Occult Hepatitis B Infection in Recent Immigrants to Italy: Occult B Infection in Immigrants
Journal of Community Health, 2019This study determined the prevalence and clinical features of occult hepatitis B infection (OBI) in a population of recent immigrants to Italy. Two hundred-five immigrants were tested for HBV-infection and were classified as seropositive-OBI or false-OBI.

Indomethacin and Occult Infections
JAMA: The Journal of the American Medical Association, 1979To the Editor.— I recently read the article by Joe G. Hardin, MD (240:1889,1978), in which he described a man with long-standing Still's disease and aProteus mirabilisarthritis of the hip. Despite appropriate antibiotic therapy and no symptoms suggestive of a continued pyarthrosis, he still had the same organism in the hip six months later at the time

Occult hepatitis B virus infection
Journal of Hepatology, 2007The persistence of hepatitis B virus (HBV) genomes in HBV surface antigen (HBsAg) negative individuals is termed occult HBV infection. Occult HBV status is associated in some cases with mutant viruses undetectable by HBsAg assays, but more frequently it is due to a strong suppression of viral replication and gene expression.

Occult tuberculous infection in children
Tubercle, 1977Three hundred and fifty New Zealand children with occult tuberculous infection are reviewed. Ninety four had received BCG vaccine previously. Three hundred and forty were admitted to hospital and 3 gastric aspirations were obtained from each child and cultured for tubercle bacilli. Mycobacterium tuberculosis was isolated from 1 or more aspirates in 29 (

Occult infections of ventriculoatrial shunts
Journal of Neurosurgery, 1970✓ Organisms usually considered nonpathogens have been implicated with increasing frequency as the cause of infected ventriculoatrial shunts. Often the signs of infection are minimal, with no evidence of inflammation; but there may be low-grade fever, anemia, leukocystosis, and variably present hepatosplenomegaly.

Clinical impact of occult HBV infections
Journal of Clinical Virology, 2005HBV infection in the absence of HBsAg has been a matter of debate for years, but its existence and clinical relevance are now supported by many publications, editorials and reviews. HBV DNA without HBs antigenemia was detected in the following clinical situations: (1) Chronic, presumably viral, hepatitis unrelated to HCV, atypical alcoholic hepatitis ...

Occult HBV infection in the oncohematological setting
Infection, 2016Occult hepatitis B infection (OBI), a virological condition characterized by a low release of Hepatitis B Virus (HBV) from liver cells and low HBV-DNA levels in serum and/or liver tissue of HBsAg-negative subjects, may reactivate in oncohematological patients undergoing immunosuppression by aggressive chemotherapy or hematopoietic stem cell ...

Occult hepatitis B and HIV infection
European Journal of Gastroenterology & Hepatology, 2019Introduction Occult hepatitis B virus (HBV) infection, so-called occult B infection (OBI), is defined by the recognition of HBV-DNA in the absence of serum hepatitis B surface antigen (HBsAg). The HBV-DNA genome in OBI is fully replication competent and produced in the liver, characteristically with low-level HBV-DNA ...

A 2010 update on occult hepatitis B infection
Pathologie Biologie, 2010Occult hepatitis B virus infection is a challenging issue whose virological and clinical relevance has been a source of long-lasting debate. By definition, OBI is characterized by the persistence of HBV-DNA in the liver tissue (and in some cases also in the serum) in absence of HBsAg.

Occult hepatitis B virus infection
Transfusion Clinique et Biologique, 2004The detection of HBV DNA without HBsAg with or without the presence of HBV antibodies outside the acute phase window period defines occult HBV infection. This condition has been described in hepatocellular carcinoma (HCC), chronic hepatitis B, healthy HBV carriage and recovered infection, chronic hepatitis C and individuals without serological markers ...
