Clinical pearls and pitfalls: peanut allergy.
A case of pediatric peanut allergy is presented. Pathophysiology, clinical characteristics, diagnostic test, case management, and natural history are reviewed. Clinical Pearls and Pitfalls include: (1) About 20% of young infants will outgrow peanut allergy, especially if IgE levels measured by ImmunoCAP RAST are less than SkU/L. (2) Cases of resensitization have been documented after negative peanut oral challenges. (3) Only a negative food challenge can provide convincing evidence that the patient has outgrown his or her peanut allergy.
