Does modulation of inflammation by treatment with biologic agents affect the progression of coronary artery disease in patients with severe psoriasis?
In this clinical study, at the end of 13 months’ follow-up, reduced coronary artery disease progression was observed in patients with severe psoriasis who were treated with biologic agents compared with controls. Repeated coronary computed tomographic angiography showed significant reduced progression of coronary plaque severity, and reduced progression of calcium scores.
In addition to disease control, treatment with anti-inflammatory biologic agents may reduce coronary artery disease progression in patients with severe psoriasis.
Inflammatory pathways of psoriasis share similarities with the mechanisms identified in atherosclerosis, and the association between psoriasis and cardiovascular disease due to accelerated coronary artery disease is well established. The effect of anti-inflammatory drugs on the development of coronary atherosclerosis remains essentially unknown.
To investigate the association of biological therapy with changes in coronary artery disease progression, measured by repeated coronary computed tomography (CT).
Design, Setting, and Participants
This single-center prospective, controlled, observer-blinded clinical study at a tertiary dermatology university hospital clinic enrolled patients with severe psoriasis initiating biological therapy and matched controls not receiving systemic therapy from April 11, 2011, through June 30, 2014.
Biological therapy approved for psoriasis (adalimumab, etanercept, infliximab, ustekinumab) with the possibility to switch between treatments to ensure tight control of inflammation.
Main Outcomes and Measures
Patients underwent noncontrast coronary artery calcium (CAC) CT and contrast-enhanced coronary CT angiography at baseline and after 13 months of follow-up. Changes in CAC score, number of coronary plaques, severity of narrowing, composition, and vessel wall volume were measured.
There were 28 treated patients (mean [SD] age, 49.2 [10.2] years; 71% men; mean [SD] Psoriasis Area Severity Index [PASI], 15.4 [4.3]) and 28 controls (mean [SD] age, 52.8 [10.6] years; 71% men; mean [SD] PASI, 12.4 [3.9]). The CAC scores remained stable in the intervention group (mean [SD] yearly CAC change, −16 ; P = .15) and progressed in the control group (14 ; P = .02) (intervention vs controls: P = .02). The number of segments with luminal abnormalities remained unchanged in both groups. The severity of luminal narrowing in the diseased segments was unchanged in the intervention group (Wilcoxon W = 76, n = 483, P = .39) but increased at follow-up in the control group (Wilcoxon W = 281, n = 414, P = .02). Automated vessel wall volume index remained unchanged from baseline to follow-up in the intervention group (mean [SD] baseline, 7.1 [1.5], follow-up, 7.1 [1.7]; P = .91), while controls demonstrated statistically nonsignificant progression (baseline, 8.3 [1.6], follow-up, 8.9 [2.2]; P = .06).
Conclusions and Relevance
Clinically effective treatment with biologic agents was associated with reduced coronary artery disease progression in patients with severe psoriasis. These findings support a beneficial effect of biologic anti-inflammatory agents in preventing cardiovascular disease progression in addition to disease control in inflammatory diseases.
