#1
REVIEW
Andrea Schampel, Stefanie Kuerten
Voltage-gated calcium channels (VGCCs) are widely distributed within the central nervous system (CNS) and presumed to play an important role in the pathophysiology of a broad spectrum of CNS disorders including Alzheimer's and Parkinson's disease as well as multiple sclerosis. Several calcium channel blockers have been in clinical practice for many years so that their toxicity and side effects are well studied. However, these drugs are primarily used for the treatment of cardiovascular diseases and most if not all effects on brain functions are secondary to peripheral effects on blood pressure and circulation...

In Brazil, inclusion and exclusion of health technologies within the Unified Health System (SUS) is the responsibility of the National Committee for Health Technology Incorporation (CONITEC). A recent Cochrane systematic review demonstrated that intramuscular interferon beta 1a (IFN-β-1a-IM) was inferior to the other beta interferons (IFN-βs) for multiple sclerosis (MS). As a result, CONITEC commissioned an analysis to review possible disinvestment within SUS. The objective of this paper is to describe the disinvestment process for IFN-β-1a-IM in Brazil...

REVIEW
Alberto Gajofatto
Siponimod (BAF312) is a synthetic molecule belonging to the sphingosine-1-phosphate (S1P) modulator family, which has putative neuroprotective properties and well-characterized immunomodulating effects mediated by sequestration of B and T cells in secondary lymphoid organs. Compared to fingolimod (ie, precursor of the S1P modulators commercially available for the treatment of relapsing-remitting [RR] multiple sclerosis [MS]), siponimod exhibits selective affinity for types 1 and 5 S1P receptor, leading to a lower risk of adverse events that are mainly induced by S1P3 receptor activation, such as bradycardia and vasoconstriction...

REVIEW
Tommaso Croese, Roberto Furlan
Extracellular vesicles (EVs) are released by all neural cells, including neurons, oligodendrocytes, astrocytes, and microglia. The lack of adequate technology has not halted neuroscientists from investigating EVs as a mean to decipher neurodegenerative disorders, still in search of comprehensible pathogenic mechanisms and efficient treatment. EVs are thought to be one of ways neurodegenerative pathologies spread in the brain, but also one of the ways the brain tries to displace toxic proteins, making their meaning in pathogenesis uncertain...

INTRODUCTION: A Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired, or non-hereditary, chronic demyelinating neuropathy. Currently, there is no reliable molecular biomarker that can identify CIDP patients as well as monitor disease severity. MATERIAL AND METHODS: We measured serum levels of endothelin-1 (ET-1), a factors involved in vasoconstrictive, inflammatory and nerve regenerative processes, in the serum of 20 CIDP, 21 acute inflammatory demyelinating polyneuropathy (AIDP), 37 multiple sclerosis (MS), and 10 Alzheimer's disease (AD) patients, as well as 26 healthy control (HC) subjects...

BACKGROUND: Data on the incidence of multiple sclerosis (MS) on the national level is scarce. We aimed to estimate the incidence of MS in Germany and to compare different MS case definitions based on claims data. METHODS: We conducted a cohort study with the German Pharmacoepidemiological Research Database in 2012 and calculated age- and gender-standardized incidence rates (sIRs) for 3 case definitions. In addition, the effect of stepwise reduction of the look-back period without MS diagnosis on the incidence rate was evaluated...

Spasticity of spinal or cerebral origin is frequently treated with baclofen. Treatment interruption initially results in rebound spasticity; life-threatening withdrawal symptoms may follow. Severe rebound spasticity of leg muscles occurred in a multiple sclerosis patient after a 10-hour long perioperative pause of oral baclofen intake. In a subsequent spine surgery, recurrence was prevented by substituting a cumulative 12-hour oral baclofen dose with an intraoperative intrathecal injection. Administration of intrathecal baclofen during prolonged surgery in patients dependent on oral baclofen may improve patient comfort and prevent early withdrawal symptoms...

Ticks are tiny crawling bugs in the spider family that feed by sucking blood from animals. They are second only to mosquitoes as vectors of human disease, both infectious and toxic. Infected ticks spread over a hundred diseases, some of which are fatal if undetected. They spread the spirochete (which multiplies in the insect's gut) with a subsequent bite to the next host. We describe the only reported cases of peri ocular tick bite from India that presented to us within a span of 3 days and its management. Due suspicion and magnification of the lesions revealed the ticks which otherwise masqueraded as small skin tags/moles on gross examination...

Multiple sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system. Currently, there is no drug available to cure this kind of disease. Diosgenin is a plant-derived steroid saponin. A previous study in our lab revealed that diosgenin can promote oligodendrocyte progenitor cell differentiation and accelerate remyelination. In the present study, we found that diosgenin dose-dependently alleviated the progression of experimental autoimmune encephalomyelitis with reduced central nervous system inflammation and demyelination...

BACKGROUND: Metabolic reprogramming is shaped to support specific cell functions since cellular metabolism controls the final outcome of immune response. Multiple sclerosis (MS) is an autoimmune disease resulting from loss of immune tolerance against central nervous system (CNS) myelin. Metabolic alterations of T cells occurring during MS are not yet well understood and their studies could have relevance in the comprehension of the pathogenetic events leading to loss of immune tolerance to self and to develop novel therapeutic strategies aimed at limiting MS progression...

BACKGROUND: Multiple sclerosis (MS) is a severe and common autoimmune disorder of the central nervous system. Despite the availability of several novel treatment options, the disease is still poorly controlled, since the pathophysiological mechanisms are not fully understood. METHODS: We tested the role of the acid sphingomyelinase/ceramide system in a model of MS, i.e. experimental autoimmune encephalomyelitis (EAE). Mice were immunized with myelin-oligodendrocyte glycoprotein and the development of the disease was analyzed by histology, immunological tests and clinical assessment in wildtype and acid sphingomyelinase (Asm)-deficient mice...

BACKGROUND: Interferon-β has been approved for the treatment of relapsing-remitting (RR) multiple sclerosis (MS), whereas its efficacy in preventing long-term disability and conversion to secondary progressive (SP) MS is still debated. We aim to compare long-term clinical evolution of newly-diagnosed RRMS patients treated with different Interferon-β formulations. METHODS: 507 patients were included in the analysis and followed-up for 8.5 ± 3.9 years. 37.6% were treated with subcutaneous Interferon-β1a 44mcg, 33...

BACKGROUND: Progressive multiple sclerosis is a chronic autoimmune condition of unknown aetiology and few therapeutic options. Human exposure to aluminium has been linked with multiple sclerosis and affected individuals are known to excrete unusually high amounts of aluminium in their urine. Silicon-rich mineral waters facilitate the removal of aluminium from the body in urine and herein we have tested their efficacy in affecting urinary excretion of aluminium in individuals diagnosed with secondary progressive multiple sclerosis (SPMS)...

BACKGROUND: Launched in the US in 2012, Choosing Wisely(®) is a campaign promoted by the American Board of Internal Medicine (ABIM) Foundation with the goal of improving healthcare effectiveness by avoiding wasteful or unnecessary medical tests, treatments and procedures. It uses concise recommendations produced by national medical societies to start discussions between physicians and patients on the relevance of these services as part of a shared decision-making process. The Multiple Sclerosis Focus Group (Groupe de Reflexion Autour de la Sclérose en Plaques; GRESEP) undertook a pilot study to assess the relevance and feasibility of this approach in the management of multiple sclerosis (MS) in France...

Multiple sclerosis (MS) and the corresponding animal model, experimental autoimmune encephalomyelitis (EAE), are chronic neuroinflammatory autoimmune diseases. Increased activation of CD4+T cells, especially the Th1 and Th17 subsets, is thought to play a causal role in this disease. IFN-β is widely used in the treatment of MS and is found to decrease IL-17 and OPN production in MS patients and EAE mice. However, a definitive molecular mechanism has not yet been fully elucidated. In this study, we investigated the immunomodulatory effect of IFN-β on the EAE model...
