[Therapeutic effect of encapsulated into the nanocontainers MBP immunodominant peptides on EAE development in DA rats].

Multiple Sclerosis (MS) is a serve autoimmune neurodegenerative disease. Development of innovative approaches of MS treatment is of a high priority in the modern immunology and pharmacy. In the present study we showed high therapeutic efficiency of immunodominant peptides of myelin basic protein (MBP) incorporated into the monolayer mannosylated liposomes on the development of experimental autoimmune encephalomyelitis (EAE) in DA rats. MBP is a component ofoligodendrocytes' membrane, which form axonal sheath, and is one of the major autoantigens in MS. We analyzed binding pattern ofanti-MBP autoantibodies from MS patients using previously designed MBP epitope library. Utilizing the same approach we investigated pool of anti-MBP antibodies from SJL/J and C57/BL6 mice and DA rats with induced EAE. The most relevant rodent model to MS was EAE in DA rats according to the autoantibodies' binding pattern. We selected three immunodominant MBP fragments encapsulated in monolayer mannosylated liposomes for the following treatment of verified DA rodent model. MBP fragment 46-62 was the most effective in reducing of the first EAE attack, whereas MBP 124-139 and 147-160 inhibited development of pathology during remission stage. Simultaneous administration of these peptides in liposomes significantly decreased level of anti-MBP antibodies. Synergetic therapeutic effect of MBP fragments reduced integral disease score by inhibiting first EAE wave and subsequent remission, thus, our findings disclosure novel approaches for efficient treatment of Multiple Sclerosis.

[Atypical multiple sclerosis - Balo's concentric sclerosis: two case-reports and a review]. / Atipichnyi rasseiannyi skleroz - kontsentricheskii skleroz Balo: dva klinicheskikh nabliudeniia i obzor.

This article presents two clinical cases of patients diagnosed with Balo's concentric sclerosis. Distinctive features of the pathogenesis in the aspect of differential diagnosis from other forms of multiple sclerosis and possible treatment are discussed.

[Comparative, placebo-controlled clinical study of efficacy and safety of glatiramer acetate 20 mg in patients with relapsing-remitting multiple sclerosis: results of the first year of the study]. / Sravnitel'noe platsebo-kontroliruemoe klinicheskoe issledovanie effektivnosti i bezopasnosti preparatov glatiramera atsetata 20 mg u patsientov s remittiruyushchim rasseyannym sklerozom: rezul'taty pervogo goda nablyudeniya.

The article presents the results of international multicenter randomized double-blind, active and placebo-controlled, comparative phase 3 trial. The goal of the study was to demonstrate non-inferiority of BCD-063 (glatiramer acetate, manufactured by JSC «BIOCAD¼, Russia) to copaxone-Teva (Teva Pharmaceutical Enterprise Co., Ltd., Israel) in patients with relapsing-remitting multiple sclerosis. METHODS: 158 patients with relapsing-remitting multiple sclerosis were randomly assigned into 3 groups: BCD-063, copaxone-Teva and placebo, at a ratio of 2:2:1, respectively. RESULTS AND CONCLUSION: Efficacy analysis after 48 weeks of therapy demonstrated no differences between BCD-063 group and copaxone-Teva group in both MRI parameters and frequency of relapses. The mean (SD) of number of MRI-confirmed relapses per patient per year (the primary endpoint) in BCD-063 group was 0.098361 (0.351422), in copaxone-Teva group - 0.098361 (0, 351 422) and in placebo group - 0.178571 (0.390021). There were also no differences between the groups for all other efficacy parameters (EDSS and MSFC). Both investigational BCD-063 and copaxone-Teva demonstrated a favorable safety profile. The data obtained from the present study confirm the therapeutic equivalence of BCD-063 (CJSC BIOCAD, Russia) and copaxone-Teva, that is important for further implementation of glatiramer acetate generic in the clinical practice of multiple sclerosis therapy.

[Epstein-Barr virus in the pathogenesis of multiple sclerosis (a review)]. / Virus Épshteina-Barr v patogeneze rasseiannogo skleroza (obzor).

Multiple sclerosis is now regarded as a disease, which is based on genetic predisposition. Trigger mechanism are various exogenous factors. The Epstein-Barr virus is thought to be a trigger. This report provides information about possible mechanisms of the influence of the Epstein-Barr virus on the development of multiple sclerosis.

[Efficacy and tolerability of long-term using of glatimer acetate (copaxone): a 10 year-study in the Moscow Municipal Multiple Sclerosis center].

Experience of 10-year administration of glatimer acetate (copaxone) in 74 patients with active remitting multiple sclerosis is summarized. The significant decrease in the frequency of exacerbations was seen over these ten years. Disease severity on the EDSS was stable and decreased only to the end of the 10-year period. The positive stable clinical dynamics did not depend on the disease severity at baseline. The drug was well-tolerated that allowed to control the course of multiple sclerosis: 64.8% of patients had no more than one exacerbation over 10 years and in 71.6% patients, the disease progression was absent or minimal (less than one score on EDSS). It has been concluded, that the long-term 10-year treatment with copaxone enables to control the development of disease in many patients.

[Results of a comparative clinical trial of the Russian Β - interferon-1b bioanalogue (infibeta)].

Results of annual comparative clinical research of the Russian biosimilar of beta-IFN - 1в at 122 patients with multiple sclerosis are presented. There were positive dynamics on EDSS scores in both groups (in the main group and group of control) in a year of treatment. There were positive dynamics in frequency of relapses in the main group (with 1.5 to 0.4 in a year) and in group of control (with 1.4 to 0.37 in a year). Positive dynamics according to MRI was also fixed in both groups. In both groups, good tolerability of the treatment was noted. This research didn't reveal essential distinctions on efficiency and safety parameters in both groups.

[Instrumental methods of the rehabilitation of motor disorders in patients with multiple sclerosis].

Motor and coordination disorders are the most prominent clinical presentations of multiple sclerosis. Currently, good results were achieved in the pathogenetic treatment of the disease. However methods of treatment of motor and coordination disorders are not widely used. The positive experience in the treatment of motor disorders using the apparatus Moto-med is presented. The use of this treatment led to positive changes in the state of motor functions, i.e. the decrease of neurologic deficit and improvement of quality of life, of patients.
