Conclusion
In summary, we reviewed a large French cohort of children with FPIES. The main culprit foods were CM, hen’s egg, and fish. The overall prognosis remained good, as half of the cohort had outgrown FPIES by 2 years of age. FPIES to seafood products and severe forms of FPIES were associated with delayed tolerance. IgE sensitization was not a risk factor for persistent FPIES.
