Chronic kidney disease post-liver transplantation

Area of Science:

• Nephrology
• Transplantation Medicine
• Clinical Outcomes

Background:

• Renal disease is a known complication following orthotopic liver transplantation (OLT).
• Understanding the incidence and risk factors for chronic kidney disease (CKD) is crucial for post-transplant care.

Purpose of the Study:

• To determine the incidence of all stages of CKD post-OLT.
• To identify risk factors associated with CKD development and progression.
• To evaluate the impact of CKD on patient survival after OLT.

Main Methods:

• Analysis of 230 patients undergoing cadaveric OLT between 1993 and 2004.
• Glomerular filtration rate (GFR) calculated using the Modification of Diet in Renal Disease Study equation.
• Univariate and multivariate logistic regression for risk factors; Kaplan-Meier and Cox regression for survival analysis.

Main Results:

• 10-year cumulative incidence for CKD stages: 0/1 (9.61%), 2 (53.71%), 3 (56.77%), 4 (6.11%), 5 (2.62%).
• Risk factors for CKD progression include female gender, age, pre-OLT proteinuria, lower GFR, and higher creatinine; tacrolimus use was protective.
• Reduced survival associated with GFR <30 ml/min, re-transplantation, and fulminant hepatic failure.

Conclusions:

• Moderate CKD is highly prevalent after OLT.
• Key risk factors for CKD progression and reduced patient survival have been identified.
• Tacrolimus demonstrates a beneficial effect on CKD progression in OLT recipients.
