1942 Emerging Infectious Diseases • www.cdc.gov/eid • Vol. 20, No. 11, November 2014 restricted to plasma for fractionation. Some protection against blood donations from HEV-infected persons may occur because HEV and malaria are coendemic to many countries. Our findings showed a higher HEV seroprevalence among donors with prior malaria or diarrhea deferrals; thus, malariaand diarrhea-related sc...
Background/Aim. Plasma containing a high titer of anti-SARS-CoV-2 antibodies, donated from individuals who recovered COVID-19, has the potential to be used as initial therapy for patients have been infected (passive immunization). It is challenge find suitable donors. The aim study was successively monitor antibody in donations and investigate correlation between severity clinical manifestation...
Strategies implemented to prevent transmission of infections by blood transfusion have been very successful. Despite this, the risk of infectious donations entering the blood supply and transmitting infection to the recipients of blood components and blood products is continually under scrutiny. In order to assess the risks and consequences of transfusion transmitted infections the characterist...
Following reports of West Nile neuroinvasive disease in the north-eastern area of Italy in 2009, all blood donations dating from the period between 1 August and 31 October 2009 in the Rovigo province of the Veneto region were routinely checked to exclude those with a positive nucleic acid test for West Nile virus (WNV). Only one of 5,726 blood donations was positive (17.5 per 100,000 donations;...
OBJECTIVE The effects of C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) on pregnancy-associated plasma protein-A (PAPP-A) expression in human peripheral blood mononuclear cells (PBMCs) require further investigation. METHODS The PAPP-A levels in culture supernatants, PAPP-A mRNA expression, and cellular PAPP-A expression were measured in human PBMCs isolated from fresh blood dona...
Human immunodeficiency virus type 1 (HIV-1) can be transmitted through breast-feeding and through contaminated blood donations. Copper has potent biocidal properties and has been found to inactivate HIV-1 infectivity. The objective of this study was to determine the capacity of copper-based filters to inactivate HIV-1 in culture media. Medium spiked with high titers of HIV-1 was exposed to copp...
This is the first empirical investigation of blood donations in evolutionary perspective. We examine blood donor and non-donor attitudes about health and injury risks, donor characteristics, and the social value of donor participation. We propose that blood donations may communicate qualities about donors to third parties. Observers may benefit from information about the donor’s health, value a...
abstract human blood and blood products is the source of a wide range of medicinal products used for the treatment and prevention of a variety of injuries and disease. despite stringent routine measures and filters employed, residual pathogen infectivity remains an important challenge in the field of blood transfusion. in this article various measures and technologies that can be applied in ord...
