Example: Clinical efficacy and immune regulation with peanut oral immunotherapy. Jones SM et al. J Allergy Clin Immunol. 2009 Jul 2.
Oral immunotherapy (OIT) successfully induced desensitization in peanut allergy. Can OIT induce tolerance too?
Desensitization is an increase in threshold of ingested food antigen needed to cause allergic symptoms (achieved w OIT).
Tolerance is the induction of long-term immunologic changes with the ability to ingest food without symptoms and WITHOUT ongoing THERAPY.
The place of oral desensitization in the practice of allergy at this time is in flux - see why: http://goo.gl/gNKLD
"Sustained Unresponsiveness" is presently the preferred term to describe patients who were on OIT, stopped and had no reactions at that point

Therapies for peanut allergy: Sustained oral tolerance over desensitization is the goal, we are not there yet. http://goo.gl/mXsyt
Peanut oral immunotherapy (20 peanuts) induces desensitization, however questions about long-term tolerance remain. JACI, 2011.
