Emerging developments in the forefront of peanut oral immunotherapy.

ABSTRACT

PURPOSE OF REVIEW Despite the COVID-19 pandemic, progress continued in the field of peanut oral immunotherapy over the past 12 to 18 months. Of importance, the first oral immunotherapy product for the treatment of peanut allergy was approved by the US Food and Drug Administration in January 2020. RECENT FINDINGS: Suggested modifications to the practice of oral immunotherapy, some of which may have lasting impacts, were circulated as a result of the pandemic. New advances in pathophysiology, sustained unresponsiveness, quality of life, safety, and cost effectiveness were also published. SUMMARY: During 2020, COVID-19 influenced the daily practice of allergy and immunology, with peanut oral immunotherapy being no exception. However, clinicians now have a FDA-approved treatment option for peanut allergy in children, a welcome development for a difficult disease. Future research is needed to clarify several knowledge deficits surrounding the best use of peanut OIT.
