Hepatitis delta virus (HDV) is a defective virus that requires the supply of hepatitis B virus surface antigen (HBsAg) for replication and transmission. We have previously demonstrated that co-transduction of BHK cells with BacGD, a recombinant baculovirus expressing large hepatitis delta antigen (L-HDAg), and Bac-GS2, another recombinant baculovirus expressing HBsAg, gives rise to the assembly...
IgM antibody against hepatitis B core antigen (IgM anti-HBc), a marker of recent hepatitis B virus infection, was sought by radioimmunoassay in sera diluted 1/4000 from 376 patients presenting to four centres in Italy with acute, apparently type B hepatitis (hepatitis B surface antigen (HBsAg) positive). In 320 patients (85%) a positive IgM anti-HBc test result confirmed that hepatitis was due ...
Viral hepatitis is one of five infectional factors cause early death in all over the world. Every day at least one million people die because of viral hepatitis. Six hepatitis viruses have been known until now. They are A, B, C, D, E, G, and it is probable that at least two other kinds i.e. F, and H, will be known soon. Only hepatitis B is a DNA virus, and the others are RNA viruses. All viruse...
Hepatitis viruses (HAV, HBV, HCV, HDV and HEV) are attributed to a wide spectrum of acute and chronic liver diseases, including carcinomas. Worldwide, >250 million become chronically infected by HBV and ~150 million by HCV every year. Though, new hepatotropic viruses, such as HGV, GBV, TTV and SENV are identified in chronic liver diseases, thousands still suffer of unknown etiology. Despite a p...
BACKGROUND The only established therapy for chronic viral delta hepatitis, the most severe form of viral hepatitis is treatment with pegylated-interferon α (Peg IFN α). OBJECTIVES In this study, we aimed to determine the efficacy of pegylated-interferon α 2a (Peg-IFN α 2a) and 2b (Peg IFN α 2b) in the treatment of patients infected with chronic delta hepatitis virus. PATIENTS AND METHODS Th...
Background: Superinfection of hepatitis A in chronic hepatitis B and C may worsen the course of disease. This study attempted to study frequency of hepatitis A virus antibodies in patients with hepatitis B and hepatitis C. Materials and methods: 115 hepatitis C and 56 hepatitis B patients who visited the Hepatitis Association of Hamedan province during 2004-2005 were enrolled. Hepatitis A viru...
Background and Aim: Cytokines are believed to play an important role in the regulation of cellular immune response in hepatitis B virus infection. Interleukin 10 is a member of cytokine family. The overall expression of these molecules is mainly controlled by single nucleotide polymorphisms at specific sites on the promoter region of the Interleukin 10 gene. The aim of this study was to a...
UNLABELLED There is controversial data in the literature about the characteristics or features of dual hepatitis B and C infection. Several studies have reported that the dual infection has a more severe histological picture; faster progression leading to cirrhosis and a higher risk for hepatocellular carcinoma compared with the single infections. These findings have not yet been supported. We ...

OBJECTIVE Although the clinical and histopathological findings of hepatocellular carcinoma are well described, there are few national studies. In this study, we aimed to investigate the relationship between these findings in total or partial hepatectomy specimens in our series. MATERIAL AND METHOD We first collected 190 cases of total or partial hepatectomies performed because of hepatocellul...
