Abstract

Background: Secukinumab (SEC) is effective for ankylosing spondylitis (AS) and psoriatic arthritis (PsA) in randomized trials, but real-life data are lacking.

Research design and methods: Real-life, prospective observational study on 169 consecutive outpatients at baseline (T0) and at 6 (T6) and 12 months (T12) after starting SEC (39 AS, 23%; 130 PsA, 77%).

Results: Significant improvement was seen at T6 and T12 for all clinical variables, including TJC, SJC, ESR, CRP, DAPSA, ASDAS-CRP, and BASDAI, as well as in patient-reported outcomes like VAS-pain. By multivariable regression analysis, in AS patients high BASDAI at T0 correlated with diagnostic delay (R2 = 0.4; p = 0.009) and peripheral joint involvement (R2 = 0.4; p = 0.04). During follow-up, reduction of BASDAI positively correlated with high ESR (R2 = 0.65; p = 0.04). ASDAS-CRP at T0 positively correlated with high ESR (R2 = 0.34; p = 0.004). Reduction of ASDAS-CRP from T0 to T6 correlated with current smoking status (R2 = 0.42; p = 0.003). In PsA patients, reduction of DAPSA score from T0 to T12 is negatively correlated with the presence of metabolic syndrome (R2 = 0.41; p = 0.0025). SEC was well tolerated; 10 patients discontinued treatment for non-severe adverse events.

Conclusions: Secukinumab is effective and safe in patients with AS and PsA in a real-life setting.
