Filter by:Kidney obstruction might be caused by a stone in the urinary tract. In case of accompanying fever or renal failure, an urgent drainage might be needed. This can be done either by placing an ureteral stent or a nephrotomy tube. Only limited number of studies examined the question which of the two is preferred. A debate exist regarding the effectiveness of each procedure to improve symptoms, renal function and treating an infection. Our goal is to resolve this debate and to state whether one way is preferred on the other.
Peritoneal dialysis patients are at increased risk of cardiovascular morbidity and mortality and are related to the presence of accelerated atherosclerosis. Our recent data showed that inflammation predicts mortality and cardiovascular death, independent of other cardiovascular risk factors in peritoneal dialysis patients. As a considerable proportion of peritoneal dialysis patients showed evidence of inflammation, it raises an important question as to whether anti-inflammatory treatment has any cardiovascular and survival benefit in these patients. The peroxisome proliferator-activated receptor-gamma (PPAR-g) agonist is a class of drug with insulin sensitizing property. Recent experimental and clinical studies demonstrated that this class of drug has anti-inflammatory and anti-atherosclerotic properties other than insulin sensitizing effect in type 2 diabetics. We therefore hypothesize that modulation of the PPAR-g activity may be a novel therapeutic strategy for reducing inflammation and retarding the progression of atherosclerosis and possibly lowering mortality in our peritoneal dialysis patients.
This study is design to compare two different strategies aiming to lessen the degree of the ongoing process of allograft injury either by removing tacrolimus from the maintenance immunosuppressive protocol or by reducing tacrolimus dose. The primary goal is to assess the change in renal function at 6 and 12 months after conversion using creatinine levels and calculated creatinine clearance. The study will include two groups: The study group of 30 patients and a matched control group with creatinine levels at similar range.
The purpose of this study is to address the pharmacokinetic (PK) profiles of everolimus and tacrolimus in combination in de novo kidney transplant recipients, comparing 1.5 and 3 mg per day of everolimus in fixed doses. For comparison purposes, pharmacokinetic profiles will be performed at first dose (abbreviated), 4th day, 14th day, and 42nd day post-transplantation.
The purpose of this study is to find substances in the blood and urine that indicate that a person has kidney damage. It will identify proteins found only in patients with acute kidney failure but not in normal healthy people or in patients with volume depletion. Adults and children who are at least 3 years old who fall into one of the following four categories may be eligible for this study: 1. Are healthy and have normal kidney function 2. Have volume depletion (this condition differs from acute kidney failure in that it is easily treated with fluids) 3. Are at high risk of kidney failure 4. Have acute kidney failure (kidney shutdown) All study participants will have a history and physical examination. Up to four blood samples of 3 tablespoons each will be taken for laboratory analysis. Urine will be collected for analysis and to measure urine output. The participants length of stay in the study varies. People with normal kidney function will be in the study for 1 day and patients with volume depletion will be studied 3 days. The length of hospitalization of patients at high risk of kidney failure or in acute kidney failure will depend on the patient s condition and medication requirements. The results of this study may lead to the development of earlier and more accurate methods for diagnosing acute kidney failure. With earlier detection, treatment could be started earlier, possibly preventing further damage and helping recovery of injury that has already occurred.
This protocol seeks to define aspects of intestinal and hepatic uptake and metabolism of several amino acids. The major hypothesis to be tested is that the splanchic bed (intestine and liver) conserves essential amino acids and metabolites while synthesizing and metabolizing nonessential amino acids. The aims of the study include defining the relative roles of enteral and hepatic extraction/metabolism in the disposition of glutamate, alanine, methionine and other amino acids. Emphasis will also be placed on studies of the transamination of alpha-ketoisocaproic acid (KIC) to leucine since this reaction is of potential importance in the design of nutritional regimens for patients with renal disease.
Kidney diseases related to the immune system include, nephrotic syndrome, glomerulonephritis, membranous nephropathy, lupus nephritis, and nephritis associated with connective tissue disorders. This study will allow researchers to admit and follow patients suffering from autoimmune diseases of the kidney. It will attempt to provide information about the causes and specific abnormalities associated with autoimmune kidney disease. Patients with kidney disease as a result of their immune system, and patients with diseases of the immune system who may later develop kidney disease, will be potential subjects for this study. Patients will undergo a history and physical examination, and standard laboratory test to more closely understand the causes, signs, symptoms, and responses to medication of these diseases. Based on these evaluations the patients may qualify as candidates for other experimental studies. At any time these patients may be asked to submit blood or urine samples for further research.
