复发性口腔溃疡患者口腔幽门螺杆菌的检测

目的 探讨复发性口腔溃疡(RAU)的发病与口腔幽门螺杆菌(Hp)感染及消化道疾病之间的关联.方法 以RAU患者唾液为模板,设计引物,用PCR,检测82例RAU患者口腔中Hp阳性率情况.结果 82例RAU患者和74例健康人群,Hp阳性率分别为43.9%和16.2%(P＜0.001);82例RAU患者中,伴有胃肠道疾病的22例,占26.82%;74例健康人群中,伴有胃肠道疾病的7例,占10.45%.比较RAU与非RAU患者中,胃肠道疾病的发病率有显著差异(P＜0.01).结论 Hp感染与RAU的发病之间有某种潜在的关联.RAU患者较健康人群胃肠道疾病患病率高.

Detection of Helicobacter pylori in oral cavity of patients with recurrent aphthous ulcer

Objective To investigate the association of recurrent aphthous ulcer (RAU) with Helicobacter pylori (Hp) infection and digestive diseases. Methods Saliva samples were collected from 82 patients with RAU and 74 healthy volunteers for Hp detection with PCR. Results The positivity rates of HP differed significantly between RAU patients and healthy volunteers (43.9% vs 16.2%, P<0.001). In the 82 RAU patients, 22 (26.82%) were identified to have gastritis and peptic ulcer, whereas only 7 out of the 74 healthy volunteers (10.45%) had such digestive diseases, showing significant difference between them (P<0.01). Conclusion Hp might in some way associate with RAU, which in turn is associated with an increased incidence of digestive diseases.
