Characteristics of children with food protein‐induced enterocolitis and allergic proctocolitis
Background:
The aim of this study was to determine and compare the clinical and laboratory features of food protein‐induced enterocolitis syndrome (FPIES) and food protein‐induced allergic proctocolitis (FPIAP), and to provide information about the short-term prognoses.
Method:
Children diagnosed with FPIES or FPIAP between 2010 and 2015 were enrolled in this study.
Results:
Overall, 64 infants (37 FPIAP, 27 FPIES) were evaluated, with the average age at the onset of symptoms being significantly lower in the patients with FPIAP than in the patients with FPIES (2 months [1‐3 months] versus 4 months [1.5‐6 months]; p = 0.043). Fifteen of the patients with FPIAP (40.5%) and six of the patients with FPIES (22.2%) were exclusively breast-fed at the time of the onset of symptoms. Cow's milk was the most frequent trigger (100% FPIAP, 74% FPIES); solid foods caused FPIES more frequently. Forty-eight of the 64 patients were followed up until at least 2 years of age, with the resolution rates being 91.3% for FPIAP and 60% for FPIES. The solid food‐induced cases of FPIES (27.3%) had a significantly lower rate of resolution than the liquid food‐induced FPIES (83.3%) (p = 0.003).
Conclusion:
Cow's milk is the most common trigger of both FPIAP and FPIES. The symptom onset age seemed to be earlier in FPIAP. The resolution age was similar, however, the recovery in FPIES may be later if the trigger food is solid. To our knowledge, this was the first clinical study to compare the clinical and laboratory characteristics of patients with FPIAP and FPIES.

Publication date: 01 January 2017
- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
