Psoriasis treatments in the stabilization of atherosclerosis: a systematic review.

This systematic review explores the relationship between achieving minimal disease activity in psoriasis and the progression of atherosclerosis. It investigates how biologic therapies and other treatments impact atherosclerosis markers, offering insights into therapeutic strategies. A comprehensive search of PubMed, Embase, and Web of Science was conducted from January 1, 2000, to April 1, 2023, using terms such as psoriasis, psoriatic arthritis, atherosclerosis, biologic therapy, vascular stiffness, carotid intima-media thickness (CIMT), and coronary computed tomography angiography (CCTA). Eligible studies were those involving human subjects over 18, written in English, that provided quantitative atherosclerosis markers, including CIMT, CCTA, arterial pulse wave velocity (aPWV), fat attenuation index (FAI), and augmentation index (Aix). From an initial pool of 217 studies, 21 were included, grouped by treatments, including TNF-α inhibitors, IL-12/23 inhibitors, IL-17 inhibitors, DMARDs, phototherapy, and fumaric acid esters. The review found that TNF-α inhibitors significantly improved atherosclerosis markers such as CIMT, aPWV, FAI, and C-reactive protein (CRP), with reductions in these markers compared to no treatment, phototherapy, and IL-12/23 inhibitors. Additionally, IL-17 inhibitors demonstrated similar reductions in FAI compared to TNF-α inhibitors but showed a greater effect in reducing non-calcified plaque burden (12% vs. 5% for TNF-α inhibitors, p < 0.001) and also decreased CRP levels. Fumaric acid improved cholesterol metabolism (p < 0.04), and TNF-α inhibitors enhanced endothelial function (p < 0.01). Mixed results were observed when compared to DMARDs, indicating that patient-specific factors should guide treatment choices. In conclusion, TNF-α inhibitors are highly effective in reducing atherosclerosis progression in psoriasis patients, consistently improving vascular health markers like CIMT, aPWV, FAI, and CRP. IL-17 inhibitors also show significant efficacy, particularly in reducing non-calcified plaque burden, making them a valuable alternative to TNF-α inhibitors. Fumaric acid's role in cholesterol metabolism suggests its potential in combination therapies. These findings support integrating TNF-α and IL-17 inhibitors into treatment protocols for psoriasis patients with comorbid atherosclerosis, improving cardiovascular outcomes.
