胃非霍奇金淋巴瘤患者幽门螺杆菌检测方法比较

Comparison of two methods for Helicobacter Pylori detection

目的比较尿素氮呼气试验和粪便抗原检测胃非霍奇金淋巴瘤患者幽门螺杆菌感染的准确性。方法以病理检测结果为对照,对25例确诊胃非霍奇金淋巴瘤患者分别进行尿素氮呼气试验和粪便抗原检测幽门螺杆菌,比较两者检出的准确度。结果粪便抗原检测敏感性81.3%,特异性88.9%,阳性预测值92.9%,阴性预测值72.7%,准确度84%。尿素氮呼气试验敏感度93.8%,特异度100%,阳性预测值100%,阴性预测值90%,准确度:96%。结论尿素氮呼气试验对幽门螺杆菌检测的准确性高于粪便抗原检测。

Objective To compare the accuracy of urea breath test （UBT） and stool antigen detection of Helicobacter pylori（HP） in patients with non-Hodgkin＇s gastric lymphoma. Methods UBT and stool antigen detection were performed to detect HP in 25 patients with non-Hodgkin＇s gastric lymphoma using pathological results as controls. The accuracy of the two methods for PH detection was compared. Results The sensitivity, specificity, positive and negative predictive value, and accuracy of stool antigen detection for HP were 81.3%, 88.9%, 92.9%, 72.7% and 84%, respectively. The sensitivity, specificity, positive and negative predictive value, and accuracy of UBT for PH detection were 93.8%, 100%, 100%, 90% and 96%, respectively. Conclusion The accuracy of UBT is better than stool antigen detection for the detection of HP.
