老年社区获得性肺炎与胃食管反流

目的本研究旨在通过对老年肺炎患者24h食管pH监测,探讨胃食管反流(gastroesophageal reflus,GER)在老年肺炎发病机制中的作用.方法选择31例老年社区获得性肺炎患者及30例非肺炎患者进行24h食管pH监测,计算酸反流得分,以12.70作为酸反流得分的正常界限.结果 31例老年肺炎患者平均酸反流得分34.91,对照组平均酸反流得分5.95,与对照组比较,有显著性差异(P＜0.01).肺炎患者25例存在胃食管反流,占80.6%(25/31),其中仅5例有胃食管反流症状,占20.0%(5/25).结论胃食管反流可能是老年肺炎的重要发病机制之一.老年肺炎患者胃食管反流多无典型症状.

Community-acquired pneumonia in the aged and gastroesophageal reflus

Objective To research the role of gastroesophageal reflux in pathogenesis of the aged community-acquired pneumonia by using 24h esophageal pH monitory.Methods Thirty-one patients with community-acquired pneumonia and 30 patients with non-pneumonia in the aged enrolled were tested by using 24h esophageal pH monitoring. Score of acid reflux was calculated.Results The score of acid reflux in 31 patients with community-acquired pneumonia was 34.91.The score of acid reflux of patients in control group was 5.95.There was significant difference between two groups (P<0.01). Twenty-five patients with pneumonia had gastroesophageal reflux,account for 80.6%(25/31), only 5 patients had typical symptoms of gastroesophageal reflux.Conclusion GER may be one of the important pathogenesis of community-acquired pneumonia in the aged. The patients with GER in the aged with pneumonia have not mostly typical symptoms.
