Acute kidney injury (AKI) is a syndrome of reduced glomerular filtration rate (GFR) 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 5254 differentially expressed genes in at least one of the AKI models...

Introduction: Single-center and observational studies have suggested that calcium channel blocking agents may decrease the expression of sepsis in individual populations. In the renal transplant population, a role for calcium channel blockers in allograft protection and in prevention of sepsis has been postulated. We hypothesized that any important survival benefit or risk related to chronic use of calcium channel blocking agents should be discernable through an analysis of a large database of stable recipients of renal allografts who had enrolled in a large international trial...

INTRODUCTION: There are numerous reports in the literature describing acute kidney injury in pregnancy (P-AKI) due to various obstetric complications. However, there is a dearth of studies on AKI related to pregnancy-specific disorders from India. We aimed to analyze clinical features and outcome of P-AKI related to pregnancy-specific disorders compared to total pregnancy, in India. METHOD: All pregnant women attending the department of Obstetrics and Gynecology from November 2014 to July 2016 were screened for AKI based on: (1) sudden elevation of serum creatinine ≥ 1 mg/dl; (2) oligoanuria for > 12 h; and (3) need for dialysis...

Sepsis is a serious medical condition that can lead to multi-organ failure and shock, and it is associated with increased mortality. Acute kidney injury (AKI) is a frequent complication of sepsis in critically ill patients, and often requires renal replacement therapy. The pathophysiology of AKI in sepsis has not yet been fully defined. In the past, classic theories were mainly focused on systemic hemodynamic derangements, underscoring the key role of whole kidney hypoperfusion due to reduced renal blood flow...

Acute kidney injury (AKI) remains one of the main causes of morbidity and mortality in the intensive care medicine today. Its pathophysiology and progress to chronic kidney disease is still under investigation. In addition, the lack of techniques to adequately monitor renal function and microcirculation at the bedside makes its therapeutic resolution challenging. In this article, we review current concepts related to renal hemodynamics compromise as being the event underlying AKI. In doing so, we discuss the physiology of the renal circulation and the effects of alterations in systemic hemodynamics that lead to renal injury specifically in the context of reperfusion injury and sepsis...

PURPOSE: Acute kidney injury (AKI) is a severe complication after infrarenal abdominal aortic aneurysm (iAAA) repair. Little data are available whether endovascular aneurysm (EVAR) or open aortic repair (OAR) differs with respect to AKI frequency and severity, consecutive development of chronic kidney disease (CKD) and potentially preventable and modifiable risk factors of AKI. PATIENTS AND METHODS: We assessed AKI rates, AKI stages and CKD applying current, complete definitions from the kidney disease improving global outcomes initiative in propensity-score-matched cohorts of all patients with elective and urgent iAAA repair at our institution from 2007 to 2011...

Delayed bowel erosion by peritoneal dialysis catheter is rare with fewer than thirty cases having been reported in the literature. This complication is usually encountered when the catheter is kept dormant. Two cases have also been reported with catheters in active use. The risk factors for bowel erosion include immunosuppression, diverticulosis, and amyloidosis. An 80-year-old male with chronic kidney disease Stage 5 due to hypertensive nephrosclerosis underwent chronic ambulatory peritoneal dialysis catheter insertion...

IgA-dominant infection-related glomerulonephritis (IRGN) is a distinct morphologic variant of IRGN, characterized by dominant or codominant glomerular deposits of IgA, mostly in elderly and patients with diabetes. More cases are being reported in recent times due to increased awareness of the disease entity and increased rate of Staphylococcus infection. It usually presents as rapidly progressive renal failure with proteinuria, and treatment guidelines for this disease entity are not well defined. We report here 12 cases of IgA-dominant IRGN seen over a period of 5 years from a single center...

BACKGROUND: Arteriovenous graft (AVG) infections can present as major life-threatening hemorrhage or sepsis in a chronic kidney disease patient. Frequently, all these patients present in critical condition which need prompt and expeditious management. Various procedures are described for management of infected grafts and its bleeding complications. However, these procedures are associated with postop-operative bleeding and persistent infection. The aim was to study brachial artery ligation (BAL) near the elbow joint in the management of an infected AVG...

Growth differentiation factor-15 (GDF-15) is a member of the transforming growth factor-β superfamily related to inflammation and macrophage activation. Serum concentrations of GDF-15 can predict poor survival in chronic diseases, but its role in sepsis is obscure. Therefore, we investigated GDF-15 as a prognostic biomarker in critically ill patients. We measured GDF-15 levels in 219 critically ill patients (146 with sepsis, 73 without sepsis) upon admission to the intensive care unit (ICU), in comparison to 66 healthy controls...

Simultaneous assessment of excretory liver and kidney function is still an unmet need in experimental stress models as well as in critical care. The aim of the study was to characterize two polymethine-dyes potentially suitable for this purpose in vivo. Plasma disappearance rate and elimination measurements of simultaneously injected fluorescent dyes DY-780 (hepato-biliary elimination) and DY-654(renal elimination) were conducted using catheter techniques and intravital microscopy in animals subjected to different organ injuries, i...

With the adoption of the new definition and classification of cardiorenal syndrome (CRS) and its relevant subtypes, much attention has been placed on elucidating the mechanisms of heart and kidney interactions. The pathophysiologic pathways are of great interest by which acute heart failure may result in acute kidney injury (AKI; type 1), chronic heart failure accelerates the progression of chronic kidney disease (CKD; type 2), AKI provokes cardiac events (type 3), and CKD increases the risk and severity of cardiovascular disease (type 4)...
