A bacterial toxin in the gut — specifically, the epsilon toxin produced by Clostridium perfringens bacteria in the intestinal tract — may be a key environmental driver of multiple sclerosis (MS), according to a recent study. After finding the toxin at a higher abundance in the fecal samples of MS…

People who had infectious mononucleosis — a contagious disease for which the Epstein-Barr virus (EBV) is the leading cause — had a higher incidence of multiple sclerosis (MS) in the 10 years following diagnosis compared with individuals not diagnosed with the virus, a study found. This link was particularly…

Infection with the common Epstein-Barr virus (EBV) increases the risk of developing multiple sclerosis (MS) by 32 times — the strongest link yet — according to a study looking at two decades of data from more than 10 million U.S. military members. “The hypothesis that EBV causes MS has been…

The upcoming Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) 2021 Forum will focus on the spectrums of multiple sclerosis (MS), related inflammation, disease severity, and the latest findings in the field. According to an ACTRIMS press release, about 1,000 researchers and clinicians are expected to…

A comparison of immune cells isolated from identical twins — in which only one of each pair was diagnosed with multiple sclerosis (MS) — identified a population of immune-regulating T-cells present in those with asymptomatic brain inflammation, a study has found. …

NICE Postpones Final Opinion on Adding Ocrevus to Public Health System for PPMS Patients in UK This last-minute reprieve from the agency that dictates which medications may be prescribed for patients of the U.K.’s National Health Service (NHS) is welcome news. Last summer, the National Institute for…

Children exposed to certain air pollutants in urban areas or some household chemicals are at higher risk of developing multiple sclerosis (MS) during childhood or adolescence, two new research studies suggest. The studies “Urban air quality and associations with pediatric multiple sclerosis” and…

The Americas Committee for the Treatment and Research in Multiple Sclerosis, otherwise known as ACTRIMS, says its third annual ACTRIMS Forum will take place Feb. 1-3, 2018, at the Hilton San Diego Bayfront in San Diego, California. These forums bolster the ACTRIMS mission, which is to foster the careers of young researchers interested in MS by promoting mentor relationships with senior scientists, and giving promising investigators a chance to present their early research findings. ACTRIMS 2017 was a record-breaking year with over 800 people attending. Organizers say 1,000 people will attend this year's conference. The 2018 forum's theme is “Therapeutic Targets in MS: The Frontier and the Future of Disease Modifying Therapy.” ACTRIMS 2018 also features continuing medical education credits for attendees, as well as participation grants for applicable young investigators.

Air pollution, particularly tiny inhalable particles around 10 micrometers in diameter, is a likely trigger for relapses in multiple sclerosis patients, a French study reports. The study, “Air pollution by particulate matter PM10 may trigger multiple sclerosis relapses,” was published in the journal Environmental Research. A growing number of epidemiological studies suggest…

The absence of epigenetic factors in myelin-producing oligodendrocyte cells make sure that myelin production is switched off in the adult brain. Targeting these factors may be a way of triggering myelin regeneration in multiple sclerosis (MS), and a step toward personalized medicine for this disease, Dr. Patrizia Casaccia said in a talk…

Multiple sclerosis (MS) is thought to be caused by genetic factors, but environmental cues are increasingly recognized to have an impact on disease onset and development. One environmental factor suggested to play a role in MS is infectious agents, such as viruses. Now, different teams of scientists have explored the…

Exposure to heavy metals and being female are associated with a higher incidence of multiple sclerosis (MS), according to a study conducted by Maria Cristina Monti and colleagues from two Italian universities. The study, “Is Geo-Environmental Exposure a Risk Factor for Multiple Sclerosis? A Population-Based Cross-Sectional Study in South-Western Sardinia,” was…

The Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) recently announced that its second annual ACTRIMS Forum will be at the Omni ChampionsGate Feb. 23-25, 2017, in Orlando, Florida. ACTRIMS Forum 2017 promises to be of value to physicians, scientists, researchers, analysts, faculty, and allied health…

Fecal samples from a group of people with relapsing-remitting multiple sclerosis (RRMS) showed evidence of a different gut microbiota than that found in healthy controls, and may be a non-genetic reason for the altered immune system responses seen in MS patients. The study, “Multiple sclerosis patients have…

According to new research published in the Multiple Sclerosis Journal, environmental factors appear to play a much greater role in the onset of multiple sclerosis (MS) than previously recognized. The study, “Ethnicity and prevalence of multiple sclerosis in east London,” was led by scientists at…

Three parallel sessions concerning multiple sclerosis (MS) prevention, clinical phenotypes and magnetic resonance imaging (MRI) were featured at the 31st Congress of the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), recently held in Barcelona, Spain (October 7 – 10, 2015). The first parallel session was entitled “Will MS…

Exposure to sunlight may delay the development of multiple sclerosis (MS), according to a new study from researchers in Denmark. The work, titled “Association between age at onset of multiple sclerosis and vitamin D level–related factors,” appeared October 7, 2015 in the journal Neurology.
