Occult hepatitis B infection and HBV replicative activity in patients with cryptogenic cause of hepatocellular carcinoma.
UNLABELLED We aimed to investigate the incidence of occult hepatitis B infection (OBI) in patients with "cryptogenic" hepatocellular carcinoma (HCC) and to study the HBV replicative activity in these patients. Tumorous and adjacent nontumorous liver tissues were obtained from 33 cryptogenic HCC patients and 28 HCC patients with identifiable causes (13 with chronic hepatitis B [CHB], six with ch...
متن کاملOccult HBV infection among a cohort of Nigerian adults.
OBJECTIVE To determine markers of HBV infection and detect the presence of its occult infection in serum of a cohort of adult Nigerians. METHODOLOGY The study involved 28 adult Nigerians with viral hepatitis (Group 1) and 28 apparently healthy adult Nigerians as controls (Group 2). Their sera were assayed for HBsAg, HBeAg, anti-HBe, anti-HBc, anti-HBs, and anti-HCV, while HBV DNA was determin...
متن کاملIsolated Anti-HBc and Occult HBV Infection in Dialysis Patients
BACKGROUND Occult Hepatitis B virus (HBV) infection (OBI) is defined as the presence of HBV-DNA in the liver or serum with undetectable hepatitis B surface antigen (HBsAg). Hemodialysis (HD) patients are at risk of acquiring parenterally transmitted infections. OBJECTIVES The aim of this study was to assess the prevalence of OBI in HD patients. PATIENTS AND METHODS A hundred HBsAg negative ...
متن کاملThe clinical significance of occult HBV infection
The presence of hepatitis B virus (HBV) DNA in HBV surface antigen (HBsAg)-negative individuals is defined as occult HBV infection (OBI). OBI is related in some cases to infection with variant viruses (S-escape mutants) undetectable by HBsAg commercial kits. More frequently, however, it is due to infection with wild-type viruses that are strongly suppressed in their replication activity. OBI ma...
متن کاملHBV vaccination of HCV-infected patients with occult HBV infection and anti-HBc-positive blood donors.
Anti-HBc positivity is a frequent cause of donation rejection at blood banks. Hepatitis B virus (HBV) infection may also occur in HBsAg-negative patients, a situation denoted occult infection. Similarly, very low levels of HBV-DNA have also been found in the sera of patients with chronic hepatitis C virus (HCV) infection, even in the absence of serum HBsAg. Initially we searched for HBV-DNA in ...
