Background: Renal transplant is the best Kidney replacement therapy to reduce morbidity and mortality in patients with end-stage chronic kidney disease. Knowing Human Leukocyte Antigen (HLA) typing and compatibility between donor and recipient decreases the risk of an alloimmune reaction. Objective: To determine the frequency and allelic HLA compatibility in pediatric patients undergoing kidney transplantation at the National Hospital Cayetano Heredia (CHNH), to characterize Kidney recipients demographically and clinically, and to explore the HLA compatibility with graft survival. Materials and Methods: A retrospective descriptive case series study was conducted in 65 pediatric patients during the period from 2006 to 2020. Results: The mean age was 14.04 (± SD 3.59), 60% (39/65) males and 40% (26/65) females; mixed race 96.92% (63/65), African American 1.54% (1/65), and Caucasian 1.54% (1/65). Previous Kidney replacement therapy modalities included peritoneal dialysis in 61.54% (40/65), hemodialysis in 36.92% (24/65), and medical treatment in 1.54% (1/65). The etiologies were congenital anomalies of the kidney and urinary tract in 49.23% (32/65), glomerulopathies in 33.84% (22/65), and others in 16.93% (11/65). Related living donors 67.69% (44/65), unrelated 1.54% (1/65), and cadaveric 30.77% (20/65). Induction therapy was given to 98.46% (64/65) and triple maintenance therapy to 78.46% (51/65). The most frequent alleles by donor and recipient loci were HLA-A*02 with 43.46% (112/260), HLA-B*35 with 31.15% (81/260) and HLA-DRB1*04 with 28.08% (73/260) and the most frequent haplotype was A*02-B*35-DRB1*04 with 7.69% (10/130). The 10-year graft survival was 91.15% (0-3 mismatch) and 53.33% (4-6 mismatch) (p=0.21). Conclusions: The most frequent HLA alleles and haplotype were A02, B35, DRB104, and A02-B35-DRB104, respectively. No statistical significance was found in the exploration of HLA compatibility on 10-year graft survival.
