Abstract

A 45-year-old Japanese man underwent esophagogastroduodenoscopy, which revealed spotty redness at the gastric fornix, mucosal swelling, diffuse redness in the corpus, and mucosal atrophy in the gastric angle and antrum. Histological examination showed rod-shaped bacteria that appeared larger than Helicobacter pylori. The patient tested positive for rapid urease test, and serum anti-H. pylori IgG antibody test results were negative. Further examination of the bacteria revealed that H. suis antibody test was positive, and the presence of H. suis was confirmed using H. suis-specific real-time PCR. H. suis was successfully eradicated after triple therapy with vonoprazan, amoxicillin, and clarithromycin. This case reinforces the notion that non-H. pylori Helicobacter species such as H. suis and H. heilmannii may be involved in the pathogenesis of active gastritis in patients who test negative for H. pylori antibodies.

瑞士幽门螺杆菌相关的胃炎模拟传统幽门螺杆菌相关的萎缩性胃炎。
一名45岁的日本男性患者行食管胃十二指肠镜检查,发现胃穹窿斑状发红,粘膜肿胀,胃体弥漫性发红,胃角和胃窦粘膜萎缩。组织学检查显示杆状细菌比幽门螺杆菌大。患者快速脲酶试验阳性,血清抗h抗体阳性。幽门螺杆菌IgG抗体检测结果均为阴性。进一步检测结果显示猪嗜血杆菌抗体检测呈阳性,采用猪嗜血杆菌特异性实时聚合酶链反应证实了猪嗜血杆菌的存在。猪嗜血杆菌经vonoprazan,阿莫西林和克拉霉素三联治疗后被成功根除。这个例子强化了非h。幽门螺杆菌种类,如猪螺杆菌和海氏螺杆菌,可能参与了幽门螺杆菌抗体检测阴性患者活动性胃炎的发病机制。
