A common misconception is that any attack of CNS demyelination means a diagnosis of acute MS. When a patient has a first attack of demyelination, the physician should not rush to diagnose MS, because the differential diagnosis includes a number of other diseases. In the United States, various disease-modifying agents for MS are currently approved for use in relapsing MS. Loss of myelin is demonstrated in this chronic plaque. Examination of the demyelinating lesions in the spinal cord and brain of patients with MS shows myelin loss, destruction of oligodendrocytes, and reactive astrogliosis, often with relative sparing of the axon cylinder. In some MS patients, however, the axon is also aggressively destroyed.

The location of lesions in the CNS usually dictates the type of clinical deficit that results. As neural inflammation resolves in MS, some remyelination occurs, but some recovery of function that takes place in a patient could be due to nervous system plasticity. MS is also characterized by perivenular infiltration of lymphocytes and macrophages, as demonstrated in the image below. These infiltrates are composed of activated T cells, B cells, and macrophages. One of the earliest steps in lesion formation is the breakdown of the blood-brain barrier. Enhanced expression of adhesion molecules on the surface of lymphocytes and macrophages seems to underlie the ability of these inflammatory cells to penetrate the blood-brain barrier.

High field MRI in the diagnosis of multiple sclerosis: high field, mS have spinal cord lesions at some point during the course of the disease. 13 Department of Neurology, and Implementation Subcommittee of the American Academy of Neurology.

In fact, variable degrees of antibody-producing plasma cell infiltration have been demonstrated in MS lesions. The image below provides an overview of demyelination. 12, a potent promoter of inflammation, is expressed at high levels in lesions that form early in MS. B7-1, a molecule required to stimulate lymphocytes to release proinflammatory cytokines, is also expressed at high levels in early MS plaques. T cells that can be identified by their expression of a transcription factor known as Foxp3. Conversely, the cytokine IL-23 has been shown to drive cells to commit to a pathogenic phenotype in autoimmune diseases, including MS. Tregs and TH 17 cells are not the only critical immune cells in the pathogenesis of MS. B cells are gaining increased attention by MS researchers.

MS have spinal cord lesions at some point during the course of the disease. No strong correlation has been established between the extent of the plaques and the degree of clinical disability. The gray matter may be involved. It is marked by demyelination of the spinal cord and cerebral cortex but not of cerebral white matter. Researchers studied the brain and spinal cords from 100 patients with MS who had died between May 1998 and November 2012. ON during the course of their disease. The combination of optic neuritis and longitudinally extensive spinal cord lesions constitutes Devic neuromyelitis optica. Different variants of genes normally found in the general population, commonly referred to as polymorphisms, may lead to different gradations of cellular expression of those genes and therefore of the proteins that they encode.

Life expectancy is shortened only slightly in persons with MS, 5 National Multiple Sclerosis Society, comparison of MRI criteria at first presentation to predict conversion to clinically definite multiple sclerosis. FDA approves third oral agent for MS. Which some authors suggest is modestly to strongly predictive of disability progression, and the survival rate is linked to disability.

The disease follows a relapsing — and cladribine are also approved for active secondary progressive disease. Recommended diagnostic criteria for multiple sclerosis: guidelines from the International Panel on the diagnosis of multiple sclerosis. In some MS patients, t cells in secondary progressive multiple sclerosis.

MS will be of great interest to the clinicians treating this complex disorder in the early stages. To date, however, HLA-DRB1 is the only chromosomal locus that has been consistently associated with MS susceptibility. 05 allele confers protection against MS. Molecular mimicry has been proposed as an etiologic process in MS. The molecular mimicry hypothesis refers to the possibility that T cells in the peripheral blood may become activated to attack a foreign antigen and then erroneously direct their attack toward brain proteins that share similar epitopes. A virus that infects cells of the immune and nervous systems can possibly be reactivated periodically and thus lead to acute exacerbations in MS. MS has been difficult to prove. EBV might help trigger some cases but not others, making associations in populations difficult. Environmental factors Geography is clearly an important factor in the etiology of MS. The incidence of the disease is lower in the equatorial regions of the world than in the southernmost and northernmost regions.

However, a systematic review by Alonso and Hernán found that this latitude gradient became attenuated after 1980, apparently due to an increased incidence of MS in lower latitudes. Apparently, whatever environmental factor is involved must exert its effect in early childhood. If an individual lives in an area with low incidence of MS until age 15 years, that person’s risk remains low even if the individual subsequently moves to an area of high incidence. Therefore, the exact role played by geography versus genetics is not clear. Vitamin D levels Low levels of vitamin D have been proposed as one environmental factor contributing to the development of MS. D appear to be associated with a reduced risk of MS. This hypothesis would also provide an explanation for the correlation between childhood sun exposure and MS in monozygotic twins discordant for MS.

Chronic cerebrospinal venous insufficiency A controversial hypothesis proposes a vascular rather than an immunologic cause for some cases of MS. The CCSVI hypothesis posits that stenosis of the main extracranial venous outflow pathways results in compromised drainage and a high rate of cerebral venous reflux. The CCSVI hypothesis has been linked with the potential effects of iron deposition in the brain parenchyma, which some authors suggest is modestly to strongly predictive of disability progression, lesion volume accumulation, and atrophy in some patients with MS. A small, open-label study suggested that internal jugular vein and azygous vein angioplasty had a positive effect on MS symptoms in patients with CCSVI. A meta-analysis found a positive association between CCSVI and MS, but poor reporting of the success of blinding and marked heterogeneity among studies of CCSVI precluded definitive conclusions. See FDA issues alert on potential dangers of unproven treatment for multiple sclerosis. Given the paucity of supporting evidence, most MS experts also question the CCSVI hypothesis and do not recommend this therapy.

Nevertheless, CCSVI has received widespread attention in the lay press and MS support groups, so physicians should be prepared for inquiries from patients on this highly controversial subject. The CDC concluded that the weight of the available scientific evidence does not support the suggestion that hepatitis B vaccine causes or worsens MS. People with MS should not be denied access to health-preserving and potentially-life saving vaccines because of their MS, and should follow the CDC guidelines for any given vaccine. According to the National Multiple Sclerosis Society, 400,000 individuals in the United States are affected by MS. As is true of autoimmune diseases in general, MS is more common in women. The female-to-male ratio of MS incidence has increased since the mid-20th century, from an estimated 1. The average age at diagnosis is 29 years in women and 31 years in men. 1 million people are affected by MS. The disease is seen in all parts of the world and in all races, but rates vary widely.

The presence of these exceptions implies that racial and ethnic differences affect risk. In addition, a substantial increase in MS incidence has been reported from different regions, suggesting that environmental factors, as well as geographic and genetic ones, play an important role in MS. Epidemiologic studies indicate an increase in MS prevalence in Latin America. MS apparently does not occur in Amerindians with Mongoloid genes. Detailed examination of these patients in many instances reveals some degree of cognitive deterioration. Male patients with primary progressive MS have the worst prognosis, with less favorable response to treatment and rapidly accumulating disability. The higher incidence of spinal cord lesions in primary progressive MS is also a factor in the rapid development of disability.
