Associations with kidney transplant survival and eGFR decline in children and young adults in the United Kingdom: a retrospective cohort study
Abstract
Abstract Background Although young adulthood is associated with transplant loss, many studies do not examine eGFR decline. We aimed to establish clinical risk factors to identify where early intervention might prevent subsequent adverse transplant outcomes. Methods Retrospective cohort study using UK Renal Registry and UK Transplant Registry data, including patients aged 90 mL/min/1.73m2; − 3.55 mL/min/1.73m2/year (95% CI -4.37, − 2.72), p < 0.0001). Conclusions In conclusion, young adulthood is a key risk factor for transplant loss and eGFR decline for UK children and young adults. This study has an extended follow-up period and confirms common risk associations for graft loss and eGFR decline, including female sex, Black ethnicity and glomerular diseases. A higher initial eGFR was associated with less risk of graft loss but faster rate of eGFR decline. Identification of children at risk of faster rate of eGFR decline may enable early intervention to prolong graft survival.
