The safety of peanut oral immunotherapy in peanut-allergic subjects in a single-center trial

Int Arch Allergy Immunol. 2012;159(2):179-82. doi: 10.1159/000336391. Epub 2012 Jun 1.

Abstract

Background: Peanut allergy is the leading cause of food-related anaphylaxis, and accidental exposures are common. Oral immunotherapy (OIT) has been posited as a potential treatment.

Methods: Patients aged 3-65 years with peanut-specific IgE ≥7 kU/l and/or a positive skin prick test with a history of an allergic reaction to peanut were recruited to undergo an OIT protocol. All adverse reactions were recorded by research staff or patients in real time.

Results: Twenty-four patients received 6,662 doses. Symptoms were mostly mild (84%), and only 3 severe gastrointestinal reactions required the administration of epinephrine. Abdominal pain was the most common reaction, followed by oropharyngeal and lip pruritus. Respiratory symptoms were rare.

Conclusions: In this trial of OIT in adults and children, most reactions were mild.
