MORERA BARRIOS, Luz M et al. Frequency of HLA genes in patients with chronic kidney insufficiency, from western and central Cuba. Rev Cubana Hematol Inmunol Hemoter [online]. 2015, vol.31, n.1, pp. 32-40. ISSN 1561-2996.

Introduction: transplantation is the therapy allowing the highest possible survival in patients with chronic kidney insufficiency. To prevent rejection of the organ, first of all it is necessary to make a compatibility test of human leukocyte antigens (HLA) from the patient and the possible donors. In Cuba, only serological HLA typing had been made but at present, molecular techniques are being applied.  Aim:  characterization of polimorfirsm of alleles HLA A, B, DR y DQ by molecular techniques in Cuban patients awaiting renal transplantation. Methods: four hundred and ten patients with chronic kidney insufficiency from Western and Central Cuba were studied by molecular typing of the above mentioned loci.  Results were expressed by the new nomenclature and were registered In a data base prepared for that purpose.  Allele frequencies of white and no white population were compared and percentage of haplotype frequencies for alleles class I and II were determined. Results:  alleles A*11, A*30, A*74,  B*42, B*51and  B*53 were more frequent in white population while B*58 y DRB1*, 15 were mostly found in no whites.  Haplotypic frequencies most found in class I in white population were A*02 B*51, A*02 B*44, A*02 B*35; and in no whites,  A*01B*08, A*02B*51, A*02B*44.  For class II alleles, DQB1*03, DRB1*04, DQB1*06, DRB1*13, DRB1*05, DRB1*01 were the most found in white population; and in no whites, DQB1*03, DRB1*04, DQB1*06, DRB1*13, DQB1*05, DRB1*01. Conclusions:  characterization of patients with chronic kidney insufficiency in respect to HLA typing will allow future strategies related to kidney donation and transplantation in the whole country.
