National Prospective Study of Children Aged 0 to 17 Years with Acute Food Protein Induced Enterocolitis Syndrome FPIES in France Tracking Clinical Features, Allergy Testing, and Tolerance Over Three Years

What this Trial Is About

Food Protein Induced Enterocolitis Syndrome FPIES is a type of non-IgE mediated food allergy that usually occurs in infancy and is often not well known by clinicians. The study aims to collect clinical information and allergy test results from children diagnosed with the acute form of FPIES and to observe their condition over three years. It seeks to better understand the evolution of FPIES, including atypical forms, with no prior prospective data available from France. Children diagnosed with acute FPIES will be followed in this national prospective study conducted at sixteen French centers. Allergy tests such as oral food challenges, skin prick tests, and IgE blood tests will be used for diagnosis and monitoring. Patients will be seen at an initial visit and then annually for up to three years. If tolerance to the offending food is not acquired, an oral food challenge will be performed in the hospital for confirmation. Participants will undergo yearly allergist visits for evaluation of symptoms and allergy testing. Researchers will measure the rate of tolerance acquisition to foods over one, two, and three years post-inclusion, as well as the progression to IgE sensitization and clinical IgE-mediated allergy. Additional outcomes include the presence of multiple FPIES episodes and related atopic conditions. The study will provide insights into the natural history and management of FPIES in children.
