Insights
This study found no significant differences in major cardiovascular events (CVEs) among patients with psoriasis treated with ustekinumab, etanercept, adalimumab, or methotrexate. Further research is needed to confirm these findings with longer follow-up periods.
Area of Science:
- Dermatology
- Cardiology
- Pharmacology
Background:
- The cardiovascular safety of biologic therapies for psoriasis remains unclear.
- Psoriasis is associated with an increased risk of cardiovascular disease.
Purpose of the Study:
- To compare the risk of major cardiovascular events (CVEs) in patients with chronic plaque psoriasis treated with adalimumab, etanercept, or ustekinumab.
- To evaluate the comparative risk of CVEs between different biologic therapies and methotrexate.
Main Methods:
- A large prospective cohort study was conducted using the British Association of Dermatologists Biologics and Immunomodulators Register.
- Comparative risk of major CVEs was analyzed using propensity score overlap weights to balance covariates.
- Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated for ustekinumab vs. tumor necrosis factor-α inhibitors (TNFi), and other comparisons including methotrexate.
Main Results:
- 5468 biologic-naïve patients were included in the main analysis (951 ustekinumab, 1313 etanercept, 3204 adalimumab).
- Secondary analyses included 2189 patients receiving methotrexate.
- No significant differences in the risk of major CVEs were observed between ustekinumab, TNFi (adalimumab, etanercept), and methotrexate (adjusted HRs ranging from 0.81 to 1.05).
Conclusions:
- This study found no significant differences in the risk of major cardiovascular events (CVEs) among patients with chronic plaque psoriasis treated with adalimumab, etanercept, ustekinumab, or methotrexate.
- Longer-term follow-up studies are necessary to further investigate the potential cardiovascular effects of these biologic therapies.
Background:
The cardiovascular safety profile of biologic therapies used for psoriasis is unclear.
Objectives:
To compare the risk of major cardiovascular events (CVEs; acute coronary syndrome, unstable angina, myocardial infarction and stroke) in patients with chronic plaque psoriasis treated with adalimumab, etanercept or ustekinumab in a large prospective cohort.
Methods:
Prospective cohort study examining the comparative risk of major CVEs was conducted using the British Association of Dermatologists Biologics and Immunomodulators Register. The main analysis compared adults with chronic plaque psoriasis receiving ustekinumab with tumour necrosis-α inhibitors (TNFi: etanercept and adalimumab), whilst the secondary analyses compared ustekinumab, etanercept or methotrexate against adalimumab. Hazard ratios (HRs) with 95% confidence intervals (CIs) were calculated using overlap weights by propensity score to balance baseline covariates among comparison groups.
Results:
We included 5468 biologic-naïve patients subsequently exposed (951 ustekinumab; 1313 etanercept; and 3204 adalimumab) in the main analysis. The secondary analyses also included 2189 patients receiving methotrexate. The median (p25-p75) follow-up times for patients using ustekinumab, TNFi, adalimumab, etanercept and methotrexate were as follows: 2.01 (1.16-3.21), 1.93 (1.05-3.34), 1.94 (1.09-3.32), 1.92 (0.93-3.45) and 1.43 (0.84-2.53) years, respectively. Ustekinumab, TNFi, adalimumab, etanercept and methotrexate groups had 7, 29, 23, 6 and 9 patients experiencing major CVEs, respectively. No differences in the risk of major CVEs were observed between biologic therapies [adjusted HR for ustekinumab vs. TNFi: 0.96 (95% CI 0.41-2.22); ustekinumab vs. adalimumab: 0.81 (0.30-2.17); etanercept vs. adalimumab: 0.81 (0.28-2.30)] and methotrexate against adalimumab [1.05 (0.34-3.28)].
Conclusions:
In this large prospective cohort study, we found no significant differences in the risk of major CVEs between three different biologic therapies and methotrexate. Additional studies, with longer term follow-up, are needed to investigate the potential effects of biologic therapies on incidence of major CVEs.
