The prevalence of kidney stones and cardiovascular diseases (CVDs) are increasing throughout the world. Both diseases are chronic and characterized by accumulation of oxidized proteins and lipids in the renal tissue and arterial wall, respectively. Emerging studies have revealed a positive association between nephrolithiasis and CVDs. Based on preclinical and clinical evidences, this review discusses: (i) stone forming risk factors, crystal nucleation, aggregation, injury-induced crystal retention, and stone formation, (ii) CVD risk factors such as dyslipidemia, perturbation of gut microbiome, obesity, free radical-induced lipoprotein oxidation, and retention in the arterial wall, subsequent foam cell formation, and atherosclerosis, (iii) mechanism by which stone forming risk factors such as oxalate, calcium, uric acid, and infection contribute toward CVDs, and (iv) how CVD risk factors, such as cholesterol, phospholipids, and uric acid, contribute to kidney stone formation are described...

It is well known that autophagy serves a crucial role in renal tubular epithelial cell (RTEC) injury in the pathogenesis of chronic kidney disease (CKD). The accumulation of advanced oxidation protein products (AOPPs) also participates in the progression of CKD. However, the effects of AOPPs on autophagy remain unknown. To clarify the underlying mechanism of RTEC injury in CKD, the effect of AOPPs on HK-2 cells, an RTEC cell line, was investigated. The results of the present study revealed that AOPP exposure downregulated the expression of B-cell lymphoma-2-interacting myosin-like coiled-coil protein 1, reduced the conversion of microtubule-associated proteins 1 light chain 3B (LC3)-I to LC3-II and the formation of autophagosomes, and lead to an accumulation of p62...

BACKGROUND Fibrosis is the common pathological feature in most kinds of chronic kidney disease (CKD). TGF-β/Smads signaling is the master pathway regulating kidney fibrosis pathogenesis, in which Smad3 acts as the integrator of various pro-fibrosis signals. In this study, we analyzed the role of SIS3, a specific inhibitor of Smad3, in mouse unilateral ureteral obstruction (UUO) kidneys. MATERIAL AND METHODS UUO mice were intraperitoneally injected with 0.2 mg/kg/day or 2 mg/kg/day of SIS3 or control saline for 7 days, followed by analysis of structure injury, fibrosis status, inflammation, apoptosis, and TGF-β/Smads signaling activity...

BACKGROUND: Renal disease is considered the main cause of natural mortality in dogs with canine leishmaniosis. The pathological mechanisms associated with kidney injury in canine leishmaniosis include immune complex glomerulonephritis, tubulointerstitial nephritis and occasionally renal amyloidosis. Proteinuria is a frequent finding in canine leishmaniosis and its quantification by the urine protein-creatinine ratio (UPC) is an important parameter in the staging of canine lesihmaniosis as presented by the LeishVet group...

Background/Aims: The true incidence of aristolochic acid nephropathy (AAN) is thought to be underestimated because numerous ingredients known or suspected to contain aristolochic acid (AA) are used in traditional medicine in Korea. Methods: We collected data on cases of AAN since 1996 via a database in Korea. We evaluated the year of AAN development, route to obtaining AA-containing herbal medicine, gender, reason for taking AA-containing herbal medicine, clinical manifestations, histological findings, phytochemical analysis, and prognosis of patients with AAN...

Recent evidence suggests that renal tubular injury plays a key role in deterioration of renal function in both chronic kidney disease (CKD) and acute kidney injury (AKI). Since commonly used biochemical indicators such as GFR, serum creatinine, blood urea nitrogen and creatinine clearance are inappropriate for detecting alteration in renal tubules, biomarkers reflecting renal tubular injury have been extensively explored. Our research group identified leucine rich α-2 glycoprotein (LRG) as a novel serum biomarker for various inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease...

Acute kidney injury induced by ischemia/reperfusion is an independent risk factor for chronic kidney disease. Macrophage recruitment plays an essential role during the injury and repair phases after an ischemic episode in the kidney. Here we show that the novel non-steroidal mineralocorticoid receptor antagonist finerenone or selective myeloid mineralocorticoid receptor ablation protects against subsequent chronic dysfunction and fibrosis induced by an episode of bilateral kidney ischemia/reperfusion in mice...

Acute kidney injury (AKI) has been associated with not only higher in-hospital mortality but also the subsequent development of chronic kidney disease (CKD). Recent evidence has suggested the involvement of mitochondrial dysfunction and impaired dynamics in the pathogenesis of AKI. Estrogen-related receptor α (ERRα) is an orphan nuclear receptor that acts as a transcription factor to regulate the transcription of genes required for mitochondrial biogenesis and oxidative phosphorylation. In the present study, we examined the effects of ERRα deficiency on the progression of AKI induced by cisplatin...

OBJECTIVE: To evaluate the association of clinical factors on outcomes in SCI patients undergoing ureteroscopy. Immobility, recurrent urinary tract infection, and lower urinary tract dysfunction contribute to renal stone formation in spinal cord injury (SCI) patients. Ureteroscopy is a commonly utilized treatment modality, however, surgical complication rates and outcomes have been poorly defined. Evidence guiding safe and effective treatment of stones in this cohort remains scarce. METHODS: Records were retrospectively reviewed for SCI patients who underwent ureteroscopy for kidney stones from 1996-2014 at a single institution...

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)...

Oxidative stress resulting from excessive production of reactive oxygen species (ROS) or impaired antioxidant defenses is closely related to the development of diabetic vascular complications, including nephropathy and atherosclerosis. Chronic activation of Janus kinase/Signal transducer and activator of transcription (JAK/STAT) signaling pathway contributes to diabetic complications by inducing expression of genes involved in cell proliferation, fibrosis, inflammation, and oxidative stress. Suppressors of cytokine signaling (SOCS) family of endogenous JAK/STAT regulators is an attractive target for therapeutic intervention...

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...
