A gastric juice-based PCR assay was compared with culture, microscopy, and a rapid urease test with specimens from 114 subjects. The PCR and conventional tests were positive for 76 and 62% of the subjects, respectively. The prevalence of gastroduodenal disease and seropositivity for anti-Helicobacter pylori immunoglobulin G were similarly high among conventional-test-positive and PCR-only-positive subjects compared to all-negative ones. The PCR assay is recommended to confirm the H. pylori status of culture-negative peptic-ulcer patients.
将基于胃液的聚合酶链反应(PCR)检测方法与培养法、显微镜检查法以及对114名受试者的标本进行的快速尿素酶试验进行了比较。PCR检测和传统检测的受试者阳性率分别为76%和62%。与所有检测均为阴性的受试者相比,在传统检测阳性和仅PCR检测阳性的受试者中,胃十二指肠疾病的患病率和抗幽门螺杆菌免疫球蛋白G血清阳性率同样较高。建议采用PCR检测来确认培养阴性的消化性溃疡患者的幽门螺杆菌感染状况。
