Prevalence of HBV DNA in anti-HBe+ chronic HBV carriers in Babol, 2002

Majallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2004
Background and Objective: One of the most important mutations, which occur in hepatitis B virus, is precore mutant. This mutation is associated with highly productive infection in anti-HBe+ chronic HBV carriers. These chronic HBV carriers are predisposed

HTLV screening and confirmatory testing among blood donors in São Paulo: A cross‐sectional study

Transfusion Medicine, EarlyView.
Abstract Introduction Human T‐cell lymphotropic virus types 1 and 2 (HTLV‐1/2) are transfusion‐transmissible retroviruses associated with severe diseases, and blood donor screening is mandatory in Brazil. Increasing HTLV‐related discard rates at our institution prompted this study to determine the prevalence and incidence of HTLV‐1/2 and to investigate

Identifying blood deserts in Liberia: A geospatial analysis

Transfusion, EarlyView.
Abstract Background Understanding patterns in blood availability is key to identifying appropriate interventions to increase blood access, particularly interventions intended for use in blood deserts, defined as areas in which >75% of blood needs are unmet.

Hepatitis B virus infection with high HBsAg and undetectable DNA levels in untreated blood donors: Viral mechanisms and transfusion safety implications

Transfusion, EarlyView.
Abstract Background Blood donor screening occasionally identifies individuals with high HBV surface antigen (HBsAg) levels despite undetectable or extremely low HBV DNA. Molecular basis and transfusion risk of this discordant profile remain unclear. Study Design and Methods Seventy‐five blood donors with HBsAg >100 IU/mL and undetectable or very low ...

Presence of HBV DNA in spermatozoa: a possible vertical transmission of HBV via the germ line.

, 1985
Using molecular hybridization we studied the presence and state of HBV DNA in sperm samples obtained from 17 patients with HBV infection (eight HBsAg chronic carrier, nine acute hepatitis B).

Budget impact of implementing universal Plasmodium NAT screening in the blood transfusion system in the US

Transfusion, EarlyView.
Abstract Background Blood donor deferral for malaria risk relies exclusively on responses to self‐reported questionnaires. This study evaluated the economic impact of introducing Plasmodium nucleic acid testing (NAT) as a universal screening strategy in the United States.

Long‐term stability and reproducibility of frozen plasma control samples for hepatitis B virus, hepatitis C virus, and human immunodeficiency virus by quantitative PCR: Implications for retrospective testing in hemovigilance

Transfusion, EarlyView.
Abstract Objective Data on the long‐term stability and reproducibility of nucleic acid amplification testing (NAT) results in frozen stored positive samples (≤−20°C) remain limited. This study evaluated the long‐term performance of frozen virus‐positive samples in quantitative PCR assays and aimed to provide evidence for their analytical reliability in

Evaluation of a new random-access HBV DNA molecular assay: The VERIS HBV assay.

, 2017
International audienceDetection and quantification of HBV DNA are essential to diagnose chronic HBV infection, monitor the virological response to treatment and the possible selection of resistant viruses in order to tailor therapy.
