Background

Accurate pre-transplant prediction of late graft function remains an unmet need in kidney transplantation. The aim of this study was to evaluate HLA genes expression levels in pre-implantation biopsies (PIB) of deceased donor kidneys as markers for long-term graft outcome.

Methods

HLA genes expression analysis was initially performed using microarray data of 53 PIB, previously generated by our laboratory. The validation analysis was performed by real-time PCR in 116 PIB from an independent cohort.

Results

The microarray data showed association between high expression levels of HLA class II genes, especially HLA-DQB1 and -DQB2, in kidneys from young (18 to 49-year-old) donors and poor (eGFR < 45 mL/min/1.73 m2) 1- and 5-year graft function. A subsequent study in an independent cohort, in which only HLA-DQB2 expression was evaluated, validated the association between increased HLA-DQB2 expression in PIB of kidneys from young donors and poor 1-year graft function: expression levels ≥0.0025 relative units conferred an odds ratio of 22.5, with positive and negative predictive values of 71.4% and 90.0%, respectively.

Conclusion

Heightened expression of HLA-DQB1 and -DQB2 in PIB are promising tools for pre-transplant risk assessment of poor late graft function in transplants with kidneys from 18 to 49-year-old donors."xsd:string
