Natalizumab inhibits lymphocyte trafficking across the blood–brain barrier, reducing relapse rates by up to 70% in patients with relapsing-remitting multiple sclerosis (RRMS). Discontinuation of the drug, usually due to pregnancy or risk of progressive multifocal leukoencephalopathy (PML), can trigger the return of disease activity or, occasionally, a fulminant immune reconstitution inflammator...

Multiple sclerosis (MS) is an autoimmune disease that affects the body's central nervous system. Around 90% of MS sufferers are diagnosed with relapsing-remitting MS (RRMS). We used ELISA to measure IgG, IgA, and IgM antibodies against linear epitopes of human and plant aquaporins (AQP4) as well as neural antigens in RRMS patients and controls to determine whether patients suffering from RRMS h...

Alemtuzumab, a highly effective treatment for relapsing remitting multiple sclerosis (RRMS), induces lymphopenia especially of CD4+ T cells. Here, we report the atypical CD4+ T population behaviour of two patients with persistent disease activity despite repeated alemtuzumab treatments. Whereas lymphocytes count decreased and fluctuated accordingly to alemtuzumab administration, their CD4+ cell...

Multiple sclerosis (MS) is a chronic neurological disease that is a major cause of disability in young adults in Europe and North America [1]. The clinical course of MS is unpredictable and varies individually, with some patients experiencing minimal impairment. The majority of patients have a form of MS referred to as relapsing-remitting MS (RRMS) characterized by periods of clinical stability...

UNLABELLED Although neuromyelitis optica (NMO) is known to be a more severe disease than relapsing-remitting multiple sclerosis (RRMS), few studies comparing both conditions in a single center have been done. METHODS Comparison of our previously published cohort of 41 NMO patients with 177 RRMS patients followed in the same center, from 1994 to 2007. RESULTS Mean age of onset was 32.6 for N...

INTRODUCTION Quantitative T2 mapping may provide an objective biomarker for occult nervous tissue pathology in relapsing-remitting multiple sclerosis (RRMS). We applied a novel echo modulation curve (EMC) algorithm to identify T2 changes in normal-appearing brain regions of subjects with RRMS (N = 27) compared to age-matched controls (N = 38). METHODS The EMC algorithm uses Bloch simulations ...

OPINION STATEMENT Despite the development of several injectable or oral treatments for relapsing-remitting multiple sclerosis (RRMS), it remains difficult to treat patients with aggressive disease, and many of these continue to develop severe disability. During the last two decades autologous hematopoietic stem cell transplantation (aHSCT) has been explored with the goal to eliminate an aberran...

Focal demyelinated lesions, diffuse white matter (WM) damage, and gray matter (GM) atrophy influence directly the disease progression in patients with multiple sclerosis. The aim of this study was to identify specific characteristics of GM and WM structural networks in subjects with clinically isolated syndrome (CIS) in comparison to patients with early relapsing-remitting multiple sclerosis (R...

The efficacy and safety of first-line disease-modifying therapies (DMT) for relapsing-remitting multiple sclerosis (RRMS) has been demonstrated in pivotal, randomized trials, but these studies do not reflect the routine care setting where treatment gaps or switches are common. The Avonex as Treatment Option for Untreated MS Patients (AXIOM) trial assessed the efficacy of newly-initiated intramu...

BACKGROUND There is no specific serum-based biomarker for the diagnosis or prognosis of relapsing-remitting multiple sclerosis (RRMS). OBJECTIVE We investigated whether levels of IgM antibodies to Glc(alpha1,4)Glc(alpha) (GAGA4) or to a panel of four glucose-based glycans could differentiate MS from other neurological diseases (OND) or predict risk of early relapse following first presentatio...
