A study to test a new model of care for the prevention of tree nut allergy for infants with peanut allergy. The TreEat study compares a multi-nut oral food challenge versus home introduction of single tree nuts.

  • aged between 4 months and 11 months of age
  • have confirmed peanut allergy with SPT (≥3mm) or sIgE (>0.35kU/L)

Infants will be ineligible if:

  • Any history of severe food induced anaphylaxis. (2 doses of IM adrenaline)
  • Pre-existing tree nut allergy (parent-reported)
  • Any tree nut already tolerated (ingestion on >3 occasions without reaction of around 1 teaspoon)
  • SPT or sIgE performed to any tree nuts
  • Not commenced or unable to eat solid food
  • Prescribed beta-blocker medication
