- Objective To study long-term work disability before and after tumour necrosis factor (TNF)-antagonist therapy in patients with psoriatic arthritis (PsA). Using the population-based South Swedish Arthritis Treatment Group Register, we identified 191 patients with PsA (median age 43years, range 18-58years, 54% men), who between January 2003 and December 2007 started treatment with adalimumab, etanercept or infliximab. We linked data to the Swedish Social Insurance Agency and calculated the proportion of work disability in 30-day intervals from 12months before the start of treatment until 3years after. For each patient with PsA we randomly selected four matched reference subjects from the general population. At treatment initiation 67% of the patients with PsA were work disabledthat is, either on sick leave (41.5%) or receiving a disability pension (25.3%). Patients sustaining treatment were, on average, work disabled 12.5days a month at treatment initiation declining to 10.6days a month after 3years of treatment. Patients for whom the first treatment course failed were work disabled 16.5days at treatment start decreasing to 15.6days after 3years. The background population were 2.5days and 3.0days off work each month, respectively. Regression modelling identified prior work disability status, anti-TNF treatment failure, higher age, female gender and longer disease duration as significant predictors of working disability. There was a decline in net work disability after initiation of anti-TNF treatment in patients with PsA. Patients withdrawing from treatment had a 50% increased risk of being work disabled. Prior work disability, higher age, female gender and longer disease duration were also associated with long-term work disability.

- Objective: To identify predictors of sick leave and disability pension in patients with early rheumatoid arthritis (RA). Methods: Individuals aged 19-59 years diagnosed with early RA (=12 months symptom duration) were identified in the Swedish Rheumatology Quality Register (1999-2007; n=3029). We retrieved days of sick leave and disability pension from the Swedish Social Insurance Agency and baseline predictors of total work days lost during 3 years after RA diagnosis were investigated using linear regression. Due to effect modification by baseline work ability (defined as work days lost the month before diagnosis), analyses were stratified into three categories: full=0 work days lost the month before diagnosis; partial=1-29 work days lost; and none=30 work days lost. Results: 71% of patients with full baseline work ability still had full work ability after 3 years compared with 36% (p<0.001) and 18% (p<0.001) of those with partial and no work ability at baseline, respectively. Elevated baseline levels of HAQ and DAS28, higher age, lower education level and unemployment were associated with more work days lost during 3 years in all strata of baseline work ability (all p<0.05). In a separate analysis, more objective variables (ESR, CRP and swollen joints) were not. Generally, the largest regression coefficients were seen for patients with partial baseline work ability. Conclusions: Work ability at RA diagnosis was the most important predictor of 3-year sick leave and disability pension. Taking this into account, HAQ, DAS28, age and education level were also significant predictors, whereas ESR and CRP were not.
