26 June 2023 (Monday) - Transfusion News Update

 

The nice people at Transfusion News sent their update today. Again tranexamic acid appears. And the article on alloimmunization was thought-provoking. Why do some people create antibodies after a single transfusion and others have (literally) gallons and create none?
 
Long-term Survival of Severe Trauma Patients Treated with Tranexamic Acid

June 21, 2023
Globally, trauma is the leading cause of death for young people. In 2011, the World Health Organization added tranexamic acid to the Model List of Essential Medicines for the treatment of trauma based on randomized trial data showing that tranexamic acid reduces mortality of hemorrhaging trauma patients.

Register for the new Transfusion Science Webinar to learn about Phenotype/Genotype Discrepancies, Their Cause, Importance, and Safe Resolution

Hemagglutination methods have been used over a century to determine blood group phenotypes. Serology cannot be used in some situations, leading laboratories to use molecular assays to predict red blood cell (RBC) phenotypes. Sometimes the predicted phenotype does not fit with the patient’s known antibodies or serological phenotype. These phenotype/genotype discrepancies can lead to confusion for laboratory and clinical staff. This can cause anxiety, delays in patient care, or even incorrect conclusions and inappropriate clinical advice and patient care. Shane Grimsley (DipRCPath) will explore some common discrepancies, detailing their causes and how to safely investigate them. This information will provide clues for resolving these issues and ensuring timely and accurate patient care. Join us on June 27th and 30th by registering for this webinar.

Intracellular RBC Antigens Can Enhance RBC Alloimmunization in Mice

June 14, 2023
RBC alloimmunization from transfusions or pregnancy can be life threatening. Currently, scientists have identified 43 polymorphic RBC surface antigen systems, and some are more immunogenic than others. Furthermore, there is a poor understanding of why most patients do not develop alloantibodies and why others respond to one or several antigens. [Read More]
 

12 June 2023 (Monday) - Transfusion News Update

 

The Transfusion News update came today… perhaps a tad too American in its outlook for me? But it is all good stuff…

Expanding U.S. Platelet Supply Needed

June 7, 2023 About 2.5 million units of platelets are transfused each year in the U.S., and data from the National Blood Collection and Utilization survey show a 16% increase in platelet transfusions and a 2% decrease in collections between 2017 and 2019. In 2019, approximately 40% of U.S. hospitals indicated that they routinely had platelet supply issues causing delays in surgeries and transfusions. [Read more]

 

Randomized Trial of Platelet Transfusions and Risk of Bleeding before CVC Placement

May 31, 2023About 18% of all hospitalized patients require central venous catheters (CVC) and is even more common on hematology wards and intensive care units (ICU) where patients often have thrombocytopenia. The AABB clinical practice guideline provides a weak recommendation that a minimum platelet count of 20,000 per cubic millimeter is needed before CVC placement. [Read more]
