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...

Acute myocardial infarction (AMI) is more frequently observed in patients with chronic kidney disease (CKD) than in patients without CKD. Initial treatment strategy for AMI includes primary percutaneous coronary intervention (PCI), which requires substantial amount of contrast media. We hypothesized that the clinical outcomes are comparable or worse in patients with AMI and advanced CKD off chronic hemodialysis as compared to patients with AMI and advanced CKD on chronic hemodialysis. The purpose of this study was to compare the clinical outcomes of patients with AMI and advanced CKD on hemodialysis versus off hemodialysis...

OBJECTIVES: To investigate whether measured glomerular filtration rate (mGFR) is a risk factor for death and/or end-stage renal disease (ESRD) after heart transplantation (HTx). METHODS: All adult patients (n = 416) who underwent HTx between 1988 and 2010 were included. mGFR was performed both preoperatively and postoperatively as annual follow-up. Eight patients received a concomitant kidney transplant (KTx), and 15 underwent late KTx due to chronic renal failure after HTx...

Tolvaptan (TLV) has an inhibiting effect for worsening renal function (WRF) in acute decompensated heart failure (HF) patients. However, there are limited data regarding the effect of continuous TLV administration on medium-term WRF.This was a retrospective observational study in hospitalized HF patients with chronic kidney disease (CKD). TLV was administered to those patients with fluid retention despite standard HF therapy. We compared 34 patients treated with TLV (TLV group) to 33 patients treated with conventional HF therapy with high-dose loop diuretics (furosemide ≥ 40 mg) (Loop group)...

BACKGROUND: Although a successful kidney transplant (KTx) improves most of the mineral and bone disorders (MBD) produced by chronic kidney disease (CKD), hyperparathyroidism may persist (pHPT). Current guidelines recommend parathyroidectomy if serum parathormone is persistently elevated 1 year after KTx, because pHPT has been recently associated with poor graft outcomes. However, whether patients with pHPT and adequate renal function are at risk for long-term graft failure is unknown...

Renal ischemia-reperfusion injury (IRI) induces local inflammation leading to kidney damage. Since pentoxifylline (PTX) and steroids have distinct immunomodulatory properties, we aimed to evaluate for the first time their combined use in IRI-induced acute kidney injury (AKI) and chronic kidney disease (CKD) in rats. In two experiments, PTX (100 mg/kg body weight subcutaneously) was administered 90 min prior to renal IRI or/and methylprednisolone (MP; 100 mg/kg body weight intramuscularly) was infused 60 min after reperfusion of a solitary kidney (AKI model: 45 min ischemia, 48 male Sprague-Dawley rats) or one kidney with excision of contralateral kidney 2 weeks later (CKD model: 90 min ischemia, 38 rats)...

Hematopoietic stem cell transplantation (SCT) recipients are exposed to a large amount of anti-cancer drugs, immunosuppressors, and irradiation during the peri-SCT period. Thus, they have to overcome serious adverse events related to unavoidable but toxic procedures, including organ disorders. In particular, acute kidney injury (AKI) is one of the most critical complications, because it influences the mortality of patients. A few patients who survive AKI may develop nephrotic syndrome, and precedent AKI is also closely associated with chronic and progressive loss of the renal function in post-SCT patients...

Defects in tryptophan metabolism on the l-kynurenine pathway (KP) are implicated in a number of human diseases, including chronic kidney disease, brain edema or injury, tuberculosis and malaria - as well as cancer, neurodegenerative and autoimmune disorders. However, it is unclear to what extent detrimental effects of exposure to tryptophan metabolites might impact the early development of organism. Thus, this study examined the effects of KP exposure in zebrafish embryos starting at the blastula period (4hpf) and the segmentation stage (24hpf)...

REVIEW
J McKinlay, E Tyson, L G Forni
Peri-operative acute kidney injury is common, accounting for 30-40% of all in-hospital cases of acute kidney injury. It is associated with clinically significant morbidity and mortality even with what was hitherto regarded as relatively trivial increases in serum creatinine, and carries over a 12-fold relative risk of death following major abdominal surgery. Comorbid conditions such as diabetes, hypertension, liver disease and particularly pre-existing chronic kidney disease, as well as the type and urgency of surgery, are major risk factors for the development of postoperative acute kidney injury...

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...

INTRODUCTION: Patients who develop acute kidney injury (AKI) have an increased risk for progression to chronic kidney disease, end-stage renal disease, and increased mortality. The outcomes of total knee arthroplasty (TKA) patients who develop AKI have remained controversial. The purpose of this review was to summarize and identify the current literature focused on 1) major risk factors, 2) short-term outcomes, and 3) costs associated with the development of perioperative AKI after TKA...

The incidence of acute kidney injury (AKI) and its impact on chronic kidney disease (CKD) following pediatric non-kidney solid organ transplantation is unknown. We aimed to determine the incidence of AKI and CKD and examine their relationship among children who received a heart, lung, liver or multi-organ transplant at the Hospital for Sick Children between 2002 and 2011. AKI was assessed in the first year post-transplant. Among 303 children, perioperative AKI (within the first week) occurred in 67% of children, and AKI after the first week occurred in 36%, with the highest incidence among lung and multi-organ recipients...
