“Hepatitis B virus (HBV) is a global health problem and major cause of cirrhosis, fulminant hepatitis and hepatocellular carcinoma. Hepatitis D is dependent on HBV for its reproduction. Approximately 5% of the global population is infected with HBV. This translates to over 400 million HBV carriers worldwide. It is estimated that 1.4 million people

in the USA have chronic hepatitis B with 46 000 documented new HBV infections in 2006. HBV is transmitted by vertical transmission (perinatal) or horizontal transmission. The key to prevention is elimination of further spread of infection. Persons with chronic HBV infection can be asymptomatic and have no evidence of liver disease, or they can have a spectrum of disease, ranging from chronic hepatitis to cirrhosis or liver cancer. US mortality data for 2000–2003 indicated that HBV infection was the underlying cause of an estimated 2000–4000 deaths annually. The majority PI3K inhibitor of these deaths resulted from cirrhosis and liver cancer. Treatment of chronic hepatitis B is aimed at viral suppression to reduce damage to the liver and its consequences, cirrhosis and HCC, and improve overall survival rate. There are seven drugs

currently approved by the Food and Drug Administration (FDA) for treatment of hepatitis B. The general treatment guidelines BAY 73-4506 (EASL and AASLD HBV Guideline recommendations) are reviewed and will provide further information in difficult to treat populations such as compensated/decompensated cirrhotics and treatment during pregnancy. selleck kinase inhibitor “
“Malignancies of the gallbladder and bile ducts are uncommon tumors of the gastrointestinal tract. Presentation of gallbladder

cancer can vary from an incidental pathologic finding after cholecystectomy to invasion of the liver, bile ducts and other perihepatic structures. Surgical resection is the mainstay of therapy; the extent of resection depends on the depth of tumor invasion into the gallbladder wall, liver, and invasion of local structures. Hilar cholangiocarcinoma (e.g. Klatskin’s tumor) often presents with painless jaundice. Hepatic resection is usually required to achieve a potentially curative resection. Unfortunately, many tumors are unresectable at the time of presentation. Liver transplantation following neoadjuvant therapy has emerged as an effective treatment for selected patients with early stage hilar cholangiocarcinoma that is either unresectable or arising in the setting of primary sclerosing cholangitis. “
“Serum des-γ-carboxy prothrombin (DCP) levels using a newly developed electrochemiluminescence immunoassay (ECLIA, novel DCP [NX-DCP]) were measured, and the utility of NX-DCP and DCP/NX-DCP ratio for the diagnosis of hepatocellular carcinoma (HCC) was investigated. Antigenic differences in DCP between HCC and non-HCC patients were elucidated. The subjects included 170 patients with HCC, 61 with benign liver disease, 12 with obstructive jaundice, and 10 warfarin users.
