The history of the drug‐induced enterocolitis syndrome

The diagnosis of drug-induced enterocolitis syndrome (DIES), resembling the typical findings of a well-known disease, the food protein-induced enterocolitis syndrome (FPIES), was acknowledged in the first publication on the topic in 2014. Ten cases of DIES have been described so far. Unanswered questions concerning DIES include its pathogenetic mechanism, natural history, the possible presence of predisposing genetic factors, and the potential existence of its atypical forms. DIES is a recently defined and intriguing clinical entity, similar to FPIES but triggered by drugs. It seems well-defined from the clinical point of view, but its pathogenetic mechanisms are not known. DIES deserves more attention among allergists, especially among the professionals who work with children, and all efforts should be conceived to improve its correct recognition and accurate management.
