Abstract

Objective: The Manhattan Lupus Surveillance Program (MLSP) is a population-based registry designed to determine the prevalence of Systemic Lupus Erythematosus (SLE) in 2007 and incidence from 2007 to 2009 among Manhattan residents and characterize cases by race/ethnicity, including Asians and Hispanics for whom data are lacking.

Methods: We identified possible SLE cases from hospitals, rheumatologists, and administrative databases and defined cases using the American College of Rheumatology (ACR) classification criteria, the Systemic Lupus International Collaborating Clinics (SLICC) classification criteria, or a treating rheumatologist’s diagnosis. Rates among Manhattan residents were age-standardized, and capturerecapture (C-RC) analyses were conducted to assess case under-ascertainment.

Results: By the ACR definition, the age-standardized prevalence and incidence rates of SLE were 62.2 and 4.6 per 100,000 person-years. Rates were approximately nine times higher in women than men for prevalence (107.4 vs. 12.5) and incidence (7.9 vs. 1.0). Compared with non-Hispanic (NH) white women (64.3), prevalence was higher among NH-black (210.9), Hispanic (138.3), and NH-Asian women (91.2). Incidence rates were higher among NH-black women (15.7) compared with NH-Asian (6.6), Hispanic (6.5), and NH-white women (6.5). C-RC adjustment increased prevalence and incidence rates (75.9 and 6.0). Alternate SLE definitions without C-RC adjustment found higher agestandardized prevalence and incidence rates (SLICC: 73.8 and 6.2; rheumatologist: 72.6 and 5.0) than the ACR definition, with similar patterns by sex and race/ethnicity.

Conclusion: The MLSP confirms findings from other registries on disparities by sex and race/ethnicity, provides new estimates among Asians and Hispanics, and also provides estimates using the SLICC criteria.
