Abstract
Background Immunopathology in food allergy is characterized by an uncontrolled type 2 immune response and specific-IgE production. Recent studies have determined that group 2 innate lymphoid cells (ILC2) participate in the food allergy pathogenic mechanism and their severity. Our objective was to investigate the role of ILC2 in peach-allergic patients due to non-specific lipid transfer protein (Pru p 3) sensitization. Methods The immune response in peripheral blood mononuclear cells was characterized in lipid transfer protein-allergic patients and healthy controls. We have analyzed the Pru p 3 uptake on ILC2, the expression of costimulatory molecules, and their involvement on the T-cell proliferative response and cytokine production under different experimental conditions: cytokines involved in group 2 innate lymphoid cell activation (IL-33 and IL-25), Pru p 3 as main food allergen, and the combination of both components (IL-33/IL-25+Pru p 3) using cell sorting, EliSpot, flow cytometry, and confocal microscopy. Results Our results show that Pru p 3 allergen is taken up by group 2 innate lymphoid cells, regulating their costimulatory molecule expression (CD83 and HLA-DR) depending on the presence of Pru p 3 and its combination with IL-33/IL-25. The Pru p 3-stimulated ILC2 induced specific GATA3+Th2 proliferation and cytokine (IL-4, IL-5, and IL-13) production in lipid transfer protein-allergic patients in a cell contact-dependent manner with no changes in Tbet+Th1- and FOXP3+Treg cell differentiation. Conclusions The results indicate that in lipid transfer protein-allergic patients, the responsible allergen, Pru p 3, interacts with group 2 innate lymphoid cells, promoting a Th2 cell response. Our results might be of interest in vivo, as they show a role of group 2 innate lymphoid cells as antigen-presenting cells, contributing to the development of food allergy. Consequently, group 2 innate lymphoid cells may be considered as potential therapeutic targets.

Abstract
PURPOSE OF REVIEW Food allergies are immune-mediated, complex disorders, which are the source of increasing health concern worldwide. The goal of this review is to present an updated summary of the food allergy (FA) burden among children and adults across different populations, focusing on research from the past 5 years. RECENT FINDINGS FAs impact a growing number of global residents-particularly those residing in higher-income, industrialized regions. Moreover, growing epidemiologic evidence suggests that the population health burden of non-IgE-mediated FAs, such as food protein-induced enterocolitis syndrome, may also be higher than previously reported. FA is a complex trait that impacts infants, children, as well as adults across the globe. The population health burden of both IgE- and non-IgE-mediated FAs is likely to grow in the absence of rapid advances and widespread implementation of effective FA prevention and treatment interventions. Systematic epidemiological research initiatives are needed, both nationally and globally, to better understand and reduce the burden of these allergic diseases.

Eosinophilic esophagitis is associated with increased risk of later inflammatory bowel disease in a nationwide Swedish population cohort. United European Gastroenterol J 2024; 12:34-43. [PMID: 38058270 PMCID: PMC10859712 DOI: 10.1002/ueg2.12493] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Accepted: 10/20/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND Earlier studies on the possible association between eosinophilic esophagitis (EoE) and inflammatory bowel disease (IBD) have been contradictory. METHODS Patients with biopsy-verified EoE diagnosed between 1990 and 2017 in Sweden (n = 1587) were age- and sex-matched with up to five general population reference individuals (n = 7808). EoE was defined using pathology reports from all 28 pathology centers in Sweden (the ESPRESSO study). Multivariate Cox regression then estimated hazard ratios for future IBD. IBD was defined based on the international classification of disease codes and histopathology codes. In secondary analyses, sibling comparators were used to further reduce potential familial confounding. Additionally, we performed logistic regression examining earlier IBD in EoE. RESULTS During follow-up until 2020, 16 (0.01%) EoE patients and 21 (0.003%) general population reference individuals diagnosed with IBD, corresponding to a 3.5-fold increased risk of future IBD (aHR = 3.56; 95% CI 1.79-7.11). EoE was linked to Crohn's disease (aHR = 3.39 [95% CI 1.02-9.60]) but not to ulcerative colitis (aHR = 1.37; 95% CI 0.38-4.86). Compared to their siblings, patients with EoE were at a 2.48-fold increased risk of IBD (aHR = 2.48; 95% CI 0.92-6.70). Earlier IBD was 15 times more likely in EoE patients than in matched reference individuals (odds ratio, 15.39; 95% CI 7.68-33.59). CONCLUSION In this nationwide cohort study, EoE was associated with a 3.5-fold increased risk of later IBD diagnosis. This risk increase may be due to shared genetic or early environmental risk factors, but also surveillance bias could play a role.

Abstract
Eosinophilic esophagitis (EoE) is a rare atopic disorder associated with esophageal dysfunction, including difficulty swallowing, food impaction, and inflammation, that develops in a small subset of people with food allergies. Genome-wide association studies (GWASs) have identified 9 independent EoE risk loci reaching genome-wide significance (p < 5 × 10-8) and 27 additional loci of suggestive significance (5 × 10-8 < p < 1 × 10-5). In the current study, we perform linkage disequilibrium (LD) expansion of these loci to nominate a set of 531 variants that are potentially causal. To systematically interrogate the gene regulatory activity of these variants, we designed a massively parallel reporter assay (MPRA) containing the alleles of each variant within their genomic sequence context cloned into a GFP reporter library. Analysis of reporter gene expression in TE-7, HaCaT, and Jurkat cells revealed cell-type-specific gene regulation. We identify 32 allelic enhancer variants, representing 6 genome-wide significant EoE loci and 7 suggestive EoE loci, that regulate reporter gene expression in a genotype-dependent manner in at least one cellular context. By annotating these variants with expression quantitative trait loci (eQTL) and chromatin looping data in related tissues and cell types, we identify putative target genes affected by genetic variation in individuals with EoE. Transcription factor enrichment analyses reveal possible roles for cell-type-specific regulators, including GATA3. Our approach reduces the large set of EoE-associated variants to a set of 32 with allelic regulatory activity, providing functional insights into the effects of genetic variation in this disease.

Immunoglobulin G4 in eosinophilic esophagitis: Immune complex formation and correlation with disease activity. Allergy 2023; 78:3193-3203.

Abstract
BACKGROUND Recent studies have shown deposition of immunoglobulin G4 (IgG4) and food proteins in the esophageal mucosa of eosinophilic esophagitis (EoE) patients. Our aims were to assess whether co-localization of IgG4 and major cow's milk proteins (CMPs) was associated with EoE disease activity and to investigate the proteins enriched in proximity to IgG4 deposits. METHODS This study included adult subjects with EoE (n = 13) and non-EoE controls (n = 5). Esophageal biopsies were immunofluorescence stained for IgG4 and CMPs. Co-localization in paired samples from active disease and remission was assessed and compared to controls. The proteome surrounding IgG4 deposits was evaluated by the novel technique, AutoSTOMP. IgG4-food protein interactions were confirmed with co-immunoprecipitation and mass spectrometry. RESULTS IgG4-CMP co-localization was higher in the active EoE group compared to paired remission samples (Bos d 4, p = .02; Bos d 5, p = .002; Bos d 8, p = .002). Co-localization was also significantly higher in the active EoE group compared to non-EoE controls (Bos d 4, p = .0013; Bos d 5, p = .0007; Bos d 8, p = .0013). AutoSTOMP identified eosinophil-derived proteins (PRG 2 and 3, EPX, RNASE3) and calpain-14 in IgG4-enriched areas. Co-immunoprecipitation and mass spectrometry confirmed IgG4 binding to multiple food allergens. CONCLUSION These findings further contribute to the understanding of the interaction of IgG4 with food antigens as it relates to EoE disease activity. These data strongly suggest the immune complex formation of IgG4 and major cow's milk proteins. These immune complexes may have a potential role in the pathophysiology of EoE by contributing to eosinophil activation and disease progression.

Abstract
INTRODUCTION Food allergies (FA) can detrimentally impact physical, emotional, and psychological quality of life (QoL) among pediatric patients. Given the changes from childhood into adolescence, the impact of FA on QoL likely evolves with age. The purpose of this study was to determine whether QoL differed between adolescents and children with FA who participated in a Food Allergy Symposium (FAS). METHODS Patients with confirmed FA were recruited at an educational community symposium in September 2018 and September 2019. Patients and/or their parents were invited to complete the Food Allergy Quality of Life Questionnaires (FAQLQ). The Food Allergy Independent Measure (FAIM) reflects concerns about accidental food exposure and disease severity. Higher FAIM and FAQLQ scores reflect worse QoL. Summary scores were compared using the Wilcoxon rank sum test, Fisher's exact test, or the Chi-square test. RESULTS Seventy-four surveys (82% children, 18% adolescents) were included. The FAQLQ total score was higher among adolescents than children (median 5.2 vs 4.2; p = 0.045), and the FAIM was lower in adolescents (median 2.2 vs 2.8; p = 0.037). More adolescents reported previous anaphylaxis than children (91.7% vs 51.8%; p = 0.011). The percentage reassured by having epinephrine was higher in adolescents (81.8% vs 45.8%; p = 0.046). No other QoL scores and survey responses were significantly different. DISCUSSION In this study, adolescents were more concerned about their disease and more reassured by epinephrine carriage than younger children, which may reflect increased autonomy and responsibility. Community events are an important way to assess QoL and provide FA-related education to pediatric patients.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) can coexist in individuals with food allergy. OBJECTIVE To evaluate the characteristics of food-allergic patients with and without coexisting EoE using a large food allergy patient registry. METHODS Data were derived from 2 Food Allergy Research & Education, Inc, Patient Registry surveys. A series of multivariable regression models were used to evaluate associations between demographic, comorbidity, and food allergy characteristics and the likelihood of reporting EoE. RESULTS Five percent (n = 309) of registry participants (n = 6074; ages <1 year->80 years, mean, 20.20 ± 15.37 years) reported having EoE. The odds of having EoE were significantly greater in male participants (adjusted odds ratio [aOR], 1.3; 95% CI, 1.04-1.72) and those with comorbid asthma (aOR, 2.0; 95% CI, 1.55-2.49), allergic rhinitis (aOR, 1.8; 95% CI, 1.37-2.22), oral allergy syndrome (aOR, 2.8; 95% CI, 2.09-3.70), food protein-induced enterocolitis syndrome (aOR, 2.5; 95% CI, 1.34-4.84), and hyper-IgE syndrome (aOR, 7.6; 95% CI, 2.93-19.92), though not atopic dermatitis (aOR, 1.3; 95% CI, 0.99-1.59), when adjusting for demographics (sex, age, race, ethnicity, and geographic location). Those with a greater number of food allergies (aOR, 1.3; 95% CI, 1.23-1.32), more frequent food-related allergic reactions (aOR, 1.2; 95% CI, 1.11-1.24), previous anaphylaxis (aOR, 1.5; 95% CI, 1.15-1.83), and health care utilization for food-related allergic reactions (aOR, 1.3; 95% CI, 1.01-1.67)-specifically intensive care unit admission (aOR, 1.2; 95% CI, 1.07-1.33)-were more likely to have EoE after controlling for demographics. However, no significant difference in ever using epinephrine for food-related allergic reactions was detected. CONCLUSIONS These self-reported data showed that coexisting EoE is associated with an increased number of food allergies, food-related allergic reactions per year, and measures of reaction severity, calling attention to the likely increased health care needs of food-allergic patients with EoE.

Abstract
BackgroundEosinophilic oesophagitis (EoE) is a chronic food allergic disorder limited to oesophageal mucosa whose pathogenesis is still only partially understood. Moreover, its diagnosis and follow-up need repeated endoscopies due to absence of non-invasive validated biomarkers. In the present study, we aimed to deeply describe local immunological and molecular components of EoE in well-phenotyped children, and to identify potential circulating EoE-biomarkers.MethodsBlood and oesophageal biopsies were collected simultaneously from French children with EoE (n=17) and from control subjects (n=15). Untargeted transcriptomics analysis was performed on mRNA extracted from biopsies using microarrays. In parallel, we performed a comprehensive analysis of immune components on both cellular and soluble extracts obtained from both biopsies and blood, using flow cytometry. Finally, we performed non-targeted plasma metabolomics using liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS). Uni/multivariate supervised and non-supervised statistical analyses were then conducted to identify significant and discriminant components associated with EoE within local and/or systemic transcriptomics, immunologic and metabolomics datasets. As a proof of concept, we conducted multi-omics data integration to identify a plasmatic signature of EoE.ResultsFrench children with EoE shared the same transcriptomic signature as US patients. Network visualization of differentially expressed (DE) genes highlighted the major dysregulation of innate and adaptive immune processes, but also of pathways involved in epithelial cells and barrier functions, and in perception of chemical stimuli. Immune analysis of biopsies highlighted EoE is associated with dysregulation of both type (T) 1, T2 and T3 innate and adaptive immunity, in a highly inflammatory milieu. Although an immune signature of EoE was found in blood, untargeted metabolomics more efficiently discriminated children with EoE from control subjects, with dysregulation of vitamin B6 and various amino acids metabolisms. Multi-blocks integration suggested that an EoE plasma signature may be identified by combining metabolomics and cytokines datasets.ConclusionsOur study strengthens the evidence that EoE results from alterations of the oesophageal epithelium associated with altered immune responses far beyond a simplistic T2 dysregulation. As a proof of concept, combining metabolomics and cytokines data may provide a set of potential plasma biomarkers for EoE diagnosis, which needs to be confirmed on a larger and independent cohort.

Eosinophilic Esophagitis—What Do We Know So Far? J Clin Med 2023; 12:jcm12062259.

Abstract
Eosinophilic esophagitis is a Th-2 antigen-mediated disease in which there is an influx of eosinophils to all layers of the esophagus, triggering an inflammatory response. Chronic inflammatory process causes esophageal remodeling, leading to difficulties in swallowing. Food impaction, heartburn, and chest pain are other characteristic (but not pathognomonic) symptoms in adults. Although the disease has only been described since in the early 1970s, its incidence and prevalence are rapidly growing, especially in Western countries. According to the diagnostic guidelines, there should be at least 15 eosinophils visible per high-power field in biopsies obtained from different sites in the esophagus upon endoscopy with relevant esophageal symptoms. Other diseases that can cause esophageal eosinophilia should be ruled out. Eosinophilic esophagitis treatment may be challenging; however, new methods of management have recently emerged. The currently used proton pump inhibitors, topical corticosteroids, and elimination diet are combined with biological treatment. New methods for disease diagnostics and clinical course assessment are also available. This review presents current knowledge about the disease, supported by the latest research data.

Abstract
An immunocompetent man in his 20s presented with a 24-hour history of severe odynophagia, nausea, vomiting and throat pain. Esophagogastroduodenoscopy (EGD) revealed severe esophagitis with ulcerated mucosa, exudative debris, haemorrhage and multiple erosions. Biopsy of the oesophageal tissue demonstrated marginated chromatin, multinucleated giant cells and molding of nuclei, consistent with herpes simplex virus esophagitis (HSE). Treatment with oral acyclovir led to the complete resolution of symptoms. The patient subsequently developed dysphagia again, 8 months later. EGD showed furrowing and concentric rings typical of eosinophilic esophagitis (EoE), a diagnosis confirmed by biopsy. Treatment with a proton pump inhibitor and swallowed topical corticosteroids led to symptomatic improvement. Thus, HSE can occur in immunocompetent hosts and on occasion, HSE may be a harbinger of EoE, as evidenced by our extensive literature review. Mechanical disruption of the mucosal barrier by viruses, facilitating food allergen penetration, and associated immunological signaling abnormalities may be responsible phenomena requiring further elucidation.

Abstract
Eosinophilic esophagitis (EoE), a chronic inflammatory disease of the esophagus, has been increasing in incidence over the past several years. Mainstays of treatment include dietary modifications, steroids, proton pump inhibitors (PPIs), and endoscopic dilation, with the goal being to control disease progression, promote remission, and alleviate symptoms, such as dysphagia and food impaction. In addition to these well-known treatment options, preliminary studies on new medications that target specific inflammatory mediators involved in the pathogenesis of EoE have shown promise in improving symptoms. This review article summarizes and discusses the application and efficacy of long-standing and promising new treatment options for EoE.

Abstract
Eosinophilic esophagitis (EoE) is an inflammatory condition of the esophagus that causes symptoms of esophageal dysmotility. Patients with feeding or eating disorders (ED) can have similar symptoms, and there is a paucity of literature exploring these similarities. Furthermore, EoE can occur in addition to an ED, requiring clinicians to obtain a thorough history, make accurate diagnoses, and adequately treat all underlying conditions. We present 4 pediatric cases highlighting the similarities between EoE and ED symptomatology. Patients 1 to 3 were presumed to have an ED and were subsequently diagnosed with EoE. Patient 4 had a history of previously diagnosed and inadequately treated EoE, but was later found to also have a longstanding ED. The patients presented to the University of Rochester Pediatric Ambulatory Clinics in 2020. This series demonstrates that symptoms of EoE can overlap with those of an ED, such as anorexia nervosa or avoidant restrictive food intake disorder. Therefore, assessment for either EoE or an ED should include questions related to both diagnoses. Symptoms that may raise suspicion of EoE are indigestion, acute (versus chronic) weight loss, and dysphagia, including the inability to swallow pills, particularly in the presence of personal or family history of atopy. Patients with known EoE should be periodically evaluated for the presence of an ED. This case series illustrates that EoE can either present as an ED or complicate the diagnosis and/or treatment of an ED, making prompt diagnosis and treatment essential for successful management of all conditions.

Abstract
Introduction: In recent years, the advent of immunotherapy has remarkably improved the management of IgE-mediated food allergy. However, some barriers still exist. Therefore, the effort of researchers aims to investigate new perspectives in the field of non-allergen specific therapy, also based on the current knowledge of the pathogenesis of this disease.Areas covered: This review aims to focus on the role of biologics as a treatment option in patients with IgE-mediated food allergy. These agents are characterized by their ability to inactivate the Th2 pro-inflammatory pathways. Biologics can be used both alone and in association with immunotherapy. Monoclonal antibodies targeting IgE, the IL-4/IL-13 axis, IL-5, and alarmins have been proposed and investigated for treating food allergy.Expert opinion: The clinical efficacy and safety of biologics have been demonstrated in several preclinical studies and randomized controlled trials. Future studies are still required to address current unmet needs, including the identification of the optimal dose to be used by ensuring the effectiveness of therapy.
