Plegridy is a pegylated form of interferon beta. Pegylation is a process, used by several other non-MS medications, whereby a long string of polyethylene glycol molecules is attached to the interferon beta molecule, to extend its half-life by reducing clearance via kidneys or other elimination pathways in the body. This modification allows less frequent dosing of Plegridy – once every two weeks – although it is still administered as an injection under the skin.
In the ADVANCE trial, Plegridy was ..
In a recent collaborative study completed by the Swedish Multiple Sclerosis Center, University of Washington, and University of Wisconsin, doctors discovered through a more refined magnetic resonance imaging (MRI) process, the amount of myelin lost in the gray matter of multiple sclerosis (MS) patients’ brains may indicate a more severe form of the disease.
Multiple Sclerosis (MS) has long ...
At this year’s North American Neuro-ophthalmology Society meeting, data was presented on another technique that is being developed and refined for use in the MS population, a questionnaire about visual quality of life. The ..
No treatments can currently abate the advanced stage of the disease, known as secondary progressive MS, which gradually causes patients to become more disabled. Statins are postulated to have immunomodulatory effects that appear to be independent of their effect on cholesterol. A benefit has been suggested in early multiple sclerosis (MS) based on reduction of magnetic resonance imaging brain lesions. However, following trials have had inconsistent results.
In this multicenter, double-blind study, investigators randomized 140 participants with secondary progressive (SP) MS to 80 mg of simvastatin or placebo daily for 2 years. Participants were 18 to 65 years old, had active progression over the preceding 2 years, and had difficulties ambulating but were not wheelchair bound. Whole brain atrophy was 43% slower annually in simvastatin recipients than in placebo recipients. The simvastatin group also had small clinical improvements over placebo on the disability scale and a patient-reported MS impact scale at 24 months.
These findings show that simvastatin reduced ...
A guideline was recently published about the use of complementary and alternative medicine in multiple sclerosis (MS).
The guideline process involves identifying all of the scientific articles about potential therapies and evaluating them based on their scientific merits. The evaluation process follows a strict set of requirements related to the conduct of the research.
The review included a wide variety of complementary and alternative therapies that have been proposed for MS. Not surprisingly, most therapies did not have sufficient scientific data to determine whether or not they were effective. Some cannabinoid preparations (marijuana extracts) were shown to be effective, primarily for spasticity. This reflects a relatively large number of studies done with these compounds and the availability of a commercially available extract in some countries. A handful of therapies were shown to be ineffective. Most therapies had insufficient studies to determine their effectiveness.
The importance of this review is that it ...
The benefits of exercise and being physically fit is what many people strive for. However, a recent study added a new dimension to what exercise can do to enhance health. In other words, exercise did more than keep a body fit. It also made study participants think better. You may ask, why is this new information important?
Cognitive impairment is one of multiple scleroris (MS) ’s most disabling features and it can affect between 22% to 60% of people living with the disease. Cognitive deficits may include problems with: slower information processing speed; memory impairment; difficulty with new learning and executive functioning. Historically, medical and rehabilitation approaches to the problem have been inconsistent in improving cognition.
The new frontier of exercise for improved cognition provides hope. This study’s objective was to determine if there was an association between improvements in objective measures of physical fitness and performance on cognitive tests.
Participants were people with MS who participated in a telephone based health promotion intervention, chose to work on exercise, and who completed pre and post intervention assessments. Participants were then measured for strength, aerobic fitness, and cognition at baseline and 12 weeks later.
After controlling for variables such as age, gender, MS disease activity, MS type, etc. there was evidence suggesting that cognitive functioning changed over time based on level of fitness. Participants in the physically improved group showed improved performance on measures of executive functioning after 12 weeks of exercise. The results of this study add support to the hypothesis that change in fitness is associated with improved executive functioning in people with MS. The desired outcomes are that improved cognition correlates with better quality of life, activities of daily living, vocational endeavors, and rehabilitation measures.
Where do we go from here? Since less is known about exercise training and cognition in MS (compared to studies demonstrating aerobic and strength training significantly improving cognitive functioning in older adults and people with mild cognitive impairment), we need more studies to examine this relationship in the MS population.
A recent study looked at ..
