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
In childhood and juvenile cases, multiple sclerosis (MS) is associated with cognitive impairment and low IQ scores, the latter related to younger age at onset. These aspects are of critical importance in helping children and adolescents with MS to manage their difficulties and psychosocial challenges.
The Brief Repeatable Battery of Neuropsychological Tests (BRB) is by far the most widely used instrument to estimate cognitive dysfunction in multiple sclerosis (MS) patients. However, the paucity of normative data currently limits its applicability. We administered the BRB to 200 healthy subjects to obtain normative values. Moreover, we assessed the influence of demographic factors on the test scores and calculated corrections for these relevant factors. To test executive functions not explored by the BRB, we also included the Stroop word-color task (ST). Higher educational level was associated with better performance on all the tests, except for the world list generation (WLG) and the ST, considering version A, and on Symbol Digit Modalities Test (SDMT), Paced Auditory Serial Addition Test (PASAT) and Selective Reminding Test-Delayed (SRT-D), considering version B. Females performed better than males on the WLG considering version A, and on the SRT-Long-Term Storage (SRT-LTS) and SRT-Consistent Long-Term Retrieval (SRT-CLTR) considering version B. Increasing age was associated with worse performance on the ST in version A, and on the SRT-LTS, SRT-CLTR and WLG in version B. Our data can improve the applicability of the BRB for both clinical and research purposes.

In a multicenter cross-sectional study, the authors assessed pain in patients with multiple sclerosis (MS) using a symptom-oriented approach. Out of 2,077 questionnaires, we used 1,672 for data analysis. Pain and frequencies included trigeminal neuralgia 2%, Lhermitte's sign 9%, dysesthetic pain 18.1%, back pain 16.4%, and painful tonic spasms 11%. Comparison between different groups showed significant differences for age, Expanded Disability Status Scale, disease duration, and disease course, but not for sex. This study underlines the relevance of pain in the clinical history of MS.
Poor treatment adherence is problematic in many therapy areas, including multiple sclerosis (MS). Several immunomodulatory drugs are available for the treatment of MS, all of which require frequent parenteral administration. Current first-line therapies are two formulations of interferon (IFN) beta-1a, one of IFN beta-1b, and one of glatiramer acetate. Discontinuation of treatment is common, particularly in the first few months after initiation. Although the true effect of poor adherence to MS therapy is not known, it is likely to lead to a fall in treatment efficacy. Many factors influence a patient’s adherence to treatment, including the patient’s MS subtype and disability level, cognitive impairment resulting from MS, perceived lack of efficacy of the prescribed medication, and adverse events associated with MS therapy. This article summarizes the barriers to adherence to MS therapies, and discusses patient management strategies that can be employed to encourage adherence. Future advances in the field of MS treatment will be explored, including the development of orally administered drugs, which may enhance adherence.
Cognitive impairment occurs in approximately one-fifth of mildly disabled patients with MS and is associated with specific MRI disease measures. Assessment of cognitive function at diagnosis could facilitate the identification of patients who may benefit from therapeutic intervention with disease-modifying therapies to prevent further lesion development.
It is only through further studies that it will be possible to identify patients with, or at risk of, cognitive impairment and to provide appropriate therapy to limit the effects of this potentially devastating symptom.
