The aim of the present study was to analyze the risk factors for new-onset chronic kidney disease (CKD) in patients who have received a liver transplant. A total of 190 patients who underwent liver transplantation between March 2001 and January 2015 were followed up, and analyzed retrospectively. Sex, age, primary disease, preoperative laboratory findings (hemoglobin, albumin, creatinine and glomerular filtration rate), surgical approach, blood loss during the surgery and transfusion volume, postoperative complications, and the average levels of calcineurin inhibitors (CNIs) (from liver transplantation to the onset of CKD) were analyzed...

Acute kidney injury is a sudden decrease in kidney function with or without kidney damage, occurring over a few hours or days. Diabetes, hypertension, and advanced age are primary risk factors for acute kidney injury. It is increasingly recognized as an in-hospital complication of sepsis, heart conditions, and surgery (1,2). Its most severe stage requires treatment with dialysis. Acute kidney injury is also associated with higher likelihood of long-term care, incidence of chronic kidney disease and hospital mortality, and health care costs (1,2)...

Blood oxygen level-dependent magnetic resonance imaging (BOLD MRI) has recently been utilized as a noninvasive tool for evaluating renal oxygenation. Several methods have been proposed for analyzing BOLD images. Regional ROI selection is the earliest and most widely used method for BOLD analysis. In the last 20 years, many investigators have used this method to evaluate cortical and medullary oxygenation in patients with ischemic nephropathy, hypertensive nephropathy, diabetic nephropathy, chronic kidney disease (CKD), acute kidney injury and renal allograft rejection...

BACKGROUND: Liver transplantation (LT) is a successful treatment for both acute liver failure and end-stage liver disease. The number of women of reproductive age undergoing LT is increasing. Pregnancy outcomes are favourable but there is still a lack of prognostic markers. We aimed to identify factors predictive of adverse pregnancy outcomes in LT recipients. METHODS: An analysis of all pregnancies occurring in LT recipients from 1989-2016 at King's College Hospital was performed...

Transcatheter aortic valve implantation (TAVI) is associated with acute kidney injury (AKI), but can also improve the kidney function (IKF). We assessed the effects of kidney function changes in relation to baseline kidney function on 2-year clinical outcomes after TAVI. In total, 639 consecutive patients with aortic stenosis who underwent TAVI were stratified into 3 groups according to the ratio of serum creatinine post- to pre-TAVI: IKF (≤0.80; n = 95 [15%]), stable kidney function (0.80 to 1.5; n = 477 [75%]), and AKI (≥1...

In Sri Lanka, an endemic of chronic kidney disease of unknown origin (CKDu) is affecting rural communities. The endemic has similarities with Mesoamerican Nephropathy (MeN) in Central America, however it has not yet been clarified if the endemics are related diagnostic entities. We designed this study of kidney biopsies from patients with CKDu in Sri Lanka to compare with MeN morphology. Eleven patients with CKDu were recruited at the General Hospital, Polonnaruwa, using similar inclusion and exclusion criteria as our previous MeN studies...

BACKGROUND: We previously reported that children undergoing cardiac surgery are at high risk for long-term chronic kidney disease (CKD) and hypertension, although postoperative acute kidney injury (AKI) is not a risk factor for worse long-term kidney outcomes. We report here our evaluation of renal injury biomarkers 5 years after cardiac surgery to determine whether they are associated with postoperative AKI or long-term CKD and hypertension. METHODS: Children aged 1 month to 18 years old undergoing cardiopulmonary bypass were recruited to this prospective cohort study...

INTRODUCTION: Non-human leukocyte antigen antibodies are an independent risk factor for acute rejection in kidney transplant recipients. Among them, angiotensin II receptor type 1 (ART1) antibodies can induce various effects, but their clinical importance in kidney transplant recipients has not been properly explained. This study aimed to evaluate the effect of ART1 antibodies on allograft function and hypertension in stable kidney transplant recipients. MATERIALS AND METHODS: Eighty-one kidney recipients from non- human leukocyte antigen antibodies-matched donors with stable allograft function were examined for estimated glomerular filtration rate (Chronic Kidney Disease-Epidemiology Collaboration formula) and ART1 antibodies (measured using an enzyme-linked immunosorbent assay method)...

INTRODUCTION AND OBJECTIVES: Chronic kidney disease is related to poor outcomes in patients with heart failure (HF). Few studies have assessed whether renal function influences one-year mortality risk in patients admitted for the first time for acute HF. METHODS: We reviewed the medical records of all patients aged >50 years admitted within a two-year period for a first episode of decompensated HF. The sample was divided according to the patients' estimated glomerular filtration rate (eGFR) on admission into three groups (eGFR >60, 30-60 and <30 ml/min/1...

Urate is a cause of gout, kidney stones, and acute kidney injury from tumor lysis syndrome, but its relationship to kidney disease, cardiovascular disease, and diabetes remains controversial. A scientific workshop organized by the National Kidney Foundation was held in September 2016 to review current evidence. Cell culture studies and animal models suggest that elevated serum urate concentrations can contribute to kidney disease, hypertension, and metabolic syndrome. Epidemiologic evidence also supports elevated serum urate concentrations as a risk factor for the development of kidney disease, hypertension, and diabetes, but differences in methodologies and inpacts on serum urate concentrations by even subtle changes in kidney function render conclusions uncertain...

The incidence of acute kidney injury (AKI) rises with age and is associated with multiple risk factors. Here, we compared the risk factors for AKI between younger and older incident diabetic patients to examine the trends in risk alteration for individual factors across different age groups. Between 2007 and 2013, we selected all incident type 2 diabetic adults from the Taiwan National Health Insurance registry, stratified based on age: young (< 65 years), old (≥ 65 but < 75 years), and older-old (≥ 75 years)...

OBJECTIVE: Postoperative acute kidney injury (AKI) is frequent after major vascular surgery and is associated with significant morbidity and mortality. It remains unclear whether the administration of combined oral antihypertensive medications on the day of surgery can increase the risk of postoperative AKI. METHODS: We performed a retrospective cohort study of hypertensive patients undergoing elective major vascular surgery to determine the association between the number of antihypertensive medications continued on the morning of surgery and AKI at 48 hours postoperatively...

Renal involvement in some forms of acute or chronic diseases, such as heart failure or sepsis, presents with a complex pathophysiological basis that is not always clearly distinguishable. In these clinical settings, kidney failure is traditionally and almost exclusively attributed to renal hypoperfusion and it is commonly accepted that causal elements are pre-renal, such as a reduction in the ejection fraction or absolute or relative hypovolemia acting directly on oxygen transport mechanisms and renal autoregulation systems, causing a reduction of glomerular filtration rate...

Renal ischemia reperfusion injury (IRI) is a severe complication after major surgery and a risk factor for increased morbidity and mortality. We investigated potential mechanisms, which contribute to IRI induced progression to chronic kidney disease. Acute kidney injury was induced by unilateral IRI for 35 min in CD1 and C57BL/6 (B6) mice. Unilateral IRI was chosen in order to overcome mortality. Renal morphology, NGAL up-regulation, and neutrophil infiltration as well as peritubular capillary density was studied by immunohistochemistry...
