JAMA Intern Med :雷雨天前夕慢阻肺或哮喘发作增加!

2020-08-16 岱西 中国循环杂志

近日,一项美国研究发现,雷雨天暴发前夕,哮喘和慢阻肺等呼吸道疾病急诊患者人数明显增加。研究者回顾医保数据,就1999~2012年间65岁以上有呼吸疾病者前往急诊就诊情况和当时天气情况进行了分析。

近日,一项美国研究发现,雷雨天暴发前夕,哮喘和慢阻肺等呼吸道疾病急诊患者人数明显增加。

细挖一下,这也不少见。早在1983年,就有英国研究对此首次描述;而1987年和2016年澳大利亚再次报告。

当时,有学者怀疑是空气中花粉作怪,认为暴风将花粉粒卷入云层,进而花粉粒又分裂成更细的颗粒,最后又随气流返回地面而诱发人群哮喘发作。

还有研究分析认为,雷雨天是真菌、霉菌等过敏原繁殖的“温床”,加上低气压,空气中过敏原浓度就会有所升高,进而诱发哮喘。

不过目前尚无清晰解释。

这项研究中,研究者回顾医保数据,就1999~2012年间65岁以上有呼吸疾病者前往急诊就诊情况和当时天气情况进行了分析。

结果发现,雷雨天暴发前,慢阻肺、哮喘等呼吸系统疾病就诊出现高峰。估计全美约增加了5.2万例急诊就诊。

不过,他们认为,花粉也许并非致病原因,而气压变化所致气流变化导致大气可吸入颗粒物增加或是其中缘由。

研究者还发现,这些雷雨天前夕就诊的老年患者多体温升高,这可能是由于肺部吸入颗粒物反应所致。

研究者指出,随着全球变暖,雷雨天会越来越严重和频繁,老年人以及有呼吸系统疾病者或会受到较大影响。
