现行指南建议:在进行幽门螺杆菌尿素呼气试验前,应停止使用质子泵抑制剂(PPIs)。据近期出版的《美国胃肠病学杂志》报道,新指南增加了饮用柠檬酸的试验,鉴于柠檬酸可减少假阳性率,因此无需停止抑制胃酸的治疗。
Current guidelines suggest that proton pump inhibitors (PPIs) should be discontinued prior to the H. pylori urea breath test. According to a recent issue of the American Journal of Gastroenterology, the new guidelines add trials of drinking citric acid, and since citric acid reduces false-positive rates, there is no need to stop the inhibition of gastric acid.
