ABSTRACT
Background/Objectives: Psoriasis is a chronic inflammatory disease that significantly impacts physical and emotional health. Statins, primarily used as lipid-lowering drugs, have also demonstrated anti-inflammatory effects. While some studies suggest that statins may improve psoriasis symptoms, the findings have been inconsistent. This study aims to investigate the association between prior statin use and the onset of psoriasis in a Korean population, focusing on individuals with dyslipidemia to minimize confounding factors. Methods: Using the Korean Health Insurance database (2002-2019), a nationwide nested case-control study was conducted, enrolling 8285 participants with psoriasis and 33,140 controls, matched 1:4 for sex, age, residence, and income through propensity scoring. Results: Adjusted odds ratios revealed significantly lower risks of psoriasis among short-term statin users (OR = 0.70, 95% CI = 0.66-0.74) and long-term users (OR = 0.77, 95% CI = 0.73-0.82) than in nonusers. This trend was consistent for both lipophilic and hydrophilic statins, and across subgroup analyses. Conclusions: These findings suggest that statins may reduce the incidence of psoriasis. However, further research is needed to assess their effects on psoriasis progression and severity.
