Frequency of development of the acute kidney injury (AKI) in patients underwent different cardiac interventions, and its influence on the cardiorenal prognosis depending on initial function of kidneys is analyzed. 1126 patients (595 men and 531 women) aged from 32 till 68 years (62.3±5.2 years) at which at which prosthetics of valves of heart, coronary artery bypass grafting (CABG) and their combination are examined. In 656 patients (the 1st group) before operation the glomerular filtration rate (GFR) was upper than 60 ml/min/1.73 m2 and in 470 patients (the 2nd group) ranged from 59 to 45 ml/min/1.73 m2, determined by a formula CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration). AKI was diagnosed by level of serum creatinine (sCr) using criteria of AKIN (Acute Kidney Injury Network). In early postoperative period AKI was diagnosed in 23.9% of patients in the 1st group and in 38.7% of patients in the 2nd group ( p

Objective: This study evaluated the relationship between the amount of urinary output during cardiopulmonary bypass and acute kidney injury in the postoperative period of coronary artery bypass grafting.Methods: Two hundred patients with normal preoperative serum creatinine levels, operated on with isolated CABG between 2012-2014 were investigated retrospectively. The RIFLE (Risk, injury, failure, loss of function, and end-stage renal disease) risk scores were calculated for each patient in the third postoperative day. Patients were distributed into two groups in relation to the presence of acute kidney injury or not and these two groups were compared.Results: The urinary output (mL/kg/hour) during cardiopulmonary bypass in the acute kidney injury negative group was significantly higher than in the acute kidney injury positive group (P = .022). In case of a urinary output value 3.70 and lower to predict acute kidney injury positivity, sensitivity was detected as 71.43%. Results of the analysis for urinary output predict positivity of acute kidney injury.Conclusion: We suggest that urine output during cardiopulmonary bypass is a significant criteria that could predict acute kidney injury following coronary artery bypass grafting with cardiopulmonary bypass. Attempts to increase the urine output during cardiopulmonary bypass could help to maintain the renal functions during and after surgery.

Abstract Background The development of acute kidney injury (AKI) is an important indicator of clinical outcomes after cardiac surgery. Elevated preoperative hemoglobin A1c level may be associated with acute kidney injury in patients undergoing coronary artery bypass grafting. This study will investigate the association of preoperative HbA1c levels with AKI after isolated coronary artery bypass grafting (CABG). Results Forty patients undergoing elective CABG were enrolled in this cohort study. Patients are divided into 2 equal groups who underwent isolated coronary artery bypass grafting (CABG): patients with preoperative HbA1c 5.7–6.4% (group A) (prediabetics) and patients with preoperative HbA1c > or = 6.5% (group B) (diabetics). Acute kidney injury according to the Kidney Disease: Improving Global Outcomes criteria developed in 11 patients (27.5%). There was a significant difference between the two groups as regards postoperative urinary NGAL, creatinine level on the 1st day, creatinine level on the 2nd day, urine output on the 1st day, and urine output on the 2nd day (p value was 0.001, 0.002, 0.006, 0.0002, and 0.012 respectively). Postoperative ICU stay duration was statistically significant in the diabetic group (P value 0.009). The need for renal replacement therapy was higher in the diabetic group, but it was not statistically significant between the two groups. Roc analysis shows AUC 0.922 with a significant p value (< 0.0001) and cut of value (≥ 7) with sensitivity 81.82 and specificity 93.10. Conclusion This study revealed that elevated preoperative HbA1c level above 7% showed an increase in incidence of post CABG acute kidney injury along with increase length of postoperative ICU stay.

Abstract Background Cardiac surgery requiring cardiopulmonary bypass is associated with platelet activation. Because platelets are increasingly recognized as important effectors of ischemia and end-organ inflammatory injury, the authors explored whether postoperative nadir platelet counts are associated with acute kidney injury (AKI) and mortality after coronary artery bypass grafting (CABG) surgery. Methods The authors evaluated 4,217 adult patients who underwent CABG surgery. Postoperative nadir platelet counts were defined as the lowest in-hospital values and were used as a continuous predictor of postoperative AKI and mortality. Nadir values in the lowest 10th percentile were also used as a categorical predictor. Multivariable logistic regression and Cox proportional hazard models examined the association between postoperative platelet counts, postoperative AKI, and mortality. Results The median postoperative nadir platelet count was 121 × 109/l. The incidence of postoperative AKI was 54%, including 9.5% (215 patients) and 3.4% (76 patients) who experienced stages II and III AKI, respectively. For every 30 × 109/l decrease in platelet counts, the risk for postoperative AKI increased by 14% (adjusted odds ratio, 1.14; 95% CI, 1.09 to 1.20; P &lt; 0.0001). Patients with platelet counts in the lowest 10th percentile were three times more likely to progress to a higher severity of postoperative AKI (adjusted proportional odds ratio, 3.04; 95% CI, 2.26 to 4.07; P &lt; 0.0001) and had associated increased risk for mortality immediately after surgery (adjusted hazard ratio, 5.46; 95% CI, 3.79 to 7.89; P &lt; 0.0001). Conclusion The authors found a significant association between postoperative nadir platelet counts and AKI and short-term mortality after CABG surgery.

Abstract Background Dickkopf-3 (DKK3) has recently been discovered as a urinary biomarker for the prediction of acute kidney injury (AKI) after cardiac surgery. This finding needs to be confirmed for AKI in other clinical settings. The present study investigates whether DKK3 can predict contrast-induced AKI (CI-AKI). Methods We performed a prospective study in 490 patients undergoing coronary angiography. Primary endpoint was an increase in serum creatinine concentration ≥ 0.3 mg/dl within 72 h after the procedure. DKK3 was assessed < 24 h before coronary angiography. Predictive accuracy was assessed by receiver operating characteristic (ROC) curves. Results CI-AKI was observed in 30 (6.1%) patients, of whom 27 corresponded to stage I and 3 to stage II according to the Acute Kidney Injury Network (AKIN) criteria. Subjects who developed CI-AKI had a 3.8-fold higher urinary DKK3/creatinine ratio than those without CI-AKI (7.5 pg/mg [interquartile range [IQR] 1.2–1392.0] vs. 2.0 pg/mg [IQR 0.9–174.0]; p = 0.047). ROC analysis revealed an area under the curve (AUC) of 0.61. Among subjects without clinically overt chronic kidney disease (estimated glomerular filtration rate [eGFR] > 60 ml/min, urinary albumin creatinine ratio < 30 mg/g), the DKK3/creatinine ratio was 5.4-fold higher in those with subsequent CI-AKI (7.5 pg/mg [IQR 0.9–590.1] vs. 1.38 pg/mg [IQR 0.8–51.0]; p = 0.007; AUC 0.62). Coronary angiography was associated with a 43 times increase in the urinary DKK3/creatinine ratio. Conclusions Urinary DKK3 is an independent predictor of CI-AKI even in the absence of overt chronic kidney disease (CKD). The study thereby expands the findings on DKK3 in the prediction of postoperative loss of kidney function to other entities of AKI. Graphic abstract
