Literature review: Food allergy - Twitter summary from 2014 #ACAAI meeting

Dr Vivian Hernandez-Trujillo discussed Food and Additives Allergy.

Sustained unresponsiveness to peanut in subjects who have completed peanut oral IT - JACI 133: 468. First study to show sustained unresponsiveness (4 weeks) after peanut OIT was stopped.

Peanut, milk and wheat intake during pregnancy is associated with reduced allergy and asthma in children - JACI 133: 1373. Maternal peanut intake in 1st trimester was linked to almost 50% reduction in odds childhood peanut allergy. Maternal milk intake in 1st trimester was linked to 15% decreased odds childhood asthma and allergic rhinitis. Maternal wheat intake in 2nd trimester was associated with "decreased atopic dermatitis". A window of exposure during early life may exist where food tolerance develops.

Skin prick test (SPT) responses and sIgE levels as predictors of peanut, egg and sesame allergy in infants - JACI 2013; 132: 874. SPT was more precise than sIgE at predicting sesame, egg and peanut allergy in infants with NO history of reactions. No SPT threshold exists for 95% PPV for BAKED egg. No sIgE threshold exists for 95% PPV sesame allergy or baked egg allergy.

IgE-targeted testing vs. 6 food elimination diets for EoE - Allergy 69:936. Serum specific IgE were better at detecting offending agent than percutaneous testing (prick and atopy patch). 100% of patients with positive milk sIgE had reactivation of disease at time of reintroduction. A remission occurred in almost 3/4 pts with sIgE-ED, comparable to six food elimination diet. This was a study of adults with EoE.

Several allergists did a great job posting updates from the 2014 meeting of the #ACAAI. I used the website “All My Tweets” to review the tweets. For comparison, here are the tweets from previous #ACAAI meetings (scroll down the page for the past years):
