Dupilumab for Eosinophilic Esophagitis in Patients 1 to 11 Years of Age.

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).

Tolerance development in cow's milk-allergic children receiving amino acid-based formula with synbiotics: 36-Months follow-up of a randomized controlled trial (PRESTO Study).

The objective of the present study is to assess the rates of acquired tolerance to cow's milk (CM) after 36 months in subjects who consumed amino acid-based formula with synbiotics (AAF-S) or amino acid-based formula without synbiotics (AAF) during a 1-year intervention period in early life as part of the PRESTO study (Netherlands Trial Register number NTR3725). Differences in CM tolerance development between groups were analysed using a logistic regression model. Results show that the proportion of subjects (mean [±SD] age, 3.

Food insecurity and allergic diseases: A call to collective action.

Food security encompassess the concept of access by all people at all times to enough food for an active, healthy life. Conversely, food insecurity (FI) refers to household-level economic and social conditions of limited or uncertain access to adequate food. FI is a key social determinant of health that can negatively affect nutrition and health outcomes, as it is estimated that 10.

Implementation of a Respiratory Therapist-Driven Protocol for Spirometry and Asthma Education in a Pediatric Out-Patient Primary Care Setting.

Background: Best practice guidelines for asthma management recommend education and spirometry at specific intervals. A written asthma action plan with education and spirometry is ordered at the discretion of physicians at our institution. An initial chart review revealed that asthma education and spirometry were not consistently ordered in the pediatric primary care clinics.

A Clinical Severity Index for Eosinophilic Esophagitis: Development, Consensus, and Future Directions.

Background & Aims: Disease activity and severity of eosinophilic esophagitis (EoE) dictate therapeutic options and management, but the decision-making process for determining severity varies among practitioners. To reduce variability in practice patterns and help clinicians monitor the clinical course of the disease in an office setting, we aimed to create an international consensus severity scoring index for EoE.

Methods: A multidisciplinary international group of adult and pediatric EoE researchers and clinicians, as well as non-EoE allergy immunology and gastroenterology experts, formed 3 teams to review the existing literature on histology, endoscopy, and symptoms of EoE in the context of progression and severity.

International Consensus Recommendations for Eosinophilic Gastrointestinal Disease Nomenclature.

Background & Aims: Substantial heterogeneity in terminology used for eosinophilic gastrointestinal diseases (EGIDs), particularly the catchall term "eosinophilic gastroenteritis," limits clinical and research advances. We aimed to achieve an international consensus for standardized EGID nomenclature.

Methods: This consensus process utilized Delphi methodology.

Efficacy and safety of oral immunotherapy in children aged 1-3 years with peanut allergy (the Immune Tolerance Network IMPACT trial): a randomised placebo-controlled study.

Background: For young children with peanut allergy, dietary avoidance is the current standard of care. We aimed to assess whether peanut oral immunotherapy can induce desensitisation (an increased allergic reaction threshold while on therapy) or remission (a state of non-responsiveness after discontinuation of immunotherapy) in this population.

Methods: We did a randomised, double-blind, placebo-controlled study in five US academic medical centres.

Development of a core outcome set for therapeutic studies in eosinophilic esophagitis (COREOS).

Background: End points used to determine treatment efficacy in eosinophilic esophagitis (EoE) have evolved over time. With multiple novel therapies in development for EoE, harmonization of outcomes measures will facilitate evidence synthesis and appraisal when comparing different treatments.

Objective: We sought to develop a core outcome set (COS) for controlled and observational studies of pharmacologic and diet interventions in adult and pediatric patients with EoE.

Tolerance development in cow's milk-allergic infants receiving amino acid-based formula: A randomized controlled trial.

Background: Tolerance development is an important clinical outcome for infants with cow's milk allergy.

Objective: This multicenter, prospective, randomized, double-blind, controlled clinical study (NTR3725) evaluated tolerance development to cow's milk (CM) and safety of an amino acid-based formula (AAF) including synbiotics (AAF-S) comprising prebiotic oligosaccharides (oligofructose, inulin) and probiotic Bifidobacterium breve M-16V in infants with confirmed IgE-mediated CM allergy.

Methods: Subjects aged ≤13 months with IgE-mediated CM allergy were randomized to receive AAF-S (n = 80) or AAF (n = 89) for 12 months.

Eosinophilic gastrointestinal disease below the belt.

Eosinophilic gastrointestinal diseases (EGIDs) are rare diseases of the gastrointestinal tract caused by allergic inflammation and gastrointestinal dysfunction. Initially described in 1978, recognition of these disorders has greatly increased over the past several decades. Thus far, eosinophilic esophagitis (EoE) has received the most focus, leading to significant advances in understanding of disease mechanisms, widely adopted guidelines for diagnosis and management, and ongoing clinical trials to provide expanded treatment options.

Increasing Rates of Diagnosis, Substantial Co-Occurrence, and Variable Treatment Patterns of Eosinophilic Gastritis, Gastroenteritis, and Colitis Based on 10-Year Data Across a Multicenter Consortium.

Objectives: The literature related to eosinophilic gastritis (EG), gastroenteritis (EGE), and colitis (EC) is limited. We aimed to characterize rates of diagnosis, clinical features, and initial treatments for patients with EG, EGE, and EC.

Methods: In this retrospective study, data were collected from 6 centers in the Consortium of Eosinophilic Gastrointestinal Researchers from 2005 to 2016.

Emerging drugs for eosinophilic esophagitis.

Eosinophilic esophagitis (EoE) is rare but incidence and prevalence is increasing. EoE is characterized by eosinophilic inflammation of the esophagus causing gastrointestinal symptoms such as abdominal pain, vomiting, reflux, dysphagia, and food impactions. If untreated, remodeling and fibrosis of the esophagus can occur and stricture formation may result.
