Polyphenol oxidase cross-linking enhances whey protein-induced systemic food allergy by regulating miRNA in CD4 T cells.

Whey protein (WP) contains two major allergenic proteins, α-lactalbumin and β-lactoglobulin, which significantly impact its incorporation and application in food products. Current research primarily focuses on the dynamic changes in allergenicity during the processing of individual protein components. To simulate realistic conditions in food processing, this study aims to investigate the effect of polyphenol oxidase cross-linking on the allergenicity of complex protein matrices.

Among the possible adverse reactions to gluten, celiac disease, non-celiac gluten sensitivity, and IgE-mediated wheat allergy have been classically described. A non-IgE-mediated reaction similar to food protein-induced enterocolitis syndrome (FPIES) after inadvertent gluten ingestion in a celiac patient was recently reported. We present three children affected by celiac disease with exquisite control, including appropriate adherence to an exclusion diet, who suffered a severe adverse food reaction after unappreciated outdoor ingestion of gluten, meeting the criteria for a definitive diagnosis of FPIES.

Background: Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated allergy without known biomarkers. We aimed to compare fecal biomarkers related to gut inflammation and immunity in children with FPIES, with resolved FPIES (tolerant), and in matched controls.
Methods: Stools were collected from FPIES children on elimination diet, before and after an oral food challenge (OFC) performed to assess their natural tolerance, at the end of a follow-up in tolerant FPIES children, and in matched controls (1:1 ratio).

Non-immunoglobulin E (IgE)-mediated food allergies are characterized by delayed gastrointestinal (GI) manifestations that occur after exposure to an inciting food protein; they include food protein-induced allergic proctocolitis (FPIAP), food protein-induced enteropathy (FPE), and food protein-induced enterocolitis syndrome (FPIES). Although the exact mechanisms underlying these disorders are not well understood, non-IgE-mediated food allergies likely represent a spectrum of disease with shared pathophysiological processes. Typically, these non-IgE-mediated food allergies begin in infancy or early childhood, although FPIES can present across the lifespan, with increasing reports in adults in recent years.
