A different starting line for allergic march: food protein-induced allergic proctocolitis.

Objective: The aim of this study is to investigate the long-term prognosis of food protein--induced allergic proctocolitis (FPIAP) patients, the risk of developing both allergic and gastrointestinal diseases, and to evaluate whether it leads to allergic march.

Methods: A total of 149 children who were diagnosed with FPIAP and developed tolerance at least 5 years prior to the study and 41 children (with no history of food allergy) as a control group were enrolled. Both groups were re-evaluated for allergic diseases as well as gastrointestinal disorders.

Evaluation of the Clinical Characteristics of Patients with Food Protein-Induced Enterocolitis Syndrome: A Multicenter Study.

Introduction: Food protein-induced enterocolitis syndrome (FPIES) is a rare non-IgE, cell-mediated food allergy disorder. We aimed to report the demographic characteristics, clinical features, and management of pediatric patients with FPIES.

Methods: This retrospective study included all children diagnosed with FPIES at the pediatric allergy departments of the participating twelve study centers from January 2015 to November 2020.
