Hereditary angioedema (hereditary C1 esterase inhibitor deficiency) is an "inherited disorder that is characterized by subcutaneous and submucosal edema in the upper respiratory tract and gastrointestinal tract."[1]
Unregulated kallikrein activation of bradykinin may cause hereditary angioedema:[2]
- Hereditary angioedema types I and II are due to insufficient activity of complement C1 inhibitor protein (C1 esterase inhibitor).[3]
- Hereditary angioedema type III may due to increased activity of coagulation factor XII (Hageman factor).[4][5][6]
Diagnosis
Hereditary deficiency is characterized by normal levels of complement C1q and complement C1 inhibitor protein function.[7] complement C1 inhibitor protein antigen is low in type I and normal in type II.
