Abstract Backgrounds: Multiple Sclerosis (MS) is a chronic inflammatory and autoimmune disease linked to several inflammatory and dietary parameters. This study was carried out to determine the relationship between serum leptin, orexin-A, and TGF-β levels with BMI in MS patients.Methods and results: In this cross-sectional study, 25 relapsing-remitting multiple sclerosis (RRMS) patients and 40 healthy controls were enrolled. The serum level of Leptin, Orexin-A, and TGF- were measured by the Enzyme-linked immunosorbent assay (ELISA). The data was analyzed using descriptive statistics, t-test, Chi-square test, and Linear regression test. A total of 65 volunteers, including 25 MS patients and 40 healthy, were enrolled in the study. The mean age of individuals in the case and control groups was 38.04 ± 7.53 and 40.23 ± 5.88. There were no statistically significant differences between the case and control groups regarding gender, age, alcohol, and cigarette use (P>0.05). The mean serum levels of Orexin-A and TGF-ß were lower among multiple sclerosis patients than in healthy controls, but leptin was higher (42.8 vs. 18.9 ng/ml, P<0.001). The relationship between BMI and serum levels of Orexin-A, TGF-ß, and Leptin among Multiple Sclerosis patients was not statistically significant (P > 0.05).Conclusion: Our results showed that the serum levels of Orexin-A and TGF-β were significantly lower. The serum level of leptin was higher among multiple sclerosis patients than among healthy controls. Also, there was no statistically significant relationship between BMI and serum levels of Orexin-A, TGF-ß, and Leptin among multiple sclerosis patients.

Abstract Objective To review instruments used to assess disease stability or progression in persons with multiple sclerosis (pwMS) that can guide clinicians in optimizing therapy. Methods A non-systematic review of scientific literature was undertaken to explore modalities of monitoring symptoms and the disease evolution of MS. Results Multiple outcome measures, or tools, have been developed for use in MS research as well as for the clinical management of pwMS. Beginning with the Expanded Disability Status Scale, introduced in 1983, clinicians and researchers have developed monitoring modalities to assess all aspects of MS and the neurological impairment it causes. Conclusions Much progress has been made in recent decades for the management of MS and for the evaluation of disease progression. New technology, such as wearable sensors, will provide new opportunities to better understand changes in function, dexterity, and cognition. Essential work over the decades since EDSS was introduced continues to improve our ability to treat this debilitating disease.

BackgroundSARS-CoV-2 seroconversion rate after COVID-19 may be influenced by disease-modifying therapies (DMTs) in patients with multiple sclerosis (MS) or neuromyelitis optica spectrum disorders (NMO-SD).ObjectiveTo investigate the seroprevalence and the quantity of SARS-CoV-2 antibodies in a cohort of patients with MS or NMO-SD.MethodsBlood samples were collected in patients diagnosed with COVID-19 between 19 February 2020 and 26 February 2021. SARS-CoV-2 antibody positivity rates and Ig levels (anti-S IgG titre, anti-S IgA index, anti-N IgG index) were compared between DMTs groups. Multivariate logistic and linear regression models were used to estimate the influence of DMTs and other confounding variables on SARS-CoV-2 serological outcomes.Results119 patients (115 MS, 4 NMO, mean age: 43.0 years) were analysed. Overall, seroconversion rate was 80.6% within 5.0 (SD 3.4) months after infection. 20/21 (95.2%) patients without DMT and 66/77 (85.7%) patients on DMTs other than anti-CD20 had at least one SARS-CoV-2 Ig positivity, while this rate decreased to only 10/21 (47.6%) for patients on anti-CD20 (p<0.001). Being on anti-CD20 was associated with a decreased odd of positive serology (OR, 0.07 (95% CI 0.01 to 0.69), p=0.02) independently from time to COVID-19, total IgG level, age, sex and COVID-19 severity. Time between last anti-CD20 infusion and COVID-19 was longer (mean (SD), 3.7 (2.0) months) in seropositive patients compared with seronegative patients (mean (SD), 1.9 (1.5) months, p=0.04).ConclusionsSARS-CoV-2 antibody response was decreased in patients with MS or NMO-SD treated with anti-CD20 therapies. Monitoring long-term risk of reinfection and specific vaccination strategies in this population may be warranted.Trial registration numberNCT04568707.

Background: The kinetics of B cell repopulation in MS patients treated with Ocrelizumab is highly variable, suggesting that a fixed dosage and time scheduling might be not optimal. We aimed to investigate whether B cell repopulation kinetics influences clinical and radiological outcomes and whether circulating immune asset at baseline affects B cell repopulation kinetics. Methods: 218 MS patients treated with Ocrelizumab were included. Every six months we collected data on clinical and magnetic resonance imaging (MRI) activity and lymphocyte subsets at baseline. According to B cell counts at six and twelve months, we identified two groups of patients, those with fast repopulation rate (FR) and those with slow repopulation rate (SR). Results: A significant reduction in clinical and radiological activity was found. One hundred fifty-five patients had complete data and received at least three treatment cycles (twelve-month follow-up). After six months, the FR patients were 41/155 (26.45%) and 10/41 (29.27%) remained non-depleted after twelve months. FR patients showed a significantly higher percentage of active MRI scan at twelve months (17.39% vs. 2.53%; p = 0,008). Furthermore, FR patients had a higher baseline B cell count compared to patients with an SR (p = 0.02 and p = 0.002, at the six- and twelve-month follow-ups, respectively). Conclusion: A considerable proportion of MS patients did not achieve a complete CD19 cell depletion and these patients had a higher baseline CD19 cell count. These findings, together with the higher MRI activity found in FR patients, suggest that the Ocrelizumab dosage could be tailored depending on CD19 cell counts at baseline in order to achieve complete disease control in all patients.

Abstract Background: Multiple sclerosis (MS) detrimentally affects cognition and quality of life (QOL). Interventions that can improve cognitive deficit and QOL in people with MS are desired. This pilot study investigated the possible effects of vibration training on improving cognition and QOL in people with MS. Methods: Eighteen adults with MS were randomized into two groups: training and control. The training group underwent 6 weeks of vibration training, and the control group maintained their normal lifestyle throughout the study. In both groups, before and after the training course, the disability status was evaluated by the Patient-Determined Disease Steps scale and the Multiple Sclerosis Functional Composite (MSFC), cognitive function was assessed by the Behavior Rating Inventory of Executive Function (BRIEF) and the Selective Reminding Test (SRT), and QOL was gauged by the 36-item Short Form Health Survey (SF-36). Results: The training was well accepted by the participants, and no major adverse event was reported. All participants finished the entire protocol. Compared with the control group, after the training the training group showed greater improvements in MSFC score, Metacognition Index score of the BRIEF, SRT score, and physical domain score of the SF-36. Conclusions: These results suggest that vibration training could be an effective alternative training paradigm to enhance cognition and QOL in people with MS, and they provide an encouraging base to conduct a large-scale clinical trial.
