Abstract (provisional)
Background Rush oral immunotherapy (OIT) combined with omalizumab (OMB) has been reported to be an effective and safe treatment for severe milk allergies. However, no report has described long-term follow-up observations after OMB discontinuation. The purpose of this case report was to evaluate the safety and efficacy of rush OIT in combination with OMB during a long period of treatment. Case presentation A 5-year-old boy presented with a past history of two severe episodes of anaphylaxis (at the age of 2 and 3 years) after consuming small amounts of cow’s milk (CM).
