[Differential diagnosis of multiple sclerosis in children]. / Differentsial'naya diagnostika rasseyannogo skleroza u patsientov detskogo vozrasta.

At the onset, multiple sclerosis (MS) in children is characterized by a phase of active inflammation with extensive demyelination of the white matter of the CNS, which often mimics this nosology with a whole spectrum of inflammatory demyelinating diseases such as ADEM, anti-MOG encephalitis, ONMSD. In order to formalize the diagnostic process, the International Pediatric Multiple Sclerosis Study Group (IPMSSG) proposed diagnostic criteria for the main immune-mediated demyelinating diseases of the CNS in children, which, in theory, should simplify the diagnostic search. However, in practice, the range of nosologies in the course of differential diagnosis is much wider and often it is not possible to establish an unambiguous diagnosis in the early stages. The authors analyze their own clinical observations based on a sample of 100 pediatric patients with a referral diagnosis of «MS?¼ and describe a clinical case of the onset of highly active MS with an assessment of the dynamics of the clinical and paraclinical course of the disease.

[The results of an open comparative retrospective trial of the course of multiple sclerosis during treatment with infibeta and other interferon-beta bioanalogues and glatiramer acetate]. / Rezul'taty otkrytogo sravnitel'nogo retrospektivnogo issledovaniia osobennostei rasseiannogo skleroza na fone terapii preparatom infibeta i drugimi bioanalogami interferonov beta i glatiramera atsetatom.

AIM: To evaluate the efficacy and safety of the interferon beta-1b bioanalogue 'infibeta' in the treatment of multiple sclerosis (MS) in comparison with other interferon beta bioanalogues and the generic drug glatiramer acetate. MATERIAL AND METHODS: The data of 500 patients with MS treated with different disease-modifying drugs were analyzed. Patients of group 1 (n=95) received infibeta; group 2 (n=108) interferon beta-1b; group 3 (n=83) genfaxon-44; group 4 (n=109) sinnovex; group 5 (n=105) aksoglatiran FS. RESULTS: In all groups, there was a significant decrease in the AARR and an increase in the EDSS score (p<0,05) after 12 and 24 months of treatment (p<0,05) with the best indicators in groups 1-3. After 12 months of treatment, the number of patients without signs of MRI activity was higher in groups 1-3 (48-61%) than in groups 4 and 5 (47, 43%, respectively) (p>0,05). After 24 months of treatment, the number of patients without signs of MRI activity decreased to 41-46% in groups 1-3, and more significantly in group 4 (27%). The percentage of NEDA-3 achieving patients did not significantly differ in the groups (23-32%) after 12 months of treatment. After 24 months of treatment the NEDA-3 declined more in group 4 (19%), least of all in groups 1 and 2 (27, 25%, respectively) (p>0,05). In most cases, the observed adverse events were mild or moderate. Flu-like syndrome was observed rarely in groups 1 and 4 (p<0,05). Injection reactions were observed most commonly in groups 3 and 5 (p<0,05). CONCLUSION: Infibeta, while retaining all the advantages of high-dose interferon beta, has the best tolerability profile, which makes it one of the optimal first line disease-modifying therapy for treatment of patients with MS.

[Effect of cerebrolysin on remyelination processes in multiple sclerosis patients in stage of relapse regression]. / Primenenie tserebrolizina u bol'nykh rasseyannym sklerozom v stadii regressa obostreniya.

AIM: To evaluate the efficacy and safety of Cerebrolysin (EVER Neuro Pharma GmbH, Austria) in the treatment of patients with multiple sclerosis (MS) in stage of relapse regression. MATERIAL AND METHODS: The study involved 40 patients with remitting MS (McDonald criteria 2010) in stage of MS relapse regression after pulse therapy with methylprednisolone 1000 mg/day 5. Patients randomized into 2 groups: group 1 (G1, n=20) received cerebrolysin 20 ml per 200 ml of 0.9% NaCl solution 1 times per day 10; Group 2 (G2, n=20) - only 200 ml 0.9% NaCl solution on analogical scheme. All patients before and 3-4 weeks after the treatment were carried out assessment of vital signs, routine laboratory tests, tests of cognitive-motor functions (SDMT), visual acuity (LCAT), a comprehensive neurophysiological examinations (CNE). 4 patients in the G1 with presence of previously identified G+ lesions (G+L) were conducted MRI of brain after 3-4 weeks after treatment. RESULTS: In G1 the average age of the patients was 27.35 (5.65) years, the ratio of M/F - 40/60%, the duration of the disease 29.9 (11.01) months, the EDSS in relapse stage - 3.5 [2.0; 4.5] points. The average age of patients in G2 was 26.65 (4.93) years, the ratio of M/F - 35/65%, the duration of the disease - 30.25 (11.98) months, the EDSS in relapse stage - 3.0 [1.5; 4.5] points. Clinical relapse of MS was categorized into groups as follows: optic neuritis (15% vs. 30%; p=0.26), stem dysfunction (15% vs. 25%; p=0.43), hemispheric dysfunction (50% vs. 35%; p=0.34), transverse myelitis (20% vs. 10%; p=0.38). 17 patients (85%) in G1 and 18 patients (90%) in G2 completed a full course of treatment. In both groups showed significant regression estimation EDSS (2.0 [1.75; 2.5] vs. 2.5 [1.75; 2.5]), while significant intergroup differences were not found (p=0.665). In G1 was noted more pronounced dynamics of performance improved in testing MSFC and SDMT (p=0.038 and p=0.026, respectively). Significant intergroup differences in the dynamics of improvement VCAT values were not found (p=0.658). Also in G1 was revealed greater regression of total variance in the CNE than G2 (70.59% vs. 27.78%, p=0.028), while in almost all cases the previously identified neurophysiological abnormalities are not completely regressed. In addition to G1 was marked a tendency to reduce of progressive deterioration of CNE indicators (10% vs. 30%; p=0.228). On MRI cerebrolysin treatment was not associated with an increase of G+L (G+L number before treatment in 4 patients - 14, after treatment - 12), which indicates a potential anti-inducing effect of the drug on the intrathecal inflammation in MS. CONCLUSION: Cerebrolysin positive role in the stimulation of remyelination process in MS has been confirmed by CNE and the selected treatment regimen has demonstrated its safety. Effect of the drug appear to be due to its composition: so according to a group of authors found that investigated the drug contained fragments of tubulin, actin and myelin basic protein, all of which is necessary to ensure non-specific trophic regenerated CNS myelin sheath.

[Clinical, neurophysiological and neuroimaging study of tremor in multiple sclerosis]. / Klinicheskoe, neirofiziologicheskoe i neirovizualizatsionnoe izuchenie tremora pri rasseiannom skleroze.

OBJECTIVE: To identify clinical types of tremor in multiple sclerosis (MS) and clarify their pathophysiological mechanisms. MATERIAL AND METHODS: We examined 124 patients with MS, including 58 patients with tremor, using clinical (digital spiralography), neurophysiological (tremor electromyography, visual and sensory evoked potentials, transcranial magnetic stimulation with tremor resetting, long latency reflexes, electroencephalography) and neuroimaging (MRI, morphometry) methods. RESULTS AND CONCLUSION: Five main variants of tremor were identified: distal postural and postural-intention (variant 1), distal intention (variant 2), proximal and distal intention and postural-intention (variant 3), Holmes (variant 4), axial (variant 5). Postural tremor (variants 1, 3) and rest tremor (variant 4) are caused by the central oscillators. Intention tremor (variants 2, 3), postural-intention tremor (variant 4), axial (variant 5) are caused by the pathology of cerebellar feedback loops. Clarification of mechanisms for the development of tremor in MS allowed to develop a scheme of differential treatment.
