Peanut Sensitization Profiles in Italian Children and Adolescents with Specific IgE to Peanuts

Table 2

Rates of sensitization against one of the five peanuts’ molecular components (rAra h 1, 2, 3, 8, and 9) in a population of 48 children and adolescents (median age: 8 years; range: 2–16) with documented peanut sensitization (sIgE > 1 kUA/L). Patients sensitized against one allergenic component were defined as “monosensitized,” whereas those sensitized to more than one of the five peanuts’ allergens were defined as “polysensitized.” Patients were categorized according to the tolerance status against peanuts.
