Brief summary
Non-IgE-mediated gastrointestinal food allergies (non-IgE-GIFA) are an evolving web of clinical conditions characterized by subacute and/or chronic symptoms and include food protein-induced enterocolitis syndrome (FPIES), food protein-induced enteropathy (FPE), food protein-induced allergic proctocolitis (FPIAP), and food protein-induced allergic dysmotility disorders (gastroesophageal reflux disease (GERD), colic and constipation) (FPIMD). Despite the prevalence and clinical impact of these conditions, the pathogenesis as well as the natural history and the best management of these disorders are still poorly defined. These limitations could be responsible for diagnostic delays and errors, and suboptimal clinical management. We aim to evaluate clinical features, natural course and pathophysiology of non-IgE-GIFA in the pediatric age.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of clinical features and disease course of non-IgE mediated food allergies in children | After 72 months from the study start | Rate of pts affected by FPIES, FPE, FPIAP, FPIMD; diagnostic delay; disease duration, rate of pts with mono vs poli food allergies; main antigens responsible for the diseases; occurrence of atopic dermatitis before food allergy onset; results of allergy screening tests; occurrence of atopic march |
| Evaluation of clinical features of non-IgE mediated food allergies in children | After 72 months from the study start | Dietary management and Nutritional status (weight and height will be combined to report BMI z-score) |
Secondary
| Measure | Time frame | Description |
