Pretransplant RBC Alloimmunization Is Risk Factor for Poor Outcome After HCT in SCD The current study explored whether RBC alloimmunization prior to HCT is linked to post-transplant outcomes and the need for transfusion support.

In pediatric patients with sickle cell disease (#SCD), red blood cell (#RBC) alloimmunization is a significant risk factor for a poor outcome following hematopoietic cell transplantation (#HCT).

Recognizing Rare Blood Group Mismatches Important for Diagnosing HDFN In neonates who present with unexplained anemia and hyperbilirubinemia, immunohematologic evaluation is key for diagnosing possible HDFN.

Among neonates who present with unexplained #Anemia and #Hyperbilirubinemia, individualized immunohematologic evaluation is essential for diagnosing hemolytic disease of the fetus and newborn (#HDFN). Published in @cureusmedical.bsky.social

So, does the protocol work?

In the 5-year quality assessment, 1,926 RhD – packed blood components were saved

Only 22.2% of patients had Anti-D development due to the recipients in the study being immunosuppressed.

HDFN Risk May Be Reduced With Standardized RBC Antibody Reporting An unmet, critical need exists to standardize RBC antibody reporting practices among laboratories and thus reduce the overall risk for HDFN.

Case Report: Additional Antibodies Following Intrauterine Transfusion A 24-year-old pregnant patient developed additional alloantibodies following IUT, leading to the need for tailored management, according to a case report.

Intrauterine transfusion (#IUT) is a key intervention in hemolytic disease of the fetus and newborn (#HDFN), but clinicians must be vigilant about the risk of maternal sensitization and alloantibody development.

Neonatal Exchange Transfusions Decline in Serbia, Anti-D Alloimmunization Persists Neonatal exchange transfusions in Serbia have declined over 23 years, yet anti-D alloimmunization in RhD-negative mothers, a key cause of HDFN, persists.

#HDFN remained the leading indication for exchange transfusion, accounting for 67% of cases, primarily driven by anti-D alloimmunization (65.9%).

Coordinated Strategy Needed in Pregnancies Complicated by Antibodies Unique challenges are associated with pregnancies complicated by the development of antibodies to high-prevalence Rh blood group antigens.

A multidisciplinary, coordinated approach is called for in pregnancies that present with antibodies to high-prevalence blood group antigens and might result in hemolytic disease of the fetus and newborn (#HDFN). Case study in Transfusion @aabbupdates.bsky.social

James Harrison, whose blood donations saved over 2 million babies, has died Harrison, whose plasma contained a rare antibody, rolled up his sleeve 1,173 times from 1954 to 2018. The Australian is credited with helping 2.4 million babies and advancing scientific research.

James Harrison is credited with saving the lives of 2.4 million babies. His plasma contained a rare antibody called anti-D, which is used in medications to prevent haemolytic disease of the fetus & newborn #HDFN, aka #RhesusDisease, a potentially dangerous disease for unborn babies.

Clinical Trial Shows Promise for HDFN A new era of treatment thanks to new drug nipocalimab.

Through a clinical trial of the drug nipocalimab, physicians at Children's Colorado are ushering in a new era of treatment for patients with hemolytic disease of the fetus and newborn (HDFN), a major step forward in #HDFN care. #NeoSky
