[Long-term pharmacological treatment of portal hypertension].
Portal hypertension is an unavoidable complication of liver cirrhosis, which usually limits the survival (bleeding from esophageal varices, ascites). Increase in portal pressure is not only due to mechanical obstruction of portal circulation, but there is also a dynamic component (endothelial dysfunction of hepatic microcirculation) and increased blood flow through the splanchnic circulation. For the long-term treatment of portal hypertension two groups of medicaments are available at present: non-selective betablockers (vasoconstriction in splanchnic bed) and nitrates (lowering of intrahepatic resistance). Long-term treatment is necessary in these situations: Primary prophylaxis of bleeding from esophageal varices (in patients, who never bled, but with "risk" varices)--non-selective betablockers; secondary prophylaxis (in patients after variceal bleeding)--non-selective betablockers (possibly with nitrates) or endoscopic treatment. It is clearly documented, that this treatment lowers the risk of the first or repeated bleeding from varices and hence lowers the mortality and morbidity due to this complication in patients with liver cirrhosis. Another serious complication of liver cirrhosis is the spontaneous bacterial peritonitis. All patients after that infection have to receive prophylactic treatment with antibiotics. This treatment should be long life, till the disappearance of ascites or till the liver transplantation.
