Abstract:
Objective To compare the difference of all-cause mortality between diabetic and non-diabetic transplant recipients.Methods This population cohort study included all primary kidneyonly transplant recipients with data integrity between Jan.2000 and May 2017,the deadline date of follow-up was May 2018,and median follow-up period was 5.9 (range 1.1 to 17.1) years.According to whether the recipients had diabetes,they were divided into type 2 diabetes group (DM group),and no diabetes group (non-DM group).The clinical data of the two groups including recipients and donors were collected.The all-cause mortality and difference in dead causes were analyzed.Results Mortality was higher in DM group than in non-DM group.Compared with non-DM group,the relative risk(RR) for all-cause mortality in DM group was 2.25 (95％ CI:1.23-4.12).The cumulative survival rate in non-DM group was significantly higher than that in DM group(Log Rank P =0.035).The DM group aged younger than 40 years had the highest risk (RR 4.50),but there was no significant difference between the two groups at the age of ≥40 years.Compared with living donor and cadaveric donor renal transplantation,the relative mortality risk in DM group in DCD donor renal transplantation was highest (RR 2.68).The transplantation time did not change the multiple risk of death in both groups (adjusted RR 2.13).The first cause of death in two groups was infection (50％ in DM group vs.53.3％ in non-DM group).The difference was not statistically significant.Conclusion Kidney transplant recipients with type 2 diabetes had higher all-cause mortality than in those without diabetes.Compared with non-diabetic recipients,the age ＜40 years and receiving DCD for kidneys had a greater impact on the all-cause mortality of diabetic recipients.Infection was the leading cause of death in both groups.
