Natural history studies have identified factors that predict evolution to multiple sclerosis or risk of disability accumulation over time. Although these studies are based on large multicentre cohorts with long follow-ups, they have limitations such as lack of standardized protocols, a retrospective data collection or lack of a systematic magnetic resonance(More)
OBJECTIVE To evaluate the usefulness of SPECT in assessing damage to the pre-synaptic dopaminergic system in Huntington's disease (HD) using [(123)I]-FP-CIT (DaTSCAN), a selective radioligand with regulatory approval as the diagnostic test for investigating functional dopaminergic neuron loss in the striatum in Parkinson's disease. METHODS We studied(More)
OBJECTIVE To study the contribution of the symptomatic lesion in establishing multiple sclerosis (MS) diagnosis and prognosis. METHODS We performed an observational study based on a prospective clinically isolated syndrome (CIS) cohort of 1,107 patients recruited for clinical and brain MRI follow-up from 1995 to 2014. Eligible patients (n = 954) were(More)
High mobility group box protein 1 (HMGB1) is a transcriptional regulator that is receiving increasing attention in autoimmune disorders including multiple sclerosis (MS). Here, we investigated the role of HMGB1 in the peripheral blood compartment from MS patients. HMGB1 mRNA expression levels were determined by PCR in peripheral blood mononuclear cells(More)
To illustrate the potential of [I]-FP-CIT SPECT DaTSCAN® in investigating the progression of presynaptic dopaminergic degeneration in Huntington disease (HD), we performed a 2-year follow-up [I]-FP-CIT study on 4 HD patients, evaluating the SPECT imaging based on qualitative and semiquantitative analysis. The mean annual decline in [I]-FP-CIT uptake in(More)
