Filter by:This study aims to find out whether people with chronic kidney disease [CKD] should take low dose aspirin to reduce the risk of first heart attack or stroke (cardiovascular disease [CVD]). CKD is common and is associated with an increased risk of CVD. CVD is caused by small blood clots and aspirin thins the blood to reduce the risk of such clots developing but it also increases the risk of bleeding. Aspirin is recommended to prevent further CVD in people who have already had a first CVD event (so called secondary prevention). Here the investigators want to study the use of aspirin as primary prevention in people with CKD who have not had a CVD to prevent the first event, to assess whether the potential benefits exceed the risks. Eligible patients will be recruited from their United Kingdom (UK) general practices and allocated by chance to be prescribed once daily low dose aspirin or usual care only. Follow-up will be for several years both electronically (for general practice, hospital and mortality data) and by annual questionnaires to ascertain CVD and bleeding events.
Kidney function in patients with atrial fibrillation (AF) is tending to decline over a time which is clearly demonstrated in clinical studies. Renal impairment is a risk factor for stroke, its progression is associated with unfavorable prognosis. So preserving kidney function should be considered as a one of priorities when choosing treatment strategies which is especially important in patients with existing chronic kidney disease (CKD) or in patients who have risk of its development. This is especially relevant for the patients with type 2 diabetes mellitus (T2DM) and with CKD who can be considered as a group of risk for rapid kidney function decline.
This study is to assess the effect of 48 weeks administration of Renamezin capsule on prevention of sarcopenia in pre-dialysis patients with chronic kidney disease.
This study will perform multi-parametric renal MRI in 70 patients with a renal transplant who are undergoing a clinically indicated biopsy of their transplant. The aim of this study is to compare findings on renal MRI with those seen on histology.
Chronic kidney disease is a systemic disease that affects not only renal function, but also, several organs, bringing social, psychological and physical impact to the patients under this condition. Due to long periods of inactivity during hemodialysis, electrical stimulation becomes a feasible alternative for development physical activity in these patients. Objective: Assess the efficacy of combined low and high frequency electrical stimulation in peripheral muscle function during hemodialysis. Methods: A randomised double-blind clinical trial with chronic kidney disease patient's under hemodialysis, whose will be allocated in four groups: low frequency electrical stimulation (LF) ; high frequency (HF); low and high frequency (LHF); and sham electrical stimulation. The groups will receive quadriceps application bilaterally, for sixty minutes, three times a week, for two months. In the intervention groups will be used highest intensity tolerated by the individual, and in the sham will be maintained the minimum intensity after beginning of the perception of the electric current. The individuals will be evaluated for anthropometry, functional capacity, quality of life and biochemical parameters.
Renal impairment is common in patients with chronic hepatitis B infection. For those taking nucleotide analogues, renal toxicity of adefovir disoproxil (ADV) and tenofovir disoproxil fumarate (TDF) is a significant concern in chronic hepatitis B (CHB) patients. Early observational clinical data suggested that telbivudine (LdT) might have renoprotective effects. In this prospective study, consecutive CHB patients on combined lamivudine (LAM)+ADV/TDF are switched to LdT+ADV/TDF at recruitment and are followed up for 24 months. Estimated glomerular filtration rate (eGFR) is calculated with the Modification of Diet in Renal Disease (MDRD) equation. The effects of LdT on cell viability and expression of kidney injury or apoptotic biomarkers are investigated in cultured renal tubular epithelial cell line HK-2.
This study aims to describe sex specific differences of the hemodialysis population in Austria, to quantify sex specific differences in treatment and outcomes in hospitalized patients with chronic kidney disease and to examine decision making by doctors and patients with regards to hemodialysis initiation. To adequately serve the needs of these research questions, the study is divided into 3 parts (sub-studies). 1. Description and analysis of sex-specific differences in renal replacement therapy in Austria. 2. Description and analysis of the competing risks of death versus renal replacement therapy initiation in the chronic kidney disease population by sex. 3. Analysis of sex differences in renal replacement therapy initiation decisions, emphasizing patient perception and socio-economic differences.
Premature cardiovascular disease (CVD) is the leading cause of death in patients with kidney disease (CKD). Excessive cardiac mortality is thought to be secondary to non-atherosclerotic processes, with left ventricular (LV) hypertrophy (LVH) and remodelling being the predominant phenotypical features. Along with other risk factors, subclinical ischaemia and haemodynamic perturbations associated with haemodialysis (HD) are thought to contribute to the ultimate development of LV systolic and diastolic dysfunction. The development of these adverse features reflects a specific cardiomyopathy due to CKD and subsequently, to uraemia. Patients receiving hemodialysis (HD) have a higher incidence rate of heart failure (predominantly with preserved ejection fraction), with phenotypically eccentric hypertrophic remodelling, systolic and diastolic dysfunction as well as high rate of interstitial myocardial fibrosis. Detection and ultimately reversal of the development of this CKD-related cardiomyopathy are important goals for improving the CVD, morbidity and mortality of CKD patients.The objectives of this study are, firstly, to investigate the complex myocardial phenotype in patients with various stages of CKD, secondly, to relate the CMR-measures to outcome, and thirdly, to be able to estimate the effects of chronic uremia/hypervolemia. Deciphering the predominant driver of remodelling on an individual level may help to personalise anti-remodelling strategies. Native T1 and T2 mapping imaging provide non-invasive imaging tools to detect myocardial fibrosis and oedema, respectively. Prognostic associations of these measures may clarify the relative prevalence of adverse phenotype and their relative contribution to adverse events and poor outcome. The role of chronic water retention and uraemia may be associated with interstitial myocardial oedema promoting further the remodelling process.
This extended access study will assess the long-term safety and tolerability of bardoxolone methyl in qualified patients with chronic kidney disease (CKD) who previously participated in one of the qualifying clinical studies with bardoxolone methyl. Patients will remain in the study until bardoxolone methyl is available through commercial channels or until patient withdrawal, whichever is sooner.
Mapping of magnetic relaxation within the myocardial tissue using T1 (and T2) mapping using cardiovascular magnetic resonance (CMR) are novel measures of quantifiable (scalable) myocardial tissue characterisation. Evidence suggests that myocardial mapping could be useful in detection of diffuse myocardial disease, complementing late gadolinium enhancement (LGE) as the tool for regional myocardial disease. A handful of studies, three single centre study of a single T1 index with outcomes and one multicentre study for all indices reported strong associations with all cause mortality and heart failure. These studies were based on a single-vendor platform and were using a single sequence. The main unknowns pertaining the successful translation of this technique and the transferability of the methodology beyond a single centre and lack of outcome evidence from broad and large populations. In this study, we will assess the diagnostic accuracy of T1 (and T2) mapping measurements in health and disease, and the prognostic relevance of T1 mapping measurements by associations with outcome. This study is builds upon/integrates the evidence of the NCT02407197 study, which remains active for follow-up, but is currently no longer recruiting.
