Establishment and capacity analysis of Hefei platelet donor bank with HPA and HLA high-resolution results
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 11
Abstract
Objective To establish a platelet donor database with HPA and HLA high resolution results in Hefei area, and to analyze the appropriate pool capacity, so as to provide support for patients with immune PTR transfusion difficulties. Methods The HPA-1-6, -10, -15 and 21 genotypes of 1157 voluntary blood donors in Hefei were analyzed by multiplex PCR and the frequencies were calculated. HLA-A, -B high resolution gene frequency and haplotype frequency in 1115 voluntary blood donors in Hefei were calculated using maximum expected value method. Results Hefei database of platelet donors was established according to the analysis of HPA and HLA high-resolution gene polymorphisms in Hefei population.In the donor pool with 1 157 cases of known genotypes HPA-1-6, -10, -15, -21, about 91% of patients can find an donor with full-matched HPA genotype. In the donor pool with 1 115 cases of known HLA-A, -B high-resolution genotype, the probability of finding at least one identical donor is about 60%. Conclusion The local-suitable database of platelet donors with known HPA and HLA genotypes in Hefei has been established. After analysis, this database basically meets the needs of patients with immune PTR to find suitable platelets.
