Food protein-induced enterocolitis syndrome.

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy that primarily affects the gastrointestinal tract. The underlying pathophysiology of FPIES has yet to be fully elucidated; however, FPIES is believed to be secondary to intestinal inflammation after exposure to a food antigen, which thereby leads to increased permeability and fluid shifting into the intestinal lumen. FPIES is categorized into acute and chronic forms.

Factors Affecting Adherence in Allergic Disorders and Strategies for Improvement.

Addressing patient adherence is a key element in ensuring positive health outcomes and improving health-related quality of life for patients with atopic and immunologic disorders. Understanding the complex etiologies of patient nonadherence and identifying real-world solutions is important for clinicians, patients, and systems to design and effect change. This review serves as an important resource for defining key issues related to patient nonadherence and outlines solutions, resources, knowledge gaps, and advocacy areas across five domains: health care access, financial considerations, socioenvironmental factors, health literacy, and psychosocial factors.

Volunteerism Addressing Environmental Disparities in Allergy (VAEDIA): The presidential initiative to combat environmental injustice in allergy and immunology-a Work Group Report of the AAAAI VAEDIA task force.

Many vulnerable people lose their health or lives each year as a result of unhealthy environmental conditions that perpetuate medical conditions within the scope of allergy and immunology specialists' expertise. While detrimental environmental factors impact all humans globally, the effect is disproportionately more profound in impoverished neighborhoods. Environmental injustice is the inequitable exposure of disadvantaged populations to environmental hazards.

Clinical and molecular correlates of the Index of Severity for Eosinophilic Esophagitis.

Background: The Index of Severity for Eosinophilic Esophagitis (I-SEE) is a new expert-defined clinical tool that classifies disease severity of eosinophilic esophagitis (EoE).

Objective: We aimed to determine whether I-SEE is associated with patient characteristics, molecular features of EoE, or both.

Methods: We analyzed a prospective cohort of patients with EoE from the Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR).

Challenging assumptions about the demographics of eosinophilic gastrointestinal diseases: A systematic review.

Background: The demographic characteristics of patients with eosinophilic gastrointestinal diseases (EGIDs) are poorly understood. Population-based assessments of EGID demographics may indicate health disparities in diagnosis.

Objectives: We aimed to characterize the demographic distribution of EGIDs and evaluate the potential for bias in reporting patient characteristics.

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.

Development of a mini pig model of peanut allergy.

Introduction: The prevalence of peanut allergies is increasing, emphasizing the need for an animal model to enhance our understanding of peanut allergy pathogenesis and to advance diagnostic tools and therapeutic interventions. While mice are frequently used as model organisms, their allergic responses do not fully mirror those observed in humans, warranting the exploration of a higher animal model. The porcine gastrointestinal system closely resembles that of humans, and exhibits allergy symptoms akin to human responses, making pigs a promising model for peanut allergy research.

Health disparities in allergic diseases.

Purpose Of Review: Healthcare disparities impact prevalence, diagnosis, and management of allergic disease. The purpose of this review is to highlight the most recent evidence of healthcare disparities in allergic conditions to provide healthcare providers with better understanding of the factors contributing to disparities and to provide potential management approaches to address them. This review comes at a time in medicine where it is well documented that disparities exist, but we seek to answer the Why , How and What to do next?

Recent Findings: The literature highlights the socioeconomic factors at play including race/ ethnicity, neighborhood, insurance status and income.

Addressing Health Equity in Food Allergy.

Social determinants of health can lead to poor health outcomes for food-allergic patients, including limited access to allergen-free foods and specialty care. Housing and transportation limitations can worsen social factors including food insecurity, poor early food introduction, increased reactivity to foods, lower tertiary/allergy care utilization, and increased emergency department utilization. A key component of addressing health equity involves valuing all people with sustained, focused efforts to address social determinants of health.
