Axonal damage markers in the cerebrospinal fluid of patients with clinically isolated syndrome improve predicting conversion to definite multiple sclerosis

Clinically isolated syndrome (CIS) represents the earliest phase of multiple sclerosis (MS). This study tested whether biomarkers for axonal degeneration can improve upon sensitivity and specificity of magnetic resonance imaging (MRI) parameters in predicting conversion from CIS to MS. Patients with CIS (n = 52), relapsing-remitting MS (RRMS, n = 38) and age-matched controls (n = 25) were included. Cerebrospinal fluid (CSF) levels of tau and neurofilaments (NfHSMI35) were measured using ELISA. The MRI T2-lesion load and the Expanded Disability Status Scale (EDSS) were recorded. CSF tau and NfHSMI35 were elevated in CIS compared to controls (P<0.05). RRMS patients with acute relapse had higher NfHSMI35 levels than stable patients. Tau and NfHSMI35 levels correlated with EDSS in CIS and RRMS. In RRMS, the number of T2-lesions correlated with tau levels (R = 0.53, P = 0.01). The sensitivity predicting the conversion from CIS to MS was higher for the combination of CSF markers (either tau or NfHSMI35 elevated) than for MRI (40 versus 34%), but could be further increased to 60% if CSF and MRI criteria were combined. Similarly, the combination of tau and NfHSMI35 showed higher specificity (94%) than MRI (82%). Tau and NfHSMI35 are valuable biomarkers for axonal damage in the CIS patients. Predicting conversion from CIS to MS can be improved if CSF markers are combined with MRI.

Abstract：

Objective To investigate the evolution of CXCL10 in blood plasma and cerebrospinal fluid (CSF) during relapses of multiple sclerosis (MS),and the correlation between these and the clinical neurological dysfunction.Methods Fifty-three patients with definite MS during relapsing state (relapsing MS group) diagnosed by the McDonald criteria;fifty-three patients with definite MS during remitting state ( remitting MS group);thirty-two patients with non-inflammatory neurologic disease ( NIND group) and fiftythree healthy controls (NC group) were enrolled in the study.Each patient clinical status was evaluated with the Expanded Disability Status Scale ( EDSS).Plasma and CSF levels were analyzed by enzyme-linked immunoassay.Results ( 1 ) The CXCL10 level in plasma in relapsing MS group elevated significantly between the 2nd ( (601 ± 365 ) pg/ml,t = - 2.898,P = 0.001) and the 4th ( (575 ± 297 ) pg/ml,t = -2.651,P=0.003) week after relapsing;GXL10 in CSF (n =32) did not changed significantly in the 4th week after relapsing( (1807 ±803) pg/ml).(2) The CXCL10 level in plasma in relapsing MS group were significantly higher than that in the healthy control group ((248±130) pg/ml,(=4.895,P=0.000) and remitting MS group ((287 ±118) pg/ml,t = 3.555,P = 0.001 ).( 3 ) The CXCL10 level in CSF in relapsing MS group (( 1774 ± 604) pg/ml) was significantly higher than that in NIND group ( ( 122 ± 114) pg/ml,t= 15.192,P =0.000).(4) The CXCL10 level in plasma in relapsing MS group had correlation with that in CSF (r=0.792,P=0.001).The CXCL10 level in CSF in relapsing MS group had correlation with EDSS scores (r = 0.526,P = 0.002 ).Conclusions The CXCL10 level in plasma might be implemented as a paraclinical marker of disease activity in MS.The CXCL10 level in plasma of MS may be relevant to that in CSF.The CXCL10 level in CSF of MS may indicate the clinical neurological dysfunction.     

Clinical, MRI, CSF and electrophysiological findings in different stages of multiple sclerosis

Effective therapy in the earliest stages of multiple sclerosis (MS) demands early correct diagnosis. Retrospective analysis included 130 patients (90 women) with a median age of 35.5 years, median duration of the disease of 2 years and median EDSS score of 3.0. Twenty-seven patients had clinically isolated syndrome (CIS) suggestive of MS, 66 relapsing-remitting (RR) MS, 19 secondary progressive (SP) MS and 18 primary progressive (PP) MS. The predominant symptoms were sensory in 52% of the patients with CIS compared to 27% in patients with RRMS, whereas they were more often motor in patients with PPMS. Patients with CIS had higher CSF cell counts than patients diagnosed in later stages of the disease and oligoclonal bands were found in 89% of all patients without statistically significant differences between the subgroups. Prolonged latencies of visual evoked potentials (VEP) were found in only 29% of patients with CIS compared to 66% in RRMS, 75% in SPMS and 65% of PPMS patients. Fifty-six percent of patients with CIS, 88% with RRMS, 74% with SPMS and 78% of patients with PPMS fulfilled modified the Barkhof et al. MRI criteria at the time of diagnosis. Patients in early MS often present with sensory symptoms. Brain MRI can be inconclusive in over 40% of patients with CIS but the elevated CSF cell count and positive oligoclonal bands are helpful in establishing the diagnosis of CIS suggestive of MS. In later stages of the disease the combination of clinical features, MRI, prolonged VEP latencies and positive CSF oligoclonal bands secures the correct diagnosis.     

Characterization of the T cell receptor repertoire in the Japanese neuromyelitis optica: T cell activity is up-regulated compared to multiple sclerosis

To characterize T cell immunity in Japanese neuromyelitis optica (NMO), we examined the T cell receptor (TCR) repertoire in NMO patients with complementarity-determining region 3 (CDR3) spectratyping and compared the results with those from multiple sclerosis (MS) patients and healthy subjects. Both NMO and MS patients had a larger number of clonally expanded Vbeta genes than healthy subjects. Moreover, NMO patients had a significantly larger number of expanded Vbetas than MS patients. The detailed analysis revealed that Vbeta1 and Vbeta13 were significantly activated in NMO than MS. These results reflected unique pathophysiology of Japanese NMO, which is distinguishable from that of MS. Furthermore, longitudinal examinations of the TCR repertoire demonstrated that the number of clonally expanded Vbetas in NMO correlates with the Kurtzke Expanded disability status scale (EDSS). Although the activation pattern of the TCR repertoire in relapsing-remitting MS (RRMS) was similar to that in NMO, secondary progressive MS (SPMS) patients with longer disease durations and higher EDSS scores consistently had a smaller number of clonally expanded Vbetas than RRMS patients. Detailed TCR investigations will provide useful information to evaluate the clinical and immunological status of NMO and MS and to develop effective immunotherapies.     

C/EBP homologous protein investigation in the serum and cerebro-spinal fluid of relapsing-remitting multiple sclerosis patients

The exact determination of endoplasmic reticulum (ER) stress-associated proteins is not completely elucidated in the multiple sclerosis (MS) patients. We measured CHOP concentrations in the serum and cerebro-spinal fluid (CSF) of relapsing-remitting MS (RRMS) patients (n = 20) in comparison with the non-MS control group (n = 20) to determine whether this marker could be detected in the body fluids of RRMS patients. CHOP marker was not detectable in all harvested CSF samples. However, its levels were detectable in all serums harvested from both non-MS and RRMS patients and its levels in the latter group were not significantly higher than those of the non-MS control group (P value = 0.265). CHOP was not detectable in the CSF of RRMS patients in spite of the recent reports on the RRMS autopsies. Additionally, there were not any significant correlations (Spearman's correlation) between both of EDSS score and age with CHOP serum concentrations in all subjects.
