BACKGROUND Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease. During the course of the illness, malnutrition can occur and may shorten survival. The aim of our study was to determine whether clinical nutritional parameters that are used in daily practice are associated with prognosis and whether they can help guide therapeutic(More)
BACKGROUND Pathophysiological mechanisms involved in amyotrophic lateral sclerosis (ALS) are complex and none has identified reliable markers useful in routine patient evaluation. The aim of this study was to analyze the CSF of patients with ALS by (1)H NMR (Nuclear Magnetic Resonance) spectroscopy in order to identify biomarkers in the early stages of the(More)
Autism spectrum disorders (ASD) are a group of neurodevelopmental disorders resulting from multiple factors. Diagnosis is based on behavioural and developmental signs detected before 3 years of age, and there is no reliable biological marker. The purpose of this study was to evaluate the value of gas chromatography combined with mass spectroscopy (GC-MS)(More)
Amyotrophic lateral sclerosis (ALS) is an age-related neurodegenerative disorder that is believed to have complex genetic and environmental influences in the pathogenesis, but etiologies are unidentified for most patients. Until the major causes are better defined, drug development is directed at downstream pathophysiological mechanisms, themselves(More)
OBJECTIVE To describe the phenotype and phenotype-genotype correlations in patients with amyotrophic lateral sclerosis (ALS) with TARDBP gene mutations. METHODS French TARDBP+ patients with ALS (n = 28) were compared first to 3 cohorts: 737 sporadic ALS (SALS), 192 nonmutated familial ALS (FALS), and 58 SOD1 + FALS, and then to 117 TARDBP+ cases from the(More)
The covalent attachment of SUMO proteins (small ubiquitin-like modifier) to specific proteins or SUMOylation regulates their functional properties in the nucleus and cytoplasm of neurons. Recent studies reported dysfunction of the SUMO pathway in molecular and cellular abnormalities associated with amyotrophic lateral sclerosis (ALS). Furthermore, several(More)
Autism Spectrum Disorders (ASD) are a group of developmental disorders caused by environmental and genetic factors. Diagnosis is based on behavioral and developmental signs detected before 3 years of age with no reliable biological marker. The purpose of this study was to evaluate the potential use of a 2D NMR-based approach to express the global(More)
Amyotrophic lateral sclerosis (ALS) is characterized by the absence of reliable diagnostic biomarkers. The aim of the study was to (i) devise an untargeted metabolomics methodology that reliably compares cerebrospinal fluid (CSF) from ALS patients and controls by liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS); (ii) ascertain a(More)
Abnormal survival motor neuron 1 (SMN1)-copy number has been associated with an increased risk of amyotrophic lateral sclerosis (ALS) in French and Dutch population studies. The aim of this study was to determine whether SMN gene copy number increases the risk of ALS or modulates its phenotype in a cohort of Swedish sporadic ALS (SALS) patients. In all, 502(More)
In amyotrophic lateral sclerosis (ALS), motor neuron degeneration occurs simultaneously with systemic metabolic impairment and neuroinflammation. Playing an important role in the regulation of both phenomena, interleukin (IL)-6, a major cytokine of the inflammatory response has been proposed as a target for management of ALS. Although a pilot clinical trial(More)
