Diagnosis and management of eosinophilic esophagitis and esophageal food impaction in adults : A position paper issued by the Austrian Society of Gastroenterology and Hepatology (ÖGGH).

This position paper deals with an expert consensus on diagnosis and management of eosinophilic esophagitis and esophageal food impaction issued by the Austrian Eosinophilic Esophagitis Network, a working group under the patronage of the Austrian Society of Gastroenterology and Hepatology (ÖGGH). In need of a standardized approach on the management of EoE, recommendations were made based on international guidelines and landmark studies.

A Cricopharyngeal Bar as an Underrecognized Finding in an Adolescent with Eosinophilic Esophagitis.

A 16-year-old Caucasian male with previously diagnosed eosinophilic esophagitis (EoE) 4 years before his initial visit to an allergist-immunologist, scheduled due to severe dysphagia and recurrent food impaction. He had been off EoE therapy for 1 year. After resuming inhaled fluticasone and a proton pump inhibitor (PPI), esophagogastroduodenoscopy (EGD) was immediately scheduled. The dates of the original EGD procedures with the histological summary and EoE therapy are reported in the Table 1. The fourth endoscopy revealed near normal histology, with rare candida staining (Table 1). He was continued on daily PPI and the fluticasone was discontinued. Three weeks of Fluconazole failed to resolve his dysphagia. A repeat barium swallow confirmed a pre-existing cricopharyngeal bar, and he was referred to an otolaryngology for further care.

Analysis of the Association between Eosinophilic Esophagitis and MASLD: Retrospective, Observational, Cohort Analysis of the National Inpatient Sample 2016-2020.

BACKGROUND AND AIMS: Eosinophilic esophagitis (EoE) is a chronic immune-mediated inflammatory condition. Associated pathologies for EoE are similar to those with metabolic-dysfunction-associated steatotic liver disease (MASLD). This study assesses whether an association exists between MASLD and EoE. METHODS: We used National Inpatient Sample (NIS) 2020 data to identify adult patients. ICD-10 codes were used to identify patients with MASLD and EoE. The relationship between MASLD and EoE was assessed by multivariate analysis after adjusting for confounding factors, such as patient demographics, hospital characteristics, Charlson comorbidity index, obesity, obstructive sleep apnea (OSA), diabetes, hypertension (HTN), hyperlipidemia (HLD), inflammatory bowel disease (IBD), celiac disease (CD), gastroesophageal reflux disease (GERD), smoking, alcohol use, and irritable bowel syndrome (IBS). RESULTS: Out of 26 million patients, 4,820 had a diagnosis of EoE. The majority of the patients were between 18 and 44 years of age (47.82%), male (54.05%), had private insurance (50.1%), and were in the highest income quartile (29.25%). A higher incidence of MASLD was noted in the EoE group than those without (6.1% vs.2.9%, p<0.001). After adjusting for confounding factors, MASLD had 2.38 times higher odds of having EoE (95% CI-1.82-3.11, p<0.001). Other factors noted to be associated with higher odds of EoE included younger age, Caucasian race, IBS, GERD, IBD, and CD. CONCLUSIONS: Our study reports a novel finding that MASLD and EoE are associated. Future prospective studies are needed to confirm and understand the clinical significance of this relationship and how one disease affects the other.

Spontan øsofagusruptur.

Background: Spontaneous rupture of the oesophagus is a potentially fatal condition. Symptoms can vary and diagnosis can be challenging. Case presentation: A woman in her seventies presented to the emergency department with sudden-onset epigastric pain after a meal. A computed tomography (CT) showed signs of oesophageal rupture. Upper gastrointestinal endoscopy revealed an oesophageal rupture, and a stent was placed. The patient developed fever, dyspnoea and hypotension after the procedure. Additional CT revealed increasing pleural effusion, pneumomediastinum and loculaments of air in the peritoneum, and a mediastinal abscess. Laparoscopy with lavage and debridement was performed. A catheter was placed in the abscess and a chest tube in her right hemithorax. The stent was removed after 27 days. Further investigation revealed eosinophil oesophagitis as the likely cause of her oesophageal rupture. Interpretation: This case highlights the importance of early diagnosis and proper treatment of spontaneous oesophageal rupture. Treatment depends on the cause of the rupture and severity of the patient's condition.

[Eosinophilic esophagitis (EoE) in adults in Icelandic and international context].

Eosinophilic esophagitis (EoE) is a common cause of swallowing difficulties in both children and adults. The incidence of EoE has been increasing over the past decades, which cannot be solely attributed to improved diagnostic techniques. EoE is more common in adults than in children. The diagnosis is confirmed by a biopsy from the esophageal mucosa showing a significant infiltration of eosinophils. Many patients respond to treatment with proton pump inhibitors, but those with severe EoE may require dietary modifications, topical steroids, and/or dilation of esophageal strictures. This review covers the incidence, risk factors, natural course, diagnosis, and treatment options for EoE, both within the Icelandic healthcare system andi n a broader context.

[IgE- and non-IgE-mediated food allergies - an overview]. / IgE- und nicht IgE-vermittelte Nahrungsmittelallergien ­ ein Überblick.

Food allergies are divided into 2 main categories: IgE-mediated and non-IgE-mediated food allergies. Both forms can have significant health effects but differ in mechanism, symptoms, and management. The manifestation of the 2 forms differs between children and adults. These differences can be observed in the prevalence and the type of most common allergens and clinical presentation. The prevalence of food allergies has increased worldwide in recent decades. IgE-mediated allergies are the best researched and documented. They are particularly common in children, while non-IgE-mediated allergies are less well understood and diagnosed, leading to uncertainty about their prevalence. They often manifest as gastrointestinal symptoms that can occur hours to days after ingestion and are often difficult to distinguish from other food intolerances. The occurrence of food allergies varies significantly geographically. Differences in dietary habits, food composition, and environmental factors can partly explain these differences. There are also indications that genetics may play a role. IgE-mediated and non-IgE-mediated food allergies represent a significant and growing challenge for the global healthcare system. This article provides an in-depth review of both types of food allergy, discussing their potential causes, diagnostic possibilities, and available therapeutic strategies. Some diseases represent a mixed form of IgE and non-IgE-mediated immunological adverse reactions. Eosinophilic oesophagitis is the most common eosinophilic disease, and the diagnosis and treatment options are explained in more detail below.

Genomic insights into pediatric intestinal inflammatory and eosinophilic disorders using single-cell RNA-sequencing.

Introduction: Chronic inflammation of the gastrointestinal tissues underlies gastrointestinal inflammatory disorders, leading to tissue damage and a constellation of painful and debilitating symptoms. These disorders include inflammatory bowel diseases (Crohn's disease and ulcerative colitis), and eosinophilic disorders (eosinophilic esophagitis and eosinophilic duodenitis). Gastrointestinal inflammatory disorders can often present with overlapping symptoms necessitating the use of invasive procedures to give an accurate diagnosis. Methods: This study used peripheral blood mononuclear cells from individuals with Crohn's disease, ulcerative colitis, eosinophilic esophagitis, and eosinophilic duodenitis to better understand the alterations to the transcriptome of individuals with these diseases and identify potential markers of active inflammation within the peripheral blood of patients that may be useful in diagnosis. Single-cell RNA-sequencing was performed on peripheral blood mononuclear cells isolated from the blood samples of pediatric patients diagnosed with gastrointestinal disorders, including Crohn's disease, ulcerative colitis, eosinophilic esophagitis, eosinophilic duodenitis, and controls with histologically healthy gastrointestinal tracts. Results: We identified 730 (FDR < 0.05) differentially expressed genes between individuals with gastrointestinal disorders and controls across eight immune cell types. Discussion: There were common patterns among GI disorders, such as the widespread upregulation of MTRNR2L8 across cell types, and many differentially expressed genes showed distinct patterns of dysregulation among the different gastrointestinal diseases compared to controls, including upregulation of XIST across cell types among individuals with ulcerative colitis and upregulation of Th2-associated genes in eosinophilic disorders. These findings indicate both overlapping and distinct alterations to the transcriptome of individuals with gastrointestinal disorders compared to controls, which provide insight as to which genes may be useful as markers for disease in the peripheral blood of patients.

Standardizing visual display of gastrointestinal pathology results for improved clinical interpretation.

OBJECTIVES: Pathology is an essential component of disease diagnosis and management in pediatric gastroenterology. Pathology reports have not been standardized in some areas of pediatric gastrointestinal pathology and pathology reporting varies. Development of electronic medical record (EMR) pathology synoptic report templates (PSRT) enables pathology data collection in a specific format and can help standardize pathology reporting. We developed, implemented, and evaluated EMR PSRTs for eosinophilic esophagitis (EoE) and inflammatory bowel disease (IBD). METHODS: PSRTs were developed by a multidisciplinary team of pediatric experts of allergy, gastroenterology, and pathology for both EoE and IBD based on available literature and validated scales. Likert surveys (range 1 low acceptance to 5 high acceptance) based on the Technology Acceptance Model assessed user acceptance of the developed PSRTs. The use of PSRTs was monitored via control charts. RESULTS: Overall, evaluation questionnaires achieved >80% response rates. Clinicians and pathologists reported moderate-to-high levels of Perceived Usefulness (median (interquartile range) for EoE PSRT: clinicians 4.0 (4.0, 5.0) and pathologists 3.5 (3.5, 4.0); and IBD PSRT: clinicians 4.0 (3.0, 4.0) and pathologists 4.0 (4.0, 5.0)) and Perceived Ease of Use (EoE PSRT: clinicians 4.5 (4.0, 5.0) and pathologists 4.0 (4.0, 4.0); and IBD PSRT: clinicians 4.0 (4.0, 5.0) and pathologists 4.0 (4.0, 5.0)) of the developed PSRTs. Control charts demonstrated 100% utilization by 2-5 months from launch. CONCLUSIONS: We demonstrate successful implementation of synoptic reporting for both pediatric EoE and IBD pathology. EMR synoptic reporting provides standardization of pathology reporting and improved methods of pathology data presentation, which could potentially optimize provider efficiency, clinician interpretation of pathology results and disease trajectory, patient care, and clinician satisfaction.

Losartan Treatment Reduces Esophageal Eosinophilic Inflammation in a Subset of Eosinophilic Esophagitis.

BACKGROUND: Eosinophilic esophagitis (EoE) is a chronic, food antigen-driven esophageal disorder. Connective tissue disorders (CTDs) and esophageal connective tissue alterations are associated with EoE. Therefore, angiotensin II type 1 receptor blockade with losartan, an accepted CTD treatment, is a potential EoE treatment. OBJECTIVE: We evaluated losartan's effects on esophageal pathology, symptoms, and safety in patients with EoE with and without a CTD in an open-label, non-placebo controlled multisite study. METHODS: Fifteen participants with EoE, aged 5 to 23 years, underwent treatment with per-protocol titrated doses of losartan in an open-label, 16-week pilot trial. Losartan was added to standard of care therapy and 14 patients completed the study. Eosinophil counts served as the primary end point, whereas we also assessed the EoE Histology Scoring System, Endoscopic Reference Scores, EoE Diagnostic Panel, and patient-reported outcomes. RESULTS: Esophageal eosinophilia was not reduced after losartan. The peak eosinophil count was not reduced for the proximal (median [interquartile range]: -3 [-22 to 3]; P = .49) and distal esophagus (median [interquartile range]: -18 [-39 to -1]; P = .23). There were no differences in losartan response in EoE with or without CTD (n = 7 and 8, respectively). Regardless, in a small subset of four participants esophageal eosinophilia was resolved with a concomitant reduction in EoE Histology Scoring System score and Endoscopic Reference Score. Across all subjects, the Pediatric EoE Symptom Score, Pediatric Quality of Life Inventory EoE Module, and EoE Diagnostic Panel improved after losartan (P < .05). CONCLUSIONS: Losartan treatment was associated with improved patient-reported outcome scores and EoE Diagnostic Panel biomarkers although without a reduction in esophageal eosinophilia overall. A subset of patients demonstrated improved histopathologic and endoscopic features that could not be tied to a specific feature predicting response to treatment.

Patients with cardinal symptoms of eosinophilic esophagitis. Prejudice affects clinical practice .

INTRODUCTION: Dysphagia and bolus impaction are the cardinal manifestations of eosinophilic esophagitis (EoE). Esophageal biopsy sampling is mandatory for EoE diagnosis, data though suggest that clinician do not always obtain biopsies from patients with cardinal EoE symptoms during upper gastrointestinal endoscopy even if no other entity than EoE can explain patients symptoms. We aimed to search for the esophageal biopsy procurement rate as also for factors that drive clinicians to obtain esophageal biopsies among patients with cardinal EoE symptoms. METHODS: We retrospectively searched for patients with cardinal EoE symptoms submitted to upper gastrointestinal endoscopy between 1/2018 and 12/2023 in our department. Epidemiologic, clinical, endoscopic, and histological data were analyzed. RESULTS: In total 163 patients with cardinal EoE symptoms (dysphagia: 63 and bolus impaction: 100) were included in the study (M/F: 100/63, mean age: 54 ±â€…22 years). Biopsy sampling was obtained in 77/163 (47.2%) patients and sampling rates did not differ between patients with bolus impaction or dysphagia (47/100, 47% vs 30/63, 47.6%, P  = 0.553). Higher rates of sampling were observed in males ( P  = 0.045), those younger than 65 years old ( P  < 0.001) and patients with endoscopic EoE signs ( P  = 0.004). Age and endoscopic findings compatible to EoE were independently correlated to biopsy sampling. EoE was diagnosed in 35/74 patients (47.3%); the majority of patients were male, with a bolus impaction episode, compatible endoscopic findings and all were younger than 65 years old. CONCLUSION: Clinicians take esophageal biopsies in half of patients with cardinal EoE. Age and supportive endoscopic evidence drive clinicians' decision to obtain esophageal biopsies.

Utilization and impact of esophageal string testing in children with eosinophilic esophagitis: A 1 year experience.

The 1-h esophageal string test (EST) is a minimally invasive test that can be used to monitor eosinophilic esophagitis (EoE) disease activity and guide treatment without endoscopy. We aimed to describe the real-world utilization and impact of EST on the care of children with EoE over the first year this was used at our center. Between 12/1/2022 and 11/30/2023, 39 ESTs were successful in 45 attempts (87% completion rate) in 31 patients. Five patients underwent multiple ESTs. Adverse events during the EST included vomiting. Reasons for failure to complete the EST (13%, n = 6) were patients could not swallow the capsule (n = 5) and vomiting (n = 1). EST was used to assess EoE without the need for endoscopy in 95% (n = 37) of cases. Treatment approach varied based on whether the EST indicated active (38.5%) or inactive (61.5%) EoE. The EST is a well-tolerated minimally invasive disease monitoring tool for patients with EoE.
