barrier may influence the activation of PAR-2. Under proton pump inhibitor therapy, refluxed trypsin may remain active and be a potential agent in the pathogenesis of refractory GERD.

Abstract
Barrett's esophagus (BE) is the premalignant lesion of esophageal adenocarcinoma (EAC) defined as specialized intestinal metaplasia of the tubular esophagus that results from chronic gastroesophageal reflux. Which patients are at risk of having BE and which are at further risk of developing EAC has yet to be fully established. Many aspects of the management of BE have changed considerably in the past 5 years alone. The aim of this review is to define the critical elements necessary to effectively manage individuals with BE. The general prevalence of BE is estimated at 1.6-3% and follows a demographic distribution similar to EAC. Both short-segment (<3 cm) and long-segment (≥3 cm) BE confer a significant risk for EAC that is increased by the development of dysplasia. The treatment for flat high-grade dysplasia is endoscopic radiofrequency ablation therapy. The benefits of ablation for non-dysplastic BE and BE with low-grade dysplasia have yet to be validated. By understanding the intricacies of the development, screening, surveillance, and treatment of BE, new insights will be gained into the prevention and early detection of EAC that may ultimately lead to a reduction in morbidity and mortality in this patient population.

Abstract
OBJECTIVES The proteinase-activated receptor-2 (PAR-2) is activated by serine proteases and has been demonstrated to induce proinflammatory and neuroinflammatory effects. It is considered to alter transepithelial resistance and mediates visceral hypersensitivity. This study aimed to evaluate the expression of PAR-2 in human esophageal mucosa of patients with gastroesophageal reflux disease (GERD) in relation to mucosal alterations. METHODS The study included 123 patients with GERD stratified to erosive reflux disease (n=50), non-erosive reflux disease (n=46), and reflux-negative patients as controls (n=27). Endoscopic and histopathological characterization was performed according to the Los Angeles classification and modified Ismail-Beigi criteria, respectively. PAR-2 expression was analyzed by quantitative reverse transcription (RT)-PCR and immunohistochemistry. The gene expression levels of interleukin (IL)-8 were determined by quantitative RT-PCR and correlated to PAR-2 expression in each patient. Performing in vitro studies, esophageal squamous cell lines (KYSE 150, KYSE 450) were incubated, adjusted to different pH (7.0, 6.0, and 5.0), and exposed to bile acids and PAR-2-activation peptide (SLIGKV-NH(2)). RESULTS PAR-2 gene expression was 7- to 10-fold upregulated (P<0.0001) in the mucosa of patients with GERD and correlated positively with IL-8 expression and with histomorphological alterations (dilated intercellular spaces, papillary elongation, basal cell hyperplasia (BCH); P<0.01). Immunohistochemistry showed an intense staining of PAR-2 throughout all epithelial layers in patients with GERD compared with controls (P=0.0005). In vitro studies revealed a 1.5- to 20-fold induction of PAR-2 gene expression in esophageal squamous cells by acidified medium (P<0.01), but not by additional bile acids. The activation of PAR-2 leads to expression and secretion of IL-8. CONCLUSIONS This study provides evidence of the functional importance of PAR-2-mediated pathways in the pathogenesis of GERD and GERD-associated mucosal alterations and inflammatory changes.

Abstract
Gastroesophageal reflux disease (GERD) is a common disease in the western world. Usually it occurs with typical symptoms like heartburn and regurgitation, but almost every third GERD-patient presents with extraesophageal symptoms and diseases in which a causal relation with GERD is discussed. The extraesophageal symptoms possibly associated with GERD are chronic cough, bronchial asthma, sleep disturbances including obstructive sleep apnea, hoarseness, dental erosions, non-cardiac chest pain and idiopathic pulmonary fibrosis. This article gives an overview of the reflux-associated diseases of the airways as well as the proposed pathomechanisms and therapeutic options.

Abstract
Most epithelial cancers occur on the background of chronic exposure to damaging agents which is reflected in the long lag phase from development of a pre-invasive lesion to the development of a carcinoma. Luminal refluxate has long been recognized to be associated with Barrett's oesophagus, although causal mechanisms have not been clearly defined. Recently, obesity and dietary nitric oxide have also been implicated in the disease pathogenesis. We have demonstrated that acid can alter cell kinetics and, together with nitric oxide, can induce double-stranded DNA breaks. Aside from exposure to luminal factors, the stromal micro-environment may also be important. There is increasing evidence to suggest that inflammatory pathways such as TGF (transforming growth factor) β may play a role in Barrett's oesophagus carcinogenesis. Hence stromal–epithelial–luminal interactions may influence cell behaviour. As sequelae to this, it is possible that the niches created by the micro-environment may influence genetic epithelial diversity observed within the Barrett's oesophagus segment.

Abstract
Diseases of the upper gastrointestinal tract such as gastroesophageal reflux disease (GERD), peptic ulcer and gastric cancer become more common and more severe with advancing age. Older individuals also tend to have a higher prevalence of co-morbid factors, such as Helicobacter pylori infection, presence of other diseases, or use of medications (e.g., nonsteroidal anti-inflammatory drugs, bisphosphonates) that increase their risk for acid-related disorders. Unfortunately, in the elderly patient with these disorders symptom presentation may be slight or atypical, resulting in a delayed diagnosis. In general, the treatment of older individuals with peptic ulcer or GERD and its complications is similar to that of younger individuals. Proton pump inhibitors are the basis of therapy for symptom relief, healing of erosive esophagitis and peptic ulceration, reduction of the risk for NSAID induced mucosal damage, and prevention of disease relapses. The strongest prevalence of H.pylori infection in the elderly, as well as the role of H.pylori in the occurrence of gastric lesions, in particular ulcer diseases, gastric precancerous lesions and gastric cancer, make the diagnosis and the eradication of H.pylori in this population of the utmost importance. Strategies to improve the management of upper gastrointestinal diseases in older people will reduce mortality and improve quality of life.
