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.

And Oxidative Stress

Multiple sclerosis (MS) exhibits many of the hallmarks of an inflammatory autoimmune disorder including breakdown of the blood-brain barrier (BBB), the recruitment of lymphocytes, microglia, and macrophages to lesion sites, the presence of multiple lesions, generally being more pronounced in the brain stem and spinal cord, the predominantly perivascular location of lesions, the temporal maturation of lesions from inflammation through demyelination, to gliosis and partial remyelination, and the presence of immunoglobulin in the central nervous system and cerebrospinal fluid. Lymphocytes activated in the periphery infiltrate the central nervous system to trigger a local immune response that ultimately damages myelin and axons. Pro-inflammatory cytokines amplify the inflammatory cascade by compromising the BBB, recruiting immune cells from the periphery, and activating resident microglia. inflammation-associated oxidative burst in activated microglia and macrophages plays an important role in the demyelination and free radical-mediated tissue injury in the pathogenesis of MS. The inflammatory environment in demyelinating lesions leads to the generation of oxygen- and nitrogen-free radicals as well as proinflammatory cytokines which contribute to the development and progression of the disease. Inflammation can lead to oxidative stress and vice versa. Thus, oxidative stress and inflammation are involved in a self-perpetuating cycle.

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.

The Brain

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.
