[HLA antigen compatibility between patients with hematologic diseases and their parents].

| Abstract |
This study was aimed to investigate and analyze the HLA antigen compatibility between patients with hematologic diseases and their parents so as to provide basis for selecting the suitable donors in haploidentical hematopoietic stem cell transplantation. The HLA low resolution for 174 families was typed and analyzed by using PCR-SSP. The results showed that 52.30% of patients with hematologic diseases possessed father and/or mother with HLA matching over haploidentity, 10.92% patients were over 8/10 matched with their father and/or mother. 11.49% were over semi-matched with both their father and mother. The rate of 6/10 matched pairs (28.16%), 7/10 matched pairs (16.1%) and 8/10 matched pairs (8.62%) were all beyond 5%; 9/10 (2.3%) and 10/10 matched pairs (1.15%) were all below 5%. It is concluded that with the matching degree increasing between two generations, HLA matching rate is decreasing. Over 50% and 10% patients were over HLA semi-matched and 8/10 matched with their father and/or mother, respectively. This high matching rate offered a big chance for success of haploidentical HSCT. Patients are more likely over semi-matched with their father and/or mother when they have high frequency and strong linkage HLA disequilibrium. High frequency and strong linkage disequilibrium in populations are main reason, and population concentrating and isolated living may be another reason for this phenomenon.
