Demyelinating Disorders

In a retrospective review of patients with acquired demyelinating disorders of the central nervous system, 133 patients (5.6%) whose diseases started in childhood, were selected from 2369 patients, who had medical records in the Neurology Department of Dokuz Eylul University. Out of 133, 98 had relapsing remitting multiple sclerosis, 21 had secondary progressive multiple sclerosis, 8 had clinically isolated syndrome, 3 had neuromyelitis optica, 2 had Marburg disease, and 1 had radiologically isolated syndrome. In 55 patients (41.3%), disease onset was before age 16. Polysymptomatic presentation (22.6%) was the most common initial feature. The EDSS scores ranged from 0 to 9 with a median of 2.0 () for 126 patients. MRI records of 111 patients were obtained. 97 patients had clinically definite multiple sclerosis. 11 MS patients (11.3%) did not initially present the diagnostic MRI features. All of the remaining multiple sclerosis patients fulfilled Barkhof-Tintore criteria (100%) and 88.7% fulfilled KIDMUS criteria. Cranial MRI of NMO patients was normal. Our findings demonstrate some important clinical and paraclinical features that can help the literature on acquired demyelinating disorders of childhood by utilizing data from Western Turkey.

Demyelinating Disorders

The spectrum of central nervous system demyelinating disorders is vast and heterogeneous and, often, with overlapping clinical presentations. Misdiagnosis might occur in some cases with serious therapeutic repercussions. However, introduction of several new biomarkers such as aquaporin-4 IgG and myelin oligodendrocyte glycoprotein IgG has made distinction between diseases such as multiple sclerosis and myelin oligodendrocyte glycoprotein antibody-associated disorder easier. Here, we report a case of a 15-year-old male patient with subacute multifocal neurological presentation without encephalopathy, eventually diagnosed as myelin oligodendrocyte glycoprotein antibody-associated disorder.

Chemokine Receptor Gene

Multiple sclerosis is chronic inflammatory disease of the central nervous system in the development of which chemokines of the type Tx1 play the leading role. Chemokines and their receptors participate in the development of multiple sclerosis as a result of drawing immune cells into central nervous system. Mutation of CCR5 delta32 decreases functional activity of the appropriate receptor on cellular surface and thus can reduce migration of leucocytes into foci of injury. Aimed at studying the role of mutation in multiple sclerosis, we compared frequency of gene type CCR5 in peripheral mononuclears of 102 multiple sclerosis patients and in 136 healthy subjects. The results obtained allow to conclude that polymorphism of chemokine receptor gene CCR5del32 is not a leading factor in the susceptibility to multiple sclerosis in the studied population.

Clinicians suspect demyelination when episodes reflecting damage to white matter tracts within the central nervous system occur in young adults. The paucity of specific biological markers of discrete demyelinating syndromes places an emphasis on clinical phenotype—temporal and spatial patterns—when classifying demyelinating disorders. The diagnosis of multiple sclerosis, the most common demyelinating disorder, becomes probable when these symptoms and signs recur, involving different parts of the brain and spinal cord. Other important demyelinating diseases include post-infectious neurological disorders (acute disseminated encephalomyelitis), demyelination resulting from metabolic derangements (central pontine myelinosis), and inherited leucodystrophies that may present in children or in adults. Accepting differences in mechanism, presentation, and treatment, two observations can usefully be made when classifying demyelinating disorders. These are the presence or absence of inflammation, and the extent of focal vs. diffuse demyelination. Multiple sclerosis is prototypic for the former, whereas dysmyelinating disorders, such as leucodystrophies are representative of the latter....

Multiple Sclerosis Study Group

Background: There has been tremendous growth in research in pediatric multiple sclerosis (MS) and immune mediated central nervous system demyelinating disorders since operational definitions for these conditions were first proposed in 2007. Further, the International Pediatric Multiple Sclerosis Study Group (IPMSSG), which proposed the criteria, has expanded substantially in membership and in its international scope. Objective: The purpose of this review is to revise the 2007 definitions in order to incorporate advances in delineating the clinical and neuroradiologic features of these disorders. Methods: Through a consensus process, in which input was sought from the 150 members of the Study Group, criteria were drafted, revised and finalized. Final approval was sought through a web survey. Results: Revised criteria are proposed for pediatric acute disseminated encephalomyelitis, pediatric clinically isolated syndrome, pediatric neuromyelitis optica and pediatric MS. These criteria were approved by 93% or more of the 56 Study Group members who responded to the final survey. Conclusions: These definitions are proposed for clinical and research purposes. Their utility will depend on the outcomes of their application in prospective research.

The Impact

Background: The multifunctional cytokine interleukin-6 (IL-6) is involved in inflammatory processes in the central nervous system. It is well documented that amount of IL-6 is increased in serum, cerebrospinal fluid and central nervous system lesions of patients with multiple sclerosis. A single nucleotide polymorphism at position -174 in the IL-6 gene promotor appears to influence IL-6 expression. Recently, several researchers have focused on HLA-DRB alleles, specifically HLA-DRB1*1501, as a potential risk allele in the pathogenesis of multiple sclerosis. Objective: To investigate the possible influence of IL-6/-174 polymorphisms on susceptibility to multiple sclerosis and its integration with HLA-DRB1*1501. Genomic DNA was extracted from whole blood of 345 patients with multiple sclerosis and 426 control subjects. Method: The SSP-PCR method was used to determine genotypes and Fisher’s exact test was applied to determine differences between groups. HLA-DRB1*1501 was observed more frequently among multiple sclerosis patients compared with healthy subjects (45% and 34%, respectively; OR = 1.6, 95% CI = 1.2—2.2, p = 0.0018). At the IL-6/-174 position, the G allele had higher frequency among multiple sclerosis patients compared with controls (77% and 70%, respectively; OR = 1.4, 95% CI = 1.1—1.8, p = 0.0038). This difference was more significant among HLA-DRB1*1501-positive patients and controls (81% and 67%, respectively; OR = 1.9, 95% CI = 1.5—2.5, p < 0.0001). Results: Our results have shown that the G allele at the IL-6/-174 promoter polymorphism may be associated with development of multiple sclerosis in this population, and may be strengthened by HLA-DRB1*1501. Conclusions: We suggest more studies to confirm these results in other populations.

Intrathecal immunoglobulin synthesis in an oligoclonal pattern is the most common immunologic abnormality detected in MS patients. Various treatments, such as immunomodulators and immunosuppressors, have not been found to modify it. Natalizumab hinders migration of encephalitogenic T-cells into the central nervous system (CNS), reducing inflammatory response. Its impact on CSF oligoclonal bands (OCBs) has not been demonstrated. This report describes its effect in four out of six patients with multiple sclerosis after a mean of 10 infusions: the CSF was negative for OCBs at the second lumbar puncture. In conclusion, natalizumab treatment can reduce CSF OCBs to undetectable levels, although the clinical significance of this observation is not yet known.
