Abstract:
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.
Insights
Drug-induced enterocolitis syndrome (DIES) mimics food protein-induced enterocolitis syndrome (FPIES) but is triggered by medications. Further research is needed to understand DIES pathogenesis, natural history, and genetic factors.
Area of Science:
- Allergy and Immunology
- Pediatric Gastroenterology
- Clinical Pharmacology
Background:
- Drug-induced enterocolitis syndrome (DIES) is a recently identified condition.
- DIES shares clinical similarities with food protein-induced enterocolitis syndrome (FPIES).
- Currently, only ten cases of DIES have been documented.
Purpose of the Study:
- To highlight the clinical characteristics of DIES.
- To emphasize the need for increased awareness and research into DIES.
- To differentiate DIES from FPIES and other gastrointestinal disorders.
Main Methods:
- Literature review of published DIES cases.
- Clinical comparison between DIES and FPIES.
- Analysis of diagnostic challenges and management strategies.
Main Results:
- DIES is clinically similar to FPIES but is drug-induced.
- Pathogenesis, natural history, and genetic factors of DIES remain largely unknown.
- Accurate recognition and management of DIES are crucial but challenging.
Conclusions:
- DIES is an emerging clinical entity requiring further investigation.
- Allergists and pediatric specialists should be aware of DIES.
- Understanding DIES pathogenesis is essential for improved patient care.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
