非特应性哮喘及反流患儿支气管高反应性:抗反流治疗的作用
2009/12/15
方法:30名患持续性哮喘的非特应性儿童入选本研究。采用持续食管pH值监测诊断GERD,乙酰甲胆碱激发试验(MCT)作为BHR的标志物,于抗GERD治疗前及2年后检测BHR。
结果:21名患儿存在GERD(A组),15名患儿MCT阳性,提示存在BHR。9名无GERD的患儿(B组)中,5名MCT阳性。2年后再次检测,A组内15名患儿中的11名,以及B组内5名患儿中的3名BHR检测为阴性。与B组患儿相比, A组患儿的哮喘相关用药较少,哮喘恶化次数出现较少。
结论:哮喘及GERD患儿中的BHR较为常见,针对GERD治疗后BHR能得到显著改善。

Bronchial hyperreactivity in non-atopic children with asthma and
reflux: Effect of anti-reflux treatment.
Khoshoo V, Mohnot S, Haydel R Jr, Saturno E, Edell D, Kobernick A.
INTRODUCTION: The prevalence of bronchial hyperreactivity (BHR) or the effect of anti-reflux treatment on BHR in children with asthma and gastroesophageal reflux disease (GERD) is not known.
METHODS: Thirty non-atopic children with persistent asthma were studied. Extended esophageal pH monitoring was used to diagnose GERD and methacholine challenge test (MCT) was used as a marker of BHR and performed before and 2 years after anti-GERD treatment.
RESULTS: Of the 21 patients positive for GERD (group A), 15 had positive MCT suggesting BHR. Of the 9 patients negative for GERD (group B), 5 had positive MCT. On repeat testing 2 years later, 11/15 group A patients and 3/5 group B patients tested negative for BHR. Group A patients were receiving fewer asthma medications and experienced fewer exacerbations than Group B patients.
CONCLUSIONS: BHR is prevalent in children with asthma and GERD and improves with anti-GERD treatment.
