background: hepatitis e virus is an enterically transmitted virus that is endemic in south asia and this virus is one of the most important cause of acute hepatitis in this region. although hepatitis e virus (hev) is not a leading cause for chronic hepatitis, the role of hev in exacerbation of chronic liver disease is certain. materials and methods: 100 cirrhotic cases (50 hepatitis b and 50 he...

800x600 hepatitis b virus (hbv) infection is the main cause of chronic hepatitis, cirrhosis and hepatocellular carcinoma (hcc). several factors such as serum hbv dna level, genotype and specific viral mutations have been clarified to determine disease progression of chronic hepatitis b. among these, mutations can also occur in chronic hbv patients with antiviral treatment such as lamivudine the...

Background Infants of diabetic mothers (IDMs) have significantly greater risk for spontaneous abortion, stillbirth, congenital malformations and perinatal mortality and morbidity but whether maternal DM affects the neonatal innate immune system is unknown. We aimed to assess the immune response of infants of diabetic mothers (IDMs) with non-gestational DM for Hepatitis B vaccine and to compare ...

background and aims: many studies have provided evidence for the role of hepatitis b and c viruses in the development of liver cancer. although the routine treatment is available for both conditions, no definite guideline is available to treat patients dually infected with hbv and hcv. this study was performed to determine the frequency of hbv/hcv-coinfection in mashhad, north-east of iran. mat...

Background: Although regular frequent blood transfusion improves overall survival of multi-transfused patients like β-thalassemic ones, it carries a definite risk of infection with blood-borne viruses such as viral hepatitis. This study was done to determine seropositivity of hepatitis B virus (HBV), hepatitis C virus (HCV), and Human Immunedeficiency Virus (HIV) infections among β-th...

 ABSTRACT Background: Hepatitis B virus (HBV) infection in patients who lack detectable hepatitis B surface antigen (HBsAg) is called occult hepatitis B infection. Such infections have been frequently identified in patients with chronic hepatitis Cliver disease, but their prevalence is not known. Methods: 207 patients with chronic hepatitis C who were HCV -RNA and antiHCV positive were stu...

background: hepatitis a virus (hav) is highly contagious in individuals living in crowded conditions such as military centers. objectives : this study try to investigate the seroprevalence of hav immunity among iranian soldiers and determine whether vaccination should be used for military draftees. patients and methods: in this cross-sectional study, a total of 1554 soldiers were recruited thro...

BACKGROUND Hepatitis A virus (HAV) has a worldwide distribution, although this distribution tends to be uneven among geographical regions and population groups. The prevalence of anti-HAV antibodies in the general population varies widely among countries. In Europe, the seroprevalence of HAV is reported to range from 32% to 88%. OBJECTIVES The aim of this study was to determine the seropreval...

AIMS Estimating the force of hepatitis A virus (HAV) infection concerning a 1- to 15-year-old child population being attended at six healthcare centres in Colombia by applying catalytic models. METHODS Anti-HAV seroprevalence was estimated in 2,152 patients attending six health centres in 5 Colombian cities; based on such estimation, the force of infection and average age of infection were ob...
