两种强直性脊柱炎临床诊断标准的比较

The comparison of two clinic criteria for diagnosing ankylosing spondylitis

目的:探讨并完善强直性脊柱炎的临床诊断标准,以提高确诊率及早期诊断率。方法:选取2005年10月-2009年6月间不明原因的腰骶部疼痛患者410例,分别用两种诊断标准对其进行诊断,统计分析修订后的诊断标准的灵敏度和特异度。结果:410例患者中,应用修订的纽约标准确诊为强直性脊柱炎者330例;修订后的诊断标准的灵敏度和特异度分别为94.29%和83.33%。4字试验和骶髂关节叩击痛在早期患者中更典型。结论:修订后的诊断标准简便易操作,有较好的灵敏度和特异度,更适合发现早期强直性脊柱炎患者。

Objective：To explore and perfect the criterion for diagnosing ankylosina spondylitis （AS） to improve the rates of comfirming diagnosis and early diagnosis.Method：Four hundred and ten patients with unexplained lumbosacral pain were selected and diagnosed during October 2005 to June 2009 using two criteria, and then analyzed the sensitivity and specificity of the two diagnosis criteria.Result：Of the 410 suspected patients 330 patients were identified as AS by revised New York criterion.And the sensitivity and specificity of revised New York criterion were 94.29% and 83.33% respectively.Faber-Patrick test and percussion pain on sacroiliac joint were significant in early period of AS.Conclusion：The revised criterion was easy to operate and proper for early diagnosis as its high sensitivity and specificity.
