Incidence and Prevalence of pSS in New York County

Arthritis Care Res; ePub 2018 Jul 25; Izmirly, et al

Data from the Manhattan Lupus Surveillance Program (MLSP) revealed disparities in primary Sjögren’s Syndrome (pSS) incidence and prevalence by sex among Manhattan residents and differences in pSS incidence by race/ethnicity among women. This according to a recent study that also found that these data provided epidemiologic estimates for the major racial/ethnic populations in the US. MLSP cases were identified from hospitals, rheumatologists, and population databases. 3 case definitions were used for pSS: physician diagnosis, rheumatologist diagnosis, and modified pSS criteria. Rates among Manhattan residents were age‐adjusted, and capture‐recapture analyses were conducted to assess case under‐ascertainment. Researchers found:

  • By physician diagnosis, age‐adjusted overall incidence and prevalence rates of pSS among adult Manhattan residents were 3.5 and 13.1 per 100,000 person‐years.
  • Capture‐recapture adjustment increased incidence and prevalence rates (4.1 and 14.2).
  • Based on physician diagnosis, incidence and prevalence rates were approximately 6 times higher among women than men.
  • Incidence of pSS was statistically higher among non‐Latina Asian (10.5) and non‐Latina white women (6.2) compared with Latina women (3.2).
  • Incidence was also higher among non‐Latina Asian women compared with non‐Latina black women (3.3).
