Replication of association of CHRNA4 rare variants with sporadic amyotrophic lateral sclerosis: the Italian multicentre study.

Amyotroph Lateral Scler 2012 Oct 8;13(6):580-4. Epub 2012 Aug 8.

Istituto di Neurologia, Università Cattolica del Sacro Cuore, Roma, Italy.

Neuronal nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels widely expressed throughout the mammalian brain, including bulbar and spinal motor neurons. They are involved in neuroprotection and in control of release of many neurotransmitters, including glutamate. Previous data raised the hypothesis that rare variants in the region coding the intracellular loop subunits of nAChRs might represent one of several genetic risk factors for SALS. Read More

NEuroMuscular Omnicentre, Fondazione Serena Onlus, Niguarda Ca' Granda Hospital, Department of Psychology, Università Cattolica del Sacro Cuore, Milan, Italy.

Clinical experience has shown an increase of behavioural and mood symptoms, especially in the areas of aggressiveness, sexuality and obsessiveness, during the late stages of ALS. The lack of conclusive data concerning these symptoms prompted us to assess the psychological aspects of ALS patients in advanced stages of the disease. Moreover, we evaluated the personality of their caregivers in order to analyse the relationship between the pair. Read More

Non-steroidal anti-inflammatory drugs and amyotrophic lateral sclerosis: results from five prospective cohort studies.

Amyotroph Lateral Scler 2012 Oct 7;13(6):573-9. Epub 2012 Aug 7.

Department of Nutrition, Harvard School of Public Health, Boston, Massachusetts 02155, USA.

Animal and pathological studies suggest that inflammation may contribute to amyotrophic lateral sclerosis (ALS) pathology and that non-steroidal anti-inflammatory drugs (NSAIDs) might be protective. However, there are no prospective data on the relation between NSAID use and ALS risk in humans. The relation between NSAID use and ALS risk was explored in five large prospective cohort studies (the Nurses' Health Study, the Health Professionals Follow-up Study, the Cancer Prevention Study II Nutrition Cohort, the Multiethnic Cohort Study, and the National Institutes of Health - AARP Diet and Health Study).

Functional improvement in mouse models of familial amyotrophic lateral sclerosis by PEGylated insulin-like growth factor I treatment depends on disease severity.

Amyotroph Lateral Scler 2012 Sep 7;13(5):418-29. Epub 2012 Aug 7.

F. Hoffmann-La Roche Ltd., CNS Pharma Research & Early Development, Basel, Switzerland.

Insulin-like growth factor I (IGF-I) has been successfully tested in the SOD1-G93A mouse model of familial amyotrophic lateral sclerosis (ALS) and proposed for clinical treatment. However, beneficial effects required gene therapy or intrathecal application. Circumventing the dosing issues we recently found that polyethylene glycol (PEG) modified IGF-I (PEG-IGF-I) modulated neuromuscular function after systemic application, and protected against disease progression in a motor neuron disease model.

Predictors of emergent feeding tubes and tracheostomies in amyotrophic lateral sclerosis (ALS).

Amyotroph Lateral Scler 2012 May;13(3):318-25

Robert Wood Johnson Foundation Veterans Affairs Clinical Scholars Program, University of Pennsylvania, Philadelphia, Pennsylvania, USA.

Predictable decline in ALS makes unplanned gastrostomy and tracheostomy avoidable. We determined whether gastrostomy or tracheostomy insertion during emergent hospitalization is associated with patient or hospital characteristics, changed Medicare policy in 2001, or proximity to specialized ALS care. We performed a retrospective analysis of hospitalizations and procedures for ALS/MND patients in Pennsylvania between 1996 and 2009. Read More

Misfolded SOD1 and ALS: zeroing in on mitochondria.

Amyotroph Lateral Scler 2012 Jun 3;13(4):333-40. Epub 2012 Apr 3.

Centre d'excellence en neuromique de l'Université de Montréal, Centre de recherche du CHUM (CRCHUM), Montréal, QC, Canada.

Mutations in SOD1, causative for a subset of familial ALS cases, are associated with the formation of non-normal SOD1 conformers. Recent studies have defined this pool of SOD1 as misfolded and new antibodies have been developed to selectively detect misfolded SOD1 in vivo and in vitro. We will review these new tools and expand on the evidence demonstrating mitochondria as a common intersecting point for misfolded SOD1. Read More

Is head trauma a risk factor for amyotrophic lateral sclerosis? An evidence based review.

Amyotroph Lateral Scler 2012 Jun 16;13(4):351-6. Epub 2012 Mar 16.

Tufts University School of Medicine/Baystate Medical Center, Springfield, MA 01199, USA.

Our objective was to evaluate the epidemiological literature regarding the association between trauma to the head and ALS, in order to determine if trauma to the head is a risk factor for ALS. A Medline literature search was conducted for the period between 1980 and October 2010 using the search terms: ('head trauma' OR 'head injury') AND (ALS OR 'amyotrophic lateral sclerosis' OR MND OR 'motor neuron disease'). The references of primary articles and reviews were checked to assure completeness of the search. Read More

Blood pressure measurements in a transgenic SOD1-G93A mouse model of amyotrophic lateral sclerosis.

Amyotroph Lateral Scler 2012 Oct 16;13(6):509-13. Epub 2012 Mar 16.

The Department of Physiology and Pharmacology, Sackler School of Medicine, Tel-Aviv University and the Department of Neurology, Tel-Aviv Medical Centre, Israel.

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive loss of motor neurons, but non-motor manifestations including autonomic dysfunction have been reported. To better understand the autonomic involvement in ALS we measured blood pressure (BP) changes. We evaluated blood pressure (BP) in a transgenic (TG) SOD1-G93A mouse model of ALS. Read More

A systematic review of behavioural changes in motor neuron disease.

Amyotroph Lateral Scler 2012 Oct 16;13(6):493-501. Epub 2012 Mar 16.

Department of Neurology, Academic Medical Centre, University of Amsterdam, The Netherlands.

Motor neuron disease (MND) and the behavioural variant of frontotemporal dementia (bvFTD) are thought to be part of a disease spectrum. There is uncertainty about the frequency and characteristics of behavioural changes in MND, and similarly, about a relation between bvFTD and the site of onset of MND. Our aim was to perform a systematic review of the publications on behavioural changes in MND. Read More

Effect of genetic background on onset and disease progression in the SOD1-G93A model of amyotrophic lateral sclerosis.

Amyotroph Lateral Scler 2012 May 16;13(3):302-10. Epub 2012 Mar 16.

Group of Neuroplasticity and Regeneration, Institute of Neurosciences and Department of Cell Biology, Physiology and Immunology, Universitat Autònoma de Barcelona, Bellaterra.

Knowledge of the potential effect of genetic background in disease models is important. The SOD1-G93A transgenic mouse is the most widely used model in amyotrophic lateral sclerosis (ALS). Since these animals show considerable variability both in the onset and the progression of the disease, this study aimed to characterize the potential differences between the two most widely used strains, C56BL/6 (B6) and B6SJL.

Does interneuronal dysfunction contribute to neurodegeneration in amyotrophic lateral sclerosis?

Amyotroph Lateral Scler 2012 May 16;13(3):245-50. Epub 2012 Mar 16.

Oxford University Nuffield Department of Clinical Neurosciences, John Radcliffe Hospital, Oxford, UK.

Amyotrophic lateral sclerosis (ALS) is typically regarded as a sporadic neurodegenerative disorder that results in a catastrophic failure of the motor system, with characteristically variable involvement of upper and lower motor neuronal populations. A wide range of evidence from clinical, histological, genetic, neurophysiological, neuroimaging and neuropsychological studies, suggests that a loss of central nervous system inhibitory neuronal influence is a contributing factor in ALS pathogenesis. This loss of inhibitory function points intuitively to an 'interneuronopathy', with natural differences in cortical and spinal inhibitory networks reflected in the hitherto unexplained variable compartmentalization of pathology within upper and lower motor neuron populations.

Reducing systemic hypermetabolism by inducing hypothyroidism does not prolong survival in the SOD1-G93A mouse.

Amyotroph Lateral Scler 2012 Jun 16;13(4):372-7. Epub 2012 Mar 16.

Department of Neurology and Department of Medicine, Division of Endocrinology, Beth Israel Deaconess Medical Center, Boston, MA 02215, USA.

ALS is commonly associated with a hypermetabolic state. In this study, we assess whether inhibition of this hypermetabolism via the induction of hypothyroidism can forestall disease onset and prolong life in the SOD1-G93A mouse. We treated a cohort of 16 SOD1-G93A mice with methimazole, a potent inhibitor of thyroid hormone synthesis and followed a second group of 23 untreated littermate control animals from approximately five weeks of age onward.

Inappropriately chelated iron in the cerebrospinal fluid of amyotrophic lateral sclerosis patients.

Amyotroph Lateral Scler 2012 Jun 16;13(4):357-62. Epub 2012 Mar 16.

Department of Biophysical Chemistry, Faculty of Physical Chemistry, University of Belgrade, Belgrade.

ALS is characterized by oxidative damage in the brain and cerebrospinal fluid, which is exerted by pro-oxidative activity of iron. Such activity of iron can be drastically increased in the presence of inappropriate iron ligands that catalyze redox cycling of iron, thereby promoting hydroxyl radical generation. The aim of our study was to determine the relative level of inappropriate iron ligands in the cerebrospinal fluid of ALS patients. Read More

A novel TARDBP insertion/deletion mutation in the flail arm variant of amyotrophic lateral sclerosis.

Amyotroph Lateral Scler 2012 Sep 16;13(5):465-70. Epub 2012 Mar 16.

Northcott Neuroscience Laboratory, ANZAC Research Institute, Sydney, NSW, Australia.

Phenotypic variation in amyotrophic lateral sclerosis (ALS) is common, and one atypical form is the flail arm variant (FAV). Some classic ALS patients carry TARDBP mutations, and so we sought to establish whether TARDBP mutations are also present in the FAV of ALS. Mutation analysis of TARDBP, the gene encoding TDP-43, was performed in cohorts of classic and FAV ALS patients. Read More
