Diabetes mellitus is an endocrine disease of multiple aetiologies in insulin secretion. A deficiency in insulin results in hyperglycemia with metabolic disturbances of biomolecules. Moringa oleifera (MO) is endemic in the tropics with a variety of ethnomedicinal importance. The leaf of this plant has been reported to possess antioxidant and medicinal properties that may be helpful in the treatment and management of diabetes and its associated complications. Diabetes was induced intraperitoneally in rats by a single dose of streptozotocin (55 mg/kg) and treated with methanolic extract of Moringa oleifera (250 mg/kg b...

Acute rejection is one of the major immunological determinants of kidney graft function and survival. Early biomarkers to predict rejection are lacking. Emerging evidence reveals a crucial role for the monocyte-macrophage lineage cells in the pathogenesis of rejection. We hypothesized that higher pre-transplant numbers of proinflammatory CD16+ monocytes can predict rejection. The study cohort consisted of 104 kidney transplant recipients (58 no-rejections and 46 biopsy-proven rejections), and 33 healthy individuals...

PURPOSE: D-dopachrome tautomerase (MIF-2 or DDT) is a member of the macrophage migration inhibitory factor (MIF) superfamily and a close structural homolog to MIF. Circulating MIF-2 has been described to be elevated in patients suffering from sepsis, severe burn injury and after surgery. We sought to evaluate the prognostic value of MIF-2 in critically ill patients. METHODS: A total of 72 patients were studied upon admission to the medical intensive care unit (ICU)...

Urinary extracellular vesicles (UEVs) appear an ideal source of biomarkers for kidney and urogenital diseases. The majority of protocols designed for their isolation are based on differential centrifugation steps. However, little is still known of the type and amount of vesicles left in the supernatant. Here we used an isolation protocol for UEVs which uses hydrostatic filtration dialysis as first pre-enrichment step, followed by differential centrifugation. Transmission electron microscopy (TEM), mass spectrometry (MS), western blot, ELISA assays and tuneable resistive pulse sensing (TRPS) were used to characterise and quantify UEVs in the ultracentrifugation supernatant...

The current view of diabetic kidney disease, based on meticulously acquired ultrastructural morphometry and the utility of measuring plasma creatinine and urinary albumin, has been almost entirely focused on the glomerulus. While clearly of great importance, changes in the glomerulus are not the major determinant of renal prognosis in diabetes and may not be the primary event in the development of diabetic kidney disease either. Indeed, advances in biomarker discovery and a greater appreciation of tubulointerstitial histopathology and the role of tubular hypoxia in the pathogenesis of chronic kidney disease have given us pause to reconsider the current "glomerulocentric" paradigm and focus attention on the proximal tubule that by virtue of the high energy requirements and reliance on aerobic metabolism render it particularly susceptible to the derangements of the diabetic state...

BACKGROUND & AIM: Activated leukocyte cell adhesion molecule (ALCAM/CD166) functions analogue to the receptor of advanced glycation end products, which has been implicated in the development of diabetic nephropathy (DN). We investigated the expression of ALCAM and its ligand S100B in patients with DN. METHODS: A total of 34 non-diabetic patients, 29 patients with type 2 diabetes and normal albuminuria and 107 patients with type 2 diabetes complicated with DN were assessed for serum concentration of soluble ALCAM (sALCAM) by ELISA...

Antisense oligonucleotide (AON) therapeutics offer new avenues to pursue clinically relevant targets inaccessible with other technologies. Advances in improving AON affinity and stability by incorporation of high affinity nucleotides, such as locked nucleic acids (LNA), have sometimes been stifled by safety liabilities related to their accumulation in the kidney tubule. In an attempt to predict and understand the mechanisms of LNA-AON-induced renal tubular toxicity, we established human cell models that recapitulate in vivo behavior of pre-clinically and clinically unfavorable LNA-AON drug candidates...

Mortality among the patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) remains high because of the very high incidence of cardiovascular disease (CVD) such as coronary artery disease, cardiac hypertrophy, and heart failure. Identifying CVD in patients with CKD/ESRD remains a significant hurdle and the early diagnosis and therapy for CVD is crucial in these patients. Therefore, it is necessary for the better management to identify and utilize cardiovascular (CV) biomarkers in profiling CVD risk and enabling stratification of early mortality...

PURPOSE OF REVIEW: Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disorder characterized by the formation of kidney cysts and kidney enlargement, which progresses to kidney failure by the fifth to seventh decade of life in a majority of patients. Disease progression is evaluated primarily through serum creatinine and estimated glomerular filtration rate (eGFR) measurements; however, it is known that serum creatinine and eGFR values typically do not change until the fourth or fifth decade of life...

Amphotericin B (AmpB) nephrotoxicity was used to assess the utility of drug‑induced kidney injury (DIKI) biomarkers in an exploratory study in male cynomolgus monkeys. All animals had quantifiable levels of AmpB in plasma on days 1 and 4. There were no clinical signs of AmpB‑induced toxicity in this study. The gold standard method used to confirm AmpB‑induced DIKI was anatomic pathology which revealed microscopic lesions with varying grades of severity. Immunolocalization of alpha‑1 microglobulin (α‑1M), kidney injury molecule 1 (KIM‑1), osteopontin (OPN) and neutrophil gelatinase‑associated lipocalin (NGAL) proteins was evaluated in formalin‑fixed, paraffin‑embedded monkey kidney tissue sections...

Contrast-induced nephropathy (CIN) is the third leading cause of hospital-acquired acute kidney injury (AKI). Emerging evidence has revealed that soluble klotho (sklotho) could be a novel biomarker for early AKI diagnosis. The aims of this study were to assess the predictive role of sklotho for CIN and to develop a prediction nomogram in patients undergoing percutaneous coronary intervention (PCI). This study is registered on Clinicaltrials.gov (NCT 02650336).Patients aged 18 years or older undergoing planned PCI were prospectively recruited between May 2014 and July 2015...

BACKGROUND: Patients with chronic kidney disease (CKD) due to glomerulonephritis (GN) are thought to be at high risk for cardiovascular disease (CVD). However, no study has examined whether GN directly contributes to CV risk beyond the effects conferred by pre-existing traditional risk factors and level of renal function. METHODS: Matched cohort study using the previously described prospective CanPREDDICT study cohort. 2187 patients with CKD (eGFR 15-45 ml/min/m(2)) from 25 Canadian centres were divided into GN vs non-GN cause of CKD...

RATIONALE: Sepsis-induced acute kidney injury (AKI) is a common condition with high morbidity and mortality. Neutrophil-derived heparin-binding protein (HBP) induces vascular leakage and is a promising biomarker of sepsis-induced organ dysfunction. It remains unknown if HBP is prognostic of AKI in septic shock and if HBP could play a role in the pathophysiology of sepsis-induced AKI. OBJECTIVES: To determine the association of plasma HBP levels with development of AKI, investigate the role of HBP in the pathophysiology of sepsis-induced AKI, and test the effect of blocking HBP using heparin derivatives...

Clinical proteomics has led to the identification of a substantial number of disease-associated peptides and protein fragments in several conditions such as cancer, kidney, or cardiovascular diseases. In silico prediction tools that can facilitate linking of identified peptide biomarkers to predicted protease activity might therefore significantly contribute to the understanding of pathophysiological mechanisms of these diseases. Proteasix is an open-source, peptide-centric tool that can be used to predict in silico the proteases involved in naturally occurring peptide generation...

The ATP monitoring assay is a useful biomarker for risk monitoring to detect infection and rejection episodes in transplant recipients. Hemodialysis patients have a higher rate of infectious mortality. Infections in hemodialysis patients are mainly caused by venous catheters, uremia, malnutrition and inflammation. However, the risk of infection episodes has not been evaluated using a lymphocyte ATP monitoring assay in hemodialysis and chronic kidney disease (CKD) patients. We measured the ATP amounts in the peripheral CD4+ cells of CKD (N = 85) and dialysis patients (N = 17) using an "Immuknow" assay kit...

BACKGROUND: A high incidence of unexplained positive urine reagent test strip reactions was observed in healthy, untreated laboratory-housed nonhuman primates, Beagle dogs, and Sprague-Dawley rats. Exposure of urine to cage pan contaminants was the suspected cause of the positive reactions. OBJECTIVES: The objective of this study was to identify cage pan contaminants which could cause positive reagent test strip reactions. METHODS: Contaminated urine was simulated by exposing water samples to cage pan contaminants, including cleaning solutions, feces from nonhuman primates, Beagle dogs, and Sprague-Dawley rats, certified laboratory animal diets, and dietary enrichments (vegetables, fruits, and food treats)...

Diabetic Nephropathy (DN) is the leading cause of end-stage renal disease. Preclinical and experimental studies show that PDE5 inhibitors (PDE5is) exert protective effects in DN improving perivascular inflammation. Using a mouse model of diabetic kidney injury we investigated the protective proprieties of PDE5is on renal hemodynamics and the molecular mechanisms involved. PDE5i treatment prevented the development of DN-related hypertension (P < 0.001), the increase of urine albumin creatinine ratio (P < 0...

Patients affected by Chronic Kidney Disease and Mineral Bone Disorder (CKD-MBD) have a high risk of cardiovascular (CV) mortality that is poorly explained by traditional risk factors. The newest medical treatments for CKD-MBD have been associated with encouraging, but still inconsistent, improvement in CV disease complications and patient survival. A better understanding of the biomarkers and mechanisms of left ventricular hypertrophy (LVH), atherosclerosis, and vascular calcification (VC) may help with diagnosis and treatment of the organ damage that occurs secondary to CKD-MBD, thus improving survival...
