摘要
目的研究多发性硬化(MS)免疫异常过程中肿瘤坏死因子(TNF-α)和循环细胞间粘附分子-1(cICAM-1)的变化及与血脑屏障(BBB)的相关性。方法用酶联免疫吸附试验(ELISA)及单项琼脂扩散(SIRD)检测临床确诊为MS的31例病人血清及脑脊液(CSF)中TNF-α、cICAM-1及白蛋白(Alb)比值。结果①31例MS患者中Alb比值轻度异常8例(25%),正常者23例;IgG指数增高(>0.7)者21例(68%)。②MS组CSF及血清中可检出高水平TNF-α,较对照组显著增高(P<0.01,P<0.05);CSF中cICAM-1水平较对照组增高明显,差异有显著性(P<0.01)。③活动性MS患者CSF中TNF-α水平较静止期增高,差异有显著性(P<0.01)。两组cICAM-1水平也有显著差异(P<0.05)。④BBB轻微损害 MS的 CSF中 cICAM-1水平较 BBB正常组增高,且与 CSF中 TNF-α水平呈正相关(r=0.478)。结论CSF及血清中高水平TNF-α与cICAM-1可能在MS病人鞘内炎症病理机制中起重要作用,cICAM-1可能成为MS活动的标志。一部分MS有一定程度BBB损害且?
Objective To examine the changes of tumor necrosis factor-α(TNF-α) and circulating intercellular adhesion molecule-1 (cICAM-1 ) in patients with multiple sclerosis(MS) and the correlation with blood-brain barrier(BBB) .Methods Levels of cICAM-1 and TNF-α from 31 patients with clinically definite MS were detected by ELISA, and BBB function was evaluated by CSF/serum ratio and the paired CSF and serum samples. Results ①There were 8 mild abnormal(25. 8%) and 23 normal of Alb ratio in 31 MS patients. Twenty one patients (68% ) out of 31 were abnormal of IgG-Index(> 0. 7). ②In 31 MS patients, higher TNF-αlevels were determinated in serum and CSF, compared to control group(P < 0.05 and P < 0.01 respectively) .The level of cICAM-1 in CSF of MS patients was also elevated(P < 0.01). ③TNF-α level of CSF in active MS patients was higher than that in patients with stable MS.④The level of cICAM-1 in CSF of MS patients with mildly damaged BBB was higher than that in patients with normal BBB and associated with the level of TNF-α in CSF which showed a moderate correlation(r = 0.478). Conclusion The high levels of cICAM-1 and TNF-α may play an important role in intrathecal inflammatory pathogenesis in MS and cICAM-1 might be marker of activity in MS.
