Study summary

Angioedema is a disease characterized by the appearance of self-limiting edema that last 1-5 days and affect the subcutaneous tissue and/or gastrointestinal and oropharyngeal mucosa. In this last location edema can be lethal causing asphyxia, in all other cases full recovery is complete. Attacks can appear as part of the syndrome urticaria angioedema and can be of allergic origin. But there is a group of non-allergic angioedema that occur without hives and can be either hereditary or acquired. These angioedema are identified in some cases on the basis of etiology, in others are identified by the mediator and an overall classification of these forms of angioedema was published in 2014 as a result of a consent conference organized by the proponents of this registry. Being these forms of angioedema rare, there are not significative case studies inclusive of a high number of patients. This registry aims to collect in a single place a high number of subjects with recurring angioedema and without urticaria.

Read the detailed description

The Grenoble center is the registry coordinator at the national level. It will contract directly with the Cloud R Company and will be in charge of coordinating the associated centers. It will therefore send the necessary documents for the good execution of the study, will ask each center to respect the current French regulatory, will organize and finance the set-up of the register in the associated centers.

The coordinating center will also centralize requests for data, publications or creation of additional eCRF pages of associated centers. It will be able to organize a national scientific committee every 6 months. It will thus be the link between the French centers, the scientific committee of the registry and the company Cloud R.

The coordinating center will also be responsible for enter and reliability of patient data from it center, as well as the associated centers.

Role of associated centers Associated Centers will be responsible for capturing and data reliability of their patients in eCRF, they will also create a personal account for each patient so that it can download the application "cloud R HAE carnet de suivi".

Investigators referent patient will have validated at each visit or after contact with the patient crisis returned to the patient via it electronic diary.

Associated Centers will keep informed twice a year the coordinator center of the state of inclusions in the register.
