Abstract Background Cardiac-surgery associated acute kidney injury (CSA-AKI) remains an important and frequent complication in patients undergoing cardiac surgery and is associated with a poor short- and long-term prognosis. The incidence for CSA-AKI according to Acute Kidney Injury Network criteria (AKIN) varies between 3% and 50%. CSA-AKI requiring temporary renal replacement therapy (RRT) occurs in 5% to 20% of these patients and is associated with a high mortality rate. Objective To detect the relation between prolonged cardiopulmonary bypass time in cardiac surgery and the incidence of post-operative acute kidney injury. Patients and Methods This is an observational retrospective study conducted on (80) adult patients who underwent elective cardiac surgery at Aswan Heart Centre (Magdi Yacoub Foundation) after the approval of the Ethical Medical Committee of Aswan Heart Centre. Results Results of the statistical analysis of the present study showed that mean CPB duration was prolonged in the AKI group of patients (155 min) than the non-AKI group of patients (129 min). Conclusion Prolonged cardiopulmonary bypass duration may be an independent risk factor for acute kidney injury post cardiac surgery in adult patients.

Background: Acute kidney injury is a common problem with various causes and consequences like electrolyte disturbances in the form of hypocalcaemia, hypokalemia, hyperkalemia depending on the phase. Hypomagnesaemia is one of the most common electrolyte disturbance found in hospitalized patients especially in the critically ill patients. Prevalence of hypomagnesemia varies from 11 to 65% in different studies. Hence, we decided to conduct a study to evaluate correlation of serum magnesium levels in AKI.Methods: A cross-sectional, hospital based time bound study was conducted between November 2016 and August 2018 with a sample of 100 patients aged 18-65 years and who had AKI were included and patients with diabetes mellitus, multi-organ dysfunction, obstructive uropathy and drug induced AKI were excluded from study. The decrease in magnesium <1.7 mg/L was defined as hypomagnesaemia. AKI was defined as per AKIN criteria. Day 1, day 3 and day 6 magnesium levels were measured.Results: Prevalence of hypomagnesaemia was 53%, 30% and 36% on day 1, day 3 and day 6 respectively. It was observed that there was a positive correlation between serum magnesium, and serum creatinine. Normomagnsemia and hypermagnesemia on day 1, 3 and 6 were significantly associated with recovery of AKI (p<0.001).Conclusions: The prevalence of hypomagnesemia was significantly higher in AKI patients and normal magnesium and hypermagnesium on day 1, 3 and day 6 was associated with recovery than non-recovery. Hypomagnesemia was associated more with non-recovery then recovery.

The Impact

Background and objective. Acute kidney injury (AKI) following cardiac surgery with cardiopulmonary bypass (CPB) is polyethiological clinical syndrome. During CPB haemodilution develops, which is useful in reducing the risk of thrombosis; however, haemodilutional anaemia decreases oxygen transfer and provokes tissue hypoxia, which can lead to acute organ damage. The aim of the study was to find out the impact of perioperative anaemia on AKI after cardiac surgery with CPB. Materials and methods. This prospective study included 58 adult patients undergoing elective cardiac surgery with CPB, without any preoperative chronic renal disease or any systemic autoimmune disease. Serum concentrations of NGAL had been tested before the surgery, 2 hours, 6 hours, and one day after the surgery. Perioperative anaemia was assessed according to the Ht value before the surgery, the Ht value during CPB, and immediately after the surgery. Results. The rate of haemodilutional anaemia is 77.59% in this study. The average of serum NGAL concentration before CPB was 63.95 ± 33.25 ng/mL and it was significantly lower than the average concentration 2 hours after the surgery, 6 hours after the surgery and one day after the surgery (respectively 148.51 ± 62.39, 119.44 ± 55, 128.70 ± 59.04 ng/mL, p < 0.05). AKI developed in 46.55% of the patients. A significant positive reasonable correlation between the development of perioperative anaemia and AKI was determined (r = 0.50, p < 0.05). Conclusions. Post-operative AKI after cardiac surgery with CPB has a moderate positive correlation with perioperative haemodilutional anaemia. A longer CPB time and aortic cross-clamping time were found to be the risk factors for the development of AKI.

Background: Acute kidney injury (AKI) is a common and serious complication faced by children following ventricular septal defect (VSD) surgery with cardiopulmonary bypass (CPB). The objective of this study was to explore potential predictors inherent to AKI.Methods: VSD infants who were scheduled for elective cardiac surgery with CPB from 2017 to 2020 were enrolled in this study. Based on the Pediatric Risk, Injury, Failure, Loss, End-Stage Renal Disease (pRIFLE) criteria, patients were divided into AKI and non-AKI groups. Univariate and multivariate logistic regression analyses were carried out in order to evaluate potential risk factors for AKI. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive probabilities of risk factors for AKI.Results: Of all the 338 enrolled VSD infants, 49 manifested AKI with an incidence of 14.5% (49/338). The ROC curve indicated that albumin-to-fibrinogen ratio (AFR) during CPB was a significant predictor of AKI [area under the curve (AUC), 0.711; p &lt; 0.001]. Based on the univariate and multivariate logistic analyses, AFR during CPB [odds ratio (OR), 1.89; 95% confidence interval (CI), 1.22–2.76, p = 0.011] was the only independent risk factor for AKI.Conclusions: This study demonstrated that a low AFR (&lt;9.35) during CPB was an independent risk factor for AKI in VSD infants following cardiac surgery with CPB.

Introduction: Acute kidney injury (AKI) is a serious complication of cardiac surgery with cardiopulmonary bypass (CPB). Postoperative AKI develops in 30% to 52% of cardiac surgery patients and 2% to 5% of these patients require renal replacement therapy. Hypothesis: We hypothesized that nitric oxide treatment during cardiac surgery with CPB can decrease AKI incidence in adult patients. The aim of study was to evaluate the effects of nitric oxide supplementation to CPB circuit on the development of cardiac surgery-associated AKI. Methods: A prospective randomized controlled study included 96 patients with moderate risk of renal complications who underwent elective cardiac surgery with CPB. The study protocol was registered at www.clinicaltrials.gov (#NCT03527381). Patients were randomly assigned to either the nitric oxide supplementation to CPB circuit (NO-treatment group, n = 48) or the usual care (control group, n = 48). 40-ppm nitric oxide was administered in NO-treatment group during the entire CPB period. The primary outcome was AKI incidence. Results: Nitric oxide treatment was associated with a significant decrease in AKI incidence (10 (20.8%) versus 20 (41.6%); RR 0.5 (95% CI 0.26-0.95; p =0.023) and a higher urine output during CPB (2.6 [2.1;5.08] versus 1.7 [0.80;2.50] mL/kg/h; p = 0.0002). Urinary neutrophil gelatinase-associated lipocalin levels were significantly lower in NO-treatment group 4 h after surgery: 1.12 [0.75;5.8] versus 4.62 [2.02;34.55] ng/mL; p = 0.005. Concentrations of nitric oxide metabolites in NO-treatment group significantly increased at 5 min post-clamping, 5 min after declamping, and at the end of surgery. The concentrations of proinflammatory and anti-inflammatory mediators and free plasma hemoglobin did not significantly differ between groups. Conclusions: Nitric oxide administration to patients at moderate risk of renal complications undergoing elective cardiac surgery with CPB was associated with a decrease in AKI incidence. The implications of study for clinical practice expand the array of methods, which may be used for prevention of AKI in cardiac surgery patients.

Background. Cardiac surgery-associated acute kidney injury (CSA-AKI) depicts a major complication after cardiac surgery using cardiopulmonary bypass (CPB).Objective. CSA-AKI has clearly been linked to increased perioperative morbidity and mortality. Dysregulations of vasomotor tone are assumed to be causal for CSA-AKI. While catechol-O-methyltransferase (COMT) is involved in metabolizing catecholamines, a single-nucleotide polymorphism (SNP) in the COMT gene leads to different enzyme activities according to genotype. Pilot studies found associations between those COMT genotypes and CSA-AKI.Methods. We prospectively included 1741 patients undergoing elective cardiac surgery using cardiopulmonary bypass (CPB). Patients were genotyped for COMT-Val158Met-(G/A) polymorphism (rs4680).Results. Demographic characteristics and procedural data revealed no significant differences between genotypes. No association between COMT genotypes and the RIFLE criteria could be detected. A multiple linear regression analysis for postoperative creatinine increase revealed highly significant associations for aortic cross-clamp time (P<0.001), CPB time (P<0.001), norepinephrine (P<0.001), and age (P<0.001). No associations were found for COMT genotypes or baseline creatinine. With anR2=0.39and a sample size of 1741, the observed power of the regression analysis was >99%.Conclusions. Based on our results, we can rule out an association between the COMT-Val158Met-(G/A) polymorphism and the appearance of CSA-AKI.

Summary Background Cardiac surgery-associated acute kidney injury (CSA-AKI) frequently occurs in patients assessed as low-risk for developing CSA-AKI. Neutrophil Gelatinase-Associated Lipocalin (NGAL), Kidney Injury Molecule-1 (KIM-1) and lactate are promising biomarkers of CSA-AKI but have not yet been explored in low-risk patients. Aim To evaluate urinary NGAL (uNGAL), KIM-1 and lactate as biomarkers of CSA-AKI in patients with low-risk for developing CSA-AKI. Methods This prospective, observational study included 100 adult elective cardiac surgery patients assessed as low-risk for developing CSA-AKI. UNGAL, KIM-1 and lactate were measured preoperatively, at the end of cardiopulmonary bypass (CPB) and 3, 12, 24 and 48 h later. Results Fifteen patients developed CSA-AKI. Patients with CSA-AKI had significantly higher lactate but similar uNGAL and KIM-1 levels compared to patients without CSA-AKI. Unlike uNGAL and KIM-1, postoperative lactate was good biomarker of CSA-AKI with the highest odds ratio (OR) 2.7 [1.4–4.9] 24 h after CPB. Peak lactate concentration ≥ 4 mmol/L carried dramatically higher risk for developing CSA-AKI (OR 6.3 [1.9–20.5]). Conclusions Unlike uNGAL and KIM-1, postoperative lactate was significant independent predictor of CSA-AKI with the highest odds ratio 24 h after CPB.
