BACKGROUND: The MSBase prediction model of treatment response leverages multiple demographic and clinical characteristics to estimate hazards of relapses, confirmed disability accumulation (CDA), and confirmed disability improvement (CDI). The model did not include Multiple Sclerosis Severity Score (MSSS), a disease duration-adjusted ranked score of disability. OBJECTIVE: To incorporate MSSS into the MSBase prediction model and compare model accuracy with and without MSSS. METHODS: The associations between MSSS and relapse, CDA, and CDI were evaluated with marginal proportional hazards models adjusted for three principal components representative of patients' demographic and clinical characteristics. The model fit with and without MSSS was assessed with penalized r2 and Harrell C. RESULTS: A total of 5866 MS patients were started on disease-modifying therapy during prospective follow-up (age 38.4 ± 10.6 years; 72% female; disease duration 8.5 ± 7.7 years). Including MSSS into the model improved the accuracy of individual prediction of relapses by 31%, of CDA by 23%, and of CDI by 24% (Harrell C) and increased the amount of variance explained for relapses by 49%, for CDI by 11%, and for CDA by 10% as compared with the original model. CONCLUSION: Addition of a single, readily available metric, MSSS, to the comprehensive MSBase prediction model considerably improved the individual accuracy of prognostics in MS.

A total of 195 patients with multiple sclerosis (MS) and 126 controls were investigated for angiotensinogen/(-6)A/G, M235T/and angiotensin converting enzyme I/D gene polymorphisms to test their association with MS susceptibility and/or disease progression using Global Multiple Sclerosis Severity Score (MSSS). We demonstrated a significant association of M235T polymorphism with MSSS. The MM homozygotes had the lowest (3.8), heterozygotes MT higher (5.2) and homozygotes TT the highest (5.4) mean MSSS values (P=0.02). For polymorphisms (-6)A/G of ATG, only a trend was observed (P=0.06), where the homozygotes GG carried lower MSSS values than heterozygotes and homozygotes AA. No significant association with susceptibility was observed. For ACE I/D polymorphism, neither significant differences in the genotype-phenotype study nor in the case-control study were observed.

OBJECTIVE: In multiple sclerosis (MS), deep grey matter (DGM) atrophy has been recognised as a crucial component of the disease that presents early and it has been associated with disability. Although the precise mechanism underlying grey matter atrophy is unknown, several hypotheses have been postulated. Our previous research pointed to correlations of hypothalamic metabolic alterations with clinical outcomes of MS, therefore we decided to further test the relationship of these alterations with DGM atrophy. METHODS: We used 1H-Magnetic Resonance spectroscopy (1H-MRS) of the hypothalamus to test its metabolites in 26 patients with RRMS and 22 healthy age-matched controls. DGM atrophy was evaluated by simple planimetry of third ventricular width on the hypothalamic level (3VW) in T1 weighted MRI pictures. Metabolite ratios of N-acetyl aspartate (NAA), choline (Cho), glutamate and glutamine (Glx), myo-inositol (mIns) and creatine (Cr) were correlated with Multiple Sclerosis Severity Scale (MSSS) and 3VW. RESULTS: Metabolite concentrations were compared between patients and controls using multiple regression models allowing for age, 3VW and metabolites. It revealed that the only relevant predictors of MSSS were 3VW and Glx/NAA. At a significance level of P<0.05, a unit increase of 3VW was associated with a 0.35 increase of MSSS, for a typical value of Glx/NAA; P value 0.0039. A unit increase of Glx/NAA was associated with a 0.93 increase of MSSS, for a typical value of atrophy; P value 0.090. There were significant linear correlations between Glx/Cr and MSSS, Glx/NAA and MSSS, and between mIns/NAA and 3VW. CONCLUSIONS: The results suggest that both NAA and Glx are associated with neurodegeneration of hypothalamic DGM and severe disease course. Glx related 1H-MRS parameters seem to be superior to other metabolites in determining disease burden, independently of otherwise powerful 3VW planimetry. Significantly increased mIns/NAA in MS patients compared to controls point to gliosis, which parallels the atrophy of hypothalamic DGM.

Úvod: Matrix metalloproteinázy (MMPs) hrají důležitou roli v imunopatogenezi roztroušené sklerózy (RS ). Významně se podílejí na progresi zánětlivého procesu, porušení hemato-encefalické bariéry, formování zánětlivých RS lézí a demyelinizaci. Jedná se zejména o metalloproteinázu-9 (MMP-9) a metalloproteinázu-2 (MMP-2), exprimované T lymfocyty a monocyty, které jsou převažující populací zánětlivých buněk v aktivních demyelinizačních plakách. V naší předchozí studii jsme prokázali hraniční asociaci polymorfizmu MMP-2-1575G/A s RS . Jiné studie zabývající se vztahem genetických polymorfizmů lokalizovaných v genech pro MMP-2 a tkáňový inhibitor metalloproteinázy- 2 (TIMP-2) s RS dosud nebyly provedeny. Cíl: Cílem práce bylo určit asociační vztah genetických polymorfizmů (–168G/T, –735C/T) lokalizovaných v genu pro MMP-2 a polymorfizmu +853 G/A v genu pro TIMP-2 s vnímavostí k RS ; nalézt možné rozdíly mezi pohlavími a zjistit, zda ovlivňují tíži onemocnění a stupeň postižení. Soubor a metodika: Do studie bylo zařazeno 240 pacientů s RS , diagnostikovanou dle McDonaldových kritérií, kontrolní soubor byl tvořen 135 zdravými jedinci. Klinický stav byl hodnocen pomocí Expanded Disability Status Scale (EDSS ), stupeň postižení byl kvantifikován pomocí Multiple Sclerosis Severity Score (MSSS ). Genotypizace byla provedena metodou polymerázové řetězové reakce a restrikční analýzou. Výsledky: Byla prokázána hraniční asociace v distribuci TIMP-2 +853G/A genetického polymorfizmu s rizikem rozvoje relabující- -remitentní RS (Pg = 0,04), odds ratio (OR ) 1,46; 95% Confidence Interval (CI ): 0,91–2,36). V distribuci ostatních vyšetřených polymorfizmů asociace nalezena nebyla. Nebyl zjištěn rozdíl mezi pohlavími ani asociace s tíží onemocnění. Závěr: Vyšetřené polymorfizmy nejsou rizikovým faktorem vnímavosti k RS v české populaci.
Background: Matrix metalloproteinases (MMPs) play an important role in the immunopathogenesis of multiple sclerosis (MS). They are notable contributors to the progression of inflammatory process, blood-brain barrier disruption, formation of MS lesions and demyelination. The matrix metalloproteinase-9 (MMP-9) and matrix metalloproteinase-2 (MMP-2) are the most important. They are expressed by T-lymphocytes and monocytes, the predominant group of inflammatory cells in active demyelinating plaques. In our previous study, we demonstrated a borderline association of MMP-2-1575G/A gene polymorphism with MS susceptibility. To date, no other genetic association study involving MMP-2 and (tissue inhibitor of metalloproteinases-2 (TIMP-2) genes variability and MS have been carried out. Objective: The aim of this study was to investigate the possible association of MMP-2 (–168G/T, –735C/T) and TIMP-2 (+853G/A) gene polymorphisms with MS susceptibility; to find potential gender differences; and to investigate whether these polymorphisms influence disability. Materials and methods: A study group consisted of 240 patients fulfilling McDonald’s criteria of MS, a control group consisted of 135 healthy volunteers. Clinical status was evaluated with the Expanded Disability Status Scale (EDSS ) and the disease severity was calculated using the MS Severity Score (MSSS ). Polymerase chain reaction (PCR ) methods and restriction analysis were used for genotyping in MMPs genes. Results: We demonstrated a borderline association between TIMP-2 +853G/A gene polymorphism and a risk of developing relapsing-remitting MS (Pg = 0.04), odds ratio (OR ), 1.46; 95% confidence interval (CI ): 0.91–2.36). Other polymorphisms were associated neither with MS susceptibility nor with the disease phenotype. No association with disability was found. Conclusion: MMP-2 and TIMP-2 gene polymorphisms are not a risk factor for MS susceptibility in the Czech population.

BACKGROUND AND OBJECTIVES: The severity of multiple sclerosis (MS) varies widely among individuals. Understanding the determinants of this heterogeneity will help clinicians optimize the management of MS. The aim of this study was to investigate the association between latitude of residence, UV B radiation (UVB) exposure, and the severity of MS. METHODS: This observational study used the MSBase registry data. The included patients met the 2005 or 2010 McDonald diagnostic criteria for MS and had a minimum dataset recorded in the registry (date of birth, sex, clinic location, date of MS symptom onset, disease phenotype at baseline and censoring, and ≥1 Expanded Disability Status Scale score recorded). The latitude of each study center and cumulative annualized UVB dose at study center (calculated from National Aeronautics and Space Administration's Total Ozone Mapping Spectrometer) at ages 6 and 18 years and the year of disability assessment were calculated. Disease severity was quantified with Multiple Sclerosis Severity Score (MSSS). Quadratic regression was used to model the associations between latitude, UVB, and MSSS. RESULTS: The 46,128 patients who contributed 453,208 visits and a cumulative follow-up of 351,196 patient-years (70% women, mean age 39.2 ± 12 years, resident between latitudes 19°35' and 56°16') were included in this study. Latitude showed a nonlinear association with MS severity. In latitudes <40°, more severe disease was associated with higher latitudes (β = 0.08, 95% CI 0.04-0.12). For example, this translates into a mean difference of 1.3 points of MSSS between patients living in Madrid and Copenhagen. No such association was observed in latitudes <40° (β = -0.02, 95% CI -0.06 to 0.03). The overall disability accrual was faster in those with a lower level of estimated UVB exposure before the age of 6 years (β = - 0.5, 95% CI -0.6 to 0.4) and 18 years (β = - 0.6, 95% CI -0.7 to 0.4), as well as with lower lifetime UVB exposure at the time of disability assessment (β = -1.0, 95% CI -1.1 to 0.9). DISCUSSION: In temperate zones, MS severity is associated with latitude. This association is mainly, but not exclusively, driven by UVB exposure contributing to both MS susceptibility and severity.

Pro-inflammatory and anti-inflammatory cytokines have been shown to play a crucial role in the pathophysiology of multiple sclerosis (MS). We investigated the association between interleukin (IL) IL6-174 G/C (rs1800795), IL7RA C/T (rs6897932), and IL-12B A1188C (rs3212227) gene polymorphisms (SNPs) and MS. The study consisted of 297 unrelated MS patients and 135 healthy individuals. In IL6-174G/C (rs1800795), a significant association between the C allele and MS risk [OR 1.41, 95% CI (1.05-1.92); P = 0.025] was found. Carriage of genotypes CC and CG were more common in MS patients [OR 1.58, 95% CI (1.04-2.39); P = 0.031] and also in female MS patients [OR 1.68, 95% CI (1.02-2.79); P = 0.043]. However, after applying Bonferroni's correction the differences did not remain significant. No significant association between the IL7RA C/T (rs6897932) and IL12B A1188C (rs3212227) gene polymorphisms and MS susceptibility was observed. Regarding IL-12B A1188C (rs3212227), a significant association between the CC genotype and MS progression, expressed as MSSS, was demonstrated in the female MS group. Our results indicate that the distribution of IL6-174G/C (rs1800795) SNP was marginally associated with MS susceptibility. We also showed that IL-12B A1188C (rs3212227) can contribute to the progression of the disease in the Czech population.
