Comparative StudyNorth-south differences in US emergency department visits for acute allergic reactions.

These observational data are consistent with the hypothesis that vitamin D may play an etiologic role in anaphylaxis, especially food-induced anaphylaxis.

Asthma and the prospective risk of anaphylactic shock and other allergy diagnoses in a large integrated health care delivery system.
The association between asthma and anaphylaxis remains poorly understood. ⋯ In this insured population, asthma was prospectively associated with increased risk of anaphylactic shock and other allergy diagnoses. However, the effect of asthma severity was not consistent across outcome measures.
