Acute haemorrhage from the upper portion of the gastrointestinal tract is a frequent complication which develops in ca 35-66 % of patients with cirrhosis of the liver and portal hypertension. It is assumed that one of the trigger mechanisms of varicose haemorrhage can be bacterial infection. However accurate data on the influence of infection on the development and course of haemorrhage are still lacking. The mortality of patients bleeding from oesophageal varices is very high (30 - 70 %). Usually the cause of death is not haemorrhagic shock but haemorrhage-induced changes which lead to hepatic failure. It is assumed that in this very process an important part is played by bacterial infection with subsequent release of endotoxins. Most recent metaanalyses indicate that bacterial infection is an independent prognostic factor as regards failure to arrest haemorrhage and influences in a significant way the mortality of these patients. Antibiotic treatment of patients with varicose haemorrhage increases the survival period of these patients. Therefore to cirrhotic patients with varicose haemorrhage antibiotics should be administered prophylactically, i.e. not only to patients with evidence of infection but also those without these symptoms. The authors consider as the optimal antibiotic treatment administration of quinolones orally or by the i.v. route, possibly cephalosporins which seem to be equally effective as quinolones.
