Session Title: Sjögren's Syndrome - Poster II: Clinical Science

Session Type: ACR Poster Session C

Session Time: 9:00AM-11:00AM

Background/Purpose: To study long-term work disability (WD) and possible predictors in newly diagnosed patients with primary Sjögren’s syndrome (pSS).

Methods: 51 pSS patients (mean age 46 years, range 18-61 years, 50 females) diagnosed with pSS between January 2001 and December 2012 were included in the study. For each patient we randomly selected four reference subjects from the general population matched for age, sex and area of residence as controls. We linked data to the Swedish Social Insurance Agency and calculated the proportion as well as net days of WD in 30-day intervals from 12 months before pSS diagnosis until 24 months after.

Results: WD, consisting of sick leave (SL) and disability pension (DP), was increased in pSS patients in comparison to general population controls (GPC) (Fig 1A and B). Two years after pSS diagnosis the relative risk for overall WD was 2.10 (95% CI 1.34 to 3.30) in comparison with the general population. At diagnosis, 26% of patients were work disabled increasing to 37% and 41%, 12 and 24 months after diagnosis, respectively (p<0.05 and p<0.05 vs. baseline). Prior work disability status at pSS diagnosis (OR=15.4, 95% CI 2.9 to 81.9; p=0.001), concomitant fibromyalgia (OR=10.5, 95% CI 2.0 to 56.0; p=0.006), and each additional year of age (OR=1.1, 95% CI 1.0 to 1.2; p=0.009) were found to be associated with WD 24 months after diagnosis.

Conclusion: pSS patients showed an increased WD in comparison with the general population. Furthermore, WD in pSS patients increased significantly during the first two years after diagnosis, initially due to an increase in SL and subsequently to an increase in patients receiving a DP. WD at diagnosis, concomitant fibromyalgia and increasing age were associated with long-term work disability. Figure 1A.
