Filter by:Background: - Genetic variation in a particular chromosome is a major contributor to the increased risk for kidney disease that is common in people of African descent, although the specific gene, mutations, and other aspects of the variations remain to be determined. By studying the outcomes of kidney transplant in donors and recipients of African descent, researchers hope to better understand the effects of this genetic variation on the success of kidney transplants. Objectives: - To examine possible connections between genetic variations and kidney transplant outcomes for donors and recipients. Eligibility: - Participants in kidney transplant where both donor and recipient were of black African descent. - Eligible transplants include both living donor and deceased donor. Design: - The study will involve one visit of up to 8 hours. - All participants will provide a detailed personal and family medical history. - All participants will provide blood and urine samples, including a 24-hour urine collection, to test kidney function and collect material for genetic testing. - Donor participants will also have a magnetic resonance imaging (MRI) scan of their remaining kidney.
The purpose of this study is to determine the in-vivo ultrafiltration coefficient for different sizes of xevonta High-Flux dialyzers following FDA guidelines.
The purpose of this study is to find out how chemicals in the blood of patients with chronic kidney disease affect how medications are removed from the body. The patient will take one dose of three different drugs, one on each week, for a total of three single doses. The investigators want to find out if these three different medications are affected in different ways by the chemicals in the blood of patients with kidney disease.
Ultrasound (US) is widely used as a diagnostic tool in a hospital setting. In a medical department, diagnosis like heart failure or most kinds of heart diseases, hypervolemia, hypovolemia, pleural effusion, pericardial effusion, ascites, diseases in the gall bladder/bile tract, urine tract and venous thrombosis are common. US is the key diagnostic tool in these diagnosis, and on early diagnosis is crucial both on behalf of the patients well-being, and for hospital logistic reasons. 1. The aim is to study the clinical use of pocket sized US as a screening diagnostic tool in an department of internal medicine. Method: All patients admitted (in certain preset periods) to Department of medicine will be screened with pocket sized US by expert user. Changes in diagnoses, as well as medications as a result of US screening will be the endpoints. US findings will be validated against standard echocardiography, or standard US/CT/MRI performed at the Radiological department. 2. The aim is to study the clinical use of pocket sized US as a screening diagnostic tool in a department of cardiology. Method: All patients admitted (in certain preset periods) to Department of cardiology will be screened with pocket sized US for heart disease, pericardial and pleural effusion. Examinations by expert users. Specific findings could be myocardial dysfunction as heart failure, cardiomyopathies, regional dysfunction due to ischemia, valvular dysfunction, atrial enlargement, and pleural/pericardial effusion. Changes in diagnoses, as well as medications as a result of US screening will be the endpoints. US findings will be validated against standard echocardiography in all. 3. As in 1), but examination by non-expert users compared to expert users.
The investigators evaluated predictive values of myocardial fatty acid metabolism and insulin resistance for cardiac death of hemodialysis patients with normal coronary arteries.
The purpose of the study is to evaluate the safety and efficacy of intravenous (IV) ferumoxytol compared to IV iron sucrose for the treatment of iron deficiency anemia (IDA) in participants with chronic kidney disease (CKD).
The purpose of this study is to characterize the safety and efficacy of repeat doses of compound 1278863A in subjects with anemia.
Does remote ischemic preconditioning (RIPC) induced by a brief period of occlusion of blood flow to the lower extremity prior to organ recovery in deceased donors, improve short and long term outcomes after transplantation of kidneys, livers and pancreas? To test this hypothesis deceased organ donors will be randomized to receive either RIPC or No RIPC before organ recovery. RIPC will be induced in the operating room after commencement of procurement surgery. RIPC will be induced by tourniquet-induced occlusion of blood flow to the lower extremity for 10 minutes in each side, for a total duration of 20 minutes. The remainder of the organ recovery and organ preservation will be as per standard of practice. Recovered livers, kidneys and pancreas will be transplanted into allocated recipients. Transplantation and patient management after transplantation will be as per standard of practice. Organ-specific function and cell injury parameters will be utilized to assess the early postoperative outcomes of individual organs and recipients. Long term outcomes will be assessed by graft and recipient survival.
Hyperparathyroidism (HPT) is common in people with a kidney transplant. Patients with HPT often have high parathyroid hormone (PTH) levels and may have large parathyroid glands in the neck. Patients with HPT can develop bone disease (osteodystrophy). This bone disease can cause bone pain, fractures, and poor formation of red blood cells. Other problems from HPT may include increases in blood levels of calcium (hypercalcemia) and low blood levels of phosphorus (hypophosphatemia). The high calcium levels may cause calcium to deposit in body tissues. Calcium deposits can cause arthritis (joint pain and swelling), muscle inflammation, itching, gangrene (death of soft tissue), heart and lung problems or kidney transplant dysfunction (worsening of kidney transplant function). The purpose of this study is to evaluate the effects of cinacalcet (Sensipar/Mimpara) on high calcium levels in the blood in patients with HPT after a kidney transplant.
ABSTRACT Background: It is well recognized that excess dietary salt intake plays a major role in the development of hypertension. Chronic Kidney Disease (CKD) is associated with excess salt and water retention (excess volume) which is associated with hypertension. Hypotheses: Hypothesis 1: Dietary salt restriction will improve volume status in subjects with CKD stages 3-4 as assessed by Bioelectrical Impedance Analysis (BIA). Hypothesis 2: Dietary salt restriction will result in improved blood pressure control in patients with CKD stages 3-4. Hypothesis 3: Dietary salt restriction will decrease albuminuria in patients with CKD stages 3-4. Patients and Trial Design: This randomized crossover pilot study is designed to assess the effect of salt restriction on volume status in patients with CKD stages 3 and 4. Subjects will be randomized to a treatment order: (1) 4 weeks of salt restriction of <85 mmol sodium per day, a 2 week washout period, and 4 weeks of usual salt diet, OR (2) 4 weeks of usual diet, 2 weeks washout, and 4 weeks of salt restriction. Patients will receive dietary counseling in person at each study visit and at weekly intervals by phone calls from study dieticians. At weeks 0, 4, 6 and 10, patients will undergo assessments for (i) physical examination with assessments for weight, blood pressure, pulse, anthropometrics and a standardized clinical assessment of volume status. (ii) volume status using bioelectrical impedance analysis (BIA) (iii) 24-hour urine testing for, albumin, creatinine and aldosterone Every 2 weeks throughout the study, a 24-hour urine sodium will be measured for compliance, and serum electrolytes will be assessed for safety. Data Analysis: BIA measurements in the low salt group will be compared with the regular diet group using the standard linear model analysis for 2x2 crossover trials. Additionally, 24-hour ambulatory and static blood pressure and 24-hour urine aldosterone levels will be compared between the two groups. Future Implications: A significant reduction in the degree of volume expansion (as assessed by BIA) and blood pressure as a result of a salt restricted diet would have implications for renal and cardiovascular protection and would warrant confirmation by a larger randomized trial.
