Therapeutic management of severe relapses in multiple sclerosis

Current Treatment Options in Neurology
Carolyn Bevan, Jeffrey M Gelfand

Abstract

While not all multiple sclerosis (MS) relapses require treatment, relapses that are bothersome or that impair function should prompt consideration of timely treatment to restore function and minimize disability. Patients with suspected MS relapses should be evaluated to confirm the diagnosis, exclude other causes of neurological dysfunction, and identify potential triggers for relapse or pseudo-relapse, such as urinary tract infections, fever, or metabolic derangements. The diagnosis of an MS relapse is clinical, but MRI may be useful for confirmation and to evaluate for multifocal disease activity. High-dose oral or intravenous glucocorticoids, with or without an oral taper, are first-line therapy for MS relapses. Adrenocorticotropic hormone (ACTH) provides an alternative to glucocorticoid treatment but is currently much more expensive and does not have proven superiority. If the acute neurological deficits remain severe after steroid treatment, and particularly if there is persistent abnormal contrast-enhancement of the symptomatic lesion on repeat MRI, plasma exchange (PLEX) should be considered as an acute rescue therapy for relapse. In exceptional cases, particularly fulminant or tumefactive disease that fails to improve f...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
