    Histocompatibility significantly impacts early kidney transplant outcomes. Better HLA matching and lower initial serum creatinine levels correlate with improved one-year graft survival rates, highlighting the importance of donor selection and early post-transplant monitoring.

    Area of Science:

    • Nephrology
    • Immunology
    • Transplantation Science

    Background:

    • Histocompatibility matching plays a crucial role in organ transplantation success.
    • Early post-transplant monitoring of kidney function is essential for predicting long-term outcomes.

    Purpose of the Study:

    • To investigate the relationship between human leukocyte antigen (HLA) matching, early serum creatinine levels, and one-year graft survival in kidney transplant recipients.
    • To explore the correlation between cyclosporine dosage, rejection episodes, and graft survival.

    Main Methods:

    • Retrospective analysis of kidney transplant recipients.
    • Measurement of average serum creatinine levels within the first 20 days post-transplantation.
    • Correlation analysis between HLA matching, serum creatinine, cyclosporine dosage, rejection rates, and one-year graft survival.

    Main Results:

    • Lower average serum creatinine levels were observed in transplants from HLA-identical siblings compared to parental donors.
    • Better HLA-A,B and HLA-A,B,DR matching correlated with lower serum creatinine levels.
    • Serum creatinine levels in the first 20 days post-transplant were predictive of one-year graft survival, with levels <2.4 mg/dl associated with >80% survival and levels >7.5 mg/dl associated with ~30% lower survival.
    • Cyclosporine dosage varied significantly between centers and did not directly correlate with graft survival or creatinine levels in this preliminary analysis.
    • Patients experiencing later rejection (11-60 days) received lower cyclosporine dosages than those with early rejection or no rejection.

    Conclusions:

    • Early post-transplant serum creatinine levels are a significant indicator of kidney transplant success.
    • Optimal HLA matching, particularly at the HLA-A,B,DR loci, may contribute to better early graft function.
    • Further research with larger cohorts is needed to confirm findings and elucidate the role of immunosuppression protocols.
