Perspectives in the validation of DEFASE: a paradigm shift in food allergy management.

Purpose of Review: To explore the groundbreaking international consensus on the DEFASE (DEfinition of Food Allergy Severity) project as a revolutionary grading system for IgE-mediated food allergy severity. Against the backdrop of the growing public health challenge posed by food allergy, this article delves into the importance of validating and implementing DEFASE in real-world clinical settings.
Recent Findings: With new therapeutic options available for food allergy, including biologics alongside immunotherapy, it is urgent to properly support clinical decision-making in the management of the disease. The DEFASE score is the first international consensus-based grading system of severity associated with food allergy as a whole disease embracing multidisciplinary perspectives from different stakeholders involved. In its current version, this comprehensive scoring system has been developed to be used in research settings.
Summary: The review emphasizes the potential impact of DEFASE on patient outcomes, healthcare management, and resource allocation, underscoring its significance for the allergy scientific community. Future research should focus on internal and external validation of the scoring system, targeting these models to various food allergenic sources, populations, and settings.
