Objective: To assess whether early allograft function differs between pre-emptive (PKT) and previously dialyzed (DKT) live donor kidney transplant recipients.
Design: Retrospective case series
Setting: Division of Transplantation in an academic, tertiary care medical center
Patients: 24 PKT patients were selected and matched with 22 DKT patients based on age and gender, from live donor kidney transplants performed between December 2003 - December 2006. Three PKT and five DKT patients were excluded from the study due to delayed graft function, age < 18, simultaneous pancreas/kidney transplant, and absence of age/gender matched controls.
Interventions: None
Main Outcome Measures: The primary outcome was the rate of serum creatinine decline (delta creatinine) throughout the first week post-transplant. Secondary endpoints included creatinine at 1-year post-transplant, patient survival and renal allograft survival.
Results: There was a statistically significant difference in the pre-transplant creatinine between the PKT and DKT groups (6.14 mg/dl vs. 9.72 mg/dl, respectively, P < 0.0001). No other significant difference was observed between the donors or recipients from the 2 groups. The delta creatinine was similar between the two groups with most patients achieving a new baseline serum creatinine by post-transplant day 4. There is no difference in 1-year patient survival (90% PKT vs. 94% DKT, P= 0.6789), serum creatinine at 1 year (1.67 PKT vs. 1.34 DKT, P= 0.3727) or death censored 1-year graft survival (100% both groups).
Conclusions: Delta creatinine appears similar between pre-emptive and previously dialyzed live donor kidney transplant recipients throughout the first week post-transplantation. Creatinine at 1-year, 1-year patient survival and renal allograft survival are similar between the 2 groups.
