Abstract

Purpose of review

To discuss current methods for grading severe allergic reactions (SARs) in view of the new WAO modified classification system.

Recent findings

While there is not universally accepted system for classifying SAR severity, and due to the high degree of heterogeneity and difficulties for comparisons between the various methods, the new WAO proposal is simple, suitable for use in clinical practice and universally applicable for all allergic reactions, covering the full spectrum of possible grades of severity.

Summary

There is a requirement for a simple and comprehensive system to classify systemic allergic reaction severity. The modification to WAO’s classification of SARs to allergen immunotherapy recently proposed by Cox et al. constitutes an important contribution in the goal of obtaining useful and helpful information for all involved stakeholders.

Keywords
