The longitudinal impact of probiotic and peanut oral immunotherapy on health-related quality of life.

Probiotic and peanut oral immunotherapy has a sustained beneficial effect on psychosocial impact of food allergy at 3 and 12 months after end-of-treatment. Treatment was not associated with reduced HRQL relative to baseline in either PPOIT or placebo groups, indicating that PPOIT was well tolerated and psychological well-being was not negatively impacted. Improved HRQL was specifically associated with acquisition of sustained unresponsiveness.
