Food protein-induced enterocolitis syndrome (FPIES) occurs in infants. Typical symptoms include profuse vomiting and/or diarrhea several hours after ingestion of a given food. The disorder is a non-IgE mediated food hypersensitivity. The most frequently involved foods are milk and soy, but some cases of FPIES induced by solid foods have been described. We report 14 patients with FPIES due to fish protein. ⋯ We report 14 patients with FPIES caused by fish protein. The symptoms suggest a form of cell-mediated, non-IgE mediated food hypersensitivity. The gold standard for diagnosis is OC, although caution should be exercised in infants with several reactions or a recent diagnosis. After a period of elimination of the causal food from the diet, tolerance can develop.
