Multiple Sclerosis and related Disorders

BACKGROUND: Little is known about the quality of life (QOL) of patients with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). We compared QOL and associated factors in patients with MOGAD and aquaporin4 IgG (AQP4-IgG) positive neuromyelitis optica spectrum disorder (NMOSD). METHODS: This multicenter questionnaire study compared the QOL of 41 patients with MOGAD and 78 with AQP4-IgG positive NMOSD. Patients who were positive for AQP4-IgG or MOG antibodies were included...

BACKGROUND: Relapsing-remitting multiple sclerosis (RRMS) is a most common form of multiple sclerosis in which periods of neurological worsening are followed by periods of clinical remission. RRMS relapses are caused by an acute autoimmune inflammatory process, which can occur in any area of the central nervous system. Although development of exacerbation cannot yet be accurately predicted, various external factors are known to affect its risk. These factors may trigger the pathological process through epigenetic mechanisms of gene expression regulation, first of all, through changes in DNA methylation...

INTRODUCTION: Ocrelizumab (OCR) is a highly effective treatment of multiple sclerosis (MS), and B cell repopulation profiles suggest that it might be used as an immune reconstitution therapy. However, data on disease recurrence after stopping treatment with OCR are scarce. Our objective was to evaluate the recurrence of disease activity after OCR discontinuation. METHODS: In this multicenter retrospective cohort study, we included MS patients who discontinued OCR, without switching to another treatment, for twelve months or more, after having received at least one full dosage of 600 mg...

BACKGROUND: People with multiple sclerosis (pwMS) face disease-related stress throughout their lives, often resulting in depressive mood and fear of progression (FoP). People with a pronounced sense of humor demonstrate greater resilience to stress and tend to perceive threats as challenges. This research investigates whether humor can be identified as a relevant coping factor in pwMS regarding depressive mood and FoP. METHODS: Participants were 77 German inpatients aged 25-64 years with predominantly relapsing-remitting MS...

BACKGROUND: The European Cross-Cultural Neuropsychological Test Battery (CNTB) has been proposed as a comprehensive battery for cognitive assessment, reducing the potential impact of cultural variables. In this validation study, we aimed to evaluate the diagnostic capacity of CNTB for the assessment of participants with multiple sclerosis (pwMS) compared to the Neuronorma battery (NN) according to the International Classification of Cognitive Disorders in MS criteria, and to develop machine learning (ML) algorithms to improve the diagnostic capacity of CNTB and to select the most relevant tests...

BACKGROUND: Distance walking fatigability (DWF) in people with multiple sclerosis (pwMS) is defined as a decrease in the distance walking over time. However, declines in gait quality (i.e., gait quality fatigability- GQF) may occur independently or alongside DWF. OBJECTIVE: i) to investigate how walking fatigability manifests and its prevalence in pwMS; ii) to describe the temporal pattern of the changes of specific gait characteristics during the 6-minute walking test (6MWT) METHODS: Eighty-eight pwMS (EDSS 4[0-6...

BACKGROUND: Alexithymia refers to difficulty identifying (DIF) and describing (DDF) feelings and externally oriented thinking (EOT). Its prevalence remains unknown in the radiologically isolated syndrome (RIS), the preclinical multiple sclerosis (MS) phase. METHODS: Alexithymia was measured with the Toronto Alexithymia Scale (TAS-20) in 29 RIS and age and gender-matched healthy controls and relapsing-remitting (RR) MS with an EDSS <3. All participants completed evaluations of cognition (BCCOG-SEP), depression (Fast-BDI), fatigue (EMIF), and quality of life (SEP-59)...

BACKGROUND: Vascular comorbidities are prevalent in persons with multiple sclerosis (MS), yet less is known about underlying vascular function (VF). We performed a systematic review with meta-analysis of studies that compared VF in persons with MS and healthy controls and examined factors that may moderate the difference in vascular outcomes between groups. METHODS: We conducted a systematic search using PubMed/MEDLINE, CINAHL, and Embase from inception through March 2024...

Depression affects around 50% of people with Multiple Sclerosis (pwMS) during their lifetime. PwMS are typically less physically active and spend twice as much time engaging in sedentary behaviour compared to the general population. Therefore, a better understanding of the factors associated with depression in pwMS, as well as the relationship between depression and sedentary behaviour and physical activity, is crucial for developing effective therapeutic strategies MS treatment. This study aimed to investigate whether the presence of depressive symptoms in pwMS is related to a longer duration of sedentary behaviour...

BACKGROUND: Multiple Sclerosis (MS) course was shown to be more severe among North Africans compared to Caucasians. Validation of prognostic biomarkers of disease activity and severity is a priority in our practice. OBJECTIVE: We aimed to investigate the association between baseline cerebrospinal fluid (CSF) and serum NfL (sNFL) levels and disease activity and disability accrual in a cohort of Tunisian patients with MS. METHODS: A cross-sectional study was conducted, in the department of Neurology of Razi Hospital, including patients diagnosed with MS...

BACKGROUND: With multiple treatment options, choosing the initial disease-modifying agent (DMA) could be crucial to managing multiple sclerosis (MS). Common treatment strategies recommend starting patients with moderate-efficacy disease-modifying agents (meDMAs), while others advocate initiating high-efficacy disease-modifying agents (heDMAs). However, limited real-world evidence exists regarding the factors associated with utilizing differing treatment strategies in the MS. OBJECTIVE: This study evaluated the factors associated with the initiation of heDMAs in comparison to meDMAs among patients with MS...

No study has investigated the length of time it takes to diagnose multiple sclerosis (MS) or neuromyelitis optic spectrum disorder (NMOSD, aquaporin 4 antibody disease or myelin oligodendrocyte glycoprotein antibody disease, MOGAD) following the onset of de novo optic neuritis (ON). Minimizing the time between ON and downstream diagnoses needs urgency since early diagnosis equals early treatment. The time elapsed from ON to a subsequent diagnosis of MS/NMOSD was estimated through analysis of retrospective data collected from the Axon Registry (AR) of the American Academy of Neurology (AAN) and from the University of Kentucky (UK), Lexington...

BACKGROUND: Lifestyle changes have been demonstrated to impact pathophysiology in Multiple Sclerosis (MS). Various diet and exercise protocols have been reported to improve symptoms and function in persons with MS. Evidence is accumulating that interventions as early as possible in the disease course are warranted. The objective of this study was to investigate the effect of a remotely delivered lifestyle program focusing on specific diet and exercise recommendations in persons with early MS...

We investigated if differentially expressed mRNA targets could be used as surrogate markers for circulating B cells and subsets. In paired blood samples from patients with untreated, anti-CD20-treated, fingolimod-treated, and natalizumab-treated multiple sclerosis, whole blood expression of CD19 correlated with B cell counts determined by flow cytometry, ROR1 with transitional B cells, TCL1A and ZNF727 with naïve B cells, NEXMIF with memory B cells and BCMA with plasmablasts. CD19 expression distinguished patients with B cell repletion and may be used as an alternative to flow cytometry, but NEXMIF was unsuitable for memory B cell monitoring in rituximab-treated patients...

PURPOSE: The retinal microvascular network plays a crucial role in inflammatory injury in paediatric optic neuritis (PON) with serum MOG antibody positivity (MOG + PON). This study compared retinal microvascular densities and structural alterations in MOG + PON eyes with paediatric isolated optic neuritis (PION) eyes and followed up with the final best-corrected visual acuity (BCVA) after 6 months. METHODS: A total of 29 children (52 eyes) with PON, including 15 MOG + PON cases (28 eyes), 6 PION cases (10 eyes), 2 neuromyelitis optica spectrum disorders associated PON(NMOSD-PON) cases (4 eyes), 6 MOG-associated disease (MOGAD) patients without ON-affected eyes (MOG + NPON) cases (10 eyes) and age- and gender-matched healthy controls (HCs) underwent superficial/deep retinal angiography density (SAD/DAD) by optical coherence tomography angiography (OCTA)...

INTRODUCTION: Neurogenic lower urinary tract (NLUTD), bowel (NBD), and sexual dysfunction (SD) are commonly observed in patients with (pw) multiple sclerosis (MS) and diminish the patients' quality of life (QoL). This systematic review aim to evaluate and discuss the current algorithms for the management of these issues. METHODS: A systematic review was conducted on the PubMed in June 2024. The primary search criterion was the presence of the term 'algorithm/s' or 'management/ing' in the title and/or abstract, followed by the MeSH term 'multiple sclerosis' and a combination of free-text keywords referring to NLUTD, NBD or SD...

BACKGROUND: The humanized monoclonal anti-CD20-antibody ofatumumab is highly effective in treating relapsing multiple sclerosis (MS). OBJECTIVE: This study aimed to investigate the immanent effect of ofatumumab on the peripheral immune system, particularly targeting B and T cells expressing CD20. METHODS: Blood samples of 53 MS patients receiving ofatumumab were collected prior to first application and after one week, two weeks and three months...

In recent years, there has been a growing interest in exploring the non-classical symptoms of multiple sclerosis (MS), with a particular focus on cognitive impairments associated with the disease's progression. These cognitive symptoms are now recognized as crucial elements in the assessment of disease activity. In this context, neurophysiology has emerged as a valuable and accessible tool for studying and addressing cognitive decline in individuals with MS. This scoping literature review investigates the role of neurophysiology in assessing and treating cognitive impairment in MS patients...
