摘要
目的研究寡克隆区带(OCB)和IgG指数在多发性硬化(MS)中的临床意义。方法收集MS患者54例和其他神经系统疾病(OND)患者271例,包括中枢神经系统感染性疾病62例及非感染性疾病209例的脑脊液和血清标本,分别进行OCB检测(聚丙烯酰胺凝胶电泳)和IgG指数的计算(免疫火箭电泳法)。结果MS组OCB阳性率为35.2%;OND组为8.9%,其中感染组为24.2%,非感染组为4.5%。MS与OND组整体比较OCB阳性率有显著性差异(P<0.05),但与感染组相比无显著性差异(P>0.05)。MS组IgG指数阳性率为83.3%,OND组为78.2%(P>0.05)。结论OCB对MS有一定的辅助诊断价值,但需除外CNS感染性疾病。IgG指数阳性可作为参考。
Objective To study the positive rates of oligoclonal bands（OCB）and the IgG index in patients with multiple sclerosis（MS）and in other nervous system disorders（OND）.Methods Cerebrospinal fluid（CSF）and serum were collected from 54 patients with MS,271 patients with OND including 62 patients with infections of central nervous system and 209 patients with non-infections.The OCB and IgG index of CSF and serum were detected.Results The positive rate of OCB was 35.2% in MS,8.9% in OND（P〈0.05）,in which 24.2% in infections of central nervous system（P〉0.05）,4.5% in non-infections of central nervous system.The positive rate of IgG index was 83.3% in MS,78.2% in OND（P〉0.05）.Conclusion OCB is helpful to diagnose MS if infection diseases have be excluded,while IgG index can be referenced.
