Immune thrombocytopenia in alemtuzumab-treated MS patients: Incidence, detection, and management.

Alemtuzumab is a highly effective therapy for relapsing-remitting multiple sclerosis (RRMS), and immune thrombocytopenia (ITP) has been identified as a risk.


Accumulation of TDP-43 in the cytoplasm of diseased neurons is the pathological hallmark of Frontotemporal Dementia-TDP (FTLD-TDP) and Amyotrophic Lateral Sclerosis (ALS), two diseases that lack of efficacious medicine to prevent or to stop disease progression. The discovery that mutations in the TARDBP gene (coding for the nuclear protein known as TDP-43) in both FTLD and ALS patients provided ev...

Identification and Preclinical Pharmacology of ((1R,3S)-1-amino-3-((S)-6-(2-methoxyphenethyl)-5,6,7,8-tetrahydronaphthalen-2-yl)cyclopentyl)methanol (BMS-986166): A Differentiated Sphingosine-1-Phosphate (S1P1) Receptor Modulator Advanced into Clinical Trials.

Recently, our research group reported the identification of BMS-986104 (2) as a differentiated S1P1 receptor modulator. In comparison to fingolimod (FTY720, 1), a full agonist of S1P1 currently marketed for the treatment of relapse remitting multiple sclerosis (RRMS), 2 offers several potential advantages having demonstrated improved safety multiples in pre-clinical evaluations against undesired p...

Smoking and Amyotrophic Lateral Sclerosis: A Mendelian Randomization Study.

In this study, we examined the potential causal effect of smoking on amyotrophic lateral sclerosis using the Project MinE data involving 12,577 patients with amyotrophic lateral sclerosis and 23,475 controls in a Mendelian randomization (MR) framework. The MR approach has the potential to investigate causal relationship between a risk factor and a disease, avoiding confounding and information bias...

Isolated recurrent myelitis in a persistent MOG positive patient.

MOG-Ab positive CNS demyelination typically involves the optic nerve and spinal cord. Recurrent episodes of myelitis without optic neuritis are very rare and according to current literature review represent about 3-5% of positive MOG-Ab cases. We report a 30-year-old woman with positive serum MOG-Ab suffering two discrete episodes of transverse myelitis without ophthalmic involvement. Repeated ser...

Brain Aging and Gut⁻Brain Axis.

In the last decade, the microbiome in general and the gut microbiome in particular have been associated not only to brain development and function, but also to the pathophysiology of brain aging and to neurodegenerative disorders such as Alzheimer's disease (AD), Parkinson's disease (PD), depression, or multiple sclerosis (MS) [...].

New Insights on the Nutrition Status and Antioxidant Capacity in Multiple Sclerosis Patients.

Multiple sclerosis (MS) is a multifactorial disease with unknown etiology. It is assumed to result from interplay between genetic and environmental factors, including nutrition. We hypothesized that there are differences in nutritional parameters between MS patients and healthy controls.

Clinical Outcomes of Escalation vs Early Intensive Disease-Modifying Therapy in Patients With Multiple Sclerosis.

Uncertainty remains about how aggressively to treat early multiple sclerosis. High-efficacy disease-modifying therapies (DMTs) are often reserved for individuals expressing poor prognostic features at baseline.

Targeting the S1P receptor signaling pathways as a promising approach for treatment of autoimmune and inflammatory diseases.

The past two decades of intense research have revealed a key role of the sphingolipid molecule sphingosine 1-phosphate (S1P) in regulating multiple physiological and pathophysiological processes including cell proliferation and survival, cell migration, inflammatory mediator synthesis and tissue remodeling. S1P mainly acts through five high-affinity G protein-coupled S1P receptors, which are ubiqu...

Effect of dosage reduction on peripheral blood lymphocyte count in patients with multiple sclerosis receiving long-term fingolimod therapy.

Of the 19 cases of fingolimod-associated progressive multifocal leukoencephalopathy (PML) reported worldwide by the end of 2017, 4 cases were from Japan. This may indicate that fingolimod sensitivity is higher in the Japanese population than in the western population because the fingolimod dosage used for the prevention of multiple sclerosis (MS) is the same in both populations. Therefore, the lab...

Clinical course of neuromyelitis optica spectrum disorder in a moroccan cohort.

Neuromyelitis optica spectrum disorder (NMOSD) was suggested to be more frequent and have specific features among populations from Africa or North Africa. However, we could not find any large study about NMOSD in an African population in the medical literature.

Clinical and MRI correlates of CSF neurofilament light chain levels in relapsing and progressive MS.

A major aim in MS field has been the search for biomarkers that enable accurate detection of neuronal damage. Besides MRI, recent studies have shown that neuroaxonal damage can also be tracked by neurofilament detection. Nevertheless, before widespread implementation, a better understanding of the principal contributors for this biomarker is of paramount importance. Therefore, we analyzed neurofil...

Validity of a multi-domain computerized cognitive assessment battery for patients with multiple sclerosis.

Computerized cognitive batteries may facilitate the integration of neuropsychological assessments into routine clinical care of patients with multiple sclerosis (PwMS).

Radiomics in multiple sclerosis and neuromyelitis optica spectrum disorder.

To develop and validate an individual radiomics nomogram for differential diagnosis between multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD).

Acute multiple sclerosis lesion pathology does not predict subsequent clinical course-a biopsy study.

Knowledge of the clinical outcome in tumefactive demyelination remains limited.

Foxp3+ regulatory T cells expression in neuromyelitis optica spectrum disorders.

Alterations in the frequency or function of regulatory T cells (Tregs), which play a critical role in the maintenance of peripheral immune tolerance, are known to be involved in the pathogenesis of several autoimmune diseases. Neuromyelitis optica spectrum disorders (NMOSD) are autoimmune inflammatory diseases of the central nervous system (CNS), of which the etiology and mechanisms underlying its...

Increased cerebrospinal fluid neurofilament light chain in central nervous system inflammatory demyelinating disease.

Central nervous system (CNS) inflammatory demyelinating disease (IDD) is an immune-mediated disease that is pathologically characterized by demyelination and inflammatory infiltration in the CNS and includes clinically isolated syndrome (CIS), multiple sclerosis (MS), and neuromyelitis optica spectrum disorders (NMOSD). IDD is usually characterized by variable symptoms, multivariate imaging, uncer...

Barriers against a successful MS treatment: The importance of effectiveness beyond efficacy.

Current multiple sclerosis (MS) therapeutic options have significantly increased treatment algorithm complexity. This urges physicians to take into account multiple factors in the decision-making process and make an even more thorough analysis of the risk-benefit balance. We carried out a descriptive review aiming to assess some factors that endanger the proper MS treatment fulfillment, focusing m...

Trial of intrathecal rituximab in progressive multiple sclerosis patients with evidence of leptomeningeal contrast enhancement.

Leptomeningeal inflammation is associated with increased cortical damage and worse clinical outcomes in MS. It may be detected on contrast-enhanced T2-FLAIR imaging as focal leptomeningeal contrast-enhancement (LME).

Prolonged cortical silent period is related to poor fitness and fatigue, but not tumor necrosis factor, in Multiple Sclerosis.

Poor fitness among people with Multiple Sclerosis (MS) aggravates disease symptoms. Whether low fitness levels accompany brain functioning changes is unknown.

Localization of near-infrared labeled antibodies to the central nervous system in experimental autoimmune encephalomyelitis.

Antibodies, including antibodies to the RNA binding protein heterogeneous nuclear ribonucleoprotein A1, have been shown to contribute to the pathogenesis of multiple sclerosis, thus it is important to assess their biological activity using animal models of disease. Near-infrared optical imaging of fluorescently labeled antibodies and matrix metalloproteinase activity were measured and quantified i...

Progressive Encephalomyelitis With Rigidity: Stiff Person Syndrome Variant Associated With Multiple Sclerosis.

Additional Rheumatologic Tests Critical in Patients with Systemic Sclerosis.

Tolerability, treatment satisfaction and quality of life outcomes in stable multiple sclerosis patients switched from injectable therapies to auto injected intramuscular interferon beta 1a: The SFERA study.

Interferon beta (IFNB) and Glatiramer acetate, long-term first line disease modifying treatments (DMTs) for multiple sclerosis (MS), have different injection frequencies crucial for injection site related side effects. We aimed at investigating whether switching to intramuscular IFNB-1a injected once/week with the Avonex®Pen™ device improves treatment tolerability and quality of life in stable ...

Time between expanded disability status scale (EDSS) scores.
