Antiphospholipid syndrome (APS) is defined by thrombosis, fetal loss, and the presence of antiphospholipid antibodies, including anti-beta 2-glycoprotein-1 autoantibodies (anti-beta 2GP1) that have a direct role in the pathogenesis of thrombosis in vivo. The cellular targets of the anti-beta 2GP1autoantibody/beta 2GP1complex in vivo were studied using a laser-induced thrombosis model of APS in a live mouse and human anti-beta 2GP1 autoantibodies affinity-purified from APS patients. Cell binding of fluorescently labeled beta 2GP1 and anti-beta 2GP1 autoantibodies revealed their colocalization on the platelet thrombus but not the endothelium. Anti-beta 2GP1 autoantibodies enhanced platelet activation, monitored by calcium mobilization, and endothelial activation, …

BACKGROUND: This study aimed to assess long-term safety and developmental data on juvenile idiopathic arthritis (JIA) patients treated in routine clinical practice with celecoxib or nonselective nonsteroidal anti-inflammatory drugs (nsNSAIDs). METHODS: Children aged >/=2 to-negative polyarthritis, persistent or extended oligoarthritis, or systemic arthritis were enrolled into this prospective, observational, multicenter standard-of-care registry. Eligible patients were newly or recently prescribed (

OBJECTIVE: To compare the performance characteristics of cell-bound complement (C4d) activation products (CBCAPS) on erythrocyte (EC4d) and B cells (BC4d) with antibodies to double-stranded DNA (anti-dsDNA) and complement C3 and C4 in systemic lupus erythematosus (SLE). METHODS: The study enrolled 794 subjects consisting of 304 SLE and a control group consisting of 285 patients with other rheumatic diseases and 205 normal individuals. Anti-dsDNA and other autoantibodies were measured using solid-phase immunoassays while EC4d and BC4d were determined using flow cytometry. Complement proteins were determined using immunoturbidimetry. Disease activity in SLE was determined using a non-serological Systemic Lupus Erythematosus Disease Activity …

OBJECTIVE: To compare the incidence rates of malignancy among patients with psoriatic arthritis (PsA) and patients with rheumatoid arthritis (RA) in the Consortium of Rheumatology Researchers of North America (CORRONA) registry. METHODS: We analyzed 2,970 patients with PsA (7,133 patient-years of followup) and 19,260 patients with RA (53,864 patient-years of followup). Using a standardized adjudication process, we identified 40 confirmed malignancies in the patients with PsA and 307 confirmed malignancies in those with RA. Incidence rates were calculated per 100 patient-years. Incidence rate ratios were estimated, with adjustment for age, sex, disease duration, body mass index, disease activity, year of …

Objective. To compare the efficacy and safety of intravenous (IV) abatacept, a selective T cell costimulation modulator, versus placebo for the treatment of active class III or IV lupus nephritis, when used on a background of mycophenolate mofetil and glucocorticoids. Methods. This was a 12-month, randomized, phase II/III, multicenter, international, double-blind study. A total of 298 patients were treated in 1 of 3 IV treatment arms: placebo, abatacept at the standard weight-tiered dose (approximating 10 mg/kg), or abatacept at 30 mg/kg for 3 months, followed by the standard weight-tiered dose (abatacept 30/10). The primary end point, time to confirmed complete …

Introduction: Type I interferons (IFNs) are implicated in the pathogenesis of systemic sclerosis (SSc). MEDI-546 is an investigational human monoclonal antibody directed against the type I IFN receptor. This Phase 1 study evaluated the safety/tolerability, pharmacokinetics (PK), immunogenicity, and pharmacodynamics (PD) of single and multiple intravenous doses of MEDI-546 in adults with SSc. Methods: Subjects (>= 18 years) with SSc were enrolled in an open-label, dose-escalation study to receive single (0.1, 0.3, 1.0, 3.0, 10.0, or 20.0 mg/kg), or 4 weekly intravenous doses (0.3, 1.0, or 5.0 mg/kg/week) of MEDI-546. Subjects were followed for 12 weeks. Safety assessments included …

OBJECTIVE: To assess the efficacy and safety of rilonacept, an interleukin-1 inhibitor, in a randomized, double-blind, placebo-controlled trial. METHODS: An initial 4-week double-blind placebo phase was incorporated into a 24-week randomized multicenter design, followed by an open-label phase. Seventy-one children who had active arthritis in >/=2 joints were randomized (1:1) to the 2 arms of the study. Patients in the rilonacept arm received rilonacept (loading dose 4.4 mg/kg followed by 2.2 mg/kg weekly, subcutaneously) beginning on day 0. Patients in the placebo arm received placebo for 4 weeks followed by a loading dose of rilonacept at week 4 followed by …
