Introduction
Eric Thouvenot is mainly involved in research of biomarkers of and using proteomics. He has implemented and adapted to CSF samples a powerful immunodepletion method to remove the 20 most abundant plasma proteins from CSF, allowing in-depth characterization of CSF proteome, including low-abundant proteins secreted by CNS cells, especially using SILAC to investigate the neuronal secretome. As a Neurologist, Eric Thouvenot is involved in MS and leads the MS clinic in Nîmes University Hospital. He got several grants from pharmaceutical companies and charities (ARSEP) dedicated to clinical and physiopathological studies in MS. He coordinates a national PHRC aimed at evaluating the clinical efficacy of Vitamin D to reduce conversion to MS after a clinically isolated syndrome in 316 patients.

Background Real‐world data suggest that the early use of highly active therapies (HAT) may reduce the risk of transition to secondary progressive MS (SPMS). However, current knowledge about predictive factors of outcomes needs to be improved. The primary objective of this study was to determine factors associated with the occurrence of SPMS in pati...
Article
Background Retrospective studies did not show strong evidence of higher risk of adverse neonatal or pregnancy outcomes in women with multiple sclerosis (MS) compared to general population, but there are contradictory data on prematurity, cesarean section, and small birthweight for gestational age (SGA). Methods We compared pregnancy and birth outc...

Alzheimer’s disease and cerebral amyloid angiopathy (CAA) are often associated. Amyloid accumulation within leptomeningeal and small/median-sized cerebral blood vessels in CAA results in vessel fragility, leading to spontaneous leptomeningeal bleeding, lobar intracerebral hemorrhage (ICH) and cerebral microbleeds. CAA is also associated with non-tr...

Dimethyl fumarate (DMF) has demonstrated a favorable benefit–risk profile in patients with relapsing–remitting multiple sclerosis (RRMS). Some patients may develop lymphopenia on DMF; therefore, LymphoTEC evaluated absolute lymphocyte count (ALC) reconstitution after DMF discontinuation. LymphoTEC was a retrospective, multicenter study of patients...
Article

Background and objectives: Older studies reported an increased risk of relapse after in vitro fertilization (IVF) in women with multiple sclerosis (MS), which has not been confirmed by more recent works. All these studies had several limitations, such as small sample sizes, absence of a control population, or lack of neurologic validation of the r...
Article
Background The clinical course of myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease (MOGAD) is variable.

Background Epidemiological data reveal that 45% of persons with multiple sclerosis (PwMS) in France are more than 50 years. This population more than 50 is more susceptible to cancer, and this risk may be increased by frequent use of immunosuppressive drugs. Consequently, concerns have arisen about the potential increased risk of cancer in PwMS and...

Article
Full-text available
The immune system plays a significant role in multiple sclerosis. While MS was historically thought to be T cell-mediated, multiple pieces of evidence now support the view that B cells are essential players in multiple sclerosis pathogenic processes. High-efficacy disease-modifying therapies that target the immune system have emerged over the past...
