Autoimmunity is thought to be one of the most frequent causes of chronic urticaria. In about half of patients with chronic idiopathic hives, the explanation is that body's immune system is, in a sense, overactive. The urticaria is "autoimmune". The immune system is attacking the normal tissues of the body and causing hives as a result.
August is Psoriasis Awareness Month.
There are so many autoimmune disorders that I want to write posts about this year. Most of them I have never heard of, and today's autoimmune disorder/disease autoimmune angioedema is no exception. There are two types of angioedema: hereditary or acquired. Acquired angiodema is the type I'm writing about today. It can develop with systemic lupus erythematosus (lupus) or dermatomyositis.
