Who We Are



About us

Quebec’s hereditary angioedema association, (AOHQuebec) aims to contribute by improving the health and quality of life of people with immune deficiency or waiting for a diagnosis. In addition to raising public awareness of the disease, the organization’s mission is to train medical personnel so that they can make the right diagnosis and refer patients to specialists. The appropriate treatments will improve the quality of life of these patients, on a daily basis.

The repercussions of ignorance of this disease are as serious as the disease itself. Many tragedies can be avoided with a good diagnosis. Many patients experienced horror stories such as ablation of a healthy organ, transfer to psychiatry, or even patients who were considered addicts to drugs as they constantly asked for painkillers to relieve their symptoms when consulting the hospitals’ ER. Even deaths could have been avoided with the right diagnosis.
