Abstract
BACKGROUND
Fractalkine is a member of the chemokine family that acts as an adhesion molecule and as an extracellular chemoattractant promoting cellular migration. In this study, we analysed the association between the CX3CR1 gene V249I (rs3732379) SNP and renal allograft function.
METHODS
The study enrolled 270 Caucasian kidney allograft recipients. The following parameters were recorded in each case: the recipient's age and gender, delayed graft function (DGF) defined as the need for dialysis in the first 7 days after transplantation, occurrence and number of episodes of acute rejection (AR), and chronic allograft dysfunction (CAD).
RESULTS
Delayed graft function was diagnosed in 39.2% of individuals with the CC genotype, 22.7% with CT and 23.5% of those with the TT genotype. The differences were statistically significant (CC vs. TT+CT: OR = 2.17; 95% CI = 1.28-3.70, p = 0.0042). In multivariate analysis the CC genotype was an independent and significant predictor of higher risk of DGF. The distribution of genotypes and alleles of the CX3CR1 gene polymorphism among patients with and without AR as well as CAD did not differ significantly.
CONCLUSIONS
The results of this study suggest that the CX3CR1 gene V249I (rs3732379) SNP CC genotype is associated with increased risk of DGF.
