摘要
目的 探讨老年慢性萎缩性胃炎 (Chronicatrophicgastritis,CAG)患者血清胃泌素的变化及其与幽门螺杆菌感染之间的关系 ,将胃泌素作为血清学的诊断标志物 ,用于老年CAG的诊断。 方法  12 0例因消化不良行胃镜和活体组织病理检查的患者 ,根据病理结果分为正常组、胃炎组、轻度、中度和重度萎缩组共 5组。ELISA方法检测血清基础胃泌素、幽门螺杆菌IgG抗体和蛋白刺激后血清胃泌素。胃泌素增加量为刺激后胃泌素与基础胃泌素之差。 结果 幽门螺杆菌IgG抗体阳性 74例 ,其中CAG患者阳性 5 3例。血清基础胃泌素、刺激后胃泌素和胃泌素增加量与粘膜病变程度呈负相关。幽门螺杆菌感染可使CAG患者的基础胃泌素的水平升高。胃泌素增加量诊断CAG的受试者工作特征 (ROC)曲线下面积是 0 918( 95 %CI :0 871~ 0 96 5 ) ,临界值为 5 5 pg/ml,灵敏度和特异度分别为 89%和 84 %。 结论 血清胃泌素增加量可做为诊断CAG的敏感标志物 ,对老年人CAG初始筛选有一定意义 ,是内镜和组织活检的有效补充。
