A modified grading system for systemic allergic reactions (SARs) is proposed to standardize severity classification. This aims to improve safety outcome comparisons in clinical trials and pharmacovigilance for anaphylaxis and other allergic reactions.

Area of Science:

  • Allergy and Immunology
  • Clinical Pharmacology
  • Public Health

Background:

  • No universal grading system exists for systemic allergic reactions (SARs), including anaphylaxis.
  • Inconsistent application of anaphylaxis definitions hinders research and clinical practice.
  • Difficulty in comparing safety outcomes across studies and pharmacovigilance data.

Purpose of the Study:

  • To present a modified World Allergy Organization (WAO) grading system for SARs.
  • To make the grading system applicable to SARs from any cause.
  • To enable classification of less severe SARs for improved reporting.

Main Methods:

  • Modification of the 2010 WAO grading system for allergen immunotherapy SARs.
  • Basis of the system: organ system involvement and reaction severity.

  • Final grade determined by a healthcare professional post-event.

    • Main Results:

    • The proposed system allows classification of less severe SARs.
    • Addresses potential underreporting or overreporting in studies.
    • Facilitates better safety comparisons across diverse settings.

    Conclusions:

    • A modified, universal SAR grading system is proposed.
    • Standardized classification will enhance safety data interpretation.
    • Universal adoption will improve comparative analysis of treatments and protocols.
