International Society of Blood Transfusion (ISBT) shared a post on LinkedIn about a recent article by Lucile Malard et al. published in Vox Sanguinis:
“Recently published in Vox Sanguinis
Association between group B major ABO-incompatible platelet or plasma transfusion and severe allergic reactions: A nationwide haemovigilance analysis suggesting a role for α-gal syndrome.
Key takeaways:
- Transfusing group B or AB platelets/plasma to group O recipients in France is linked to higher risk of severe allergic transfusion reactions (ATR).
- The risk is stronger with platelet transfusions than plasma, possibly related to α-gal syndrome.
- Recommendation: Group O recipients should receive ABO-identical platelets or plasma whenever possible.
A step forward in safer, personalized transfusion care.”
