目的:
明确国际脊柱关节病专家协作组(ASAS)脊柱关节病(SPA)分类标准的预测效度。
方法:
29个中心(例)的22个中心(例)患者参加了该ASAS队列研究。患者有慢性(>3?月)病因不明的背痛并且发病年龄45岁以下(n=)或外周关节炎和/或附着点炎和/或指炎(n=)。在随访中的信息是在诊所访问或通过电话获取的。采用风湿病的诊断标准估ASAS分类标准的基线值的阳性预测值(PPV)。
结果:
共有例患者参与了评估(次就诊;次电话),平均随访4.4?年(范围:1.9-6.8年),70.2%例经风湿免疫科专家诊断为脊柱关节病。例患者在基线水平符合中轴脊柱关节病或外周脊柱关节病的诊断标准,其中例在随访中诊断为脊柱关节病(阳性预测值:92.2%)。中轴脊柱关节病和外周脊柱关节病标准的阳性预测值分别为93.3%和89.5%。仅有临床支的阳性预测值为88%,而临床支±影像支为96%,仅有成像支的阳性预测值为86.2%,而影像支±临床支为94.7%。一系列的敏感性分析也得到了类似的结果(范围:85.1-98.2%)。
结论:
该中轴脊柱关节病和外周脊柱关节病的阳性预测值标准可有效预测4年后专家诊断脊柱关节病。中轴脊柱关节病诊断标准的影像支和临床支的标准具有相似的预测效度,具有互补性。
