Selecting red blood cells for patients with hemoglobinopathies

Why did ICTMG develop a guideline for hemoglobinopathies?

Red blood cell transfusions are a life-sustaining therapy for patients with β-thalassemia or sickle cell disease, but having multiple transfusions puts them at high risk for alloimmunization.  Alloimmunization is a well-documented complication of transfusion that increases the risk of delayed hemolytic transfusion reactions, complicates crossmatching and identifying compatible units, and delays provision of transfusions.

ICTMG's recommendations can help ensure these transfusion patients receive the red cell blood product that is optimal for them.  The guideline is intended for transfusion medicine physicians as well as physicians intending to transfuse patients with hemoglobinopathies and apply to patients who require chronic or isolated red blood cell transfusion.

How to access the ICTMG publication

ICTMG's systematic review and guideline on transfusing red blood cells for patients with hemoglobinopathies was published in Transfusion in 2018:

The best match - Transfusing patients with hemoglobinopathies

Listen to Dr. Shubha Allard, consultant hematologist, in conversation with Dr. Stella Chou, pediatric hematologist and transfusion medicine specialist, and Dr. Gregory Denomme, clinical scientist.

They discuss red cell matching strategies for patients with hemoglobinopathies: the evidence for selecting antigen-matched red blood cells, matching in resource-limited settings, and how ICTMG’s recommendations can help standardize transfusion practices.

Hemoglobinopathies algorithm

Print out the decision-making algorithm summarizing ICTMG’s recommendations for red blood cell transfusion in patients with sickle cell disease and thalassemia syndromes. It can be used by health-care professionals involved in transfusion of patients, clinicians, medical directors of transfusion labs, and medical technologists who provide blood products in hospitals.

International reach

The ICTMG guideline on red cell matching strategies are helping to standardize transfusion practices and optimize outcomes for patients with sickle cell disease and thalassemia syndromes. Check out how the guideline is being used or adapted in different countries.

American Society of Hematology

In July 2019, the American Society of Hematology (ASH) affirmed that ICTMG’s guidelines have value for hematologists. Read the ASH statement here:
