OBJECTIVE: To assess the effect of tumor necrosis factor inhibitors (TNFi) on subclinical cardiovascular disease in patients with psoriatic disease. METHODS: We performed a 2-stage study. In stage 1, carotid total plaque area was assessed in patients with psoriasis or psoriatic arthritis (PsA) (n = 319) by ultrasound at baseline and after 2-3 years. The annual progression rate of atherosclerosis was the outcome of interest. In stage 2, PsA patients receiving TNFi (n = 21) and age- and sex-matched PsA patients not receiving any biologic agent (n = 13) underwent 18 F-fluorodeoxyglucose-positron emission tomography/computed tomography at baseline and 1 year to assess vascular inflammation, measured as target-to-background ratio (TBR). In both stages, multivariable regression analyses adjusted for cardiovascular risk factors and use of statins were performed. RESULTS: In stage 1, men had significantly higher atherosclerosis progression than women (P < 0.001). TNFi was associated with reduced atherosclerosis progression in men after controlling for cardiovascular risk and use of statins (adjusted β = -2.20 [95% confidence interval -3.41, -1.00], P < 0.001). There was no association between TNFi and atherosclerosis progression in women (P = 0.74). In stage 2, patients receiving TNFi had reduced TBR at 1 year (P = 0.03). Those not receiving TNFi had no significant change in TBR (P = 0.32). The improvement in aortic vascular inflammation in the TNFi group was independent of cardiovascular risk factors (adjusted β = -0.41 [95% confidence interval -0.74, -0.08], P = 0.02). CONCLUSION: Our findings indicate that TNFi treatment is associated with reduced progression of carotid plaques in men and improvement in vascular inflammation in both men and women with psoriatic disease.
