Apheresis technology correlates with bacterial contamination of platelets and reported septic transfusion reactions.

Background: Apheresis technology to collect platelet (PLT) components differs among devices. We evaluated the relationship of the plateletpheresis device with bacterial contamination and reported septic transfusion reactions.

Study Design And Methods: Plateletpheresis was performed using Amicus (Fenwal, a Fresenius Kabi Company) or Trima (Trima Accel, TerumoBCT) from 2010 to 2014.

Per- and polyfluoroalkyl substances (PFAS) in American Red Cross adult blood donors, 2000-2015.

In 2015, thirteen per- and polyfluoroalkyl substances (PFAS), including perfluorohexanesulfonate (PFHxS), perfluorooctanesulfonate (PFOS), perfluorooctanoate (PFOA), perfluorononanoate (PFNA), and perfluorodecanoate (PFDA) were analyzed in human plasma that were collected from a total of 616 American Red Cross male and female blood donors (ages 20-69) at 6 regional blood collection centers. Plasma samples were analyzed using a validated solvent precipitation-isotope dilution direction-liquid chromatography tandem mass spectrometry method. The data were analyzed in conjunction with prior cross-sectional investigations [2000-2001 (n =645), 2006 (n =600), and 2010 (n =600)] to determine PFAS trends.

A probable case of West Nile virus transfusion transmission.

Background: Transfusion-transmitted West Nile virus (WNV) infection is infrequent as a result of minipool (MP) and individual-donation (ID) nucleic acid testing (NAT) of blood donations. ID-NAT is triggered on the basis of local WNV activity identified by MP-NAT.

Study Design And Methods: A 78-year-old male patient who was treated for cardiac disease received 14 blood components from 30 donors in August 2016.

Temporal trends of perfluoroalkyl concentrations in American Red Cross adult blood donors, 2000-2010.

Eleven perfluorinated alkyl acids (PFAAs) were analyzed in plasma from a total of 600 American Red Cross adult blood donors from six locations in 2010. The samples were extracted by protein precipitation and quantified by using liquid chromatography tandem mass spectrometry (HPLC/MS/MS). The anions of the three perfluorosulfonic acids measured were perfluorobutane sulfonate (PFBS), perfluorohexane sulfonate (PFHxS), and perfluorooctane sulfonate (PFOS).

The third described case of transfusion-transmitted Babesia duncani.

Background: Almost all of the reported US tick-borne and transfusion-associated Babesia cases have been caused by Babesia microti, which is endemic in the Northeast and upper Midwest. We investigated a case caused by B. duncani (formerly, the WA1-type parasite), in a 59-year-old California resident with sickle cell disease (HbSS) whose only risk factor for infection was receipt of red blood cell transfusions.

Analysis of a homologous series of perfluorocarboxylates from American Red Cross adult blood donors, 2000-2001 and 2006.

The purpose of this study was to determine the concentration trends of a nine-target-analyte homologous series of perfluorocarboxylates from six American Red Cross adult blood donor centers. A total of 645 serum and 600 plasma samples were obtained in 2000-2001 and 2006, respectively, with samples stratified for each 10-year (20-69) age- and sex-group per each location. Samples were extracted by protein precipitation and quantified by using tandem mass spectrometry.

Donor survey to assess facial flushing during automated red cell collections and medication use.

Background: We conducted a donor survey to assess the occurrence of facial flushing and other symptoms during automated 2-U red cell collections (2RBC) and plateletpheresis (PLT) procedures and evaluated the possible association of the reactions with angiotensin-converting enzyme (ACE) inhibitors or with the collection technology.

Methods: An online survey was developed using Zoomerang to capture details of the donors' experience and medication use after 2RBC or PLT donations in regional blood centers of the American Red Cross.

Results: Between 12/16/09 and 4/19/10, 1,299 donors in five American Red Cross blood center regions completed an online survey (739 2RBC, 4.

Effective reduction of transfusion-related acute lung injury risk with male-predominant plasma strategy in the American Red Cross (2006-2008).

Background: Plasma components from female donors were responsible for most cases of transfusion-related acute lung injury (TRALI) reported to the American Red Cross (ARC) between 2003 and 2005. Consequently, we began preferentially distributing plasma from male donors for transfusion in 2006 and evaluated the effect on reported TRALI cases in the ensuing 2 years.

Study Design And Methods: Suspected TRALI cases reported to the ARC Hemovigilance Program in calendar years (CY) 2006, 2007, and 2008 are described.

Decline in perfluorooctanesulfonate and other polyfluoroalkyl chemicals in American Red Cross adult blood donors, 2000-2006.

In 2000, 3M Company, the primary global manufacturer, announced a phase-out of perfluorooctanesulfonyl fluoride (POSF, C8F17SO2F)-based materials after perfluorooctanesulfonate (PFOS, C8F17SO3-) was reported in human populations and wildlife. The purpose of this study was to determine whether PFOS and other polyfluoroalkyl concentrations in plasma samples, collected in 2006 from six American Red Cross adult blood donor centers, have declined compared to nonpaired serum samples from the same locations in 2000-2001. For each location, 100 samples were obtained evenly distributed by age (20-69 years) and sex.

Trypanosoma cruzi parasitemia in US blood donors with serologic evidence of infection.

Trypanosoma cruzi infection (which causes Chagas disease) is typically undiagnosed and persists if untreated. We sought to affirm that T. cruzi-seropositive US blood donors have persistent infection with demonstrable parasitemia long after acquisition of infection.

Perfluorooctanesulfonate and other fluorochemicals in the serum of American Red Cross adult blood donors.

Perfluorooctanesulfonyl fluoride-based products have included surfactants, paper and packaging treatments, and surface protectants (e.g., for carpet, upholstery, textile).

Trypanosoma cruzi in Los Angeles and Miami blood donors: impact of evolving donor demographics on seroprevalence and implications for transfusion transmission.

Background: Trypanosoma cruzi, the agent of Chagas' disease, continues to be a concern for blood safety, as demonstrated by recent transfusion-transmitted cases in the United States and Canada. The chronic nature of Chagas', coupled with increasing numbers of immigrants from T. cruzi-endemic countries, suggests that Chagas' is a long-term public health problem.
