Food-Additive-Induced Urticaria: A Survey of 838 Patients with Recurrent Chronic Idiopathic Urticaria

Abstract

Our results confirmed that food additive hypersensitivity reactions occurred in few RCIU patients using DBPCsingle challenge. The combination of the results of FAFD and DBPCmixed challenge seems to be of considerable practical interest for allergists, internists and dermatologists, rather than the data of clinical history and the results of DBPCsingle challenge, in patients with RCIU.
