BACKGROUND Blood transfusion is considered a potential risk factor for transmission of life-threatening viral infections, including HIV, HCV and HBV infections. This study was performed to find out the prevalence and trends of these infections among blood donors in Southern Iran. METHODS The blood donor data recorded in twelve regional blood transfusion centers from 2004 to 2014 were analyzed...
INTRODUCTION Highly active antiretroviral therapy (HAART) has improved survival of human immunodeficiency virus (HIV) patients. Concurrent morbidities from liver diseases among these patients have also been observed due to co-infection with hepatitis B and C viruses (HBV and HCV). HAART reduces liver-associated morbidities and mortalities in such patients. Unfortunately free testing of HBV and ...
BACKGROUND/AIMS Few studies have investigated hepatitis A virus (HAV) seroepidemiology in Koreans with chronic liver disease (CLD). This study compared the prevalence of IgG anti-HAV between the general healthy population and patients with hepatitis B virus-related CLD (HBV-CLD), with the aim of identifying predictors of HAV prior exposure. METHODS In total, 1,319 patients were recruited betw...
BACKGROUND Characteristics of hepatitis B (HBV) and delta (HDV) coinfection in various geographical regions, including Israel, remain unclear. Here we studied HDV seroprevalence in Israel, assessed HDV/HBV viral loads, circulating genotypes and hepatitis delta antigen (HDAg) conservation. METHODS Serological anti HDV IgG results from 8969 HBsAg positive individuals tested in 2010-2015 were re...
Background. Transfusion-transmissible infectious agents such as human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV) and syphilis are among the greatest threats to blood safety for the recipient and pose a serious public health problem. The aim of this study was to determine the seroprevalence and risk factors for HIV, HBV, HCV and syphilis infections among blood...
Hepatitis B virus (HBV) infection is a serious public health problem in sub-Saharan Africa. The risk of vertical transmission increases if the mother is hepatitis B surface antigen (HBsAg) positive and more so when she is also hepatitis B envelope antigen (HBeAg) positive. Since 2000, the World Health Organization recommends screening of pregnant women for HBV infection. However, this is not cu...
Blood transfusion is an important mode of transmission of infections to recipients. The aim of the study was to assess the prevalence of transfusion-transmissible infections among blood donors. For this, a 3.5-year retrospective study, from October 2002 to April 2006 was conducted at the blood transfusion centre of Maharaja Agrasen Medical College, Agroha (Hisar) Haryana. Donors were screened f...
Background In this study, the long-term efficacy of hepatitis B virus (HBV) vaccination was assessed using seroprevalence and an age-period-cohort (APC) model of HBV seromarkers among university entrants 30 years after the introduction of the national neonatal HBV vaccination program in Taiwan. Methods In total, data of 17,611 university entrants who underwent university entrance health exami...
OBJECTIVES Hepatitis B virus (HBV) infection is a global health burden. In this regard, Egypt has an intermediate HBV seroprevalence. HBV is classified into ten different genotypes (A-J) with different geographic distributions. Genotype D is the most prevalent in the Middle East. Limited data are available about HBV genotyping among Egyptian blood donors, particularly in Upper Egypt. We examine...
The aim of the present cross sectional seroprevalence study was to determine the frequency of HBV carriers in pregnant women registered at the Gaziantep Maternity Hospital, Turkey. The records of a total of 11,840 pregnant women were examined retrospectively. HBsAg was detected in 252 (2.1%) of 11,840 women. The prevalence of HBV infection in pregnant women in the southern region of Turkey is a...
