Tumor necrosis factor and interleukin-1 in the CSF and sera of patients with multiple sclerosis 总被引:2,自引:0,他引:2

Serum and cerebrospinal fluid (CSF) from 31 patients with multiple sclerosis (MS) were examined to determine the levels of tumor necrosis factor (TNF) and interleukin (IL)-1 alpha (or IL-1 beta) by an enzyme-linked immunosorbent assay. TNF was detected in 29 (93.5%) of CSF from 31 cases of MS. TNF was also detectable in 100% of CSF from patients with acute relapsing MS in exacerbation. Patients with acute relapsing MS in exacerbation showed significantly higher CSF levels of TNF as compared with either those in remission or the controls (P less than 0.001 and P less than 0.0001, respectively). Increased levels of TNF were also detected in 35.5% of the MS sera, and especially in those with acute relapsing MS in exacerbation. Increased TNF levels were also frequent in the CSF and sera of patients with Guillain-Barré syndrome (GBS), which is also a demyelinating disease. No IL-1 alpha (or IL-1 beta) was detected in either CSF or sera of 31 MS patients. It is considered likely that TNF CSF levels may reflect disease activity in MS. 相似文献

Tumor necrosis factor-α (TNF-α) is a potent mediator produced by activated T lymphocytes and macrophages, which may play a role in the pathogenesis and development of multiple sclerosis (MS) and HTLV-1-associated myelopathy (HAM). The first step in the induction of many biological effects elicited by TNF-α is its binding to specific cell surface receptors. A soluble form of TNF receptors (sTNF-R) can be detected in the body fluid. We measured sTNF-R levels in the sera and cerebrospinal fluid (CSF) of patients with either MS or HAM, and evaluated the correlation between this mediator and diseaseaactivity. The levels of sTNF-R in the sera and CSF of patients with MS were significantly increased compared with controls, particularly patients with acute relapsing MS during an exacerbation (P < 0.001). CSF levels of sTNF-R showed a strong correlation with those of TNF (r = 0.716, P < 0.001). Higher levels of sTNF-R in the sera of HAM patients were detected as compared with those of either controls (P < 0.001) or non-HAM carriers (P < 0.001). Patients with HAM exhibited significantly higher CSF levels of sTNF-R than those with other neurological diseases (P < 0.0001). These results suggest that the detection of sTNF-R in the sera and CSF may predict disease progression. Availability of such a marker wou ld be useful in monitoring disease activity. 相似文献

Activation of complement is critically involved in inflammatory reactions in both Guillain-Barré syndrome (GBS) and multiple sclerosis (MS). Soluble human complement receptor 1 (sCR1) blocks complement activation by both classical and alternative pathways. We studied serum and cerebrospinal fluid (CSF) concentrations of sCR1 in 23 patients with GBS, 27 patients with MS and 30 controls. No significant differences were found between patients and controls. Transient liver affection probably caused high serum sCR1 levels in two patients with GBS. The serum and CSF sCR1 levels were not correlated to the disease activity of GBS and MS, nor to the relapsing-remitting or chronic-progressive forms of MS. In GBS the CSF sCR1 levels correlated with the CSF total protein concentrations (r = 0.9, P < 0.01), suggesting that sCR leaks from serum into CSF via a damaged blood-nerve barrier. The serum sCRl levels in GBS were slightly higher than in MS (P < 0.05). Whether this reflects changes in the release or consumption of sCR in these patients is at present unknown. 相似文献

Cytokine levels in the cerebrospinal fluid and serum of patients with multiple sclerosis 总被引:8,自引:2,他引:6
Interleukin (IL) 1 beta, tumor necrosis factor alpha (TNF alpha), and IL-6 are cytokines which mediate cellular responses during immune activation and inflammation. In multiple sclerosis (MS) they might be responsible for T-cell activation (IL-1 beta), for demyelination (TNF alpha), and for immunoglobulin (Ig) synthesis (IL-6) within the central nervous system. We studied IL-1 beta, TNF alpha, and IL-6 levels in the cerebrospinal fluid (CSF) of 34 patients with MS, 43 patients with non-inflammatory neurological diseases (NIND), and 19 patients with inflammatory neurological diseases (IND). IL-6 was found in the CSF of 29% of MS, 7% of NIND, and 47% of IND patients. TNF alpha was detected in the CSF of 23% of MS, 7% of NIND, and 29% of IND. CSF IL-6 and TNF alpha levels were significantly higher in MS and IND than in NIND. IL-1 beta was rarely detected in the CSF of any group. At least one cytokine was detected in 52% of MS CSF, 11% of NIND CSF, and 64% of IND CSF. In MS patients, no relationship was observed between the incidence or the amount of intrathecal IgG synthesis or oligoclonal bands and the presence of any cytokine. We also evaluated cytokine levels in paired sera from 11 MS and 13 NIND patients. Low levels of IL-6 were detected in most sera from MS and NIND patients. TNF alpha was detected in only two MS sera, and IL-1 beta was undetectable in any sample. Our results indicate that increased CSF levels of the cytokines IL-6 and TNF alpha occur frequently in MS and IND, but there is no obvious relationship to intrathecal Ig synthesis. 相似文献

We determined serum and cerebrospinal fluid (CSF) levels of the soluble 60-kDa tumour necrosis factor (TNF) receptor (sTNF-R
p60) in 50 patients with relapsing-remitting multiple sclerosis (MS) and in 18 patients with Guillain-Barré syndrome (GBS).
Neither in serum nor in CSF samples was there a statistically significant difference between mean receptor concentrations
of patients with MS (serum: 1064, SD 262 pg/ml; CSF: 555, SD 130 pg/ml), with other noninflammatory neurological diseases
(serum: 1008, SD 248 pg/ml; CSF: 530, SD 112 pg/ml) and with healthy control subjects (serum: 918, SD 180 pg/ml). In order
to determine disease activity, magnetic resonance imaging (MRI) of the brain was performed in all MS patients. The mean sTNF-R
p60 levels of patients who showed gadolinium DTPA enhancement on MRI were not different from those without enhancement (1034,
SD 274 pg/ml vs 1099, SD 248 pg/ml in serum samples and 546, SD 109 pg/ml vs 565, SD 152 pg/ml in CSF samples). In GBS, the
sTNF-R p60 levels of serum and CSF samples were significantly higher than in MS and all control groups except for the group
with viral meningitis (VM) (GBS: 1544, SD 834 pg/ml in serum, 882, SD 147 pg/ml in CSF; VM: 1518, SD 375 pg/ml in serum, 1131,
SD 611 pg/ml in CSF; P < 0.001 for serum samples and P < 0.005 for CSF samples). Serial serum sTNF-R p60 measurements in 13 patients with GBS showed an increase in receptor levels
parallel with the recovery from the disease (1276, SD 374 pg/ml at the time of disease onset, 1554, SD 482 pg/ml 14–24 days
later and 1787, SD 525 pg/ml after 28–32 days). From our results and the conflicting data of previous studies, we could not
agree with the suggestion that the assessment of sTNF-R p60 in MS patients is a useful marker for disease activity. In GBS,
subsequently increasing sTNF-R p60 levels are associated with recovery from the disease. It remains to be shown whether they
might represent a relevant pathogenetic factor during this stage of GBS.

We evaluated the relationship between the soluble form of vascular cell adhesion molecule-1 (sVCAM-1) and disease activity in patients with multiple sclerosis (MS) or with human T lymphotropic virus type 1-associated myelopathy (HAM), and measured levels of sVCAM-1 in their cerebrospinal fluid (CSF) and sera. Serum and CSF levels of sVCAM-1 were significantly increased in patients with acute relapsing MS during an exacerbation (P < 0.01 and P < 0.001), as well as in chronic progressive MS (P < 0.05 and P < 0.001), compared with healthy individuals and patients with other neurological diseases, respectively. Patients with acute relapsing MS during an exacerbation also exhibited significantly higher serum and CSF levels of sVCAM-1 vs. patients with acute relapsing MS in remission (P < 0.001). Significantly higher serum levels of sVCAM-1 were observed in patients with HAM vs. either healthy individuals (P < 0.01) or non-HAM carriers (P < 0.01). These results suggest that the determination of sVCAM-1 in the sera and CSF may be useful in monitoring the activity of MS and HAM. 相似文献

In the pathogenesis of Guillain-Barré syndrome (GBS) a dysregulation of cytokines is supposed. The protein concentration and mRNA expression of TNFalpha and TGFbeta1 were investigated in cerebrospinal fluid (CSF) and blood in 10 patients with GBS. TNFalpha-mRNA was increased at the beginning of the disease and demonstrated a decline during the time course (P = 0.001). The level of TNFalpha protein was elevated in only a few patients. TGFbeta1-mRNA (P = 0.001) and the active TGFbeta1 protein (P < 0.05) increased during the course of GBS, and the level of total TGFbeta1 protein was temporarily elevated (P = 0.005). A low ratio of TNFalpha-/TGFbeta-mRNA expression correlated to a good clinical course (P < 0.05). The results indicate an association of TNFalpha with disease activity. TGFbeta1 seems to terminate and limit the inflammatory reactions and to promote the healing course of GBS. In addition the investigations show that in GBS immunoregulatory mechanisms also take place in the CSF compartment itself and that CSF cells are involved in the production of pro-inflammatory as well as immunosuppressive cytokines. 相似文献
