Background: Data on the prevalence and clinical course of food protein-induced enterocolitis syndrome (FPIES) vary between populations and according to the culprit food. Objective: To evaluate the incidence, clinical characteristics, and remission patterns of FPIES among children in a Greek pediatric allergy referral center. Methods: We retrospectively studied children with acute FPIES. Data on age, sex, type of reaction, the implicated food, and oral food challenge (OFC) outcomes at baseline and upon reevaluation were analyzed. Results: Between October 2010 and March 2017, 72 (38 males) out of 15,114 subjects who had been referred to our department due to any reported allergic symptoms were diagnosed with acute FPIES. The most commonly implicated foods were cow's milk (CM) (45.8%), fish (34.7%), rice (9.7%), egg (6.9%), and chicken (2.8%). The mean age at diagnosis was 7.1/19.3/9.1/18.7/8.7 months for those with CM/fish/rice/egg/chicken FPIES, respectively. Sixty-nine OFCs were performed, of which 8 were diagnostic and 61 for tolerance evaluation. The type of culprit food was significantly associated with the outcome of the tolerance OFCs. OFCs to fish resulted positive at a significantly higher rate (12/22; 54.5%) than OFCs to CM (4/29; 13.7%), rice (1/5; 20%), egg (0/3; 0%), and chicken (0/2; 0%) (p = 0.01). The time period between diagnosis and tolerance acquisition was prolonged in the fish FPIES cases (74.8 months; 95% CI: 57.9-91.6) compared to that with other foods such as CM (20.7 months; 95% CI: 17.3-24.1), rice (31.8 months; 95% CI: 21.9-41.7), and egg (24.3 months; 95% CI: 10.7-37.9), as shown in a Kaplan-Meier analysis (log-rank, p < 0.001). When the fish FPIES children were assessed for tolerance, OFCs were significantly more often positive than in CM FPIES children (52 vs. 18.1%; p = 0.03), despite the fact that the children were challenged at an older age (fish: 70.4 months, 95% CI: 58.3-82.5, vs. CM: 26.57 months, 95% CI: 21.1-32, p < 0.001). Conclusions: Acute FPIES had a low incidence in our population. CM and fish were the two most frequent elicitors. Significantly delayed presentation and prolonged remission was noted for FPIES caused by fish. © 2019 S. Karger AG, Basel. Copyright: All rights reserved.
