Pretransplantation Systolic Blood Pressure and the Risk of Delayed Graft Function in Young Living-Related Renal Allograft Recipients

Delayed graft function (DGF) is associated with decreased long-term renal allograft survival, however, the entire mechanism of action of DGF has not yet been established. The goal of this study was to determine possible risk factors for DGF in young living-related renal allograft recipients. We retrospectively analyzed the outcome of 142 renal transplant recipients (115 men and 27 women; mean age, 29.7 ± 9.43 years; 114 living-related donors and 28 cadaveric donors). Data recorded for each patient and donor included gender, age at transplantation, duration of pretransplantation dialysis (recipients only), body mass index, number of human leucocyte antigen mismatches, panel-reactive antibodies, donor creatinine clearance, body weight, systolic and diastolic blood pressure levels, lipid profile, and biochemical parameters. Having obtained the transplant from a cadaveric donor (P < .000, odds ratio [OR] = 17.556, confidence interval [CI] = 5.961–51.743) and a pretransplantation systolic blood pressure level in the recipient of <120 mm Hg (P < .021, OR = 3.600, CI = 1.214–10.672) were possible risk factors for DGF. When only living-related recipients were considered, the systolic blood pressure level was significantly associated with DGF. We concluded that a pretransplantation systolic blood pressure level <120 mm Hg is a risk factor for DGF and that preoperative blood pressure control and intervention may help to decrease the risk of DGF.
