Clarithromycin resistance is a crucial factor in the eradication of Helicobacter pylori. This study aimed to evaluate the performance of MmaxSure™ H. pylori & ClaR Assay (MmaxSure™) in the diagnosis and detection of clarithromycin resistance in H. pylori.
Subjects who underwent esophagogastroduodenoscopy between April 2020 and October 2022 were enrolled. The diagnostic performances of MmaxSure™ and dual priming oligonucleotide (DPO)-based multiplex polymerase chain reaction (PCR) were compared with the rapid urease test and culture. Secondary gene sequencing analysis was performed in discordant cases of PCR tests.
A total of 156 gastric biopsy samples were analyzed. In H. pylori detection, MmaxSure™ showed a 95.9% sensitivity (95% CI: 90.6-98.6), a 42.7% specificity (95% CI: 26.3-60.7), and a kappa value of 0.457. For the detection of A2143G mutation samples, MmaxSure™ showed a 91.2% sensitivity (95% CI: 76.3-98.1), a 93.4% specificity (95% CI: 87.5-97.1), and a kappa value of 0.804. There were a total of 10 discordant cases compared to gene sequencing in A2143G mutation detection for MmaxSure™.
In this study, MmaxSure™ showed comparable diagnostic performance to DPO-PCR in the detection of the H. pylori and A2143G mutation. Further research is needed to confirm the clinical effectiveness of the MmaxSure™ assay in H. pylori eradication.
克拉霉素耐药性是根除幽门螺杆菌的关键因素。本研究旨在评估 MmaxSure™ H. pylori & ClaR 检测试剂盒(MmaxSure™)在诊断和检测幽门螺杆菌克拉霉素耐药性方面的性能。
纳入 2020 年 4 月至 2022 年 10 月间接受胃镜检查的受试者。比较了 MmaxSure™与双引物寡核苷酸(DPO)-多重聚合酶链反应(PCR)对快速尿素酶试验和培养的诊断性能。对 PCR 检测结果不一致的病例进行二次基因测序分析。
共分析了 156 个胃活检样本。在幽门螺杆菌检测中,MmaxSure™ 的灵敏度为 95.9%(95%CI:90.6-98.6),特异性为 42.7%(95%CI:26.3-60.7),kappa 值为 0.457。对于 A2143G 突变样本的检测,MmaxSure™ 的灵敏度为 91.2%(95%CI:76.3-98.1),特异性为 93.4%(95%CI:87.5-97.1),kappa 值为 0.804。与基因测序相比,MmaxSure™ 在 A2143G 突变检测中有 10 个不一致的病例。
在本研究中,MmaxSure™ 在检测幽门螺杆菌和 A2143G 突变方面的诊断性能与 DPO-PCR 相当。需要进一步研究来证实 MmaxSure™ 检测试剂盒在幽门螺杆菌根除方面的临床效果。
