BACKGROUND AND AIM: Hepatitis B Virus (HBV), a DNA virus with a human-only reservoir, is a worldwide public health problem. Approximately 45.0% of the world’s population is considered to live in areas of high endemicity with a lifetime risk of infection of more than 60.0%. The present study aimed to assess the level of understanding and awareness about Hepatitis B immunization among the first a...
BACKGROUND Occult hepatitis B infection (OBI) is characterized by negative hepatitis B surface antigen (HBsAg) and detectable hepatitis B virus (HBV)-DNA in the liver and/or serum, with or without hepatitis B core antibody (anti-HBc). Anti-HBc is the most sensitive marker of previous HBV. HBV reactivation in patients under immunosuppressive treatment is life-threatening, occurring in both overt...
Background: Occupational risk of blood-borne infections is investigated mostly among nurses and doctors, studies concerning non-clinical health personnel (nCHP) being rare. The analysis of the occupational exposure to the hepatitis B virus (HBV) infection and the history of vaccination against the HBV in the nCHP group has been the aim of the study. Material and Methods: A retrospective anal...
هپاتیت b یکی از شایع ترین بیماریهای کبد در جهان میباشد، که عامل ایجاد کننده آن عفونت با ویروس هپاتیت b (hbv) است. محدودیتهای موجود در درمان hbv به همراه پیشرفتهایی که درزمینه بیولوژی مولکولی hbv اتفاق افتاده، تلاشها را برای کشف شیوههای جدید در مهار تکثیر hbv افزایش داده است. ژنوم بسیار فشرده و همپوشان با عملکردهای مختلف باعث شده تا hbv به عنوان یک هدف مناسب برای درمان بر پایه هیبریداسیون ا...
Hepatitis B infection is the main cause of liver related mortality in many countries including Iran. Liver transplantation in cirrhosis due to HBV infection before 1990 was an absolute contraindication. Recurrent infection was a significant event in post liver transplant setting and resulted in increased risk of graft failure and death except successful transplanted individuals. Advances in ant...
BACKGROUND There is little information about the effect of infliximab on the clinical course of liver disease in Crohn's disease patients with concomitant hepatitis B virus (HBV) infection. Theoretically, immunosuppression induced by infliximab will facilitate viral replication which could be followed by a flare or exacerbation of disease when therapy is discontinued. There are no specific reco...
Occult hepatitis B virus infection (OBI) is characterised by the persistence of hepatitis B virus (HBV) genome in the liver, without any evidence of overt infection: without HBV surface antigen (HBsAg) and HBV DNA detectable in the serum, or fugacious spots of very low levels of viraemia. OBI, a possible phase in the natural history of chronic hepatitis B, is mainly due to the strong suppressio...
BACKGROUND Chronic hepatitis B virus (HBV) infection is complicated by cirrhosis and liver cancer. In Thailand, 6-7 % of adults are chronically infected with HBV. The risk of mother-to-child transmission (MTCT) of HBV has been estimated to be about 12 % when mothers have a high hepatitis B viral load, even if infants receive passive-active prophylaxis with HBV immunoglobulin (HBIg) and initiate...
IMPORTANCE Hepatitis B virus (HBV) reactivation is a serious complication for patients with lymphoma treated with rituximab-containing chemotherapies, despite lamivudine prophylaxis treatment. An optimal prophylactic antiviral protocol has not been determined. OBJECTIVE To compare the efficacy of entecavir and lamivudine in preventing HBV reactivation in patients seropositive for the hepatiti...
