- Recent studies offer new insights into the pathogenesis and treatment of this condition, which have relevance not only to these patients, but to those with classic forms of hereditary angioedema as well. (biomedcentral.com)
Levels of C1 inhibitor2
- Mutations that cause hereditary angioedema type I lead to reduced levels of C1 inhibitor in the blood, while mutations that cause type II result in the production of a C1 inhibitor that functions abnormally. (medlineplus.gov)

Symptoms3
- As the symptoms begin to diminish, the white count slowly begins to decrease, returning to normal when the attack subsides. (wikipedia.org)
- As the symptoms and diagnostic tests are almost indistinguishable from an acute abdomen (e.g. perforated appendicitis) it is possible for undiagnosed HAE patients to undergo laparotomy (operations on the abdomen) or laparoscopy (keyhole surgery) that turns out to have been unnecessary. (wikipedia.org)
- Symptoms of hereditary angioedema typically begin in childhood and worsen during puberty. (medlineplus.gov)
Laryngeal edema1

Inhibitors5
- In hereditary angioedema, bradykinin formation is caused by continuous activation of the complement system due to a deficiency in one of its prime inhibitors, C1-esterase (aka: C1-inhibitor or C1INH), and continuous production of kallikrein, another process inhibited by C1INH. (wikipedia.org)

Bradykinin2
- Various mechanisms that interfere with bradykinin production or degradation can lead to angioedema. (wikipedia.org)
- As a result, more bradykinin is generated and blood vessel walls become more leaky, which leads to episodes of swelling in people with hereditary angioedema type III. (medlineplus.gov)
Severe3
- Severe attacks of angioedema can herald the onset of systemic anaphylaxis, characterized initially by dyspnea. (medscape.com)
- Some patients with very low C1INH levels have few attacks, whereas others with much higher levels of C1INH have much more severe disease. (medscape.com)
