Clin Exp Allergy :饮用水中细菌量与过敏性疾病相关性研究

2020-04-24 AlexYang MedSci原创

饮用水处理能够减少微生物的接触。最近,有研究人员调查了是否饮用水中细菌的含量与过敏性疾病风险的变化相关。

饮用水处理能够减少微生物的接触。最近,有研究人员调查了是否饮用水中细菌的含量与过敏性疾病风险的变化相关。

研究包括了1110名学生,年龄在6-16岁,时间为2011年和2013年之间。研究发现,使用个体水井供水的儿童中,饮用水累积细菌含量更高(均值(IQR):6390 [4190-9550] vs 0[0-0]; P<0.0001),过敏性疾病终生患病率也显著更低(哮喘,过敏性皮肤炎(AD)和鼻炎分别为5.5% vs 2.3%, P=0.01; 14.4% vs 6.7%, P<0.001; 25.2% vs 15.1%, P<0.001)。与参照组相比(城市/公共供水),乡村个体水井供水儿童的哮喘,AD和鼻炎风险显著减少(OR [95% CI]: 0.14 [0.03,0.67], P=0.013; 0.20 [0.09,0.43], P<0.001; 0.17 [0.10,0.32], P<0.001)。研究人员在乡村/公共供水组中也观察到了保护作用,但是保护作用在乡村/个体水井供水儿童中最强。在定量分析中,过敏性疾病的风险随着1岁期间饮用水中细菌含量增加显著减少(喘息,AD和鼻炎分别为0.79 [0.70,0.88], P<0.001; 0.90 [0.83,0.99], P=0.025; 0.80 [0.74,0.86], P<0.001)。

最后,研究人员指出,饮用水中高共生菌含量对过敏性疾病具有预防作用。

病毒、细菌和基因突变,谁是你很大的敌人?

30亿~40亿年前,生命始祖——细胞诞生了。自此,生命向着多样化和复杂化演化。但病毒是个奇葩,它向简单化发展。病毒放弃它不需要的一切,只剩下蛋白质外壳及其里面的核酸。病毒就像海盗,“劫持”细胞,在宿主细胞中生存和繁衍。对生命来说,病毒仿佛一种生存压力。在这种压力之下,弱者淘汰,适者生存。为了对抗敌人,生命诞生了防卫系统——免疫系统。在病毒等多种病原体的刺激下,免疫系统不断进化。病毒还是“基因快递员
