Impact of metabolic unhealthiness and its changes on the risk of erosive esophagitis: a cohort study.

BACKGROUND AND AIM: We aimed to compare the risk of erosive esophagitis (EE) among individuals with different phenotypes based on metabolic health status and obesity and investigate the role of changes in metabolic health in EE risk. METHODS: A cohort of 258 892 asymptomatic adults without EE at baseline who underwent ollow-up esophagogastroduodenoscopy (EGD) were categorized into the following four groups according to metabolic health and obesity status: (i) metabolically healthy (MH) non-obese; (ii) metabolically unhealthy (MU) non-obese; (iii) MH obese; and (iv) MU obese. EE was defined as the presence of grade A or higher mucosal breaks on EGD. RESULTS: During a median follow-up of 4.5 years, the incidence rates of EE were 0.6/103 person-years (PY), 1.7/103 PY, 1.7/103 PY, and 3.1/103 PY in the MH non-obese, MU non-obese, MH obese, and MU obese groups, respectively. The multivariable-adjusted hazard ratio (HR) (95% confidence intervals [CI]) for developing EE comparing the MH obese, MU non-obese, and MU obese groups with the MH non-obese group were 1.49 (1.29-1.71), 1.56 (1.25-1.94), and 2.18 (1.90-2.49), respectively. The multivariable-adjusted HR (95% CI) comparing the progression of MH to MU, regression of MU to MH, and persistent MU with the persistent MH group were 1.39 (1.10-1.76), 1.39 (1.09-1.77), and 1.86 (1.56-2.21), respectively. The increased risk of EE among the persistent MU group was consistently observed in individuals without obesity or abdominal obesity. CONCLUSION: Metabolic unhealthiness and obesity were independent risk factors for the development of EE, suggesting that maintaining both normal weight and metabolic health may help reduce the risk of EE.

Association of metabolic dysfunction-associated steatotic liver disease with erosive esophagitis development: a longitudinal observational study.

BACKGROUND AND AIM: Although erosive esophagitis (EE) is associated with fatty liver and metabolic dysregulation, the association between EE and metabolic dysfunction-associated steatotic liver disease (MASLD) remains unclear. Thus, this study aimed to investigate the longitudinal association between MASLD and EE. METHODS: We included 1578 patients without EE at baseline who underwent more than two health checkups over 2 years. Generalized estimation equations were used to analyze associations between MASLD and EE according to repeated measures at baseline and most recent stages. RESULTS: EE development rates in men and women were 14.5% and 7.2%, respectively. After adjusting for lifestyle habits, the odds ratios of MASLD for EE development in men and women were 1.907 (95% confidence interval [CI]: 1.289-2.832, P < 0.005) and 1.483 (95% CI: 0.783-2.811, P = 0.227), respectively. In the subgroup analysis, after adjusting for lifestyle habits, among men and women aged ≥50 years with more than three MASLD components, the odds ratios for EE development were 2.408 (95% CI: 1.505-3.855, P < 0.001) and 2.148 (95% CI: 1.093-4.221, P < 0.05), respectively. After adjusting for various factors, the significant risk factors for EE development were different between men and women. CONCLUSION: The influence of MASLD and other factors on EE development differed by sex and age. Particularly, patients aged ≥50 years with MASLD and with an increased number of MASLD components should be considered at increased risk for EE.

Prevalence, Predictive Factors, and Clinical Manifestations of Fungal Esophagitis in Children.

OBJECTIVES: Fungal esophagitis (FE) is the most common cause of esophageal infection and its prevalence in immunocompetent adults is rising. However, there is minimal data on FE in children without human immunodeficiency virus. Therefore, the objective of this study was to determine the prevalence, symptoms, endoscopic appearances, and predictive factors of FE in children, regardless of immune status. METHODS: A 2010-2020 retrospective case-control study was conducted on 1823 children presenting to Sydney Children's Hospital for elective endoscopy with esophageal biopsy. Histopathology reports were reviewed to identify FE cases and determine prevalence rates. Thirty-two patients with FE were age- and sex-matched (1:2) to 64 controls. Significant symptoms and risk factors of FE were identified via univariate and multivariate logistic regression analysis. RESULTS: The prevalence of FE in children was 1.76%. Common symptoms included dysphagia (25%), heartburn (25%), poor oral intake (21.9%), vomiting (18.8%), cough (15.6%), nausea (12.5%), and weight loss (9.4%). No significant differences in symptoms were found between cases and controls. On endoscopy, although white plaques were associated with FE ( P < 0.001), visually normal findings were reported in 28.1% of cases. Topical swallowed corticosteroids were a significant independent risk factor for FE (adjusted odds ratio = 10.740, 95% confidence interval: 1.213-95.101, P = 0.033). CONCLUSIONS: The prevalence of FE in this pediatric cohort reflects rates among immunocompetent adults. Given that many of these children presented with a wide range of gastrointestinal symptoms, esophageal biopsy is required to accurately diagnose FE. Pediatricians should consider the risk of FE when prescribing topical swallowed corticosteroids.

Model development of dose and volume predictors for esophagitis induced during chemoradiotherapy for lung cancer as a step towards radiobiological treatment planning.

BACKGROUND: Currently, radiation therapy treatment planning system intends biological optimization that relies heavily upon plan metrics from tumor control probability (TCP) and normal tissue complication probability (NTCP) modeling. Implementation and expansion of TCP and NTCP models with alternative data is an important step towards reliable radiobiological treatment planning. In this retrospective single institution study, the treatment charts of 139 lung cancer patients treated with chemo-radiotherapy were reviewed and correlated dosimetric predictors with the incidence of esophagitis and established NTCP model of esophagitis grade 1 and 2 for lung cancer patients. METHODS: Esophagus is an organ at risk (OAR) in lung cancer radiotherapy (RT). Esophagitis is a common toxicity induced by RT. In this study, dose volume parameters Vx (Vx: percentage esophageal volume receiving ≥ x Gy) and mean esophagus dose (MED) as quantitative dose-volume metrics, the esophagitis grade 1 and 2 as endpoints, were reviewed and derived from the treatment planning system and the electronic medical record system. Statistical analysis of binary logistic regression and probit were performed to have correlated the probability of grade 1 and 2 esophagitis to MED and Vx. IBM SPSS software version 24 at 5% significant level (α = 0.05) was used in the statistical analysis. RESULTS: The probabilities of incidence of grade 1 and 2 esophagitis proportionally increased with increasing the values of Vx and MED. V20, V30, V40, V50 and MED are statistically significant good dosimetric predictors of esophagitis grade 1. 50% incidence probability (TD50) of MED for grade 1 and 2 esophagitis were determined. Lyman Kutcher Burman model parameters, such as, n, m and TD50, were fitted and compared with other published findings. Furthermore, the sigmoid shaped dose responding curve between probability of esophagitis grade 1 and MED were generated respecting to races, gender, age and smoking status. CONCLUSIONS: V20, V30, V40 and V50 were added onto Quantitative Analysis of Normal Tissue Effects in the clinic, or QUANTEC group's dose constrains of V35, V50, V70 and MED. Our findings may be useful as both validation of 3-Dimensional planning era models and also additional clinical guidelines in treatment planning and plan evaluation using radiobiology optimization.

[Analysis of risk factors of radiation-induced toxicity in limited-stage small cell lung cancer treated with hypofractionated intensity-modulated radiotherapy].

Objective: To compare the incidence of radiation-related toxicities between conventional and hypofractionated intensity-modulated radiation therapy (IMRT) for limited-stage small cell lung cancer (SCLC), and to explore the risk factors of hypofractionated radiotherapy-induced toxicities. Methods: Data were retrospectively collected from consecutive limited-stage SCLC patients treated with definitive concurrent chemoradiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from March 2016 to April 2022. The enrolled patients were divided into two groups according to radiation fractionated regimens. Common Terminology Criteria for Adverse Events (CTCAE, version 5.0) was used to evaluate the grade of radiation esophagus injuries and lung injuries. Logistic regression analyses were used to identify factors associated with radiation-related toxicities in the hypofractionated radiotherapy group. Results: Among 211 enrolled patients, 108 cases underwent conventional IMRT and 103 patients received hypofractionated IMRT. The cumulative incidences of acute esophagitis grade ≥2 [38.9% (42/108) vs 35.0% (36/103), P=0.895] and grade ≥ 3 [1.9% (2/108) vs 5.8% (6/103), P=0.132] were similar between conventional and hypofractionated IMRT group. Late esophagus injuries grade ≥2 occurred in one patient in either group. No differences in the cumulative incidence of acute pneumonitis grade ≥2[12.0% (13/108) vs 5.8% (6/103), P=0.172] and late lung injuries grade ≥2[5.6% (6/108) vs 10.7% (11/103), P=0.277] were observed. There was no grade ≥3 lung injuries occurred in either group. Using multiple regression analysis, mean esophageal dose ≥13 Gy (OR=3.33, 95% CI: 1.23-9.01, P=0.018) and the overlapping volume between planning target volume (PTV) and esophageal ≥8 cm(3)(OR=3.99, 95% CI: 1.24-12.79, P=0.020) were identified as the independent risk factors associated with acute esophagitis grade ≥2 in the hypofractionated radiotherapy group. Acute pneumonitis grade ≥2 was correlated with presence of chronic obstructive pulmonary disease (COPD, P=0.025). Late lung injuries grade ≥2 was correlated with tumor location(P=0.036). Conclusions: Hypofractionated IMRT are tolerated with manageable toxicities for limited-stage SCLC patients treated with IMRT. Mean esophageal dose and the overlapping volume between PTV and esophageal are independently predictive factors of acute esophagitis grade ≥2, and COPD and tumor location are valuable factors of lung injuries for limited-stage SCLC patients receiving hyofractionated radiotherapy. Prospective studies are needed to confirm these results.

Gastroesophageal Reflux Disease Outcomes After Vertical Sleeve Gastrectomy and Gastric Bypass.

OBJECTIVE: The objective of this study is to assess whether vertical sleeve gastrectomy (VSG) increases the incidence of gastroesophageal reflux disease (GERD), esophagitis and Barrett esophagus (BE) relative to patients undergoing Roux-en-Y gastric bypass (RYGB) in patients with and without preoperative GERD. SUMMARY OF BACKGROUND DATA: Concerns for potentiation of GERD, supported by multiple high-quality retrospective studies, have hindered greater adoption of the VSG. METHODS: From the OptumLabs Data Warehouse, VSG and RYGB patients with ≥2 years enrollment were identified and matched by follow-up time. GERD [reflux esophagitis, prescription for acid reducing medication (Rx) and/or diagnosis of BE], upper endoscopy (UE), and re-admissions were evaluated beyond 90 days. RESULTS: A total of 8362 patients undergoing VSG were matched 1:1 to patients undergoing RYGB, on the basis of post-operative follow-up interval. Age, sex, and follow-up time were similar between the 2 groups (P > 0.05). Among all patients, postoperative GERD was more frequently observed in VSG patients relative to RYGB patients (60.2% vs 55.6%, respectively; P < 0.001), whereas BE was more prevalent in RYGB patients (0.7% vs 1.1%; P = 0.007). Postoperatively, de novo esophageal reflux symptomatology was more common in VSG patients (39.3% vs 35.3%; P < 0.001), although there was no difference in development of the histologic diagnoses reflux esophagitis and BE. Furthermore, postoperative re-admission was higher in the RYGB cohort (38.9% vs 28.9%; P < 0.001). CONCLUSIONS: Compared to RYGB, VSG may not have inferior long-term GERD outcomes, while also leading to fewer re-hospitalizations. These data challenge the prevailing opinion that patients with GERD should undergo RYGB instead of VSG.

Incomplete Response of Gastroesophageal Reflux Symptoms Poorly Predicts Erosive Esophagitis or Barrett's Esophagus.

BACKGROUND & AIMS: Many patients with symptoms of gastroesophageal reflux disease (GERD) not responding to a proton pump inhibitor (PPI) undergo an upper endoscopy. We hypothesized that an incomplete response to a PPI is not associated with findings of esophageal pathology on endoscopy, and that psychological distress is associated inversely with pathology. METHODS: We enrolled consecutive individuals aged 40 to 79 years with prior heartburn or regurgitation. Logistic regression was used to estimate the effects of incomplete response of GERD symptoms and psychological distress on the odds of finding erosive esophagitis or Barrett's esophagus. RESULTS: A total of 625 patients completed the study. A total of 254 (66.8% of those taking PPI) had GERD symptoms incompletely responsive to a PPI and 352 (56.3%) had severe somatization. An incomplete response to a PPI was associated with psychological distress (P < .001). Erosive esophagitis was found in 148 subjects (23.7%) and Barrett's esophagus in 58 (9.3%). Overall, an incomplete response to a PPI was not found to be associated with these pathologies (odds ratio, 1.17; 95% CI, 0.720-1.91). In contrast, greater psychological distress was associated inversely with erosive esophagitis or Barrett's esophagus (in particular, highest vs lowest tertile somatization: odds ratio, 0.590; 95% CI, 0.365-0.952). CONCLUSIONS: Patients undergoing upper endoscopy frequently have GERD symptoms incompletely responding to a PPI and a high burden of somatization. However, an incomplete response of GERD symptoms is a poor predictor for endoscopic pathology, and should not be relied upon for selecting patients for screening for Barrett's esophagus. Patients with high psychological distress are less likely to have esophageal pathology.

Effects of glutamine for prevention of radiation-induced esophagitis: a double-blind placebo-controlled trial.

Purpose Acute radiation-induced esophagitis (ARIE) leads to treatment delays, decreased quality of life (QOL), and secondary adverse events such as weight loss. Grade 3 ARIE occurs in 15%-30% of patients undergoing radiotherapy to the esophagus, leading to disruption or discontinuation of treatment. The purpose of this study was to assess the effects of glutamine, a common nutritional supplement, on ARIE in patients with thoracic malignancies. Patients and methods This double-blind, placebo-controlled trial enrolled patients with advanced thoracic malignancies receiving concurrent chemotherapy/radiotherapy or radiotherapy alone, with radiation doses to the esophagus ≥45 Gy. Patients were randomized (1:1) to receive 4 g of glutamine or glycine placebo twice daily. The primary objective was to determine whether glutamine decreases the severity of ARIE in these patients. Secondary objectives included assessment of the effects of glutamine on other measures of ARIE, weight, symptom burden measure assessed by the MD Anderson Symptom Inventory (MDASI-HN) questionnaire and the toxicity profile of glutamine. Results At the time of interim analysis, 53 patients were enrolled: 27 in the glutamine arm and 26 in the placebo arm. There was no difference in the incidence of esophagitis in the first 6 weeks of radiotherapy between the glutamine and placebo arms (74% versus 68%; P = 1.00). There were no significant differences between the two arms for time to onset of esophagitis. The duration of ARIE was shorter (6.3 versus 7.1 weeks; P = 0.54) and median weight loss was lower (0.9 kg versus 2.8 kg; p = 0.83) in the glutamine arm versus the placebo arm. The groups differ significantly in core symptom severity (2.1 vs 1.5, p < .03) but not in head and neck specific symptom severity (1.2 vs 1.1, p < .60) nor in symptom interference (2.1 vs 1.7, p < .22). There was no grade 3 or higher adverse event at least possibly related to glutamine. The study was terminated for futility following interim analysis. Conclusion Oral glutamine was not associated with significant improvement in severity of ARIE, weight loss, head and neck specific symptoms or symptom interference compared with placebo in patients with advanced thoracic malignancies receiving radiotherapy to the esophagus.Clinical trial information.

A novel nomogram containing acute radiation esophagitis predicting radiation pneumonitis in thoracic cancer receiving radiotherapy.

BACKGROUND: Radiation-induced pneumonitis (RP) is a non-negligible and sometimes life-threatening complication among patients with thoracic radiation. We initially aimed to ascertain the predictive value of acute radiation-induced esophagitis (SARE, grade ≥ 2) to symptomatic RP (SRP, grade ≥ 2) among thoracic cancer patients receiving radiotherapy. Based on that, we established a novel nomogram model to provide individualized risk assessment for SRP. METHODS: Thoracic cancer patients who were treated with thoracic radiation from Jan 2018 to Jan 2019 in Shandong Cancer Hospital and Institute were enrolled prospectively. All patients were followed up during and after radiotherapy (RT) to observe the development of esophagitis as well as pneumonitis. Variables were analyzed by univariate and multivariate analysis using the logistic regression model, and a nomogram model was established to predict SRP by "R" version 3.6.0. RESULTS: A total of 123 patients were enrolled (64 esophageal cancer, 57 lung cancer and 2 mediastinal cancer) in this study prospectively. RP grades of 0, 1, 2, 3, 4 and 5 occurred in 29, 57, 31, 0, 3 and 3 patients, respectively. SRP appeared in 37 patients (30.1%). In univariate analysis, SARE was shown to be a significant predictive factor for SRP (P < 0.001), with the sensitivity 91.9% and the negative predictive value 93.5%. The incidence of SRP in different grades of ARE were as follows: Grade 0-1: 6.5%; Grade 2: 36.9%; Grade 3: 80.0%; Grade 4: 100%. Besides that, the dosimetric factors considering total lung mean dose, total lung V5, V20, ipsilateral lung mean dose, ipsilateral lung V5, and mean esophagus dose were correlated with SRP (all P < 0.05) by univariate analysis. The incidence of SRP was significantly higher in patients whose symptoms of RP appeared early. SARE, mean esophagus dose and ipsilateral mean lung dose were still significant in multivariate analysis, and they were included to build a predictive nomogram model for SRP. CONCLUSIONS: As an early index that can reflect the tissue's radiosensitivity visually, SARE can be used as a predictor for SRP in patients receiving thoracic radiation. And the nomogram containing SARE may be fully applied in future's clinical work.

Primary gross tumor volume is prognostic and suggests treatment in upper esophageal cancer.

BACKGROUND: To aid clinicians strategizing treatment for upper esophageal squamous cell carcinoma (ESCC), this retrospective study investigated associations between primary gross tumor volume (GTVp) and prognosis in patients given surgical resection, radiotherapy, or both resection and radiotherapy. METHODS: The population comprised 568 patients with upper ESCC given definitive treatment, including 238, 216, and 114 who underwent surgery, radiotherapy, or combined radiotherapy and surgery. GTVp as a continuous variable was entered into the multivariate Cox model using penalized splines (P-splines) to determine the optimal cutoff value. Propensity score matching (PSM) was used to adjust imbalanced characteristics among the treatment groups. RESULTS: P-spline regression revealed a dependence of patient outcomes on GTVp, with 30 cm3 being an optimal cut-off for differences in overall and progression-free survival (OS, PFS). GTVp ≥30 cm3 was a negative independent prognostic factor for OS and PFS. PSM analyses confirmed the prognostic value of GTVp. For GTVp < 30 cm3, no significant survival differences were observed among the 3 treatments. For GTVp ≥30 cm3, the worst 5-year OS rate was experienced by those given surgery. The 5-year PFS rate of patients given combined radiotherapy and surgery was significantly better than that of patients given radiotherapy. The surgical complications of patients given the combined treatment were comparable to those who received surgery, but radiation side effects were significantly lower. CONCLUSION: GTVp is prognostic for OS and PFS in upper ESCC. For patients with GTVp ≥30 cm3, radiotherapy plus surgery was more effective than either treatment alone.

Risk factors for esophageal squamous cell carcinoma and its histological precursor lesions in China: a multicenter cross-sectional study.

BACKGROUND: Despite research efforts, the causative factors that contribute to esophageal squamous cell carcinoma (ESCC) in high-risk areas have not yet been understood. In this study, we, therefore, aimed to describe the risk factors associated with ESCC and its precursor lesions. METHODS: We performed an endoscopic examination of 44,857 individuals aged 40-69 years from five high incidence regions of China in 2017-2018. Participants were classified as 4 groups of normal control, esophagitis, low-grade intraepithelial neoplasia (LGIN) and high-grade intraepithelial neoplasia/esophageal squamous cell carcinoma (HGIN/ESCC) using an unconditional logistic regression determine risk factors. RESULTS: We identified 4890 esophagitis, 1874 LGIN and 437 HGIN/ESCC cases. Crude odds ratios (ORs) and adjusted odds ratios were calculated using unconditional logistic regression. Drinking well and surface water, salty diet, and positive family history of cancer were the common risk factors for esophagitis, LGIN and HGIN/ESCC. History of chronic hepatitis/cirrhosis was the greatest risk factor of esophagitis (adjusted OR 2.96, 95%CI 2.52-3.47) and HGIN/ESCC (adjusted OR 1.91, 95%CI 1.03-3.22). Pesticide exposure (adjusted OR 1.20, 95%CI 1.05-1.37) was essential risk factor of LGIN. CONCLUSIONS: Among individuals aged 40-69 years in high incidence regions of upper gastrointestinal cancer, the results provided important epidemiological evidence for the prevention of different precancerous lesions of ESCC.

Extra-esophageal symptoms in individuals with and without erosive esophagitis: a case-control study in Albania.

INTRODUCTION: Erosive reflux esophagitis caused a large clinical spectrum of symptoms. Our aim was to assess the prevalence of extra-esophageal symptoms in individuals with and those without erosive esophagitis in Albania. METHODS: A case-control study was conducted at the Regional Hospital of Durres, the second main district in Albania, a transitional country in South Eastern Europe, including 248 patients with erosive esophagitis (aged 46.5 ± 16.3 years) and 273 controls (aged 46.4 ± 16.0 years; response rate: 70%) enrolled during the period January 2013-June 2014. Both cases and controls underwent upper endoscopy. Information on socio-demographic characteristics and lifestyle factors was also collected. Binary logistic regression was used to assess the association of erosive esophagitis and extra-esophageal symptoms. RESULTS: Patients with erosive esophagitis had a higher prevalence of excessive alcohol consumption, smoking, sedentarity, non-Mediterranean diet and obesity compared to their control counterparts (9% vs. 5%, 70% vs. 49%, 31% vs. 17%, 61% vs. 49% and 22% vs. 9%, respectively). Upon adjustment for all socio-demographic characteristics and lifestyle/behavioral factors, there was evidence of a strong association of erosive esophagitis with chronic cough (OR = 3.2, 95% CI = 1.7-5.8), and even more so with laryngeal disorders (OR = 4.4, 95% CI = 2.6-7.5). In all models, the association of erosive esophagitis with any extra-esophageal symptoms was strong and mainly consistent with each of the symptoms separately (fully-adjusted model: OR = 4.6, 95% CI = 2.9-7.3). CONCLUSION: Our findings indicate that the prevalence of extra-esophageal symptoms is higher among patients with erosive esophagitis in a transitional country characterized conventionally by employment of a Mediterranean diet.

Esophagitis Dissecans Superficialis in Children.

OBJECTIVES: Esophagitis dissecans superficialis (EDS) is a desquamative disorder of the superficial esophageal epithelium with variable clinical characteristics. Endoscopically, there is an appearance of superficial peeling of sheets of epithelium. Histologically there is 2-toned epithelium with coagulative necrosis of the superficial epithelium. Currently, there is paucity of data regarding this condition in children. METHODS: A 10-year retrospective search of the pathology information system was performed for cases with a pathologic diagnosis of EDS in a tertiary care pediatric center. Demographic data, clinical history, endoscopic findings, and histopathologic reports were reviewed. RESULTS: Thirteen patients (9 girls; ages 3-18 years), were identified with histologic findings of EDS. Esophageal food impaction, dysphagia, vomiting, and abdominal pain were the most common presenting symptoms. Sixty-nine percentage of the patients had underlying comorbidities and 76% were on at least 1 medication chronically. Eosinophilic esophagitis (23%), inflammatory bowel disease (23%), and gastroesophageal reflux disease (GERD) (15%) were the most common associated diagnoses. Of the 13 patients, 5 had repeat endoscopies showing complete resolution of EDS with no complications. CONCLUSIONS: EDS is an under-recognized entity that endoscopists should be familiar with. In our series, the most prevalent associations were with food impaction and eosinophilic esophagitis (EoE). Contact injury and/or inflammation may precede the development of EDS. Pediatric EDS appears to be an incidental finding without significant morbidity or mortality.

Dietary Habits and Risk of Esophagitis and Barrett's Esophagus: A Multicenter Italian Case-Control Study.

BACKGROUND: Barrett's esophagus (BE) and esophagitis share potentially modifiable risk factors such as obesity, smoking, and alcohol. The role of diet on BE and esophagitis is still debated. AIMS: The objective of this study was to examine the association between some dietary habits and the risk of BE and esophagitis in Italy. METHODS: A multicenter case-control study involving 1285 individuals was carried out in 12 areas. Patients with a new diagnosis of BE (320) or esophagitis (359) and a group of endoscopic controls (606) were included. Information on personal history and dietary habits was collected using a structured questionnaire. RESULTS: No clear monotonic significant dose-response relationship was found for most of the considered food items. Nevertheless, the most extreme consumption category of red meat, cold cuts, dairy products, and fried foods showed esophagitis risk excesses varying from 19 to 49%. A higher fat rich diet seemed to increase risk by 49% for BE and 94% for esophagitis. A downward tendency in esophagitis (- 27%) and BE risk (- 20%) was found associated with higher frequency of fresh fruit intake. In addition, a statistically significant twofold increased risk for both BE and esophagitis was found for subjects eating late evening snacks more than once every three days in comparison with the lowest intake category (no consumption). CONCLUSIONS: BE and esophagitis patients appeared to be more likely than controls to follow a diet rich in fats and poor in fruit and vegetables. Late evening snacks were found to be associated with both disorders.

Risk Factors, Endoscopic Features, and Clinical Outcomes of Cytomegalovirus Esophagitis Based on a 10-year Analysis at a Single Center.

Cytomegalovirus (CMV) can infect multiple areas of the gastrointestinal tract, most commonly the esophagus and colon.1 CMV esophagitis is the third leading cause of infectious esophagitis, after Candida and herpes simplex virus.2 It occurs predominantly in immunocompromised hosts such as patients with human immunodeficiency virus (HIV) and is considered an acquired immunodeficiency syndrome (AIDS) defining illness.1 However, more recent case reports suggest that this disease may also affect the non-HIV immunosuppressed patient population.3 The aim of this study was to reevaluate predictors for development of CMV esophagitis in the post highly active antiretroviral therapy era and describe clinical and endoscopic features of CMV esophagitis as well as patient outcomes from a large tertiary care center.

Potential roles of Helicobacter pylori treatment, body mass index and waist circumference in the causation of erosive esophagitis: a randomized clinical trial (HEROES-GERD).

BACKGROUND: In recent decades, the prevalence of gastroesophageal reflux disease (GERD) and obesity has been increasing while Helicobacter pylori infection has been decreasing. OBJECTIVE: To evaluate if H. pylori treatment, excess body weight and other anthropometric measurements are associated with incident erosive esophagitis, as a secondary objective of a trial which tested the efficacy of treatment of H. pylori on the symptoms of functional dyspepsia. SUBJECTS/METHODS: Upper gastrointestinal endoscopy and anthropometric assessments were performed, at baseline and after 12 months, in H. pylori positive patients with functional dyspepsia who had no baseline reflux symptoms or esophagitis. Patients were randomly assigned to receive omeprazole, amoxicillin, and clarithromycin (antibiotic group; n = 201) or omeprazole plus placebo (control group; n = 203). The primary outcome was the incidence of esophagitis 12 months after randomization, according to treatment groups, and the association of BMI and other anthropometric measurements. RESULTS: Four hundred and four patients were included (mean age, 46.1 years; 78.7% women). The 12-month follow-up endoscopic esophagitis rates for the antibiotic and control groups were 10.9% (22/201) and 9.4% (19/203), respectively (p = 0.60). The number needed to harm was 67. Baseline anthropometric measurements were performed in 94% (380/404) of patients. The 12-month follow-up esophagitis rates for overweight and normal body weight patients were 13.6% (29/213) and 6.0% (10/167), respectively (p = 0.015); rates for patients with and without increased baseline waist circumference were 15.4% (24/156) and 6.7% (15/224), respectively (p = 0.006). Following logistic regression, only the combination of increased baseline body mass index and waist, but not H. pylori treatment, was independently associated with new-onset esophagitis (OR 2.88; 95% CI: 1.28-6.45). CONCLUSIONS: Excess body weight and concomitant increased waist circumference, but not H. pylori treatment, predicts new-onset esophagitis.

Trends in gastroesophageal reflux disease in Japanese children and adolescents.

BACKGROUND: Although the prevalence of gastroesophageal reflux disease (GERD) has been increasing in Japan, little is known about the prevalence and severity of GERD in pediatric patients. This study compared the prevalence and severity of endoscopically proven GERD in pediatric patients seen at an endoscopy center in Japan over a 15-year period. METHODS: This was a retrospective chart review of Japanese children aged 5-18 years undergoing esophagogastroduodenoscopy for upper gastrointestinal symptoms or anemia between 2005 and 2019. The prevalence and severity of reflux esophagitis and endoscopic Barrett's esophagus were compared between the periods 2005-2012 and 2013-2019. RESULTS: A total of 564 patients were evaluated: 315 from 2005 to 2012 (mean ± SD) age 13.8 ± 3.0 (range, 5-18 years; 147 boys; and 249 from 2013 to 2019 (mean ± SD) 14.7 ± 2.8 (range, 5-18) years; 108 boys. Demographics and clinical features were similar between the two groups. The proportion with erosive esophagitis or endoscopic Barrett's esophagus increased significantly between the two periods (9.8% to 18.1% for GERD, P = 0.0045 and 2.5% to 9.6% for Barrett's esophagus, P = 0.0003). The proportion of GERD patients with endoscopic Barrett's esophagus also significantly increased between the two periods (24/45 [53.3%]) vs (8/31 [25.8%]), P = 0.017]. CONCLUSION: The prevalence and severity of endoscopically proven GERDs has significantly increased over the past 15 years at an endoscopy center in Japan. Detailed population-based studies are needed to assess whether this is occurring throughout Japan.

Course of Esophageal Candidiasis and Outcomes of Patients at a Single Center.

Candida infection in the gastrointestinal tract is most studied in immunocompromised patients. Patients without systemic immunodeficiency, however, may have esophageal candidiasis associated with antibiotic or steroid medication use, alcoholic consumption, diabetes mellitus, and esophageal stasis disorders such achalasia or scleroderma esophagus.1-5 This population has not been well studied. We aim to describe demographics, risk factors, and relevant clinical outcomes for patients with Candida esophagitis with an emphasis in systemically immunocompetent patients.

Physical Activity Protects Against the Risk of Erosive Esophagitis on the Basis of Body Mass Index.

GOAL: To determine whether physical activity lowers the risk for erosive esophagitis on the basis of body mass index (BMI). BACKGROUND: Although previous studies have shown that physical activity is closely associated with erosive esophagitis, these data may be confounded by obesity. STUDY: In this retrospective study, we included 182,409 patients who underwent an upper endoscopy and were diagnosed with erosive esophagitis. The impact of the amount and intensity of physical activity on the risk for erosive esophagitis was analyzed based on BMI groups. Subjects were classified into three BMI groups with equal numbers in each group. RESULTS: Overall, 10.3% (n=18,859) of patients were diagnosed with erosive esophagitis. After adjusting for confounding factors, a greater amount of exercise [lower tertile: odd ratio (OR), 0.86; 95% confidence interval (CI), 0.77-0.96; middle tertile: OR, 0.91; 95%, CI 0.84-1.00; upper tertile: OR, 0.79; 95% CI, 0.73-0.85) and increased exercise intensity (lower tertile, moderate: OR, 0.61; 95% CI, 0.52-0.71; vigorous: OR, 0.51; 95% CI, 0.44-0.58; middle tertile, moderate: OR, 0.62; 95% CI, 0.55-0.70; vigorous: OR, 0.58; 95% CI, 0.51-0.65; upper tertile, moderate: OR, 0.58; 95% CI, 0.53-0.65; vigorous: OR, 0.58; 95% CI, 0.53-0.64) was associated with a decreased risk for erosive esophagitis in all 3 BMI groups. In addition, we observed that increased physical activity intensity notably decreased the risk for erosive esophagitis in subjects performing lesser physical activity, but slightly decreased the risk for erosive esophagitis in subjects performing more physical activity. CONCLUSION: Physical activity is inversely associated with erosive esophagitis.

Treatment of newly-diagnosed gastroesophageal reflux disease: a nationwide register-based cohort study.

Objective: The aim of this study was to describe short-term treatment of gastroesophageal reflux disease (GERD) in patients registered with a GERD-diagnosis as part of evaluation with endoscopy using national Danish registers. Methods: The study population included all adults undergoing upper gastrointestinal endoscopy in Denmark from 1 January 2000 to 31 December 2015, who within 90 days received a diagnosis of GERD. We obtained nationwide data from The National Patient Registry on procedures (endoscopy and anti-reflux surgery) and diagnosis (GERD diagnosis and comorbidity), The Danish National Prescription Registry on the use of anti-reflux medication and ulcerogenic drugs, and The National Civil Registry on death and civil status. The primary outcome was a type of treatment of GERD within two years of primary endoscopy defined as either no treatment, medical treatment alone, surgical treatment alone or both medical and surgical treatment. Results: A total of 36,292 patients were included in the study. Endoscopies were performed without biopsies in 67.5% (n = 24,479) of cases. The majority (66.3%, n = 24,077) was registered as GERD with esophagitis. After initial endoscopy, 10.6% (n = 3862) received no pharmacological or surgical treatment for GERD within two years of follow-up, 87.5% (n = 31,761) received only pharmacological treatment, 0.1% (n = 50) received only surgical treatment and 1.7% (n = 619) received a combination of pharmacological and surgical treatment. Conclusion: Patients referred to investigation with endoscopy and diagnosed with GERD in Denmark are primarily treated with pharmacological anti-reflux treatment within the first two years with PPI being the primary agent. Only a small fraction of patients is treated surgically.
