Abstract

Multiple sclerosis (MS) is an autoimmune, inflammatory, demyelinating disease of the central nervous system (CNS), which can occur in many parts of the CNS and result in a wide range of symptoms including sensory impairment, fatigue, walking or balance problems, visual impairment, vertigo and cognitive disabilities. At present, the most commonly used MS treatments are immunomodulating agents, but they have little effect on the disability. Experimental studies show that sodium (Na(+)) accumulation leads to intracellular calcium (Ca(2+)) release, and the increased calcium levels can activate nitric oxide synthase and harmful proteases and lipases. These factors contribute to axonal injury in people with MS. If partial blockade of voltage-gated sodium channels could result in neuroprotection, this would be of benefit for preventing disability progression in these people. Neuroprotection is emerging as a potentially important strategy for preventing disability progression in people with MS. To assess the efficacy and safety of sodium channel blockers for neuroprotection in people with MS to prevent the occurrence of disability and alleviate the burden of the disease. We searched the Cochrane Multiple Sclerosis and Rare Diseases of the Central Nervous System Group Specialised Register (27 August 2015) which, among other sources, contains references from the Cochrane Central Register of Controlled Trials (CENTRAL) (Cochrane Library 2015, Issue (8), MEDLINE (1966 to August 2015), EMBASE (1974 to August 2015), Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1981 to August 2015), Latin American and Caribbean Health Science Information Database (LILACS) (1982 to August 2015), ClinicalTrials.gov (http://clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Portal (ICTRP) search portal (http://apps.who.int/trialsearch). In addition, we searched four Chinese databases, ongoing trials registers and relevant reference lists. Randomised controlled trials (RCTs) that examined sodium channel blockers used alone or as an add-on to any approved treatments for MS. Two review authors independently selected trials, assessed trial quality and extracted the data. Only one study evaluating lamotrigine in secondary progressive MS was eligible. One hundred and twenty people were included, 61 randomly assigned to lamotrigine treatment and 59 to placebo treatment. The average age of participants in the two groups was 51.9 years and 50.1 years, respectively. The proportion of male participants was 27.5%. The period of follow-up was 2 years. No data were found on disability progression and people who experienced relapses. No significant differences were found for serious adverse events between the two groups. Treatment with lamotrigine was associated with more rashes (20% vs 5%, P value 0.03) and transient, dose-related deterioration of mobility (66% vs 34%, P value 0.001) than placebo. Furthermore, no significant difference between the two groups was found in the magnetic resonance imaging (MRI) measurements of cerebral atrophy, Expanded Disability Status Score changes, Multiple Sclerosis Functional Composite score changes. This study was judged to be at high risk of bias. This review will be updated when the three ongoing studies we identified are completed. The quality of evidence was judged to be very low due to the low number of available studies and included participants. There is a lack of evidence to address the review question on the efficacy of sodium channel blockers for people with MS. Assessment of the three ongoing trials might change this conclusion. Further high-quality large scale studies are needed.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 14. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 April 2020.
All research outputs
#2,661,622
of 25,457,858 outputs
Outputs from Cochrane database of systematic reviews
#5,258
of 11,499 outputs
Outputs of similar age
#36,295
of 294,339 outputs
Outputs of similar age from Cochrane database of systematic reviews
#161
of 296 outputs
Altmetric has tracked 25,457,858 research outputs across all sources so far. Compared to these this one has done well and is in the 89th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 11,499 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 40.0. This one has gotten more attention than average, scoring higher than 56% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 294,339 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 296 others from the same source and published within six weeks on either side of this one. This one is in the 45th percentile – i.e., 45% of its contemporaries scored the same or lower than it.
