Angioneurotic edema |
Angioedema is a form of localized swelling of the deeper layers of the skin and fatty tissues underneath the skin. Angioedema can occur as a result of an allergic reaction, in association with other diseases (such as blood vessel
inflammation, vasculitis), with cancers (such as lymphoma), or for unknown reasons. Hereditary angioneurotic edema, also referred to as hereditary angioedema, is an inherited form of angioedema. Patients with hereditary angioneurotic edema from birth lack
an inhibitor protein (called C1 esterase inhibitor) that normally prevents activation of a cascade of proteins that lead to the swelling of angioedema. Patients with hereditary angioneurotic edema can develop recurrent attacks of swollen tissues, pain in
the abdomen, and swelling of the voice box (larynx), which can cause impaired breathing. The diagnosis of hereditary angioneurotic edema is suspected when a patient has a history of recurrent angioedema. It is confirmed by finding abnormally low levels of
C1 esterase inhibitor in the blood. Treatment options of hereditary angioneurotic edema include antihistamines and male steroids (androgens) that can also prevent the recurrent attacks. |
