Guideline for the Management of Hereditary Angioedema

The "WAO Guideline for the Management of Hereditary Angioedema" provides credible, evidence-based information for physicians and other health care professionals around the world and allows ease-of-access to relevant scientific and clinical data on HAE, including differential diagnosis and treatment. The document is an in-depth, state of the art resource that refers to and summarizes existing guidelines, consensus documents, and recommendations. The Guidelines are evidenced based, consensus driven and were written by experts in the disease state and a representative from the HAE International Patient Association, without input or presence of industry. After drafting of the Guideline it was reviewed by a larger group of HAE specialists and altered as required. Finally, it was reviewed and approved by the WAO Board of Directors and affiliate Allergy and Immunology Associations that comprise the World Allergy Organization.

A WAO/EAACI update of the Guideline is currently in development.


The Guidelines update is supported through independent education grants from CSL Behring, Pharming, Salix/Valeant, & Shire.
