| Popis: | ABSTRACTIntroduction:The success of kidney transplantation depends on prevention of organ rejection by the recipient’s immune system, which recognizes alloantigens present in transplanted tissue. Human leukocyte antigen (HLA) typing is one of the tests used in pre-renal transplantation and represents one of the most important factors for a successful procedure.Objective:The present study evaluated creatinine and cytokines plasma levels in kidney transplant patients according to pre-transplant HLA typing.Methods:We assessed 40 renal transplanted patients selected in two transplant centers in Belo Horizonte (MG).Results:Patients were distributed into three groups according to HLA compatibility and, through statistical analysis, the group with more than three matches (H3) was found to have significantly lower post-transplant creatinine levels, compared to groups with three or fewer matches (H2 and H1, respectively). The median plasma levels of cytokines interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α), and interleukin 10 (IL-10) were evaluated according to the number of matches. Pro-inflammatory cytokines (IL-6 and TNF-α) were significantly higher in groups with lower HLA compatibility. On the other hand, the regulatory cytokine IL-10 had significantly higher plasma levels in the group with greater compatibility between donor and recipient.Conclusion:These findings allow us to infer that pre-transplant HLA typing of donors and recipients can influence post-transplant renal graft function and may contribute to the development and choice of new treatment strategies. |
