摘要
目的比较诊断多发性硬化（multiple sclerosis，MS）的Poser标准和McDonald新标准。方法将Poser标准和McDonald新标准回顾性应用于临床表现提示为MS的67例患者，采用Fisher精确检验对两种诊断标准进行比较分析。结果符合Poser临床和实验室确诊者分别为34例和24例，可能MS者9例，符合McDonald标准的MS确诊者36例，可能MS者31例，两种标准的诊断阳性率差异有统计学意义（OR=5．549，95％CI 2．37～13．00，P〈0．01）。结论两种标准在诊断MS，尼其在确诊MS时有明显差异，这可能主要与Poser标准更多地依赖各种亚临床证据，而McDonald标准采用了更为严格的MRI规定有关，脑脊液分析可能在一定程度上有助于提高MS的确诊率和MRI异常的病理特异性。
Objective To compare the Poser and the McDonald diagnostic criteria for multiple sclerosis （MS）. Methods Sixty-seven patients with clinical features suggestive of MS were re-evaluated by 2 neurologists utilizing both the Poser and the McDonald criteria. The Fisher＇s exact test was used to statistically analyze the data from assessment by these two criteria. Results By the Poser criteria, 34 patients were classified as clinically definite MS, 24 patients as laboratory supported definite MS and 9 patients as possible MS. Under the new McDonald criteria, MS was diagnosed in 36 patients and 31 patients had possible MS. The results revealed significant differences in diagnosing MS between these 2 criteria （ OR = 5. 549, 95% CI 2. 37-13.00, P 〈 0. 01 ）. Conclusions These 2 criteria showed remarkable differences in diagnosing MS, in particular definite MS, possibly due to greater reliance on paraclinical evidences in the Poser criteria and more stringent guidlines of magnetic resonance imaging （MRI） in the McDonald criteria. The analysis of cerebrospinal fluid may increase the diagnostic rate of MS and specify pathologic abnormalities in MRI to some degree.
