New Warning for the Multiple Sclerosis Drug Alemtuzumab

The Food and Drug Administration has added a black box warning for alemtuzumab (Lemtrada) stating that the drug, used in the treatment of relapsing multiple sclerosis, may cause ischemic and hemorrhagic stroke and cervicocephalic arterial dissection, rare but serious adverse effects.Nurses should teach patients prescribed this medication to recognize and seek emergency medical care if they develop any signs or symptoms of stroke.

AbstractGadolinium-based contrast agents (GBCAs) increase lesion detection and improve disease characterization for many cerebral pathologies investigated with MRI. These agents, introduced in the late 1980s, are in wide use today. However, some non-ionic linear GBCAs have been associated with the development of nephrogenic systemic fibrosis in patients with kidney failure. Gadolinium deposition has also been found in deep brain structures, although it is of unclear clinical relevance. Hence, new guidelines from the International Society for Magnetic Resonance in Medicine advocate cautious use of GBCA in clinical and resea...

Abstract Treatment options for multiple sclerosis (MS) have improved in the past 20 years, with new oral disease-modifying drugs and monoclonal antibodies becoming available. The success seen with these drugs in MS, and their various mechanisms of action, has led to them being investigated in other neurological and psychiatric disorders. This review article summarises the ongoing and completed studies of MS drugs in neurological and psychiatric conditions other than MS. The most promising results are for interferon beta in human T cell leukaemia virus 1 associated myelopathy/tropical spastic paraparesis and glioma...

Conclusion: Intracranial artery calcification is common in patients with ischemic cerebrovascular disease and the intracranial carotid artery is most frequently affected. Intracranial arterial calcifications might be associated with imaging markers of SVD and are highly correlated with WMHs, lacunes, and CMBs. Quantification of calcification on CT provides additional information on the pathophysiology of SVD. Intracranial arterial calcification could act as a potential marker of SVD. Introduction Atherosclerosis is a systemic vascular process that is considered a major cause of cerebrovascular and cardiovascular di...

Early recognition of the underlying causes of the neurological symptoms can facilitate timely treatment and improve the prognosis. This review highlights the clinical manifestations of primary systemic vasc...

Endothelial cells of the central nervous system over-express surface proteins during neurological disorders, either as a cause, or a consequence, of the disease. Since the cerebral vasculature is easily accessible by large contrast-carrying particles, it constitutes a target of choice for molecular magnetic resonance imaging (MRI). In this review, we highlight the most recent advances in molecular MRI of brain endothelial activation and focus on the development of micro-sized particles of iron oxide (MPIO) targeting adhesion molecules including intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (...

Conclusions Given the high risk for stroke in this MS population and the observed complexity among the coincident common risk factors for circulatory diseases, the high risk for type 1 diabetes and common infections raise a need to recognize patients at risk with these conditions and with the other known risk factors such as metabolic syndrome and smoking. The survival disadvantage related to circulatory diseases observed in general population is true also in MS and should be recognized to reduce the burden of disease and premature mortality in MS.

This article is a practical guide to identifying uncommon causes of stroke and offers guidance for evaluation and management, even when large controlled trials are lacking in these rarer forms of stroke. Recent Findings: Fabry disease causes early-onset stroke, particularly of the vertebrobasilar system; enzyme replacement therapy should be considered in affected patients. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), often misdiagnosed as multiple sclerosis, causes migraines, early-onset lacunar strokes, and dementia. Moyamoya disease can cause either ischemic or he...

Publication date: Available online 28 April 2016 Source:Progress in Neurobiology Author(s): Stéphanie Hostenbach, Miguel D’haeseleer, Ron Kooijman, Jacques De Keyser In the normal central nervous system, endothelin-1 (ET-1) is found in some types of neurons, epithelial cells of the choroid plexus, and endothelial cells of microvessels, but it is usually not detectable in glial cells. However, in different pathological conditions, astrocytes adapting a reactive phenotype express high levels of ET-1 and its receptors, mainly the ETB receptor. ET-1 released by reactive astrocytes appears mainly to have neur...
