Abstract
PURPOSE OF REVIEW Dupilumab is an emerging medication that has shown efficacy for multiple atopic conditions. This review provides insight into the common conditions that are treated, mechanism of action, and continued innovation with the medication. RECENT FINDINGS There continues to be applicability of dupilumab in treating a growing number of atopic conditions. Increasingly younger patient populations with eosinophil based conditions are being approved for this therapy. It is also considered as an additional option treatment for patients who cannot tolerate oral therapy or have adverse effects from other agents. Patients with more severe conditions are finally finding symptom stability while also being able to reduce reliance on corticosteroids. Patients as young as 6 months of age have benefited from treatment. SUMMARY As atopic conditions become more prevalent, dupilumab has been shown to be successful in inducing remission of symptoms. Overall, it continues to be a promising treatment for reducing the burden of disease severity as well as improving the quality of life of affected children.

Abstract
INTRODUCTION Dupilumab, the first US Food and Drug Administration-approved treatment for eosinophilic esophagitis (EoE), lacks real-world data on use and effectiveness. METHODS We conducted a retrospective cohort study of 70 patients with EoE prescribed dupilumab, comparing prescriber type, indication, follow-up, and response. RESULTS Indications varied with gastroenterologists commonly prescribing for treatment-refractory cases and allergists as first-line therapy. Endoscopic assessment was lacking in 25.9%, but those with follow-up showed high histologic remission (92.3% first-line and 85% previous treatment failure). DISCUSSION Dupilumab demonstrates effectiveness across EoE severity, including milder disease without previous treatment failure. Improving follow-up and assessing cost-effectiveness will help clarify its role in the treatment algorithm.

Abstract
Food allergies occur due to a lack of tolerance to the proteins found in foods. While IgE- and non-IgE-mediated food allergies have different clinical manifestations, epidemiology, pathophysiology, and management, they share dysregulated T cell responses. Recent studies have shed light on the contributions of different T cell subsets to the development and persistence of different food allergic diseases. This review discusses the role of T cells in both IgE- and non-IgE-mediated food allergies and considers the potential future investigations in this context.

Abstract
Dupilumab has been approved to treat a variety of atopic disorders and was the first US FDA-approved medication for the treatment of eosinophilic esophagitis (EoE), initially approved in May 2022, with expansion in use to patients as young as 1 year of age weighing at least 15 kg in January 2024. It is a fully human monoclonal antibody that inhibits both IL-4 and IL-13 signaling, suppressing TH2-mediated proinflammatory cytokines, chemokines and IgE implicated in EoE pathogenesis. Phase II and III trials in EoE have demonstrated histologic, endoscopic and symptomatic improvement in disease activity with an overall favorable safety profile. This article will review the available clinical trial data and real-world efficacy of dupilumab in EoE.

Abstract
PURPOSE OF REVIEW Eosinophilic esophagitis (EoE) is a Th2 immune/antigen-mediated disorder characterized by esophageal dysfunction and eosinophilic inflammation. Worsening dysphagia and food impactions are significant complications associated with esophageal remodeling and fibrostenotic disease. This review highlights the most recent research findings pertaining to mechanisms of sub-epithelial fibrosis in EoE, current diagnostic tools, and therapeutic approaches. RECENT FINDINGS Recent studies leveraging publicly available single cell sequencing databases and comparative proteomics have furthered our understanding of the mechanisms mediating fibrosis. Fibroblast crosstalk with the extracellular matrix and with epithelial, endothelial, and T cells have been implicated, with the likely existence of multiple fibroblast sub-types. Accurate diagnosis of remodeling with biopsies remains a challenge due to inadequate depth of sampling. Web-based tools incorporating epithelial findings show promise in predicting subepithelial fibrosis. Impedance planimetry with esophageal distensibility measurements are increasingly utilized tools to assess fibrostenotic severity. Immunostaining and luminal captured proteins associated with remodeling show promise as potential molecular markers of fibrosis. Anti-inflammatory therapy may improve esophageal fibrosis and distensibility, although specific fibrosis-targeted therapy is lacking. SUMMARY Recent studies highlight novel mechanisms of fibrosis in EoE. Improved understanding of these mechanisms may lead to novel diagnostic strategies and therapies, and thereby inform treatment decisions.

Abstract
INTRODUCTION Improvements in symptomatic experience and health-related quality of life (HRQoL) are among the most important treatment benefits in patients with eosinophilic esophagitis (EoE). We assessed the impact of dupilumab treatment on HRQoL, patients' impression of dysphagia, and symptoms beyond dysphagia in adults/adolescents (≥12 years) with EoE in parts A and B of the LIBERTY EoE TREET (NCT03633617) study. METHODS The EoE Symptom Questionnaire (EoE-SQ; frequency and severity of nondysphagia symptoms), EoE Impact Questionnaire (impact of EoE on HRQoL), and Patient Global Impression of Severity and Patient Global Impression of Change of dysphagia were used to assess the efficacy of weekly dupilumab 300 mg vs placebo. RESULTS At week 24, dupilumab reduced EoE-SQ Frequency (least squares mean difference vs placebo [95% confidence interval] part A -1.7 [-2.9, -0.5], part B -1.4 [-2.3, -0.5]; both P < 0.01) and EoE-SQ Severity (part A -2.0 [-3.9, 0.0], P < 0.05, part B -1.5 [-3.0, 0.1], P = 0.07) overall scores, and improved scores across all individual items. Improvement in the dupilumab group was clinically meaningful to patients. Dupilumab also meaningfully improved EoE Impact Questionnaire average scores and improved individual item scores at week 24, particularly emotional and sleep disturbance. More dupilumab-treated patients reported improvement in the Patient Global Impression of Change of dysphagia vs placebo or reported having no symptoms per the Patient Global Impression of Severity of dysphagia at week 24. DISCUSSION Dupilumab reduced the impact of EoE on multiple aspects of HRQoL, patients' impression of dysphagia, and frequency and severity of symptoms beyond dysphagia in adults/adolescents with EoE.

Abstract
We evaluated patients aged 12-20 on dupilumab 300 mg weekly for treatment of eosinophilic esophagitis (EoE) who had ≥1 follow-up endoscopy at a tertiary care pediatric hospital (n = 18). Fifty percent had inflammatory EoE (n = 9), 22% had fibrostenotic EoE (n = 4), and 28% had non-EoE eosinophilic gastrointestinal disease (EGID) with esophageal involvement (n = 5). Ninety-four percent discontinued topical corticosteroids (TCS) 2-4 weeks after starting dupilumab. Eighty-nine percent of inflammatory EoE patients had histological response (<15 eosinophils/high-powered field) after an average of 19.1 weeks. One hundred percent of patients with fibrostenotic disease exhibited histological response after 16.8 weeks. Of patients with non-EoE EGID, 60% achieved esophageal histological response after an average of 40.1 weeks. In a small cohort, dupilumab was very effective for adolescent inflammatory and fibrostenotic EoE despite rapid weaning of TCS. Dupilumab was also somewhat effective for non-EoE EGID with esophageal involvement; however, a longer duration of therapy was required.

High prevalence of response to PPI treatment in children and adolescents with eosinophilic esophagitis in southern Brazil. FRONTIERS IN ALLERGY 2024; 5:1346843. [PMID: 38650863 PMCID: PMC11033356 DOI: 10.3389/falgy.2024.1346843] [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: 11/30/2023] [Accepted: 03/21/2024] [Indexed: 04/25/2024] Open
Abstract
Introduction Eosinophilic esophagitis is a newly recognized entity, in which there is significant evidence available that clearly demonstrates the positive impact of PPIs on reducing esophageal eosinophilia in individuals across different age groups, including children, adolescents, and adults. Multiple mechanisms have been proposed to explain how this treatment effect occurs. In Brazil, there seems to be a lack of studies that have prospectively assessed the clinical and therapeutic response rate in pediatric patients with EoE. The objective of this study was to prospectively evaluate the clinical and therapeutic response of pediatric patients with EoE in a medical center located in southern Brazil, by investigating the effectiveness of PPI treatment. Methods This study is a clinical, prospective, open trial that took place in a pediatric hospital located in southern Brazil. The focus of the study was on patients diagnosed with Eosinophilic Esophagitis (EoE) who were given treatment using omeprazole/esomeprazole at a dosage of 1 mg.kg per dose, twice daily, for a period of 8-12 weeks. Following the treatment period, the patients underwent another endoscopy. Patients who exhibited 15 or less eosinophils in the biopsy conducted after the treatment were considered as responders. Results A total of 27 patients was evaluated (74.1% boys). The average age (± standard deviation) was 8 years (±4). Nineteen patients (70.3%) were considered as responders to PPI treatment: 6 patients-22.2%-exhibited a complete response (defined as having 5 or fewer eosinophil per high power field. Additionally, 13 patients-48.1%-demonstrated a partial response, characterized by eosinophil counts exceeding 5 but less than 15 eos/hpf. When comparing the responder and non-responder groups at presentation, a statistical difference was observed in the prevalence of food refusal as a presenting symptom. Food refusal was found to be more prevalent in the non-responder group (87.5% vs. 26.3%, P = 0.008). No differences were observed in terms of atopy history and endoscopic scores. Upon comparing the histological findings from the post-treatment endoscopy of the two groups, it was observed that PPI responders exhibited a greater tendency to decrease basal cell hyperplasia (P = 0.06) and intercellular edema (P = 0.08). Conclusion In this group of pediatric patients with EoE in Southern Brazil most patients showed a high prevalence of histological, endoscopic, and clinical response to PPI treatment. PPIs showed efficacy in Brazilian patients with EoE, most of whom would probably not be able to adequately undergo other treatments.

Abstract
Eosinophilic esophagitis (EoE) is a chronic, progressive, type 2 inflammatory disease with increasing global prevalence. An eosinophil-predominant inflammation that permeates the epithelium and deeper esophageal layers characterizes the disease. Several cytokines, mainly derived from inflammatory T-helper 2 (Th2) cells and epithelial cells, are involved in perpetuating inflammatory responses by increasing surface permeability and promoting tissue remodeling characterized by epithelial-mesenchymal transition (EMT) and collagen deposition. This leads to esophageal strictures and narrow caliber esophagi, which are proportional a patient's age and untreated disease length. Pathophysiological mechanisms leading to EoE have been described in recent years, and transforming growth factor beta (TGF)-beta have been involved in fibrotic phenomena in EoE. However, evidence on the dependence of these phenomena on TGF-beta is scarce and contradictory. This review provides state-of-the art knowledge on intimate mechanisms of esophageal fibrosis in EoE and its clinical consequences.
