目的:评价唾液抗幽门螺杆菌（Ｈｐ）抗体诊断Ｈｐ感染的价值。方法９３例病人同时进行唾液抗ＨｐＩｇＧ测定、快速尿素酶试验（ＲＵＴ）、组织涂片ＨＥ染色及病理ＷＳ银染色法诊断Ｈｐ感染。结果唾液抗ＨＰＩｇＧ检测阳性率近似于ＲＵＴ法（Ｐ＞０．０５），高于组织涂片ＨＥ染色法和病理ＷＳ银染色法（Ｐ＜０．０１）。其诊断Ｈｐ感染的敏感性为９６．９７％，特异性８８．２３％，准确性９５．１８％，阳性预测值９６．９７％，阴性预测值８８．２４％。结论唾液抗ＨＰＩｇＧ检测是诊断Ｈｐ感染的敏感性指标。
Objective: To evaluate the value of salivary anti-Helicobacter pylori (Hp) antibody in the diagnosis of Hp infection. Methods Ninety-three patients were tested for anti-HpIgG, rapid urease test (RUT), tissue smear HE staining and pathological WS silver staining for Hp infection. Results The positive rate of saliva anti-HPIgG was similar to that of RUT (P> 0.05), higher than that of histological stain HE staining and pathological WS silver staining (P <0.01). The diagnosis of Hp infection was 96.97%, specificity 88.23%, accuracy 95.18%, positive predictive value 96.97%, negative predictive value 88.24%. Conclusion Salivary anti-HPIgG test is a sensitive indicator of Hp infection.
