Introduction: Food protein-induced enterocolitis syndrome (FPIES) is a form of non-IgE-mediated gastrointestinal food allergy. FPIES is considered a rare food allergy disorder and is often under-recognized. Therefore, clinicians should have a better understanding of its manifestations and maintain a high index of suspicion for a correct diagnosis. To this end, information about differences in the characteristics of caregiver-reported and physician-diagnosed FPIES is important. Methods: The present, national, multicentric, prospective birth cohort study, called the Japan Environment and Children's Study (JECS), enrolled a general population of 104,062 fetal records. The characteristics of FPIES in 1.5-year-old children were categorized as cases reported by caregivers or as those diagnosed by a physician using questionnaire data. Results: The prevalence of caregiver-reported and physician-diagnosed FPIES cases was 0.69% and 0.06%, respectively. Among the former, the most common causative food was hen's egg (HE), and the second most common causative food was cow's milk (CM) (51.0% and 17.1% of patients responded to HE and CM, which accounted for 46% and 15% of all the causative foods, respectively). Conversely, among the physician-diagnosed cases, the most common causative food was CM followed by HE (57.7% and 36.5% of patients responded to CM and HE, which accounted for 46% and 29% of all the causative foods, respectively). CM accounted for a significantly higher proportion of causative foods in physician-diagnosed FPIES while HE accounted for a significantly higher proportion of caregiver-reported FPIES (p < 0.05). Conclusion: A discrepancy was found in reports of the most common causative food between caregiver-reported and physician-diagnosed cases of FPIES. [ABSTRACT FROM AUTHOR]
