(Grade B)The degree to which egg has been processed for early introduction seems to affect clinical outcomes with raw egg powders causing more complications due to increased allergenicity. (Grade C)Pre-testing with either SPT or specific serum markers (e.g., sIgE) in high-risk infants can inform the clinician whether clinical supervision of early egg introduction may be useful. (Grade C)A 4-year-old infant comes into allergy clinic with her parents who say that after eating eggs and egg-containing foods she develops a ‘nettle sting’ rash around the mouth. This usually happens within an hour of eating. After an oral food challenge, an egg allergy is diagnosed. At a follow-up appointment, the parents ask you whether this could have somehow have been prevented. You look into whether early dietary introduction of egg would have played a role.In children (population), does early introduction of egg (intervention) compared with later introduction (comparison) prevent the development of egg allergy (outcome)?All searches were all performed on 17 February 2021.Cochrane Library searched: ‘egg allergy prevention’ and ‘early introduction’; 26 results, none relevant.
