title: Serious hepatitis A: an analysis of patients hospitalized during an urban epidemic in the United States.
abstract: BACKGROUND
  Memphis and Shelby County, Tennessee, experienced an epidemic of hepatitis A in 1994 and 1995. More than 1700 cases were reported.
  
  
  OBJECTIVE
  To characterize the clinical features of patients hospitalized during a large urban epidemic of hepatitis A.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  15 acute care hospitals in Shelby County, Tennessee.
  
  
  METHODS
  256 patients hospitalized with acute hepatitis A.
  
  
  METHODS
  Laboratory findings (such as prothrombin time and bilirubin level), complications, and mortality.
  
  
  RESULTS
  The median patient age was 26 years. Thirty-nine complications occurred in 35 patients. Twenty patients (8%) had extrahepatic complications, and 5 (2%) died. Patients 40 years of age and older were more likely to have serious complications, including death (P = 0.014). Sixty-seven patients (26%) presented with coagulopathy (prothrombin time > or = 3 seconds prolonged). Fifty-four patients (21%) had a bilirubin level greater than 170 micromol/L (10 mg/dL).
  
  
  CONCLUSIONS
  During this epidemic, hepatitis A caused serious illness and death. Complications were more frequent in patients 40 years of age and older, but young, healthy persons were also at risk for severe complications.
