Background Cardiac surgery-associated acute kidney injury (CSA-AKI) is an important and serious complication that affects morbidity and mortality. We studied both pediatric and adults using the definition of the Acute Kidney Injury Network (AKIN). Methods This is an observational retrospective cohort study done at King Abdulaziz University Hospital in Jeddah, Saudi Arabia approved by ethical committee. The exclusion criteria were baseline serum creatinine (SCr) ≥ 4 mg/dL or preexisting renal failure requiring dialysis, reoperation, death within 24 hours postoperatively, and operative mortality or missing data. 941 patients were included in the analysis using the statistical software  SPSS, version 15.0. Results 28.68% in the adult group and 20.07% in the pediatric group developed CSA-AKI. Adult risk factors included age group of 60-69 years, cardiopulmonary bypass (CPB), number of grafts and hypertension. In the pediatric group, CPB, aortic cross-clamping (ACX) and the lower preoperative SCr are the main risk factors Conclusion Conventional conservative management and preoperative Identification of predictor risk factors are essential for prevention of CSA-AKI which constitute the main strategy for optimal management.

Objective: To evaluate the perioperative risk factors associated with postoperative AKI in patients undergoing cardiac surgery. Methodology: Between January 2011 and December 2017, we analyzed prospectively 544 patients, who were divided into two groups: patients with acute kidney injury associated with cardiac surgery (AKI-ACS) defined as an increase of 0.3 mg/dL or 1.5 times the baseline serum creatinine value and control group formed by patients without AKI-ACS. We compared patients and surgical variables using the chi-square test, Fisher's exact test, and mann-Whitney test and logistic regression. Results: AKI-ACS occurred in 29.8% of the patients. In the univariate analysis, the following variables presented a statistically significant difference: male gender (p=0.0087), age (p<0.0001), body mass (p=0.035), BMI (p=0.001), thoracic aortic surgery (p=0.029), use of extracorporeal circulation (p=0.012), CPB time (p=0.0001), aortic clamping time (p=0.0029), use of vasoactive drugs in post-operative  period (p=0.017), preoperative kidney function (p<0.0001), presence of diabetes mellitus (p=0.008) and NYHA functional class (p=0.041). In the multivariate analysis, the following variables presented a statistical difference: male gender (OR 2.11), higher BMI (OR 2.11), worse preoperative renal function, demonstrated by creatinine clearance (OR 0.13), longer cardiopulmonary bypass (OR 1.008). Conclusion: The independent predictors for LRA-ACC were male gender, higher body mass index, worse preoperative renal function, and more complex surgeries associated with longer cardiopulmonary bypass.

Acute Kidney Injury Development

Introduction. Acute kidney injury associated with cardiac surgery is a common and significant postoperative complication. With a frequency of 9 - 39% according to different studies, it is the second most common cause of acute kidney injury in intensive care units, and an independent predictor of mortality. This study aimed to investigate the importance of preoperative hemoglobin and uric acid levels as risk factors for acute kidney injury in the postoperative period in cardiac surgery patients. Material and Methods. The study included a total of 118 patients who were divided into two groups. Each group included 59 patients; the fist group included patients who developed acute kidney injury and required renal replacement therapy, and the second included patients without acute kidney injury. Types of cardiac surgery included coronary, valvular, combined, aortic dissection, and others. All necessary data were collected from patient medical records and the electronic database. Results. A statistically significant difference was found between the groups in preoperative hemoglobin levels (108.0 vs. 143.0 g/l, p = 0.0005); postoperative urea (26.4 vs. 5.8 mmol/l, p = 0.0005) and creatinine (371.0 vs. 95.0 ?mol/l, p = 0.0005), acute phase inflammatory reactants C-reactive protein (119.4 vs. 78.9 mg/l, p = 0.002) and procalcitonin (7.0 vs. 0.2 ng/ml, p = 0.0005), creatine kinase myocardial band isoenzyme (1045.0 vs. 647.0 mg/l, p = 0.014); duration of extracorporeal circulation (103.5 vs. 76.0 min, p = 0.0005) and ascending aortic clamp during cardiac surgery (89.0 vs. 67.0 min, p = 0.0005). The exception was the preoperative uric acid level, where there was no statistically significant difference (382.0 vs. 364.0 ?mol/l, p = 0.068). There was a statistically significant correlation between the use of inotropic agents and acute kidney injury development. Conclusion. There is a correlation between the preoperative low hemoglobin levels and postoperative acute kidney injury. There is no statistically significant correlation between the preoperative levels of uric acid and postoperative acute kidney injury.

Objective. Neutrophil gelatinase-associated lipocalin (NGAL) measured by a research ELISA is described as an early marker of acute kidney injury (AKI). The aim of this study is to define the usefulness of plasma NGAL (pNGAL) and urine NGAL (uNGAL) measured with platform analysers to detect AKI 3 hours after cardiac surgery in fifty adult patients. Methods and Main Results. pNGAL and uNGAL were measured before and 3 hours after cardiac surgery. AKI, defined following the acute kidney injury network definition, was observed in 17 patients. pNGAL was >149 ng/mL in 8 patients with AKI, two of them died in the follow-up. We also observed elevated pNGAL in 8 patients without AKI. Only one uNGAL was >132 ng/mL among the 15 AKI patients. Sensitivity of pNGAL for prediction of AKI is 47% and specificity is 75.7%. The positive likelihood ratio (LR+) is 1.9 and negative likelihood ratio (LR−) is 0.7. uNGAL performance is slightly improved when reported to urinary creatinine. Following this study, a ratio >62 ng/mg assure a sensitivity of 66.6% and a specificity of 78.5%. LR+ is 3 and a LR− is, 0.42. Conclusions. Three hours after cardiac surgery, pNGAL predicts AKI with a low sensitivity and specificity.

Acute renal failure definitions have changed dramatically over the last 5 to 10 years as a result of criteria established through the following consensus statements/organizations: RIFLE (Risk, Injury, Failure, Loss of function, End stage renal disease), AKIN (Acute Kidney Injury Network), and KDIGO (Kidney Disease: Improving Global Outcomes). In 2002, the Acute Dialysis Quality Initiative was tasked with the goal of establishing a consensus statement for acute kidney injury (AKI). The first order of business was to provide a standard definition of AKI. Up to this point, literature comparison was challenging as studies lacked uniformity in renal injury definitions. Implementing results into evidence-based clinical practice was difficult. The panel coined the term “acute kidney injury,” encompassing previous terms, such as renal failure and acute tubular necrosis. This new terminology represented a broad range of renal insults, from dehydration to those requiring renal replacement therapy (RRT). This review provides an algorithmic approach to the epidemiology, pathophysiology, diagnosis, prevention, and management of AKI. Also discussed are special circumstances, including rhabdomyolysis, contrast-induced nephropathy, and hepatorenal syndrome. Tables outline the AKIN criteria, most current KDIGO consensus guidelines for definition of AKI, differential diagnosis of AKI, agents capable of causing AKI, treatment for specific complications associated with AKI, and options for continuous RRT. Figures show the RIFLE classification scheme and KDIGO staging with prevention strategies. This review contains 1 management algorithm, 2 figures, 6 tables, and 85 references.

Abstract Background The clinical correlates, prognosis and determinants of acute kidney injury (AKI) in patients with coronavirus disease 2019 (Covid-19) remain largely unclear. Methods We retrospectively reviewed medical records of all adult patients with laboratory-confirmed Covid-19 who were admitted to the intensive care unit (ICU) between January 23rd 2020 and April 6th 2020 at Wuhan JinYinTan Hospital and The First Affiliated Hospital of Guangzhou Medical University. Results Among 210 patients, 131 were males (62.4%). The median Age was 64 years (IQR: 56–71). Of 92 (43.8%) patients who developed AKI during hospitalization, 13 (14.1%), 15 (16.3%) and 64 (69.6%) were classified as being at stage 1, 2 and 3, respectively. 54 patients (58.7%) received continuous renal replacement therapy. Age, sepsis, nephrotoxic drug, invasive mechanical ventilation and elevated baseline serum creatinine levels were associated with the occurrence of AKI. Renal recovery during hospitalization was identified among 16 patients with AKI (17.4%), who had a significantly shorter time from admission to AKI diagnosis, lower incidence of right heart failure and higher ratio of partial pressure of oxygen to the fraction of inspired oxygen. Of 210 patients, 93 deceased within 28 days of ICU admission. AKI stage 3, critical disease, greater Age and the lowest ratio of partial pressure of oxygen to the fraction of inspired oxygen being < 150 mmHg were independently associated with death. Conclusions Among patients with Covid-19, the incidence of AKI was high. Our findings of the risk factors of the development of AKI and factors associated with renal function recovery may inform clinical management of patients with critical illness of Covid-19.
