Objective: To compare the levels of disability and disease activity in African-Americans and Caucasians with rheumatoid arthritis (RA) in an academic medical center practice, and to determine whether the differences are independently associated with ethnicity., Methods: Data on socioeconomic, disease related, psychological, and behavioral variables were obtained from 100 outpatients (67 Caucasians, 33 African-Americans) with RA. Functional status was assessed with the Health Assessment Questionnaire (HAQ) and Disease Activity Score (DAS-28). Chi-square and Student t tests were used to test for differences between groups. Multiple regression analysis was used to determine whether ethnicity was associated with these differences independent of other factors known to influence disease outcome., Results: African-Americans and Caucasians did not differ with respect to age, sex, disease duration, rheumatoid factor positivity, and medication compliance. African-Americans had higher scores than Caucasians for HAQ (1.5 +/- 0.8 vs 0.9 +/- 0.7; p < 0.001) and DAS-28 (5.5 +/- 1.3 vs 4.3 +/- 1.4; p < 0.001). Regression models showed that ethnicity was not independently associated with the higher HAQ and DAS-28 scores when controlled for demographic, socioeconomic, psychological, and behavioral factors. Arthritis self-efficacy approaches significance in the regression model., Conclusion: HAQ disability and RA disease activity were higher in African-Americans than Caucasians in this sample from an academic medical center practice. However, ethnicity was not independently associated with these outcomes when socioeconomic and psychological factors were taken into account. Improvement in self-efficacy has the potential to improve outcome in African-Americans with RA.

Synovial lipomatosis is a rare, synovial based disorder that typically affects a single knee. Magnetic resonance imaging and synovial biopsy established this diagnosis in a patient who presented with a 20 year history of painless swelling of the knees, wrists, and hands. Such extensive involvement, particularly of hand joints and tendon sheaths, has not been described previously. Superimposed on this chronic soft tissue joint swelling were acute knee effusions, which responded to intraarticular steroid injections. The co-occurrence with congenital short bowel syndrome may have etiological implications for this disorder of inappropriate fat deposition.
