Stem Cells and Artificial Substitutes Could Ease the Dependence on Blood Donations
OUTLOOK BLOOD DOING WITHOUT DONORS Stem cells and artificial substitutes could ease the dependence on blood donations. ANDREW BAKER BY ELIE DOLGIN S12 | NATURE | VOL 549 | 28 SEPTEMBER©2017 Ma c2017millan Publishers Li mited, part of Spri nger Nature. All ri ghts reserved. ©2017 Mac millan Publishers Li mited, part of Spri nger Nature. All ri ghts reserved. BLOOD OUTLOOK ach year, at about 13,000 collection centres worldwide, phlebotomists stick needles in the veins of healthy vol- unteers and amass in excess of 110 million donations of blood. The volume collected is enough to fill 20 Olympic- sized swimming pools — but it’s nowhere near to meeting the medical demand for whole blood or its components. To fill the gap, an enterprising group of stem-cell biologists and bio- Eengineers hopes to produce a safe, reliable and bottomless supply of on-demand blood substitutes in the laboratory. According to Robert Lanza, a pioneer of stem cell therapies and head IMAGES IWM VIA GETTY CHETWYN/ SGT. of global regenerative medicine at Astellas Pharma in Marlborough, Massachusetts, current technologies are not yet ready to compete with the real stuff. “We’re not going to put blood banks out of business any time soon,” he says. But in the near future, artificial blood products could be approved for use when transfusions are not otherwise an option, such as during combat or in people with a religious objection to receiving blood transfusions. And therapies that rely on reprogrammed stem cells to produce components of blood might also help transfusion centres to relieve shortages or to avoid donor-derived contamination. -
Blood Product Replacement: Obstetric Hemorrhage
CMQCC OBSTETRIC HEMORRHAGE TOOLKIT Version 2.0 3/24/15 BLOOD PRODUCT REPLACEMENT: OBSTETRIC HEMORRHAGE Richard Lee, MD, Los Angeles County and University of Southern California Medical Center Laurence Shields, MD, Marian Regional Medical Center/Dignity Health Holli Mason, MD, Cedars-Sinai Medical Center Mark Rollins, MD, PhD, University of California, San Francisco Jed Gorlin, MD, Innovative Blood Resources/Memorial Blood Center, St. Paul, Minnesota Maurice Druzin, MD, Lucile Packard Children’s Hospital Stanford University Jennifer McNulty, MD, Long Beach Memorial Medical Center EXECUTIVE SUMMARY • Outcomes are improved with early and aggressive intervention. • Both emergency blood release and massive transfusion protocols should be in place. • In the setting of significant obstetric hemorrhage, resuscitation transfusion should be based on vital signs and blood loss and should not be delayed by waiting for laboratory results. • Calcium replacement will often be necessary with massive transfusion due to the citrate used for anticoagulation in blood products. • During massive transfusion resuscitation, the patient’s arterial blood gas, electrolytes, and core temperature should be monitored to guide clinical management and all transfused fluids should be warmed; direct warming of the patient should be initiated as needed to maintain euthermia and to avoid added coagulopathy. BACKGROUND AND LITERATURE REVIEW After the first several units of packed red blood cells (PRBCs) and in the face of continuing or worsening hemorrhage, aggressive transfusion therapy becomes critical. This report covers the experience with massive transfusion protocols. Lessons from military trauma units as well as civilian experience with motor vehicle accidents and massive obstetric hemorrhage have identified new principles such as earlier use of plasma (FFP/thawed plasma/plasma frozen within 24 hours/liquid plasma) and resuscitation transfusion while laboratory results are pending. -
Platelet-Rich Plasmapheresis: a Meta-Analysis of Clinical Outcomes and Costs
THE jOURNAL OF EXTRA-CORPOREAL TECHNOLOGY Original Article Platelet-Rich Plasmapheresis: A Meta-Analysis of Clinical Outcomes and Costs Chris Brown Mahoney , PhD Industrial Relations Center, Carlson School of Management, University of Minnesota, Minneapolis, MN Keywords: platelet-rich plasmapheresis, sequestration, cardiopulmonary bypass, outcomes, economics, meta-analysis Presented at the American Society of Extra-Corporeal Technology 35th International Conference, April 3-6, 1997, Phoenix, Arizona ABSTRACT Platelet-rich plasmapheresis (PRP) just prior to cardiopulmonary bypass (CPB) surgery is used to improve post CPB hemostasis and to minimize the risks associated with exposure to allogeneic blood and its components. Meta-analysis examines evidence ofPRP's impact on clinical outcomes by integrating the results across published research studies. Data on clinical outcomes was collected from 20 pub lished studies. These outcomes, DRG payment rates, and current national average costs were used to examine the impact of PRP on costs. This study provides evidence that the use of PRP results in improved clinical outcomes when compared to the identical control groups not receiving PRP. These improved clinical out comes result in subsequent lower costs per patient in the PRP groups. All clinical outcomes analyzed were improved: blood product usage, length of stay, intensive care stay, time to extu bation, incidence of cardiovascular accident, and incidence of reoperation. The most striking differences occur in use of all blood products, particularly packed red blood cells. This study provides an example of how initial expenditure on technology used during CPB results in overall cost savings. Estimated cost savings range from $2,505.00 to $4,209.00. -

Important Information for Female Platelet Donors
Important Information for Female Platelet Donors We are grateful for the support you provide our community blood program and especially appreciate your willingness to help save lives as a volunteer platelet donor. We also take our responsibility to provide a safe and adequate blood supply very seriously and need to share the following information regarding a change to our donor eligibility criteria for female platelet donors. We recently began performing a Human Leukocyte Antigen (HLA) antibody test on each of our current female platelet donors who have ever been pregnant. In addition, we modified our Medical History Questionnaire to ask donors whether they have been pregnant since their last donation. Platelet donors who respond yes to that question will be screened for HLA antibodies. Platelet donors will also be retested after every subsequent pregnancy. These adjustments are being made as part of our effort to reduce occurrences of Transfusion-Related Acute Lung Injury (TRALI). TRALI is a rare but serious complication of blood transfusions most commonly thought to be caused by a reaction to HLA antibodies present in the donor’s plasma. When transfused, these antibodies can sometimes cause plasma to leak into the patient’s lungs, creating fluid accumulation — a condition referred to as acute pulmonary edema. Female donors who have been pregnant are more likely than others to have these HLA antibodies in their plasma. Once the antibodies develop, they are present forever. The antibodies could be harmful if transfused into certain patients. The antibodies are present in plasma — and platelet donations contain a high volume of plasma, so our current efforts are directed at screening blood samples from female platelet donors to test for the HLA antibody. -

FDA Regulation of Blood and Blood Components in the United States
FDA Regulation of Blood and Blood Components in the United States SLIDE 1 This presentation will review the FDA Regulation of Blood and Blood Components in the U.S. SLIDE 2 The FDA Center for Biologics Evaluation and Research, or CBER, Office of Blood Research and Review, called OBRR, reviews several different types of regulatory applications with respect to blood and blood components. This includes biologics license applications, called BLAs, which represent the regulatory pathway for blood components. The BLA regulatory process also applies to biological drugs such as fractionated plasma products. OBRR also regulates in-vitro diagnostic devices used for screening of collected blood, and does so also using the BLA regulatory pathway. Review of these devices as biologic licenses allows CBER to apply a higher level of manufacturing oversight, including lot release testing and pre-licensure inspection. This regulatory pathway applies to infectious disease tests for blood screening, as well as blood grouping and phenotyping reagents. SLIDE 3 The regulatory pathway for New Drug Applications, or NDAs, is most commonly used within the Center for Drug Evaluation and Research, or CDER. Within the Office of Blood, several NDA applications are reviewed each year, mostly involving solutions used for the collection of blood, such as anticoagulants and red cell nutritive solutions. Interestingly, a blood bag that does not have a solution inside is regulated as a device. If the bag has a solution, then it is a drug-device combination product, but is regulated as a drug. SLIDE 4 OBRR reviews both Class Two and Class Three devices. Class Three devices in OBRR include diagnostic tests for HIV regulated as pre-market approvals, called PMAs. -
