#ACTRIMS2022 – Algorithm Predicts Relapse Risk Using EHR Data

Using a two-step machine learning strategy, researchers have developed an algorithm to predict the risk of multiple sclerosis (MS) relapse based on data gleaned from electronic health records. “The two-step machine learning model predicts a patient’s future one-year MS relapse risk with clinically actionable accuracy, comparable to other clinical…

#ACTRIMS2022 – In New Mouse Model, Evobrutinib Shows Efficacy

Researchers developed a new mouse model that more closely captures a specific type of inflammation characteristic of progressive multiple sclerosis (MS) — and found, in experiments, that treatment with an oral medication called evobrutinib can lessen disease activity. This new mouse model may help scientists in MS to better study…

Eating Beans, Vegetables May Reduce MS Risk

Eating a lot of green leafy and other vegetables, beans, nuts and berries seems to significantly lower the likelihood of developing multiple sclerosis (MS), according to a study from Iran. The findings also suggest that the chances of developing the disease may be higher in people who eat more…

Vumerity Added to NHS of Scotland for People With Active RMMS

Note: An earlier version of this story stated the Scottish Medicines Consortium approved Vumerity for RRMS patients in that country. The consortium decides to add a medicine to Scotland’s National Health Service; the MHRA approves treatments for England, Scotland, and Wales. The Scottish Medicines Consortium has approved adding the…

Atara, Fujifilm Enter Deal to Produce Cell Therapies

Atara Biotherapeutics has reached an agreement with Fujifilm Diosynth Biotechnologies for the production of its cell therapy pipeline, including ATA188, an experimental therapy being investigated for the treatment of progressive multiple sclerosis (MS). Under the agreement, Fujifilm will acquire Atara’s T-Cell Operations and Manufacturing (ATOM) facility in Thousand…

How Vitamin D Modulates Immune System Activity Detailed in Study

Vitamin D can influence the immune system’s tolerance to certain proteins by changing how DNA is packaged in specific immune cells called dendritic cells, according to a new study. Its findings could have implications for treating diseases like multiple sclerosis (MS) that are characterized by the immune system attacking…

Study Explains How Epstein-Barr Virus Infection Could Cause MS

Similarities between an Epstein-Barr virus (EBV) protein and a brain protein called GlialCAM may explain why EBV infection increases the risk of multiple sclerosis (MS), results from a new study show. Due to the structural resemblance of the two proteins, B-cells — a type of immune cell that is critical…

Imaging Brain Metabolites May Help Diagnose, Monitor MS

A new imaging technique called magnetic resonance spectroscopic imaging, or MRSI, could be useful for diagnosing and monitoring multiple sclerosis (MS), according to a small study. “If confirmed in longitudinal clinical studies, this new neuroimaging technique could become a standard imaging tool for initial diagnosis, for disease progression and…

Study Probes Why Some Don’t Experience Placebo Effect

Differences in the physical architecture of the brain may explain why some people with multiple sclerosis (MS), but not others, experience a placebo effect, according to a new study. The results suggest that MS itself may make some individuals unable to experience the benefits of a placebo. “Our findings…

Acthar Gel May Help RRMS Patients Who Fail Corticosteroids

Acthar Gel (repository corticotropin injection) may be useful for managing disease relapses in people with relapsing-remitting multiple sclerosis (RRMS) who fail to respond to treatment with corticosteroids, according to results from a small clinical trial. The study, “Results from a multicenter, randomized, double-blind, placebo-controlled study…
