Patients present with white, circumscribed nonpruritic edemas that remain for a period of 48 to 72 hours and recur with variable frequency. Edemas may involve the digestive tract resulting in a clinical picture similar to that seen in intestinal occlusion syndrome, sometimes associated with ascites and hypovolemic shock. Dental procedures are a triggering factor for laryngeal edema. Edemas of the face are a risk factor for laryngeal involvement.

Three types of HAE have been described. Transmission is autosomal dominant and most cases involve heterozygotes.

The edemas are triggered by increased anngioedema of the blood vessels in response to elevated levels of bradykinin as a result of the C1-INH deficiency. HAE type 3 predominantly involves females, with the use of estrogen-containing oral contraceptives and pregnancy being precipitating factors.

HAE type 3 is not caused by C1-INH deficiency but is associated with an increase in kininogenase activity leading to elevated levels of bradykinin. Some cases are associated with coagulation factor 12 Hageman factor; F12 ; 5qqter gain-of-function mutations but other genetic anomalies remain to be identified.

The differential diagnosis should include acquired angioedema see this termintestinal occlusion syndrome and histamine-induced angioedema of allergenic or nonallergenic origin generally associated with urticaria.

Screening of family members, including asymptomatic individuals, is recommended. Corticosteroid treatments are not effective. In Europe, acute attacks should be treated with subcutaneous icatibant a bradykinin receptor antagonist or intravenous administration of C1-INH concentrate.

Prophylactic treatment with tranexamic acid or danazol may be proposed for patients with frequent episodes.

The vital prognosis is good for patients who have been diagnosed and have access to the proper treatment in case of an ear-nose-throat ENT edema. Significant morbidity may be associated with digestive involvement resulting in pain and patients becoming bedridden for hereditairo least three days following an episode.
