BACKGROUND Chronic kidney disease (CKD) is a disorder with high morbidity and mortality worldwide whose complications generate multiple costs. In Ecuador, only a few healthcare institutions have implemented management protocols aimed to reduce costs and to improve the quality of life of patients. The aim of this study is to evaluate the short-term (1-year) and long-term (5-year) costs and savin...

The aim of this study was to assess any potential additive effects of a treatment combining aliskiren with paricalcitol on reducing renal fibrosis. C57BL/6J mice were treated individually with aliskiren and/or paricalcitol until 7 days after initiation of unilateral ureteral obstruction (UUO).In obstructed kidneys of UUO mice, monotherapy with aliskiren or paricalcitol significantly attenuated ...

Abstract Background The effects of vitamin D receptor (VDR) agonist paricalcitol on the podocyte injury induced by high glucose (HG) were investigated in conditioned immortalized mouse podocytes (MPC-5). Methods (1) Grouped according to different concentrations: normal group (NG): 5.6 mmol/L glucose; HG stimulation group: 25 (25HG); osmotic control (NG+M): + 19.4 D-mannitol. expression levels V...

PURPOSE We assessed the safety and efficacy of the vitamin D analogue, 19-nor-1alpha-25-dihydroxyvitamin D2 (paricalcitol), in patients with androgen-independent prostate cancer. EXPERIMENTAL DESIGN Patients received paricalcitol i.v. three times per week on an escalating dose of 5 to 25 microg (3-15 microg/m2). The primary end point was prostate-specific antigen (PSA) response. Secondary end...

1, 25-Dihydroxycholechalciferol (calcitriol) and 19-nor-1, 25-dihydroxyvitamin D2 (paricalcitol) are vitamin D receptor (VDR) agonists. Previous data suggest VDR agonists may actually increase renin-angiotensin activity, and this has always been assumed to be mediated by hypercalcemia. We hypothesized that calcitriol and paricalcitol would increase plasma renin activity (PRA) independently of p...

BACKGROUND Chronic kidney disease (CKD) is associated with elevations in serum phosphate, calcium-phosphorus product and bone-specific alkaline phosphatase (BAP), with attendant risks of cardiovascular and bone disorders. Active vitamin D can suppress parathyroid hormone (PTH), but may raise serum calcium and phosphate concentrations. Paricalcitol, a selective vitamin D activator, suppressed PT...

4-Hydroxy-2-hexenal (HHE), the aldehyde product of lipid peroxidation, may be responsible for the pathogenesis of progressive renal disease. Recently, paricalcitol (19-nor-1,25-dihydroxyvitamin D2) was shown to be renoprotective through its anti-inflammatory and antifibrotic effects in various experimental nephropathy models. In this study, we investigated the effects of paricalcitol on inflamm...

INTRODUCTION Recent studies have revealed that vitamin D and its synthetic analogues have a protective effect on experimental ischemia/reperfusion (I/R) models in several organs, but little is known about its effect on the liver. The aim of this study was to evaluate the beneficial effects of vitamin D in a model of liver I/R in rats, focusing on Toll-like receptor (TLR) 4 signaling, which has ...

Severe secondary hyperparathyroidism is a complication of chronic kidney disease. Paricalcitol is a vitamin D receptor activator with efficacy in the treatment of hyperparathyroidism that also has the minor side effects of hypercalcemia and hyperphosphatemia. As a pleiotropic effect, paricalcitol reduces proteinuria in patients with chronic kidney disease stages 2-4. Oral paricalcitol offers an...
