2078- Immunotherapy – 2078. Allergen-specific oral immunotherapy for peanut allergy: a Cochrane systematic review

Results We identified one RCT with 28 children age 1-16 years (19 in the OIT group and nine in the placebo group). Because of allergic side-effects, three children were withdrawn from the OIT group early in the study. The remaining 16 participants in the OIT group completed the study and ingested a maximum cumulative dose (MCD) of 5000 mg (≈20 peanuts). All 9 participants in the placebo group completed the study, but ingested an MCD of only 280 mg (range, 0-1900 mg, P<0.001). Children in the OIT group had reductions in peanut-specific skin prick tests (P<0.001), IL-5 (P=0.01), and IL-13 (P=0.02), and increases in peanut-specific IgG4 (P<0.01) and T reg cells. Nine children (47%) of the 19 in the OIT group experienced side-effects and two of them required epinephrine treatment.
