Contrast-induced acute kidney injury, previously known as contrast-induced nephropathy, is an important complication in the catheterization laboratory. The definition of contrast-induced acute kidney injury should be harmonized with the Kidney Disease International Global Outcomes criteria which calls for >=0.3 mg/dl (26.5 micromol/L) rise in serum creatinine within 48 hours of contrast exposure. If there is a sustained reduction in estimated glomerular function from a baseline above 60 to a new baseline below 60 ml/min/1.73 m2 at 90 days after the procedure, then a definition of chronic kidney disease (Stage 3) would be met as a late outcome of this complication.

Contrast-induced acute kidney injury (AKI), previously known as contrast-induced nephropathy (CIN) is an important complication in the catheterization laboratory. The most commonly used definition in clinical trials was a rise in serum creatinine (Cr) of 44.2mmol/L (0.5mg/dL) or a 25% increase from the baseline value, assessed at 48h after the procedure. In 2007, the Acute Kidney Injury Network proposed the definition to a rise in serum Cr ≥26.5mmol/L (0.3mg/dL) or a 50% rise in Cr with oliguria which is compatible with previous definitions and is a new standard to follow. If there is a sustained reduction in estimated glomerular function (eGFR) from a baseline above 60 to a new baseline below 60mL/min/1.73m2 at 90 days after the procedure, then a definition of chronic kidney disease (CKD) (Stage 3) would be met as a late outcome of this complication.

Acute Kidney Injury Stage

Background: Acute kidney injury (AKI) is common among cardiac arrest survivors. However, the outcomes and predictors are not well studied. Methods: This is a cohort study of cardiac arrest patients enrolled from January 2012 to December 2016 who were able to survive for 24 hours post-cardiopulmonary resuscitation. Patients with anuria, chronic kidney disease (stage 5), and end-stage renal disease were excluded. Acute kidney injury (stage 1) or higher was defined using Kidney Disease: Improving Global Outcomes classification. Multivariable adjusted regression models were used to compute hazard ratio (HR) for association of AKI with risk of mortality and odds ratio (OR) with risk of poor neurological outcomes after adjusting for demographics, comorbidities, and medical therapy. Multivariable logistic regression model was used to compute OR for association of various predictors with AKI. Results: Of 842 cardiac arrest survivors, 588 (69.8%) developed AKI. Among AKI patients, 69.4% died compared with 52.0% among non-AKI patients. In multivariable adjusted Cox proportional hazard model, development of AKI post-cardiac arrest was significantly associated with mortality (HR: 1.35; 95% confidence interval [CI]: 1.07-1.71, P = .01) and poor neurological outcomes defined as cerebral performance category >2 (OR: 2.27; 95% CI: 1.45-3.57, P < .001) and modified Rankin scale >3 (OR: 2.22; 95% CI: 1.43-3.45, P < .001). Postdischarge dialysis was also associated with increased risk of mortality (HR: 2.57; 95% CI: 1.57-4.23, P < .001). Use of vasopressors was strongly associated with development of AKI and continued need for postdischarge dialysis. Conclusions: Acute kidney injury was associated with increased risk of mortality and poor neurological outcomes. There is need for further studies to prevent AKI in cardiac arrest survivors.

Background: Postoperative Acute Kidney Injury (AKI) is a common and serious complication associated with significant morbidity and mortality. While several pre- and intra-operative risk factors for AKI have been recognized in cardiac surgery patients, relatively few data are available regarding the incidence and risk factors for perioperative AKI in other surgical operations. The aim of the present study was to determine the risk factors for perioperative AKI in patients undergoing major abdominal surgery. Methods: This was a prospective, observational study of patients undergoing major abdominal surgery in a tertiary care center. Postoperative AKI was diagnosed according to the Acute Kidney Injury Network criteria within 48 h after surgery. Patients with chronic kidney disease stage IV or V were excluded. Logistic regression analysis was used to evaluate the association between perioperative factors and the risk of developing postoperative AKI. Results: Eleven out of 61 patients developed postoperative AKI. Four intra-operative variables were identified as predictors of AKI: intra-operative blood loss (p = 0.002), transfusion of fresh frozen plasma (p = 0.004) and red blood cells (p = 0.038), as well as high chloride load (p = 0.033, cut-off value > 500 mEq). Multivariate analysis demonstrated an independent association between AKI development and preoperative albuminuria, defined as a urinary Albumin to Creatinine ratio ≥ 30 mg·g−1 (OR = 6.88, 95% CI: 1.43–33.04, p = 0.016) as well as perioperative chloride load > 500 mEq (OR = 6.87, 95% CI: 1.46–32.4, p = 0.015). Conclusion: Preoperative albuminuria, as well as a high intraoperative chloride load, were identified as predictors of postoperative AKI in patients undergoing major abdominal surgery.

Background: The aim of this study was to examine different definitions of renal recovery following postoperative acute kidney injury (AKI) and how these definitions associate with survival and the development and progression of chronic kidney disease (CKD). Methods: This was a retrospective study of all patients who underwent abdominal, cardiothoracic, vascular, or orthopedic surgery at a single university hospital between 1998 and 2015. Recovery of renal function following postoperative AKI was assessed comparing 4 different definitions: serum creatinine (SCr) (i) < 1.1 × baseline, (ii) 1.1–1.25 × baseline, (iii) 1.25–1.5 × baseline, and (iv) > 1.5 × baseline. One-year survival and the development or progression of CKD within 5 years was compared with a propensity score-matched control groups. Results: In total, 2,520 AKI patients were evaluated for renal recovery. Risk of incident and progressive CKD within 5 years was significantly increased if patients did not achieve a reduction in SCr to < 1.5 × baseline (hazard ratio [HR] 1.50; 95% CI 1.29–1.75) and if renal recovery was limited to a fall in SCr to 1.25–1.5 × baseline (HR 1.32; 95% CI 1.12–1.57) within 30 days. The definition of renal recovery that best predicted survival was a reduction in SCr to < 1.5 × baseline within 30 days. One-year survival of patients whose SCr decreased to < 1.5 × baseline within 30 days was significantly better than that of a propensity score-matched control group that did not achieve renal recovery (85 vs. 71%, p < 0.001). Conclusions: These findings should be considered when a consensus definition of renal recovery after AKI is established.

ABSTRACT: Intermittent hemodialysis (IHD) is a form of renal replacement that is used in veterinary medicine for cases involving drug removal, electrolyte imbalance, acute kidney injury, and chronic kidney disease (CKD). The aim of the present study was to verify the efficacy of IHD in dogs with CKD staged at grade III and to evaluate the effect of IHD on quality of life. Twelve dogs with CKD at stage III met the inclusion criteria and were divided equally into two groups. The control group (n=6) received only clinical treatment and intravenous fluid therapy, and the hemodialysis group (n=6) received clinical and IHD treatments. Blood samples were collected before and after treatments in both groups. We evaluated complications and clinical parameters of IHD every 30 minutes. Hemodialysis decreased serum urea, creatinine, and phosphorus. Despite the evident removal of nitrogen compounds, dialysis treatment did not increase survival time in these patients. The results of this study do not support the early use of dialysis in dogs with chronic kidney disease stage III.

Background Acute kidney injury (AKI) is associated with a dismal prognosis in Transcatheter Aortic Valve replacement (TAVR). Acute kidney recovery (AKR), a phenomenon reverse to AKI has recently been associated with better outcomes. Methods Between November 2012 to May 2018, we explored consecutive patients referred to our Heart Valve Center for TAVR. AKI was defined according to the VARC-2 definition. Mirroring the VARC-2 definition of AKI, AKR was defined as a decrease in serum creatinine (≥50%) or ≥25% improvement in GFR up to 72 hours after TAVR. Results AKI and AKR were respectively observed in 8.3 and 15.7% of the 574 patients included. AKI and AKR patients were associated to more advanced kidney disease at baseline. At a median follow-up of 608 days (range 355–893), AKI and AKR patients experienced an increased cardiovascular mortality compared to unchanged renal function patients (14.6% and 17.8% respectively, vs. 8.1%, CI 95%, p<0.022). Chronic kidney disease, (HR: 3.9; 95% CI 1.7–9.2; p < 0.001) was the strongest independent factor associated with AKI similarly to baseline creatinine level (HR: 1; 95% CI 1 to 1.1 p < 0.001) for AKR. 72-hours post procedural AKR (HR: 2.26; 95% CI 1.14 to 4.88; p = 0.021) was the strongest independent predictor of CV mortality. Conclusions Both AKR and AKI negatively impact long term clinical outcomes of patients undergoing TAVR.

New Biomarkers

Acute kidney injury (AKI) is a common clinical syndrome. Its variety of presentation explains the absence of “kidney troponin”. Many research projects of new biomarkers are ongoing now. The enormous number of biomarkers has been identified already. It makes difficult to choose the correct test and dictates the importance of the fastest and most accurate introduction of AKI biomarkers into clinical practice. The integration of appropriately selected biomarkers in routine clinical practice for high-risk patients of AKI is very important. Currently, serum creatinine (sCr) and urine output are used to define AKI in accordance with the definition of KDIGO (Kidney Disease: Improving Global Outcomes), which have a number of significant limitations for practitioners, including the inability to diagnose AKI before serum creatinine levels increase. Practitioners need systematic information about the latest AKI markers and possible situations, when and for which patient groups they can be used. This is the main goal of our review.

Stage 1

The term acute kidney injury (AKI) has replaced acute renal failure in contemporary medical literature. AKI denotes a rapid deterioration of kidney function within hours to weeks, resulting in the accumulation of nitrogenous metabolites in addition to fluid, electrolyte, and acid-base imbalances. The definition of AKI was refined to a 3-stage definition, with criteria for stage 1 as follows: 1) an absolute increase in serum creatinine (SCr) by at least 0.3 mg/dL from baseline within 48 hours; or 2) a relative increase in SCr to at least 1.5 times baseline within the past 7 days; or 3) urine output decreased to less than 0.5 mL/kg/h for 6 hours.

Early Detection And Prevention

Acute kidney injury (AKI) occurs in 5%-30% of noncritically ill hospitalized children. Initially thought to be simply a symptom of more severe pathologies, it is now recognized that AKI independently increases mortality and is associated with the development of chronic kidney disease (CKD), even in children. The wide acceptance of the Kidney Disease Improving Global Outcome (KDIGO) diagnostic criteria has enabled a more uniform definition of AKI from both clinical and research perspectives. A better understanding of the pathophysiology and risk factors for AKI has led to new methods for early detection and prevention efforts. While serum creatinine (SCr) was historically one of the sole markers of AKI, novel biomarkers can facilitate earlier diagnosis of AKI, identify subclinical AKI, and guide clinical management. This clinical practice update addresses the latest clinical advances in risk assessment, diagnosis, and prevention of pediatric AKI, with a focus on AKI biomarkers.
