Abstract

Patients with end-stage renal disease (ESRD) on chronic hemodialysis (HD) experience chronic inflammation and immune dysregulation; whether these affect the development of chronic inflammatory disease such as psoriasis is unknown. We aimed to investigate the impact of ESRD on the development of psoriasis. We performed a retrospective cohort study using records between 1999 and 2013 from Taiwan's National Health Insurance Research Database. Among 74 916 patients with ESRD on chronic HD and the control group comprising 74 916 sex and age group-matched patients, 165 and 81 incident psoriasis developed after a mean follow up of 2.4 and 2.9 years, respectively. The incidence rates of psoriasis in HD patients and the control group were 91.7 and 37.1 per 100 000 person-years, respectively (difference between groups, P < 0.001). HD patients had a shorter time to psoriasis diagnosis than the control group (P < 0.05). Cox proportional hazard adjustment showed the hazard ratio (HR) for psoriasis in HD patients as 2.09 (95% confidence interval [CI], 1.49-2.94; P < 0.001) than that of the control group. Younger HD patients had relatively higher risk of psoriatic development (age <60 years; adjusted HR, 3.68; 95% CI, 1.93-7.02; P < 0.001). The relative risk of psoriatic arthritis was not increased in HD patients compared with the control group. In conclusion, patients with ESRD on chronic HD had a greater risk of developing psoriasis. Physicians should be aware of the predisposition to psoriasis in patients with ESRD on chronic HD.
