Preemptive Living Donor Kidney Transplantation and Kidney Function at the Initial Hospital Visit: A Single-Center...

Area of Science:

• Nephrology
• Transplantation Immunology
• Clinical Medicine

Background:

• Preemptive kidney transplantation (PKT) is associated with better patient prognoses than transplantation after dialysis initiation.
• The global incidence of PKT is rising, necessitating identification of suitable candidates.
• Understanding clinical factors for successful PKT is crucial for improving patient outcomes.

Purpose of the Study:

• To identify clinical characteristics predictive of successful preemptive kidney transplantation (PKT).
• To compare baseline characteristics of patients undergoing successful versus failed PKT.
• To establish criteria for timely referral and execution of PKT.

Main Methods:

• A single-center, case-control study design.
• Comparison of baseline clinical data between patients who received PKT before dialysis (successful) and those who received it after dialysis initiation (failed).
• Statistical analysis to determine significant predictors of PKT success.

Main Results:

• Serum creatinine levels at the initial visit were significantly lower in the successful PKT group (6.0 ± 0.3 mg/dL) compared to the failed PKT group (7.5 ± 0.5 mg/dL).
• A serum creatinine level >5.7 mg/dL at the initial visit was identified as a cutoff point for predicting successful PKT, with an area under the curve of 0.721.
• The median time from initial visit to PKT was approximately 5.6 months.

Conclusions:

• Preemptive kidney transplantation (PKT) should ideally be performed within approximately six months of the initial transplant center visit.
• Pre-transplant serum creatinine levels below 5.7 mg/dL are indicative of successful PKT.
• Early identification and referral of suitable candidates are key to maximizing the benefits of PKT.
