Hyperphosphatemia and vascular calcification are frequent complications of chronic renal failure and bone morphogenetic protein 7 (BMP7) has been shown to protect against development of vascular calcification in uremia. The present investigation examined the potential reversibility of established uremic vascular calcification by treatment of uremic rats with BMP7. A control model of isogenic tr...

BACKGROUND Uremia is proposed to increase sympathetic nerve activity (SNA) in hemodialysis patients. The aims of the present study were to determine whether reversal of uremia by successful kidney transplantation (RTX) eliminates the increased SNA and whether signals arising in the diseased kidneys contribute to the increased SNA in renal failure. METHODS AND RESULTS We compared muscle sympat...

PURPOSE Cardiac bioenergetics are known to be abnormal in experimental uremia as exemplified by a reduced phosphocreatine (PCr)/adenosine triphosphate (ATP) ratio. However, the progression of these bioenergetic changes during the development of uremia still requires further study and was therefore investigated at baseline, 4 weeks and 8 weeks after partial nephrectomy (PNx). METHODS A two-sta...

BACKGROUND Endothelial cells (ECs) embedded in 3D matrices [matrix-embedded endothelial cells (MEECs)] of denatured collagen implanted around vascular access anastomoses preserve luminal patency. MEEC implant efficacy depends on embedded EC health. As the uremic milieu inhibits proliferation and induces apoptosis of ECs, we examined whether uremia might impact MEECs. METHODS ECs grown on 2D g...

Klotho plays an important role in the pathogenesis of cardiovascular disease in chronic kidney disease (CKD). Klotho is highly expressed in the kidney and parathyroid glands, but its presence in the vasculature is debated. Renal Klotho is decreased in CKD, but the effect of uremia on Klotho in other tissues is not defined. The effect of vitamin D receptor activator therapy in CKD on the express...

OBJECTIVES What is the prognostic significance of achieving a systolic blood pressure of <140 mmHg? SETTING Diabetic renal policlinic, university hospital of Lund, Sweden. SUBJECTS 118 type 2 diabetic patients with micro-macroalbuminuria were followed for four years (range 1-8 years). METHOD AND MAIN OUTCOME MEASURES: The prognostic significance of office, day- and nighttime measurements of...

Data on survival after transfer from peritoneal dialysis (PD) to hemodialysis (HD) is conflicting. We reviewed two decades of outcomes in a PD program to examine short-term survival after transfer from PD to HD. Of 379 patients on PD, 33% transferred to HD. The reasons for transfer were PD-related infections (340%), uremia or failure to thrive (26%), PD catheter problems or loss of mechanical s...

Consciousness disturbance is a common problem in patients undergoing dialysis. For uremia patients who present with consciousness disturbance and specific findings focus on the bilateral ganglions on an imaging study are rare. A 52-year-old female was admitted because of general weakness and drowsy consciousness for one day. Her past history included end-stage renal disease; she had been on reg...
