Is Ara h 2 indeed the best predictor for peanut allergy in Dutch children?

Background: Specific immunoglobulin E to Ara h 2 (sIgE to Ara h 2) is described as an upcoming predicting factor for diagnosing peanut allergy in children. The gold standard for diagnosing peanut allergy is a double blind placebo controlled food challenge, however this is time consuming and potentially harmful. We investigate Ara h 2 as a preliminary less invasive diagnostic tool for diagnosing peanut allergy in a general population of peanut sensitized children.

Case Description: We present a 6-week-old, formula-fed girl with frequent vomiting, diarrhoea and failure to thrive.
