Abstract
Background
Due to the presence of platelet antigen polymorphisms, human platelet membrane glycoproteins can be identified as an alloantigen or autoantigen. The aim of this study was to determine the frequencies of human platelet antigens (HPAs)-1 to-5 and-15 in Turkmen blood donors and establish a panel of accredited HPAs negative donors as well as an HPA-typed platelet donor registry.
Materials and Methods
HPA-1 to-5 and-15 typing was performed by the polymerase chain reaction-sequence-specific primer techniques on 80 unrelated Turkmen donors who were referred to Aq-Qala Blood Transfusion Center in Golestan Province from September 2018 to October 2019.
Results
The frequencies of HPA phenotypes were determined as follows: HPA-1aa: 92.5%, HPA-1ab: 7.5%, HPA-2aa: 77.5%, HPA-2ab: 20.0%, HPA-2bb: 2.5%, HPA-3aa: 75.3%, HPA-3ab: 50%, HPA-3bb: 11.2%, HPA-4aa: 100%, HPA-5aa: 78.5%, HPA-5ab: 21.5%, HPA-15aa: 41.2%, HPA-15ab: 56.2% and HPA-15bb: 17.5%.
Conclusion
Determining the genotype of HPAs that play an important role in platelet refractory can improve the management of alloimmunization due to the incompatibility of HPAs between the recipients and donors. Therefore, the registration process for national platelet donors can help patients accelerate and improve the quality of transfused platelets.
