relapse

The European Commission has approved Merck KGaA’s Mavenclad (cladribine tablets) to treat highly active relapsing forms of multiple sclerosis (MS). The Aug. 25 decision in Brussels marks the first approval of a highly efficient oral short course therapy for MS in Europe. Mavenclad has been shown to harness disease activity for…

Coming down with the flu can provoke relapses in multiple sclerosis patients by activating glial cells that surround and protect nerve cells. In a study in mice, scientists found that activated glial cells increase the levels of a chemical messenger in the brain that, in turn, triggers an immune reaction and, potentially, autoimmune attacks. The flu is caused by the human influenza virus and, despite being unpleasant, usually resolves itself within days. However, for people with MS and other neurological conditions, the flu can lead to disease relapse. Researchers at the University of Illinois investigated what happens in the brain of MS patients during upper-respiratory viral infections, such as the flu. "We know that when MS patients get upper respiratory infections, they're at risk for relapse, but how that happens is not completely understood," Andrew Steelman, an assistant professor at the university and the study's senior author, said in a press release. "A huge question is what causes relapse, and why immune cells all of a sudden want to go to the brain. Why don't they go to the toe?" The team used a mouse model characterized by autoimmune responses within the brain and spinal cord — the type of deregulated immune responses seen in MS patients. Researchers infected the animals with a version of human influenza virus adapted to mice, and looked at changes that occurred in the animal’s central nervous system. While the virus was never detected in the animals' brains, upon infection some of the mice developed MS-like symptoms. "If you look at a population of MS patients that have symptoms of upper respiratory disease, between 27 and 42 percent will relapse within the first week or two," Steelman said. "That's actually the same incidence and timeframe we saw in our infected mice, although we thought it would be much higher given that most of the immune cells in this mouse strain are capable of attacking the brain." The team then investigated how a peripheral influenza infection could contribute to disease onset. They infected a wild-type (normal) strain of mice with the flu virus and looked at alterations in the brain and spinal cord. Scientists found that infection increased the activation of glial cells in the mice's brains. Moreover, it induced infiltration of several immune cells — T-cells, monocytes and neutrophils — into the brain within eight hours of infection. Overall, these findings suggest that the chemokine CXCL5 plays a key role in mediating an autoimmune attack in MS, and might be explored for therapeutic potential.

Multiple sclerosis (MS) patients who used the RebiSmart (Merck Serono) device to inject themselves with interferon beta-1a (INF β-1a) did an excellent job of sticking to their treatment timetable without skipping treatments, according to a study. They also had a lower annual disease relapse rate and more relapse-free periods,…

Twenty years ago, the idea that B-cell depletion could treat multiple sclerosis would have been greeted with a hearty laugh by any well-respected neurologist or MS researcher — or perhaps a scoff. But times change and research advances. Today, a medicine that gets rid of certain B-cells may be the most powerful drug yet developed against…

When describing a multiple sclerosis exacerbation (also called a relapse, attack, or flare-up), comparing it to a home’s circuit panel is a good analogy to use. When a fuse blows on the circuit board the power is interrupted. During an MS attack, the myelin sheath that covers nerve axons…
