While pregnancy does not appear to affect the disease course of multiple sclerosis (MS), questions remain about the best time to stop or resume treatment before conception and after delivery, the safety of new medications, and the importance of family planning. Pregnancy was the “hot topic” discussion today…

An amino acid change to phenylalanine, and a specific class I HLA gene variant are associated with greater risk for multiple sclerosis (MS), according to a study in Japanese patients. Researchers also identified an HLA variant, or mutation, associated with neuromyelitis optica spectrum disorder (NMOSD), an autoimmune condition…

No excessive relapse risk appears to exist for people with multiple sclerosis who undergo surgery that requires anesthesia, researchers report, challenging long-held assumptions associated with MS and surgery. Their single-site study, “Multiple sclerosis relapse risk in the postoperative period: Effects of…

Routine screening through magnetic resonance imaging (MRI) of people with multiple sclerosis (MS) can predict long-term disease progression — leading to more certainty and informing better treatment choices, a 15-year study reported. The study, titled “Early imaging predictors of long-term…

The percentage of Taiwanese who develop multiple sclerosis (MS) after an episode of clinically isolated syndrome (CIS) is lower than that reported for other ethnicities, and those who do progress are likely to have a milder disease course, a study found, supporting how factors like geography and genetics…

People with multiple sclerosis (MS) may have a greater overall risk of developing cancer than the general population, according to the results of a 58-year follow-up study of nearly 7,000 patients in Norway. Risk seems particularly high for cancers in respiratory organs, urinary organs, and the central nervous system.

Merck KGaA presented new evidence supporting the safety and clinical efficacy of Rebif (interferon beta-1a) for relapsing-remitting multiple sclerosis (RRMS) at the 5th Congress of the European Academy of Neurology (EAN), June 29–July 2 in Oslo, Norway. The company, known as EMD Serono in the U.S. and Canada, presented 16…

New research suggests that rising blood pressure might be predictive of intracranial hemorrhage — bleeding in the brain, a serious and sometimes fatal condition — in people with multiple sclerosis (MS) who are receiving treatment with Lemtrada (alemtuzumab). The study, titled “Intracerebral haemorrhage during…

Scientists are zeroing in on mutations in a few genes that appear to be major risk factors for developing multiple sclerosis (MS). The results of their research suggest there are common biological pathways that cause the disease. The study, “Exome sequencing in multiple sclerosis families identifies 12…

New data suggests that treatment with Tysabri (natalizumab) in an extended interval dosing regimen is associated with a significantly lower risk of progressive multifocal leukoencephalopathy (PML) in patients with multiple sclerosis (MS), compared with the standard interval dosing. The data was presented by Lana Zhovtis Ryerson, MD, on May 7 at the 2019 …

New research suggests that even though pregnant women with multiple sclerosis (MS) are often viewed as high risk by their physicians, pregnancy  does not seem to increase the likelihood of adverse obstetrical outcomes for those patients or their babies. The research was presented at the 2019 Annual Meeting…

The amount of zinc, iron, and other minerals a person has in his or her diet is not associated with the risk of developing multiple sclerosis (MS), according to a study. The study, “Total intake of different minerals and the risk of multiple sclerosis,” was published…

Body mass index (BMI), but not the age at which people start puberty, could increase the risk of multiple sclerosis (MS), a study suggests. The study, “Effect of age at puberty on risk of multiple sclerosis: A mendelian randomization study,” was published in the journal …

Treatment of relapsing multiple sclerosis (MS) with beta-interferon therapies is associated with extended patient survival, particularly if taking such treatments for more than three years, according to a real-world study in Canada and France.
