Magnetic Resonance Imaging (MRI) techniques provided evidences into the understanding of cognitive impairment (CIm) in Multiple Sclerosis (MS).
To investigate the role of white matter (WM) and gray ...matter (GM) in predicting long-term CIm in a cohort of MS patients.
303 out of 597 patients participating in a previous multicenter clinical-MRI study were enrolled (49.4% were lost at follow-up). The following MRI parameters, expressed as fraction (f) of intracranial volume, were evaluated: cerebrospinal fluid (CSF-f), WM-f, GM-f and abnormal WM (AWM-f), a measure of lesion load. Nine years later, cognitive status was assessed in 241 patients using the Symbol Digit Modalities Test (SDMT), the Semantically Related Word List Test (SRWL), the Modified Card Sorting Test (MCST), and the Paced Auditory Serial Addition Test (PASAT). In particular, being SRWL a memory test, both immediate recall and delayed recall were evaluated. MCST scoring was calculated based on the number of categories, number of perseverative and non-perseverative errors.
AWM-f was predictive of an impaired performance 9 years ahead in SDMT (OR 1.49, CI 1.12-1.97 p = 0.006), PASAT (OR 1.43, CI 1.14-1.80 p = 0.002), SRWL-immediate recall (OR 1.72 CI 1.35-2.20 p<0.001), SRWL-delayed recall (OR 1.61 CI 1.28-2.03 p<0.001), MCST-category (OR 1.52, CI 1.2-1.9 p<0.001), MCST-perseverative error(OR 1.51 CI 1.2-1.9 p = 0.001), MCST-non perseverative error (OR 1.26 CI 1.02-1.55 p = 0.032).
In our large MS cohort, focal WM damage appeared to be the most relevant predictor of the long-term cognitive outcome.

Background:
The aim of the study was to evaluate the achievement of ‘no evidence of disease activity’ (NEDA) over a 12-month period in a large multicenter population with relapsing remitting multiple ...sclerosis (RRMS) treated with delayed-release dimethyl fumarate (DMF) and teriflunomide (TRF) using a propensity-score adjustment.
Methods:
A time-to-event method was used to determine the percentages of patients with RRMS (pwRRMS) in both groups achieving NEDA 3 (no relapses, no 12-week confirmed disability progression, and no new T2/gadolinium-enhancing brain lesions). We described the safety profile of the investigated drugs.
Results:
Of the 587 pwRRMS treated with DMF and the 316 pwRRMS treated with TRF, 468 pwRRMS were successfully paired by propensity score: 234 on DMF and 234 on TRF. The percentages of pwRRMS who achieved NEDA 3 were 80.3% in the DMF group and 77.2% in the TRF group. Serious adverse events occurred in four (1.9%) pwRRMS on DMF and in three (1.3%) pwRRMS on TRF.
Conclusions:
DMF and TRF significantly impacted RRMS disease activity in our study. Serious safety concerns were recorded in less than 2% of the studied population.
Diffuse alveolar hemorrhage (DAH) is an acute often life-threatening condition characterized by a variable combination of hemoptysis, dyspnoea, diffuse and bilateral ground glass pulmonary opacities, ...anemia and hypoxemia, that can be induced by different causes, including several drugs. We report here the case of a 25-year-old woman who has been admitted to our pulmonary clinic for the onset of chest pain, cough and haemoptysis, started one week after her first treatment with alemtuzumab for multiple sclerosis. Computed tomography (CT) scan of the chest at the admission showed diffuse and bilateral ground glass pulmonary opacities. Her symptoms resolved completely without any treatment, after the interruption of alemtuzumab, and CT scan of the chest performed one month later showed total disappearance of the pulmonary opacities.
Objective
This study was undertaken to assess the impact of immunosuppressive and immunomodulatory therapies on the severity of coronavirus disease 2019 (COVID‐19) in people with multiple sclerosis ...(PwMS).
Methods
We retrospectively collected data of PwMS with suspected or confirmed COVID‐19. All the patients had complete follow‐up to death or recovery. Severe COVID‐19 was defined by a 3‐level variable: mild disease not requiring hospitalization versus pneumonia or hospitalization versus intensive care unit (ICU) admission or death. We evaluated baseline characteristics and MS therapies associated with severe COVID‐19 by multivariate and propensity score (PS)‐weighted ordinal logistic models. Sensitivity analyses were run to confirm the results.
Results
Of 844 PwMS with suspected (n = 565) or confirmed (n = 279) COVID‐19, 13 (1.54%) died; 11 of them were in a progressive MS phase, and 8 were without any therapy. Thirty‐eight (4.5%) were admitted to an ICU; 99 (11.7%) had radiologically documented pneumonia; 96 (11.4%) were hospitalized.
After adjusting for region, age, sex, progressive MS course, Expanded Disability Status Scale, disease duration, body mass index, comorbidities, and recent methylprednisolone use, therapy with an anti‐CD20 agent (ocrelizumab or rituximab) was significantly associated (odds ratio OR = 2.37, 95% confidence interval CI = 1.18–4.74, p = 0.015) with increased risk of severe COVID‐19. Recent use (<1 month) of methylprednisolone was also associated with a worse outcome (OR = 5.24, 95% CI = 2.20–12.53, p = 0.001). Results were confirmed by the PS‐weighted analysis and by all the sensitivity analyses.
Interpretation
This study showed an acceptable level of safety of therapies with a broad array of mechanisms of action. However, some specific elements of risk emerged. These will need to be considered while the COVID‐19 pandemic persists. ANN NEUROL 2021;89:780–789
•The association of muscle disorders and Multiple Sclerosis is uncommon.•A possible link is the role of immunological factors.•Poliomyelitis may have delayed FSHD1 diagnosis and acting as trigger for ...MS onset.•The co-occurrence of MS has to be kept in mind to avoid diagnostic delays.
We describe herein a “triple trouble” case of a patient affected by Facioscapulohumeral muscular dystrophy type 1 (FSHD1), with a previous history of poliomyelitis, who later developed multiple sclerosis (MS). Association of muscle disorders and MS is uncommon; in fact, there are only three case reports of this unusual co-occurrence. As regard as this combination, some hypotheses have been raised about the role of immunological factors. Genetic basis of FSHD1 is a deletion of a critical number of macrosatellite repeats (D4Z4) in the subtelomeric region of chromosome 4q35, resulting in transcriptional de-repression of a gene DUX4. This molecular change could induce an alteration of immune responses, likely conferring susceptibility to both diseases. In this case, poliomyelitis could have delayed the FSHD1 diagnosis and likely acted as a trigger for MS onset. Association of multiple neurological disorders has to be kept in mind to avoid misinterpretation of symptoms and diagnostic delays.
The COVID-19 outbreak has had a dramatic impact on the healthcare system due to the rapid, worldwide spread of the virus, highlighting several considerations on the best management of infected ...patients and also potential risks and prognostic factors in patients with pre-existing chronic diseases exposed to the virus. Neurodegenerative disorders are known to be chronic, disabling diseases that imply a higher vulnerability to infections, and for this reason, it has been suggested that SARS-CoV-2 infection may have a worse course in these patients. In the present study, we report our experience with 12 patients affected by Parkinson’s disease (PD) who became infected with SARS-Cov-2 due to a COVID-19 outbreak in a care residency, and thus hospitalised in our COVID hospital. Most of the PD patients had a long disease duration and multiple comorbidities even though SARS-CoV-2 manifestations were mild, and none required intensive care. Despite lung conditions, most of our PD patients had mild symptoms: 7 patients were clinically asymptomatic (58.3%); 3 patients had fever, cough, and myalgia (25%) and 2 patients had dyspnoea (16%) that needed high-flow oxygen therapy. Few complications related to PD were seen. All patients were discharged after a mean hospitalisation period of 30 days. Mortality rate during hospitalisation was zero. Our findings suggest that SARS-CoV-2 infection does not have a poor prognosis in patients with PD. More extensive data and evaluations, however, are needed to confirm our data, and caution is warranted.
Background
The introduction of oral disease-modifying therapies (DMTs) for relapsing–remitting multiple sclerosis (RRMS) changed algorithms of RRMS treatment.
Objectives
To compare the effectiveness ...of treatment with dimethyl fumarate (DMF) and teriflunomide (TRF) in a large multicentre Italian cohort of RRMS patients.
Materials and Methods
Patients with RRMS who received treatment with DMF and TRF between January 1st, 2012 and December 31st, 2018 from twelve MS centers were identified. The events investigated were “time-to-first-relapse”, “time-to-Magnetic-Resonance-Imaging (MRI)-activity” and “time-to-disability-progression”.
Results
1445 patients were enrolled (1039 on DMF, 406 on TRF) and followed for a median of 34 months. Patients on TRF were older (43.5 ± 8.6 vs 38.8 ± 9.2 years), with a predominance of men and higher level of disability (
p
< 0.001 for all). Patients on DMF had a higher number of relapses and radiological activity (
p
< .05) at baseline.
Time-varying Cox-model for the event “time-to-first relapse” revealed that no differences were found between the two groups in the first 38 months of treatment (HR
t < 38DMF
= 0.73, CI = 0.52 to 1.03,
p
= 0.079). When the time-on-therapy exceeds 38 months patients on DMF had an approximately 0.3 times lower relapse hazard risk than those who took TRF (HR
t>38DMF
= 3.83, CI = 1.11 to 13.23,
p
= 0.033). Both DMTs controlled similarly MRI activity and disability progression.
Conclusions
Patients on DMF had higher relapse-free survival time than TRF group after the first 38 months on therapy.
Objective
Multiple sclerosis (MS) is a complex disorder in which environmental and genetic factors interact modifying disease risk and course. This multicentre, case–control study involving 18 ...Italian MS Centres investigated MS course by ethnicity and native-country economic status in foreign-born patients living in Italy.
Methods
We identified 457 MS patients who migrated to Italy and 893 age- and sex-matched native-born Italian patients. In our population, 1225 (93.2%) subjects were White Europeans and White Northern Americans (WENA) and 89 (6.8%) patients were from other ethnical groups (OEG); 1109 (82.1%) patients were born in a high-income (HI) Country and 241 (17.9%) in a low-middle-income (LMI) Country. Medical records and patients interviews were used to collect demographic and disease data.
Results
We included 1350 individuals (973 women and 377 men); mean (SD) age was 45.0 (11.7) years. At onset, 25.45% OEG patients vs 12.47% WENA (p = 0.039) had > 3 STIR spine lesions. At recruitment, the same group featured mean (SD) EDSS score of 2.85 (2.23) vs 2.64 (2.28) (p = 0.044) reached in 8.9 (9.0) vs 12.0 (9.0) years (p = 0.018) and underwent 1.10 (4.44) vs. 0.99 (0.40) annual MRI examinations (p = 0.035). At disease onset, patients from LMI countries had higher EDSS score than HI patients (2.40 (1.43) vs 1.99 (1.17); p = 0.032).
Discussion
Our results suggested that both ethnicity and socio-economic status of native country shape MS presentation and course and should be considered for an appropriate management of patients. To the best of our knowledge, this is the first study reporting on the impact of ethnicity in MS at an individual level and beyond an ecological population-perspective.
