Radiographic severity of rheumatoid arthritis in African Americans: results from a multicenter observational study.

Objective: To describe radiographic changes in African Americans with rheumatoid arthritis (RA) from the Consortium for the Longitudinal Evaluations of African Americans with Early Rheumatoid Arthritis (CLEAR) Registry, a multicenter observational study.

Methods: Self-declared African American patients were enrolled in CLEAR I, a longitudinal cohort of early RA (disease duration of <2 years) from 2000 to 2005, or in CLEAR II, a cross-sectional cohort (any disease duration) from 2006 to the present. Demographic and clinical data were obtained, and sets of hand/wrist and foot radiographs were scored using the modified Sharp/van der Heijde scoring system.

Association of IL4R single-nucleotide polymorphisms with rheumatoid nodules in African Americans with rheumatoid arthritis.

Introduction: To determine whether IL4R single-nucleotide polymorphisms (SNPs) rs1805010 (I50V) and rs1801275 (Q551R), which have been associated with disease severity in rheumatoid arthritis (RA) patients of European ancestry, relate to the presence of rheumatoid nodules and radiographic erosions in African Americans.

Methods: Two IL4R SNPs, rs1805010 and rs1801275, were genotyped in 749 patients from the Consortium for Longitudinal Evaluation of African-Americans with Early Rheumatoid Arthritis (CLEAR) registries. End points were rheumatoid nodules defined as present either by physical examination or by chest radiography and radiographic erosions (radiographs of hands/wrists and feet were scored using the modified Sharp/van der Heijde system).

Are glucocorticoids DMARDs?

Disease modifying antirheumatic drugs (DMARDs) are drugs used in rheumatoid arthritis (RA) to control the disease and to limit joint damage and improve long-term outcome. The last decade evidence has accumulated that suggests that low dosages of glucocorticoids are indeed able to control the disease and limit the destruction. This role is especially present in early disease and in combination with other drugs.

Followup radiographic data on patients with rheumatoid arthritis who participated in a two-year trial of prednisone therapy or placebo.

Objective: In a previous clinical trial of patients with early rheumatoid arthritis (RA), it was determined that patients who received 10 mg of prednisone per day for 2 years had less radiographic joint damage compared with those who received placebo. Our goal was to investigate whether this beneficial effect persisted after the end of the trial.

Methods: A blinded assessment of radiographic joint damage was performed approximately 3 years after the end of the original 2-year study.

The clinical effect of glucocorticoids in patients with rheumatoid arthritis may be masked by decreased use of additional therapies.

Objective: Our previous analysis of patients with early active rheumatoid arthritis (RA) treated with prednisone or placebo revealed the following discrepancy: although a significant retardation of joint damage was observed in the prednisone group compared with the placebo group, no differences in clinical variables between the 2 groups were observed, due to greater use of additional therapy in the placebo group. We sought to investigate whether this discrepancy would extend to variables of well-being.

Methods: We conducted a double-blind, randomized, placebo-controlled clinical trial of prednisone (10 mg) in patients with RA; the duration of the study was 2 years.
