title: [Clinical features and predictive factors of acute hepatitis A complicated with acute kidney injury].
abstract: OBJECTIVE
  we assessed the clinical features and prognosis of acute viral hepatitis A (AHA) complicated with acute kidney injury (AKI) and elucidated predictive factors for AKI in patients with AHA.
  
  
  METHODS
  we reviewed medical record of 391 patients with AHA admitted at our institution since 2000.
  
  
  RESULTS
  AKI was present in 45 patients (11.5%). The proportion of the AKI group increased since 2008 (5.4% before 2008 vs. 15.9% since 2008, p=0.001). The AKI group was older than the non-AKI group (35.7+/-8.7 years vs. 31.3+/-7.8 years, p=0.002). Other baseline clinical characteristics were similar between two groups. Initial hemoglobin, platelet, and serum albumin were significantly low and prothrombin time, serum bilirubin, creatinine, AST, and ALT were significantly high in the AKI group. Hepatic encephalopathy, ascites, gastrointestinal bleeding, and sepsis were more frequently observed in the AKI group. While six patients (13%) in the AKI group received liver transplantation (LT) but three patients died within one month, one patient in the non-AKI group receiving LT is alive. Multivariate analysis showed that older age (OR 1.07, 95% CI 1.02-1.12), initial thrombocytopenia <150,000/mm2 (OR 2.85, 95% CI 1.24-6.57), prothrombin time (PT) prolongation (OR 5.34, 95% CI 2.55-11.19), and hypoalbuminemia (OR 8.24, 95% CI 2.53-26.86) were independently associated with the occurrence of AKI.
  
  
  CONCLUSIONS
  AHA with AKI is an increasing problem showing significant morbidity and mortality in Korea. AKI is highly associated with older age, initial thrombocytopenia, PT prolongation, or low serum albumin, and has bad prognostic effect.
