AI Article Synopsis

  • The rising prevalence of food allergies emphasizes the need for new prevention methods, effective treatments, and reliable risk assessment tools due to the varying degrees of allergen digestion in individuals.
  • Recent research highlights the importance of understanding the digestive system and its impact on food allergens, focusing on how food processing and digestion contribute to allergen stability.
  • It is noted that allergen digestibility is influenced by food processing, digestive conditions, and the overall food matrix, making it difficult to predict allergen immunogenicity based solely on protein stability.

Article Abstract

Purpose Of Review: The globally rising food allergy prevalence is associated with the urgent need for new disease prevention methods, efficient treatment, and reliable risk assessment methods for characterization of food allergens. Due to inter-individual variations in the digestive system, food allergens are degraded to a different extent in each person. Food processing also influences allergen digestion.

Recent Findings: In this review, we provide an overview of the digestive system with focus on relevance for food allergy. Main food proteins causing allergic reactions are evaluated, and the combined role of food processing and digestion for allergen stability is highlighted. Finally, clinical implications of this knowledge are discussed. Recent literature shows that allergen digestibility is dependent on food processing, digestive conditions, and food matrix. Digestion affects proteins allergenicity. It is currently not possible to predict the immunogenicity of allergens solely based on protein stability.

Anaphylaxis, the most severe end of the spectrum of allergic reactions, has shown increasing incidence globally over recent years. This hypersensitivity reaction can occur at any age, including infancy. Recent data, although scarce, show that anaphylaxis is increasingly reported in infancy, with food identified as the leading cause of anaphylaxis cases in this age group.

The effect of formula type on the prognosis of allergic proctocolitis due to cow's milk allergy.

Allergol Immunopathol (Madr)

Department of Pediatric Allergy and Immunology, Cemil Tascioglu City Hospital, University of Health Sciences, Istanbul, Turkey.

Background: Food protein-induced allergic proctocolitis is a nonimmunoglobulin E-mediated, self-limited food allergy of the rectum and the colon. Cow's milk protein is the most common allergen responsible for the disease.

Objective: This study aimed to investigate the roles of different types of formulas in building early tolerance to food protein-induced allergic proctocolitis in infants.

Drug-induced enterocolitis syndrome (DIES), little known due to its recent description, is analogous to food protein-induced enterocolitis syndrome (FPIES). Both processes are more frequent in pediatric age and share diagnostic criteria, the main one being the appearance of persistent vomiting 1-4 hours after ingestion of the drug or food, in the absence of IgE-mediated allergy symptoms.

Background: Asthma, a chronic inflammatory lung disease, is one of the leading causes of disability, demands on health resources, and poor quality of life. It is necessary to identify asthma-related risk factors to reduce the presence and development of symptoms.

Objective: This study aimed to explore the association of multiple possible factors with asthma symptoms in two subpopulations, children, adolescents, and adults, in six cities in Colombia.

This study aimed to characterize the profile of probable anaphylaxis cases treated at a private pediatric hospital emergency department in São Paulo. It investigated triggering factors, the presence of cofactors, treatments administered, and follow-up for these cases through interviews with the patients' families. A single-center cross-sectional study analyzed medical records of children and adolescents treated between 2016 and 2020.
