BACKGROUND: This study assessed the ability of 3-hour postoperative urinary tissue inhibitor of metalloproteinases-2 × insulin-like growth factor binding protein-7 ([TIMP-2] × [IGFBP-7]) to predict postoperative acute kidney injury (AKI) in patients undergoing cardiopulmonary bypass during cardiac surgery. METHODS: Patients undergoing cardiac surgery with cardiopulmonary bypass were eligible for this study. Patients with initial chronic renal insufficiency requiring renal replacement therapy, patients <18 years of age, and parturients were not included...

In Africa, the combination of noncommunicable diseases, infectious diseases, exposure to environmental toxins, and acute kidney injury related to trauma and childbirth are driving an epidemic of chronic kidney disease and end-stage renal disease (ESRD). Good registry data can inform the planning of renal services and can be used to argue for better resource allocation, audit the delivery and quality of care, and monitor the impact of interventions. Few African countries have established renal registries and most have failed owing to resource constraints...

BACKGROUND: National levels of personal health-care access and quality can be approximated by measuring mortality rates from causes that should not be fatal in the presence of effective medical care (ie, amenable mortality). Previous analyses of mortality amenable to health care only focused on high-income countries and faced several methodological challenges. In the present analysis, we use the highly standardised cause of death and risk factor estimates generated through the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) to improve and expand the quantification of personal health-care access and quality for 195 countries and territories from 1990 to 2015...

BACKGROUND: Renal involvement in Fabry disease is a major determinant of overall disease prognosis and early enzyme replacement therapy seems effective in preventing progression of kidney injury. Gb3 storage, glomerular sclerosis and tubulo-interstitial fibrosis may occur with minimal or no changes on standard renal tests, hence alternative markers of renal dysfunction are crucial. In this study we compared several biomarkers with albuminuria in the identification of incipient Fabry nephropathy and their diagnostic accuracy to identify chronic kidney disease (CKD) stage≥2...

BACKGROUND: Whether metformin precipitates lactic acidosis in patients with chronic kidney disease (CKD) remains under debate. We examined whether metformin use was associated with an increased risk of acute kidney injury (AKI) as a proxy for lactic acidosis and whether survival among those with AKI varied by metformin exposure. METHODS: All individuals with type 2 diabetes and available prescribing data between 2004 and 2013 in Tayside, Scotland were included. The electronic health record for diabetes which includes issued prescriptions was linked to laboratory biochemistry, hospital admission, death register and Scottish Renal Registry data...

We aimed to identify novel molecular associations between chronic intermittent hypoxia with re-oxygenation and adverse consequences in obstructive sleep apnea (OSA). We analyzed gene expression profiles of peripheral blood mononuclear cells from 48 patients with sleep-disordered breathing stratified into four groups: primary snoring (PS), moderate to severe OSA (MSO), very severe OSA (VSO), and very severe OSA patients on long-term continuous positive airway pressure treatment (VSOC). Comparisons of the microarray gene expression data identified eight genes up-regulated with OSA and down-regulated with CPAP treatment, and five genes down-regulated with OSA and up-regulated with CPAP treatment...

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is an anti-retroviral agent frequently used to treat human immunodeficiency virus (HIV). There are concerns regarding its potential to cause acute kidney injury, chronic kidney disease, and proximal tubulopathy. Although TDF can effectively suppress HIV after kidney transplantation, it is unknown whether use of TDF-based anti-retroviral therapy (ART) after kidney transplant (KT) adversely affects allograft survival. METHODS: We examined 104 HIV+ KT recipients at our center between 2001 and 2014...

Thrombotic microangiopathy (TMA) occurring after acute pancreatitis is rarely described. Without prompt intervention, TMA can be, and often is, lethal, so prompt recognition is important. Here, we present a case of a 61-year-old woman with a history of alcohol misuse who presented with epigastric pain, nausea and vomiting after binge drinking. Elevated serum lipase and imaging were suggestive of acute-on-chronic pancreatitis. Although the patient's symptoms of acute pancreatitis subsided, her anaemia, thrombocytopenia and acute kidney injury worsened...

BACKGROUND: Renin angiotensin antagonists (RAAs) may block protective vasopressor responses during surgery. Evidence linking RAAs with intraoperative hypotension and perioperative adverse events is conflicting. METHODS: Retrospective case-control study of 258 consecutive patients who underwent elective total knee or hip replacement between January 1(st) 2013 and August 31(st) 2016, and who were chronically prescribed a single blood pressure lowering agent up to the time of surgery...

A 64-year-old man visited our hospital with complaints of misty vision and ophthalmalgia. On admission, his blood pressure (BP) was high at 220/135 mmHg with no past history of hypertension, and he had choked discs. He was tentatively diagnosed as having idiopathic intracranial hypertension, and was later found to have atherosclerotic unilateral renovascular hypertension (RVH) based upon the extremely high plasma renin activity together with the radiological image tests. On day 3, combined antihypertensive therapies consisting of oral angiotensin II receptor blocker (ARB) and Ca channel blocker (CCB) along with intravenous CCB induced an abrupt BP lowering which led to deterioration of his renal function, progressing into acute kidney injury (AKI)...

Critically ill patients with acute kidney injury (AKI) are heterogeneous on pathophysiology and prognosis. The role of endothelial damage in the pathogenesis of refractory AKI has not been clarified. The aim was to determine if biomarkers of endothelial damage, independently of the inflammatory insult on the kidney, can predict recovery of acute kidney injury. METHODS: From the "Procalcitonin And Survival Study" multicenter intensive care unit cohort, followed for 28 days after admission, we included patients without chronic kidney disease, who survived >24 h after admission and with plasma samples at admission available for biomarker analysis...

BACKGROUND: Angiotensin converting enzyme inhibitors (ACEIs) and angiotensin II receptor blockers (ARBs) are considered to have similar renoprotective effects; so far there has been no consensus about their priorities. This study aimed to compare ACEIs and ARBs for major renal outcomes and survival in a 15-year cohort of adults with diabetes. METHODS: This study utilized Taiwan's medical and pharmacy claims data in the Longitudinal Cohort of Diabetes Patients. The primary outcome was long-term dialysis, and secondary outcomes were hospitalization for acute kidney injury, hospitalization for hyperkalemia, all-cause death, cardiovascular death, and non-cardiovascular death...

Epidemiological and experimental studies reveal that Western dietary patterns contribute to chronic kidney disease, whereas dietary restriction (DR) or dietary polyphenols such as green tea polyphenols (GTPs) can ameliorate the progression of kidney injury. This study aimed to investigate the renal protective effects of GTPs and explore the underlying mechanisms. Sixty Wistar rats were randomly divided into 6 groups: standard diet (STD), DR, high-fat diet (HFD), and three diets plus 200 mg/kg(bw)/day GTPs, respectively...

BACKGROUND: Nuclear factor erythroid 2-related factor 2 (NRF2) is a critical transcription factor for the antioxidative stress response and it activates a variety of cytoprotective genes related to redox and detoxification. NRF2 activity is regulated by the oxidative-stress sensor molecule Kelch-like ECH-associated protein 1 (KEAP1) that induces proteasomal degradation of NRF2 through ubiquitinating NRF2 under unstressed conditions. Because oxidative stress is a major pathogenic and aggravating factor for kidney diseases, the KEAP1-NRF2 system has been proposed to be a therapeutic target for renal protection...

Leptospirosis is frequently associated with acute kidney injury. Some survivors are known to progress to chronic kidney disease due to sustained tubulointerstitial inflammation. We present a case of severe leptospirosis with acute renal failure. Although antibiotic therapy resolved the infection, moderate renal dysfunction remained. A renal biopsy demonstrated marked inflammatory infiltration in the tubules and interstitium. Many of the inflammatory cells were CD68-positive monocytes/macrophages, predominantly M1 phenotype...

BACKGROUND: Acute kidney injury (AKI) is common in patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF); however, few studies concerning the risk factors and recovery patterns of renal function have been published. MATERIALS AND METHODS: A retrospective analysis of 150 patients with HBV-ACLF was performed. The occurrence, risk factors and functional recovery of AKI among patients with HBV-ACLF were investigated. RESULTS: A total of 90 patients (60%) with HBV-ACLF developed AKI...

RATIONALE AND OBJECTIVES: Sodium and proton magnetic resonance imaging ((23)Na/(1)H-MRI) have shown that muscle and skin can store Na(+) without water. In chronic renal failure and in heart failure, Na(+) mobilization occurs, but is variable depending on age, dialysis vintage, and other features. Na(+) storage depots have not been studied in patients with acute kidney injury (AKI). MATERIALS AND METHODS: We studied 7 patients with AKI (mean age: 51.7 years; range: 25-84) and 14 age-matched and gender-matched healthy controls...

Liver cirrhosis is the severe period of chronic liver diseases, especially decompensated liver cirrhosis and its complications, such as ascites, esophagogastric variceal bleeding, hepatic encephalopathy, acute kidney injury, and hepatocellular carcinoma, which greatly affect patients' quality of life and even threaten their lives. Early prevention and treatment of the causes of development and progression and pathogenic mechanism may slow down or reverse liver cirrhosis and its severe complications. Once the disease progresses to portal hypertension and related complications, it is very important to select preventive measures for acute exacerbation of different complications, as well as the methods and timing for treatment in acute stage, which may help to save patients' lives and improve their prognosis...
