Children with sensitivity to peanuts and tree nuts were 10 times more likely to be sensitized to sesame seeds, and children with clinical histories of allergies to the nuts were 10 times more likely to be allergic to sesame seeds, a study found.

Researchers in Boston conducted a retrospective chart review of 191 children who underwent skin-prick testing to sesame and 40 children who underwent skin-prick testing to coconut. A sesame sensitivity was more likely in children with positive skin-prick testing to peanuts (OR=6.7; 95% CI, 2.7–16.8) and tree nuts (OR=10.5; 95% CI, 4.0–27.7). Children with clinical histories of peanut and tree nut allergies were more likely to have a history of sesame reaction (OR=10.2; 95% CI, 2.7–38.7), according to the study

A similar relationship between peanut and tree nut sensitivity and coconut sensitivity could not be established, the researchers reported.
