Abstract Background Although acute hepatitis A is usually self-limited, the clinical manifestations can vary from mild to severe liver dysfunction. However, little is known about risk factors for and outcomes of acute kidney injury (AKI) in acute hepatitis A. Objectives To identify the risk factors for and outcomes of AKI in acute hepatitis A. Study design We identified 396 patients with acute hepatitis A, which registered between January 2006 and June 2009 at a tertiary care university hospital. Retrospective case-control studies were conducted in order to identify risk factors for AKI. Results Thirty patients (7.6%) developed AKI. On multivariate analysis, fulminant hepatitis, leukocytosis, and elevated CRP were independent risk factors for AKI associated with hepatitis A, and higher total bilirubin, leukocytosis, and elevated CRP were independent risk factor for AKI within nonfulminant hepatitis A. Of the 30 patients with AKI, 23 (76.7%) patients fully recovered, 2 patients maintained hemodialysis after hospital discharge and 5 patients died due to hepatic failure without recovery from AKI. Among 20 patients with AKI in nonfulminant subgroup, 19 patients (95%) recovered without hemodialysis. Conclusions AKI is not a rare complication of acute hepatitis A and severity of hepatitis and hepatic injury influence the development of AKI in acute hepatitis A.
