Background
The assessment of self-reported outcomes in neuromyelitis optica spectrum disorder (NMOSD) is limited by the lack of validated disease-specific measures. The SymptoMScreen (SyMS) is a ...patient-reported questionnaire for measuring symptom severity in different domains affected by multiple sclerosis (MS), but has not been thoroughly evaluated in NMOSD. The aim of this study was to assess the psychometric properties of the SyMS in a sample of patients with NMOSD.
Methods
A non-interventional, cross-sectional study in adult subjects with NMOSD (Wingerchuk 2015 criteria) was conducted at 13 neuroimmunology clinics applying the SyMS. A non-parametric item response theory procedure, Mokken analysis, was performed to assess the underlying dimensional structure and scalability of items and overall questionnaire. All analyses were performed with R (v4.0.3) using the mokken library.
Results
A total of 70 patients were studied (mean age: 47.5 ± 15 years, 80% female, mean Expanded Disability Status Scale score: 3.0 interquartile range 1.5, 4.5). Symptom severity was low (median SyMS score: 19.0 interquartile range 10.0, 32.0). The SyMS showed a robust internal reliability (Cronbach’s alpha: 0.90 95% confidence interval 0.86, 0.93) and behaved as a unidimensional scale with all items showing scalability coefficients > 0.30. The overall SyMS scalability was 0.45 conforming to a medium scale according to Mokken’s criteria. Fatigue and body pain were the domains with the highest scalability coefficients. The SyMS was associated with disability (rho: 0.586), and physical and psychological quality of life (rho: 0.856 and 0.696, respectively).
Conclusions
The SyMS shows appropriate psychometric characteristics and may constitute a valuable and easy-to-implement option to measure symptom severity in patients with NMOSD.
Introduction
The risk of SARS-CoV-2 infection or severe coronavirus disease 2019 (COVID-19) has been shown to increase in patients with multiple sclerosis (MS). Vaccination is recommended in this ...patient population, and the effect of disease-modifying treatments (DMTs) on response to vaccination should be considered.
Methods
This prospective, observational, cross-sectional study investigated humoral response after COVID-19 vaccination as well as possible predictors for response in patients with MS and other neuroinflammatory diseases who received DMTs in routine clinical practice in Spain. Responses were compared versus those seen in healthy controls.
Results
After vaccination against COVID-19, most patients with MS developed an immune response comparable to that of healthy individuals. However, approximately half of patients receiving a sphingosine-1-phosphate modulator (SP1-M, fingolimod or siponimod) or a B-cell-depleting agent (aCD20, ocrelizumab or rituximab) did not develop protective antibodies, although patients receiving other DMTs had humoral immune responses comparable to healthy controls. Lymphocyte count was not associated with reduced humoral response in patients receiving an SP1-M or aCD20, whereas, in patients receiving an aCD20 or SP1-M, older age was associated with lower anti-SARS-CoV-2 spike protein immunoglobulin G antibody levels.
Conclusions
Treatment with aCD20 or SP1-M therapies appears to be associated with a lower humoral response to vaccines against SARS-CoV-2. Vaccination prior to initiation of these DMTs should be recommended whenever possible.
The objective of this article is to assess the safety of intraspinal infusion of autologous bone marrow mononuclear cells (BMNCs) and, ultimately, to look for histopathological signs of cellular ...neurotrophism in amyotrophic lateral sclerosis (ALS) patients. We conducted an open single arm phase I trial. After 6 months observation, autologous BMNCs were infused into the posterior spinal cord funiculus. Safety was the primary endpoint and was defined as the absence of serious transplant-related adverse events. In addition, forced vital capacity (FVC), ALS-functional rating scale (ALS-FRS), Medical Research Council scale for assessment of muscle power (MRC), and Norris scales were assessed 6 and 3 months prior to the transplant and quarterly afterward for 1 year. Pathological studies were performed in case of death. Eleven patients were included. We did not observe any severe transplant-related adverse event, but there were 43 nonsevere events. Twenty-two (51%) resolved in ≤2 weeks and only four were still present at the end of follow-up. All were common terminology criteria for adverse events grade ≤2. No acceleration in the rate of decline of FVC, ALS-FRS, Norris, or MRC scales was observed. Four patients died on days 359, 378, 808, and 1,058 post-transplant for reasons unrelated to the procedure. Spinal cord pathological analysis showed a greater number of motoneurons in the treated segments compared with the untreated segments (4.2 ± 0.8 motoneurons per section mns per sect and 0.9 ± 0.3 mns per sect, respectively). In the treated segments, motoneurons were surrounded by CD90+ cells and did not show degenerative ubiquitin deposits. This clinical trial confirms not only the safety of intraspinal infusion of autologous BMNC in ALS patients but also provides evidence strongly suggesting their neurotrophic activity.
OBJECTIVE:To (1) determine the value of the recently proposed criteria of neuromyelitis optica (NMO) spectrum disorder (NMOSD) that unify patients with NMO and those with limited forms (NMO/LF) with ...aquaporin-4 immunoglobulin G (AQP4-IgG) antibodies; and (2) investigate the clinical significance of the serologic status in patients with NMO.
METHODS:This was a retrospective, multicenter study of 181 patients fulfilling the 2006 NMO criteria (n = 127) or NMO/LF criteria with AQP4-IgG (n = 54). AQP4-IgG and myelin oligodendrocyte glycoprotein immunoglobulin G (MOG-IgG) antibodies were tested using cell-based assays.
RESULTS:Patients were mainly white (86%) and female (ratio 6.5:1) with median age at onset 39 years (range 10–77). Compared to patients with NMO and AQP4-IgG (n = 94), those with NMO/LF presented more often with longitudinally extensive transverse myelitis (LETM) (p < 0.001), and had lower relapse rates (p = 0.015), but similar disability outcomes. Nonwhite ethnicity and optic neuritis presentation doubled the risk for developing NMO compared with white race (p = 0.008) or LETM presentation (p = 0.008). Nonwhite race (hazard ratio HR 4.3, 95% confidence interval CI 1.4–13.6) and older age at onset were associated with worse outcome (for every 10-year increase, HR 1.7, 95% CI 1.3–2.2). Patients with NMO and MOG-IgG (n = 9) had lower female:male ratio (0.8:1) and better disability outcome than AQP4-IgG-seropositive or double-seronegative patients (p < 0.001).
CONCLUSIONS:In patients with AQP4-IgG, the similar outcomes regardless of the clinical phenotype support the unified term NMOSD; nonwhite ethnicity and older age at onset are associated with worse outcome. Double-seronegative and AQP4-IgG-seropositive NMO have a similar clinical outcome. The better prognosis of patients with MOG-IgG and NMO suggests that phenotypic and serologic classification is useful.
Patient-reported outcomes (PROs) provide clinicians with further understanding of the impact of treatment on patients’ daily lives. In addition, real-world studies, which employ broader inclusion ...criteria than randomized trials, may help to inform prescribing decisions when selecting a disease-modifying therapy (DMT) to treat relapsing forms of MS (RMS). We sought to use PROs to determine patient treatment satisfaction and other treatment outcomes, and report safety and tolerability associated with teriflunomide, in the global, phase 4 Teri-PRO study (NCT01895335).
Patients with RMS (N = 1000) received teriflunomide for 48 weeks per local labeling. The primary endpoint was Global Satisfaction with teriflunomide treatment measured by the Treatment Satisfaction Questionnaire for Medication (TSQM, V1.4). Secondary endpoints included TSQM scores at Week (W)48 vs baseline in patients switching to teriflunomide from other DMTs (‘switchers’), additional PROs, and safety.
Mean TSQM Global Satisfaction score at W48 was high (68.2). Switchers reported significant improvements across all four TSQM domains at W48 vs baseline (all p < 0.0001). Adverse events were consistent with teriflunomide clinical trials.
Patients reported high treatment satisfaction with teriflunomide, with switchers also reporting improved treatment satisfaction vs baseline. High treatment satisfaction in patients with RMS may lead to improved adherence, and hence treatment outcomes.
•Teri-PRO evaluated treatment satisfaction in RMS patients receiving teriflunomide.•Patients reported high levels of satisfaction across all 4 domains of the TSQM.•Patients who switched from a prior DMT reported improved treatment satisfaction.•Quality of life, and physician- and patient-reported disability, remained stable.•Safety and tolerability were consistent with teriflunomide clinical trial program.
The assessment of self-reported outcomes in neuromyelitis optica spectrum disorder (NMOSD) is limited by the lack of validated disease-specific measures. The SymptoMScreen (SyMS) is a ...patient-reported questionnaire for measuring symptom severity in different domains affected by multiple sclerosis (MS), but has not been thoroughly evaluated in NMOSD.

The overall SyMS scalability was 0.45 conforming to a medium scale according to Mokken's criteria. Fatigue and body pain were the domains with the highest scalability coefficients. The SyMS was associated with disability (rho: 0.586), and physical and psychological quality of life (rho: 0.856 and 0.696, respectively). The SyMS shows appropriate psychometric characteristics and may constitute a valuable and easy-to-implement option to measure symptom severity in patients with NMOSD.
•Teri-PRO patients who switched DMT reported high levels of treatment satisfaction.•This was observed regardless of reason for treating with teriflunomide.•Patients also showed stability in ...disability and cognition over the study period.•The annualized treated relapse rate was low over the study period.•Safety and tolerability profile was consistent with teriflunomide clinical trials.
Patient-reported outcomes (PROs) can assist clinicians in understanding the impact of disease-modifying therapy (DMT) on the daily lives of patients with multiple sclerosis (MS). With an increased number of DMTs becoming available, patients are now switching treatments more frequently in clinical practice. The effects of switching DMTs on a patient's daily life and their disease course may be reflected in PROs. The global, multicenter, open-label, phase 4 Teri-PRO study (NCT01895335), which was conducted in routine clinical practice, previously showed statistically and clinically significant increases in patient-reported treatment satisfaction in patients switching to teriflunomide from other DMTs. The impact of switching to teriflunomide from other DMTs on treatment satisfaction and a range of additional PROs was also evaluated.
Patients with relapsing forms of MS (N = 1000) received teriflunomide for 48 weeks per local labeling. Outcomes assessed in this analysis included treatment satisfaction (as measured by Treatment Satisfaction Questionnaire for Medication Version 1.4), disability worsening (as measured using the Expanded Disability Status Scale EDSS score, the Patient-Determined Disease Steps scale, and the Multiple Sclerosis Performance Scale), cognition (as measured using the Symbol Digit Modalities Test SDMT), treated relapses, quality of life (as measured by the Multiple Sclerosis International Quality of Life MusiQoL questionnaire and the Stern Leisure Activity Scale), and safety/tolerability over the course of the study in the subgroup of patients switching to teriflunomide from another DMT (n = 594).
Patients reported significant improvements in treatment satisfaction scores following the switch to teriflunomide regardless of the reason for treating with teriflunomide (Global Satisfaction, disease worsening: baseline, 46.0, Week 48, 65.1; convenience: baseline, 57.4, Week 48, 72.4; intolerance: baseline, 50.9, Week 48, 71.1; side effects: baseline, 49.7, Week 48, 67.2; P < 0.0001 in all comparisons). These patients also showed improvement or stability in PROs evaluating disability worsening, cognition, and quality of life (EDSS: baseline, 3.1, Week 48, 3.0; SDMT: baseline, 0.975, Week 48, 0.978; MusiQoL: baseline, 67.5, Week 48, 69.5). The safety and tolerability profile of teriflunomide was consistent with that observed in other teriflunomide clinical trials.
This analysis of the Teri-PRO study demonstrates the value of switching to teriflunomide from other DMTs in a real-world, clinical practice setting. The high levels of treatment satisfaction associated with teriflunomide in Teri-PRO may lead to improved adherence and thus improved outcomes.

OBJECTIVETo understand COVID-19 characteristics in people with multiple sclerosis (MS) and identify high-risk individuals due to their immunocompromised state resulting from the use of ...disease-modifying treatments. METHODSRetrospective and multicenter registry in patients with MS with suspected or confirmed COVID-19 diagnosis and available disease course (mild = ambulatory; severe = hospitalization; and critical = intensive care unit/death). Cases were analyzed for associations between MS characteristics and COVID-19 course and for identifying risk factors for a fatal outcome. RESULTSOf the 326 patients analyzed, 120 were cases confirmed by real-time PCR, 34 by a serologic test, and 205 were suspected. Sixty-nine patients (21.3%) developed severe infection, 10 (3%) critical, and 7 (2.1%) died. Ambulatory patients were higher in relapsing MS forms, treated with injectables and oral first-line agents, whereas more severe cases were observed in patients on pulsed immunosuppressors and critical cases among patients with no therapy. Severe and critical infections were more likely to affect older males with comorbidities, with progressive MS forms, a longer disease course, and higher disability. Fifteen of 33 patients treated with rituximab were hospitalized. Four deceased patients have progressive MS, 5 were not receiving MS therapy, and 2 were treated (natalizumab and rituximab). Multivariate analysis showed age (OR 1.09, 95% CI, 1.04-1.17) as the only independent risk factor for a fatal outcome. CONCLUSIONSThis study has not demonstrated the presumed critical role of MS therapy in the course of COVID-19 but evidenced that people with MS with advanced age and disease, in progressive course, and those who are more disabled have a higher probability of severe and even fatal disease.
Introduction
Neuromyelitis optica spectrum disorder (NMOSD) is associated with a reduced health-related quality of life (HRQoL). The purpose of this study was to describe the impact of NMOSD on HRQoL ...from the patients’ perspective and its relationship with other disease factors.
Methods
An observational, cross-sectional study was conducted at 13 neuroimmunology clinics in Spain. Patients with NMOSD diagnosis (2015 Wingerchuk criteria) were included. The 29-item Multiple Sclerosis Impact Scale (MSIS-29) was used to assess the HRQoL. Different questionnaires were used to measure symptom severity, stigma, mood disorders, pain, fatigue, and difficulties in the workplace. Factors that impact HRQoL were identified by Spearman’s correlation and multivariate linear regression analysis.
Results
Seventy-one patients were included (mean age 47.4 ± 14.9 years, 80.3% female, mean time since disease onset 9.9 ± 8.1 years). The median Expanded Disability Status Scale score was 3.0 (1.5–4.5). The mean (± SD) physical and psychological MSIS-29 sub-scores were 41.9 ± 16.8 and 20.9 ± 8.3, respectively. Fatigue and body pain were the most prevalent symptoms. Depressive symptoms were found in 44.3% (
n
= 31) of patients. The physical MSIS-29 dimension showed the highest correlation with symptom severity (
ρ
= 0.85584,
p
< 0.0001), whereas the highest correlations for psychological MSIS-29 dimension were pain, MSIS-29 physical dimension, and depression (
ρ
= 0.76487, 0.72779, 0.71380;
p
< 0.0001, respectively). Pain was a predictor of both dimensions of MSIS-29.
Conclusion
Fatigue, pain, and depressive symptoms are frequent problems among patients with NMOSD, impacting on their quality of life. Assessment of patient-oriented outcomes may be useful to achieve a holistic approach, allowing early specific interventions.
