Asymptomatic hepatitis B infection is characterized as a type of hepatitis in which hepatitis B surface antigen is present in the patient's peripheral blood despite the absence of clinical symptoms. Previous studies have shown that a particular genotype may effect clinical manifestations of hepatitis B infection; hence, the aim of the current study was to determine the frequency of hepatitis B ...

abstract   background: hepatitis b virus infection is an important cause of liver morbidity and mortality worldwide. hdv changes the natural course of hbv. the prevalence of hdv infection wasn’t determined in the various groups of hbv infection (carriers, acute hepatitis, chronic hepatitis, cirrhosis and hcc) in iran. we aimed to research the prevalence of hepatitis d virus infection in various...

In 1967, it was reported that experimental inoculation of serum from a surgeon (G.B.) with acute hepatitis into tamarins resulted in hepatitis. In 1995, two new members of the family Flaviviridae, named GBV-A and GBV-B, were identified in tamarins that developed hepatitis following inoculation with the 11th GB passage. Neither virus infects humans, and a number of GBV-A variants were identified...

The prevalence of viral hepatitis is high and remains a serious public health challenge throughout the world. New molecular biology techniques provided a better understanding of the viruses over the last decades. Novel therapeutic options seem to be promising but preventing measures including donor screening, immunization against hepatitis A virus (HAV) and hepatitis B virus (HBV), universal us...

BACKGROUND Viral hepatitis with various forms of acute and chronic liver disease as potential and ultimately fatal sequelae presents a public health problem worldwide. METHODS Recent published reports on the global epidemiology and prophylaxis of viral hepatitis were reviewed. RESULTS With the advances in novel technologies, eight distinct types of hepatitis virus have been described: Hepat...

Background and Aims: Iron oxide nanoparticles are among the most effective tools which can replace current medical techniques for diagnosis and treatment of various diseases. Hepatitis C infection is one of the main health problems in the world, affecting around 3% of the world's population. This infection can develop into liver cirrhosis and liver cancer over the time in 80% of patients. In t...

Antiviral drugs have an established role in the management of selected patients with chronic viral hepatitis. Of the hepatitis viruses (A to E), hepatitis B virus (HBV), hepatitis C virus (HCV) and hepatitis D virus (HDV) (also called delta virus) cause chronic hepatitis with the potential for development of cirrhosis and its complications, including primary hepatocellular carcinoma (HCC). HDV ...

Background and Aims: Viral hepatitis is a global health problem with a high mortality rate. Recently, a new Flavi-like virus, provisionally named hepatitis G virus (HGV), has been described. HGV does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (...
