Purpose Of Review:
First described in the mid 20th century, it was just in the last decade that diagnostic and treatment guidelines for food protein-induced enterocolitis syndrome (FPIES) were established. Awareness of the diagnosis is improving, and epidemiologic data are emerging.
Recent Findings:
Recent studies suggest that FPIES may affect as many as 0.5% of children worldwide. FPIES in adults is usually triggered by seafood and may be more common than previously thought. Many patients with FPIES have other allergic disorders.
Summary:
With refined diagnostic criteria and improved awareness, FPIES is now diagnosed with increasing frequency, and epidemiologic data are emerging. FPIES appears to be increasing in prevalence, and the frequent association with other allergic disorders suggests a shared predisposition or immune mechanism that remains to be elucidated.

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...
