Antiphospholipid syndrome (APS), induces endothelial dysfunction, oxidative stress and systemic inflammation that may be mediated by TNFα. Thus, we investigated the possible protective effect of the anti-TNFα antibody infliximab (5μg/g) on endothelial function in a mouse APS model (induced by injection of purified human anti-β2GP1-IgG). Seven days after(More)
Numerous autoimmune-inflammatory rheumatic diseases have been associated with accelerated atherosclerosis or other types of vasculopathy leading to an increase in cardiovascular disease incidence. In addition to traditional cardiovascular risk factors, endothelial dysfunction is an important early event in the pathogenesis of atherosclerosis, contributing(More)
INTRODUCTION Venous thromboembolism and dehydration are frequent conditions in elderly. The objective of this study was to assess the prevalence of dehydration in patients aged over 70 years suspected of deep vein thrombosis (DVT). METHODS This is a prospective observational study that included patients aged over 70 years and suspected of deep vein(More)
PURPOSE More than one million patients received an oral anticoagulant treatment in France. This medication is the first aetiology of iatrogenic events. Recently, direct oral anticoagulant (DOA) provided efficacy and safety in the treatment of atrial fibrillation and venous thromboembolic events. Given the growing increase in the prescription of these(More)
OBJECTIVE To assess the role of Toll-like receptors (TLRs) in antiphospholipid antibody (aPL)-mediated vascular abnormalities in patients with primary arterial antiphospholipid syndrome (APS). METHODS Forty-eight subjects participated in the study. Arterial function and structure and TLR pathway activation were determined in patients with primary arterial(More)
BACKGROUND Initial morphological and functional markers of systemic sclerosis (SSc) are evidenced in microvascular structural damage. However, nailfold videocapillaroscopy (NVC) explores only morphological abnormalities. Sidestream Dark Field (SDF) imaging of sublingual microcirculation enables assessment of both morphological and functional capillary(More)
Bradykinin-mediated angioedema (AE) is a rare side effect of some medications, including angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB). In France, side-effects to treatments are reported to the national pharmacovigilance database. The national MedDRA database was searched using the term “angioedema”. Patients were(More)
