J Allergy Clin Immunol:鼻腔内铅含量是过敏性鼻炎的加重的原因之一

空气污染物被质疑会影响过敏性鼻炎(AR)的病理状况。

空气污染物被质疑会影响过敏性鼻炎(AR)的病理状况。

最近,有研究人员在日本柳杉花粉中检测出铅(Pb)(375μg/kg)后,调查了鼻腔内接触Pb对AR症状的影响

研究人员从花粉季节前到季后,调查了44名日本柳杉花粉病患者和57名对照的花粉数量、主观症状和鼻腔上皮内膜液(ELF)中Pb的含量,并利用AR小鼠模型证实了鼻内暴露Pb对症状的影响。研究发现,在花粉季节期间,患者ELF中的Pb水平比对照组ELF中的Pb水平高40%以上,但在花粉季节前没有比对照高。ELF中的Pb水平与就诊前最近4天的花粉数量以及主观症状的评分呈正相关。鼻内暴露于Pb会使过敏小鼠的症状加重,表明Pb是一种加重因素。尽管鼻内挑战相同量的Pb,但暴露于Pb的过敏性小鼠ELF和鼻粘膜中的Pb水平均高于暴露于Pb的非过敏性小鼠。由于Pb暴露过敏小鼠鼻粘膜中Pb水平的增加在清洗鼻腔后有所下降,因此鼻粘膜表面的Pb(而非鼻粘膜内的Pb)可能是过敏小鼠ELF中Pb水平增加的一个来源。

主观症状与Pb水平之间的关系

最后,研究人员指出,部分来自花粉的鼻腔Pb含量的增加可能会加重AR的主观症状,表明Pb是AR的一种新型有害空气污染物
