Multiple sclerosis in 2017: Progress in multiple sclerosis - from diagnosis to therapy
No full textIn 2017, extensive research into multiple sclerosis (MS) resulted in improved diagnostic criteria, development of biomarkers that enable monitoring of disease evolution and treatment response over time, and identification of novel genetic markers of disease susceptibility. In addition, 2017 saw the first successful clinical trials of remyelination strategies and treatments for progressive MS
Interrogating large multiple sclerosis registries and databases: what information can be gained?
Full text linkPurpose of review Although substantial progress has been made in understanding the natural history of multiple sclerosis (MS) and the development of new therapies, many questions concerning disease behavior and therapeutics remain to be answered. Data generated from real-world observational studies, based on large MS registries and databases and analyzed with advanced statistical methods, are offering the scientific community answers to some of these questions that are otherwise difficult or impossible to address. This review focuses on observational studies published in the last 2 years designed to compare the effectiveness of escalation vs. induction treatment strategies, to assess the effectiveness of treatment in pediatric-onset and late-onset MS, and to identify the clinical phenotype of secondary progressive (SP)MS. Recent findings The main findings originating from real-world studies suggest that MS patients who will qualify for high-efficacy disease-modifying therapies (DMTs) should be offered these as early as possible to prevent irreversible accumulation of neurological disability. Especially pediatric patients derive substantial benefits from early treatment. In patients with late-onset MS, sustained exposure to DMTs may result in more favorable outcomes. Data-driven definitions are more accurate in defining transition to SPMS than diagnosis based solely on neurologists' judgment. Patients, physicians, industry, and policy-makers have all benefited from real-world evidence based on registry data, in answering questions of diagnostics, choice of treatment, and timing of treatment decisions
Dengue fever in a multiple sclerosis patient taking Ocrelizumab
No full textDengue fever (DF) is an endemic infectious disease in tropical and subtropical regions. Ocrelizumab is a humanized monoclonal antibody that targets the CD20 antigen on B cells, which is approved for the treatment of both relapsing-remitting multiple sclerosis (RRMS) and primary-progressive multiple sclerosis (PPMS). We describe the favorable clinical outcome of DF in an RRMS patient treated with Ocrelizumab, who neither presented hemorrhagic or systemic shock symptoms nor reported neurological worsening
Interdisciplinary approach to opportunistic infections: staphylococcal meningitis in a patient with multiple sclerosis on treatment with dimethyl fumarate
No full textDear Editor,
Multiple Sclerosis (MS) is a chronic infammatory disease
of the central nervous system (CNS) representing a relevant
cause of disability in young adults. In the last 20 years, new
and emerging disease-modifying drugs (DMD) have been
introduced in clinical practice revolutionizing the natural
history of the disease [1]. However, immunomodulatory and
immunosuppressive treatments for MS are associated with
an increased risk of severe infections, which ranges from
0.2% to 2.6% [2
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Natalizumab reduces serum pro-angiogenic activity in MS patients
No full textAngiogenesis has been implicated in the pathobiology of multiple sclerosis (MS). Osteopontin exerts a pro-angiogenetic effect and is increased in body fluid of MS patients. To evaluate the effect of 1 year natalizumab treatment on serum pro-angiogenic activity and on plasma osteopontin levels in relapsing (RR) MS patients. Ten RRMS patients scheduled for natalizumab treatment were enrolled and evaluated at baseline and after 1-year natalizumab treatment. Pro-angiogenic activity was assessed by a chick embryo chorioallantoic membrane assay (CAM), osteopontin levels were evaluated by an enzyme-linked immunosorbent assay. Plasma and serum samples of 10 treatment-naïve RRMS and 10 healthy controls (HCs) were used as controls of baseline evaluations. Both treatment-naïve and natalizumab scheduled RRMS patients had higher baseline vessel density (22.0 ± 3.9 and 22.5 ± 2.6, p < 0.0001) and higher osteopontin levels (65.7 ± 24.3 ng/ml and 65.9 ± 16.6 ng/ml, p = 0.019 and p = 0.029, respectively) than HCs (9.0 ± 2.2; 48.5 ± 7.8 ng/ml, respectively). Baseline osteopontin levels and vessel density were significantly correlated (rs = 0.373, p = 0.043). After 1 year of treatment, the number of vessels and the osteopontin levels, were significantly reduced (11.9 ± 2.1, p < 0.005; 49.3 ± 20.0 ng/ml, p = 0.028). Our results suggest that natalizumab could exert its anti-inflammatory properties also by inhibiting the angiogenetic mechanisms in RRMS patients
Complexity of MS management in the current treatment era
Full text linkProdigious progress in the treatment of multiple sclerosis (MS) has occurred over the last 20 years, with the licensing of more than 15 novel and highly effective disease-modifying therapies (DMTs) to treat the disease. In this new complex scenario, an update of the previous therapeutic guidelines published by the American Academy of Neurology (AAN) in 2002 is needed for an appropriate and effective use of the old and new agents in clinical practice
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
