Background and Objectives: Dyslipidemia has been reported to contribute
to the psoriasis pathogenesis. Thus, evinacumab, a novel lipid-lowering drug
targeting angiopoietin-like 3, may have therapeutic potential to treat and/or
manage psoriasis. Methods and Study Design: Summary statistics were obtained from genome-wide association studies
addressing psoriasis (FinnGen Consortium; n=216,752) and serum lipid
concentrations (United Kingdom Biobank; n=403,943–440,546). Two-sample
Mendelian randomization analyses were conducted to evaluate the associations of
serum lipid concentrations and genetically mimicked effects of evinacumab,
respectively, with the risks of psoriasis and its subtypes. Results: Genetically
determined per standard deviation increase in triglyceride concentrations was
associated with increased risk of psoriasis (OR: 1.17, 95% CI: 1.03–1.32, p=0.018),
whereas that in low-density lipoprotein-cholesterol (LDL-C) was associated with
both psoriasis (OR: 1.22, 95% CI: 1.05–1.43, p=0.011) and its subtypes,
including arthropathic psoriasis (OR: 1.30, 95% CI: 1.02–1.65, p=0.032),
psoriasis vulgaris (OR: 1.87, 95% CI: 1.16–2.99, p=0.0095), and guttate
psoriasis (OR: 2.19, 95% CI: 1.17–4.07, p=0.014). Moreover, genetically
mimicked effects of evinacumab, via angiopoietin-like 3 inhibition,
significantly reduced the risk of psoriasis (OR: 0.752 per standard deviation
reduction in triglycerides, 95% CI: 0.577–0.982, p=0.036) and
arthropathic psoriasis (OR: 0.266 per standard deviation reduction in LDL-C,
95% CI: 0.0886–0.799, p=0.018). Conclusions: The genetically
mimicked effect of evinacumab has the potential to reduce the risk of psoriasis
and arthropathic psoriasis by lowering circulating triglyceride and LDL-C
concentrations, respectively. These findings suggest that evinacumab may help
prevent psoriasis and psoriatic arthritis progression in clinical practice.
