【摘要】：目的:探討北京地區(qū)樹(shù)木花粉的致敏特點(diǎn),并分析其與氣傳花粉的關(guān)系。方法:將2017年1~7月份變態(tài)反應(yīng)科就診的2 521例過(guò)敏性疾病患者納入研究,均接受8種樹(shù)木花粉變應(yīng)原點(diǎn)刺試驗(yàn)(SPT)。結(jié)果:(1)樹(shù)木花粉SPT陽(yáng)性率為49.3%(1 244/2 521)。男性致敏率高于女性(56.4%vs 45.0%,P0.01)。兒童組花粉致敏陽(yáng)性率顯著高于成人組(55.9%vs 48.6%,P0.05)。樹(shù)木花粉致敏趨向于多重致敏,≥3種樹(shù)木花粉陽(yáng)性率為26.3%,占總陽(yáng)性人群的53.3%。(2)樹(shù)木花粉致敏的陽(yáng)性率呈現(xiàn)典型的季節(jié)高峰,3月份陽(yáng)性率最高(62.2%),其次為5月份(52.1%),最低為1月份(27.9%)。花粉致敏陽(yáng)性率與空氣中花粉總量高度相關(guān)(r=0.929,P0.01)。(3)圓柏花粉點(diǎn)刺陽(yáng)性率最高(34.6%),其次為楊樹(shù)(21.3%),槐樹(shù)(13.3%)。不同花粉的致敏率和空氣中的含量高度相關(guān)(r=0.714,P0.05)。結(jié)論:北京地區(qū)主要致敏樹(shù)種為圓柏。春季樹(shù)木花粉致敏呈現(xiàn)季節(jié)性,3月份為致敏高峰期。春季樹(shù)木花粉致敏率與空氣中的播散量有關(guān)。
[Abstract]:Objective: to investigate the sensitizing characteristics of tree pollen in Beijing area, and to analyze its relationship with airborne pollen. Methods: a total of 2 521 patients with allergic diseases were enrolled in the study in 2017 and July. The results showed that the SPT positive rate of pollen was 49.3% (1 244/2 521). The sensitizing rate of male was higher than that of female (56.4 vs 45.0%). The positive rate of pollen sensitization in children was significantly higher than that in adults (55.9 vs 48.6P0.05). The positive rate of pollen sensitization of trees 鈮，
