Recipients of a Kidney Transplant
APOLLO will prospectively assess transplant outcomes in recipients of kidneys from eligible living and deceased donors at all transplant programs in the United States including Puerto Rico.
Living Kidney Donors
APOLLO will prospectively assess post-donation renal outcomes in eligible living kidney donors at all transplant programs in the United States including Puerto Rico.
- Time to death-censored renal allograft failure from the UNOS database [ Time Frame: up to 4.5 years ]Time from receipt of kidney transplant to death-censored renal allograft failure. Measured in days.
- The rate of loss of renal clearance function from clinical laboratory data [ Time Frame: up to 4.5 years ]Rate of change in the estimated glomerular filtration rate Measured in ml/min/1.73 m2.
- The rate of change in serum creatinine concentration from clinical laboratory data [ Time Frame: up to 4.5 years ]Rate of change in the reciprocal of the serum creatinine concentration. Measured as 1/serum creatinine concentration [in mg/dl].
- Time to sustained development of overt proteinuria in the outpatient setting. [ Time Frame: up to 4.5 years ]Overt proteinuria is defined as urine protein:creatinine ratio (UPCR) >500 mg/g, urine albumin:creatinine ratio (UACR) >300 mg/g, or >2+ proteinuria on urine dipstick. This outcome requires repeat documentation of proteinuria using either UPCR, UACR or dipstick test >1 month after initial detection based on clinic data
- Rate of change in kidney function and quantitative proteinuria from baseline pre-donation levels in living kidney donors (to include effects on stages of CKD) [ Time Frame: up to 4.5 years ]Rate of change (i.e., slope of change) in estimated glomerular filtration rate based on serum creatinine concentration from UNOS and clinic data
- Renal allograft failure in patients with ESRD defined based on Standardized Outcomes in Nephrology (SONG) criteria [ Time Frame: up to 4.5 years ]Renal allograft failure in patients with ESRD defined based on Standardized Outcomes in Nephrology (SONG) criteria: return to chronic renal replacement therapy (dialysis for >90 days or submission of Centers for Medicare and Medicaid Services [CMS] ESRD Medical Evidence Report [2728 Form]) or repeat kidney transplantation.36 This definition of renal allograft failure specifically excludes acute kidney injury (AKI), delayed graft function (DGF), or primary non-function (requirement of dialysis for the initial 90 days after kidney transplant or re-transplant within 90 days). The diagnoses of AKI, DGF and primary non-function will be abstracted from UNOS, clinic notes and hospital discharge summaries.
