BACKGROUND: A common and serious complication of cardiac surgery prompting early
detection and intervention is cardiac surgery-associated acute kidney injury
(CSA-AKI). Urinary chitinase 3-like protein 1 (UCHI3L1) was found to predict AKI
associated with critical illness in adults. Our aims were therefore to evaluate
whether UCHI3L1 can also be used to predict AKI associated with elective cardiac
surgery in adults, and to compare this predictive ability with that of urinary
neutrophil gelatinase-associated lipocalin (UNGAL), more frequently assessed
early serum creatinine (SCr) measurements, and various two-biomarker panels.
METHODS: This was a single-centre prospective cohort study at the eight-bed
cardiac surgery ICU of Ghent University Hospital. AKI was diagnosed and
classified according to the Kidney Disease|Improving Global Outcomes definitions
for the diagnosis and staging of AKI, which are based on SCr and urine output
(UO). Of the 211 enrolled elective cardiac surgery patients, we included 203
patients who had no AKI pre-operatively and at time of post-operative ICU
admission (t1) in the primary endpoint analysis (i.e. AKI stage ?1 within 48 h
after t1), while 210 patients without AKI stage ?2 pre-operatively and at t1 were
included in the secondary endpoint analysis (i.e. AKI stage ?2 within 12 h after
t1). Systemic and/or urine concentrations of Cr, CHI3L1 and NGAL were measured
more frequently than SCr in routine early post-operative ICU practice. UO was
monitored hourly in the ICU. RESULTS: Within 48 h after t1, 46.8% of the patients
had developed AKI (70.5% stage 1, 20.0% stage 2 and 9.5% stage 3). In the early
post-operative period, only SCr was a good predictor of AKI within 48 h after t1
(primary endpoint). SCHI3L1 combined with either UCHI3L1 or UNGAL was a good
predictor of AKI stage ?2 within 12 h after t1 (secondary endpoint). However, SCr
and its absolute difference from pre-operative to early measures after surgery
outperformed these combinations. CONCLUSIONS: We found that more frequent
assessment of the functional biomarker SCr in the early post-operative ICU period
(first 4 h) after elective cardiac surgery in adult patients had good to
excellent predictive value for CSA-AKI, indicating that routine SCr assessment
must become more frequent in order to detect AKI more early. This performance was
in contrast with the inadequate predictive value of the urinary renal stress or
damage biomarkers UCHI3L1 and UNGAL.
