Objectives

Narrative objectives1

Evaluating the tolerance induction ability of ultra low dose oral immunotherapy using individually adjusted safe-proven diluted allergen extracts for severe peanut and nut (walnut) allergy subjects whose only treatment has been an elimination diet because of severe adverse reactions to oral food challenges of the offending foods in mg units.

Assessment

Primary outcomes

the rate of the subjects who could have been administered a usual oral immunotherapy using peanut or nut(walnut) powder in mg unit during the test period.

Key secondary outcomes

1.oral challenge threshold changes of serially diluted allergen extracts; verified every month till 24 months after the research start.
2. oral challenge threshold changes of antigen powders in mg units.(every month)
3.threshold changes of skin prick tests of serially diluted allergen extracts.(every year)
4. changes of wheel size of skin prick tests of diluted allergen extracts.(
every year)
5. antigen specific IgE level change (every year)
6.Basophil Activation Test results on several diluted allergen extracts(before and after the study)
7.the rate of subjects who could intake allergen nut containing foods.
8.safety evaluation (the rate of adverse reactions at challenge phases in a clinic setting and maintenance phases at home)
