Active clinical trials for "Renal Insufficiency, Chronic"

Kidney disease patients have a variety of bone disorders that result in bone loss and fractures. The mechanisms of these bone disorders are not clear but may be related to abnormal modification of a bone protein known as collagen. Therefore, the investigators are conducting this research study to identify underlying mechanisms that are responsible for the disruption of bone collagen and determining whether the abnormal bone collagen impairs bone strength. The investigators intend to identify these mechanisms through studying relationships between kidney disease and bone strength via bone imaging, bone biopsy and non-invasive measures from blood and skin.

This is a pilot study to test the utility of an integrated approach in the management of the anemia of chronic kidney disease through the administration of both an erythropoietic stimulating agent and iron. Subjects will be studied for 6 months during which all iron dosing will be recommended using a computer based tool using model predictive control. Comparisons will be made to the 6 months prior to enrollment in to the study.

This two-year pilot study will test whether a one-page "Jumpstart Form" will affect goals-of-care discussions in the hospital. This form will be provided to clinicians and will include patient-specific information about preferences for goals-of-care communication and for care, as well as tips to improve this communication. Jumpstart forms will also be provided to patients or, if they are unable to communicate, their surrogates/family members. The information on the form will be obtained from questionnaires. The form is tailored to help patients and surrogates talk with clinicians about goals of care. This study is based on a successful application of Jumpstart Form in the outpatient clinic setting.

While there are proven therapies that slow CKD progression, these therapies can at times be harmful and costly. The ability to accurately predict the risk of CKD progression to ESRD would be extremely valuable. The short term versus lifetime risk of CKD progression should be taken into account when making risk based clinical decisions. In a representative CKD practice, the investigators compared the short term and lifetime risk assessment in our stage 3 CKD patients to determine whether decisions based on a short term risk assessment would underestimate the lifetime risk of CKD progression. The investigators also applied the short term risk assessment to our stage 4 CKD patients to determine the frequency with which ESRD risk may be overestimated in CKD stage 4.

Chronic Kidney Disease (CKD) is associated with bone changes and very high fracture rates. A component of bone is marrow. Bone marrow fat is increased in patients with CKD compared to those in the normal population of the same age. It is not clear if there will be changes in the marrow fact content in those with CKD on Pioglitazone. In people with normal kidney function, thiazolidinedione group of drugs have had variable effects on bone marrow fat content, as measured by MRS. This is important as changes in marrow fat are likely related to changes in the bone in patients with chronic kidney disease.

The purpose of this Delphi study is to identify priority outcomes for self-management in earlier (non-dialysis) stages of CKD from the perspectives of different stakeholder groups in the UK. The findings of this study will be used to inform outcome measure selection for research and clinical evaluations of self-management resources and to support implementation, commissioning and uptake.

Hemodialysis patients display among the lowest level of daily activities and decline of functional abilities is highly correlated with mortality. Perdialytic exercise during hemodialysis procedure is now part of the patients' routine care and appears to be a solution to struggle against the functional skills decrease. Our team was able to demonstrate that beyond muscle mass, muscle strength and physical activity were essential determinants of morbidity and mortality of dialysis patients. The AIDER Santé medical team has set up an assessment of physical activities and muscle strength in the Montpellier and Nimes centers. In order to rehabilitate muscle strength and endurance, perdialytic exercise may be prescribed. Its effectiveness can be appreciated by measuring the SPPB score (Short Physical Performance Battery). Recent studies established that combined training including resistance and endurance exercises was the most effective to improve functional performance. In AIDER Santé dialysis centers, the two mainly used exercise approaches are distinguished by the time distribution of the two types of exercise: the first plans to practice both types of exercise at each session (continuous program), the second plans to alternate a week of resistance exercise with a week of endurance exercise (discontinuous program). It is established that the rehabilitation of the hemodialysis patient must include both resistance and endurance exercises, but the combination of these exercises during the same session is potentially at the origin of an interference phenomenon, limiting neuromuscular adaptations specific to each effort. Therefore, the main hypothesis of the project is that the temporal separation of resistance and endurance exercises in a discontinuous program could optimize the functional gains of combined rehabilitation and therefore be more effective than a continuous program generating a phenomenon of interference.

Investigators are building an empirical evidence base for real world data through large-scale replication of randomized controlled trials. The investigators' goal is to understand for what types of clinical questions real world data analyses can be conducted with confidence and how to implement such studies.

Chronic kidney disease (CKD) is a risk factor for the development of cardiovascular disease, which increases the risk of death after cardiac surgery. High interleukin 6 (IL-6) blood levels is commonly observed in patients with CKD, and this is particularly high after cardiac surgery. High IL-6 levels are also associated with increased long-term mortality rate after cardiac surgery. To date, the use of ultrafiltration or endotoxin adsorption systems were not found to improve the clinical outcome, although able to reduce the inflammatory mediators concentrations. In the last years, a new extracorporeal hemadsorption filter (CytoSorb) has been developed for removal of inflammatory cytokines and it has been approved by the European Union. However, data lack about the impact on clinical outcome of the use of CytoSorb in patients with CKD undergoing cardiac surgery with cardio-pulmonary bypass (CPB). The investigators have therefore designed this pilot prospective randomized trial to evaluate the efficacy the intraoperative use of CytoSorb for cytokines removal to prevent the inflammatory response associated with the cardiac surgery and complications in patients with CKD.

Chronic kidney disease is widespread in the western world with bacterial infection and sepsis as common complication. It has been shown that innate immune defence, represented by dysfunction of neutrophil granulocytes, is impaired in chronic kidney disease. Another impact of chronic kidney disease on innate immunity is the chronic activation of neutrophils leading to high levels of inflammatory cytokines, thus contributing to protein oxidation. Oxidation of human serum albumin (HSA), the major plasma protein, occurs in chronic kidney disease and leads to further activation of neutrophils. Another important impact of HSA oxidation is the decrease of its binding capacity leading to impaired detoxification ability of albumin. This includes reduced clearance of endotoxin, a major component of the gram negative bacterial cell wall. Circulating endotoxin is recognized by complex formation with lipopolysaccharide binding protein (LBP) followed by binding to CD14 and toll-like receptor (TLR) 4. High systemic endotoxin levels occur in chronic kidney disease and may be the result of decreased clearance ability of HSA and increased gut permeability in combination with intestinal bacterial overgrowth. High systemic endotoxin is associated with worse outcome in several diseases and could be used as predictor for mortality in chronic kidney disease patients. Endotoxemia in renal insufficiency leads to impaired neutrophil function and to increased albumin oxidation. Oxidized albumin is not able to bind endotoxin adequately any more, which leads to a further increase in oxidative stress and neutrophil dysfunction, resulting in a vicious cycle. 195 patients with renal dysfunction will be enrolled and divided into 5 groups. Additionally, samples of 25 age and sex-matched healthy controls will be collected. This concept will change the understanding of several aspects of chronic kidney disease and will potentially help to stratify patients into different groups at risk according to their endotoxin status, and their immune and albumin dysfunction. The results of this study will have important implications into the development of novel therapeutic strategies
