AB Objective Little is known about tumor necrosis factor-α (TNF-α) blockers, disease activity, and liver steatosis (hepatic steatosis; HS) in subjects with psoriatic arthritis (PsA). We prospectively evaluated changes in HS during treatment with TNF-α blockers. Methods In 48 patients with PsA who had evidence of HS before the beginning of TNF-α blocker treatment, an ultrasound followup examination was performed after a 12-month treatment period with TNF-α blockers. All subjects were stratified according to minimal disease activity (MDA) or not (n-MDA), during treatment with TNF-α blockers. Changes in grade of HS were evaluated in parallel in 42 controls with HS and without PsA. Results At baseline, no significant difference in HS score was found between PsA subjects and controls (HS scores 1.46 ± 0.65 vs 1.62 ± 0.66, respectively; p = 0.249). At 12-month followup, a worsening HS score was found in 20 (41.7%) patients with PsA and in 6 (14.3%) controls (p = 0.005). Overall, the grade of HS worsening was higher in patients with PsA (0.37 ± 0.70) than in controls (0.09 ± 0.43; p = 0.028). A significantly lower prevalence of worsening HS was found among patients with PsA with MDA, compared with n-MDA subjects (16.7% vs 66.7%, respectively; p = 0.001). Laboratory measures of liver function behaved similarly. The risk of worsening HS in patients with PsA who had MDA was similar to that in controls (HR 1.20, 95% CI 0.34–4.33, p = 0.77), and higher in patients who did not have MDA (HR 4.46, 95% CI 1.73–11.47, p = 0.001, regression analysis). Conclusion Compared with patients with MDA, those with active disease after 12-month treatment with TNF-α blockers exhibited significantly higher incidence of worsening liver steatosis.
