[Patients with chronic liver disease, mostly the elderly, due to their impaired immune response, frequently suffer from infections worsening the clinical course. This is sometimes overlooked in the everyday praxis. In patients with alcoholic liver disease both hepatitis A virus (HAV) and acute hepatitis B virus (HBV) infections can lead to fulminant hepatic failure, therefore their immunization with HAV and HBV vaccines is highly recommended, similarly, vaccination against flu and pneumococcus also may be indicated for alcoholics. In chronic viral hepatitis, alcohol abuse can result in rapid progression to cirrhosis and reduces the efficacy of antiviral treatment. Patients with chronic hepatitis C should also be vaccinated against superinfections by HAV and HCV. Co-infections by hepatotropic viruses and human immundeficiency virus (HIV) are frequent due to the shared routes of transmission. In HIVpositive patients the efficacy of the vaccination against HAV and HBV depends on the CD4 cell count, which also determined the timing of anti- HBV or anti-HCV treatment. Concerning the bacterial infections, spontaneous bacterial peritonitis (SBP) is the most severe complication of cirrhosis. The prevention of SBP is orally administered, moderately absorbed quinolon (norfloxacin) as long-term selective intestinal decontamination against Gram-negative pathogens. Alcoholic patients are also susceptible for tuberculosis. Bacterial infections play a role even in portal hypertension and variceal rupture, furthermore, both gastrointestinal haemorrhage and invasive endoscopic procedures increase the risk of infection, therefore in such situations a short-term (5- 8 day) antibiotic profilaxis is necessary with norfloxacin or ciprofloxacin. Taking into consideration these points of view, it may be of privotal significance for the management of patients with liver disease.]

[SELECTIVE α1-ADRENORECEPTOR ANTAGONISTS IN CARDIOVASCULAR MEDICINE]

RÓNASZÉKI Aladár

[A hypertonia korszerű kezelésében a szelektív α1-adrenoreceptor-antagonisták ma is jelentős szerepet játszanak. A hatékony vérnyomáscsökkentés mellett számos előnyös, járulékos hatásuk révén sok társbetegséget (diabetes mellitus, atherogen dyslipidaemia, obliteratív érbetegség, prostatahypertrophia, erectilis diszfunkció) is kedvezően befolyásolnak. A hypertoniához társuló szívelégtelenségben, illetve annak elkerülése érdekében monoterápiában nem alkalmazhatók. Az α1-adrenoreceptor-antagonisták kombinációja diuretikummal mindig javasolt.]

[MANAGEMENT OF LIFE-THREATENING ENDOSCOPIC THERAPY-RESISTENT OESOPHAGUS VARICEAL BLEEDING]

ERŐSS Bálint Mihály, SZÉKELY György, SIKET Ferenc, LÁZÁR István

[INTRODUCTION - Liver cirrhosis has two serious consequences: hepatic failure and portal hypertension. Portal hypertension has two important clinical appearances: variceal bleeding and therapy resistant ascites. Variceal bleeding can be recurrent and resistant to endoscopic treatment. These complications can be prevented by implantation of Transjugular Intrahepatic Portosystemic Shunt (TIPS). CLINICAL CASE - A 59 year old male with cirrhosis due to hepatitis C, was hospitalized in our department in April 2004 with variceal bleeding. We tried to control the bleeding twice by band ligation, once by sclerotherapy and with the use of Sengstaken-Blakemore tube, but bleeding continued for three weeks despite the endoscopic treatment. The patient needed intensive care therapy and was treated with more than forty units of packed red cells and plasma. At that point we decided to implant a TIPS, which was carried out succesfully. After TIPS implantation no rebleeding occured and the shunt had good patency. Moderate hepatic encephalopathy was observed, which is a well known phenomenon, but it could be treated with pharmacologic therapy. CONCLUSIONS - In case of portal hypertension TIPS implantation can prevent from variceal rebleedings and may caus significant improvement in the quality of life.]

[Drug treatment possibilities in chronic liver diseases]

HAGYMÁSI Krisztina, LENGYEL Gabriella, FEHÉR János

[Alcoholic and drug induced liver diseases, nonalcoholic steatohepatitis, hepatitis C and B chronic hepatitis, autoimmune diseases (primary biliary cirrhosis, primary sclerosing cholangitis, autoimmune hepatitis) and metabolic disorders (hemochromatosis, Wilson's disease) are the main chronic liver diseases. Authors summarize, based on the latest literature data, the medications of chronic liver diseases, emphasizing the treatment of the everyday practice. Natural and synthetic antioxidants are approved for the treatment of chronic alcoholic liver diseases besides abstinence, with diet of adequate quality and quantity. Nucleoside analogues (lamivudin) are recommended for the first-line therapy of the treatment of chronic hepatitis B. Interferon is presently considered the optimal treatment for only certain patients. Interferon and ribavirin combined therapy is well-established in the treatment of chronic hepatitis C. Ursodeoxycholic acid is the beneficial treatment option for primary biliary cirrhosis and primary sclerosing cholangitis. Prednisolon and azathioprine constitute the basic therapy of autoimmune hepatitis. Presumably, in the future, new strategies based on immunosuppressive combinations will play a crucial role. The chelating deferoxamine has less important part in the treatment of hemochromatosis. D-penicillamine still plays principle role in the medication of Wilson's disease.]

[SERUM ALANIN AMINOTRANSFERASE VALUES AND CHRONIC HEPATITIS C - HOW MUCH IS “NORMAL”, AND WHO SHOULD BE TREATED?]

HUNYADY Béla

[Serum aminotransferases (= transaminases), especially alanin aminotransferase have been used in the diagnosis of liver diseases, including viral hepatitis, for decades. However, reliability of these biochemical markers was challenged in various respects by recent clinical studies. First, it has been shown not to be sensitive enough in screening for viral hepatitis in high risk populations (viral hepatitis may be present with normal values). Second, normal range is exceeded in a large number of subjects without genuine liver disease due to the increased proportion of people with metabolic disease (diabetes, dyslipidaemia) or high body weight, i.e., the upper limit of normal is too strict. Moreover, decision on treatment of patients with viral hepatitis infection and persistently normal aminotransferases poses a challenge for the clinician. Based on the current literature, this review attempts to provide guidelines for the everyday clinical practice.]
