Abstract

Purpose of review: Because of the paucity of reports and variability in the diagnostic criteria utilized, little is known regarding the natural outcome of patients with food protein-induced enterocolitis syndrome (FPIES). Data extracted from referenced manuscripts, as well as allergists' unpublished observations from across the globe, were used to form a cohesive opinion regarding its natural outcome. Recent findings: All authors concur that there is a generally high rate of recovery for FPIES. The most common foods causing FPIES are milk and soy. Depending upon which study is analyzed, by the age of 3-5 years, approximately 90% of patients recover from their disease. Recovery from FPIES to solid foods, occurs at a later age, but may reflect a later stage of introduction of the food into the diet. An important clinical outcome, although not common, is a shift from FPIES food hypersensitivity to an IgE-mediated food allergy. This necessitates a change in the oral food challenge protocol, if IgE-mediated sensitization is detected. Summary: Over the past several years, there has been an increasing awareness of FPIES. This knowledge should lead to a more timely diagnosis and should reassure parents and practitioners alike regarding its favorable course.
