PURPOSE: To examine the long-term persistence to the first-line injectable disease-modifying therapies (DMTs) for multiple sclerosis (MS) and to identify the factors associated with nonpersistence. PATIENTS AND METHODS: We used population-based administrative data from Manitoba, Canada. All adult subjects who were diagnosed with MS and dispensed a first-line injectable DMT (beta-interferon-1b, beta-interferon-1a, and glatiramer acetate) between 1996 and 2011 and had a minimum of 1 year of follow-up were included...

A 44-year-old woman with multiple sclerosis (MS) receiving interferon (IFN)-beta-1a treatment was admitted to a local hospital for severe icterus and liver injury. She was transferred to our university hospital because fulminant hepatitis (FH) was suspected. She was diagnosed with acute-type FH based on hepatic coma, severe liver injury and liver failure, and she received plasma exchange and continuous hemodiafiltration therapy. On hospital day 6, she died from liver failure despite intensive care. An autopsy revealed histological findings consistent with FH...

INTRODUCTION: 'No evidence of disease activity' (NEDA) is increasingly used as a treatment target with disease-modifying drugs for relapsing multiple sclerosis. METHODS: This post-hoc analysis of the randomised EVIDENCE trial compared interferon beta-1a injected subcutaneously three times weekly (IFN β-1a SC tiw) with interferon β-1a injected intramuscularly once weekly (IFN β-1a IM qw) on NEDA and clinical activity-free (CAF) status. The influence of the frequency of magnetic resonance imaging (MRI) scanning on NEDA and the effect of baseline T1 gadolinium-enhancing (Gd+) lesions on NEDA and CAF were also investigated...

INTRODUCTION: Although it has been shown that immunomodulatory therapies (IMTs) in multiple sclerosis (MS) can modify the course of the disease by reducing the relapse rate and delaying the progression of disability, no study comparing IMTs head-to-head in terms of clinical, radiological, and electrophysiological changes is available. We aimed to investigate the effects of interferon-beta (IFN-B) 1b, IFN-B-1a subcutaneous (sc), IFN-B-1a intramuscular (im), and glatiramer acetate (GA) therapies on clinical, electrophysiological, and radiological findings...

Susac syndrome is a rare autoimmune disorder characterised by the clinical triad of encephalopathy, retinopathy (branch retinal artery occlusions) and hearing loss. The diagnosis of Susac syndrome may be difficult initially, and it is not uncommon for patients with Susac syndrome to be misdiagnosed with multiple sclerosis. In this case report, we describe a patient who was diagnosed as having multiple sclerosis for three years, with further deterioration after starting treatment with interferon beta-1a. The patient had the triad of encephalopathy, branch retinal artery occlusions and sensorineural hearing loss...

BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, affecting 2.5 million people globally and 400,000 people in the United States. While no cure exists for MS, the goal is to manage the disease using disease-modifying therapies (DMTs), which have been shown to slow disease progression and prevent relapses. Relapsing-remitting MS (RRMS) is the most common form of MS at the time of diagnosis. Peginterferon beta-1a (PEG) and alemtuzumab (ALT) were recently approved and have demonstrated good clinical outcomes, including reduced relapse rates in clinical trials...

OBJECTIVE: We aimed to evaluate clinical and diagnostic features of central and peripheral immune-mediated demyelinating disease (CPID) in allogeneic hematopoietic stem cell transplantation (aHSCT) recipients. BACKGROUND: CPID refers to the late-onset, immune-mediated neurological complications following aHSCT, when other frequent differential diagnoses have been ruled out, and when symptoms and signs of systemic GvHD manifestations are absent. METHODS: Case records at the University of Tuebingen, between 2001 and 2015, were screened to identify patients with CPID after aHSCT...

BACKGROUND: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a disease that causes progressive or relapsing and remitting weakness and numbness. It is probably caused by an autoimmune process. Immunosuppressive or immunomodulatory drugs would be expected to be beneficial. This review was first published in 2003 and has been updated most recently in 2016. OBJECTIVES: To assess the effects of immunomodulatory and immunosuppressive agents other than corticosteroids, immunoglobulin, and plasma exchange in CIDP...

BACKGROUND: The treatment of multiple sclerosis has changed over the last 20 years. The advent of disease-modifying drugs in the mid-1990s heralded a period of rapid progress in the understanding and management of multiple sclerosis. With the support of magnetic resonance imaging early diagnosis is possible, enabling treatment initiation at the time of the first clinical attack. As most of the disease-modifying drugs are associated with adverse events, patients and clinicians need to weigh the benefit and safety of the various early treatment options before taking informed decisions...

Melioidosis is an underreported infectious disease, caused by the Gram-negative bacterium Burkholderia pseudomallei. Understanding the disease susceptibility and pathogenesis is crucial for developing newer diagnostic and therapeutic strategies for this life-threatening infection. In this study, we aimed to analyze the gene expression levels of important cytokines in melioidosis patients and establish useful correlates with disease biomarkers compared to cases of sepsis infection caused by other pathogens and healthy individuals...

Natalizumab (NTZ) is an effective treatment for patients with highly active relapsing remitting multiple sclerosis (MS). However, when the therapy must be interrupted, it is important to anticipate the withdrawal to avoid reactivation or disease rebound. Described here is the case of a 35-year-old woman, with a past history of beta thalassemia, bulimia and asthma, who was diagnosed with MS at age 26. She was treated initially with first-line subcutaneous (sc) immunomodulatory treatments. However, due to liver toxicity, interferon beta-1a sc was interrupted and replaced by glatiramer acetate treatment, which was well tolerated and used for several years...

BACKGROUND: Adherence to disease-modifying drugs (DMDs) is one of the key factors for achieving optimal clinical outcomes. Rebismart(®) is an injection device for subcutaneous administration of interferon beta-1a (INF β-1a) that is also able to monitor adherence objectively. The aim of this study was to describe adherence to INF β-1a using the said electronic autoinjection device and to explore the relationship between adherence and relapses in a Spanish cohort. METHODS: This is a retrospective observational study in which 110 Spanish patients self-administered INF β-1a subcutaneously using an electronic autoinjection device between June 2010 and June 2015...

Brain atrophy occurs at a faster rate in patients with multiple sclerosis (MS) than in healthy individuals. In three randomized, controlled, phase III trials, fingolimod reduced the annual rate of brain volume loss (BVL) in patients with relapsing MS (RMS) by approximately one-third relative to that in individuals receiving placebo or intramuscular interferon beta-1a. Analysis of brain volume changes during study extensions has shown that this reduced rate of BVL is sustained in patients with RMS receiving fingolimod continuously...

BACKGROUND: Medications and their prices are key issues for healthcare. Although access to medicines at affordable prices had been specified as a key objective of the European Health Policy, it seems that these goals have not been achieved. Therefore, we attempted an evaluation of affordability of selected medicines at full prices. METHODS: The analysis concerned 2012 and was conducted between 2013 and 2015 in all the European Union (EU) countries divided into 3 groups depending on the date of their accession to the EU...

Hepatitis delta virus (HDV) is a minimalistic satellite virus of hepatitis B virus (HBV). HBV/HDV co-infection, i.e. "hepatitis D", is the most severe form of viral hepatitis. No effective therapy for HDV infection is available partly due to the fact that HDV is a highly host-dependent virus devoid of any potentially drugable enzyme encoded in its small genome. In this study we present a semi-automated method to evaluate HDV infection and replication under the influence of different drugs. We utilized a Huh-7/hNTCP cell culture based system in a 96-well plate format, an automated microscope and image acquisition as well as analysis with the CellProfiler software to quantify the impact of these drugs on HDV infection...

Introduction of a chemical change to one or more amino acids in a protein's polypeptide chain can result in various effects on its higher-order structure (HOS) and biophysical behavior (or properties). These effects range from no detectable change to significant structural or conformational alteration that can greatly affect the protein's biophysical properties and its resulting biological function. The ability to reliably detect the absence or presence of such changes is essential to understanding the structure-function relationship in a protein and in the successful commercial development of protein-based drugs (biopharmaceuticals)...

Antibodies against biopharmaceuticals (anti-drug antibodies, ADA) have been a well-integrated part of the clinical care of multiple sclerosis (MS) in several European countries. ADA data generated in Europe during the more than 10 years of ADA monitoring in MS patients treated with interferon beta (IFNβ) and natalizumab have been pooled and characterized through collaboration within a European consortium. The aim of this study was to report on the clinical practice of ADA testing in Europe, considering the number of ADA tests performed and type of ADA assays used, and to determine the frequency of ADA testing against the different drug preparations in different countries...
