Background: Pain is a frequent symptom in aquaporin-4-immunoglobulin-G-positive neuromyelitis optica spectrum disorders (AQP4-IgG-pos. NMOSD). Data on pain in myelin-oligodendrocyte-glycoprotein-immunoglobulin-G autoimmunity with a clinical NMOSD phenotype (MOG-IgG-pos. NMOSD) are scarce. Objective: The objective of this paper is to investigate pain in MOG-IgG-pos. NMOSD, AQP4-IgG-pos. NMOSD and NMOSD without AQP4/MOG-IgG detection (AQP4/MOG-IgG-neg. NMOSD). Methods: Forty-nine MOG-IgG-pos...

Motor dysfunction, particularly ataxia, is one of the predominant clinical manifestations in patients with multiple sclerosis (MS). Assessment of motor dysfunction suffers from a high variability. We investigated whether the clinical rating of ataxia can be improved through the use of reference videos, covering the spectrum of severity degrees as defined in the Neurostatus-Expanded Disability Status Scale. Twenty-five neurologists participated. The variability of their assessments was significantly lower when reference videos were used (SD = 0...

Background/Objective: Novel biomarkers identifying and predicting disease activity in multiple sclerosis (MS) would be valuable for primary diagnosis and as outcome measures for monitoring therapeutic effects in clinical trials. Axonal loss is present from the earliest stages of MS and correlates with disability measures. Growth-associated protein 43 (GAP-43) is a presynaptic protein with induced expression during axonal growth. We hypothesized this protein could serve as a biomarker of axonal regeneration capacity in MS...

There is an obvious disconnect between evidence of benefits and rates of participation in exercise and physical activity among people living with multiple sclerosis (MS). We propose that the problem with exercise behavior in MS (i.e. lack of broad or increasing participation by people with MS despite evidence of meaningful benefits) might be ameliorated through the inclusion of behavior change theory in the design of exercise programs and promotion efforts, as has been undertaken in other populations such as breast cancer survivors...

Background: Population-based estimates of costs of illness and health-related quality of life, by disability levels among people with multiple sclerosis, are lacking. Objectives: To estimate the annual costs of illness and health-related quality of life, by disability levels, among multiple sclerosis patients, 21-64 years of age. Methods: Microdata from Swedish nationwide registers were linked to estimate the prevalence-based costs of illness in 2013, including direct costs (prescription drug use and specialised healthcare) and indirect costs (calculated using sick leave and disability pension), and health-related quality of life (estimated from the EQ-5D)...

We performed a cross-sectional study in 123 Chinese multiple sclerosis patients residing in Hong Kong to evaluate their anti-John Cunningham virus status using STRATIFY JCV DxSelect assays. Anti-John Cunningham virus antibody was present in 98/123 (80%) subjects, among which 75/98 (77%) had an anti-John Cunningham virus index ≥1.5. Anti-John Cunningham virus antibody seropositivity was not correlated with age, disease duration, Expanded Disability Status Scale scores, types of multiple sclerosis (relapsing vs progressive), or disease-modifying treatments used...

Background: A considerable number of people with multiple sclerosis (pwMS) live in low- and middle-income countries (LMIC), where lack of resource adversely affects access to effective disease-modifying treatment. Objective: The objective of this commentary is to propose a useful cost-effective disease-modifying treatment option for pwMS in LMIC with potential high efficacy and high convenience to the pwMS and treating physician. Viewpoint : We propose using generic 2-chloro-2'-deoxyadenosine (cladribine), a small molecule licensed for treatment of people with hairy cell leukaemia, as a solution of this significant equity imbalance...

Background and objective: The 12-item Multiple Sclerosis Walking Scale (MSWS-12) is a patient-reported outcome instrument that quantifies the progressive loss of walking ability from the patient perspective. However, previous psychometric analyses indicated floor and ceiling effects across the multiple sclerosis severity spectrum. This study aimed to address floor effects by creating a gait module that can be used in conjunction with the MSWS-12 for better measurement of treatment benefit in the higher functioning multiple sclerosis population...

Background: Disease-modifying therapies are thought to reduce the conversion rate to secondary progressive multiple sclerosis. Objective: To explore the rate, chronology, and contributing factors of conversion to the progressive phase in treated relapsing-remitting multiple sclerosis patients. Methods: Our study included 204 patients treated for relapsing-remitting multiple sclerosis between 1995 and 2002, prospectively followed to date. Kaplan-Meier analysis was applied to estimate the time until secondary progressive multiple sclerosis conversion, and multivariate survival analysis with a Cox regression model was used to analyse prognostic factors...

Purpose: Sexual dysfunction is a common but often overlooked secondary symptom of multiple sclerosis (MS) and can be associated with a decreased health-related quality of life (HRQoL). Natalizumab is a disease-modifying therapy approved for the treatment of relapsing forms of MS. In addition to its efficacy, those using natalizumab have shown improvement in HRQoL parameters, including fatigue and cognition. The idea that improvement in fatigue may also correlate with improvement in sexual dysfunction is the impetus for this study...

Background: Although cognitive dysfunction is a leading cause of disability and poor quality of life in patients with multiple sclerosis (MS), it is infrequently tested in routine clinical evaluation. Development of a cognitive testing paradigm that captured MS-related cognitive dysfunction and could be obtained in a routine clinical setting may increase surveillance and recognition of cognitive dysfunction. Objectives: This was a pilot study to determine if Cognivue could find cognitive performance differences between patients with MS and healthy controls (HC)...

Patients enrolled in the phase 3 TOWER study (NCT00751881) of teriflunomide had variable treatment durations (48-173 weeks). This has led to challenges when interpreting results in the context of other phase 3 trials of disease-modifying therapies for multiple sclerosis, which typically have a fixed 2-year duration. This communication reports clinical outcomes in TOWER over a fixed 2-year period. Reductions in annualised relapse rates and 12-week confirmed disability worsening associated with teriflunomide were comparable between overall intent-to-treat and fixed 2-year study populations in TOWER...
