Abstract
The present study tested the hypothesis that a pan-allergen sensitization may affect the sensitization pattern. For this reason, 22 sensitization pattern allergens (SPA), common in Genoa (Italy), were selected for analyses. Successively, five of them, such as Pru p 3 as representative for LTP family, Bet v 1 and Pru p 1 for PR-10, and Bet v 2 and Pru p 4 for Profilin, were used as target allergens (TA). This retrospective study included 1059 subjects, (396 males and 663 females, mean age 42.8 years). The current study showed that sensitization to a pan-allergen entails higher odds to have other sensitizations. In addition, the co-sensitization pattern depends on the basis of the sensitizing pan-allergen family. LTP-sensitization is strongly associated with peanut sensitization, PR10 and profiling sensitization with hazelnut positivity.This study shows that a pan-allergen sensitization is frequently associated with co-sensitizations and the sensitization pattern depends on the sensitizing pan-allergen.
