    Abstract:
    BACKGROUND: Chronic kidney disease (CKD) is one of the major complications after liver transplantation (LT), with a significant impact on patient outcomes. This study aims to investigate the incidence and risk factors of CKD in LT recipients at Siriraj Hospital over the past 20 years. METHODS: There were 366 adult patients undergoing LT at Siriraj Hospital between January 2002 and December 2021. After excluding patients with pretransplant CKD stages 4 to 5, simultaneous liver-kidney transplantation, and patients who died after LT within 90 days, we retrospectively reviewed a total of 288 patients. Univariable and multivariable binary logistic regression analyses were used to identify the risk factors of post-transplant CKD. RESULTS: Of the 288 patients, 171 (59.4%) developed CKD after LT. The median time to develop CKD was 5.8 months (IQR, 3.8-15.3). Univariable and multivariable analyses revealed that age ≥55 years (odds ratio [OR] = 2.44; 95% CI, 1.34-4.42; P = .003), pretransplant kidney dysfunction defined as estimated glomerular filtration rate <60 mL/min/1.73 m2 (OR = 2.23; 95% CI, 1.16-4.27; P = .016), and postoperative acute kidney injury (OR = 3.06; 95% CI, 1.73-5.42; P < .001) were significantly associated with post-transplant CKD. Patients with preexisting kidney dysfunction who received delayed calcineurin inhibitor introduction without antibody induction protocol had a significantly lower incidence of post-transplant CKD (OR = 0.28; 95% CI, 0.11-0.70; P = .007). CONCLUSIONS: Advanced age, pre-transplant kidney dysfunction, and postoperative acute kidney injury are risk factors for CKD after LT. Importantly, delayed calcineurin inhibitor introduction can protect patients with pretransplant kidney dysfunction from developing post-transplant CKD. These results may have important clinical implications in reducing the incidence of CKD after LT.
