Fulminant hepatitis is rare (1% of cases) but very serious. His mortality is 50 to 80%.

The symptoms are impressive:

  • Hepatic encephalopathy;
  • Haemorrhages (purpura, hematemesis);
  • Metabolic disorders: a collapse of coagulation factors, hypoglycemia, hyperammonemia, acid-base disorders, etc .;
  • Acute hepatitis A: jaundice lasts longer than usual, but never becomes chronic;
  • Acute hepatitis B: the transition to chronic disease is possible.


  • Subacute hepatitis, the symptoms are marked, neurological signs can be seen, a progression towards chronicity or even fatal is possible;
  •  Cholestatic hepatitis: Hepatitis is complicated by cholestasis, the evolution is long but usually favorable.


  • Asymptomatic carriers: these patients carry the hepatitis B virus, but no symptoms, their blood is contagious;
  • Persistent chronic hepatitis usually occurs after acute hepatitis A or B. Healing is the rule;
  • Chronic active hepatitis  (B or C) is a serious disease that can progress to cirrhosis or liver cancer;
  • Liver cancer occurs after 10 to 30 years of chronic hepatitis.

Other complications are immunological: joint or muscle pain, anemia, kidney damage, etc.
