BACKGROUND In recent years, the confidential unit exclusion (CUE) option has been used to increase blood safety at blood transfusion centers in several countries. The epidemiologic characteristics of diseases and demographic characteristics of patients vary in different countries; therefore, we investigated whether the CUE option is useful in Iran. In this study, we determined the prevalences o...

BACKGROUND Hepatitis B virus, with 8 known distinct genotypes, is one of the most serious health problems which results to liver injuries. The surface gene of Hepatitis B virus completely overlaps with the polymerase gene. Mutations in the RT gene result in changes in the overlapping hepatitis B surface antigen. OBJECTIVES The present study aimed to evaluate the genotypes and prevalence of mu...

BACKGROUND The objective of this study is to estimate the average diagnosis and treatment costs of chronic hepatitis B and C, with respect to different therapeutic strategies in Iran. METHODS This is a descriptive, analytical, and cross-sectional study carried out on patients with hepatitis B and C, who were referred to the Liver Disease Research Center for Prevention and Treatment of Hepatit...

Background Hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are the main causes of severe liver failure worldwide. This study was conducted to evaluate the incidence rate and trend of these infections over six successive years from 2008 to 2013 in Ilam Province, western Iran. Methods We studied the registered data of HBV and HCV based on the National Notifiable Diseases Surveill...

I most Asian countries, with a general carrier rate of 5%–35%, hepatitis B virus (HBV) infection is hyperendemic (1). HBV is a member of Hepadnaviridae, a family of enveloped hepatotropic DNA viruses. It has a circular, partially doublestranded DNA of 3200 nt (2). This virus can cause severe liver disease with eventual progression to cirrhosis and primary hepatocellular carcinoma (HCC) (3). HBV...

OBJECTIVES HBV infection is a contagious disease that may transmit vertically from mothers to their neonates or horizontally by blood products and body secretions. Over 50% of Iranian carriers have contracted the infection perinatally, making this the most likely route of transmission of HBV in Iran. This study assesses the serologic markers of HBV in children born to HBsAg positive mothers who...

BACKGROUND Hepatitis B Virus (HBV) causes acute and chronic liver disease worldwide. HBV has eight genotypes (A to H) which is the reflection of its genome with their characteristic geographical distribution. Each genotype could have different pathogenic and therapeutic characteristics. There have been few records on HBV genotyping in general population from our region. This study aimed to dete...

Background and Aims: Hepatitis B virus (HBV) infects the liver and causes acute and chronic hepatitis, hepatocellular carcinoma and cirrhosis. HBV has been divided to eight genotypes (A–H) and subgenotypes of A, B, C and F. For the first time, we determined HBV genotypes in infected samples by INNO-LiPA method in Yazd, central province of Iran. Materials and Methods: This study was performed...

This study was conducted to find out the prevalence, viral load and co-infection of HBV and HCV infection among patients seeking to hospital care in Mashhad, Iran. A total of 402 samples (349 samples for HBV and 53 for HCV) were received and were screened for hepatitis B and C during 2004 to 2014. Viral loads of HBV DNA and HCV RNA were quantified by real-time PCR. Among 349 collected samples, ...

Mutations in the core promoter and precore regions of HBV cause down-regulation of HBeAg. These mutations are associated with chronic hepatitis, cirrhosis and Hepato Cellular Carcinoma (HCC). This study was carried out to sequence analysis of HBV core gene in HBsAg- positive blood donors in Iran. A total of 50 HBsAg- positive blood donor samples were examined in this study. Serological markers ...
