Abstract: Assessment of renal function in patients with end-stage liver disease (ESLD) awaiting liver transplantation (OLT) is critical. Various conditions may cause renal damage in ESLD. Renal and liver functions are intertwined due to splanchnic hemodynamic relationships; renal failure rarely occurs in patients without advanced decompensated cirrhosis. The recent literature suggests that evaluation of renal function should include an assessment of liver function. The aim of this study was to evaluate different methods to estimate glomerular filtration rate (GFR) in patient among ESLD candidates for OLT over 1 year. We also correlated renal and hepatic functions. Fifty-two cirrhotic patients Model for End-Stage Liver Disease [MELD] > 10) were enrolled in the study. All patients were evaluated at baseline and every 4 months (T1-T4) thereafter for 1 year. The GFR was calculated by creatinine clearance, and estimated by Cockroft and Gault, Modified Diet Renal Disease (MDRD) 4 and 6 variable and Chronic Kidney Disease-Epidemiology (CKD-EPI) formulae. Hepatic functions were evaluated by MELD score, albumin, bilirubin, and International Normalized Ratio (INR). We observed not statistically significant increase mean value of MELD score, bilirubin, serum creatinine, and blood urea nitrogen and a reduced serum sodium. There were no significant differences among various methods to evaluate CFR at each time over 1 year. We did not observe any association between renal and hepatic function, except at T4 for MELD and GFR estimated with MDRD 4 (P = .009) and 6 (P = .008) parameters or CICD-EPI (P = .036), and MELD and sodium (P = .001). Our results showed that evaluation of renal function in cirrhosis should include an evaluation of hepatic function. In our case, MDRD and CKD-EPI seemed to be the more accurate formulae to evaluate renal function in relation to hepatic function.
