Objectives: To investigate the risk of psoriatic arthritis (PsA) in plaque psoriasis (PsO) patients
receiving different classes of biologics.
Methods: A retrospective observational study involving consecutive bionaïve PsO patients starting biologic treatment was performed. We compared the occurrence of PsA by the class of the
biologic (tumour necrosis factor [TNF], interleukin [IL]-17, or IL-23 inhibitors) using inverse
probability of treatment weighting (IPTW) in the setting of multiple treatments to balance pretreatment covariates across cohorts and thus adjust for potential confounders. An IPTW Cox
regression model was used to estimate hazard ratios (HRs) of PsA for IL-17 and IL-23 inhibitors
versus TNF inhibitors.
Results: In total, 622 patients, 430 (62.4%) males, mean ± SD age 46.9 ± 12.9 years, were
included. They have been treated with TNF (n = 317, 50.9%), IL-17 (n = 164, 26.4%) or IL-23
inhibitors (n = 141, 22.7%) and followed for 2510 person-years (a mean of 4.1 ± 2.1 years per
person). TNF, IL-17, and IL-23 inhibitor cohorts had a total of 1569, 486, and 455 person-years
of follow-up. A total of 60 (10%) out of 622 patients on biologic therapy developed incident PsA
during the observation period: 45 (14.2%) in the TNF, 9 (5.5%) in the IL-17, and 6 (4.3%) in the
IL-23 inhibitor cohorts. After IPTW, the 3 treatment cohorts were well-balanced, and the HRs of
PsA were 0.63 (95% CI, 0.38-1.05) for IL-17 and 0.57 (95% CI, 0.34-0.96) for IL-23 compared
with the TNF treatment group.
Conclusions: The risk o
