Filter by:The aim of this study is to determine the feasibility of running a phase III double-blind, double-dummy randomised controlled trial comparing Depo-Medrone 120mg intramuscular injection vs. Anakinra 100mg subcutaneous injection for 5 days for the treatment of acute gout attacks in patients with chronic kidney disease as defined by a eGFR < 60mls/min/1.73m2 and ≥ 30mls/min/1.73m2.
The aim of the present study is to study the expression of the various phosphate transporters in patients with normal or moderately impaired renal function or in patients on dialysis. In particular, the investigators want to clarify whether NaPi-IIb expression level decreases in CKD patients, which would render it a potentially inadequate pharmaceutical target in these patients.
While the duration of renal transplant function has increased over the last decade kidney transplanted patients (KTP) still exhibit a fracture risk 4 times higher than in the general population. Fracture risk remains increased despite the improvement of immunosuppressive therapies (IST) that allowed the reduction of steroid administration. Potential explanations for this could be 1) that Chronic Kidney Disease (CKD) induces renal osteodystrophy that occurs before kidney transplanted, impairs bone metabolism and promotes bone fragility ; 2) that kidney transplanted patients are older and older (14% of kidney transplanted patients were older than 70 in 2011 in France), ageing being a major risk factor for fractures 3) IST, besides steroid, may have deleterious effects on bone and 4) that secondary hyperparathyroidism, a risk factor of fractures, persists after kidney transplanted . Thus, the pathophysiology and epidemiology of bone fragility of kidney transplanted patient remains insufficiently characterized. Despite these data, and contrarily to what is done for patients candidates for cardiac transplantation, there is no general consensus for performing bone evaluation before kidney transplanted . Thus it's necessary to individualize the management of bone fragility and prevent fractures according to strategies that remain to be defined, provided that patients at risk are better detected.
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).
Magnetic resonance imaging (MRI), as a non-invasive and non-contrast enhanced technique, has the potential to improve patient health care and management. The overall objective of proposed project is to: 1. develop, customize, and optimize anatomic and functional MRI methods, 2. explore the use of MRI methods to study CKD and evaluate post-transplant kidneys, and 3. investigate the potential of MRI in the diagnosis, prognosis, and monitoring of the progression of renal dysfunction. In addition to direct studies of the kidney, brain MRI studies will also be performed to identify the cerebrovascular and cognitive effects of chronic renal function deficiency and medical treatment (e.g. hemodialysis and immunosuppression). The brain and kidneys have similar vascular bed, and both are susceptible to vascular injury, which provides the pathological basis for the widely recognized association of reduced renal function with prevalent cerebrovascular diseases (CVDs) and cognitive impairment (CI). The MRI methods in the brain will be applied to explore the origins for widely observed CVDs and prevalent cognitive impairment (CI) in kidney disease patients.
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.
Myocardial fibrosis is the fundamental substrate for the development of heart failure. Cardiovascular magnetic resonance (CMR) allows non-invasive assessment of myocardial fibrosis based on late gadolinium enhancement (LGE) and T1 mapping. Patients: Prospective longitudinal observational multicenter study of consecutive patients with suspected or known non-ischemic cardiomyopathy. Imaging: Non-invasive measures of myocardial fibrosis: native T1, extracellular volume fraction (ECV) and LGE. Primary endpoints: all cause and cardiovascular mortality. Secondary endpoints: arrhythmic composite and HF composite endpoints.
Patients with severe chronic kidney disease (CKD) are at a great risk for infection due to their immune system being suppressed. Pneumococcal infection is particularly common and often results in death due to inflammation of lung (pneumonia) or the whole body (sepsis). This infection can be prevented using vaccines which help build protective immunity. The currently recommended pneumococcal vaccine (Pneumovax), however, is often inefficient in this group of patients. There is thus an urgent need to improve the existing vaccination policy. The goal of this research is to optimize pneumococcal vaccination of patients with severe CKD. Many patients suffering from CKD have already been vaccinated with Pneumovax. Because this vaccine has low immunogenicity in immunocompromised individuals, they may still develop infection. A new vaccine, Prevnar13, has superior immunogenicity and has been recently approved for immunization. There is, however, no specific policy regarding immunization of adult CKD patients, and it is furthermore unknown whether previous Pneumovax immunization negatively affects immune response to Prevnar13. In order to test whether previous immunization with Pneumovax affects the immune response of severe CKD patients to Prevnar 13, the investigators will immunize two groups of adult stage 4 and 5 CKD patients with one dose of Prevnar 13 and will assess their initial immunological response, its longevity, and vaccine safety. The first group will consist of patients who had been previously immunized with Pneumovax, and the second group will include participants with no history of pneumococcal vaccination. Antibody levels and opsonophagocytic activity (OPA) will be quantified. The longevity of the immune response will be assessed. As a secondary objective, the immune response will be analyzed in the context of demographic and clinical characteristics of the vaccinated participants.
This study investigates the effect of vitamin D deficiency on drug metabolism and transport in patients with chronic kidney disease (CKD) and in healthy controls. The central hypothesis is that vitamin D concentrations independently affect metabolism and transport function in CKD patients. An over-arching goal of this proposal is to make drug therapies safer and more effective to reduce the significant morbidity and mortality in patients with CKD.
This observational, multi-center, open-label, prospective study will evaluate the relationship between serum interleukin-6 (IL-6) and C-reactive protein (CRP) levels and methoxy polyethylene glycol-epoetin beta dosage in participants with chronic kidney disease (CKD) on dialysis. Participants will be recruited who are on stable methoxy polyethylene glycol-epoetin beta maintenance therapy or will initiate therapy with methoxy polyethylene glycol-epoetin beta.
