Food protein-induced enterocolitis syndrome (FPIES) is an allergic disease, probably non-IgE-mediated, with expression predominantly in the GI tract. The most characteristic symptom is repeated, debilitating vomiting. It occurs 2−6 h after ingestion of culprit food and is usually accompanied by pallor and lethargy. There may be diarrhea, and in 10−20% of cases, severe hypotension. These symptoms resolve completely within a few hours. The food most frequently involved is cow's milk, followed by rice, but many other foods may be involved. The prognosis is generally good in a few years. In this review the authors try to cope, with the help of some case histories, with the practical clinical aspects of FPIES. The authors also try to provide a management approach based on current knowledge, and finally, to point out the aspects of FPIES that are still controversial.
