The prevalence of Helicobacter pylori infection in a population-based sample of 477 children (mean age plus minus standard deviation, 5.8 plus minus 0.5 years) determined by the [(13)C]urea breath test ([(13)C]UBT) was 10.7% (95% confidence interval [CI], 8.1 to 13.8%), and that determined by salivary enzyme-linked immunosorbent assay (ELISA) was 11.9% (95% CI, 9.2 to 15.2%). Compared to the [(13)C]UBT, the sensitivity and specificity of the salivary ELISA were 80.9% (95% CI, 66.3 to 90.4%) and 95.3% (95% CI, 92.7 to 97.1%), respectively.
通过[¹³C]尿素呼气试验([¹³C]UBT)对477名儿童(平均年龄±标准差,5.8±0.5岁)的群体样本进行检测,幽门螺杆菌感染率为10.7%(95%置信区间[CI],8.1%至13.8%);通过唾液酶联免疫吸附测定(ELISA)得出的感染率为11.9%(95%CI,9.2%至15.2%)。与[¹³C]UBT相比,唾液ELISA的灵敏度和特异性分别为80.9%(95%CI,66.3%至90.4%)和95.3%(95%CI,92.7%至97.1%)。
