Study results suggest that graded challenges can be performed safely in two steps with the addition of placebo to reduce false-positive reactions in patients with multiple drug allergies.


Researchers have devised a modified, accelerated allergen immunotherapy (AIT) protocol (MERIT) that combines rapid and safe build-up to the maintenance AIT dose. Most systemic reactions seen with use of MERIT appear to be mild and rapidly reversed with treatment.


Study results indicate that African-American patients with asthma appear to exhibit greater eosinophilic airway inflammation than their Caucasian cohorts, possibly explaining the greater asthma burden seen among the former population.

This course discusses a study that sought to determine improvement of which symptoms of chronic rhinosinusitis (CRS) would be associated with the greatest improvements of quality of life (QOL) and, likewise, which worsening symptoms of CRS would be associated with the most severe worsening of QOL.


This course discusses a study that evaluated critical inputs associated with the cost-effectiveness of epicutaneous peanut immunotherapy and peanut oral immunotherapy from a societal perspective.

This course discusses a study that sought to determine the association of rheumatoid arthritis with asthma and allergies after controlling for allergic diseases, urban environment, and passive smoke.


This course discusses a study that collected nationally representative estimates of the distribution, severity, and key factors associated with adult food allergies.


This course discusses the key findings of five studies presented at the 2019 Annual Scientific Meeting of the American College of Allergy, Asthma and Immunology.

This course discusses a study that explored whether maternal allergen-specific immunoglobulin G could protect offspring from immunoglobulin E sensitization.
