Mesenchymal stem cell therapy shows potential: Study review

Mesenchymal stem cell (MSC) therapy is safe and well tolerated, and leads to improvements in disability and a reduction in lesion burden in people with multiple sclerosis (MS), according to a review of published studies. MSC treatments also reduced levels of biomarkers associated with nerve damage and inflammation,…

Hormone therapy may boost disease activity in older MS men

Older men with multiple sclerosis (MS) who use medicines that reduce the levels of androgens, or male sex hormones, experience sustained or increased disease activity instead of the expected decreases that typically happen with advancing age, a small study suggests. According to the team, such disease activity was “particularly”…

Gum disease may accelerate MS progression, mouse study suggests

Gum disease caused by the bacterium Porphyromonas gingivalis (Pg) is associated with worse multiple sclerosis (MS) in a mouse model of the disease, a study shows. Infection with Pg directly or indirectly boosted pro-inflammatory pathways in immune cells in the spleen, where they’re produced, thereby aggravating MS. These effects…

Experimental MS therapy safely repairs myelin sheath in animals

An experimental medicine, 2-D08, boosts motor function in mice and primate models of multiple sclerosis (MS) by repairing the myelin sheath, the protective coating on nerve fibers that’s damaged in people with the neurodegenerative condition, a study showed. 2-D08 also outperformed the approved therapy dalfampridine, sold as Ampyra…

Antihistamine clemastine may worsen MS disease progression

Clemastine fumarate, an antihistamine, boosted disease progression by more than five times in adults with progressive multiple sclerosis (MS), according to data from a Phase 1/2 trial. “Likely nobody in the MS field, us included, knew about this potential [clemastine] toxicity until we collected the data presented here,” the…

Thyroid hormone FT4 may play role in development of MS

The thyroid hormone thyroxine, or FT4, may play an indirect role in the development of multiple sclerosis (MS), which seems to be mediated by certain immune cells, a study suggests. “Future investigations should explore how these immune cells modulate MS onset and progression in the context of thyroid…

Cleveland Clinic wins funds to compare RRMS treatment strategies

The Patient-Centered Outcomes Research Institute (PCORI) has awarded the Cleveland Clinic $6.7 million to identify optimal treatment strategies for people with relapsing-remitting multiple sclerosis (RRMS). The funds will support the extension study of the multicenter DELIVER-MS (NCT03535298) clinical trial. The study is comparing two MS treatment approaches…

Gene variant plus mono raises MS risk: Large-scale study

The risk of multiple sclerosis (MS) is significantly higher in people who carry a variant of the HLA gene called HLA-E*01:01 and have a history of infectious mononucleosis (mono), the manifestation of an Epstein-Barr virus (EBV) infection, according to a study based on U.K. Biobank data. The higher…

Tysabri infusion improves working ability for RRMS patients: Study

One year of Tysabri (natalizumab) treatment improves working ability among people with relapsing-remitting multiple sclerosis (RRMS), according to new data from TITAN, an observational study by researchers in France that assessed the impact of the infusion therapy. Use of the approved therapy resulted in improvements across several parameters:…

Secondary contaminants from PCBs linked to higher MS risk in study

A group of manufactured chemicals called hydroxylated polychlorinated biphenyls, or OH-PCBs, which persist in the environment despite a ban on production, are associated with an increased risk of developing multiple sclerosis (MS), according to a new study. In turn, another family of compounds highly resistant to environmental breakdown, called…

Brain stimulation with cognitive training fails to lower MS fatigue

A noninvasive brain stimulation technique called transcranial direct current stimulation (tDCS) doesn’t seem to ease fatigue in adults with multiple sclerosis (MS) when given at home with computer-based cognitive training, according to one of the largest studies of its kind. While the home-based intervention was deemed feasible, combining daily…

MS patients highly satisfied with Sensoready autoinjector pen

Nearly all adults with relapsing forms of multiple sclerosis (MS) said they are highly satisfied with the Sensoready autoinjector pen to self-administer Kesimpta (ofatumumab), according to a recent U.S. survey. High satisfaction was mainly driven by the reasonable administration time and ease of use, the researchers said. The…

Men who started on high-efficacy DMTs had fewer relapses: Analysis

Men with multiple sclerosis (MS) who started on high-efficacy disease-modifying therapies (DMTs) experienced significantly fewer relapses than those who started with moderate-efficacy DMTs, according to real-world claims analysis involving more than 10,000 U.S. patients. “No significant difference in relapse was found among females,” researchers wrote. “This observation highlights…

Exercise in MS eases fatigue, improves muscular fitness: Analysis

Exercise effectively reduces fatigue and improves muscular fitness in people with multiple sclerosis (MS), though the optimal exercise type and dose differ for each outcome, according to a meta-analysis of published studies involving more than 3,500 patients. Mind-body exercise, which combines physical movement, mental focus, and controlled breathing, was…

Severe COVID-19 may double risk of MS: Swedish study

Hospitalization for severe COVID-19 is significantly associated with a twofold higher risk of developing multiple sclerosis (MS), according to a study involving nearly the entire population of Sweden. No increased risk of MS was found among those who tested positive for SARS-CoV-2, the virus that causes COVID-19, or received…

Nerve stimulation for bladder issues also can make sex more enjoyable

Percutaneous tibial nerve stimulation (PTNS), a nonsurgical treatment that delivers mild electrical impulses to a nerve in the ankle, significantly reduced bladder activity and improved sexual function for women with relapsing-remitting multiple sclerosis (RRMS), according to a clinical trial. While PTNS is designed to modulate neural mechanisms involved in…

DMTs have slowed RRMS disability progression rate: Analysis

The rate of disability progression among people with relapsing-remitting multiple sclerosis (RRMS) has slowed over the years due to advances in disease-modifying therapies (DMTs), according to a long-term analysis. Patients diagnosed in recent decades have experienced fewer progression events associated with relapses, called relapse-associated worsening (RAW), and also…

Researchers find sulfuretin molecule may promote myelin repair

Researchers at the Oregon Health & Science University have discovered a plant-derived small molecule that can promote the growth of cells that produce myelin, the protective coating around nerve fibers that’s damaged in multiple sclerosis (MS). The naturally occurring molecule, sulfuretin, blocks the activity of an enzyme that…
