Demyelinating Disorders

The common feature of all of the demyelinating diseases is that, initially at least, the oligodendrocyte-myelin unit is the primary target, with the axon comparatively spared. There are a range of causes, both acquired and inherited, which this chapter explores. Multiple sclerosis, the prototypic demyelinating disorder of the central nervous system, is the leading causing of neurological disability among young adults in many industrialized nations. In the last two decades therapies have been licensed with increasing capacity to suppress the inflammation which underlies the condition, leading to durable benefits to patients. The next most prevalent demyelinating disease is neuromyelitis optica. Originally thought to be a variant of multiple sclerosis, it is now recognized to be a distinct disease whose treatment is radically different from multiple sclerosis.

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....

Amino Acids Profile

Multiple sclerosis is the most common demyelinating disease of the central nervous system, affecting mostly young people. There were many risk factors for MS identified, however a direct cause of the disease is still unknown. Pathological changes in the SM lead to the myelin sheath damage around axons, what prevents proper transmission of nerve impulses in the central nervous system. The aim of this study was analyzing and comparing the amino acids profile in the blood serum of MS patients to control group of healthy individuals and evaluating the relationship between them. Significant (p<0.05) differences in the level of glutamate, aspartate and taurine in the blood serum of MS patients were revealed. A positive glutamate and aspartate level correlation in the serum has been demonstrated. Gender is significant only in the case of glutamate level in blood serum. The studies highlight the important role of neurotransmitters in MS and are the initial step in proteomic research.

The Central Nervous System

The most common inflammatory demyelinating disease of the central nervous system is multiple sclerosis, a disabling disorder that affects predominantly young adults between 20 and 50 years old. It affects women twice as often as men. Multiple sclerosis has a complex immunopathogenesis, variable prognosis, and an unpredictable course. Polygenic and environmental (possibly viral) factors probably have a substantial effect on susceptibility to multiple sclerosis.

The article discusses a clinical case of demyelinating disease of the central nervous system, multiple sclerosis in combination with Leber’s hereditary optic atrophy of the optic nerve (Harding syndrome). The debut of the disease at the age of 24 in the form of a simultaneous bilateral decrease in vision, with subsequent atrophy of the optic nerves in both eyes. The diagnosis of multiple sclerosis was confi rmed according to the 2017 McDonald criteria, the diagnosis of Leber’s disease was confi rmed by genetic testing. An important point in the diff erential diagnosis was the identifi cation of the G3460A mutation in the ND1 gene and intrathecal synthesis of oligoclonal immunoglobulin G.

Introduction. Syringomyelia is a cavitary extension inside the spinal cord which can be either symptomatic or congenitally-idiopathic. Syringomyelia during the course of the disease in patients presenting with clinically definite multiple sclerosis was described earlier. Syringomyelia in patients presenting with a clinically isolated syndrome suggestive of multiple sclerosis is unusual. Case Outline. We present two patients presenting with demy-elinating disease of the central nervous system with syringomyelia in the cervical and thoracic spinal cord. We did not find classical clinical signs of syringomyelia in our patients, but we disclosed syringomyelia incidentally during magnetic resonance exploration. Magnetic resonance exploration using the gadolinium contrast revealed the signs of active demyelinating lesions in the spinal cord in one patient but not in the other. Conclusion. Syringomyelia in demyelinating disease of the central nervous system opens the question whether it is a coincidental finding or a part of clinical features of the disease. Differentiation of the significance of syringomyelia finding in these patients plays a role in the choice of treatment concept in such patients.

The Central Nervous System

Multiple sclerosis (MS), a demyelinating disease of the central nervous system, is more commonly seen in women. It has been associated with both anterior and intermediate uveitis as well as retinal vasculitis. Ocular inflammation may develop concurrent with, prior to, or after the development of neurologic signs and symptoms. Patients with MS have an approximately 1% chance of developing intraocular inflammation. Patients with intermediate uveitis have an 8–12% risk of being diagnosed with MS. This risk is higher in females and in those with bilateral disease. This should be kept in mind when evaluating patients with uveitis, particularly in those patients for whom TNF inhibitor therapy is being considered, as these agents may worsen demyelinating disease.

Multiple sclerosis (MS) is the major inflammatory demyelinating disease of the central nervous system. There is strong evidence that an immune response in the brain is a critical component of the disease. In 1992, in a collaboration between academia and biotechnology, my colleagues and I showed that α4 integrin was the critical molecule involved in the homing of immune cells into the inflamed brain. Was it sheer luck that these results led to the development of a drug for MS?

Cholinergic Markers

Multiple sclerosis (MS) is an autoimmune and demyelinating disease of the central nervous system. Although the etiology of MS is still unknown, both genetic and environmental factors contribute to the pathogenesis of the disease. Acetylcholine participates in the modulation of central and peripheral inflammation. The cells of the immune system, as well as microglia, astrocytes and oligodendrocytes express cholinergic markers and receptors of muscarinic and nicotinic type. The role played by acetylcholine in MS has been recently investigated. In the present review, we summarize the evidence indicating the cholinergic dysfunction in serum and cerebrospinal fluid of relapsing–remitting (RR)-MS patients and in the brains of the MS animal model experimental autoimmune encephalomyelitis (EAE). The correlation between the increased activity of the cholinergic hydrolyzing enzymes acetylcholinesterase and butyrylcholinesterase, the reduced levels of acetylcholine and the increase of pro-inflammatory cytokines production were recently described in immune cells of MS patients. Moreover, the genetic polymorphisms for both hydrolyzing enzymes and the possible correlation with the altered levels of their enzymatic activity have been also reported. Finally, the changes in cholinergic markers expression in the central nervous system of EAE mice in peak and chronic phases suggest the involvement of the acetylcholine also in neuro-inflammatory processes.

Demyelinating Process

Aims and background Classical multiple sclerosis plaques usually have typical features on gadolinium-enhanced MRI scan. This non-neoplastic demyelinating process of the central nervous system generally does not produce focal space-occupying lesions associated with ring enhancement. However, atypical appearance of demyelinating lesions simulating a brain tumor is a possible well-known phenomenon. Methods We present our experience with 4 cases of multiple sclerosis indistinguishable clinically and neuroradiologically from a cerebral tumor. All patients underwent surgery. Results Histological examinations of all cases were positive for multiple sclerosis plaques. Conclusions The presented cases demonstrate the importance of considering a demyelinating disease in the differential diagnosis of a tumor-like brain lesion.
