The Value Of The Helicobacter Pylori Stool Antigen Test In Patients With Peptic Ulcer Bleeding

Objective:To explore the diagnostic ability and influence of HpSA in patients with peptic ulcer bleeding.Methods:Collecting 116 patients with peptic ulcer bleeding which diagnosed by gastroscope at Baoding No.1 Central Hospital from 2017 to 2018.Hp was detected by histological result,HpSA and ¹³C-UBT.We analyzed the clinical value of HpSA.Results:Take histological result as diagnostic criteria,the sensitivity of HpSA was 91.1%（51/56）,the specificity was 83.3%（50/60）,the positive predictive was 83.6%（51/61）,the negative predictive was 90.9%（50/55）,and the accuracy was 87.1%（101/116）.the sensitivity of ¹³C-UBT was 51.8%（29/56）,the specificity was 86.7%（52/60）,the positive predictive was 78.4%（29/37）,the negative predictive was 65.8%（52/79）,and the accuracy was69.8%（81/116）.The consistency between HpSA and histological result was high,Kappa=0.742,and the consistency between ¹³C-UBT and histological result was poor,Kappa=0.389.Conclusion:HpSA is highly consistency with the diagnostic criteria,It is a reliable detection to diagnose Hp infection in patients with peptic ulcer bleeding.
