Impact of Biological Agents on Imaging and Biomarkers of Cardiovascular Disease in Patients with Psoriasis: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Trials.

Background: The effect of biologics on the risk for cardiovascular disease in patients with psoriasis is still unclear despite their widespread use.

Objective: The objective of this study was to examine the impact of licensed biological therapies on imaging and biomarkers of cardiovascular disease risk in patients with psoriasis by a systematic review and meta-analysis of placebo-controlled trials.

Methods: A comprehensive search of studies published before 1 June 2020 was performed in Medline-Ovid, EMBASE, and CENTRAL using a predefined strategy to identify relevant articles.

Results: Five studies were included for the final examination, and two studies were included in the meta-analysis. We did not find a significant reduction in aortic vascular inflammation in patients treated with adalimumab compared with those who received placebo at weeks 12-16. There was no beneficial effect on imaging biomarkers (aortic vascular inflammation or flow-mediated dilatation) of cardiovascular disease risk in patients exposed to biological therapies (adalimumab and secukinumab) compared with those exposed to placebo, except for ustekinumab showing a reduction in aortic vascular inflammation at week 12 but not at week 52 after the open-label extension period. The strongest reduction in blood-based cardiometabolic risk biomarkers was observed with adalimumab (CRP, TNF-α, IL-6, and GlycA) and phototherapy (CRP and IL-6) compared with that observed with placebo.

Conclusions: Randomized controlled trials show that ustekinumab reduces aortic vascular inflammation and that TNF-α inhibitors and phototherapy reduce CRP and IL-6. These surrogate marker findings require randomized controlled trials evaluating cardiovascular events to inform clinical practice.
