Understanding the Evolving Landscape: New Nomenclature for Allergic Diseases and Hypersensitivity Reactions

28 May 202418 June 2024 drugallergydetective.com

Recent advances in immunology have deepened our understanding of allergic diseases and hypersensitivity reactions. Traditionally classified using the Gell-Coombs system (Types I-IV), the increasing complexity of these conditions has led to a proposed new nomenclature, especially for Type IV hypersensitivity. This blog provides an overview of the new classification and its clinical implications. Overview of Traditional Hypersensitivity Classification The Gell-Coombs classification includes: Here are the novel classifications of hypersensitivity reactions according to the new European Academy of Allergy and Clinical Immunology Position Paper published in Allergy. 2023 Nov;78(11):2851-2874. and…

AI Detectives: How Machine Learning Could Revolutionize Drug Allergy Diagnosis

16 October 202314 October 2024 drugallergydetective.com

Introduction Drug allergies can have severe consequences, necessitating accurate diagnosis and management. A research group focused on drug allergies has made significant progress in this area. They developed and evaluated two drug allergy prediction models, publishing the data in the Journal of Allergy and Clinical Immunology. The Models The study utilized a machine learning approach, specifically a random forest (RF) model and a logistic regression (LR) model, to identify culprit drugs based on drug-specific IFN-γ-releasing cells and clinical parameters in non-immediate drug hypersensitivity. The RF model achieved an average AUROC…
