BACKGROUND: Mitochondrial dysfunction plays an important role in the pathogenesis and progression of chronic kidney disease (CKD). We study the relation between urinary mitochondrial DNA (mtDNA) levels and renal dysfunction in non-diabetic CKD. METHODS: We recruited 32 CKD patients (20 had hypertensive nephrosclerosis, 12 had IgA nephropathy). Urinary supernatant mtDNA level was measured and compared to baseline clinical and pathological parameters. The patients were followed 57...

Diabetic kidney disease is the major cause of end-stage kidney disease in developed countries. However, the onset of kidney disorder and the progression pattern of kidney dysfunction and proteinuria greatly vary cases by cases. Therefore, risk classification with clinical data and pathological findings is important. Recent clinico-pathological study with kidney biopsy samples from diabetic patients revealed that pathological changes of diabetic nephropathy are characteristic and have special impacts on prognosis in each clinical stage...

An 8 yr, intact male red-rumped agouti ( Dasyprocta leporina) was evaluated for weight loss. Examination revealed poor body condition, hypercalcemia, elevated serum 25-hydroxyvitamin D, metastatic calcification of soft tissues, and hyperechoic kidneys. The diet, formulated for laboratory rodents, contained elevated levels of vitamin D3 . Histopathology from a female conspecific that died 5 mo prior identified dystrophic mineralization and nephrosclerosis, suggestive of a vitamin D3 toxicity. The male agouti responded well to a dietary reduction in vitamin D3 and calcium...

A vesicocutaneous fistula (VCF) is a tract that is formed abnormally between the bladder and the external surface of the body. VCF results in a great deal of inconvenience, discomfort, and physical disability for the affected patient. This condition can be caused by extensive trauma with pelvic bone fracture, radical pelvic surgery, irradiation of pelvic malignancies, hip arthroplasty, a large bladder calculus, and various other pathologies. The management of VCF should be approached on a case-by-case basis because of the complexity of the disease...

C1q glomerulopathy is a rare variety of chronic glomerulonephritis manifested as C1q deposition revealed by immunofluorescence microscopy. The pathogenesis and etiology of the disease have not been studied. The paper deals with the results of clinical, morphological, immunofluorescence, and electron microscopic examinations in 13 patients with C1q glomerulopathy. Light microscopy more commonly revealed membranous nephropathy, mesangioproliferative glomerulonephritis, and nephrosclerosis. Immunofluorescence microscopy detected a C1q fraction in association with other deposits, more frequently IgM and IgG ones...

PURPOSE: To investigate the association of renal elasticity to microscopic findings of nephron hypertrophy and nephrosclerosis. METHODS: Patients who underwent renal biopsy were enrolled. Renal elasticity was measured by acoustic radiation force impulse, and nephron size (glomerular volume, non-sclerotic glomerular density, and mean profile tubular area) and nephrosclerosis (globally sclerotic glomeruli and interstitial fibrosis) were estimated. Nephron hypertrophy was indicated by larger glomerular volume, larger tubular area, and lower non-sclerotic glomerular density...

BACKGROUND: Although lower estimated glomerular filtration rate (eGFR) and higher proteinuria are high risks for mortality and kidney outcomes, the prognosis of chronic kidney disease (CKD) in patients with normal-range proteinuria remains unclear. METHODS: In this prospective cohort study, 1138 newly visiting stage G2-G5 CKD patients were stratified into normal-range and abnormal-range proteinuria groups. Study endpoints were CKD progression (>50% eGFR loss or initiation of dialysis), cardiovascular events, and all-cause death...

Delayed bowel erosion by peritoneal dialysis catheter is rare with fewer than thirty cases having been reported in the literature. This complication is usually encountered when the catheter is kept dormant. Two cases have also been reported with catheters in active use. The risk factors for bowel erosion include immunosuppression, diverticulosis, and amyloidosis. An 80-year-old male with chronic kidney disease Stage 5 due to hypertensive nephrosclerosis underwent chronic ambulatory peritoneal dialysis catheter insertion...

BACKGROUND: Hypertensive nephropathy, a leading cause of declining kidney function, is a multifactorial process not well understood. In order to elucidate biological processes and identify novel macromolecular components crucially involved in the process of kidney damage, the application of system biology approaches, like proteomics, is required. METHODS: Proteomic studies were performed using the renal parenchyma of spontaneously hypertensive rats (SHR) and their normotensive Wistar Kyoto controls...

BACKGROUND: Nephrosclerosis is an increasingly reason for dialysis in Japan. However, kidney biopsy specimens for hypertensive nephrosclerosis are very limited; thus, the pathologic evaluation of hypertensive nephrosclerosis currently remains unclear. METHODS: Clinical and pathologic data of a total of 184 biopsy-confirmed hypertensive nephrosclerosis patients were collected from 13 centers throughout Japan. Seven pathological findings were assessed in this study...

PURPOSE OF REVIEW: Bile acids act as activating signals of endogenous renal receptors: the nuclear receptor farnesoid X receptor (FXR) and the membrane-bound G protein-coupled bile acid receptor 1 (GPBAR1, also known as TGR5). In recent years, bile acids have emerged as important for renal pathophysiology by activating FXR and TGR5 and transcription factors relevant for lipid, cholesterol and carbohydrate metabolism, as well as genes involved in inflammation and renal fibrosis. RECENT FINDINGS: Activation of bile acid receptors has a promising therapeutic potential in prevention of diabetic nephropathy and obesity-induced renal damage, as well as in nephrosclerosis...

An 83-year-old Japanese man had a history of chronic heart failure due to bradycardia-tachycardia syndrome. He was admitted to our hospital because of macrohematuria and acute kidney injury (AKI), which were detected by an urologist at an outpatient visit. He had a history of recurrent macrohematuria and transurethral resection of bladder tumors twice in the preceding 2 years. He had been on warfarin for 12 years, with a stable international normalized ratio (INR) that was usually less than 2.1. Urinalysis revealed numerous red blood cells (RBCs) and mild proteinuria without RBC casts...

We report the case of a patient with long-term history of hypertension, presenting with transient neurological disorders and severe graft failure several years after kidney transplantation. Cause of end-stage renal disease was hypertensive nephrosclerosis. Chronic hemodialysis lasted for 1 year. After transplantation and throughout follow-up, serum creatinine ranged from 200 to 230 μmol/L and maintenance immunosuppression included sirolimus and low-dose steroids. Six years after transplantation, the patient presented with right hip pain radiating to the lower back, transient aphasia, confusion, and hemiparesis...

REVIEW
Musab S Hommos, Richard J Glassock, Andrew D Rule
Aging is associated with significant changes in structure and function of the kidney, even in the absence of age-related comorbidities. On the macrostructural level, kidney cortical volume decreases, surface roughness increases, and the number and size of simple renal cysts increase with age. On the microstructural level, the histologic signs of nephrosclerosis (arteriosclerosis/arteriolosclerosis, global glomerulosclerosis, interstitial fibrosis, and tubular atrophy) all increase with age. The decline of nephron number is accompanied by a comparable reduction in measured whole-kidney GFR...

Background Patients with chronic kidney disease (CKD) often have the complication of anaemia. Usage of an erythropoietin-stimulating agent accelerates iron deficiency because it promotes iron utilization. Recently, iron administration was reported to be effective for patients with cardiac failure. We examined the association between ferrokinetics and cardiac function in patients with CKD. Methods In this cross-sectional study, we examined 558 patients (424 men and 134 women; mean age, 68.9 ± 13.1 years) with CKD who were admitted to our hospital...
