Health Literacy and Outcomes in Multiple Sclerosis.

Health literacy is an important consideration when managing patients with multiple sclerosis. Literacy impacts comprehension about patient condition, participation in medical decision making, and compliance with treatment plans. Awareness of health literacy allows clinicians to tailor their approach to individual patients and improve the overall care of patients.

Summary of comprehensive systematic review: Rehabilitation in multiple sclerosis: Report of the Guideline Development, Dissemination, and Implementation Subcommittee of the American Academy of Neurology.

OBJECTIVE: To systematically review the evidence regarding rehabilitation treatments in multiple sclerosis (MS). METHODS: We systematically searched the literature (1970-2013) and classified articles using 2004 American Academy of Neurology criteria. RESULTS: This systematic review highlights the paucity of well-designed studies, which are needed to evaluate the available MS rehabilitative therapies. Weekly home/outpatient physical therapy (8 weeks) probably is effective for improving balance, disability, and gait (MS type unspecified, participants able to walk ≥5 meters) but probably is ineffective for improving upper extremity dexterity (1 Class I). Inpatient exercises (3 weeks) followed by home exercises (15 weeks) possibly are effective for improving disability (relapsing-remitting MS [RRMS], primary progressive MS [PPMS], secondary progressive MS [SPMS], Expanded Disability Status Scale [EDSS] 3.0-6.5) (1 Class II). Six weeks' worth of comprehensive multidisciplinary outpatient rehabilitation possibly is effective for improving disability/function (PPMS, SPMS, EDSS 4.0-8.0) (1 Class II). Motor and sensory balance training or motor balance training (3 weeks) possibly is effective for improving static and dynamic balance, and motor balance training (3 weeks) possibly is effective for improving static balance (RRMS, SPMS, PPMS) (1 Class II). Breathing-enhanced upper extremity exercises (6 weeks) possibly are effective for improving timed gait and forced expiratory volume in 1 second (RRMS, SPMS, PPMS, mean EDSS 4.5); this change is of unclear clinical significance. This technique possibly is ineffective for improving disability (1 Class II). Inspiratory muscle training (10 weeks) possibly improves maximal inspiratory pressure (RRMS, SPMS, PPMS, EDSS 2-6.5) (1 Class II).

BG-12 (dimethyl fumarate): a review of mechanism of action, efficacy, and safety.

BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory disease, affecting more than 2.5 million people worldwide with more 400,000 cases in the United States alone. There has been considerable improvement in the treatment of MS, with the introduction of disease-modifying drugs; however, new oral therapies may provide additional benefit by providing an alternative treatment modality and the potential for improved adherence by avoiding the injection-associated side effects and anxiety encountered with some first-line agents. BG-12 (dimethyl fumarate) is an oral agent approved in the United States for the treatment of relapsing forms of MS. SCOPE: We review published literature about what is known about the mechanism of action of BG-12, and key efficacy and safety findings from three clinical studies in patients with relapsing-remitting MS (RRMS). FINDINGS: Data from preclinical studies have demonstrated that BG-12 may promote anti-inflammatory and cytoprotective activities that are mediated, at least in part, by the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) antioxidant response pathway. Studies in animals have shown a protective effect of BG-12 on neuronal, axonal and myelin integrity. Results from a phase 2 study and two randomized double-blind placebo-controlled phase 3 studies, CONFIRM and DEFINE, have shown that BG-12 provides clinical and radiologic efficacy in patients with RRMS. At 2 years, BG-12 240 mg twice and three times daily reduced annualized relapse rate (CONFIRM primary endpoint) by 44% and 51% and the risk of relapse (DEFINE primary endpoint) by 49% and 50%, respectively, compared with placebo (all p < 0.001). BG-12 was generally well tolerated and had an acceptable safety profile, with a similar incidence of adverse events across treatment groups. CONCLUSIONS: BG-12 may have cytoprotective and anti-inflammatory properties that contribute to its efficacy among patients with RRMS. Findings from phase 2 and 3 studies further support BG-12 as an effective initial therapy. ClinicalTrials.gov ID: NCT00168701; NCT00420212: NCT00451451.

A personal journey in advocacy.

Over the past decade, neurology advocacy has caught the attention of neurologists feeling increasingly frustrated about the health care environment in which they practice. We describe our experience in practicing advocacy at the national and local levels. Neurologists can participate in many levels of advocacy to benefit their patients and their profession.

Vitamin D and multiple sclerosis.

BACKGROUND: Epidemiological data support a potential relationship between vitamin D deficiency and an increased risk of developing multiple sclerosis (MS). In vitro studies have expanded the potential role of vitamin D and its receptor beyond calcium modulation, regulation, and maintenance of bone mineralization, to include immune modulation. REVIEW SUMMARY: Whether vitamin D immunomodulatory effects can be translated into clinical benefits in MS patients is still a matter of debate. A review of the biochemistry of vitamin D and its synthesized derivatives is discussed in the context of treating vitamin D deficiency. Animal studies, which led to some human studies, are also discussed. Future studies are pending and will likely yield conclusive results as to the benefit and possible synergistic effects of vitamin D with other disease-modifying therapies of MS. CONCLUSIONS: Further prospective studies are needed to identify vitamin D levels during the various phases of MS, including relapses, remissions and progression, and to determine whether correcting vitamin D during any or all of these phases may affect the incidence or even the course of the disease.
