Frozen maternal platelets for neonatal thrombocytopenia
Transfusion
|July 1, 1987
Summary
Maternal platelets, cryopreserved for 3 months, were successfully used to treat neonatal thrombocytopenia. This approach avoided immediate maternal platelet collection, offering a viable transfusion option for alloimmunized infants.
Area of Science:
- Neonatal Medicine
- Hematology
- Immunology
Background:
- Neonatal thrombocytopenia poses significant risks, especially in alloimmunized infants.
- Maternal platelet transfusion is a potential treatment but often requires immediate collection, posing logistical challenges.
Observation:
- A case of an alloimmunized, neonatal, thrombocytopenic patient is presented.
- Maternal platelets were collected via cytapheresis and cryopreserved 3 months prior to delivery.
Findings:
- Successful transfusion of cryopreserved maternal platelets was achieved over a 7-day period.
- The transfusion provided an average of 7.1 X 10(10) platelets per aliquot.
- Sustained satisfactory increases in the infant's platelet counts were observed post-transfusion.
Implications:
- Cryopreservation of maternal platelets offers a practical alternative to immediate collection for treating neonatal thrombocytopenia.
- This method can be beneficial for alloimmunized neonates, ensuring timely and effective platelet support.
- Avoids the need for immediate maternal phlebotomy or cytapheresis around delivery.
