In a study conducted by Romano et al., involving 440 patients suspected of NSAID hypersensitivity who underwent skin prick tests, specific IgE measurements, and provocation tests with both drugs and foods, NSAID hypersensitivity was excluded in 162 patients, while, among 75 patients with a confirmed food allergy, nine were classified as NEFA cases and 66 as NIFA [12]. Here, IGHE is linked to food allergy.
