Patient characteristics
In total, sera from 101 peanut-sensitized patients (peanut-sIgE ≥ 0.1 kU/l) were analyzed. The median age of the patients at the time of blood drawing was 16 months (range: 5-24 months). 26 patients (25.7%) were ≤ 12 months of age. Nearly all patients (98%) suffered from eczema. A high proportion was sensitized to Ara h 1 (83.2%) and Ara h 2 (70.3%). Of 81 (80.2%) patients undergoing an OFC with peanut, 33 (40.7%) showed objective symptoms of an immediate type allergic reaction and were therefore proven to be allergic.
