Drug allergy - top articles for May/June 2014

Here are my suggestions for some of the top articles about drug allergy for May/June 2014:

Progressive increase in ACEi use has led to a parallel increase in angioedema, with different degrees of severity. ACEI-induced angioedema is associated with high levels of bradykinin and preferentially occurs in females and African-Americans. Less than 10% of patients with ACEI-associated angioedema also develop angioedema episodes after ARB intake. Therefore, ARBs may be reserved for patients with high therapeutic need for angiotensin inhibition. http://buff.ly/17fkvvx

"Most patients with angioedema related to ACE inhibitor usually tolerate ARBs". The operative word is "most". http://buff.ly/NankbP

Nonimmediate reactions to contrast media are T-cell mediated. Provocation testing is needed to find a tolerated agent http://buff.ly/1208TY3

Allergists were able exclude antibiotic allergy in more than 90% of children who had a negative intradermal test (via a challenge) http://buff.ly/1dgFeQz

Penicillin "allergy" history is self-reported by about 1 out of 10 persons. 19 of 20 patients who think they are allergic to penicillin are misinformed. 9 out of 10 patients who report penicillin allergy are proven to be tolerant when assessed by penicillin skin testing. 30 million people report a penicillin allergy in the US - 27 million of them are likely not allergic. Hospital length of stay for a patient with a self-reported allergy was 0.59 days longer http://buff.ly/1lFJoIZ
