I knew it was going to be one of those days as soon as I opened my eyes. I woke in some sort of half-start, my eyelids popping abruptly open as I looked up at the ceiling. Something seemed…
The number, location, and size of lesions can help predict the risk of progression from clinically isolated syndrome (CIS) to multiple sclerosis (MS) within one year, a new study shows. The study, “MRI in predicting conversion to multiple sclerosis within 1 year,” was published in the journal…
Quanterix’s ultra-sensitive Simoa assay has the potential to open new uses for the brain biomarker known as neurofilament light chain, including the possibility to detect early evidence of neurological diseases like multiple sclerosis (MS), Parkinson’s, and Alzheimer’s, and ably evaluate efforts to treat and prevent them, the company…
Smoking increases the relapse rate in patients with relapsing-remitting multiple sclerosis being treated with Tysabri , an observational study suggests. Multiple sclerosis is a multifactorial disease associated with both genetic and environmental risk factors. Smoking, in particular, has been linked to numerous aspects of MS, including its development and progression. In a previous study, the research team looked at how smoking influences the relapse rate in RRMS patients being treated with interferon beta. From more than 800 patients, they found that smoking one pack per day (about 20 cigarettes) essentially interfered with the positive effect of the IFN-beta treatment and increased the relapse rate by 27%. The researchers then questioned whether the same was true for other treatments. Tysabri, developed by Biogen, is a monoclonal antibody that targets the alpha-4 integrin protein. By interfering with this molecule, the therapy prevents white blood cells from moving into the central nervous system, suppressing the immune reaction that contributes to MS symptoms. In the study, 355 Tysabri-treated RRMS patients from the Danish Multiple Sclerosis Centre were assessed. To gather information on smoking habits and body mass index, the patients filled out a 100-question survey. Data was collected between the start of the treatment and a two-year follow-up visit. Results showed that smoking one pack of cigarettes per day increases the relapse rate by 38% in RRMS patients on Tysabri. This increase in relapse rate takes into account both sex and age at the start of treatment, since age can affect the relapse rate. For example, an increase in age by one year raises the number of relapses by 2%. The researchers also looked at the relationship between smoking and the presence of two immune-related alleles: HLA-DRB1*15:01 and HLA-A*02:01. Previous studies showed that HLADRB1*15:01 is associated with an increased risk of developing MS, while HLA-A*02:01 is linked to a decreased risk. Although previous studies reported a link between smoking and these two alleles in MS patients, the current study did not find an association between smoking and carrying either of these alleles. Based on the results, the researchers concluded that smoking significantly increases the relapse rate in RRMS patients receiving Tysabri. According to the team, the results "add important information that hopefully will sharpen the focus on the overall harmful effects of smoking in MS patients."

Downbeat, but Upbeat
Most weeks with MS are downbeat. That’s hardly a way to capture a reader’s attention — all of us struggle. What we need is light to blow away the shade. Last night as I climbed the stairs to bed, my legs gave out with three stairs to go. Luckily,…
Higher-than-usual levels of specific antibodies in the blood of patients with clinically isolated syndrome (CIS) may predict a faster progression to multiple sclerosis (MS), an Australian study reports. The specific antibody is known as IgG3, an immunoglobulin known to promote inflammation. The study, “Higher Serum Immunoglobulin G3 Levels May Predict…
Tune into the World and See
As I pulled into the overcrowded Trader Joe’s parking lot, I was grateful to see an open handicapped space. Once parked, I turned off the car engine and paused; the heat was oppressive. Ten days post-chemo/Solu-Medrol (methylprednisolone) and my fatigue was as thick as the stagnant humidity. I…
There are many things that confuse me, particularly in the medical area. Perhaps that’s why I am more comfortable thinking about MS patients’ quality of life rather than being into the hard science of medicine and understanding how medicines work. I’m thinking in particular of botulinum toxin, more…
Loss of health-related quality of life is caused mostly by balance problems, muscle stiffness, and depression in people with relapsing-remitting multiple sclerosis (RRMS), and for those with progressive MS, the causes are muscle rigidity, paralysis, weakness, and pain, according to a…
Pregnancy, including successful delivery or miscarriage, worsens symptoms of multiple sclerosis (MS), as well as onset of the disease, a retrospective study shows. Researchers found the same effect of pregnancy on neuromyelitis optica spectrum disorders (NMOSD), an inflammatory disorder of the central nervous system characterized by demyelination and damage of…
Leaving a restaurant the other evening, I was stepping off an unusually high curb. Right cane down, left cane down, swing the right leg, swing the left leg, and … uh-oh. Down I go. I’d been asking for it. I’d needed to change the electrodes on the Bioness…
The Graduate
The queue to get into Canterbury Cathedral in bright sunshine seems endless. The quandary of being Dracula strikes me — I’ll either fry in the sun or fry in a church set up during the Roman occupation of Britain! Luckily my condition is MS, so we seek solace…
