Acute kidney injury (AKI) develops in up to 40% of patients after cardiac
surgery. The soluble urokinase plasminogen activator receptor (suPAR) has been
identified as a biomarker for incident chronic kidney disease (CKD).
Proenkephalin (proENK) also has been shown to be a biomarker for renal
dysfunction. We hypothesized that pre-surgery suPAR and proENK levels might
predict AKI in patients undergoing cardiac surgery. Consecutive patients (n =
107) undergoing elective cardiac surgery were studied prospectively. Clinical
data, laboratory parameters, suPAR and proENK serum levels were assessed before
operation, after operation and days one and four post-operatively. A total of 21
(19.6%) patients developed AKI within the first four days after elective surgery.
Serum levels of suPAR and proENK, but not of creatinine, were significantly
higher before surgery in these patients compared to those patients without AKI.
This difference remained significant for suPAR, if patients with or without AKI
were matched for risk factors (hypertension, diabetes, CKD). If cardiac surgery
patients with pre-existing CKD (n = 10) were excluded, only pre-operative suPAR
but not proENK serum levels remained significantly elevated in patients with
subsequent AKI. Thus, our findings indicate that suPAR may be a predictive
biomarker for AKI in the context of cardiac surgery, even in patients without
underlying CKD.
