What is the treatment for hereditary angioedema?

What is the treatment for hereditary angioedema?

In HAE types I and II, the treatment of choice in acute attacks consists of replacement with commercially available C1 inhibitor (C1-INH) concentrates or kallikrein inhibitor or, if those are unavailable, fresh-frozen plasma. In HAE with normal C1 inhibitor levels, infusion of C1-INH has proven to be ineffective.

Is there a cure for acquired angioedema?

Medicines that boost the levels of C1-I in the body are very effective for treating acquired angioedema. These include Haegarda, Cinryze, and Kalbitor (ecallantide). Another medicine, Firazyr (icatibant), can be used in much the same way as an EpiPen for immediate, self-treatment of an acquired angioedema attack.

What deficiency causes angioedema?

Hereditary angioedema and acquired angioedema (acquired C1 inhibitor deficiency) are caused by deficiency or dysfunction of complement 1 (C1) inhibitor, a protein involved in the regulation of the classical and lectin complement activation pathways.

Is hereditary angioedema life-threatening?

Hereditary angioedema is a potentially life-threatening disorder caused by a genetic defect. The term “edema” means swelling. Hereditary angioedema causes painful episodes of swelling, typically in the face, hands, feet, or genitals. Dangerous swelling can also occur in the airways of the lungs or the intestinal walls.

What medication helps angioedema?

Medicines called danazol and oxandrolone can help reduce the chances of swelling occurring if you have hereditary angioedema. These medicines boost the levels of C1 esterase inhibitor in your blood. Low levels of this substance are what causes the swelling.

Does angioedema get worse over time?

The swelling events can be chronic — recurring over the long term — like in the case of idiopathic angioedema, hereditary angioedema, and acquired angioedema.

Is angioedema an autoimmune disease?

In an estimated 30–50% of the cases, idiopathic angioedema may be associated with an underlying autoimmune disease, such as systemic lupus erythematosus (SLE).

How does C1 inhibitor deficiency cause angioedema?

The deficiency of C1-INH leads to inappropriate activation of the contact-kinin system, release of bradykinin, increased vascular permeability and angioedema [9, 10].

What autoimmune disease causes angioedema?

Why does C1-inhibitor deficiency cause angioedema?

What type of doctor treats hereditary angioedema?

Your healthcare team should feature a doctor who has treated HAE, usually an allergist-immunologist. Other specialists who may be on your HAE care team include dermatologists, genetic counselors, OB-GYNs, and gastroenterologists.

What is the best antihistamine for angioedema?

Antihistamines such as diphenhydramine (Benadryl), hydroxyzine (Visatril), and cetirizine (Zyrtec) are often helpful in managing and preventing episodes of angioedema.
