Active clinical trials for "Renal Insufficiency"

Prospective observational ultrasound study of native arterio-venous fistula for haemodialysis with venous pressure measurement using controlled compression ultrasound.

Research participants will be asked to undergo complete medical history, physical examination and blood tests. The purpose of these tests is to determine whether persons are predisposed to develop diabetes mellitus after kidney transplantation and also to make an early diagnosis if a patient develops diabetes mellitus. Medical information collected as part of the standard transplant evaluation and posttransplant medical care may be incorporated into this study. It is important to realize that research subjects will not be given an experimental drug as part of this study. After kidney transplantation, research subjects will be followed in the posttransplant clinic visits. The study will last up to 6 months. During this time the subjects may be asked to participate in clinical assessment visits (medical history and physical examination), and also during the third or fourth month after transplant will be asked to do a repeat glucose tolerance test.

Kidney dysfunction before and immediately after liver transplantation is common and leads to poorer outcomes, including prolonged need for post-operative intensive care, diminished graft survival, and greater risk of permanent kidney dysfunction and death. Blood creatinine level - the standard measure of kidney function - is suboptimal in people with advanced liver disease, overestimating kidney function by >20%. There is significant concern that liver transplant recipients are at higher risk of acute kidney injury (AKI) than we can currently predict. This study aims to identify superior tests (blood/urine or imaging) for kidney dysfunction, to enable improved treatment and patient outcomes. This study aims to recruit 80-100 consecutive patients admitted to the Scottish Liver Transplant Unit (SLTU), Royal Infirmary of Edinburgh (RIE) for liver transplant assessment over a 6 month period. Permission will be sought to record the results of routine tests performed by the NHS during this assessment week. These tests include: electrocardiograph (ECG), Computed Tomography (CT) liver and abdomen, cardio-pulmonary exercise testing (CPEX), pulmonary function tests (PFTS), routine haematology and biochemistry blood tests, 24 hour urine collection and body composition analysis. In addition, we will invite participants to attend the RIE clinical research facility (CRF) for a single visit (~2 hours) to perform extra research assessments. Blood and urine will be collected for biomarker analysis. Non-invasive assessment of cardiovascular function will be completed using cardiac bio-impedance and aortic pulse wave velocity. Examination of the blood vessels at the back of the eye will be performed using optical coherence tomography. A subgroup of 10 participants will undergo magnetic resonance imaging (MRI) of the kidneys using arterial spin labelling to identify dysregulated renal perfusion. Patients who are transplanted during the study timeframe will be asked to re-attend the CRF for repeat assessments at 6 weeks post transplantation.

Whole blood sample procurement study from pregnant women with signs and symptoms of Preeclampsia.

The rein registry collects case record data from patients with end stage renal disease followed in French Guiana. This allows to generate incidence and rates for terminal renal disease, mortality rates for each territory. The regional data are pooled in order to get national statistics for end stage renal disease and transplantation activity in order to adapt prevention to the main causes of renal failure and treatment and care infrastructure.

The primary objective of the study aims to evaluate frequence of acute renal insufficiency in patients with ST-segment elevation who need urgent coronary angiography in Ambroise Paré hospital. The secondary objectives are: identify factors of risks associated with the occurrence of acute renal insufficiency after coronarography. establish a preprocedure score, predicting of acute renal insufficiency after urgent coronary angiography in patients with ST+ acute coronary syndrome.

This is a prospective observational pilot study of patients under the care of the Royal Free Hospital with chronic kidney disease who have been established on regular thrice weekly haemodialysis treatments in a dialysis centre,to measure the changes in blood flow in the ear during haemodialysis.

Remote ischemic preconditioning reduces the incidence of contrast-induced acute kidney injury in patients undergoing elective coronary angiography. This study was designed to acquire long-term data of initially randomized patients in the RenPro Trial.

Analyze the various causes of breakdown of muscle fibers in hospitalized patients. Analyze the characteristics of these patients in Taiwan (including the drugs history, risk factors and the incidence of complications).

Patients living with diabetes mellitus have double the risk of kidney failure compared to patients without diabetes following use of dye in many x-rays and procedures to diagnose and treat narrowing of the arteries (blood vessels) in the heart that can lead to angina or a heart attack. Heart disease is the commonest cause of death in patients with diabetes. People with diabetes are more likely to need these tests/treatments. By identifying those at greater risk of kidney complications we may be able to make these tests/treatments safer and offer them to more patients with diabetes.
