Predicting long-term kidney graft failure using novel multi-omic blood-based biomarkers and artificial intelligence...

Area of Science:

• Nephrology and immunology
• Transplantation science

Background:

• Kidney transplantation (KT) is the optimal treatment for end-stage renal disease, with improving short-term graft survival.
• Aging populations and expanded donor criteria present new challenges in KT management.
• Existing prediction tools for KT outcomes are limited by variable definitions, small sample sizes, and lack of external validation.

Purpose of the Study:

• To highlight the need for advanced prediction tools for long-term kidney transplant outcomes.
• To discuss the complex molecular mechanisms of chronic allograft rejection.
• To explore the potential of artificial intelligence and machine learning in understanding these mechanisms.

Main Methods:

• Review of current literature on kidney transplantation, immunosuppression, and graft failure.
• Analysis of molecular mechanisms involved in chronic allograft rejection, including immune cell interactions and fibrotic processes.
• Discussion of the application and limitations of omics profiling and AI/ML in predicting KT outcomes.

Main Results:

• Graft survival improvements are primarily short-term, necessitating better long-term prediction.
• Chronic allograft rejection involves complex immune responses and fibrotic pathways.
• Current omics-based prediction tools and AI/ML applications require further validation and data quality improvements.

Conclusions:

• There is a critical need for robust, validated prediction tools to guide KT management and improve long-term graft survival.
• Understanding the intricate molecular mechanisms of chronic rejection is essential for biomarker discovery.
• Advanced computational approaches like AI/ML hold promise but require high-quality, representative data for clinical utility in kidney transplantation.
