Active clinical trials for "Kidney Diseases"

The investigators hypothesize that the chronic kidney disease patients who suffer from vitamin D deficiency will be benefit from given Vitamin D2 because coronary artery calcification and hyperparathyroidism will be improved.

End stage renal failure (ESRF)describes an irreversible loss in renal function. The majority of these patients will opt for haemodialysis (HD)as their chosen method of renal replacement therapy (RRT). Arteriovenous fistulae (AVF) are the optimal method of achieving vascular access to permit HD. AVF are created with a small surgical procdure to join the artery and vein together. Over the next 6- 8weeks after surgery the AVF should grow ("mature") into a vessel suitable for needles to be inserted for dialysis. Unfortunately however, around 24% - 35% of AVF fail at an early stage. Some anaesthetic techniques can influence intraoperative blood flow and venous diameter, factors which are associated with fistula success. There remains no conclusive evidence that any particular anaesthetic technique can significantly influence long term surgical outcome. This study aims to investigate whether a regional, compared to local, anaesthetic technique can affect fistula patency.

Urinary biomarkers (u-NKCC2, u-ENaC-gamma and u-AQP2) reflects the activity of the sodium- and water channels in the human kidney. Changes in the sodium-and water channel activity can be induced by blocking the sodium channels with diuretics in healthy subjects

Optical coherence tomography (OCT) is a rapidly emerging imaging modality that can function as a type of "optical biopsy", providing non-invasive cross-sectional images of tissue architectural morphology in situ and in real-time. This proposal will demonstrate that OCT has the ability to provide novel and valuable histopathological information regarding donor kidneys that can be used to predict post-transplant renal function. These investigations will result in a major breakthrough in increasing the number of healthy kidneys available for transplantation by making the most efficient use of available donor kidneys, eliminating the possible use of bad donor kidneys, providing an accurate measure of expected post-transplant renal function, and allowing better distinction between post-transplant immunological rejection and ischemic-induced acute renal failure.

Using a randomized controlled trial design, two hydration protocols for the prevention of contrast medium-induced nephropathy will be tested.

Treatment of prednisone plus cyclophosphamide may be superior to treatment of prednisone alone in patients with advanced-stage IgA nephropathy.

The kidneys have numerous salt and water channels and play a major role in the regulation of sodium and water. We do not know how these channels work in certain water and sodium accumulating medical conditions. The purpose of this study is to identify and measure the activity in the water and sodium channels by measuring urine biomarkers/proteins in young healthy subjects.

The purpose of this study is to determine if the adoption of a chronic care model in conjunction with tele monitoring and case management can reduce the risk of death, hospitalization, emergency room visits, or admission to a skilled nursing facility in patients with chronic kidney disease compared to usual care.

This study will use an adapted education worksheet to support patient-centered chronic kidney disease (CKD) communication, shared decision making, and patient engagement and will test its impact on intermediate patient modifiable characteristics in a primary care practice with patients who have pre-dialysis CKD. The study team will enroll up to 100 patients with chronic kidney disease (CKD) from a primary care clinic to start. Patients will receive the intervention, which consists of the physicians using the education worksheet during appointments with patients, and patients and providers will complete surveys about its use and to measure impact on knowledge and other areas related to patient outcomes. Once initial user testing is complete, the study team plans to submit an amendment to expand on this trial and incorporate comparison sites. This will be submitted and receive IRB approval prior to participant involvement. The study hypothesis is that patients who receive the intervention will have greater knowledge about their CKD diagnosis, higher satisfaction with provider communication, and higher scores related to managing CKD to keep themselves healthy compared to control populations.

Forty patients with diabetic nephropathy will be treated with colchicine up to 2 mg, or placebo, for 18 months. A follow up will be performed after 12 additional months. The primary outcome will be a significant reduction or stabilization of proteinuria during the 18 month treatment period.
