No biological parameter is currently available as a specific marker of multiple sclerosis (MS) activity. The aim of this study was to determine whether an evolution of the neurological disability is associated with a modified profile of cytokine production. Clinical disease activity was quantitated by the Kurtzke's expanded disability status scale (EDSS). Whole blood was stimulated with phytohemagglutinin (PHA) for 2 hours at 37 degrees C and the activated plasma was assayed for Tumor necrosis factor alpha (TNF-alpha) and Interleukin-1 beta (IL-1 beta). Relapsing-remitting MS patients enduring a relapse (RRMS, in relapse) (721 +/- 58 pg/ml, n = 27) and chronic progressive MS (CPMS) patients (516 +/- 33 pg/ml, n = 17) had an higher TNF-alpha production capacity as compared to healthy subjects (143 +/- 25 pg/ml, n = 17), RRMS, stable patients, (123 +/- 11 pg/ml, n = 26) or other neurological diseases (OND) without immunological or inflammatory disease in the peripheral immune compartment (131 +/- 24 pg/ml, n = 14) (t test: p < 0.0001). IL-1 beta production was also significantly higher but to a lesser extent in the same conditions. Concentration of TNF-alpha was also found to be significantly higher in the cerebrospinal fluid (CSF) of CPMS patients (199 +/- 7.8 pg/ml, n = 7, p < 0.0001) but also in RRMS, in relapse (149 +/- 5.7 pg/ml, n = 11, p < 0.05) as compared to RRMS, stable (130 +/- 4.4 pg/ml, n = 7) or OND without inflammatory or immunological disease of the central nervous system (CNS) (142 +/- 6.2 pg/ml, n = 8).(ABSTRACT TRUNCATED AT 250 WORDS)

Depression is a common problem in multiple sclerosis (MS) and affects about 50% of MS patients. Since a dysregulation of cytokine levels has been implicated in the pathogenesis of MS and alterations in cytokine serum levels have been found in depressive illness, we examined the relationship between depressive symptoms, cytokine mRNA expression levels of Th1-type and Th2-type cytokines and neurological disability among early diagnosed MS patients in a prospective study. Sixteen patients with clinically or laboratory supported MS were assessed using the Beck Depression Inventory (BDI) and the Kurtzke Expanded Disability Status Scale (EDSS). Cytokine mRNA in whole blood was serially determined by a new quantitative polymerase chain reaction (PCR) method. BDI sum scores (2,9 fold) and the expression levels of tumor necrosis factor-alpha (TNF-alpha; 4 fold), interferon-gamma (IFN-gamma; 4,6 fold) and interleukin-10 (IL-10; 6,1 fold) mRNA were increased in MS patients during an acute attack compared to age and sex matched healthy controls. We detected a significant positive correlation between TNF-alpha (r=0.55) and interferon-gamma (r=0.54) mRNA expression and the BDI sum scores during an acute attack in MS patients. At follow-up after 3-6 months, only TNF-alpha mRNA expression was correlated with BDI sum scores (r=0.62 resp. r=0.31). No correlation of the BDI sum scores with Th2-type cytokine mRNA expression for interleukin-4 (IL-4) and interleukin-10 (IL-10) or with the extent of neurological disability was observed. The possible contribution of Th1-type cytokines to the development of depression in MS is discussed.

A large body of data indicates that multiple sclerosis (MS) is an autoimmune disease which is initiated by CD4(+) T-helper 1 (Th1) and Th17 cells that are reactive against proteins in the myelin sheath. MS typically begins with a relapsing-remitting course, punctuated by clinical exacerbations associated with the development of focal inflammatory lesions in central nervous system white matter, followed by a secondary progressive (SP) phase, characterized by a gradual accumulation of neurological disability associated with widespread microglial activation and axonal loss. The molecular and cellular basis for this transition is unclear, and the role of inflammation during the SP stage is a subject of active debate. As of now, no immunological biomarkers have been identified in MS that are predictive of the clinical course or therapeutic responsiveness to disease-modifying agents, or that correlate with new lesion development, cumulative lesion load, or degree of disability. The discovery of such biomarkers would greatly facilitate clinical management and provide power for smaller and shorter clinical trials. In this article, we discuss the literature on immunological biomarkers in MS with a focus on stage-specific differences and similarities.
