HAE: Hereditary angioedema (hae) is caused by a an uncontrolled activation of a complex cascade of proteins called complement. Hae is a result of a deficiency or lack of functional c1 esterase inhibitor protein.

Hereditary angio ede: Hereditary angioedema (ha) is a disease that is typically noted to run in families. It is causes by low levels or poor function in a controller protein called c-1 esterase inhibitor. If swelling (angioedema) occurs with hives, then the angio edema is unlikely to be due to this rare problem. Typical angioedema develops quickly, often maximally within one hour. Ha may swell slowly over many hrs. ...Read more
Allergy or not: Angioedema such as swelling of the tongue or lips can occur as the result of an allergy to food or medication. It is usually associated with hives (urticaria). The presence of hives essentially rules out the allergic cause making hereditary or acquired c-1 inhibitor deficiency likely. However, the lack of hives does not rule out allergy. See an allergist for further evaluation either way! ...Read moreSee 1 more doctor answer
It depends: Great question. It really depends on two factors: 1. The severity of the reactions, and 2. The frequency of the reactions. When the reactions become too severe and/or too frequent, prophylactic treatment is recommended. Now, what does too severe/frequent mean? It depends on the person. Ultimately, when the reactions impact a patient's daily life, it's time to consider prophylaxis. ...Read moreSee 1 more doctor answer

I was tested for suspected Hereditary Angioedema. The results came back showing my C1-INH function 58% and antigen 59% (range 70-130). What does mean?
Probably: The findings are compatible with HAE especially in the presence of a low C4 level and compatible features of HAE. Many effective treatments are available and I think the next step is for you to consult an allergist for options in treating this potentially life-threatening condition. ...Read more
C-1 inh is <40% of the expected norm but C4 level normal, wats this mean?Does this mean hav hereditary angioedema?Hx of swelling tongue, nose, lips, vomit
Can't rule out: A normal c4 would be unusual for hae. You don't mention whether c1 inh level was functional activity or level of protein. Functional (activity) complement tests are extremely dependent on the way the specimen is handled. Both tests should probably be repeated. To sort things out, you should see a board-certified allergist immunologist. ...Read moreSee 1 more doctor answer
How long can a chronic urticaria last? Apparentely it is related with hashimoto thyroiditis.. Any idea? Its been 1year of hives and angioedemas.
Can be a long time: The association with hashimoto's thyroiditis is generally just thought to be that people who make antibodies to one thing inappropriately (thyroid) are more likely to make antibodies to other things inappropriately (mast cell receptors which can be a cause for urticaria). Most chronic urticarias last 2 weeks to 2 months, but 10-20% can last more than 2 years. ...Read more
