Trends of kidney transplantation from the 2020 annual report on kidney disease in Taiwan

Abstract

Background: Renal transplantation (RTX) is the treatment of choice for end-stage kidney disease (ESKD). Taiwan has the highest incidence and prevalence of ESKD in this world. This is the first study to illustrate the national registry database of RTX. Methods: All patients who received RTX in Taiwan between 2010 and 2018 were enrolled in this study. Demographic data and comorbidities were obtained from the National Health Insurance Research Database and Transplantation Society of Taiwan. Graft and patient survival rates were also analyzed. Results: Men were more likely to receive RTX. During the observation periods, > 30% of the recipients were relatively young (20–44 years). The percentage of preemptive RTX (p = 0.014) and living RTX (p = 0.022) increased annually with statistical significance (linear regression model). Recently, recipients had more cardiovascular disease (p = 0.014), diabetes mellitus (p = 0.097), and hypertension (p = 0.021). The mean duration of graft survival increased yearly (p = 0.001). The proportion of patients surviving till age of ≧65 years increased significantly with time (2.2% in 2010, 33.1% in 2018) (p < 0.0001). Younger recipients (<44 years) had significantly better survival than the elderly (≧65 years). Patients with diabetes were more likely to have worse graft and patient survival rates. Recipients enrolled in pre-ESRD care program had better graft and patient survival rates than those not enrolled in these care program. Conclusion: The proportion of preemptive and livingdonor RTX increased but was still low. Despite increased number of commodities in recipients, graft and patient survival have increased recently. Enrolling patients with CKD in pre-ESRD care program was associated with better graft and patient survival.
