目的探讨老年食欲不振患者幽门螺旋杆菌(HP)感染与胃排空的相关性。方法采用胶体金法和13C-辛酸呼气试验法对69例老年食欲不振患者,进行HP检测和胃排空检测。结果 69例患者中幽门螺旋杆菌阳性31例,阴性38例,阳性感染率为44.9%。HP阳性组和阴性组胃半排空时间分别为(244.5min±35.6min和232.4min±36.7min),差异无统计学意义。结论幽门螺旋杆菌感染可能不是导致老年食欲不振的主要因素,且幽门螺旋杆菌感染与胃排空无相关性。
Objective To investigate the correlation between Helicobacter pylori (HP) infection and gastric emptying in elderly patients with loss of appetite. Methods Colloidal gold method and 13C-octanoic acid breath test for 69 elderly patients with loss of appetite, HP detection and gastric emptying detection. Results Among the 69 patients, 31 were H. pylori positive and 38 were negative, the positive rate was 44.9%. The gastric half-emptying time was (244.5min ± 35.6min and 232.4min ± 36.7min) in HP-positive and -negative groups, respectively, with no significant difference. Conclusion Helicobacter pylori infection may not be the main cause of senile loss of appetite, and there is no correlation between H. pylori infection and gastric emptying.
