Divergent effects of AKI to CKD models on inflammation and fibrosis.

This study provides support for subtyping AKI by etiology in human studies, aiding in the elucidation of injury-specific pathophysiologic mechanisms of the AKI to CKD transition. PMID: 29897282 [PubMed - as supplied by publisher]

Purpose of review Despite improvement in short-term renal allograft survival in recent years, renal transplant recipients (RTR) have poorer long-term allograft outcomes. Allograft function slowly declines with periods of stable function similar to natural progression of chronic kidney disease in nontransplant population. Nearly all RTR transitions to failing renal allograft (FRG) period and require transition to dialysis. Conservative chronic kidney disease management before transition to end-stage renal disease is an increasingly important topic; however, there is limited data in RTR regarding how to delay dialysis init...

Chronic kidney disease (CKD) is prevalent worldwide and is associated with significant co-morbidities including cardiovascular disease (CVD). Traditionally, the subtotal nephrectomy (remnant kidney) experimental model has been performed in rats to model progressive renal disease. The model experimentally mimics CKD by reducing nephron number, resulting in renal insufficiency. Presently, there is a lack of translation of pre-clinical findings into successful clinical results. The pre-clinical nephrology field would benefit from reproducible progressive renal disease models in mice in order to avail of more widely available ...

Abstract Animal models of chronic kidney failure (CKF) have been developed for the pharmacodynamic evaluation of various phosphate binders that are used clinically to treat hyperphosphatemia in patients with chronic kidney disease. However, these models represent different disease states and severities, depending on the experimental conditions and are not clearly defined for pharmacological evaluation. In addition, experimental models have not yet been established for artificial dialysis. The purpose of this study was to confirm the utility of the various rat models of CKF and the mini-pig model of hemodialysis as...

This study investigated the therapeutic efficacy of resveratrol (RSV), a polyphenolic compound, on left ventricular remodeling in subtotal nephrectomy rats and sought to uncover the underlying molecular mechanisms. Subtotal nephrectomy c aused renal dysfunction, such as gradual increases in serum creatinine and blood urea nitrogen, glomerular sclerosis, and tubulointerstitial fibrosis. In addition, subtotal nephrectomy also resulted in significant increases in myocyte cross‐sectional area, interstitial and perivascular fibrosis, a nd left ventricular dilatation. All these detrimental effects were alleviated in the presen...

This study aimed to evaluate the likelihood of progression to chronic kidney disease (CKD) in a cohort of geriatric Asian patients aged over 65 years who underwent either partial nephrectomy (PN) or radical nephrectomy (RN) for localised pT1 kidney tumours. METHODS: Geriatric patients aged over 65 years who underwent PN or RN for localised kidney mass

Publication date: Available online 15 October 2019Source: Urology Case ReportsAuthor(s): Akito Ito, Mizuki Hisano, Makoto Takahashi, Naoki Komine, Takaya Abe, Wataru ObaraAbstractA 73-year-old-male patient with hypertension and grade 3B chronic kidney disease underwent radical nephrectomy in the year 2000. As the renal function gradually worsened, the patient was started on hemodialysis in 2003. Eleven years after nephrectomy, the metastases were pointed out. The patient received sunitinib as first-line therapy. Thereafter, as the metastatic lesions became larger, we initiated nivolumab therapy (3 mg/m2 every 2 weeks). Aft...

Abstract AIM: To provide a comprehensive analysis of the outcomes of partial nephrectomy (PN) and radical nephrectomy (RN) for renal cell carcinoma (RCC) in older patients. METHODS: The RESURGE project is a multi-institutional dataset including 24 institutions worldwide collecting data of patients older than 75 years old who underwent RN or PN. RESULTS: Among three already published studies, RN patients were older (p

ConclusionA diuretic added to the combined RAS and ETA blockade has late renoprotective effects in CKD induced by partial nephrectomy in Ren-2 transgenic rats. The diuretic improved: renal function (evaluated as proteinuria and creatinine clearance), renal morphology (kidney mass, glomerular volume), and histological markers of kidney damage (glomerulosclerosis index, tubulointerstitial injury).

CK, Zatz R Abstract Hypoxia is thought to influence the pathogenesis of chronic kidney disease (CKD), but direct evidence that prolonged exposure to tissue hypoxia initiates or aggravates CKD is lacking. We tested this hypothesis by chronically exposing normal rats and rats with 5/6 nephrectomy (Nx) to hypoxia. In addition, we investigated whether such effect of hypoxia would involve activation of innate immunity. Adult male Munich-Wistar rats underwent Nx (n=54) or sham surgery (S, n=52). Twenty six sham (S+Nor) and 26 Nx (Nx+Nor) rats remained in normoxia, while 26 sham rats (S+Hyp) and 28 Nx rats (Nx+Hyp) were ...
