Objective: Systemic sclerosis (SSc) is a systemic autoimmune disease affecting multiple organs, including the kidneys. There is a lack of long-term renal prognosis studies on patients with SSc. The aim of this study was to assess the risk of end-stage renal disease (ESRD) in patients with SSc. Method: We designed a prospective cohort study based on the National Health Insurance Research Database of Taiwan. Patients with SSc and a non-SSc control group were selected from 1 January 2000 to 31 December 2013. The SSc cohort and control group were matched on the propensity score in a 1:2 ratio. The primary outcome was development of ESRD. Cox proportional hazard regression was performed to assess the effects of SSc on ESRD. Results: After propensity score matching, we enrolled 2012 patients in the SSc group and 4024 patients in the control group. During a mean follow-up of 6.5 years, 86 individuals [SSc group, n = 41 (2.04%); control group, n = 45 (1.12%)] had developed ESRD. The risk of ESRD in the SSc group was approximately two times higher than that in the control group [hazard ratio (HR) = 2.12, 95% confidence interval (CI) 1.39–3.24]. Subgroup analysis revealed that the higher risk of ESRD was predominantly in males (HR = 4.14, 95% CI 1.97–8.71) and the younger population (HR = 7.09, 95% CI 2.31–21.80). Conclusion: There was a significantly higher risk of ESRD among SSc patients than among the general population, with males and younger generations being the most vulnerable groups.
