Microbiota profiling in esophageal diseases: Novel insights into molecular staining and clinical outcomes. Comput Struct Biotechnol J 2024; 23:626-637. [PMID: 38274997 PMCID: PMC10808859 DOI: 10.1016/j.csbj.2023.12.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 12/22/2023] [Accepted: 12/23/2023] [Indexed: 01/27/2024] Open
Abstract
Gut microbiota is recognized nowadays as one of the key players in the development of several gastro-intestinal diseases. The first studies focused mainly on healthy subjects with staining of main bacterial species via culture-based techniques. Subsequently, lots of studies tried to focus on principal esophageal disease enlarged the knowledge on esophageal microbial environment and its role in pathogenesis. Gastro Esophageal Reflux Disease (GERD), the most widespread esophageal condition, seems related to a certain degree of mucosal inflammation, via interleukin (IL) 8 potentially enhanced by bacterial components, lipopolysaccharide (LPS) above all. Gram- bacteria, producing LPS), such as Campylobacter genus, have been found associated with GERD. Barrett esophagus (BE) seems characterized by a Gram- and microaerophils-shaped microbiota. Esophageal cancer (EC) development leads to an overturn in the esophageal environment with the shift from an oral-like microbiome to a prevalently low-abundant and low-diverse Gram--shaped microbiome. Although underinvestigated, also changes in the esophageal microbiome are associated with rare chronic inflammatory or neuropathic disease pathogenesis. The paucity of knowledge about the microbiota-driven mechanisms in esophageal disease pathogenesis is mainly due to the scarce sensitivity of sequencing technology and culture methods applied so far to study commensals in the esophagus. However, the recent advances in molecular techniques, especially with the advent of non-culture-based genomic sequencing tools and the implementation of multi-omics approaches, have revolutionized the microbiome field, with promises of implementing the current knowledge, discovering more mechanisms underneath, and giving insights into the development of novel therapies aimed to re-establish the microbial equilibrium for ameliorating esophageal diseases..

Abstract
Cancer represents a major global public health burden, with new cases estimated to increase from 14 million in 2012 to 24 million by 2035. Primary prevention is an effective strategy to reduce the costs associated with cancer burden. For example, measures to ban tobacco consumption have dramatically decreased lung cancer incidence and vaccination against human papillomavirus can prevent cervical cancer development. Unfortunately, the etiological factors of many cancer types are not completely clear or are difficult to actively control; therefore, the primary prevention of such cancers is not practical. In this review, we update the progress on precision therapy by targeting the whole carcinogenesis process, especially for three high-risk groups: (1) those with chronic inflammation, (2) those with inherited germline mutations, and (3) those with precancerous lesions like polyps, gastritis, actinic keratosis or dysplasia. We believe that attenuating chronic inflammation, treating precancerous lesions, and removing high-risk tissues harboring germline mutations are precision methods for cancer prevention.

Abstract
GOALS To determine long-term efficacy and safety of tCS for treatment of EoE. BACKGROUND Maintenance therapy with topical corticosteroids (tCS) is recommended for eosinophilic esophagitis (EoE), but data for long-term use are still needed. STUDY This retrospective cohort study assessed newly diagnosed patients with EoE who were treated with a tCS and had a follow-up endoscopy with biopsy after at least 5 years. Histologic symptomatic and endoscopic responses were extracted from medical records. Patients who did and did not have long-term tCS treatment were compared at baseline, and outcomes for patients were assessed at their last endoscopy while on tCS. RESULTS Of 431 patients with EoE treated with tCS, 104 met inclusion criteria for long-term use. For patients with long-term tCS use, the median time (IQR) on tCS was 6.5 years (5.4 to 8.8 y). At the last endoscopy, 54% had histologic response (<15 eos/hpf), but those with excellent adherence had a histologic response of 64%. Endoscopic severity also decreased with improved adherence which was strongly associated with EREFS (1.7 vs. 2.8 vs. 4.0 for excellent, good, and poor adherence; P<0.001). Symptomatic response was 68% overall, but only 40% in those with poor adherence (P=0.07). Complications of taking tCS were uncommon (adrenal insufficiency: 1%; osteopenia: 1%; and esophageal candidiasis: 4% at final endoscopy). CONCLUSIONS Long-term tCS (median 6.5 y) were generally effective, especially with better adherence, and also safe, with only rare serious complications. These data can be used to help patients make clinical decisions about chronic tCS use in EoE.

Abstract
The prevalence of many chronic noncommunicable diseases has been steadily rising over the past six decades. During this time, over 350,000 new chemical substances have been introduced to the lives of humans. In recent years, the epithelial barrier theory came to light explaining the growing prevalence and exacerbations of these diseases worldwide. It attributes their onset to a functionally impaired epithelial barrier triggered by the toxicity of the exposed substances, associated with microbial dysbiosis, immune system activation, and inflammation. Diseases encompassed by the epithelial barrier theory share common features such as an increased prevalence after the 1960s or 2000s that cannot (solely) be accounted for by the emergence of improved diagnostic methods. Other common traits include epithelial barrier defects, microbial dysbiosis with loss of commensals and colonization of opportunistic pathogens, and circulating inflammatory cells and cytokines. In addition, practically unrelated diseases that fulfill these criteria have started to emerge as multimorbidities during the last decades. Here, we provide a comprehensive overview of diseases encompassed by the epithelial barrier theory and discuss evidence and similarities for their epidemiology, genetic susceptibility, epithelial barrier dysfunction, microbial dysbiosis, and tissue inflammation.

Abstract
BACKGROUND A combination of proton-pump inhibitors (PPI) and topical steroids (TS) is used to treat children with eosinophilic esophagitis (EoE). However, a subset of children do not respond to this combination therapy. We aimed to identify the esophageal transcriptional, cell composition, and microbial differences between the non-responders (EoE-PPI-TSnr; n = 7) and responders (EoE-PPI-TSr; n = 7) to the combination therapy for EoE and controls (n = 9) using metatranscriptomics. METHODS Differential gene expression analysis was used to identify transcriptional differences, validated using the EoE diagnostic panel (EDP). Deconvolution analysis was performed to identify differences in their cell type composition. Microbiome analysis was conducted from esophageal biopsies RNAseq data, and microbial abundance was correlated with esophageal gene expression. RESULTS In all, 3164 upregulated and 3154 downregulated genes distinguished EoE-PPI-TSnr from EoE-PPI-TSr. Eosinophilic inflammatory response, cytokine signaling, and collagen formation pathways were significantly upregulated in EoE-PPI-TSnr. There was a 56% overlap in dysregulated genes between EoE-PPI-TSnr and EDP, with a perfect agreement in the directionality of modulation. Eosinophils, dendritic cells (DCs), immature DCs, megakaryocytic-erythroid progenitors, and T helper type 1 cells were significantly higher in EoE-PPI-TSnr. There was no significant difference in microbiome diversity. The relative abundance of Fusobacterium sp. and Acinetobacter sp. notably differed in EoE-PPI-TSnr and correlated with the key pathways. CONCLUSION Our results provide critical insights into the molecular, cellular, and microbial factors associated with the lack of response to PPI and TS combination therapy in children with EoE. This study advances our understanding of the pathobiology of EoE while guiding personalized treatment strategies.

J Pharm Sci 2024:S0022-3549(24)00423-4. [PMID: 39326843 DOI: 10.1016/j.xphs.2024.09.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 09/11/2024] [Accepted: 09/11/2024] [Indexed: 09/28/2024]
Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus that is immune/antigen-mediated and often requires targeted treatment. In clinical practice, an oral viscous budesonide suspension prepared by adding sucralose to a budesonide suspension for inhalation (Pulmicort®) is used to treat adult EoE and enhance retention in the esophageal mucosa. Inspired by this off-label drug use, oral viscous budesonide solutions (OVBSs) were developed in this study, and their capacities for adhesion, permeation, and stability were explored. Given the insolubility of budesonide as a BCS II drug, we first evaluated its equilibrium solubility and found that Transcutol® HP was an excellent choice for creating an OVBS at a concentration of 0.2 mg/g. The rheological properties of the OVBSs were evaluated with a rheometer, and shear-thinning, which aids in swallowing, was observed. The addition of hydroxyethyl cellulose (HEC) increased the adhesion strength of the preparation, which was associated with the hydration and thickening mechanism. This result was confirmed in a dynamic gelation study and in vitro elution experiment conducted with porcine esophagus tissue. Furthermore, the permeabilities of the OVBSs in the porcine esophagus were evaluated with a Franz diffusion cell device. >80 % of the budesonide was released after 24 h, and the release profile was similar to that of the solution. To explore the storage conditions of OVBSs, critical factors such as pH, content, and impurities were determined. It was found that OVBSs exhibited different behaviors at different pH values and temperatures. Notably, the OVBSs containing 1.7 % HEC could be stored for >6 months at a temperature of 5 °C ± 3 °C and a pH of 4.5 without significant degradation. Overall, this study demonstrated that OVBSs have the potential to adhere to the esophageal mucosa, permeate the tissue, and remain stable during storage. Moreover, OVBSs exhibit a distinct advantage over traditional converted inhalation-to-oral budesonide therapies by enabling flexible dose adjustment in clinical applications, thereby potentially minimizing systemic side effects commonly associated with oral glucocorticoid administration.

Abstract
Eosinophilic esophagitis (EoE) is a chronic Th2-mediated inflammatory disease of the esophagus driven by dietary or inhalant allergens which if left untreated, leads to fibrosis and poor esophageal function. Although the inflammation in the esophagus is dominated by eosinophils, there are also elevated levels of T and B cells. Blood samples from ten patients with EoE before and after treatment with orodispersible budesonide and 10 healthy controls were compared using cytometry by time-of-flight. An antibody panel was designed that covers the major immunological cell populations with a particular focus on eosinophils. The data was analyzed with multivariate methods and cluster analysis. Correlation analysis was done between immune markers and endoscopic, histological, and symptomatologic assessments. Our analysis revealed that patients with EoE had lower levels of effector memory T cells after treatment with orodispersible budesonide to the same level as healthy subjects. In addition, more suppressive eosinophils were present in the circulation of EoE patients before treatment and more immature eosinophils were present after treatment. Furthermore, levels of galectin-10+ eosinophils correlated with histological findings in esophageal tissue from EoE patients. In all patients, the peak eosinophils were decreased after treatment with orodispersible budesonide. Intriguingly, 90% of the patients had remission in the histological assessment and 50% improved in the endoscopic assessment. This study reports a detailed immune profile in patients with EoE before and after treatment with orodispersible budesonide and it is a step toward finding blood-based immune parameters that could be useful to monitor response to treatment.

Prokopienko AJ, Wang J, Yajnik V, Baratta M, Desai NK, Richmond CA, Suri A. Effect of Food on the Pharmacokinetics, Safety, and Tolerability of Budesonide Oral Suspension in Healthy Adult Participants: A Randomized Phase 1 Study. J Clin Pharmacol 2024. [PMID: 39263900 DOI: 10.1002/jcph.6131] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Accepted: 08/22/2024] [Indexed: 09/13/2024]
Abstract
Budesonide oral suspension (BOS) is a swallowed corticosteroid indicated for 12-week therapy in eosinophilic esophagitis with minimal systemic exposure following administration. We aimed to assess the relative bioavailability of a single dose of BOS administered under fasting and fed (high-fat/high-calorie meal) conditions. Healthy adult volunteers (N = 20) were enrolled in an open-label, single-center, crossover study and were randomized (1:1) to receive a single oral dose of BOS 2.0 mg under fasting or fed conditions, with a 48-h washout period before crossover to the alternative conditions. Serial plasma samples were collected before and up to 24 h after dosing. Pharmacokinetic (PK) parameters were calculated from plasma budesonide concentration-time profiles by noncompartmental analysis. The mean peak budesonide concentration (Cmax) was ∼13% lower under fed than under fasting conditions (604.1 vs 692.9 pg/mL). Areas under the concentration-time curves from dosing to the last measurable budesonide concentration and from dosing to infinity were ∼26% higher and ∼27% higher under fed than fasting conditions (3529 vs 2811 pg h/mL and 3892 vs 3075 pg h/mL, respectively). The median time to peak plasma budesonide concentration was significantly longer (∼1 h) under fed than fasting conditions (2.516 vs 1.286 h, P < .001). Safety and tolerability were also assessed throughout the study; all adverse events were mild or moderate in severity. Despite slight differences in budesonide PK parameters between fed and fasting conditions, the effect of food on systemic exposure to budesonide (BOS formulation) is not expected to be clinically meaningful.

Abstract
BACKGROUND Eosinophilic Esophagitis (EoE) is a chronic inflammatory condition of the esophagus triggered by food and aeroallergens. There is a need for noninvasive biomarkers that reliably detect EoE in patients with cardinal symptoms and predict treatment response to reduce endoscopic evaluations. STUDY Nonasthmatic patients 18 years or above with suspected or diagnosed EoE, gastroesophageal reflux disease (GERD), and control individuals with indication for endoscopy were enrolled prospectively between November 2020 and May 2022. Participants underwent body plethysmography with fractionated exhaled nitric oxide (FeNO) level measurement. Besides, serum and fecal biomarkers were measured by ELISA. A follow-up examination was scheduled after treatment initiation in patients with active EoE. RESULTS The median FeNO level in active EoE (20 ppb) was higher compared with GERD (15 ppb, P=0.038) and control individuals (14 ppb, P=0.046). Median FeNO did not significantly differ in EoE patients who underwent follow-up assessment after treatment response (20 ppb vs. 18 ppb, P=0.771). Serum EDN, ECP, and the absolute eosinophil blood count (AEC) were elevated in active EoE compared with control individuals but not compared with GERD except for AEC. Serum EDN, ECP and AEC decreased in EoE in remission at follow-up assessment. None of the fecal biomarkers was elevated in active EoE or during treatment. CONCLUSIONS Assessment of FeNO may have diagnostic value in differentiating patients with active EoE from non-EoE patients but is not a suitable marker for monitoring disease activity. Serum EDN, ECP, TARC, and AEC levels are emerging as potential candidates for monitoring disease activity in EoE.

Abstract
Eosinophilic Esophagitis is a widely-recognized immune-mediated esophagus disease with distinct clinical and histopathological features, exhibiting an increased global incidence. Therapeutic options encompass either dietary measures or pharmacological approaches, including proton pump inhibitors and topical corticosteroids. The use of monoclonal antibodies is currently under comprehensive evaluation, with a plethora of ongoing clinical trials designed to determine their clinical efficacy. The present case report demonstrates an exceptional case of refractory Eosinophilic Esophagitis, unresponsive to conventional treatment, achieving both clinical and histopathological remission subsequent to initiation of benralizumab treatment. Concurrently, our case underscores the necessity for continued research in the field of monoclonal antibodies for their use as a future treatment approach against Eosinophilic Esophagitis.

Abstract
Human sialic acid-binding immunoglobulin-like lectins (Siglecs) are expressed on subsets of immune cells. Siglec-8 is an immune inhibitory Siglec on eosinophils and mast cells, which are effectors in allergic disorders including eosinophilic esophagitis. Inhibition occurs when Siglec-8 is crosslinked by multivalent Siglec ligands in target tissues. Previously we discovered a high-affinity Siglec-8 sialoglycan ligand on human airways composed of terminally sialylated keratan sulfate chains carried on a single protein, DMBT1. Here we extend that approach to another allergic inflammatory target tissue, human esophagus. Lectin overlay histochemistry revealed that Siglec-8 ligands are expressed predominantly by esophageal submucosal glands, and are densely packed in submucosal ducts leading to the lumen. Expression is tissue-specific; esophageal glands express Siglec-8 ligand whereas nearby gastric glands do not. Extraction and resolution by gel electrophoresis revealed a single predominant human esophageal Siglec-8 ligand migrating at >2 MDa. Purification by size exclusion and affinity chromatography, followed by proteomic mass spectrometry, revealed the protein carrier to be MUC5B. Whereas all human esophageal submucosal cells express MUC5B, only a portion convert it to Siglec-8 ligand by adding terminally sialylated keratan sulfate chains. We refer to this as MUC5B S8L. Material from the esophageal lumen of live subjects revealed MUC5B S8L species ranging from ~1-4 MDa. We conclude that MUC5B in the human esophagus is a protein canvas on which Siglec-8 binding sialylated keratan sulfate chains are post-translationally added. These data expand understanding of Siglec-8 ligands and may help us understand their roles in allergic immune regulation.

Abstract
Eotaxin-3 is a key chemokine with a relevant role in eosinophilic esophagitis, a rare chronic immune/antigen-mediated inflammatory disorder. Eotaxin-3 is a potent activator of eosinophil emergence and migration, which may lead to allergic airway inflammation. We investigated, using bioinformatics tools, the protein structure and the possible effects of the known variations reported in public databases. Following a procedure already established, we created a 3D model of the whole protein and modeled the structure of 105 protein variants due to known point mutations. The effects of the amino acid substitution at the level of impact on protein structure, stability, and possibly function were detected by the bioinformatics procedure and described in detail. A web application was implemented to browse the results of the analysis and visualize the 3D models, with the opportunity of downloading the models and analyzing them using their own software. Among 105 amino acid substitutions investigated, the study evidenced in 44 cases at least one change in any of the investigated structural parameters. Other six variations are also relevant, although a structural effect was not detected by our analysis, because they affected amino acids highly conserved, which suggests a possible function role. All these variations should be the object of particular attention, as they may induce a loss of functionality in the protein.

Abstract
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.

Abstract
BACKGROUND Recently, we have identified a dysregulated protein signature in the esophageal epithelium of eosinophilic esophagitis (EoE) patients including proteins associated with inflammation and epithelial barrier function; however, the effect of proton pump inhibitor (PPI) treatment on this signature is unknown. Herein, we used a proteomic approach to investigate: (1) whether PPI treatment alters the esophageal epithelium protein profile observed in EoE patients and (2) whether the protein signature at baseline predicts PPI response. METHODS We evaluated the protein signature of esophageal biopsies using a cohort of adult EoE (n = 25) patients and healthy controls (C) (n = 10). In EoE patients, esophageal biopsies were taken before (pre) and after (post) an 8-week PPI treatment, determining the histologic response. Eosinophil count PostPPI was used to classify the patients: ≥15 eosinophils/hpf as non-responders (non-responder) and < 15 eosinophils/hpf as responders (R). Protein signature was determined and differentially accumulated proteins were characterized to identify altered biological processes and signaling pathways. RESULTS Comparative analysis of differentially accumulated proteins between groups revealed common signatures between three groups of patients with inflammation (responder-PrePPI, non-responder-PrePPI, and non-responder-PostPPI) and without inflammation (controls and responder-PostPPI). PPI therapy almost reversed the EoE specific esophageal protein signature, which is enriched in pathways associated with inflammation and epithelial barrier function, in responder-PostPPI. Furthermore, we identified a set of candidate proteins to differentiate responder-PrePPI and non-responder-PrePPI EoE patients before treatment. CONCLUSION These findings provide evidence that PPI therapy reverses the alterations in esophageal inflammatory and epithelial proteins characterizing EoE, thereby providing new insights into the mechanism of PPI clinical response. Interestingly, our results also suggest that PPI response could be predicted at baseline in EoE.

Abstract
Gastroesophageal reflux (GER) and eosinophilic esophagitis (EoE) are the most common inflammatory causes of pediatric dysphagia, but several other less prevalent conditions should be considered. These conditions can affect one or several aspects of the swallowing process. In some inflammatory conditions dysphagia may be an early symptom. Esophagoscopy and instrumental swallow studies are often needed to determine the underlying diagnosis and best treatment plan. In some inflammatory conditions dysphagia can portend a worse outcome and need for more aggressive treatment of the underlying condition. Consultations with speech language pathology, gastroenterology, dietetics, allergy/immunology and/or rheumatology are often needed to optimize management.

Abstract
Background Celiac disease (CeD) is associated with several immune-mediated disorders, but it is unclear whether it is associated with eosinophilic esophagitis (EoE). Objective We sought to examine the risk of EoE in patients with biopsy-verified CeD compared with matched controls and siblings. Methods Using nationwide population-based histopathology data, we identified 27,338 patients with CeD diagnosed in the period 2002 to 2017 in Sweden. Patients with CeD were age- and sex-matched with up to 5 reference individuals (n = 134,987) from the general population. Cox Regression was used to estimate hazard ratios (HRs) for developing biopsy-verified EoE. In a secondary analysis, we used unaffected siblings of patients with CeD as comparators to adjust for intrafamilial confounding. Results The median age at CeD diagnosis was 27 years, and 63.3% were female patients. During a median follow-up of 8.1 years, 17 patients with CeD and 13 matched reference individuals were diagnosed with EoE. This corresponded to incidence rates of 0.08 versus 0.01 per 1000 person-years, respectively, and an adjusted HR for EoE of 6.65 (95% CI, 3.26-13.81). Compared with their siblings without CeD, patients with CeD were however at a no increased risk of EoE (HR, 1.39; 95% CI, 0.55-3.51). Conclusions In this study, individuals with CeD were at a 6.6-fold increased risk of later EoE compared with the general population. This association might be explained by an altered health-seeking behavior or through shared genetic or early environmental factors because the excess risk disappeared in sibling analyses.

Abstract
Immune-mediated gastrointestinal (GI) diseases, including achalasia, celiac disease, and inflammatory bowel diseases, pose significant challenges in diagnosis and management due to their complex etiology and diverse clinical manifestations. While genetic predispositions and environmental factors have been extensively studied in the context of these conditions, the role of viral infections and virome dysbiosis remains a subject of growing interest. This review aims to elucidate the involvement of viral infections in the pathogenesis of immune-mediated GI diseases, focusing on achalasia and celiac disease, as well as the virome dysbiosis in IBD. Recent evidence suggests that viral pathogens, ranging from common respiratory viruses to enteroviruses and herpesviruses, may trigger or exacerbate achalasia and celiac disease by disrupting immune homeostasis in the GI tract. Furthermore, alterations in the microbiota and, specifically, in the virome composition and viral-host interactions have been implicated in perpetuating chronic intestinal inflammation in IBD. By synthesizing current knowledge on viral contributions to immune-mediated GI diseases, this review aims to provide insights into the complex interplay between viral infections, host genetics, and virome dysbiosis, shedding light on novel therapeutic strategies aimed at mitigating the burden of these debilitating conditions on patients' health and quality of life.

Abstract
Eosinophilic esophagitis is a chronic inflammatory disorder of the esophagus. Over the past 25 yr, great strides have been made toward understanding its pathogenesis, in part due to studies in several types of animal models. The vast majority of these models have been characterized in mice. In this review, we summarize the histopathological features of eosinophilic esophagitis recapitulated by these animal models, as well as discuss their strengths and weaknesses.

Abstract
Quality indicators (QIs) are standardized metrics that can be used to quantify health care delivery and identify important areas for practice improvement. Nine QIs pertaining to the diagnosis and management of eosinophilic esophagitis (EoE) were recently established. We therefore aimed to identify existing gaps in care using these QIs. This is a retrospective, multicenter study utilizing recently established EoE QIs to evaluate practice patterns among adult gastroenterologists in the diagnosis and management of EoE. Three patient cohorts of 30 patients each presenting with dysphagia, food impaction, and new diagnosis of EoE, respectively, were obtained, yielding 120 patients per site to assess for every QI. Summary statistics were reported across two main themes: diagnosis and management. Subsequent analysis of gaps in care was then performed. The domain of diagnosis of EoE (QI 1 and 2) had the most notable gap in care with only 55% of the presenting patients undergoing appropriate evaluation for EoE. The domain of management of EoE had overall higher QI fulfillment-however it also contained significant intra-category variation in care. Notably, while 79% of patients had clinical follow-up within 1 year from remission, only 54% underwent surveillance endoscopy within 2 years of remission. In contrast, 100% of patients with symptomatic strictures independent of histologic response underwent endoscopic dilation (QI 4). Management approaches for EoE are evolving and variation in care delivery exists. We identified significant gaps in both diagnosis of EoE especially amongst patients presenting with index food impaction and long term management of EoE, when retrospectively evaluating care patterns using newly established QIs. This is the first study of its kind to utilize these previously established QIs to objectively identify care gaps that exist in EoE amongst several institutions. These findings also highlight the importance of QIs and standardization of management of complex chronic diseases like EoE to help bridge these gaps and provide a framework to measure adherence to these best practices.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is increasing in prevalence but there is a lack of population-based studies. We sought to determine the prevalence, demographics, and associated atopic diseases in the Veterans Affairs (VA) population. METHODS A nationwide analysis of data from the VA patient population was done using a Veterans Health Administration database. EoE was identified using ICD9 (530.13) and ICD10 (K20.0) codes from October 2008 to June 2020. Demographic data, smoking status, BMI, treatment, and ICD codes for atopic diagnoses were collected. Two sample proportion z-tests, Chi-square tests, two-sample t tests, and one-way ANOVA were used to assess associations across demographic categories. RESULTS We identified a total of 11,775 patients with an EoE diagnosis: 91% male, 83% White, 8.6% Black, and 5% were of Hispanic ethnicity. The prevalence of EoE increased over time. At diagnosis, the mean age was 48.5 years overall, 51.6 years for Black patients, 45.3 years for Hispanic patients, and 48.2 years for Whites. Dysphagia was the most common symptom overall, but a higher percentage of Blacks and females were found to report chest pain (p < 0.0001, h = 0.32). With the exception of urticaria and atopic dermatitis, both Blacks and Hispanics had a higher incidence of atopic conditions compared to other races and ethnicities (p < 0.0001). CONCLUSION While EoE is seen primarily in White males, our study shows that a notable percentage of patients were Black or Hispanic, suggesting that EoE should be considered in non-white patients. The later age of diagnosis in this group could represent a lack of awareness about EoE among non-white patients. More research is needed to study these associations.

Abstract
OBJECTIVE To analyse the histopathological features of eosinophilic sialodochitis by using terminal duct biopsy. METHODS Sixty-five patients with suspected eosinophilic sialodochitis and four with chronic obstructive sialadenitis were prospectively enrolled. Clinical features, laboratory tests and sialograms were comparatively analysed. Terminal duct biopsy of the parotid or submandibular glands was performed concomitantly with endoscopy-assisted duct dilatation to determine the histopathological features of eosinophilic sialodochitis. RESULTS Based on eosinophil quantification, the samples of suspected patients were scored as 'definite', 'highly suspected' and 'negative' in 26 (40%), 15 (23.1%) and 24 (36.9%) cases, respectively. Gland types and peripheral blood eosinophil counts were significantly different among these three groups. The proportions of itching glands, mucus plug exudations and elevated immunoglobulin E levels were higher in the 'definite' group than in the other two groups; however, the intergroup differences were insignificant. The primary pathological features of eosinophilic sialodochitis were abundant eosinophils and lymphocytes infiltrated around the duct, degranulation of eosinophils, extensive fibrosis and scattered mastocytes. Periductal eosinophils were not found in cases of chronic obstructive sialadenitis. CONCLUSION Our findings suggest that terminal duct biopsy is safe and valuable for the pathological confirmation of eosinophilic sialodochitis, and can be used simultaneously with endoscopy-assisted duct dilatation.

Abstract
BACKGROUND AND AIMS Monoclonal antibodies (MAbs) have clinical benefits for treating several atopic diseases. However, consensus on its use for eosinophilic esophagitis (EoE) is lacking. The present meta-analysis aimed to compare the efficacy and safety of MAbs versus placebo for treating EoE. METHODS We searched PubMed, Embase, and Cochrane Library for randomized controlled trials (RCTs). The primary outcomes were changes in peak esophageal eosinophils count/high power field (HPF) and mean esophageal eosinophils count/HPF. The secondary outcomes were changes in the EoE-Histology Scoring System (EoE-HSS), Endoscopic Reference Score (EREFS), dysphagia score, and adverse events (AEs). We compared binary outcomes using risk ratio (RR) and continuous outcomes using mean difference (MD) or standardized mean difference (SMD), with 95% confidence interval (CI). Considering the diversity of mechanistic properties of MAbs, a pre-specified subgroup analysis by MAb mechanism of action was performed for all outcomes, provided that at least two studies were in each subgroup. Heterogeneity was assessed using Cochran's Q test and I2 statistics. RESULTS 6 RCTs were included (533 patients). Compared to placebo, MAbs led to a significant reduction in peak esophageal eosinophils count/HPF (MD -0.78; CI 95% -0.87, -0.6801) and mean esophageal eosinophils count/HPF (SMD -0.79; CI 95% -1.5, -0.08). Moreover, MAbs significantly reduced EoE-HSS scores (grade score: SMD -9.31; 95% CI -13.95, -4.6701; stage score: SMD -10.18; 95% CI -15.06, -5.31), EREFS (SMD -5.95; CI 95% -9.19, -2.71) and dysphagia score (SMD -1.79; CI 95% -3.36, -0.23) without increasing AEs compared to placebo. Among those MAbs whose mechanism of action includes the blockage of the receptor for IL-13 (Dupilumab, QAX576, and RPC4046), the scores of EoE-HSS grade, EoE-HSS stage, EREFS, and dysphagia were significantly reduced, and they presented a similar risk of overall and serious AEs compared to placebo. CONCLUSION MAbs seem effective and safe in reducing esophageal eosinophil infiltrate, EoE-HSS score, EREFS score, and dysphagia symptoms in patients with EoE. However, further evidence is needed to establish its place in EoE management.

Abstract
BACKGROUND Dupilumab is a human monoclonal antibody that blocks interleukin-4 and interleukin-13 pathways and has shown efficacy in five different atopic diseases marked by type 2 inflammation, including eosinophilic esophagitis in adults and adolescents. METHODS In this phase 3 trial, we randomly assigned, in a 2:2:1:1 ratio, patients 1 to 11 years of age with active eosinophilic esophagitis who had had no response to proton-pump inhibitors to 16 weeks of a higher-exposure or lower-exposure subcutaneous dupilumab regimen or to placebo (two groups) (Part A). At the end of Part A, eligible patients in each dupilumab group continued the same regimen and those in the placebo groups were assigned to higher-exposure or lower-exposure dupilumab for 36 weeks (Part B). At each level of exposure, dupilumab was administered in one of four doses tiered according to baseline body weight. The primary end point was histologic remission (peak esophageal intraepithelial eosinophil count, ≤6 per high-power field) at week 16. Key secondary end points were tested hierarchically. RESULTS In Part A, histologic remission occurred in 25 of the 37 patients (68%) in the higher-exposure group, in 18 of the 31 patients (58%) in the lower-exposure group, and in 1 of the 34 patients (3%) in the placebo group (difference between the higher-exposure regimen and placebo, 65 percentage points [95% confidence interval {CI}, 48 to 81; P<0.001]; difference between the lower-exposure regimen and placebo, 55 percentage points [95% CI, 37 to 73; P<0.001]). The higher-exposure dupilumab regimen led to significant improvements in histologic, endoscopic, and transcriptomic measures as compared with placebo. The improvements in histologic, endoscopic, and transcriptomic measures between baseline and week 52 in all the patients were generally similar to the improvements between baseline and week 16 in the patients who received dupilumab in Part A. In Part A, the incidence of coronavirus disease 2019, nausea, injection-site pain, and headache was at least 10 percentage points higher among the patients who received dupilumab (at either dose) than among those who received placebo. Serious adverse events were reported in 3 patients who received dupilumab during Part A and in 6 patients overall during Part B. CONCLUSIONS Dupilumab resulted in histologic remission in a significantly higher percentage of children with eosinophilic esophagitis than placebo. The higher-exposure dupilumab regimen also led to improvements in measures of key secondary end points as compared with placebo.

Abstract
BACKGROUND Benralizumab is an eosinophil-depleting anti-interleukin-5 receptor α monoclonal antibody. The efficacy and safety of benralizumab in patients with eosinophilic esophagitis are unclear. METHODS In a phase 3, multicenter, double-blind, randomized, placebo-controlled trial, we assigned patients 12 to 65 years of age with symptomatic and histologically active eosinophilic esophagitis in a 1:1 ratio to receive subcutaneous benralizumab (30 mg) or placebo every 4 weeks. The two primary efficacy end points were histologic response (≤6 eosinophils per high-power field) and the change from baseline in the score on the Dysphagia Symptom Questionnaire (DSQ; range, 0 to 84, with higher scores indicating more frequent or severe dysphagia) at week 24. RESULTS A total of 211 patients underwent randomization: 104 were assigned to receive benralizumab, and 107 were assigned to receive placebo. At week 24, more patients had a histologic response with benralizumab than with placebo (87.4% vs. 6.5%; difference, 80.8 percentage points; 95% confidence interval [CI], 72.9 to 88.8; P<0.001). However, the change from baseline in the DSQ score did not differ significantly between the two groups (difference in least-squares means, 3.0 points; 95% CI, -1.4 to 7.4; P = 0.18). There was no substantial between-group difference in the change from baseline in the Eosinophilic Esophagitis Endoscopic Reference Score, which reflects endoscopic abnormalities. Adverse events were reported in 64.1% of the patients in the benralizumab group and in 61.7% of those in the placebo group. No patients discontinued the trial because of adverse events. CONCLUSIONS In this trial involving patients 12 to 65 years of age with eosinophilic esophagitis, a histologic response (≤6 eosinophils per high-power field) occurred in significantly more patients in the benralizumab group than in the placebo group. However, treatment with benralizumab did not result in fewer or less severe dysphagia symptoms than placebo. (Funded by AstraZeneca; MESSINA ClinicalTrials.gov number, NCT04543409.).

Caminati M, Senna G, Maule M, Di Sabatino A, Rossi CM. Diagnosis, management and therapeutic options for eosinophilic esophagitis. Curr Opin Allergy Clin Immunol 2024; 24:122-128.

Abstract
PURPOSE OF REVIEW Eosinophilic esophagitis is a chronic and commonly evolving condition leading to relevant and potentially irreversible burden in terms of tissue damage and related functional impairment, thus significantly impacting on quality of life. The aim of the present review is to summarize the recent advances in terms of diagnostic work-up and pharmacological and nonpharmacological management of the disease, under the broader perspective of type 2 inflammation. RECENT FINDINGS Two major novelties have prompted an innovative approach to EoE. In terms of diagnosis, it has been proposed to dissect the disease heterogeneity in three endotypes, independent from tissue eosinophil number: EoEe1, characterized by normal appearing oesophagus; EoEe2, associated with type 2 inflammation and steroid-refractoriness; EoEe3, whose features include adult onset, a more fibro-stenotic aspect and loss of epithelial gene expression. Concerning treatment, two recently licensed drugs for EoE, oro-dispersible budesonide and dupilumab represent the first treatment options specifically developed for EoE and addressing EoE-related peculiar pathobiological features. SUMMARY In the era of precision medicine, managing EoE according to a phenotype-driven approach might be helpful in defining the best treatment options in the different disease forms or stages. In addition, exploring the coexistence or the previous occurrence of other type 2 conditions may suggest the opportunity to specifically target type 2 inflammation through biologic therapy. The complex EoE pathobiology combining inflammatory and functional features, both at organ and systemic level, requires a multidimensional approach relying on the strict integration of gastroenterologists and allergist-immunologists.

Abstract
Eosinophilic esophagitis (EoE) is a chronic type 2-mediated inflammatory disease of the esophagus that represents the most common eosinophilic gastrointestinal disease. Experts in the field of EoE across Italy (i.e., EoETALY Consensus Group) including gastroenterologists, endoscopists, allergologists/immunologists, and paediatricians conducted a Delphi process to develop updated consensus statements for the management of patients with EoE and update the previous position paper of the Italian Society of Gastroenterology (SIGE) in light of recent evidence. Grading of the strength and quality of the evidence of the recommendations was performed using accepted GRADE criteria. The guideline is divided in two documents: Part 1 includes three chapters, namely 1) definition, epidemiology, and pathogenesis; 2) clinical presentation and natural history, and 3) diagnosis, while Part 2 includes two chapters: 4) treatment and 5) monitoring and follow-up. This document has received the endorsement of three Italian national societies including the SIGE, the Italian Society of Neurogastroenterology and Motility (SINGEM), and the Italian Society of Allergology, Asthma, and Clinical Immunology (SIAAIC). With regards to patients' involvement, these guidelines involved the contribution of members of ESEO Italia, the Italian Association of Families Against EoE.

Abstract
Celiac disease (CeD) is a chronic immune-mediated condition triggered by gluten consumption in genetically predisposed individuals. Approximately 1% of the general population is affected by the disorder. Disease presentation is heterogeneous and, despite growing awareness among physicians and the public, it continues to be underestimated. The most effective strategy for identifying undiagnosed CeD is proactive case finding through serologic testing in high-risk groups. We reviewed the most recent evidence on the association between CeD and more than 20 conditions. In light of this review, CeD screening is recommended in individuals with (1) autoimmune disease and accompanying symptoms suggestive of CeD; (2) diseases that may mimic CeD (eg, irritable bowel syndrome [IBS], inflammatory bowel disease [IBD], and microscopic colitis); and (3) among patients with conditions with a high CeD prevalence: first-degree relatives, idiopathic pancreatitis, unexplained liver enzyme abnormalities, autoimmune hepatitis, primary biliary cholangitis, hyposplenism or functional asplenia with severe bacterial infection, type 1 diabetes mellitus, Hashimoto's thyroiditis and Graves' disease, Sjögren's syndrome, dermatitis herpetiformis, recurrent aphthous syndrome and enamel defects, unexplained ataxia, peripheral neuropathy, delayed menarche or premature menopause, Down syndrome, Turner syndrome, Williams syndrome, chronic fatigue syndrome, IgA nephropathy, and IgA deficiency. CeD serology should be the initial step in the screening process. However, for patients with any of the aforementioned disorders who are undergoing upper endoscopy, biopsies should be performed to rule out CeD.

Abstract
OBJECTIVE To develop evidence-based guidance for topical steroid use in paediatric eosinophilic oesophagitis (pEoE) in the UK for both induction and maintenance treatment. METHODS A systematic literature review using Cochrane guidance was carried out by the British Society of Paediatric Gastroenterology, Hepatology and Nutrition (BSPGHAN) Eosinophilic Oesophagitis (EoE) Working Group (WG) and research leads to determine the evidence base for preparation, dosing and duration of use of swallowed topical steroid (STS) formulations in EoE. Seven themes relating to pEoE were reviewed by the WG, alongside the Cochrane review this formed the evidence base for consensus recommendations for pEoE in the UK. We provide an overview of practical considerations including treatment regimen and dosing. Oral viscous budesonide (OVB) and, if agreed by local regulatory committees, orodispersible budesonide (budesonide 1 mg tablets) were selected for ease of use and with most improvement in histology. A practical 'how to prepare and use' OVB appendix is included. Side effects identified included candidiasis and adrenal gland suppression. The use of oral systemic steroids in strictures is discussed briefly. RESULTS 2638 citations were identified and 18 randomised controlled trials were included. Evidence exists for the use of STS for induction and maintenance therapy in EoE, especially regarding histological improvement. Using the Appraisal of Guidelines, Research and Evaluation criteria, dosing of steroids by age (0.5 mg two times per day <10 years and 1 mg two times per day ≥10 years) for induction of at least 3 months was suggested based on evidence and practical consideration. Once histological remission is achieved, maintenance dosing of steroids appears to reduce the frequency and severity of relapse, as such a maintenance weaning regimen is proposed. CONCLUSION A practical, evidence-based flow chart and guidance recommendations with consensus from the EoE WG and education and research representatives of BSPGHAN were developed with detailed practical considerations for use in the UK.

Abstract
BACKGROUND Eosinophilic oesophagitis (EOE) is a known cause of food bolus obstruction (FBO) with rising incidence and prevalence. AIMS To assess the rates of EOE in adult cases presenting with an FBO via prospective biopsy collection during index endoscopy. METHODS Oesophageal FBO cases requiring gastroscopy between February 2014 and January 2021 at a single institution with a unified policy to perform biopsies on FBO cases were analysed using medical records, endoscopy and histology. Statistical analysis was undertaken to compare those with and without EOE as their final diagnosis, including the timing of oesophageal biopsy and the season that cases presented. RESULTS One hundred ninety FBO presentations were analysed, 15 patients presented twice and one patient presented four times within the 7-year study period. Men represented 72% of cases. A total of 78% of cases had biopsies collected at an index or scheduled follow-up endoscopy. EOE was the cause of the FBO in 28% (53/190) of presentations. FBO secondary to EOE was more likely to occur in the spring and summer months (Australian September to March), with 39% (19 of 49) of cases presenting in spring attributable to EOE. CONCLUSION EOE affects a significant proportion of patients presenting with FBO (28%); a high biopsy rate of 78% in FBO cases provides an opportunity for prompt diagnosis and treatment.

Abstract
The diagnosis of eosinophilic esophagitis (EoE) is based on clinical symptoms of esophageal dysfunction and eosinophil predominant esophageal inflammation. Clinical symptoms in children with EoE vary based on age and may be nonspecific. EoE has a male predominance with the majority having comorbid atopic disorders. At present, treatment options include medications (proton pump inhibition, swallowed topical steroids), dietary therapy or biologic therapy (dupilumab, approved for those ≥12 years of age). Outside of EoE in the context of oral immunotherapy, EoE is typically chronic requiring lifelong therapy. Long-term complications including feeding difficulties, malnutrition, and fibrostenotic disease.

Abstract
Eosinophilic esophagitis (EoE) is an immune/antigen-mediated disease with an increasing incidence over the last decade. Clinicopathological remission can be achieved through different treatment options but often requires chronic therapy. To our knowledge, this is the first report of EoE wherein the patient (a 54-year-old man) achieved histological remission after allogeneic hematopoietic stem cell transplantation (HSCT) for acute myelogenous leukemia. Overall, despite the success of EoE treatment in this case, further studies are needed to establish allogeneic HSCT as a curative option for EoE.

Abstract
Background Eosinophilic esophagitis (EoE) and inflammatory bowel diseases (IBDs), including Crohn's disease (CD) and ulcerative colitis (UC), are immune-mediated gastrointestinal diseases with overlapped pathogenesis and are sometimes concurrently diagnosed, but their causal relationship remains unclear. We investigated the causal relationship between EoE and IBD and its subtypes via a two-sample bidirectional Mendelian randomization (MR) approach. Methods MR analyses were performed using summary data of a genome-wide association study (GWAS) on individuals of European ancestry. Independent single-nucleotide polymorphisms correlated with EoE (from a GWAS meta-analysis containing 1,930 cases and 13,634 controls) and IBD (from FinnGen GWASs containing 9,083 IBD, 2,033 CD, and 5,931 UC cases, and GWASs of IBD genetic consortium containing 12,882 IBD, 6,968 UC, and 5,956 CD cases) were selected as instruments. We applied the inverse variance weighted (IVW) method as the primary analysis followed by several sensitivity analyses. For the forward MR study, estimates from IVW methods were subsequently meta-analyzed using a random-effect model. Results Our results suggested a causal effect of EoE on IBD [pooled odds ratio (OR), 1.07; 95% confidence interval (CI), 1.02-1.13] and EoE on UC (pooled OR, 1.09, 95% CI, 1.04-1.14). No causal link between EoE and CD was observed (pooled OR, 1.05; 95% CI, 0.96-1.16). The reverse MR analyses revealed no causal effect of IBD (and its subtypes) on EoE. Sensitivity analyses confirmed the robustness of primary results. Conclusions Our findings provided evidence of a suggestive causal effect of EoE on IBD (specifically on UC) in the European population. Increased awareness of concurrent or subsequent IBD in patients with EoE is called for. Still, the present evidence is not adequate enough and ought to be validated by further investigations.

Abstract
Eosinophilic Gastrointestinal Disorders (EGIDs) are a group of conditions characterized by abnormal eosinophil accumulation in the gastrointestinal tract. Among these EGIDs, Eosinophilic Esophagitis (EoE) is the most well documented, while less is known about Eosinophilic Gastritis (EoG), Eosinophilic Enteritis (EoN), and Eosinophilic Colitis (EoC). The role of endoscopy in EGIDs is pivotal, with applications in diagnosis, disease monitoring, and therapeutic intervention. In EoE, the endoscopic reference score (EREFS) has been shown to be accurate in raising diagnostic suspicion and effective in monitoring therapeutic responses. Additionally, endoscopic dilation is the first-line treatment for esophageal strictures. For EoG and EoN, while the literature is more limited, common endoscopic findings include erythema, nodules, and ulcerations. Histology remains the gold standard for diagnosing EGIDs, as it quantifies eosinophilic infiltration. In recent years, there have been significant advancements in the histological understanding of EoE, leading to the development of diagnostic scores and the identification of specific microscopic features associated with the disease. However, for EoG, EoN, and EoC, precise eosinophil count thresholds for diagnosis have not yet been established. This review aims to elucidate the role of endoscopy and histology in the diagnosis and management of the three main EGIDs and to analyze their strengths and limitations, their interconnection, and future research directions.

Abstract
Coordinated cell interactions within the esophagus maintain homeostasis, and disruption can lead to eosinophilic esophagitis (EoE), a chronic inflammatory disease with poorly understood pathogenesis. We profile 421,312 individual cells from the esophageal mucosa of 7 healthy and 15 EoE participants, revealing 60 cell subsets and functional alterations in cell states, compositions, and interactions that highlight previously unclear features of EoE. Active disease displays enrichment of ALOX15+ macrophages, PRDM16+ dendritic cells expressing the EoE risk gene ATP10A, and cycling mast cells, with concomitant reduction of TH17 cells. Ligand-receptor expression uncovers eosinophil recruitment programs, increased fibroblast interactions in disease, and IL-9+IL-4+IL-13+ TH2 and endothelial cells as potential mast cell interactors. Resolution of inflammation-associated signatures includes mast and CD4+ TRM cell contraction and cell type-specific downregulation of eosinophil chemoattractant, growth, and survival factors. These cellular alterations in EoE and remission advance our understanding of eosinophilic inflammation and opportunities for therapeutic intervention.

Abstract
Background: Eosinophilic esophagitis (EoE) is a disease that has been subcategorized into two endoscopic phenotypes: inflammatory and fibrostenotic. Moreover, studies have shown a link between EoE and immunoglobulin G4 (IgG4), a subclass of the immunoglobulin G (IgG) antibody. In this study, we aimed to evaluate the relationship between histologic IgG4 expression and endoscopic phenotypes in patients with EoE. Methods: This case-control study included patients diagnosed with EoE (n = 19) and patients with non-obstructive dysphagia without abnormal findings as controls (NOD; n = 12). The EoE group was further divided into three subgroups based on endoscopic phenotype: inflammatory, fibrostenotic, or combined. Retrospective examination of endoscopic findings and pathological slides was performed to analyze IgG4 staining. Results: Histological analysis revealed a significant difference in IgG4 cell count (15.00 vs. 0.58, p = 0.003) and eosinophil cell count (84.67 vs. 0.08, p < 0.001) between the EoE and NOD groups. Symptom manifestation and blood test results were similar across all three endoscopic EoE phenotypes. However, histological analysis revealed a significant difference in IgG4 cell count between the inflammatory, fibrostenotic, and combined phenotypes (4.13 vs. 17.6 vs. 59.7, p = 0.030). Conclusions: IgG4 expression was higher in EoE patients than in those with NOD, the highest being in the combined phenotype subgroup. These findings emphasize the important role of endoscopic and histological examination in diagnosing EoE and the need for further research in this area.

J Pediatr Gastroenterol Nutr 2024; 78:878-885. [PMID: 38591709 DOI: 10.1002/jpn3.12127] [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: 08/31/2023] [Revised: 12/13/2023] [Accepted: 12/15/2023] [Indexed: 04/10/2024]
Abstract
BACKGROUND Recurrent upper endoscopies are essential for monitoring therapy response and disease activity in patients with eosinophilic esophagitis (EoE), leading to increased costs, procedural complications, and anesthesia exposure. The aim of this study was to examine an office-based model using serial sedation-free blind esophageal epithelial brushing (BEEB) to monitor therapy response through eosinophil-derived neurotoxin (EDN) levels and guide therapy plans in pediatric EoE patients. METHODS EoE patients (≤21 years of age) were enrolled in this prospective study. Subjects were placed on dietary, pharmacologic, or combination therapy with the goal of inducing or maintaining remission. To assess response to sequential interventions, subjects underwent sequential sedation-free BEEBs through nasogastric tubes to measure EDN levels. Based on serial brushings, an individual plan of diet, medications, or a combination of both was created for each subject, and a final endoscopy was then performed to validate the accuracy of the individual plans. RESULTS Twenty-four subjects completed the study. The average peak eosinophil count in patients with active EoE was 58.1 ± 30.8 eosinophils per high-power field and mean EDN level was 165.2 ± 191.3 μg/mL. A total of 42 BEEBs were completed. Individual therapy plans based on sequential BEEB were accurate in 19 out of the 24 patients (79%) and specifically nine out of 10 patients (90%) treated with elimination diets. CONCLUSION This study suggests that office-based sedation-free BEEBs can be used to monitor therapy response and disease activity in pediatric EoE patients.

Abstract
Eosinophilic esophagitis (EoE) is a chronic inflammatory condition characterized by an intense infiltration of eosinophils into the esophageal epithelium. When not adequately controlled, eosinophilic inflammation can lead to changes in components of the extracellular matrix (ECM) of the lamina propria. Particularly, alterations to the collagen fiber matrix can lead to lamina propria fibrosis (LPF), which plays an important role in the fibrostenotic complications of EoE. Current approaches to assess LPF in EoE are prone to inter-observer inconsistencies and provide limited insight into the structural remodeling of the ECM. An objective approach to quantify LPF can eliminate inter-observer inconsistencies and provide novel insights into the fibrotic transformation of the lamina propria in EoE. Second harmonic generation (SHG) microscopy is a powerful modality for objectively quantifying disease associated alterations in ECM collagen structure that is finding increasing use for clinical research. We used SHG with morphometric analysis (SHG-MA) to characterize lamina propria collagen fibers and ECM porosity in esophageal biopsies collected from children with active EoE (n = 11), inactive EoE (n = 11), and non-EoE (n = 11). The collagen fiber width quantified by SHG-MA correlated positively with peak eosinophil count (r = 0.65, p < 0.005) and histopathologist scoring of LPF (r = 0.52, p < 0.005) in the esophageal biopsies. Patients with active EoE had a significant enlargement of ECM pores compared to inactive EoE and non-EoE (p < 0.005), with the mean pore area correlating positively with EoE activity (r = 0.76, p < 0.005) and LPF severity (r = 0.65, p < 0.005). These results indicate that SHG-MA can be utilized to objectively characterize and provide novel insights into lamina propria ECM structural remodeling in children with EoE, which could aid in monitoring disease progression.

Abstract
INTRODUCTION Emerging evidence suggests a high burden of psychosocial comorbidities in patients with eosinophilic esophagitis (EoE), although factors associated with this burden have not been explored. We aimed to increase understanding of the psychosocial burden of EoE and assess factors that are associated with disease burden. METHODS We conducted a cross-sectional study of patients with EoE (n = 87) recruited from a single-center, multidisciplinary pediatric eosinophilic gastrointestinal disorders clinic (2019-2021). Participants (aged 8-18 years) completed validated assessments during routine clinic visit to assess EoE symptoms (Pediatric Eosinophilic Esophagitis Symptom Score version 2.0), quality of life (Pediatric Quality of LIfe- Eosinophilic Esophagitis), anxiety state and trait (State-Trait Anxiety Score for Children), somatization (Child Somatic Symptoms Inventory 24), sleep disordered breathing (Pediatric Sleep Questionnaire) and, in a subset (n = 35), resilience (Connor Davidson Resilience Scale). Clinical and demographic data were collected. RESULTS Participants were at a mean (SD) age of 12.8 (3.1) years, and 26% (n = 23) were female. Shorter disease duration (6-12 months) was associated with higher symptom burden ( P = 0.03), somatization ( P < 0.01), and anxiety (State-Trait Anxiety Score for Children Trait P < 0.01) scores. Participants with neurodevelopmental comorbidities had higher anxiety trait, somatization, sleep disordered breathing, and lower quality of life ( P < 0.01 for all). Symptom burden was significantly associated with increased somatic symptoms (adjusted β [aβ] = 0.34; 95% confidence interval 0.23-0.45) and decreased quality of life (aβ = -0.42; 95% confidence interval -0.59 to -0.25) but not state anxiety, trait anxiety, or disordered sleep breathing. DISCUSSION Pediatric patients with a recent diagnosis of EoE can experience higher EoE symptoms, somatization, and anxiety when compared with those with a longer-standing diagnosis. Patients earlier in their diagnosis and with neurodevelopmental disorders may experience increased somatization and anxiety that may warrant additional support services.

Abstract
Food allergy is a major health concern worldwide, encompassing both immunologic and non-immunologic reactions. This review thoroughly examines the pathophysiology, clinical manifestations, and treatment options for various types of food allergies. Immunologic food allergies, including IgE-mediated reactions such as oral allergy syndrome and systemic anaphylaxis, pose various diagnostic and management challenges. Non-IgE-mediated reactions such as food protein-induced enterocolitis syndrome, dermatitis herpetiformis, and proctocolitis necessitate individualized patient care. In addition, mixed reactions such as eosinophilic esophagitis and atopic dermatitis complicate the clinical picture. Skin prick tests, serum-specific IgE tests, and oral food challenges are all necessary for accurate food allergy diagnosis. The primary therapeutic options are allergen avoidance, epinephrine-based emergency management, and emerging treatments like immunotherapy. Our review emphasizes the importance of multidisciplinary collaboration and ongoing research in improving our understanding and managing food allergies, promising a brighter future for those affected.

Abstract
BACKGROUND Eosinophilic esophagitis (EoE) is a chronic immune mediated inflammatory disorder of the esophagus. It is still unknown why children and adults present differently, and there is little evidence about why it is more common in men than women. OBJECTIVE Our aim was to synthesize published and unpublished esophageal bulk RNA-sequencing (RNA-seq) data to gain novel insights into the pathobiology of EoE and examine the differences in EoE transcriptome by sex and age group. METHODS Esophageal bulk RNA-seq data from 5 published and 2 unpublished studies resulting in 137 subjects (EoE: N = 76; controls: N = 61) were analyzed. For overall analysis, combined RNA-seq data of patients with EoE were compared with those of controls and subgroup analysis was conducted in patients with EoE by age of the patient (children [<18 years] vs adults [≥18 years]) and sex (female vs male). Gene-set enrichment analysis, ingenuity pathway analysis (IPA), cell-type analysis, immunohistochemistry, and T-cell or B-cell receptor analysis were performed. RESULTS Overall analysis identified dysregulation of new genes in EoE compared with controls. IPA revealed that EoE is characterized by a mixed inflammatory response compared with controls. Cell-type analysis showed that cell composition varied with age: children had more mast cells, whereas adults had more macrophages. Finally, gene-set enrichment analysis and IPA revealed pathways that were differentially regulated in adults versus children and male versus female patients with EoE. CONCLUSIONS Using a unique approach to analyze bulk RNA-seq data, we found that EoE is characterized by a mixed inflammatory response, and the EoE transcriptome may be influenced by age and sex. These findings enhance insights into the molecular mechanisms of EoE.

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.

Abstract
INTRODUCTION Eosinophilic esophagitis (EoE) is a chronic inflammatory disease of the esophagus with increasing prevalence worldwide. It is a multifactorial disease caused by a combination of immunologic, genetic, and environmental factors. The clinical presentation of EoE varies largely, especially between different age groups. While diagnostic criteria and therapeutic goals are similar in children and adults, there are differences in treatment, with a more cautious approach in children to avoid growth disturbances. In addition, close monitoring and follow-up are essential in children to ensure uninterrupted growth. AREAS COVERED A search in PubMed/MEDLINE, EMBASE, and SCOPUS databases was conducted to identify relevant studies published between January 2010 and January 2023 to give an overview of the state-of-the-art of EoE epidemiology, diagnosis, and treatment while focusing on similarities and differences between the adult and the pediatric population. EXPERT OPINION The current state of research indicates that while significant progress has been made in understanding and treating EoE, further research and advances are needed to optimize diagnostic strategies, tailored treatment approaches, monitoring, and follow-up, and improve long-term outcomes for patients. With further innovation, the management of EoE can become more precise and tailored, leading to better patient outcomes and improved quality of life.

Abstract
BACKGROUND The presentation of eosinophilic esophagitis (EoE) is heterogeneous, but trends over time are not known. AIM To determine whether clinical and endoscopic phenotypes at EoE diagnosis have changed over the past 2 decades. METHODS In this retrospective cohort study, adults and children with newly diagnosed EoE were phenotyped as follows: (1) inflammatory vs fibrostenotic vs mixed on endoscopy; (2) atopic vs non-atopic; (3) age at symptom onset; (4) age at diagnosis; (5) presence of autoimmune or connective tissue disease; and (6) responsive to steroids. The prevalence of different phenotypes was categorized by 5-year intervals. Multivariate analysis was performed to assess for changes in patient features over time. RESULTS Of 1187 EoE patients, age at diagnosis increased over time (from 22.0 years in 2002-2006 to 31.8 years in 2017-2021; p < 0.001) as did the frequency of dysphagia (67% to 92%; p < 0.001). Endoscopic phenotypes were increasingly mixed (26% vs 68%; p < 0.001) and an increasing proportion of patients had later onset of EoE. However, there were no significant trends for concomitant autoimmune/connective tissue disease or steroid responder phenotypes. On multivariate analysis, after accounting for age, dysphagia, and food impaction, the increase in the mixed endoscopic phenotype persisted (aOR 1.51 per each 5-year interval, 95% CI 1.31-1.73). CONCLUSION EoE phenotypes have changed over the past two decades, with increasing age at diagnosis and age at symptom onset. The mixed endoscopic phenotype also increased, even after controlling for age and symptomatology. Whether this reflects changes in provider recognition or disease pathophysiology is yet to be elucidated.

Yamagata T, Saito H, Fujimoto A, Oomoto K, Ikebata A, Urata J, Tanaka M, Toyozumi Y, Tada S, Hashigo S. Sublingual immunotherapy for cedar pollinosis possibly triggers eosinophilic esophagitis. Clin J Gastroenterol 2024; 17:6-11. [PMID: 38032451 DOI: 10.1007/s12328-023-01881-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 10/16/2023] [Indexed: 12/01/2023]
Abstract
Sublingual immunotherapy (SLIT) is an effective and popular treatment for cedar pollinosis. Although SLIT can cause allergic side effects, eosinophilic esophagitis (EoE) is a lesser-known side effect of SLIT. A 26-year-old male with cedar pollinosis, wheat-dependent exercise-induced anaphylaxis, and food allergies to bananas and avocados presented with persistent throat itching, difficulty swallowing, heartburn, and anterior chest pain 8 days after starting SLIT for cedar pollinosis. Laboratory examination showed remarkably elevated eosinophils, and esophagogastroduodenoscopy revealed linear furrows in the entire esophagus. Histological examination of an esophageal biopsy specimen revealed high eosinophil levels. The patient was strongly suspected with EoE triggered by SLIT. The patient was advised to switch from the swallow to the spit method for SLIT, and the symptoms associated with SLIT-triggered EoE were reduced after switching to the spit method. This case highlights the importance of recognizing SLIT-triggered EoE as a potential side effect of SLIT for cedar pollinosis, especially with the increasing use of SLIT in clinical practice. EoE can occur within a month after initiating SLIT in patients with multiple allergic conditions, as observed in our case. Furthermore, the spit method should be recommended for patients who experience SLIT-triggered EoE before discontinuing SLIT.

Helicobacter pylori infection is associated with decreased odds for eosinophilic esophagitis in Mexican patients. GASTROENTEROLOGIA Y HEPATOLOGIA 2024; 47:149-157. [PMID: 36963464 DOI: 10.1016/j.gastrohep.2023.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 03/01/2023] [Accepted: 03/09/2023] [Indexed: 03/26/2023]
Abstract
BACKGROUND The incidence of eosinophilic esophagitis (EoE) is increasing in some regions of the world. Retrospective studies have found an inverse association with Helicobacter pylori infection (H. pylori). A recent prospective study has questioned this relationship. We aimed to evaluate this relationship in Mexican patients. PATIENTS AND METHODS We evaluated adult patients without prior eradication of H. pylori. Cases were defined by the presence of esophageal symptoms and >15 eosinophils/high power field (HPF) in the esophageal biopsy. Controls were defined by the presence of <15 eosinophils/HPF in esophageal biopsy. H. pylori infection was defined by histology. Patients were matched by age and gender assigning four controls per case. RESULTS We included 190 patients: 38 cases and 152 controls. Cases had higher frequency of atopy, dysphagia, food impaction, peripheral eosinophilia, and endoscopic EoE abnormalities. The overall prevalence of H. pylori was 63.6%. Cases had significantly lower prevalence of H. pylori than controls (36.8% vs. 70.4%, OR 0.21 95% CI 0.08-0.69, p = 0.001). Atopic patients had lower prevalence of H. pylori than non-atopic: 13.1% vs. 50.5% (OR 0.20, 95% CI 0.06-0.69, p < 0.001), particularly allergic rhinitis and food allergy. CONCLUSIONS We observed an inverse relationship between H. pylori and EoE as well as atopy. Studies in experimental models of EoE that clarify the role of H. pylori in this interaction are required, as well as robust studies that include other factors (socioeconomic, cultural, microbiota, etc.) in order to clarify this relationship.

Abstract
BACKGROUND Prior work suggests eosinophilic oesophagitis (EoE) is rare in those aged over 65 years. However, elderly patients with EoE experience a substantial diagnostic delay from symptom onset to diagnosis. AIMS To assess if age predicted whether oesophageal biopsies were obtained in patients with EoE symptoms, what clinical features predict EoE in the elderly, and if EoE phenotype differs between elderly and non-elderly patients. METHODS We conducted a retrospective cohort study utilising the University of North Carolina (UNC) electronic medical record, EoE clinicopathologic database and UNC endoscopy software from July 2008 to April 2021. A sample of 193 elderly and non-elderly patients with dysphagia, chest pain and/or heartburn were assembled. Patients with EoE were newly diagnosed per contemporaneous guidelines. Patient demographics, clinical characteristics and procedural data were extracted. Summary statistics, bivariate and multivariate analyses were performed. RESULTS Of 193 patients, we included 91 elderly (47%) and 102 non-elderly (53%). Age independently predicted the odds of biopsies (adjusted odds ratio (aOR): 0.44 elderly vs. non-elderly; 95% CI: 0.21-0.92). Endoscopic features of EoE, but not symptoms, were more common in elderly than non-EoE elderly patients. Elderly patients with EoE differed from non-elderly only by time to diagnosis (aOR per year of symptoms preceding diagnosis: 1.08, 95% CI: 1.04-1.11). CONCLUSIONS Elderly patients with EoE have <50% the odds of oesophageal biopsies. There were no significant differences between elderly and non-elderly EoE patients, although endoscopic features helped discriminate the two groups. Our findings suggest that older age represents a barrier to EoE diagnosis.

Abstract
BACKGROUND Data on eosinophilic gastrointestinal disorders (EGIDs) are limited in the United Arab Emirates. OBJECTIVE This study aimed to describe the distribution of eosinophilic gastritis/gastroenteritis (EoG/EGE) and eosinophilic esophagitis (EoE) among patients whose data are recorded on the Cleveland Clinic Abu Dhabi (CCAD) systems. METHODS Anonymized aggregate data were obtained from the Clinerion Patient Network Explorer (PNEx®) network installed at the CCAD on patients diagnosed with EoG/EGE (n=17, of whom 11 (64.7%) were females) or with EoE (n=118, of whom 35 (29.7%) were females) between 2015 and 2022; 63 (53.4%) were diagnosed between 2020 and 2022. RESULTS The vast majority of EoE patients visited the gastroenterology clinic (111, 94.1%), followed by the primary care (70, 59.3%), the emergency medicine (60, 50.8%), and the immunology (59, 50%) units. A total of 84 patients with EoE also presented with another type-2 inflammatory condition including allergic rhinitis, food allergy, and atopic dermatitis. Proton pump inhibitors and corticosteroids were widely prescribed, and four patients with EoE have been commenced on biologics since 2020. However, heterogeneity of medication use was identified, warranting local clinical practice guidelines. CONCLUSION A referral network could be established with local and regional reach, which relies on a multidisciplinary approach for the management of EoE and associated type 2 co-morbidities. More studies are needed to better depict the clinical picture of patients with EGIDs in general and EoE, in particular, in terms of diagnosis, pharmacological treatment, non-medical interventions, disease course, and patient-reported outcomes.

Development of a model to identify patients who do not need oesophageal biopsies when eosinophilic oesophagitis is suspected. Aliment Pharmacol Ther 2023; 58:1143-1150. [PMID: 37845804 DOI: 10.1111/apt.17772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 09/04/2023] [Accepted: 10/06/2023] [Indexed: 10/18/2023]
Abstract
BACKGROUND Predictive models for eosinophilic oesophagitis (EoE) may not fully rule in the diagnosis. AIM To develop a reverse model that predicts against EoE to eliminate the need for oesophageal biopsies. METHODS In this two-centre study, a predictive model was developed (Mayo Clinic) and validated (University of North Carolina [UNC]). Cross-sectional data from consecutive adult patients without prior EoE who underwent upper enoscopy with oesophageal biopsies were used. EoE cases had ≥15 eosinophils/high-power field while controls had no eosinophils. Data were collected on patient clinical and endoscopic features. Multiple variable logistic regression was used to identify predictors of non-EoE status while maintaining specificity ≥95%. A secondary model was developed to predict against the need for endoscopy in patients suspected of having EoE without alarm symptoms. RESULTS The Mayo and UNC cohorts consisted of 345 (EoE = 94, non-EoE = 251) and 297 patients (EoE = 84, non-EoE = 213), respectively. A primary model based on clinical and endoscopic features predicted against EoE with c-statistic 0.92 (95% CI: 0.88-0.96), specificity 95%, and sensitivity 65%. This model was validated (UNC) with c-statistic 0.87 (95% CI: 0.82-0.92). A simplified scoring system was created and a threshold of ≥12 points excluded EoE with 95% specificity and 50% sensitivity. A secondary model based on clinical characteristics alone predicted against EoE with c-statistic 0.86 (95% CI: 0.82-0.90), specificity 95% and sensitivity 39% and validated (UNC) with c-statistic 0.78 (95% CI: 0.71-0.85). CONCLUSION A simplified scoring system accurately identified a group of patients with a low likelihood of EoE where unnecessary oesophageal biopsies can be avoided, potentially resulting in resource and cost savings.
