Abstract |
The role of specific IgA ( sIgA) in oral immunotherapy (OIT) and natural tolerance to foods is poorly understood. We aimed to study serum sIgA in induced and natural tolerance to egg. Children aged 5-16 years diagnosed with IgE-mediated egg allergy were recruited. After egg challenge, patients were classified as transient ( TEA) or persistent (PEA) egg-allergic. PEA children were further divided into oral immunotherapy (PEA-OIT) or egg avoidance (PEA-EA). Allergy/tolerance was reassessed 9-12 months later (T1) in PEA-EA. Serum sIgA to ovalbumin and ovomucoid were determined at inclusion in all patients and repeated in PEA at T1. 21 TEA and 52 PEA children were recruited (28 PEA-OIT, 24 PEA-EA). Serum sIgA remained unchanged after OIT. TEA and PEA had similar serum sIgA. No specific trend on serum sIgA was observed in five PEA-EA who developed natural tolerance over follow-up. Thus, serum sIgA seems not to be associated with induced or natural egg tolerance.
