Differences in medication adherence between preemptive and post-dialysis young kidney transplant recipients

Area of Science:

• Nephrology
• Transplantation immunology
• Clinical medicine

Background:

• Preemptive kidney transplantation is associated with superior graft survival compared to transplantation after dialysis.
• The underlying mechanisms for this improved survival are not fully understood.
• Medication adherence is critical for long-term transplant success.

Purpose of the Study:

• To compare medication adherence between young kidney transplant recipients who received a preemptive transplant versus those transplanted after a period of dialysis.
• To investigate if adherence differences contribute to the observed disparities in graft survival.

Main Methods:

• Secondary analysis of the Teen Adherence in Kidney transplant Effectiveness of Intervention Trial (TAKE-IT).
• Electronic monitoring assessed adherence over 15 months in 11-24-year-old recipients.
• Ordinal logistic regression with generalized estimating equations analyzed the association between preemptive transplantation and adherence, adjusting for multiple covariates.

Main Results:

• The study included 43 preemptive and 103 post-dialysis transplant recipients.
• Median adherence was higher in preemptive recipients (85.1%) compared to post-dialysis recipients (80.0%).
• Preemptively transplanted recipients had significantly higher odds of adherence (adjusted OR 1.76, p=0.003).

Conclusions:

• Preemptively transplanted patients demonstrate significantly better medication adherence than those who received dialysis prior to transplantation.
• This enhanced adherence in preemptive recipients may partially explain the superior graft survival outcomes.
• Findings suggest patient selection for preemptive transplantation may favor individuals with higher adherence potential.
