Acute kidney injury (AKI) is one of the most common serious complications for all hospital admissions, with its incidence increasing among hospitalized patients, particularly those in the intensive care unit. Despite significant improvements in critical care and dialysis technology, AKI is associated with an increased risk of short- and long-term mortality, prolonged hospital stays, and dialysis dependence. These risks are particularly relevant for critically ill patients with AKI severe enough to require renal replacement therapy (RRT)...

PURPOSE OF REVIEW: Recent epidemiological and preclinical mechanistic studies provide strong evidence that acute kidney injury (AKI) and chronic kidney disease (CKD) form an interconnected syndrome. Injured kidneys undergo a coordinated reparative process with an engagement of multiple cell types after injury; however, maladaptation to the injury subjects kidneys to a vicious cycle of fibrogenesis and nephron loss. In this review, we will outline and discuss the pathogenesis of AKI-to-CKD transition with an emphasis on dysregulated 'cellular stress adaptation' as a potential therapeutic target...

BACKGROUND: The incidence of acute kidney injury (AKI) is increasing. AKI is currently recognised as an inducer of chronic kidney disease (CKD) and this is known as the 'AKI-CKD transition'. This study aimed to evaluate the rate of decline in estimated glomerular filtration rate (eGFR) associated with AKI events in individuals with and without pre-existing CKD. METHODS: Inpatients aged 18-80 years were retrospectively enrolled. AKI was diagnosed according to the kidney disease improving global outcomes (KDIGO) criteria using serum creatinine levels...

Importance: Some patients will develop chronic kidney disease after a hospitalization with acute kidney injury; however, no risk-prediction tools have been developed to identify high-risk patients requiring follow-up. Objective: To derive and validate predictive models for progression of acute kidney injury to advanced chronic kidney disease. Design, Setting, and Participants: Data from 2 population-based cohorts of patients with a prehospitalization estimated glomerular filtration rate (eGFR) of more than 45 mL/min/1...

The increasing use of extended criteria organs to meet the demand for kidney transplantation raises an important question of how the severity of early ischaemic injury influences long-term outcomes. Significant acute ischaemic kidney injury is associated with delayed graft function, increased immune-associated events and, ultimately, earlier deterioration of graft function. A comprehensive understanding of immediate molecular events that ensue post-ischaemia and their potential long-term consequences are key to the discovery of novel therapeutic targets...

Diabetic kidney disease, commonly termed diabetic nephropathy (DN), is the most common cause of end-stage kidney disease (ESKD) worldwide. The characteristic histopathology of DN includes glomerular basement membrane thickening, mesangial expansion, nodular glomerular sclerosis, and tubulointerstitial fibrosis. Diabetes is associated with a number of metabolic derangements, such as reactive oxygen species overproduction, hypoxic state, mitochondrial dysfunction, and inflammation. In the past few decades, our knowledge of DN has advanced considerably although much needs to be learned...

PURPOSE: To evaluate 1-year mortality in patients with septic acute kidney injury (AKI) and to determine association between initial AKI recovery patterns ( reversal within 5 days, beyond 5 days but recovery, or nonrecovery) and chronic kidney disease (CKD) progression. METHODS: Prospective observational study, with retrospective evaluation of initial nonconsenters, of critically ill patients with septic AKI. RESULTS: We studied 207 patients (age, mean [SD]: 64 [16] years, 39% males), of which 56 (27%), 18 (9%), and 9 (4%) died in intensive care unit (ICU), post-ICU in hospital, and posthospitalization, respectively...

Dialysis care in the United States continues to move toward an emphasis on continuous quality improvement and performance benchmarking. Government- and industry-sponsored programs have evolved to assess and incentivize outcomes for many components of end-stage renal disease care. One aspect that remains largely unaddressed at a systemic level is the high-risk transition period from chronic kidney disease and acute kidney injury to permanent dialysis dependence. Incident dialysis patients experience disproportionately high mortality and hospitalization rates coupled with high costs...

Acute kidney injury (AKI) is a heterogeneous disorder that is common in hospitalized patients and associated with short- and long-term morbidity and mortality. When AKI is present, prompt workup of the underlying cause should be pursued, with specific attention to reversible causes. Measures to prevent AKI include optimization of volume status and avoidance of nephrotoxic medications. Crystalloids are preferred over colloids for most patients, and hydroxyethyl starches should be avoided. Volume overload in the setting of AKI is associated with adverse outcomes, so attention should be paid to overall fluid balance...

BACKGROUND: Acute kidney injury (AKI), even if followed by renal recovery, is a risk factor for the future development of chronic kidney disease (CKD) and end-stage renal disease (ESRD). In the previous years, novel insights in the pathophysiology of CKD progression suggested a causal link between AKI and CKD due to a maladaptive repair after severe and repeated injury. SUMMARY: Several pathological mechanisms have been proposed to contribute to the progression of AKI and transition to CKD/ESRD including hypoxia and microvascular rarefaction, alterations of renal resident cell phenotypes and functions, cell cycle arrest in the G2/M phase, persistent chronic inflammation, and development of interstitial fibrosis, mitochondrial fragmentation, epigenetic changes, activation of renin-angiotensin system (RAS), cell and tissue senescence...

Acute kidney injury (AKI) is characterized clinically as an abrupt decline in renal function marked by reduced excretion of waste products, disordered electrolytes, and disrupted fluid homeostasis. The recent development of a standardized AKI definition has transformed our understanding of AKI epidemiology and outcomes. We now know that in the short term, children with AKI experience greater morbidity and mortality; additionally, observational studies have established that chronic renal sequelae are far more common after AKI events than previously realized...

Renal tubules are the major component of the kidney and are vulnerable to a variety of injuries including hypoxia, proteinuria, toxins, metabolic disorders, and senescence. It has long been believed that tubules are the victim of injury. In this review, we shift this concept to renal tubules as a driving force in the progression of kidney diseases. In response to injury, tubular epithelial cells undergo changes and function as inflammatory and fibrogenic cells, with the consequent production of various bioactive molecules that drive interstitial inflammation and fibrosis...

Oxidative stress and mitochondrial dysfunction exacerbate acute kidney injury (AKI), but their role in any associated progress to chronic kidney disease (CKD) remains unclear. Antioxidant therapies often benefit AKI, but their benefits in CKD are controversial since clinical and preclinical investigations often conflict. Here we examined the influence of the antioxidant N-acetyl-cysteine (NAC) on oxidative stress and mitochondrial function during AKI (20-min bilateral renal ischemia plus reperfusion/IR) and progression to chronic kidney pathologies in mice...

Acute kidney injury (AKI) is a syndrome of reduced glomerular filtration rate and urine production caused by a number of different diseases. It is associated with renal tissue damage. This tissue damage can cause tubular atrophy and interstitial fibrosis that leads to nephron loss and progression of chronic kidney disease (CKD). This review describes the in-common mechanisms behind tissue damage in AKI caused by different underlying diseases. Comparing six high-quality microarray studies of renal gene expression after AKI in disease models (gram-negative sepsis, gram-positive sepsis, ischemia-reperfusion, malignant hypertension, rhabdomyolysis, and cisplatin toxicity) identified 5,254 differentially expressed genes in at least one of the AKI models; 66% of genes were found only in one model, showing that there are unique features to AKI depending on the underlying disease...

BACKGROUND: The optimal time to initiate renal replacement therapy (RRT) in intensive care unit (ICU) patients with acute kidney injury (AKI) is unclear. We examined the impact of early RRT on long-term mortality, risk of chronic kidney disease (CKD), and end-stage renal disease (ESRD). METHODS: This cohort study included all adult patients treated with continuous RRT in the ICU at Aarhus University Hospital, Skejby, Denmark (2005-2015). Data were obtained from a clinical information system and population-based registries...

Large epidemiologic studies in a variety of patient populations reveal increased morbidity and mortality that occur months to years after an episode of acute kidney injury (AKI). Even milder forms of AKI have increased associated morbidity and mortality. Residual confounding may account for these findings, but considering the huge number of individuals afflicted with AKI, the sequelae of AKI may be a very large public health burden. AKI may simply be a marker for increased risk, but there is increasing evidence that it is part of the causal pathway to chronic kidney disease...

Tissue hypoxia has been proposed as an important factor in the pathophysiology of both chronic kidney disease (CKD) and acute kidney injury (AKI), initiating and propagating a vicious cycle of tubular injury, vascular rarefaction, and fibrosis and thus exacerbation of hypoxia. Here, we critically evaluate this proposition by systematically reviewing the literature relevant to the following six questions: (i) Is kidney disease always associated with tissue hypoxia? (ii) Does tissue hypoxia drive signalling cascades that lead to tissue damage and dysfunction? (iii) Does tissue hypoxia per se lead to kidney disease? (iv) Does tissue hypoxia precede pathology? (v) Does tissue hypoxia colocalize with pathology? (vi) Does prevention of tissue hypoxia prevent kidney disease? We conclude that tissue hypoxia is a common feature of both AKI and CKD...

The proximal tubule epithelium relies on mitochondrial function for energy, rendering the kidney highly susceptible to ischemic AKI. Dynamin-related protein 1 (DRP1), a mediator of mitochondrial fission, regulates mitochondrial function; however, the cell-specific and temporal role of DRP1 in AKI in vivo is unknown. Using genetic murine models, we found that proximal tubule-specific deletion of Drp1 prevented the renal ischemia-reperfusion-induced kidney injury, inflammation, and programmed cell death observed in wild-type mice and promoted epithelial recovery, which associated with activation of the renoprotective β -hydroxybutyrate signaling pathway...

Acute kidney injury (AKI) occurs in approximately 10% to 15% of hospital-admitted patients and is associated with in-hospital mortality of 50% in patients requiring renal replacement therapy. Recently, multiple observational studies have demonstrated that patients who survive AKI have significant long-term consequences including cardiovascular events, progression to advanced-stage chronic kidney disease (CKD), and mortality. A direct link between AKI and CKD is provided by studies that demonstrate that some patients with normal renal function who develop AKI requiring dialysis never recover...
