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. Details on patient characteristics
are provided in table 1.
