Pine nuts are the seeds of Pinus pinea. There are few reported cases of allergy to pine nut. We describe two young girls with anaphylaxis caused by small amounts of pine nuts. Specific IgE to pine nut was demonstrated by skin prick tests and RAST but no IgE to other nuts and pine pollen was detected. The patients had IgE against a pine nut protein band with apparent molecular weights of approximately 17 kDa that could be considered as the main allergen. Our patients were monosensitized to pine nut and the 17-kDa protein could be correlated with the severe clinical symptoms.
松子是欧洲赤松的种子。报告的松子过敏病例很少。我们描述了两名因少量松子引起过敏反应的年轻女孩。通过皮肤点刺试验和放射变应原吸附试验证实了对松子的特异性IgE，但未检测到对其他坚果和松花粉的IgE。患者体内存在针对一条表观分子量约为17 kDa的松子蛋白条带的IgE，该条带可被视为主要过敏原。我们的患者对松子单敏，且17-kDa蛋白可能与严重的临床症状相关。
