Systemic lupus erythematosus (SLE) is a severe and incurable autoimmune disease characterized by chronic activation of plasmacytoid dendritic cells (pDCs) and production of autoantibodies against nuclear self-antigens by hyperreactive B cells. Neutrophils are also implicated in disease pathogenesis; however, the mechanisms involved are unknown. Here, we(More)
OBJECTIVES To determine the causes and predictors of mortality in systemic sclerosis (SSc). METHODS Patients with SSc (n=5860) fulfilling the American College of Rheumatology criteria and prospectively followed in the EULAR Scleroderma Trials and Research (EUSTAR) cohort were analysed. EUSTAR centres completed a structured questionnaire on cause of death(More)
Systemic sclerosis (SSc) is an orphan, complex, inflammatory disease affecting the immune system and connective tissue. SSc stands out as a severely incapacitating and life-threatening inflammatory rheumatic disease, with a largely unknown pathogenesis. We have designed a two-stage genome-wide association study of SSc using case-control samples from France,(More)
Psoriasis is a common T-cell-mediated skin disease with 2-3% prevalence worldwide. Psoriasis is considered to be an autoimmune disease, but the precise nature of the autoantigens triggering T-cell activation remains poorly understood. Here we find that two-thirds of patients with moderate-to-severe plaque psoriasis harbour CD4(+) and/or CD8(+) T cells(More)
In systemic lupus erythematosus (SLE) nailfold capillaroscopy (NC) studies have described many different nonspecific patterns. We decided to evaluate NC changes in 44 SLE patients, comparing them with the main clinical, demographic and laboratory parameters, thus to define the real role for NC and its abnormalities in the management of this disease. Fifteen(More)
Systemic sclerosis (SSc) is a connective tissue disease characterized by vascular damage and interstizial fibrosis of many organs. Our interest was focused on the evaluation of cardiac autonomic function by measurements of heart rate variability (HRV) and microvascular damage detected by nailfold capillaroscopy (NC) in SSc patients. We examined 25(More)
OBJECTIVES An Italian multicentre study was promoted in order to assess the accuracy of four anti-double-stranded DNA (dsDNA) antibody assays for SLE diagnosis and monitoring. METHODS Two hundred and twenty-three patients with established SLE according to ACR classification criteria were enrolled from 9 centres. They included 59 patients at first(More)
OBJECTIVES To asses risk factors for a first thrombotic event in antiphospholipid antibody (aPL) positive carriers and evaluate the efficacy of prophylactic treatments. METHODS Recruitment criteria were age 18-65 years, no history of thrombosis, positivity for lupus anticoagulant and/or IgG/IgM anticardiolipin antibody (aCL) on > or =2 occasions at least(More)
OBJECTIVE Pulmonary arterial hypertension (PAH) has emerged as a leading cause of death in systemic sclerosis (SSc). The genetic basis of PAH has been unraveled in recent years, with a major role played by transforming growth factor β receptors; however, some other candidate genes have also been advocated, including potassium voltage-gated channel,(More)
OBJECTIVE To identify a core set of preliminary items considered as important for the very early diagnosis of systemic sclerosis (SSc). METHODS A list of items provided by European League Against Rheumatism (EULAR) Scleroderma Trial and Research(EUSTAR) centres were subjected to a Delphi exercise among 110 experts in the field of SSc. In round 1, experts(More)
