目的:调查海军某部官兵幽门螺杆菌(H.pylori)感染情况,比较3种H.pylori检测方法的敏感度和特异性。方法:分别采用13C呼气试验(13C-UBT)、血清H.pylori抗体(Hp-IgG)检测、粪抗原快速免疫卡检测(HpSAT)对海军某部官兵864例进行H.pylori检测,以上述3项检测中有2或3项均阳性判定存在H.pylori感染,比较3种方法对H.pylori感染的检出率、敏感度及特异性。结果:864例中,H.pylori感染343例,检出率39.7%;13 C-UBT与血清Hp-IgG检测阳性率显著高于HpSAT检测(P<0.05)。13C-UBT和血清Hp-IgG检测H.pylori感染的敏感度非常显著高于HpSAT检测(P<0.01),血清Hp-IgG检测和HpSAT检测H.pylori感染的特异性显著高于13C-UBT(P<0.05)。结论:血清Hp-IgG检测敏感度和特异性均较高,筛查海军官兵H.pylori感染情况,建议先行Hp-IgG检测,对检测结果阳性者再行13C-UBT。
Objective: To investigate the infection of Helicobacter pylori (H.pylori) in a certain unit of the Navy and to compare the sensitivity and specificity of three H.pylori detection methods. Methods: HpSAT was used to detect H.pylori in 864 cases of officers and soldiers of a certain naval unit by using 13C-UBT, Hp-IgG and HpSAT respectively. Two or three of the three tests were positive for the presence of H.pylori infection, and the detection rate, sensitivity and specificity of the three methods for H.pylori infection were compared. Results: The positive rate of 13 C-UBT and serum Hp-IgG was significantly higher than that of HpSAT (P <0.05) in 864 cases, of which 343 cases were infected with H.pylori, the detection rate was 39.7%. The sensitivity of H.pylori infection to 13C-UBT and serum Hp-IgG was significantly higher than that of HpSAT (P <0.01). The specificity of H.pylori infection by serum Hp-IgG and HpSAT was significantly higher than that of 13C-UBT P <0.05). Conclusion: The sensitivity and specificity of serum Hp-IgG test are high. Screening for H.pylori infection in naval officers and men suggests that Hp-IgG test should be performed first, and 13C-UBT should be tested again if the test result is positive.
