Statin use and the risk of chronic kidney disease in patients with psoriasis: A nationwide cohort study in Taiwan.
Ontology highlight
ABSTRACT: BACKGROUND:Psoriasis is associated with hyperlipidemia. Few studies have examined the association among psoriasis, hyperlipidemia, and chronic kidney disease (CKD). It remains a topic of debate whether statin treatment for hyperlipidemia prevents the development of CKD in patients with psoriasis. OBJECTIVE:We investigated whether there is an association among psoriasis, hyperlipidemia and CKD. If so, we asked whether statin treatment for hyperlipidemia reduces the risk of CKD in patients with psoriasis. METHODS:A Taiwan nationwide population-based cohort study between 1997 and 2010 included 2,912 patients with psoriasis and 8,736 matched patients without psoriasis (1:3 propensity score matched according to age, sex, and region); 104,609 patients without psoriasis but with hyperlipidemia and 104,609 matched patients without psoriasis or hyperlipidemia (1:1). The hazard ratios, relative risks, and 95% confidence intervals were calculated using Cox proportional hazards model. RESULTS:Psoriasis significantly increased the risk of CKD (adjusted hazard ratio 2.48, 95% confidence interval 1.81-3.40), and so did hyperlipidemia (adjusted hazard ratio 2.93, 95% confidence interval 2.79-3.08). Compared to treatment without statins, statin treatment for hyperlipidemia reduced the risk of CKD in patients with psoriasis (adjusted relative risk 0.58, 95% confidence interval 0.55-0.62). CONCLUSION:As well as hyperlipidemia, psoriasis significantly increased the risk of CKD. Statin treatment for hyperlipidemia reduced the risk of CKD in patients with psoriasis.
