    Abstract:
    PURPOSE: Evaluation of the relationships between foods and pollen allergens in oral allergy syndrome (OAS). METHODS: Serous level of specific IgE against recombinant peach allergens (rPru p 1, rPru p 3 and rPru p 4) in 17 peach OAS patients were examined by Pharmacia CAP RASTsystem. RESULTS: In 17 pollinosis patients, the number of patients positive to peach, rPru p 1, rPru p 4 and rPru p 3 RAST were 13 (76%), 14 (82%), 6 (35%) and 0 (0%), respectively. The RAST value of rPru p 1 was significantly correlated with that of natural birch pollen extract (r=0.745, p=0.0003), but not with that of mugwort pollen extract. The RAST value of rPru p 4 was significantly correlated with that of mugwort pollen extract (r=0.602, p=0.0092), but not with that of natural birch pollen extract. CONCLUSION: Concerning to peach OAS, the most important cross-reactive antigen is Pru p 1 in birch pollinosis, and is Pru p 4 in mugwort pollinosis.
