Cardiovascular Disease and Psoriasis.
Cardiovascular disease (CVD), obesity, and psoriasis are all systemic inflammatory disorders. Psoriasis is associated with an elevated risk for obesity (2) and myocardial infarction (MI), (1) as well as with multiple CV risk factors. (2) Severe psoriasis is associated with an increased risk of CV death independent of CV risk factors. (3,4)
Imaging has revealed significantly more vascular inflammation in patients with severe psoriasis (n=4; body surface area >10%) compared with age- and sex-matched controls (n=4). A nested case-control study used [[sup.18]F]-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET/CT) to detect and compare systemic inflammation in the study participants. FDG-PET/CT revealed increased inflammation in multiple aorta segments, including the coronary, hepatic, renal, and femoral arteries compared with controls. The difference remained significant after adjustment for CV risk factors (P<0.001). (5,6)
Chronic inflammation may explain why the Framingham Risk Score underestimated the 10-year incidence of CVD events in patients with psoriatic arthritis. Actual 10-year cumulative incidence of CVD events in a population-based cohort of 126 patients with psoriatic arthritis and no history of CV events was 17% (95% CI, 10-24), nearly twice as high as that predicted by the Framingham Risk Score. (7)
The coronary artery calcium score offers another way to quantify subclinical CV risk. A study measured coronary artery calcium scores in patients with moderate-to-severe psoriasis (n=129) compared with individuals with type 2 diabetes (n=129) and healthy controls (n=100). The prevalence of moderate-to-severe coronary calcification was similar for patients with psoriasis and patients with type 2 diabetes and roughly three times greater than that of controls. (8)
Do Psoriasis Therapies Reduce Risk of CVD?
Because inflammation is central to the pathophysiology of both psoriasis and CVD, investigators have evaluated whether anti-inflammatory psoriasis therapies affect the risk of CVD. Multiple observational studies report a benefit.
Analysis of nationwide databases in Denmark revealed that treatment with biologic agents (80% received tumor necrosis factor-alpha [TNF-[alpha]] inhibitors) or methotrexate was associated with lower CVD event rates over a mean follow-up of 18 months compared with patients given other antipsoriatic therapies. Adjusted hazard ratios (HRs) for the composite endpoint of death, MI, and stroke were 0.28 (95% CI, 0.12-0.64) with biologic therapies and 0.65 (95% CI, 0.42-1.00) with methotrexate. (9)
Retrospective cohort studies using claims databases have demonstrated that in patients with psoriasis, TNF-[alpha] inhibitor use was associated with:
* Significantly lower risk of MI compared with topical therapy (10)
* Significantly lower risk of major CV events (hospitalization for MI, stroke, transient ischemic attack, unstable angina) compared with methotrexate. Every additional 6 months of TNF-[alpha] inhibitor therapy was associated with an 11% reduced risk of a major CV event (P=0.02) (11)
* Significantly lower risk of major CV events compared with phototherapy (adjusted HR, 0.77; P<0.05). As in the study comparing TNF-[alpha] inhibitor therapy with methotrexate, longer use of TNF-[alpha] inhibitors was associated with increased risk reduction (12)
Crude incidence rates of atrial fibrillation and major adverse cardiovascular events (MACE) were similar with ustekinumab and TNF-[alpha] inhibitor use in patients with psoriasis or psoriatic arthritis, according to a retrospective claims data analysis. (13) However, studies examining the relationship between CV events and ustekinumab are mixed. According to a retrospective analysis of clinical trials, the rate of MACE observed with the anti-IL-12/IL-23 agents (ustekinumab and briakinumab) did not differ from that seen with placebo (P=0.12 for risk difference between anti-IL-12/23 agents and placebo). The rate of MACE observed with TNF-[alpha] inhibitors also did not differ from that reported with placebo (P=0.94 for the risk difference between anti-TNF-[alpha] agents and placebo). MACE was defined as a composite of MI, cerebrovascular accident, or CV death during the placebo-controlled phase of treatment. (14)
In a recent observational study, biologic therapy in a small number of patients with moderate-to-severe psoriasis improved coronary plaque indices. Patients with psoriasis initiating biologic therapy (n=89) and patients who elected not to receive biologic therapy (n=32) were followed prospectively, with total coronary plaque burden and plaque subcomponents measured at baseline and 1 year. Biologic therapy was associated with a small, ie, 6%, reduction in the noncalcified plaque burden (P=0.005 vs baseline), as well as decreases in fibro-fatty burden (P=0.004) and necrotic burden (P=0.03). Fibro-fatty burden increased significantly in the nonbiologic therapy group (P=0.004), but no other significant changes were noted in those patients. (15)
A growing body of evidence shows that moderate-to-severe psoriasis is a significant CV risk factor. The mechanisms underlying this relationship are not well defined, but shared inflammatory pathways between psoriasis and atherosclerosis are likely involved. (16) Multiple studies,(10-12,15) although not all, (14) demonstrate that biologic therapy for psoriasis reduces the risk of CV events. Long-term studies, ie, up to 5 years, will be required with a larger number of patients to definitely show that biologic agents can reduce the incidence of CVD in patients with moderate-to-severe psoriasis. New anti-inflammatory agents are currently being developed as treatments for CVD. (17,18)
