Objectives: Patients with psoriasis may have a higher risk of developing chronic kidney (CKD) and end-stage renal disease (ESRD) compared with general population. This systematic review and meta-analysis aimed to comprehensively investigate this association by reviewing all available evidence. Methods: A systematic review was performed using MEDLINE and EMBASE database from inception to January 2018 to identify all cohort studies that compared the risk of incident CKD and/or ESRD in patients with psoriasis versus individuals without psoriasis. Pooled risk ratio and 95% confidence interval were calculated using random-effect, generic inverse variance method. Results: A total of four retrospective cohort studies with 199,808 patients with psoriasis were included. The risk of incident CKD and ESRD was significantly increased among patients with psoriasis with the pooled risk ratio of 1.34 (95% CI, 1.14–1.57) and 1.29 (95% CI, 1.05–1.60), respectively. Conclusion: A significantly increased risk of incident CKD and ESRD among patients with psoriasis compared with individuals without psoriasis was demonstrated in this study.
