Hereditary angioedema

Quincke disease; HAE - Hereditary angioedema; Kallikrein inhibitor - HAE; Bradykinin receptor antagonist - HAE; C1-inhibitors - HAE; Hives - HAE

Hereditary angioedema is a rare but serious problem with the immune system. The problem is passed down through families. It causes swelling, particularly of the face and airways, and abdominal cramping.


Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.
