Observation of seleted genes expression in patients with the first attack of neurological symptomatology suspected of multiple sclerosis development before and after the initiation of interferon beta treatment. Efficacy of interferon beta treatment is closely in correlation with expression or inhibition of a group of crucial genes. Correlation between gene expression, clinical effect and MRI changes bring the possibility early to detect non-responsiveness to interferon beta treatment, intesify the therapy and so prevent irreversible damage of the central nervous system. Early nad sufficient multiple sclerosis treatment is the only possible way how to prevent permanent neurological deficit and to preserve patients quality of life.
Sledování exprese vybraných genů u pacientů s první atakou neurologické symptomatologie suspektní z rozvoje sclerosis multiplex před a po zahájení terapie interferonem beta. Účinnost terapie interferonem beta úzce souvisí s expresí či naopak s inhibicí exprese skupiny klíčových genů. Korelace exprese genů s klinickým efektem a MRI vývojem umožní včas odhalit nonresponsivitu na terapii interferonem beta, včas zavést intenzivnější terapii a předejít nevratným škodám na nervové tkáni. Včasná a dostatečná terapie sclerosis multiplex je jedinou možností, jak předejít trvalému neurologickému deficitu a zachovat kvalitu života nemocných.

BACKGROUND AND PURPOSE: Pathologic changes in GM have an important role in MS. We investigated the association between SDGM and cortical volume changes and disability progression in early RRMS. MATERIALS AND METHODS: One hundred eighty patients with RRMS had clinical assessment during 5 years and were divided into those with or without SDP at 5 years by the usual definition in treatment trials. The number of available MR imaging scans at various time points was the following: at baseline, 178; and at 6 months, 172; at 12 months, 175; at 24 months, 155; at 36 months, 160; at 48 months, 158; and at 60 months, 162, respectively. Longitudinal changes in cortical, GM, and WM volume were calculated by using the direct method. RESULTS: At 5 years, 90 patients with RRMS experienced SDP and 90 had stable disease. At baseline, patients with SDP had longer disease duration, greater T2-lesion volume, and smaller whole-brain, WM, cortical, and SDGM volume (P < .01). At 5 years, patients with SDP had significantly greater percentage decreases from baseline compared with those without SDP in the volume of the whole brain (P < .0001), cortex (P = .001), GM (P = .003), and thalamus (P = .01). In patients who developed SDP at 5 years and those who did not, mixed-effect models, adjusted for age, disease duration, and change of the treatment status, showed significant interactions between SDP status at 5 years and changes with time in whole-brain, cortical, lateral ventricle (all P < .001), thalamus (P = .006), and total SDGM (P = .0095) volume. CONCLUSIONS: SDP is associated with progression of cortical, central, and thalamic atrophy in early RRMS during 5 years.

We investigated the evolution of cortical atrophy in patients with early relapsing-remitting (RR) multiple sclerosis (MS) and its association with lesion volume (LV) accumulation and disability progression. 136 of 181 RRMS patients who participated in the Avonex-Steroids-Azathioprine study were assessed bimonthly for clinical and MRI outcomes over 2 years. MS patients with disease duration (DD) at baseline of ≤24 months were classified in the early group (DD of 1.2 years, n = 37), while patients with DD > 24 months were classified in the late group (DD of 7.1 years, n = 99). Mixed effect model analysis was used to investigate the associations. Significant changes in whole brain volume (WBV) (P < 0.001), cortical volume (CV) (P < 0.001), and in T2-LV (P < 0.001) were detected. No significant MRI percent change differences were detected between early and late DD groups over 2 years, except for increased T2-LV accumulation between baseline and year 2 in the early DD group (P < 0.01). No significant associations were found between changes in T2-LV and CV over the followup. Change in CV was related to the disability progression over the 2 years, after adjusting for DD (P = 0.01). Significant cortical atrophy, independent of T2-LV accumulation, occurs in early RRMS over 2 years, and it is associated with the disability progression.

OBJECTIVES: The aim of this study was to explore the evolution of MRI related gender differences in patients with relapsing-remitting (RR) multiple sclerosis (MS) who participated in a clinical trial over the 5 years. METHODS: 181 patients (39 males and 142 females) were assessed for clinical and neuroradiological disease activity over a period of 5 years. Clinical and MRI examination were performed at the baseline, 6, 12, 24, 36, 48 and 60 months. Longitudinal percentage volume changes in whole brain (PBVC), gray matter (PGMVC) white matter (PWMVC) cortex (PCVC), and lateral ventricles (PLVVC) were calculated by using direct methods (SIENA and SIENAX-multitimepoint). Absolute tissue volume changes of subcortical deep GM structures including caudate, putamen, globus pallidus, thalamus, hippocampus, amygdala and nucleus accumbens were estimated using FIRST, a model based segmentation/registration tool. T2 lesion volume (T2-LV) and lesion activity analyses were performed, using a contouring-threshold and subtraction techniques. All clinical and MRI variables were analyzed between males and females. RESULTS: Global (PBVC) and tissue specific (PGMVC, PWMVC, PCVC, PLVVC) brain volume changes showed no significant gender differences over the 5-year follow-up period. Although total subcortical deep GM, caudate, putamen, globus palidus, thalamus and nucleus accumbens normalized volumes were significantly larger in male subjects at baseline, the follow-up analysis showed no differences over the 5 years. There were no gender differences in lesion activity or T2-LV changes over the 5 years. CONCLUSION: No MRI lesion, global, tissue specific or regional brain volume gender change differences were found over the 5-year follow-up.

We report female patient, age 51, with clinically definitive multiple sclerosis (CDMS) since 1998, who underwent two PTA procedures with stent implantation for CCSVI in 2010. Expanded disability status scale (EDSS) worsened since the procedure from 4.5 to 6. Total number of three stents was implanted (two of them in the right internal jugular vein). In six month time, in 2011, patient was referred for independent examination by computer tomography (CT) phlebography for right-sided neck pain. Dislocation of stents on the right side and thrombosis of left sided stent was found. Conservative approach was used so far. Our short report is showing possible complications of PTA and stenting in jugular veins in so called CCSVI and bringing information about neurological state (EDSS) worsening in a subject. Continuation of stent migration in the future is probable, possibly resulting in pulmonary embolism with fatal risk for the patient. We strongly ask for restriction of PTA procedure in so called CCSVI, which concept was not proven to be relevant to MS.

Koncept cerebrospinální žilní insuficience (CCSVI) se v poslední době stal opět studovaným „staronovým“ etiologickým faktorem roztroušené sklerózy. V této práci se autor pokusil shrnout dosavadní znalosti, použité metody a výsledky a přednést kritické připomínky. Dosavadní výzkum a směřování problematiky CCSVI je ukázkou nejenom mylných či neověřených postulátů, ale zejména nesprávného postupu a pořadí jednotlivých kroků klinického výzkumu. Koncept CCSVI nelze ignorovat a je nutné jej studovat i nadále. Nelze však pominout neospravedlnitelnost a chybnou indikaci PTA (perkutánní transluminální angioplastika) a aplikace stentu u žilní insuficience nerespektující charakter a fyziologicko-anatomické zákonitosti žilního řečiště ani povolené indikace „Food and Drug Administration“ (FDA).
The concept of chronic cerebrospinal venous insufficiency (CCSVI) as one of the crucial etiological factors in multiple sclerosis (MS) has begun to emerge recently. This study is a review summarizing all that is known and published about CCSVI, together with the author's long-term experience in the fields of multiple sclerosis and stroke, providing groundwork for critical discussion. In the light of our experience, the concept of CCSVI cannot be ignored and it is essential that extensive future studies into it be performed. We feel that recently-published expectations are overestimated (based upon our own ultrasound examination results in 10 MS subjects and 10 healthy controls). Use of PTA (percutaneous transluminal angioplasty) and stenting as a therapeutical approach in venous insufficiency, without taking physiological and anatomical findings into account, has not to date proved objectively beneficial and is not indicated in MS patients. Neither is it approved by acknowledged authorities such as the Food and Drug Administration of the USA.

Multiple sclerosis is a disease with considerable individual variation, and genetic background plays a key role in disease susceptibility and severity. The objective of the study was to evaluate the relationship between apolipoprotein E (APOE) genotype and the evolution of different clinical and MRI parameters. We investigated a group of 150 relapsingremitting patients that completed 4-year follow-up. The mean age was 30.2 years, disease duration 56.8 months, and baseline Expanded Disability Status Scale (EDSS) 1.8. The changes in brain parenchymal volume (BPV), gray matter (GMV), white matter (WMV) and peripheral gray volume (PGMV) were measured by SIENA/X. T2-lesion volume was assessed by semi-automated methods. The mixed-effect model analysis was used to investigate evolution of clinical and MRI parameters in relation to the APOE ?4 genotype considering two different time models: 4-year follow-up and 15-year period from disease onset. We identified 36 APOE ?4-positive patients. Decline of GMV (P = 0.017), and BPV (P = 0.029) were significantly faster in APOE ?4-positive than in APOE ?4-negative patients in the 15-year model. In the 4- year model, a trend for faster decrease of GMV was found in APOE ?4-positive patients (P = 0.067). No differences in other MRI parameters or EDSS were found between the APOE groups. The results of the study suggest that APOE ?4-positive patients experience faster rate of gray matter atrophy.

BACKGROUND: Studies evaluating interferon beta (IFNbeta) for multiple sclerosis (MS) showed only partial efficacy. In many patients, IFNbeta does not halt relapses or disability progression. One strategy to potentially enhance efficacy is to combine IFNbeta with classical immunosuppressive agents, such as azathioprine (AZA) or corticosteroids, commonly used for other autoimmune disorders. OBJECTIVE: The Avonex-Steroids-Azathioprine study was placebo-controlled trial and evaluated efficacy of IFNbeta-1a alone and combined with low-dose AZA alone or low-dose AZA and low-dose corticosteroids as initial therapy. METHODS: A total of 181 patients with relapsing-remitting MS (RRMS) were randomized to receive IFNbeta-1a 30 microg intramuscularly (IM) once weekly, IFNbeta-1a 30 microg IM once weekly plus AZA 50 mg orally once daily, or IFNbeta-1a 30 microg IM once weekly plus AZA 50 mg orally once daily plus prednisone 10 mg orally every other day. The primary end point was annualized relapse rate (ARR) at 2 years. Patients were eligible for enrollment in a 3-year extension. RESULTS: At 2 years, adjusted ARR was 1.05 for IFNbeta-1a, 0.91 for IFNbeta-1a plus AZA, and 0.73 for combination. The cumulative probability of sustained disability progression was 16.8% for IFNbeta-1a, 20.7% for IFNbeta-1a plus AZA, and 17.5% for combination. There were no statistically significant differences among groups for either measure at 2 and 5 years. Percent T2 lesion volume change at 2 years was significantly lower for combination (+14.5%) versus IFNbeta-1a alone (+30.3%, P < 0.05). Groups had similar safety profiles. CONCLUSION: In IFNbeta-naive patients with early active RRMS, combination treatment did not show superiority over IFNbeta-1a monotherapy.
