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. Keywords: Kidney, renal, KDIGO, azotemia, critical, urine, oliguria, creatinine, dialysis

Background: Acute kidney injury occurring during pregnancy, labour, delivery, and/or postpartum period. Proper management of AKI (acute kidney injury) is challenging because (i) both maternal and fetal health must be considered and (ii) the cardiovascular and renal adaptations of pregnancy add to the complexity for management.Methods: The objective of this study was to study association and contributing factors in AKI, a retrospective study of 20 cases of AKI complicating pregnancies carried out in department of obstetrics and gynecology, SVPIMSR over a period of 12 months and results were studied and analysed. Etiological factors, associated liver pathology, coagulation abnormality, thrombocytopenia, sepsis, recovery status and fetomaternal outcome were studied and tabulated. AKI was analysed in terms of maximal stage of renal injury attained as per risk, injury, failure, loss of function, and end-stage renal disease (RIFLE) criteria.Results: The incidence of ARF (acute renal failure) in pregnancy was about 0.3%. Hypertensive disorders were the major causative factor. Amongst the 20 cases, 8 cases were referred from outside and two of them died. Total 5 of 20 cases required hemodialysis and two of them had partial recovery.Conclusions: AKI complicating pregnancies are not uncommon. If recognized and treated promptly, recovery is assured in majority of cases. Early identification and prompt management of pre-eclampsia and sepsis can prevent majority of cases. Ultrasonography revelation of placenta previa or abruption helps in early management eventually decreases the chances of bleeding which is one of the causes of AKI (pre-renal cause).

Background/Aims: Delivered dialysis therapy is routinely measured in the management of patients with end-stage renal disease; yet, the quantification of renal replacement prescription and delivery in acute kidney injury (AKI) is less established. While continuous renal replacement therapy (CRRT) is widely understood to have greater solute clearance capabilities relative to intermittent therapies, neither urea nor any other solute is specifically employed for CRRT dose assessments in clinical practice at present. Instead, the normalized effluent rate is the gold standard for CRRT dosing, although this parameter does not provide an accurate estimation of actual solute clearance for different modalities. Methods: Because this situation has created confusion among clinicians, we reappraise dose prescription and delivery for CRRT. Results: A critical review of RRT quantification in AKI is provided. Conclusion: We propose an adaptation of a maintenance dialysis parameter (standard Kt/V) as a benchmark to supplement effluent-based dosing of CRRT.

In peritoneal dialysis (PD), the peritoneum serves as a biological dialyzing membrane. The endothelium of the vast capillary network perfusing the peritoneum functions as a semipermeable membrane and allows bidirectional solute and water transfer between the intravascular space and dialysate fluid dwelling in the peritoneal cavity. PD is a renal replacement strategy for patients presenting with end-stage renal disease. It can also be offered for ultrafiltration in patients with diuretic-resistant fluid overload even in those without advanced renal failure. PD can also be used for patients with acute kidney injury, although in the developed world this occurs rarely compared to the use of extracorporeal therapies. This review contains 9 videos,  8 figures, 4 tables, and 73 references.  Keywords: peritoneal dialysis, peritoneal cavity, catheter, dialysis fluid, ultrafiltration, tunnel infection, osmotic pressure, renal failure

Abstract Background and Aims Acute post-infectious glomerulonephritis (APIGN) is a reactive immunological disease. Its prevalence in industrialized countries is declining contrasting with developed ones. It is uncommon in adults but the prognosis may be reserved. The aim of our study was to evaluate the epidemiological, clinical and histological features of APIGN as well as its prognosis. Method A retrospective and descriptive study was conducted in our department. Were included all cases of histologically proven APIGN between December 2006 and December 2017. Results We had collected 38 cases. The mean age was 37.7 ± 17.8 years. The sex ratio was 1.92. Twelve (31.6%) patients were diabetic and four of them had already a chronic kidney disease (CKD). APIGN was preceded by an infection in 27 cases with an average interval of 10 ± 5 days. The most common site of infection was the respiratory tract (15 cases). At presentation, 27 patients had nephritic syndrome and 13 had nephrotic-range proteinuria. Hematuria was observed in 97.4%, peripheral edema in 84.2% and hypertension in 73.7% of cases. Most patients (78.9%) had acute kidney injury and 10 (26.3%) patients required dialysis. Renal biopsy had shown benign acute glomerulonephritis in 31 cases and malignant form in 7 cases. An underlying nephropathy was found in 12 cases with mostly a diabetic nephropathy. Corticosteroids were used in 3 cases of benign APIGN and 5 cases of malignant form. During the follow-up, CKD was noted in 14(36.8%) patients including 7(18.4%) patients who progressed to end-stage renal disease. Poor prognostic factors were diabetes, the presence of an underlying nephropathy in the biopsy, acute kidney injury and the need for dialysis. Conclusion The APIGN is uncommon in adults, yet its prognosis may be reserved with progression to CKD.

Background: Acute Kidney Injury (AKI) is an abrupt decrease in kidney function, leading to the retention of urea and other nitrogenous waste products. Poisoned patients admitted to the Intensive Care Unit (ICU) may develop AKI due to some reasons. This study was done to evaluate the AKI in poisoned patients admitted to ICU. Methods: 146 patients, admitted to the ICU of Imam Reza Hospital from March 2017 to March 2018 were studied. AKI status was assessed using Acute Kidney Injury Network (AKIN) and Risk, Injury, Failure, Loss of kidney function and End-stage kidney disease (RIFLE) classification. Data analysis was done through SPSS V. 22 software. Results: Opioids, organophosphates, aluminum phosphide, multiple drugs, and other types of poisoning were the main five poisoning classes. Opioid toxicity was had the highest frequency with 51 patients; cases in this group experienced longer length of hospitalization stay and higher serum creatinine level than others did. Among 146 patients, 19 patients (12.8%) died, and 97 patients (66%) were transferred to the ICU. Of all cases, 18 patients (12.3%) had renal dysfunction (six patients were at risk, five patient at injury, and seven patients were at failure phase based on the RIFLE criteria). Renal replacement therapy was required in 24 cases (16.4%). Conclusion: It is unlikely to detect a significant difference in the occurrence of AKI between the main poisoning classes. Being the largest group of intoxicated patients admitted to the ICU, the opioid poisoning had the highest rate of AKI
