Abstract Background and Objectives Hepatitis B virus (HBV) infection remains a serious global health challenge. Hepatitis B infection is one of the major diseases transmitted by blood transfusion. Infection with the virus can cause extensive liver damage. So far, 10 genotypes have been identified for hepatitis B. The aim of this study was to do Hepatitis B virus genotyping in asymptomatic HBV...
conclusions in conclusion, the prevalence of hbv infection was low in the south of iran, but genotype d represented the major hbv genotype in this population. among the variables, age, duration of hd, history of blood transfusion, and using shared hd devices influenced the prevalence of hbv among hd patients. results both kinds of assay determined that nine (5.88%) patients were hbv positive (h...
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 (...
conclusions it appears that anti-hav antibody seroprevalence has declined among children below 15 years with and without chronic liver disease, and it is likely that more children would be susceptible to hav infection. therefore, it is important to employ preventative strategies against hav in chronic liver diseases. results seroprevalence of hav was 17.8% and 10% in the first and second study,...
Background & Aim: HBV is hepatotrophic virus that usually causes infection without any symptoms and it is a very important infective factor in patients with acute lymphoblastic leukemia because they need blood products during their treatment. Because of the importance of this subject the aim of this study was to use hepatitis B virus vaccination in patients who did not have immunity for thi...

background and aims: recently, a novel dna virus was isolated from the serum of a patient with post-transfusion non a-g hepatitis and named tt virus. the aim of this study was to determine the prevalence tt virus among cirrhotic patients due to hepatitis b & c in infection ahwaz. methods: the prevalence of ttv infection was studied in 41 patients with liver cirrhosis. ttv dna was detected by se...
Background: TT virus is a newly described DNA virus that was first detected in the blood of patients with elevated serum aminotransferases following transfusion who were tested negatively for all known hepatitis viruses. This study aimed to elucidate the significance of TTV infection in Iranian patients with autoimmune hepatitis. Materials and methods: Sera from 90 patients with autoimmune hep...
background: approximately 600,000 deaths occur every year as a result of the acute and chronic consequences of hepatitis b virus infection. ten different hepatitis b virus genotypes have been identified with distinct geographical distributions. different clinical outcomes, including the rate of mutations, development of hepatocellular carcinoma, chronicity, response to treatment, transplantatio...
Literature review shows that hepatitis C infection may increase the risk of non-hodgkin lymphoma. Reactivation of hepatitis B infection has been reported in patients with hairy cell leukemia after chemotherapy and/or splenectomy. We present hepatitis B surface (HBs) antigenemia and concurrent hepatitis C virus (HCV) seropositivity in a case of hairy cell leukemia. Key Words: Hairy cell leukemi...
