Q

mechanisms of angioedema (5)

A

1- mast cell degranulation (histamine and IgE mediated/allergic)

deficient C1-INH activity

A

angioedema

hereditary - type I (less C1-INH) and type II (normal levels but dysfunctional C1-INH)

A

allergic - histamine
ACE and hereditary/acquired - C1-INH concentrate
autoimmune - steroids
