INTRODUCTION We compared 2 anti-citrullinated protein antibody (ACPA) assays using a routine patient cohort. METHODS Two-hundred ninety-five sera were collected from patients for whom ACPA was ordered and tested for ACPA by QUANTA Lite® CCP 3 (INOVA Diagnostics, Inc., San Diego) and EliA® CCP (CCP, Phadia, Germany). Rheumatoid factor (RF) was determined(More)
OBJECTIVE To evaluate the tolerability, effectiveness and utilization of tocilizumab for the treatment of RA in a usual care setting. METHODS ROUTINE was a prospective, non-interventional, observational 52-week study performed at 174 sites throughout Germany. RA patients were selected and treated according to label. Study objectives included the targeted(More)
INTRODUCTION Anti-centromere antibodies (ACA) are useful biomarkers in the diagnosis of systemic sclerosis (SSc). ACA are found in 20 to 40% of SSc patients and, albeit with lower prevalence, in patients with other systemic autoimmune rheumatic diseases. Historically, ACA were detected by indirect immunofluorescence (IIF) on HEp-2 cells and confirmed by(More)
Anti-ribosomal P (Rib-P) autoantibodies have been demonstrated to be a specific diagnostic marker for systemic lupus erythematosus (SLE). The aim of this study was to evaluate the prevalence of anti-Rib-P (C22) antibodies in patients with SLE drawn from international, multi-center clinics. Sera collected from patients with SLE (n = 333) and various controls(More)
BACKGROUND We evaluated the analytical and clinical performances of a novel, automated chemiluminescent immunoassay in comparison with several anti-citrullinated protein antibody (ACPA) assays (2nd and 3rd generations) based on various platforms and technologies. METHODS Samples from rheumatoid arthritis (RA) patients (n=141) and controls (n=153) were(More)
