Renal Ischemia Reperfusion Injury

Renal ischemia/reperfusion (IR) injury is one of the most important risk factors for the occurrence of delayed graft function (DGF) after kidney transplantation; however, its mechanism remains not fully understood. In the present study, we screened differentially expressed genes in a murine model of renal IR injury by using high-throughput assays. We identified Corin as one of the most significantly downregulated genes among 2218 differentially expressed genes (≥2-fold, P<0.05). By using a real-time qPCR assay, we observed that the expression of renal Corin in IR-injured mice was reduced to 11.5% of the sham-operated mice and that the protein level of renal Corin in IR-injured mice was also downregulated. Interestingly, renal IR injury in mice induced the downregulation of Corin in heart tissues, suggesting that the overall synthesis of Corin may be suppressed. We recruited 11 recipients complicated with DGF and 16 without DGF, and plasma Corin concentrations were determined by ELISA. We observed that the plasma Corin levels were indeed reduced in recipients complicated with DGF (0.98 vs. 1.95 ng/ml, P<0.05). These findings demonstrate that Corin may be a potential biomarker of DGF after kidney transplantation and may participate in the regulation of renal IR injury.

Background Delayed graft function (DGF) is a common complication following kidney transplantation and is associated with ischemia-reperfusion injury (IRI). Lymphocytes contribute to the pathogenesis of IRI and ischemia-reperfusion related delayed graft function Materials and Methods 135 Caucasian patients received a kidney graft from deceased heart-beating organ donors. We divided patients into 2 groups- patients with the eGFR>=30 on the 21st day post-transplantation (n=36) and patients with the eGFR<30 on the 21st day post-transplantation (n=99) to assess kidney graft function. We measured the serum creatinine levels on 1st and 2nd post-transplant day and preoperative levels of monocytes, lymphocytes, platelets and neutrophils and their ratios. Results We have found statistically significant differences between the eGFR<30 and the eGFR>=30 groups in the average lnLymphocytes (0,36 +/-0,6 vs -0,016 +/-0,74 respectively p=0,004) lnNLR ( 1,27 +/-0,92 vs. 1,73+/-1,08 p=0,016) lnLMR (1,01 +/-0,57 vs. 0,73 +/-0,64 p=0,02), lnPLR (4,97 +/-0,55 vs. 5,26 +/- 0,67 p=0,023) and CCR2% (-20,20 +/- 21,55 vs. -4,29 +/- 29,62 p=0,004 . On univariate analysis, factors of lnLymphocytes >=0,22 (OR=0,331 95%CI 0,151-0,728 p=0,006), lnLMR>=1,4 (OR=0,255 95%CI 0,072-0,903 p=0,034) were associated with worse graft function while lnNLR>=1,05 (OR=2,653 95%CI 1,158-6,078 p=0,021), lnPLR>=5,15 (OR=2,536 95%CI 1,155-5,566 p=0,02) and CRR2 (OR=3,286 95% CI 1,359-7,944 p=0,008) indicated better graft function Conclusion Higher absolute lymphocyte count (lnLymphocytes) and lnLMR as well as lower lnNLR and lnPLR were associated with lower eGFR on the 21st day after kidney transplantation. On multivariate analysis CRR2 in combination with either lnLymphocytes, lnNLR or lnPLR improved the accuracy of detecting patients with poor graft function.
