 My Progressive MS Moment of Truth

“If I were you two, I think I’d plan for the worst,” Amy, my physiatrist, said to my wife and me as we sat in the examination room. It was just after 11 a.m. on Friday, Jan. 18. January has become one of two pivotal months in terms of…

New Study Supports Hitting MS Fast and Hard

The question of how quickly to start a disease-modifying therapy (DMT) after a multiple sclerosis (MS) diagnosis is one that I frequently see when I browse online. It goes hand in hand with questions about which DMT is best to start with. There are many things to consider when…

Gilenya Better at Lowering Relapse Rate than Tecfidera or Aubagio, Study Suggests

Gilenya is linked to significantly lower annualized relapse rates in relapsing-remitting multiple sclerosis (RRMS) patients compared to Tecfidera or Aubagio, a study suggests. All three therapies showed similar effects on disability outcomes. Oral immunotherapies — including Novartis’ Gilenya, Biogen’s Tecfidera, and Sanofi Genzyme’s Aubagio — are currently standard therapies for RRMS treatment. But while these therapies are highly effective at modulating MS activity, studies comparing their efficacy on relapse and disability are missing. This is an important point for MS patients, so that if a change in oral therapies is needed (due to lack of tolerance, for example), the decision on a more suitable therapy is based on scientific evidence. To address this matter, a group of researchers used the MsBase, an international observational MS cohort study, to identify RRMS patients who had been treated with Gilenya, Tecfidera, or Aubagio for at least three months. The team compared Tecfidera versus Aubagio, Gilenya versus Aubagio, and Gilenya versus Tecfidera, specifically for the therapy’s impact on relapse activity, six-month disability worsening or improvement, and persistence of treatment. Relapse was defined as the occurrence of new symptoms or exacerbation of existing ones for a period of over 24 hours, at least 30 days after a previous relapse. Disability was assessed using the Expanded Disability Status Scale (EDSS); the six-month disability worsening or improvement were defined as an increase or a decrease by one value in EDSS. The study included 614 patients treated with Aubagio, 782 with Tecfidera, and 2,332 with Gilenya. Patients were followed over a median of 2.5 years. Patients’ characteristics at baseline differed among the three groups. Aubagio-treated patients tended to be older, with longer periods of disease, fewer relapses, and lower EDSS scores compared to the other two groups. Patients treated with Gilenya had higher EDSS and more relapses during the prior year, compared to those treated with Tecfidera. The majority of the patients had been treated with other immunotherapies prior to being given one of these three oral treatments. Results showed that Gilenya-treated patients had significantly lower annualized relapse rates than those treated with Tecfidera (0.20 versus 0.26) or Aubagio (0.18 versus 0.24), while patients taking either Tecfidera or Aubagio had a similar rate. However, during the 2.5-year period analyzed, researchers found no differences in disability accumulation or disability improvement among the three therapies. Regarding treatment persistence, Tecfidera and Aubagio were more likely to be discontinued than Gilenya. Overall, the results suggest that treatment with Gilenya may have a greater impact on relapse frequency in RRMS patients compared to Tecfidera and Aubagio, although the "effect of the three oral therapies on disability outcomes was similar during the initial 2.5 years on treatment," researchers said. “Choosing a therapy in individual patients remains a complex task that requires thorough and individualized evaluation of disease prognosis, and the corresponding risks and benefits of the increasing number of available therapies,” they concluded.

Funding Supports MS Research on Epigenetics and Fatigue in Australia

Australian researchers from the University of Newcastle and the Hunter Medical Research Institute (HMRI) have received funding for two projects that will study unexplored areas in multiple sclerosis (MS). The projects, investigating the role of epigenetic differences in MS severity and treatment against MS-derived fatigue, received $211,000 AUD (about $151,300…

Altered Oligodendrocyte Diversity Contributes to Multiple Sclerosis, Study Suggests

Subpopulations of oligodendrocytes — cells that produce the myelin sheath that protects nerve fibers — are altered in patients with multiple sclerosis, a study shows. These findings suggest that oligodendrocyte diversity and the different functions of these subpopulations might have a greater role in the disease than previously thought. The severity of MS varies greatly, and the patient's disability level does not correlate well with the degree of myelin loss. This suggests that other factors contribute to MS severity. One such factor may be that oligodendrocytes are heterogeneous — diverse in makeup and function. For example, oligodendrocytes in mouse spinal cords are known to naturally produce longer myelin sheaths than oligodendrocytes in the mouse brain. Additionally, individual oligodendrocytes have been shown to have different molecular makeups. However, the extent of human oligodendrocyte diversity and its possible contribution to MS pathology remains unknown. Researchers from the Karolinska Institutet and the MRC Centre for Regenerative Medicine studied the differences of individual human oligodendrocytes from healthy and MS brains to assess their diversity. Specifically, the team examined oligodendrocytes from the white matter areas of post-mortem human brains both from MS and non-MS patients. The team examined the RNA content — the messenger molecule carrying instructions from DNA for the production of proteins — from individual oligodendrocytes. Researchers identified groups of RNA molecules that defined features of oligodendrocytes from healthy human white matter. Some of these groups match those that defined oligodendrocytes in healthy mice. Strikingly, some of these RNA molecules in healthy brains were under-represented in oligodendrocytes from MS brains, whereas others were more prevalent. “We found that oligodendrocytes are a diverse population of cells and that different types are likely to have different functions in the brain,” Charles ffrench-Constant, the study's co-lead author, said in a Karolinska Institutet news release written by Katarina Sternudd. These differences in oligodendrocyte RNA content may indicate different functional states of oligodendrocytes in MS lesions. “The proportions of different resident oligodendrocytes in the lesions are changed, along with their properties, suggesting that they might have important roles in MS,” said Eneritz Agirre, PhD, a study co-author. Furthermore, the researchers believe that this altered diversity in oligodendrocytes in MS may be important to understand disease progression and develop therapeutic approaches. “Understanding which types of oligodendrocytes are most beneficial in repairing myelin will be crucial for maximizing the chances of developing much-needed treatments for MS,” said Anna Williams, PhD, study co-lead author. The team concluded that the changes in different oligodendrocyte subpopulations in MS suggest "a more complex role of these cells in the pathology of the disease, but also in regeneration of new cells,” said Gonçalo Castelo-Branco, PhD, another study co-lead author.

Study of Myelin Debris Sheds Light on Brain Inflammation in MS

Endothelial cells, those lining the inside of small blood vessels, promote clearance of myelin debris — a common detrimental outcome of demyelinating diseases such as multiple sclerosis (MS) or spinal cord injury. However, in its path to clear the brain from myelin debris, endothelial cells trigger more damaging mechanisms, promoting…

Recognizing Pseudo Exacerbations in MS

My readers have recently brought something to my attention: They informed me that not all MS exacerbations (flare-ups, relapses, and attacks) are created equal. I have learned that along with the hardcore types, which usually require steroid treatment, there are also pseudo-exacerbations. I can always trace the causes of…
