【摘要】 目的 评价免疫印迹法幽门螺杆菌( H畅pylori) 抗体分型检测试剂盒检测 H畅pylori 菌株 分型的特性及 H畅pylori 分型与临床疾病的关系。 方法 对 2012 年 3 至 8 月因上消化道症状就诊于 全国 6 个中心接受过胃镜及病理检查,且进行13 C-尿素呼气试验的 378 例患者,采用 H畅pylori 抗体分 型检测试剂盒(免疫印迹法) 进行血清 H畅pylori 抗体检测,并进行分型。 以13 C-尿素呼气试验为金标 准,评价免疫印迹法诊断 H畅pylori 感染的敏感性、特异性及准确性,并与胶体金法血清抗体检测进行 比较。 分析 H畅pylori 分型与临床疾病的关系。 结果 378 例患者中13 C-尿素呼气试验确诊 H畅pylori 阳 性患者 257 例,H畅pylori 阴性患者 121 例。 以13 C-尿素呼气试验作为诊断的金标准,免疫印迹法检测诊 断 H畅pylori 感染的敏感度为 97畅7%,特异度为 86畅8%,阳性预测值为 94畅0%,阴性预测值为 94畅6%, 一致率为 94畅2%;胶体金法检测 H畅pylori 感染的敏感度为 84畅4%,特异度为 92畅6%,阳性预测值为 96畅0%,阴性预测值为 73畅7%,一致率为 87畅0%。 251 例13 C-尿素呼气试验和免疫印迹法均阳性的患 者中,H畅pylori 根除反复失败患者与 H畅pylori 未根除治疗患者,经免疫印迹法检测,Ⅰ型 H畅pylori 阳性 率差异无统计学意义[93畅0%(53 /57) 比 93畅8%(182 /194),P =0畅764];H畅pylori 未根除治疗患者中, 非萎缩性胃炎、萎缩性胃炎和十二指肠溃疡Ⅰ 型 H畅pylori 阳性 率 分别 为 94畅2% (65 /69)、89畅9% (62 /69)和 98畅2%(55 /56),十二指肠溃疡患者Ⅰ型 H畅pylori 阳性率高于胃炎患者,但差异未达统计 学意义( P =0畅185)。 结论 以13 C-尿素呼气试验为金标准,免疫印迹法 H畅pylori 抗体分型检测与胶 体金法两种血清 H畅pylori 抗体检测诊断 H畅pylori 感染的准确性均比较高。 不同类型 H畅pylori 致病力 有差异,Ⅰ型 H畅pylori 比Ⅱ型有更强的致病力,更易致消化性溃疡。 H畅pylori 根除反复失败患者与 H畅pylori 未根除治疗患者Ⅰ型 H畅pylori 阳性率无明显差异,有待进一步研究。
