A lot of efforts have been done to identify the risk factors that tend to diminish the incidence of delayed graft function (DGF). Recently, the secretory leukocyte peptidase inhibitor (SLPI) was proposed as a biomarker candidate for acute kidney injury (AKI), since high level of it was found in plasma and urine of patients. The aim of the present work was to determine if the level of SLPI in the cold preservation solution could be a useful marker to predict early and late kidney function after transplantation.
Twenty three patients were enrolled. Kidneys were perfused with 1 liter of Wisconsin solution before the transplantation. The SLPI concentration was measured on two fractions of the perfused solution, i.e. the first 50 ml (SLPI-A) and the last 50 ml (SLPI-B). Direct correlations were found between SLPI-B and DGF risk factors (donor age, p=0.013; pre-ablation plasma creatinine values, p=0.047; cold ischemia time, p=0.01). Furthermore, the patients with DGF had statistically significant higher SLPI-B values compared with patients without DGF (Figure 1).
Also, we found an indirect correlation between SLPI-B and MDRD measured at patient discharge. Interestingly, patients (6) that suffered rejections during the first 6 months after transplantation, had higher values of SLPI-A and SLPI-B than patients without rejections.
Remarkably, we find a direct association between KDPI (a score that evaluate the quality of deceased-donor kidneys) and SLPI-B (r=0.55; p<0.005) (Figure 2B).
These results suggest that SLPI concentration in the perfusion liquid could be a good predictor marker for short and long term clinical outcomes in kidney transplantation.
