A systematic review of food protein-induced enterocolitis syndrome from the last 40 years

Ann Allergy Asthma Immunol. 2017 Apr;118(4):411-418. doi: 10.1016/j.anai.2017.02.005.

Abstract

Objective: To provide a complete, exhaustive summary of current literature relevant to food protein-induced enterocolitis syndrome (FPIES).

Data sources: Data have been extracted from PubMed and Science Direct databases.

Study selections: Following the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, a literature search for peer-reviewed journal articles in English through January 1975 with updates through October 2016 was conducted. Relevant publications were reviewed that included pediatric and adult populations. Information on the study design, sample, intervention, comparators, outcome, timeframe, and risk of bias were abstracted for each article.

Results: Of 135 reviewed reports, 52 were included in this systematic review. In accordance with the age at onset, clinical features, and offending foods, it is possible to distiguish different types of FPIES. An immune systemic involvement can occur in patients with FPIES. In addition to the most common causative foods (cow's milk, soy, and rice), any food can potentially cause FPIES. Although specific diagnostic tests are not available, open food challenge remains the gold standard for FPIES diagnosis. Moreover, because of the lack of randomized clinical trials and of use of different adopted methods, confounding factors might mask critical findings, leading to poor knowledge of this pleiotropic clinical entity.

Conclusion: Multicenter studies are needed to better develop an evidence-based approach to pathophysiology, prevalence, diagnosis, and natural history of the disease.
