Introduction

  • Viral hepatitis may be caused by a broad range of pathogens (Table 1)
  • Hepatic injury may be mild, with only transient elevation in aminotransferases, or may lead to acute hepatitis or fulminant hepatic failure
  • The effects of these viral infections on immunocompromised hosts, including recipients of solid organ transplantations, deserve special attention

Human viral hepatitis results from a wide range of pathogens beyond the classic hepatotropic viruses, hepatitis A through E (Table 1). Secondary and exotic hepatotropic viruses may cause hepatic injury ranging from mild and transient elevation of aminotransferases to acute hepatitis and, occasionally, to fulminant hepatitis.
