CASE REPORT OF INFECTION BY AN OCCULT HBV CARRIER

Japanese Journal of Transfusion and Cell Therapy, 2006
2004年10月に医療機関から輸血後HBV感染が疑われる症例が報告された. この患者に輸血された33本全てについて個別核酸増幅検査 (個別NAT) を行ったところ, 一人の献血者から得られた血液が陽性と確認され, 患者と当該血液のHBV-DNA sequence はほぼ一致し, 因果関係が認められた. この献血者は, 54歳男性で過去11年間に78回の献血歴があり, HBs抗原陰性で個別NATが所々で陽性となる occult HBV carrier であった. 同献血者の血液は, 過去3回, 輸血後HBV感染の疑いとして報告された患者に使用されていた. 報告を受けた時点では, 個別NATが全て陰性であったため, 感染の因果関係が立証できなかった.

OCCULT HEPATITIS B VIRUS INFECTION AMONG BLOOD DONORS WITH ANTIBODIES TO HEPATITIS B CORE ANTIGEN [PDF]

Acta Medica Iranica, 2008
Diagnosis of hepatitis B is routinely based on of serological assay of hepatitis B surface antigen (HBsAg). Occult hepatitis B virus (HBV) infection is generally defined as the detection of HBV -DNA in the serum or tissues of subjects who have negative ...

Occult hepatitis B infection and its possible impact on chronic hepatitis C virus infection

The Saudi Journal of Gastroenterology, 2009
As a well-recognized clinical phenomenon, persistent detectable viral genome in liver or sera in the absence of other serological markers for active hepatitis B virus (HBV) replication is called occult HBV infection.

Prevalence and Temporal Trends of Transfusion‐Transmissible Infections Among Blood Donors in a Municipal Hospital in Navrongo, Ghana: A Retrospective Study (2018–2024)

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aim Blood transfusion is a vital and life‐saving procedure, saving millions of lives across the world every year. However, it also presents a significant risk of spreading transfusion‐transmissible infections (TTIs) such as hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency virus (HIV), and syphilis ...

Molecular analysis of hepatitis B virus (HBV) in an HIV co-infected patient with reactivation of occult HBV infection following discontinuation of lamivudine-including antiretroviral therapy

BMC Infectious Diseases, 2011
Background Occult hepatitis B virus (HBV) infection (OBI) is characterized by HBV DNA persistence even though the pattern of serological markers indicates an otherwise resolved HBV infection.

Occult hepatitis B infection: an evolutionary scenario

Virology Journal, 2008
Background Occult or latent hepatitis B virus (HBV) infection is defined as infection with detectable HBV DNA and undetectable surface antigen (HBsAg) in patients' blood. The cause of an overt HBV infection becoming an occult one is unknown.
