The risk of chronic kidney disease (CKD) following severe acute kidney injury (AKI) in critically ill patients is well documented, but not after less severe AKI. The main objective of this study was to evaluate the long-term incidence of CKD after non-severe AKI in critically ill patients. This prospective single-center observational three-years follow-up study was conducted in the medical intensive care unit in Bordeaux’s hospital (France). From 2013 to 2015, all patients with severe (kidney disease improving global outcomes (KDIGO) stage 3) and non-severe AKI (KDIGO stages 1, 2) were enrolled. Patients with prior eGFR < 90 mL/min/1.73 m2 were excluded. Primary outcome was the three-year incidence of CKD stages 3 to 5 in the non-severe AKI group. We enrolled 232 patients. Non-severe AKI was observed in 112 and severe AKI in 120. In the non-severe AKI group, 71 (63%) were male, age was 62 ± 16 years. The reason for admission was sepsis for 56/112 (50%). Sixty-two (55%) patients died and nine (8%) were lost to follow-up. At the end of the follow-up the incidence of CKD was 22% (9/41); Confidence Interval (CI) 95% (9.3–33.60)% in the non-severe AKI group, tending to be significantly lower than in the severe AKI group (44% (14/30); CI 95% (28.8–64.5)%; p = 0.052). The development of CKD three years after non-severe AKI, despite it being lower than after severe AKI, appears to be a frequent event highlighting the need for prolonged follow-up.

Abstract Acute kidney injury (AKI) is associated with tubulointerstitial fibrosis and nephron loss and may lead to an increased risk for subsequently developing chronic kidney disease (CKD). In adults with sickle cell anemia (SCA), high rates of CKD have been consistently observed, although the incidence and risk factors for AKI are less clear. We evaluated the incidence of AKI, defined according to Kidney Disease Improving Global Outcomes (KDIGO) guidelines as a rise in serum creatinine by ≥0.3mg/dL within 48 hours or ≥1.5 times baseline within seven days, in 158 of 299 adult SCA patients enrolled in a longitudinal cohort from the University of Illinois at Chicago. These patients were selected based on the availability of genotyping for α-thalassemia, BCL11A rs1427407, APOL1 G1/G2, and the HMOX1 rs743811 and GT-repeat variants. Median values and interquartile range (IQR) are provided. With a median follow up time of 66 months (IQR, 51-74 months), 137 AKI events were observed in 63 (40%) SCA patients. AKI was most commonly observed in the following settings: acute chest syndrome (25%), an uncomplicated vaso-occlusive crisis (VOC)(24%), a VOC with pre-renal azotemia determined by a fractional excretion of sodium &lt;1% or BUN-to-creatinine ratio &gt;20:1 (14%), or a VOC with increased hemolysis, defined as an increase in serum LDH or indirect bilirubin level &gt;1.5 times over the baseline value at the time of enrollment (12%). Compared to individuals who did not develop AKI, SCA adults who developed an AKI event were older (AKI: median and IQR age of 35 (26-46) years, no AKI: 28 (23 - 26) years; P=0.01) and had a lower estimated glomerular filtration rate (eGFR) (AKI: median and IQR eGFR of 123 (88-150) mL/min/1.73m2, no AKI: 141 (118-154) mL/min/1.73m2; P=0.02) by the Kruskal-Wallis test at the time of enrollment. We evaluated the association of a panel of candidate gene variants with the risk of developing an AKI event. These included loci related to the degree of hemolysis (α-thalassemia, BCL11A rs1427407), to chronic kidney disease (APOL1 G1/G2 risk variants), and to heme metabolism (HMOX1) . Using a logistic regression model that adjusted for age and eGFR at the time of enrollment, the risk of an AKI event was associated with older age (10-year OR 2.6, 95%CI 1.4-4.8, P=0.002), HMOX1 rs743811 (OR 3.1, 95%CI 1.1-8.7, P=0.03), and long HMOX1 GT-repeats, defined as &gt;25 repeats (OR 2.5, 95%CI 1.01-6.1, P=0.04). Next, we assessed whether AKI is associated with a more rapid decline in eGFR and with CKD progression, defined as a 50% reduction in eGFR, on longitudinal follow up. Using a mixed effects model that adjusted for age and eGFR at the time of enrollment, the rate of eGFR decline was significantly greater in those with an AKI event (β = -0.51) vs. no AKI event (β = -0.16) (P=0.03). With a median follow up time of 66 months (IQR, 51-74 months), CKD progression was observed in 21% (13/61) of SCA patients with an AKI event versus 9% (8/88) without an AKI event. After adjusting for age and eGFR at the time of enrollment, the severity of an AKI event according to KDIGO guidelines (stage 1 if serum creatinine rises 1.5-1.9 times baseline, stage 2 if the rise is 2.0-2.9 times baseline, and stage 3 if the rise is ≥3 times baseline or ≥4.0 mg/dL or requires renal replacement therapy) was a risk factor for CKD progression (unadjusted HR 1.6, 95%CI 1.1-2.3, P=0.02; age- and eGFR-adjusted HR 1.6, 95%CI 1.1-2.5, P=0.03). In conclusion, AKI is commonly observed in adults with sickle cell anemia and is associated with increasing age and the HMOX1 GT-repeat and rs743811 polymorphisms. Furthermore, AKI may be associated with a steeper decline in kidney function and more severe AKI events may be a risk factor for subsequent CKD progression in SCA. Future studies understanding the mechanisms, consequences of AKI on long-term kidney function, and therapies to prevent AKI in SCA are warranted.

Chronic kidney disease is a global health burden, with an estimated prevalence of 11–13%, with the majority of patients diagnosed as stage 3, and is an independent risk factor for cardiovascular disease. The incidence of acute kidney injury is increasing, and estimated to be present in one in five acute hospital admissions, and there is a bidirectional relationship between acute and chronic kidney disease. The relevance to the patient with cardiovascular disease relates to increased perioperative risk, as reduced kidney function is an independent risk factor for adverse postoperative cardiovascular outcomes including myocardial infarction, stroke, and progression of heart failure. Furthermore, patients undergoing cardiovascular investigations are at risk of developing acute kidney injury, in particular where iodinated contrast is administered. This chapter reviews the classification of renal disease and its impact on cardiovascular disease, as well as potential methods for reducing the development of contrast-induced acute kidney injury.

Background: The progression from acute kidney injury (AKI) to chronic kidney disease (CKD) is not well understood in children. Objectives: We aimed to develop a pediatric CKD definition using administrative data and use it to evaluate the association between AKI in critically ill children and CKD 5 years after hospital discharge. Design: Retrospective cohort study using chart collection and administrative data. Setting: Two-center study in Montreal, Canada. Patients: Children (≤18 years old) admitted to two pediatric intensive care units (ICUs) between 2003 and 2005. We a priori excluded patients with end-stage renal disease or no health care number. Only the first admission during the study period was included. We excluded patients who could not be linked to administrative data, did not survive hospitalization, or had preexisting renal disease. Measurements: Acute kidney injury was defined using Kidney Disease: Improving Global Outcomes (KDIGO) criteria. Patients were defined as having CKD 5 years post-discharge if they had ≥1 CKD diagnostic code or ≥1 CKD-specific medication prescription. Methods: Chart data used to define the exposure (AKI) were merged with provincial administrative data used to define the outcome (CKD). Cox regression was used to evaluate the AKI-CKD association. Results: A total of 2235 (56% male) patients were included, and the median admission age was 3.7 years. A total of 464 (21%) patients developed AKI during pediatric ICU admission. At 5 years post-discharge, 43 (2%) patients had a CKD diagnosis. Patients with both stage 1 and stage 2-3 AKI had increased risk of a CKD diagnosis, with the adjusted hazard ratios (95% confidence intervals) of 2.2 (1.1-4.5) and 2.5 (1.1-5.7), respectively ( P < .001). Limitations: Results may not be generalizable to non-ICU patients. We were not able to control for post-discharge variables; future research should try to explore these additional potential risk factors further. Conclusions: Acute kidney injury is associated with 5-year post-discharge CKD diagnosis defined by administrative health care data.

Purpose: Acute kidney injury (AKI) is a severe complication in medical and surgical intensive care units accounting for a high morbidity and mortality. Incidence, risk factors, and prognostic impact of this deleterious condition are well established in this setting. Data concerning the neurocritically ill patients is scarce. Therefore, aim of this study was to determine the incidence of AKI and elucidate risk factors in this special population. Methods: Patients admitted to a specialized neurocritical care unit between 2005 and 2011 with a length of stay above 48 hours were analyzed retrospectively for incidence, cause, and outcome of AKI (AKI Network-stage ≥2). Results: The study population comprised 681 neurocritically ill patients from a mixed neurosurgical and neurological intensive care unit. The prevalence of chronic kidney disease (CKD) was 8.4% (57/681). Overall incidence of AKI was 11.6% with 36 (45.6%) patients developing dialysis-requiring AKI. Sepsis was the main cause of AKI in nearly 50% of patients. Acute kidney injury and renal replacement therapy are independent predictors of worse outcome (hazard ratio [HR]: 3.704; 95% confidence interval [CI]: 1.867-7.350; P < .001; and HR: 2.848; CI: 1.301-6.325; P = .009). Chronic kidney disease was the strongest independent risk factor (odds ratio: 12.473; CI: 5.944-26.172; P < .001), whereas surgical intervention or contrast agents were not associated with AKI. Conclusions: Acute kidney injury in neurocritical care has a high incidence and is a crucial risk factor for mortality independently of the underlying neurocritical condition. Sepsis is the main cause of AKI in this setting. Therefore, careful prevention of infectious complications and considering CKD in treatment decisions may lower the incidence of AKI and hereby improve outcome in neurocritical care.

Acute kidney injury is a common disease that affects critically ill patients and increases morbidity and mortality. Even though there have been extensive efforts to prevent this disease, the incidence has steadily increased over the last decade. This could be attributed to better recognition or to overestimation of the disease based on the most recent consensus criteria. Complications of acute kidney injury have a significant effect on quality of life, morbidity, and mortality. Despite advances in the field, this disease continues to be a challenge, and decreasing the mortality associated with it remains difficult. Plenty of literature has been published about the appropriate definition, diagnosis, and treatment of the disease. One of the topics of ongoing discussion deals with the lack of consensus about the exact timing for initiation of renal replacement therapy (RRT). Even though RRT adds more complexity to the treatment, recent publications suggest that early versus late initiation of RRT is related to reduced mortality in critically ill patients. Further high-level studies of this intervention are warranted to standardize treatment. This review contains 5 figures, 7 tables, and 77 references.               Key words: Acute Kidney Injury Network (AKIN), acute kidney injury, chronic kidney disease, Kidney Disease: Improving Global Outcomes (KDIGO), renal biomarkers, replacement therapy, Risk, Injury, Failure, Loss of kidney function and End-stage kidney disease (RIFLE)
