BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease and represents a wide spectrum ranging from mild steatosis over non-alcoholic steatohepatitis with and without fibrosis to overt cirrhosis. Patients with NAFLD have a high risk of developing cardiovascular disease and chronic kidney disease (CKD). So far, there is scarce evidence of the prevalence of NAFLD among patients with CKD. We investigated the prevalence of moderate-to-severe hepatic steatosis graded according to the definition of NAFLD in a cohort of patients with CKD.

METHODS: Hepatic liver fat content was evaluated by computed tomography (CT) scan in 291 patients from the Copenhagen Chronic Kidney Disease Cohort Study and in 866 age- and sex-matched individuals with normal kidney function from the Copenhagen General Population Study. Liver attenuation density <48 Hounsfield units was used as cut-off value for moderate-to-severe hepatic steatosis.

RESULTS: The prevalence of moderate-to-severe hepatic steatosis was 7.9% and 10.7% (P = 0.177) among patients with CKD and controls, respectively. No association between liver fat content and CKD stage was found. In the pooled data set from both cohorts, adjusted odds ratios for moderate-to-severe hepatic steatosis among persons with diabetes, overweight and obesity amounted to 3.1 (95% confidence interval (CI) 1.6-5.9), 14.8 (95% CI 4.6-47.9) and 42.0 (95% CI 12.9-136.6), respectively.

CONCLUSIONS: In a cohort of 291 patients with CKD, kidney function was not associated with the prevalence of moderate-to-severe hepatic steatosis as assessed by CT scan.
