Validity and reliability of the Persian version of the Gastroesophageal Reflux Disease Health-Related Quality of Life questionnaire.

OBJECTIVE: The Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQL) is one of the most widely used questionnaires for assessing typical gastro-oesophageal reflux disease (GORD) symptoms. It is simple, concise, and treatment responsive, yet it has not been validated in the Persian language. This study aimed to translate the GERD-HRQL questionnaire into Persian and assess its validity and reliability. DESIGN: In this cross-sectional validation study, a team of gastroenterologists, general surgeons, and professional translators conducted the forward-backward translation. A gastroenterologist interviewed 10 patients with GORD to insure understandability of the questionnaire. Fifty-four patients with GORD and 60 patients with gastrointestinal complaints other than GORD were enrolled using convenience sampling method. To assess concurrent validity, patients with GORD completed the Persian GERD-HRQL and the WHO Quality of Life Brief Version (WHOQOL-BREF) questionnaires. To assess discriminant validity, GERD-HRQL scores were compared between GORD and non-GORD patients. After 2 weeks, the patients with GORD completed the GERD-HRQL questionnaire again to assess test-retest reliability. The internal consistency was measured using Cronbach's alpha. RESULTS: The mean age of the GORD participants was 36.90±10.44, and the majority were women (78%). All GERD-HRQL domains and total scores exhibited significant negative correlations with WHOQOL-BREF domains (ranging from -0.28 to -0.97). The GERD-HRQL scores were significantly different in GORD and non-GORD patients (p<0.001). Test and retest scores did not show any significant differences (p=0.49). Cronbach's alpha was 0.85. CONCLUSION: The Persian GERD-HRQL questionnaire is valid and reliable and can effectively assess the GORD symptoms in Persian-speaking individuals.

Good clinical practice recommendations for the diagnosis and treatment of gastroesophageal reflux disease. An expert review from the Asociación Mexicana de Gastroenterología.

INTRODUCTION: Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM: The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS: The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS: Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS: An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

Positive effect of deep diaphragmatic breathing training on gastroesophageal reflux-induced chronic cough: a clinical randomized controlled study.

BACKGROUND AND OBJECTIVE: To explore the efficacy of deep diaphragmatic breathing training (DEP) in patients with gastroesophageal reflux-induced chronic cough (GERC). METHODS: A randomized controlled study was conducted involving 60 GERC patients who were divided into the intervention group and the control group (each with 30 patients). Both groups received routine medication treatment for GERC, while the intervention group received DEP training additionally. Both groups were evaluated by cough symptom scores, Hull airway reflux questionnaire (HARQ), gastroesophageal reflux diagnostic questionnaire (GerdQ), generalized anxiety disorder scale-7 (GAD-7), patient health questionnaire-9 (PHQ-9), Pittsburgh sleep quality index (PSQI), the Leicester cough questionnaire (LCQ), as well as capsaicin cough sensitivity testing, B-ultrasound and surface electromyography (sEMG) of the diaphragmatic muscles before and after treatment. The cough resolution rate and changes of the above indictors was compared between the two groups after eight weeks of treatment. RESULTS: After eight weeks of treatment, cough symptoms improved in both groups, but the cough resolution rate in the intervention group of 94% was significantly higher than that in the control group of 77% (χ2 = 6.402, P = 0.041). The intervention group showed significant improvements to the control group in GerdQ (6.13(0.35) VS 6.57(0.77)), GAD-7 (0(0;1) VS 1(0;3)), PSQI (2(1;3) VS 4(3;6)), LCQ (17.19(1.56) VS 15.88(1.92)) and PHQ-9 (0(0;0) VS 0(0;3)) after treatment. Compared to control group, sEMG activity of the diaphragmatic muscle was significantly increased in the intervention group after treatment, measured during DEP (79.00(2.49) VS 74.65 (1.93)) and quiet breathing (72.73 (1.96) VS 67.15 (2.48)). CONCLUSION: DEP training can improve cough symptoms as an adjunctive treatment in GERC patients. TRIAL REGISTRATION: The protocol was registered in February 2, 2022 via the Chinese Clinical Trials Register ( http://www.chictr.org.cn/ ) [ChiCTR2200056246].

Impact of Gender on Gastroesophageal Reflux Disease Complications: Analysis of 27 Million Hospitalizations.

BACKGROUND AND AIMS: Previous studies have reported gender differences in patients with gastroesophageal reflux disease (GERD). These studies have also reported differences based on gender in the rates of complications. In this study, we aim to identify gender disparities in the rates of GERD complications in the United States. METHODS: We queried the 2016-2020 National Inpatient Sample database to identify patients with GERD. Patients with eosinophilic esophagitis or missing demographics were excluded. We compared patient demographics, comorbidities and complications based on gender. Multivariate logistic regression analysis was used to identify the impact of gender on complications of GERD. RESULTS: 27.2 million patients were included in the analysis. Out of them, 58.4% of the hospitalized patients with GERD were female. Majority of the women were White (75%), aged>65 years (57.5%) and were in the Medicare group (64%). After adjusting for confounders, females were noted to have lower odds of esophagitis (aOR=0.85, 95%CI: 0.84-0.86, p<0.001), esophageal stricture (aOR=0.95, 95%CI: 0.93-0.97, p<0.001), Barrett's esophagus (aOR=0.58, 95%CI: 0.57-0.59, p<0.001) and esophageal cancer (aOR=0.22, 95%CI: 0.21-0.23, p<0.001). CONCLUSIONS: Our study confirms the findings of previous literature that females, despite comprising the majority of the study population, had a lower incidence of GERD related complications. Further studies identifying the underlying reason for these differences are required.

[Reflux symptoms and upper abdominal pain: Reflux, Gastritis and whatever could be behind it]. / Sodbrennen und Oberbauchschmerzen: Reflux, Gastritis und was noch infrage kommt.

Reflux symptoms and upper abdominal pain are very common symptoms in general population. Both symptoms are visceral and thus cannot be linked to an organ or a disease. Diagnostic work-up revealed organic disease in up to 30%, when patients present with dyspeptic symptoms. Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) represent the most frequent and important disorders in western countries, when diagnostic work-up is done in patients with reflux symptoms and abdominal pain.

Analyzing the correlation between gastroesophageal reflux disease and anxiety and depression based on ordered logistic regression.

Numerous studies have indicated a connection between psychiatric symptoms, specifically anxiety and depression, and gastroesophageal reflux. However, the precise nature of the link between the severity of gastroesophageal reflux disease and the severity of anxiety and depression remains uncertain. Here, we gathered 24-h pH monitoring data and baseline patient information from a cohort of 518 individuals. Additionally, we evaluated their psychological well-being using the Hospital Anxiety and Depression Scale. The relationship between baseline characteristics and varying degrees of anxiety, depression, and gastroesophageal reflux disease (GERD) was assessed using R software version 4.1.3 and logistic regression models. The findings indicate a statistically significant variation in anxiety levels based on gender, as well as a significant disparity in depression groups when considering age and literacy levels. Kruskal-Wallis test analysis revealed a significant positive correlation between the severity of anxiety and depression and the 24-h pH monitoring results in our patient cohort. As the anxiety and depression levels increased, the rank mean for each examination result also increased. Logistic regression modeling analysis showed that a higher anxiety level was associated with a higher level of GERD. In the presence of mild anxiety, there is a statistically significant association with a higher incidence of GERD with an odds ratio (OR) of 2.64 (95% CI 1.50, 4.64). Similarly, the moderately severe anxiety group also exhibits a causal relationship with an increased GERD incidence, with an OR of 6.84 (95% CI 3.92, 12.17). Additionally, moderate to severe depression is associated with a higher incidence of GERD, with an OR of 2.32 (95% CI 1.23, 4.37). The prevalence of GERD was greater among males compared to females (OR 2.29, 95% CI 1.51-3.49). Additionally, an elevated body mass index (BMI) demonstrated a positive correlation with the susceptibility to GERD (OR 1.07, 95% CI 1.01-1.14). Increasing age may promote the occurrence of GERD in patients. These findings may help to provide a better basis for psychological or pharmacological interventions for GERD patients with psychosomatic symptoms in the future, and provide a reference basis for clinical treatment of the disease.

A systematic review of Sandifer syndrome in children with severe gastroesophageal reflux.

PURPOSE: Sandifer syndrome (SS), which combines gastroesophageal reflux (GER) and a neurological or psychiatric disorder, is an uncommon condition that often takes a long time to diagnosis. We aimed to systematically review available papers regarding SS. METHODS: After presenting our two cases of SS, we systematically reviewed articles published in MEDILINE/PubMed, Cochrane Library, and Web of Science. RESULTS: The meta-analysis included 54 reported cases and 2 of our own cases. Our results showed that all cases achieved symptom improvement with appropriate treatment for GER. Notably, 19 of the 56 cases exhibited anatomical anomalies, such as hiatal hernia and malrotation. Significantly more patients with than without anatomical anomalies required surgery (p < 0.001). However, 23 of the 29 patients without anatomical anomalies (79%) achieved symptom improvement without surgery. Patients who did not undergo surgery had a median (interquartile range) duration to symptom resolution of 1 (1-1) month. CONCLUSION: The primary care providers should keep SS in the differential diagnosis of patients presenting with abnormal posturing and no apparent neuromuscular disorders. Fundoplication may be effective especially for patients with anatomical anomalies or those whose symptoms do not improve after more than 1 month with nonsurgical treatment.

A multidisciplinary approach to identifying and managing heterotopic gastric inlet patches.

INTRODUCTION: Gastric inlet patches are often incidental, but can also be a treatable cause of laryngo-esophageal symptoms. METHODS: We retrospectively reviewed all patients whose gastric inlet patches were diagnosed following assessment for laryngopharyngeal and swallowing symptoms. Improvement following Argon Plasma Coagulation (APC) was assessed using Minimum Clinically-Important Difference methodology combining voice, throat, and swallowing domains. Correlations between APC response and measures of reflux and mucosal barrier integrity, measured during 24-h pH-impedance manometry, were obtained. Proximal and Distal Mean Nocturnal Baseline Impedance (MNBI) values were separately calculated and the novel variable of Mucosal Impedance Gradient was derived as [((Distal MNBI-Proximal MNBI)/((Distal MNBI + Proximal MMBI)/2)) x 100]. KEY RESULTS: Inlet patches were detected in 57 of 651 patients who had Transnasal Panendoscopy (8.7 ± 2.2%). There were 34 males. Mean age was 58 years. Mean duration of symptoms was 2 years. The commonest symptoms were hoarseness (n = 33), throat symptoms (n = 24), and dysphagia (n = 21), respectively. APC was used to ablate patches in 34 patients. Treatment response was 71% at a mean followup of 5.5 months. MIG > - 25% predicted response to APC, with area under the receiver operating characteristic curve of 0.875 (Sensitivity = 81%; Specificity = 100%; p < 0.0001). CONCLUSIONS: Gastric inlet patches are common and under-recognized. They can cause protracted pharyngo-esophageal symptoms. Patch ablation is an effective treatment for carefully selected patients. Optimal patient selection requires multidisciplinary teamwork. Mucosal Impedance Gradient could further refine patient selection.

Obesity and Upper Gastrointestinal Diseases.

Obesity increases gastroesophageal reflux disease through several factors. As a result, Barrett's esophagus, esophageal adenocarcinoma, and gastroesophageal junctional gastric cancer are increasing. Existing studies usually defined obesity by body mass index and analyzed the correlation. Recently, more studies have shown that central obesity is a more important variable in upper gastrointestinal diseases related to gastroesophageal reflux. Studies have reported that weight loss is effective in reducing gastroesophageal reflux symptoms. Obesity also affects functional gastrointestinal diseases. A significant correlation was shown in upper abdominal pain, reflux, vomiting, and diarrhea rather than lower abdominal diseases.

Applying Lyon consensus criteria in the work-up of patients with extra-oesophageal symptoms - A multicentre retrospective study.

BACKGROUND: The diagnosis of gastro-oesophageal reflux disease (GERD) based on otolaryngologist's assessment of laryngoscopic findings remains contentious in terms of sensitivity and specificity. AIMS: To evaluate GERD prevalence, applying Lyon 2.0 Consensus criteria, in patients with extra-oesophageal symptoms undergoing laryngoscopic examination and impedance-pH monitoring. METHODS: In this retrospective assessment, we included 470 patients with extra-oesophageal symptoms, either isolated or combined with typical symptoms, who had been referred to six tertiary Italian Gastroenterology Units between January and December 2020. Of these, 274 underwent 24-h impedance-pH monitoring and laryngoscopy off PPI therapy. GERD diagnosis followed Lyon Consensus 2.0 criteria, incorporating mean nocturnal baseline impedance when pH-impedance monitoring was inconclusive. RESULTS: Laryngoscopic examination revealed pathological findings (predominantly posterior laryngitis) in 71.2% (195/274). GERD was diagnosed in 29.2% (80/274) via impedance-pH monitoring. The prevalence of GERD in patients with positive or negative laryngoscopy was similar (32.3% vs. 21.5%, p = 0.075). No significant difference in proximal reflux occurrences was noted between positive and negative laryngoscopy groups (33.3% vs. 24.1%, p = 0.133). Laryngoscopy demonstrated sensitivity and specificity of 78.8% and 32.0%, respectively, with a positive predictive value (PPV) of 32.3% and negative predictive value (NPV) of 28.4%. In contrast, a threshold of four concurrent laryngoscopic signs, identified in only eight patients, demonstrated a PPV of 93.8% and a NPV of 73.6% (sensitivity 25.4%, specificity 99.2%). CONCLUSION: This study underscores the limited diagnostic accuracy of laryngoscopy, emphasising the necessity of impedance-pH monitoring for confirming GERD diagnoses using Lyon 2.0 criteria in patients with suspected extra-oesophageal symptoms.

Mononuclear cell composition and activation in blood and mucosal tissue of eosinophilic esophagitis.

Introduction: Eosinophilic esophagitis (EoE) is a chronic, inflammatory, antigen-driven disease of the esophagus. Tissue EoE pathology has previously been extensively characterized by novel transcriptomics and proteomic platforms, however the majority of surface marker determination and screening has been performed in blood due to mucosal tissue size limitations. While eosinophils, CD4+ T cells, mast cells and natural killer (NK) T cells were previously investigated in the context of EoE, an accurate picture of the composition of peripheral blood mononuclear cells (PBMC) and their activation is missing. Methods: In this study, we aimed to comprehensively analyze the composition of peripheral blood mononuclear cells and their activation using surface marker measurements with multicolor flow cytometry simultaneously in both blood and mucosal tissue of patients with active EoE, inactive EoE, patients with gastroesophageal reflux disease (GERD) and controls. Moreover, we set out to validate our data in co-cultures of PBMC with human primary esophageal epithelial cells and in a novel inducible mouse model of eosinophilic esophagitis, characterized by extensive IL-33 secretion in the esophagus. Results: Our results indicate that specific PBMC populations are enriched, and that they alter their surface expression of activation markers in mucosal tissue of active EoE. In particular, we observed upregulation of the immunomodulatory molecule CD38 on CD4+ T cells and on myeloid cells in biopsies of active EoE. Moreover, we observed significant upregulation of PD-1 on CD4+ and myeloid cells, which was even more prominent after corticosteroid treatment. With co-culture experiments we could demonstrate that direct cell contact is needed for PD-1 upregulation on CD4+ T cells. Finally, we validated our findings of PD-1 and CD38 upregulation in an inducible mouse model of EoE. Discussion: Herein we show significant alterations in the PBMC activation profile of patients with active EoE in comparison to inactive EoE, GERD and controls, which could have potential implications for treatment. To our knowledge, this study is the first of its kind expanding the multi-color flow cytometry approach in different patient groups using in vitro and in vivo translational models.

[Surgical strategy for hiatal hernias]. / Operative Strategie bei Hiatushernien.

The indications for surgical treatment of hiatus hernias differentiate between type I and types II, III and IV hernias. The indications for a type I hernia should include a proven reflux disease but the indications for surgical treatment of types II, III and IV hernias are mandatory due to the symptoms with problems in the passage of food and due to the sometimes very severe possible complications. The primary aims of surgery are the repositioning of the herniated contents and a hiatoplasty, which includes a surgical narrowing of the esophageal hiatus by suture implantation. In addition, depending on the clinical situation other procedures, such as hernia sac removal, mesh implantation, gastropexy and fundoplication can be considered. There are various approaches to the repair, all of which have individual advantages and disadvantages. An adaptation to the specific needs situation of the patient and the expertise of the surgeon is therefore essential.

GERD after Bariatric Surgery: A Review of the Underlying Causes and Recommendations for Management.

PURPOSE OF REVIEW: GERD after bariatric surgery is an ongoing concern for bariatric surgeons and their patients. This paper reviews the association of persistent or de novo GERD after multiple types of bariatric surgery, and focuses on the work up and management of GERD after SG. RECENT FINDINGS: Two recent large, multicenter randomized clinical trials have shown stronger associations between SG and GERD compared to RYGB. A large group of internationally recognized bariatric surgeons collaborated on 72 consensus statements to help guide the bariatric community on the subject of redo surgeries after SG, including as it pertains to GERD. We present an algorithm that consolidates the best-practices recommendations of the work-up and management of GERD after sleeve gastrectomy, and mention areas of persistent controversy where future research is warranted.

Endoscopic Non-ablative Radiofrequency Treatment (Stretta) for Gastroesophageal Reflux Disease (GERD).

PURPOSE OF REVIEW: Gastroesophageal reflux disease (GERD) is very common in the general population and poses a large societal socio-economic burden. In this article, we review the evidence supporting non-ablative radiofrequency treatment (Stretta) for the endoscopic management of GERD and we compare it to pharmacologic and other minimally invasive and surgical interventions. RECENT FINDINGS: Proton pump inhibitors (PPI) are a key therapy for GERD. For patients without associated significant sliding hiatal hernia, who have inadequate relief of their reflux symptoms, Stretta and other endoscopic therapies, such as transoral fundoplication (TIF), may improve symptoms and GERD-related quality of life. Unfortunately, there are no recent large randomized controlled trials, and most of the evidence is based on meta-analyses and small scale, prospective and retrospective single center efforts. Comparisons of Stretta efficacy to other anti-reflux endoscopic modalities and anti-reflux surgery (ARS) are also presented. There are several endoscopic and minimally invasive modalities to manage PPI-refractory GERD acting through various mechanisms that have been found effective in managing GERD symptoms and quality of life. Among them, Stretta has the longest track record of efficacy and safety. Larger-scale and longer-term comparative efficacy trials in selected populations of patients with acid reflux with and without hiatal hernia will be needed.

Modifiable risk factors mediate the effect of gastroesophageal reflux disease on stroke and subtypes: A Mendelian randomization study.

OBJECTIVES: Previous observational studies have suggested that gastroesophageal reflux disease (GERD) increases the risk of stroke, but the specific underlying mechanisms are unclear. We investigated the causal associations of GERD with stroke and its subtypes using Mendelian randomization (MR), and evaluated the potential mediating effects of modifiable stroke risk factors in the causal pathway. METHODS: Genetic instrumental variables for GERD were extracted from the latest genome-wide association study (GWAS) summary level data. We initially performed two-sample MR to examine the association of GERD with stroke and its subtypes, including ischemic stroke, intracranial hemorrhage, and the major subtypes of ischemic stroke. Two-step MR was further employed to investigate the mediating effect of 15 risk factors in the causal pathway. RESULTS: We found significant causal associations of genetically predicted GERD with increased risk of stroke (OR: 1.22 95% CI: 1.126-1.322), ischemic stroke (OR: 1.19 95% CI: 1.098-1.299), and large-artery stroke (OR: 1.49 95% CI: 1.214-1.836). Replication and sensitivity analyses yielded consistent effect directions and similar estimates. Further mediation analyses indicated that hypertension (HTN), systolic blood pressure (SBP), and type 2 diabetes (T2D) mediated 36.0%, 9.0%, and 15.8% of the effect of GERD on stroke; 42.9%, 10.8%, and 21.4% for ischemic stroke, and 23.3%; 7.9%, and 18.7% for large-artery stroke, respectively. CONCLUSIONS: This study supports that GERD increases susceptibility to stroke, ischemic stroke, and large-artery stroke, and is partially mediated by HTN, SBP, and T2D.
