Summary of "New therapeutic approaches in progressive multiple sclerosis."

Multiple sclerosis (MS) therapy made huge progress during the last years due to the development of new medications for the relapsing-remitting phase of the disease. The development of therapies for progressive MS was, however, less successful. New medications are the B-cell depleting antibody ocrelizumab, authorized for primary progressive MS with inflammatory activity and the sphingosine-1-receptor modulator siponimod, which is under development for secondary-progressive MS. Pathomechanisms of progressive MS comprise chronic inflammation with activation of T and B cells and microglia with release of reactive oxygen species, age-dependent accumulation of iron and neurodegeneration. In this review, we will discuss the knowledge about the pathogenesis of progression and potential therapeutic approaches in different stages of development.

Medical and Biotech [MESH] Definitions

A form of multiple sclerosis characterized by a progressive deterioration in neurologic function which is in contrast to the more typical relapsing remitting form. If the clinical course is free of distinct remissions, it is referred to as primary progressive multiple sclerosis. When the progressive decline is punctuated by acute exacerbations, it is referred to as progressive relapsing multiple sclerosis. The term secondary progressive multiple sclerosis is used when relapsing remitting multiple sclerosis evolves into the chronic progressive form. (From Ann Neurol 1994;36 Suppl:S73-S79; Adams et al., Principles of Neurology, 6th ed, pp903-914)

An autoimmune disorder mainly affecting young adults and characterized by destruction of myelin in the central nervous system. Pathologic findings include multiple sharply demarcated areas of demyelination throughout the white matter of the central nervous system. Clinical manifestations include visual loss, extra-ocular movement disorders, paresthesias, loss of sensation, weakness, dysarthria, spasticity, ataxia, and bladder dysfunction. The usual pattern is one of recurrent attacks followed by partial recovery (see MULTIPLE SCLEROSIS, RELAPSING-REMITTING), but acute fulminating and chronic progressive forms (see MULTIPLE SCLEROSIS, CHRONIC PROGRESSIVE) also occur. (Adams et al., Principles of Neurology, 6th ed, p903)

A non-glycosylated form of interferon beta-1 that has a serine at position 17. It is used in the treatment of both RELAPSING-REMITTING MULTIPLE SCLEROSIS and CHRONIC PROGRESSIVE MULTIPLE SCLEROSIS.

A rare central nervous system demyelinating condition affecting children and young adults. Pathologic findings include a large, sharply defined, asymmetric focus of myelin destruction that may involve an entire lobe or cerebral hemisphere. The clinical course tends to be progressive and includes dementia, cortical blindness, cortical deafness, spastic hemiplegia, and pseudobulbar palsy. Concentric sclerosis of Balo is differentiated from diffuse cerebral sclerosis of Schilder by the pathologic finding of alternating bands of destruction and preservation of myelin in concentric rings. Alpers' Syndrome refers to a heterogeneous group of diseases that feature progressive cerebral deterioration and liver disease. (From Adams et al., Principles of Neurology, 6th ed, p914; Dev Neurosci 1991;13(4-5):267-73)

Therapeutic approaches that are limited, gradual, or well-established as opposed to radical methods.
