摘要:
目的:探讨 13C 呼气试验(13C-UBT)检测幽门螺杆菌(Hp)感染的临床应用价值。方法 选取 180 例患者,其中慢性胃炎、消化性溃疡、胃癌各 60 例,每例患者均行 13C 呼气试验、快速尿素酶试验(RUT)、特殊病理 HE 染色,并以 RUT 和 HE 染色结果阳性作为本试验中 Hp 感染的“金标准”,评价 13C 呼气试验的临床应用价值。结果 本研究“金标准”中阳性 98 例,13C-UBT 检测阳性 94 例,阴性 4 例;“金标准”阴性 82 例,13C-UBT 检测阴性 79 例,阳性 3 例。13C-UBT 检测幽门螺杆菌感染的敏感度为 95.9%,特异性为 96.3%,准确性为 96.1%,阳性预测值为 96.9%,阴性预测值为 95.2%。结论 13C-UBT 具有较高的敏感性和特异性,是一种非侵入性检查,可以简便可靠地诊断幽门螺杆菌感染,易于临床推广应用。 Objective To investigate the clinical application value of 13C-UBT.Methods Rapid urease test and HE test performed in 180 patients. Hp status was evaluated by three tests: rapid urease test ,HE, 13C-UBT.The combined detection of RUT and HE was regarded as “gold standard” to evaluate the 13C-UBT .Result 98 patients were diagnosed as Hp positive and 82 as negative by“gold standard”. 13C-UBT was positive in 94 of 98 patients, and negative in 79 of 82 patients. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of 13C-UBT were 95.9%,96.3%,96.1%,96.9%,95.2%. Conclusion The test suggest that 13C-UBT is a simple,rapid,non-invasive method and has high sensitivity and specificity for the detection of Hp infection
