OBJECTIVE To determine the relation between baseline MRI and both conversion to multiple sclerosis (MS) and development of disability in a cohort of patients with clinically isolated syndromes (CIS). METHODS From 1995 to 1998, 175 consecutive patients with CIS underwent brain MRI within 3 months of their first attack and again 12 months and 5 years later.(More)
OBJECTIVE Many patients with multiple sclerosis (MS) are currently receiving treatment with interferon (IFN)-beta. Early identification of nonresponder patients is crucial to try different therapeutic approaches. We investigated various criteria of treatment response to assess which criterion better identifies patients with a poor response. METHODS We(More)
BACKGROUND To evaluate whether oligoclonal bands (OB) add information to MRI in predicting both a second attack and development of disability in patients with clinically isolated syndromes (CIS). METHODS From 1995 to 2006, 572 patients with CIS were included in a prospective study. Patients underwent brain MRI and determination of OB within 3 months of(More)
BACKGROUND Recently developed diagnostic criteria for MS (McDonald criteria) indicate that in patients with a single demyelinating episode (clinically isolated syndromes [CIS]), evidence for dissemination in space and time, essential for diagnosis, may be provided by MRI. OBJECTIVE To assess the usefulness of these new criteria in patients with CIS(More)
Clinical trials with interferons in relapsing-remitting multiple sclerosis have shown a modest effect on disability using fixed definitions of treatment failure to measure disease progression. However, in the course of the disease, treatment failure may be influenced by interrater variability and frequent remissions. Thus, the purpose of this study was to(More)
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)
BACKGROUND Number of baseline lesions has been shown to predict future attacks and disability in clinically isolated syndromes (CIS). OBJECTIVE To investigate the role of baseline infratentorial lesions in long-term prognosis. METHODS Subjects were included in a prospective cohort of patients with CIS. Patients underwent brain MRI within 3 months after(More)
Osteopontin (OPN) is a pleiotropic integrin binding protein with functions in cell-mediated immunity, inflammation, tissue repair, and cell survival. Recent studies have shown that OPN may play an important role in the pathogenesis of experimental autoimmune encephalomyelitis and multiple sclerosis (MS). Here, we investigated the plasma levels of OPN in 221(More)
Optic neuritis presentations are thought to have a better prognosis. The aim of our study was to compare conversion to multiple sclerosis on the different topographies of CISs. We prospectively evaluated 320 patients with CISs (123 with optic neuritis, 78 with brainstem syndromes, 89 with spinal cord syndromes, and 30 with other topographies) who were(More)
