About

Bradykinin-mediated angioedema is a rare and disabling disease, characterized by the occurrence of attacks marked by localized swelling of skin, but also of the airways, which can be life-threatening. The unpredictable nature of attacks is a key feature of angioedema, placing patients under constant threat. It seems that there are different patterns of yearly distribution for these attacks, but this is poorly described in the literature. The objectives of the study are to establish different rhythmicity profiles of patients according to the frequency of the attacks; and to identify factors potentially triggering the attacks. For this purpose, patients with bradykinin-mediated angioedema will be monitored daily using a smartphone application. Each day, the application will ask the patient if he or she is having an attack and, if so, the characteristics of the attack and the events preceding it
