通过检测末梢血抗幽门螺杆菌（Hp）IgG的方法，调查了南京市区102名消化科医护人员和130名非消化科医护人员的Hp感染状况。发现前者光密度值（0.71±0．29）非常显著地高于后者（0．49±0．28）（P＜0．005）；在消化科或内镜室工作＜5年、5～10年、＞10年的3组人群之间不存在显著性差异；消化科医生与护士比较（P＞0.05），内镜人员与普通消化科人员比较（P＞0.05），亦未显示显著性差异。初步认为：（1）消化科人员在医患接触中Hp感染的危险性高于医院内其他人群；（2）从事消化科临床工作5年之内获得Hp感染的危险度即已达到饱和值水平；（3）使用手套可能会降低医患接触过程中Hp感染的传播。
By detecting peripheral blood anti-Helicobacter pylori (Hp) IgG, we investigated the Hp infection status of 102 gastroenterologists and 130 non-gastroenterologists in Nanjing. The optical density (0.71 ± 0.29) of the former was significantly higher than that of the latter (0.49 ± 0.28) (P <0.005) (P> 0.05). There was no significant difference between the endoscopy staff and the general gastroenterology staff (P> 0.05), and there was no significant difference between the three groups of patients> 10 years and> 10 years. difference. It is preliminarily believed that: (1) the risk of Hp infection among patients in gastroenterology is higher than that of other people in the hospital; (2) the risk of getting Hp infection within 5 years of clinical work in Gastroenterology has reached the saturation level ; (3) the use of gloves may reduce the spread of Hp infection during the contact of the doctor and patient.
