IGHE and skin disorder: Figure 4 shows the prevalences and IgE levels specific for the recombinant allergen molecules for different types of symptoms. No relevant association of IgE sensitization to a particular allergen and certain symptoms was found. We only noted that none of the six patients with dermatitis reacted with Sal k 2, Sal k 3, and the cross-reactive Phl p 7 allergen, whereas other allergens were recognized (Figure 4).
