ABSTRACT
<p><b>OBJECTIVE</b>To explore the impact of killer cell immunoglobulin-like receptor (KIR) gene mismatch on the outcomes of renal transplantation.</p><p><b>METHODS</b>We collected the data from 111 donor-recipient pairs of kidney transplant and analyzed the status of KIR gene matching, acute rejection (AR), and 1-year and 3-year survival of the recipients who were followed continuously for over 37 months.</p><p><b>RESULTS</b>Seventeen KIR genes were expressed in both recipient and donor groups, and the frequency of KIR3DS1 was significantly higher in the recipients than in the donors (38.75% vs 24.66%, OR=2.17, χ² = 3.94, P<0.05). The average rate of donor-recipient KIR matching was 82.53%. The donor-recipient KIR2DS1 matching rate was significantly higher in AR group than in no-AR group (85.00% vs 54.95%, χ² = 6.19, P<0.05). The rate of donor-recipient KIR AB-AB genotype was significantly higher in AR group than in no-AR group (33.33% vs 8.00%, P<0.05). The 1- and 3-year survival rates was 94.59% and 82.88% in these recipients, respectively. The frequency of donor KIR-AB genotpye was significantly higher in recipients with poor outcomes (57.89% vs 29.63%, χ² = 8.19, P<0.05); the frequency of both donor and recipient KIR-AB genotype was also significantly higher in recipients with poor prognoses (36.84% vs 9.78%, χ² = 14.87, P<0.05).</p><p><b>CONCLUSIONS</b>KIR3DS1 may be the susceptible gene associated with uremia. A KIR-AB genotype of either the donor or the recipient can increase the risk of AR and reduce the 1- and 3-year survival rate. This finding can be of ethically importance in choosing a living related donor.</p>
