In children allergic to egg, oral immunotherapy (OIT) with egg may accelerate that the children grow out of the food allergy.

Children than have a positive oral food provocation with egg with a low threshold, will be offered to start OIT. This means that the child have to ingest a small amount of egg every day.

Once a year, the child will undergo a new oral food provocation to investigate if the child is still allergic to egg or not.

The age of the children at time of this acquired tolerance will be compared with a historical cohort of children with egg allergy.

The aim of the study is to investigate if OIT with egg white can accelerate tolerance to egg in infants with provocation-verified allergy to egg and with a low threshold.

The study is non-randomised. Children fulfilling the inclusion criteria will be offered OIT. The children will undergo an oral provocation once a year to detect development of tolerance to egg. Age at tolerance acquisition will be compared with a histical cohort of aged-matched children with allergy to egg and with a similar threshold at the diagnostic provocation

Inclusion Criteria:

• positive specific IgE to egg
• positive oral provocation for egg
• low threshold

Exclusion Criteria:

• uncontrolled astham treatment with biologics or immunsupressive drugs treatment with antihistamines
