Individuals receiving dialysis are at risk of heart failure and heart related death. There is an urgent need for treatments that reduce the risk of these problems in patients that require dialysis. Spironolactone is a pill used to prevent heart failure and related deaths in patients that do not require dialysis. It works by blocking a hormone (aldosterone) in your body that causes high blood pressure and can damage the heart. Although spironolactone is very effective in patients that do not require dialysis, we do not know if spironolactone is effective in dialysis patients. Our research will help determine if spironolactone reduces heart failure and heart related deaths in dialysis patients. The purpose of this study is to determine if spironolactone reduces death or hospitalization for heart failure and is well tolerated in patients that require dialysis.

Arterial calcification within the coronaries and other vessels is greatly accelerated among patients with chronic or end-stage kidney disease. The mechanisms leading to increased calcification are unknown, but include hyperphosphatemia, hyperparathyroidism and altered vitamin D metabolism. Moreover, recent data demonstrates that circulating carboxy fragments of PTH (7-84) are physiologic antagonists of intact PTH (1-84) and may directly contribute to vascular calcification. Current PTH assays no not distinguish between intact and carboxy PTH fragments leading to an overestimation of intact PTH levels. Because second generation PTH assays detect both 1-84 and 7-84 PTH fragments, the use of vitamin D analogues to treat secondary hyperparathyroidism could lead to excessive suppression of 1-84 and a preponderance of carboxy PTH fragments. Moreover, increased administration of vitamin D analogues amy contribute to vascular calcifications. To investigate these questions, we plan to investigate the effect of managing new ESRD patients using conventional and third generation PTH assays on vitamin D administration and the development of coronary calcification. Hypothesis #1: Clinical management of secondary hyperparathyroidism in new hemodialysis patients using the Scantibodies 1-84/7-84 PTH ratio for one year will reduce the amount of Vitamin D administration resulting in reduced coronary calcification compared to patients in which PTH management is accomplished by conventional, second generation PTH assay.

Patients undergoing chronic dialysis are at a substantially increased risk of cardiac death. The reasons for this excess cardiovascular mortality are only partly understood. Classical complicated artherosclerotic disease does not appear to be the primary cause of cardiac death in chronic dialysis patients. In fact, the predictive potential of classic cardiovascular risk factors such as hypertension, obesity and hyperlipidemia appears to be reduced in dialysis. In contrast, in a series of pilot studies we found cardiac biomarkers to adequately reflect dialysis induced myocardial stunning, progressive cardiovascular disease, and the risk of death. To extend and corroborate these results, we are planning a large, prospective, observational study enrolling unselected hemo- and peritoneal dialysis patients. The proposed study, its power calculation and hypotheses are based on our pilot studies
NCT03010072
This is a single-center, prospective, open-label, controlled, randomized, cross-over study in 34 prevalent end-stage renal disease patients on chronic hemodialysis treatment with hyperphosphatemia.
NCT02977117
The purpose of this trial is to examine the effect of increasing dialyse magnesium on serum calcification propensity in subjects with end-stage renal disease treated with haemodialysis.
NCT02866214
The Purpose of this study is to determine if the Febuxostat has an effect on endothelial dysfunction on hemodialysis patients.
NCT03054454
Observational studies clearly show that people with diabetes and end-stage kidney failure have an increased risk of foot ulceration and leg amputation. However, there is very little evidence on addressing this problem. Diabetes foot care teams have been shown to reduce hospital admissions, length of stay and leg amputation in people with diabetes. Since their introduction at The James Cook University Hospital (JCUH) major diabetes-related leg amputation rates have fallen by 86 percent (1995 to 2010). People with diabetes and end-stage kidney failure require haemodialysis (blood cleaning) 3 times per week for several hours each time. This time commitment makes it difficult to attend other clinical appointments. An audit at JCUH shows that this population fails to attend the normal diabetes foot services. This project aims to reduce the incidence of foot disease in people with diabetes and end-stage kidney failure on dialysis. The investigators will set up a podiatry-led intervention within the dialysis unit to prevent and promptly treat foot disease in this population. This will involve foot risk assessment, risk reduction and treatment during dialysis. The intervention will involve diabetes consultants, podiatrists, vascular and orthopaedic surgeons . In this way the investigators hope to reduce leg amputation, hospital admission, procedures to unblock arteries and death in this high risk group. The study will run in the dialysis unit at JCUH. Patients will be divided into two groups: those attending for dialysis on a Monday, Wednesday and Friday will form the treatment group and those attending on a Tuesday, Thursday and Saturday will continue to be managed as at present. The investigators will collect data from patient health care records looking in particular at leg amputations, hospital admissions due to foot problems, foot surgery and operations to unblock arteries.
NCT03023748
This study aims to provide intravenous paritcalcitol treatment for the sick and poor hemodialysis patients with severe secondary hyperparathyroidism (SHPT) resistant to existing vitamin D analogs therapy or with hypercalcemia precluding the use of existing vitamin D analogs. The study aims to evaluate the effect of paricalcitol on control of SHPT, biochemical parameters of chronic kidney disease-mineral bone disease, cardiac parameters, vascular calcification and stiffness parameters and nutrition status in patients receiving chronic hemodialysis treatment.
NCT02957877
There is a lack of data in the literature about the use of low-molecular weight heparin (LMWH) as anticoagulation for nocturnal home hemodialysis (NHHD). This study aims to evaluate the efficacy and safety of LMWH, administered by infusion method, as compared to unfractionated heparin as anticoagulation for NHHD treatment.
