目的

探讨胃食管反流病(gastroesophageal reflux disease,GERD)与阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAHS)的关系。

方法

分析43例怀疑咽喉反流病患者的高精度食管压力检测、24h食管双极阻抗pH监测、便携式多道睡眠监测数据,根据各检测结果进行分组,比较组间各测量指标差异,研究两疾病的相互关系。

结果

全体受试者中,可诊为GERD的14例(32.6%),可诊为OSAHS的26例(60.5%),同时患有OSAHS和GERD者10例,占OSAHS患者人数的38.5%,占GERD患病人数的71.4%。在仅患有OSAHS组、仅患有GERD组、同时患有GERD和OSAHS组以及阴性对照组之间,体质量指数(BMI)和下食管括约肌(10weresophagealsphincter,LES)残余压差异有统计学意义(P值均<0.05),但未发现LES残余压与两疾病严重程度的线性相关关系。在OSAHS患者中,呼吸暂停低通气指数(AHI)与DeMeester评分(r=0.457)、远端食管酸暴露时间百分比(r=0.491)呈正相关趋势(P值均<0.05)。在GERD患者中,未发现反流指标与睡眠指标和食管功能指标的线性相关关系。同时患有OSAHS和GERD组内未见反流指标、睡眠指标、食管功能指标的线性相关关系(P值均>0.05)。

结论

GERD与OSAHS在发病率、疾病的严重程度方面有一定的相互影响,反酸可能加重OSAHS患者的病情,两种疾病可能在食管功能,特别是在LSE肌张力的调节上有一定的相关关系。
