Neutrophils, eosinophils, and intraepithelial lymphocytes in the squamous esophagus in subjects with and without gastroesophageal reflux symptoms. Hum Pathol 2021; 115:112-122. [PMID: 34181982 DOI: 10.1016/j.humpath.2021.06.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 06/17/2021] [Accepted: 06/18/2021] [Indexed: 02/07/2023]
Abstract
Whilst intraepithelial lymphocytes (IELs) are considered normal within the distal esophageal mucosa, they have an increasingly recognised role in the pathogenesis of reflux esophagitis, and IEL quantification establishes the diagnosis of lymphocytic esophagitis. Knowledge regarding the upper limit of a normal IEL count in health is lacking. We studied 117 non-healthcare seeking adult volunteers from a random community sample (the Kalixanda study) with esophageal biopsies 2 cm above the gastroesophageal junction. Subjects were divided into four groups based on the presence or absence of gastro-esophageal reflux symptoms and/or esophagitis on endoscopy. Asymptomatic subjects with no endoscopic esophagitis were selected as controls, and the cell counts in this group were used to define the upper limit of normal of IELs, eosinophils and neutrophils. The entire sample was used to identify independent predictors of increased cellular counts by logistic regression analysis. None of the healthy controls had an IEL count of more than three per five high power fields (HPF), and therefore this was considered as the upper limit of normal; no controls had eosinophils or neutrophils in esophageal biopsies. Independent predictors of an elevated IEL count were spongiosis on histology (OR 11.17, 95% CI 3.32-37.58, P < 0.01) and current smoking (OR 4.84, 95% CI 1.13-2.71, P = 0.03). A receiver operating characteristics analysis concluded that a threshold of 3 IELs/5HPFs performs best in predicting reflux symptoms when a normal esophageal mucosa is visualized on endoscopy (sensitivity = 100.0%, specificity = 35.2%). The healthy esophageal mucosa does not contain more than three IELs per five HPF in the distal esophagus.

Abstract
OBJECTIVE Although lifestyle-related factors have separately been examined in relation to functional gastrointestinal disorders (FGIDs), there is no epidemiological data on the combined association of lifestyle factors with these conditions. We aimed to examine how combinations of several lifestyle factors were associated with functional dyspepsia (FD), its symptoms, and gastroesophageal reflux disease (GERD) in a large group of Iranian adults. DESIGN, SETTING, AND SUBJECTS In a cross-sectional study on 3,363 Iranian adults, we calculated the "healthy lifestyle score" for each participant by summing up the binary score given for 5 lifestyle factors, including dietary habits, dietary intakes, psychological distress, smoking, and physical activity. A dish-based 106-item semi-quantitative validated food frequency questionnaire, General Practice Physical Activity Questionnaire, General Health Questionnaire, and other pre-tested questionnaires were used to assess the components of healthy lifestyle score. To assess FGIDs, a validated Persian version of ROME III questionnaire was used. RESULTS After adjustment for potential confounders, we found that individuals with the highest score of healthy lifestyle had 79 and 74% lower odds of FD (OR: 0.21; 95% CI: 0.05-0.92) and GERD (OR: 0.26; 95% CI: 0.09-0.69), respectively, compared with those with the lowest score. They were also less likely to have early satiation (OR: 0.28; 95% CI: 0.11-0.73), postprandial fullness (OR: 0.22; 95% CI: 0.09-0.50), and epigastric pain (OR: 0.44; 95% CI: 0.21-0.92). In addition to the combined healthy lifestyle score, low levels of psychological distress, a healthy diet, healthy dietary habits, and nonsmoking were separately and protectively associated with FGIDs. CONCLUSION We found that adherence to a healthy lifestyle was associated with lower odds of GERD, FD, and its symptoms in this group of Iranian adults, in a dose-response manner. Individual lifestyle-related factors were also associated with these conditions.

Abstract
Several lifestyle and dietary factors are commonly cited as risk factors for gastro-oesophageal reflux disease (GORD) and modification of these factors has been advocated as first-line measures for the management of GORD. We performed a systematic review of the literature from 2005 to the present relating to the effect of these factors and their modification on GORD symptoms, physiological parameters of reflux as well as endoscopic appearances. Conflicting results existed for the association between smoking, alcohol and various dietary factors in the development of GORD. These equivocal findings are partly due to methodology problems. There is recent good evidence that weight reduction and smoking cessation are beneficial in reducing GORD symptoms. Clinical and physiological studies also suggest that some physical measures as well as modification of meal size and timing can also be beneficial. However, there is limited evidence for the role of avoiding alcohol and certain dietary ingredients including carbonated drinks, caffeine, fat, spicy foods, chocolate and mint.

Abstract
Laryngopharyngeal reflux is defined as the reflux of gastric content into larynx and pharynx. A large number of data suggest the growing prevalence of laryngopharyngeal symptoms in patients with gastroesophageal reflux disease. However, laryngopharyngeal reflux is a multifactorial syndrome and gastroesophageal reflux disease is not the only cause involved in its pathogenesis. Current critical issues in diagnosing laryngopharyngeal reflux are many nonspecific laryngeal symptoms and signs, and poor sensitivity and specificity of all currently available diagnostic tests. Although it is a pragmatic clinical strategy to start with empiric trials of proton pump inhibitors, many patients with suspected laryngopharyngeal reflux have persistent symptoms despite maximal acid suppression therapy. Overall, there are scant conflicting results to assess the effect of reflux treatments (including dietary and lifestyle modification, medical treatment, antireflux surgery) on laryngopharyngeal reflux. The present review is aimed at critically discussing the current treatment options in patients with laryngopharyngeal reflux, and provides a perspective on the development of new therapies.

Abstract
Gastroesophageal reflux disease is increasingly associated with ear, nose, and throat symptoms, including laryngitis. Many patients are unaware of the gastroesophageal etiology of their symptoms. A variety of criteria are used to diagnose this condition, including laryngoscopy, esophagogastroduodenoscopy, and the use of ambulatory pH and impedance monitoring. However, no test serves as the gold standard for the diagnosis given their lack of sensitivity and specificity for reflux disease. Numerous trials have assessed the role of proton pump inhibitor therapy in patients with laryngopharyngeal reflux and most have revealed no benefit to acid suppression over placebo. Despite many uncertainties there has been some progress regarding the role of acid-suppressive therapy as well as other agents in this unique group of patients. In this review we explore therapeutic options and their rationale for patients with laryngeal signs and symptoms.

Abstract
BACKGROUND/AIMS Recent studies suggest that the prevalence of gastroesophageal reflux disease (GERD) is increasing in Korea. However, studies on risk factors for GERD have yielded inconsistent results. The aims of this study were to compare clinical features between symptomatic syndromes without esophageal injury (=non-erosive disease [NED]) and syndromes with esophageal injury (=erosive disease [ED]), and to determine risk factors associated ED. METHODS A total of 450 subjects who visited gastroenterology clinics of six training hospitals in Daegu from March 2008 to April 2010 were consecutively enrolled. The subjects were asked to complete a questionnaire which inquired about gastroesophageal reflux symptoms. The questionnaire also included questions about smoking, alcohol drinking, consumption of coffee, use of drugs, exercise, and other medical history. The subjects were subdivided into NED and ED groups. RESULTS The proportion of subjects in each NED and ED group was 172 (38.2%) and 278 (61.8%). Male gender, smoking, alcohol drinking, consumption of coffee, large waist circumference, infrequent medication of antacids, aspirin and NSAIDs, infrequent and mild GERD symptoms were all significantly associated with ED on univariate analysis. Age, hiatal hernia, diabetes mellitus, body mass index, change in weight during 1 year, and number of typical GERD symptoms were not independent risk factors for ED. However, the association between ED and alcohol drinking, infrequent medication of antacids, mild typical GERD symptoms remained as strong risk factors after adjustments on multivariate logistic analysis. CONCLUSIONS Independent risk factors associated with ED were alcohol drinking, infrequent medication of antacids and mild typical GERD symptoms.

Abstract
While lifestyle modifications are currently used as first-line treatment for subjects with gastroesophageal reflux disease (GERD), the pathogenetic role of lifestyle factors and consequently, the efficacy of lifestyle measures is controversial. Our aim was to systematically review the pathogenetic link between overweight/obesity, dietary habits, physical activity and GERD, and the beneficial effect of specific recommended changes, by means of the available literature from the 1999 to the present. Obesity, in particular, abdominal obesity, plays a key role in determining GERD symptoms and complications through mechanical and metabolic effects. Controlled weight loss (by diet or surgery) is effective in improving GERD symptoms. No definitive data exist regarding the role of diet and, in particular, of specific foods or drinks, in influencing GERD clinical manifestations. Moderate physical activity seems to be beneficial for GERD, while vigorous activity may be dangerous in predisposed individuals. In conclusion, being obese/overweight and GERD-specific symptoms and endoscopic features are related, and weight loss significantly improves GERD clinical-endoscopic manifestations. The role of dietary behavior, mainly in terms of specific dietary components, remains controversial. Mild routine physical activity in association with diet modifications, i.e. a diet rich in fiber and low in fat, is advisable in preventing reflux symptoms.

Abstract
Gastroesophageal reflux disease is a chronic condition affecting 44% of the American population at least once a month, with daily occurrences affecting about 7% of the population. It is the most common gastrointestinal-related diagnosis given by physicians during clinic visits in the United States. Treatment of this disease is a step-wise approach that includes diet and lifestyle interventions as well as medications titrated based on symptom severity. This article reviews dietary and lifestyle factors that contribute to the physiology and symptoms of gastroesophageal reflux disease and modification of these factors as an adjunctive therapy.

Abstract
BACKGROUND & AIMS Lifestyle and genetic factors dominate the etiology of gastroesophageal reflux disease. We investigated associations between lifestyle factors and gastroesophageal reflux (GER) symptoms, with and without controlling for genetic predisposition. METHODS In 1967 and 1973, questionnaires including lifestyle exposures were mailed to twins in the Swedish Twin Registry, and data on GER symptoms were collected by telephone interview during 1998-2002. Two analytic methods were used: external control analysis (4083 twins with GER symptoms and 21,383 controls) and monozygotic co-twin control analysis (869 monozygotic twin pairs discordant for GER symptoms). RESULTS In the external control analysis, leanness (body mass index [BMI] <20), upper normal weight (BMI 22.5-24.9), overweight (BMI 25-29.9), and obese (BMI > or =30) conferred -19%, 25%, 46%, and 59% increased risk of frequent GER symptoms compared with normal weight (BMI 20-22.4), respectively, among women, whereas no such associations were evident among men. When adjusted for genetic and nongenetic familial factors, these estimates were -28%, 44%, 187%, and 277%, respectively, among men. Frequent smoking rendered a 37% increased risk of frequent GER symptoms among women and 53% among men compared with nonsmokers. Physical activity at work was dose dependently associated with increased risk of frequent GER symptoms, and recreational physical activity decreased this risk. CONCLUSIONS BMI, tobacco smoking, and physical activity at work appear to be risk factors for frequent GER symptoms, whereas recreational physical activity appears to be beneficial. Association between BMI and frequent GER symptoms among men seems to be attenuated by genetic factors.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most prevalent diseases in the industrialized countries. Approximately 15-25% of adults suffer from reflux symptoms, characterized mainly by heartburn and/or regurgitation. Currently, antisecretory medication with proton pump inhibitors (PPI) or antireflux surgery are the established options for GERD-treatment. PPI are the therapeutic gold standard in acute, long-term or on-demand therapy of GERD. Since PPI do not restore the antireflux barrier but merely suppress acid secretion a life-long tablet adherence is required in most cases. In view of limitations of PPI and the potential risks of laparoscopic surgery, several endoscopic antireflux techniques were developed and may evolve as a valuable third option. However, so far objective long-term data are lacking for choosing the appropriate patient who will benefit most from endoluminal antireflux therapy.

Abstract
Gastroesophageal reflux (GER), defined as passage of gastric contents into the esophagus, and GER disease (GERD), defined as symptoms or complications of GER, are common pediatric problems encountered by both primary and specialty medical providers. Clinical manifestations of GERD in children include vomiting, poor weight gain, dysphagia, abdominal or substernal pain, esophagitis and respiratory disorders. The GER Guideline Committee of the North American Society for Pediatric Gastroenterology and Nutrition has formulated a clinical practice guideline for the management of pediatric GER. The GER Guideline Committee, consisting of a primary care pediatrician, two clinical epidemiologists (who also practice primary care pediatrics) and five pediatric gastroenterologists, based its recommendations on an integration of a comprehensive and systematic review of the medical literature combined with expert opinion. Consensus was achieved through Nominal Group Technique, a structured quantitative method. The Committee examined the value of diagnostic tests and treatment modalities commonly used for the management of GERD, and how those interventions can be applied to clinical situations in the infant and older child. The guideline provides recommendations for management by the primary care provider, including evaluation, initial treatment, follow-up management and indications for consultation by a specialist. The guideline also provides recommendations for management by the pediatric gastroenterologist. This document represents the official recommendations of the North American Society for Pediatric Gastroenterology and Nutrition on the evaluation and treatment of gastroesophageal reflux in infants and children. The American Academy of Pediatrics has also endorsed these recommendations. The recommendations are summarized in a synopsis within the article. This review and recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the management of all patients with this problem.

Abstract
Barrett esophagus is a metaplastic condition that affects the lower esophagus and is a complication of gastroesophageal reflux disease (GERD). Under normal circumstances, the reflux of gastric contents into the esophagus is prevented by a complex barrier at the esophagogastric junction. Dysfunction of the lower esophageal sphincter and the presence of a hiatal hernia lead to failure of this barrier. Esophageal mucosal damage results from the chronic exposure of the esophageal mucosa to gastroduodenal contents and the lack of an effective mucosal defense. This article is an overview of the dysfunction of the esophagogastric junction that leads to GERD. The role of the contents of the reflux and that of Helicobacter pylori infection in the pathogenesis of Barrett esophagus are also summarized.

Abstract
Gastroesophageal reflux disease (GERD) and the complications associated with it are very common in the Western world. There has been speculation for many years that certain dietary and lifestyle factors may play a role in the pathogenesis or course of GERD. However, a wide-ranging review of the available data reveals conflicting findings regarding the impact of most of these factors. In addition, the majority of the studies concerned have been based on small numbers of patients, and in most cases these studies do not meet the criteria for evidence-based medicine. Consequently, any advice given on modifying diet and/or lifestyle in the management of GERD represents a form of empirical therapy. A general consensus on the control of GERD through alterations in diet and lifestyle factors could hardly be based on the results of clinical or outcome studies. In practice, however, the treatment of GERD is oriented toward the individual patient's symptoms, and includes offering reasonable advice on how to adapt to personal dietary intolerance and lifestyle factors.

Abstract
Tobacco smoke has a myriad of acute and chronic effects on the upper airway. These problems can range from aggravating inflammatory reactions to life threatening malignancies. Cessation of smoking is the key to successful resolution of many upper airway complaints. An increased awareness of these disease processes can improve early diagnosis and appropriate treatment. A better awareness of these processes may facilitate physicians in counseling patients about smoking.
