Abstract:
Objective To explore the value of neutrophils gelatinases related lipid a carrier protein (NGAL),renal injury molecule-1 (KIM-1) and serum creatinine (SCr) for early diagnosis in adult cardiac surgery after acute renal injury (AKI).Methods Blood and urine samples of 65 cardiac surgery patients before and 24,48,72 h after surgery were collected,SCr,urine NGAL and KIM-1 levels was detected,among whom AKI occurred in 34 cases(AKI group),did not occur in 31 cases (non AKI group),and they were compared with 20 cases of healthy physical examination (control group).Logistic regression model was used to judge the value of early diagnosis of SCr,urine NGAL and KIM-1.Results The incidence of AKI after cardiac surgery was 52.31％ (34/65).The SCr,urine NGAL and KIM-1 levels in AKI group and non AKI group before and 24,48,72 h after surgery were significantly higher than those in control group [SCr:(62.44 ±22.26),(77.38 ±24.38),(98.24 ±25.02),(98.14 ±45.26)μmol/L and (56.67 ±21.68),(59.25 ± 15.58),(55.40 ±22.91),(40.10 ±23.45)μmol/L vs.(16.43 ±5.01)μmol/L;urine NGAL:(4.81 ±0.65),(9.48 ±3.29),(11.87 ±3.93),(7.66 ± 1.52) μg/L and (4.67 ±0.53),(8.89 ± 2.64),(11.46 ± 3.60),(7.47 ± 1.63)μg/L vs.(2.87 ± 0.48) μg/L; KIM-1:(47.93 ± 5.54),(61.89 ± 12.44),(100.21 ± 27.32),(67.69 ± 8.72) μ g/L and (47.12 ± 4.08),(56.38 ± 9.27),(90.14 ± 27.26),(69.40 ±8.90) μ g/L vs.(32.21 ± 12.54)μ g/L] (P ＜ 0.01).Urine NGAL and KIM-1 levels in AKI group and non AKI group 24,48,72 h after surgery were significantly higher than those before surgery (P＜ 0.01).SCr,urine NGAL and KIM-1 levels in AKI group 24 h after surgery were significantly higher than those in non AKI group (P＜ 0.01).Twenty-four hours after surgery,the sensitivity and specificity of urine NGAL,KIM-1 in the diagnosis of AKI,compared with that of SCr had no statistical significance (P ＞ 0.05).Conclusions The adults who accept extracorporeal circulation cardiac surgery appear high incidence of AKI.Twenty-four hours after surgery,early biological markers-urine AKI,KIM-1,has similar sensitivity and specificity with traditional diagnostic gold standard of SCr.
