Filter by:Bone disorder is a significant problem in chronic kidney disease (CKD), becoming almost universal in stage 5 CKD patients. Besides the healthcare costs, bone disorder is associated with life-threatening complications, including fractures and cardiovascular (CV) events. Kidney transplantation provides circa 68% decrease in mortality and improves co-morbidity. Still, bone disease persists after transplantation. The investigators hypothesize that bone-derived hormones can induce CV events in kidney transplanted patients. Therefore, early evaluation of the bone health is recommended, and prevention of its complications is required. Bone biopsy, an invasive and expensive method, is the gold standard for bone disorders diagnosis. Therefore, non-invasive predictors for bone disease are necessary. Classical biochemical markers of bone formation and resorption have shown a low sensitivity and low specificity. New markers, as fibroblast growth factor 23 (FGF23), and its cofactor klotho, and sclerostin are promising new markers for predicting CKD-associated bone and CV disease after transplantation. This study assesses the phenotype of bone disease after transplantation (given by bone histology) and its correlation with serum FGF23, klotho and sclerostin, in order to evaluate its performance predicting CKD-associated bone and CV disease.
Most chronic kidney diseases have a progressive evolution characterized by the gradual loss of glomerular filtration rate (GFR), electrolytic imbalance, reduced erythropoietin synthesis and activation of vitamin D. On many occasions, the progressive deterioration of renal function occurs, even when the etiologic factors responsible for the kidney disease are treated and/or eliminated as a result of an auto-sustained mechanism of inflammation and fibrosis. Moreover, chronic nephropathies are often associated with high blood pressure and increased urine protein excretion, being both risk factors of progression toward kidney failure. Many clinical studies have shown the efficacy of antihypertensive therapies, particularly the blockade of renin-angiotensin system, to lower the abnormal urinary protein excretion. Moreover, control of blood pressure and proteinuria slow the rate of renal function decline and in some cases even lead to recovery of kidney function avoiding the need for renal replacement therapies. The set of measures to achieve these results encompasses the term of "renoprotective therapy". However these achievements have been obtained in the setting of clinical trials, and need confirmation in the daily clinical practice. To this purpose a standardized multidrug intervention model that aims at normalizing the excretion of urinary proteins and stabilizing the renal function has been developed for the outpatient-clinic and named "Remission Clinic". The applicability of this protocol is aimed for all nephrology and diabetology centers. Through the use of a dedicated database computer network, it will be possible to share clinical, laboratory and treatment data, recorded for each patient enrolled in the Remission Clinic program. With this system, it will be possible to verify if the multidrug approach of the Remission Clinic will allow to improve the clinical course of chronic proteinuric nephropathy. All participants (centers) may access to the Remission Clinic website developed, updated and maintained by the Department of Bioengineering of the Mario Negri Institute, Bergamo, Italy.
Aim: To investigate whether cholecalciferol (4800 U/daily) or placebo for 16 weeks reduces proteins levels associated with vascular calcification (osteoprotegerin, osteopontin, osteocalcin) in patients treated with peritoneal dialysis and 25(OH) vitamin D deficiency.
This study will investigate the function of the immune system in people with chronic kidney disease (CKD) compared to people with normal kidneys. The investigators will use standard vaccines - the seasonal flu vaccine and pneumococcal polysaccharide (Pneumovax) vaccine - to examine how the immune system responds to challenge. All subjects will receive these recommended vaccines as part of routine care. Blood and urine samples will be collected and tested at different time points to look at how the immune response develops to these vaccines and if there are any differences between people with CKD and those without. This will help us understand how CKD affects the function of the immune system.
In stage 3 chronic kidney disease (CKD) the risk of death due to cardiovascular causes is high and greatly exceeds the risk of progression to end stage renal failure. This high cardiovascular risk is predominantly due to sudden cardiac death and heart failure, manifestations of left ventricular hypertrophy and fibrosis. Aldosterone appears to play an important role in the causation of this myocardial disease both by direct inflammatory and fibrotic myocardial effects and via increased arterial stiffness due to hypertrophy, inflammation, and fibrosis within the media of large arteries. Levels of aldosterone are high in CKD despite sodium overload and treatment with angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) drugs due to the twin phenomena of aldosterone escape and breakthrough. In a previous British Heart Foundation funded study, Birmingham investigators showed that the addition of the mineralocorticoid receptor blocker (MRB) spironolactone to background therapy with ACE inhibitors or ARBs caused reductions in the prognostically important parameters of arterial stiffness and LV mass. Because spironolactone therapy was also associated with significant falls in arterial pressure it remains possible that these effects were mediated simply by blood pressure reduction. In this multi-centre, randomised controlled study, the effects of treatment with spironolactone on LV mass and arterial stiffness in patients with stage 3 CKD on established ACE or ARB therapy will be compared to those of chlortalidone, a control anti-hypertensive agent. Early stage chronic kidney disease is highly prevalent and new, cost effective treatment strategies are required to reduce cardiovascular risk. This study is designed to provide the rationale for a larger study of morbidity and mortality with MRB therapy in early stage CKD.
The primary objective is to evaluate the impact of an AKI Follow-up Clinic on major adverse kidney events (MAKE) in comparison to hospitalized patients surviving an episode of AKI who are not exposed to the AKI Follow-up Clinic intervention.
Central venous catheters (CVCs) are used for vascular access by approximately 56% of our 380 hemodialysis (HD) patients at the Capital Health Renal Program. The major complication of these catheters includes thrombosis and infection. Catheter locking solutions such as recombinant tissue plasminogen activator (rt-PA), Alteplase (Cathflo®) are used to treat and prevent clotting of the catheter during HD treatments and during the interdialytic period. Evidence to guide the use of rt-PA is limited. This quality assurance project will compare the effectiveness and cost of an intensive versus a standard catheter dysfunction protocol for rt-PA in HD patients.
The eGFR-C study will assess the accuracy of current and alternative tests of kidney function against a reference test in people with moderate (stage 3) chronic kidney disease (CKD).
This study evaluates the efficacy and safety of deferred dialysis initiation in Chinese population. 16 tertiary hospitals across China will be randomly assigned into routine and deferred dialysis groups.
Control of blood pressure (BP) is the first thing to do in the management of chronic kidney disease (CKD). Although guidelines suggest the optimal blood pressure level, it is hard to assess BP correctly during the office visit. Often there is a discrepancy between office BP and out-of-office BP, including home BP and ambulatory BP. Recent study reported that as many as 34% of Korean CKD patients had masked hypertension, which means high BP by ambulatory BP monitoring but normal BP by conventional office BP measurement. This study aims to evaluate the effect of ambulatory BP-guided BP management on the clinical outcome of CKD, compared to the conventional management using office BP.
