Skin tests and laboratory parameters
More than half of the allergic population (n=50, 51%) had positive SPT results to various nuts and 38 (39%) had positive SPPT. MPD of SPT and SPPT to the respective nuts are represented in table 2 , as well as whole extract sIgE. Mean value of total IgE was 1860 U/mL (SD 1984, range 17-6314 U/mL).
Molecular components were obtained for 48 (49%) patients. The most frequent allergens were from LTP family, predominantly Pru p 3, for which 20 (42%) patients showed positivity. Subsequently, the most relevant was Ara h 9 (n=17, 35%), followed by Jug r 3 (n=16, 33%), Cor a 8 (n=12, 25%) and Tri a 14 (n=4, 8%). The 2S albumin family was the second most documented, namely Jug r 1 (n=18, 38%), Ara h 2 (n=13, 27%) and Ara h 6 (n=11, 23%).
