Non-Immunologic Causes of Late Death-Censored Kidney Graft Failure: A Personalized Approach

Area of Science:

• Nephrology
• Transplantation Immunology
• Clinical Medicine

Background:

• Long-term survival of kidney transplants remains suboptimal despite advancements.
• Antibody-mediated rejection and autoimmune diseases are common causes of late graft failure.
• Non-immunologic factors also critically impair transplanted kidney function.

Purpose of the Study:

• To review and discuss significant non-immune causes of late, death-censored kidney graft failure.
• To explore the etiopathogenesis and consequences of these risk factors on graft function.
• To highlight the potential for synergistic negative interactions between multiple risk factors.

Main Methods:

• Narrative review of existing literature.
• Identification and discussion of key non-immunologic risk factors.
• Analysis of the impact of these factors on kidney allograft outcomes.

Main Results:

• Key non-immune factors include donated kidney quality, medication adherence, drug toxicities, hypertension, dyslipidemia, new-onset diabetes mellitus, hyperuricemia, and recipient lifestyle.
• These factors contribute to graft dysfunction and failure through various mechanisms.
• Multiple risk factors often interact, exacerbating negative consequences.

Conclusions:

• Non-immunologic factors represent critical targets for improving long-term kidney transplant outcomes.
• Comprehensive management strategies should address donated kidney quality, patient adherence, and modifiable lifestyle/metabolic factors.
• Understanding and mitigating these risks are essential for reducing late kidney graft failure.
