A practical focus on sesame allergy and a brief review of other seed allergies.

Abstract

Although seed allergies are relatively rare, sesame allergy has been increasing worldwide and is typically persistent in most patients. Because allergen labeling laws, until just recently, have not required the declaration of sesame as a major allergen, there is a clear need to better understand and potentially treat this food allergy. Although blood and skin prick testing for sesame have limited predictive value, this improves with the use of component diagnostics and skin-prick test with fresh sesame. A thorough history and oral food challenge should be used to diagnose sesame allergy. Treatment of sesame allergy with oral immunotherapy has been demonstrated to be safe and effective in case reports, and in at least one controlled study with a published sesame oral immunotherapy protocol. There is minimum literature with regard to management of other seed allergies.
