Active clinical trials for "Renal Insufficiency"

Background: - The National Institutes of Health (NIH) performs up to 100 allogenic stem cell transplants (allo-HSCT) each year. Many studies already look at different problems that can follow a transplant. But there are many types of transplants, diseases, responses, and treatments. An organized study of this information could help researchers learn more about how often transplant complications occur and what problems they cause. It could also lead to ideas for future research. This study will focus on complications thought to be the most significant. Objectives: - To gather information on the complications that may occur after an allo-HSCT. Eligibility: - People over 2 years of age currently enrolled in an allo-HSCT study at NIH. Design: Visits for this study will be scheduled along with primary study visits. The number of visits will depend on the primary study schedule. At each visit, participants will answer questions and take physical exams. The same questions and physical exams will continue for as long as they are in the primary study. In between visits, researchers might call participants to discuss their health. They may also discuss the cases with the primary study doctors and other doctors. Primary transplant study doctors will make treatment decisions. When participation in the primary transplant study ends, participation in this study will also end.

The purpose of this study is to measure glomerular filtration rate (GFR) by iohexol plasma disappearance (gold standard) and measure serum Cystatin C levels (surrogate marker) in patients enrolled in our prospective study at baseline, day 100 and 1 year after hematopoietic cell transplant and determine if these levels correlate with serum creatinine and an estimated GFR using the Modification of Diet in Renal Disease (MDRD) equation and Schwartz formula in children.

This is a pilot study to test the utility of an integrated approach in the management of the anemia of chronic kidney disease through the administration of both an erythropoietic stimulating agent and iron. Subjects will be studied for 6 months during which all iron dosing will be recommended using a computer based tool using model predictive control. Comparisons will be made to the 6 months prior to enrollment in to the study.

The purpose of this study is to assess how fast tirzepatide gets into the blood stream and how long it takes the body to remove it in participants with impaired kidney function compared to healthy participants.

Acute renal dysfunction associated with cardiac surgery (DRA-ACC) in our hospital population affects 39% of patients, being an important cause of morbidity and mortality, increasing the need for dialysis and assuming a prolongation of stay in the unit of intensive care, as well as an increase in the economic cost. In this sense, extracorporeal circulation (CPB) is a clear aggression for renal function due to multiple effects, not entirely known. Human albumin is sometimes used as part of the priming of the CEC circuit in variable concentration according to published centers and studies, demonstrating benefits on the maintenance of plasma oncotic pressure during the period of ECC, as well as other effects that can protect renal function during this period of renal injury. Despite the use of albumin in the ECC priming both in Spain and in other countries, there are currently no published studies demonstrating the effect of albumin on renal function administered during CPB in cardiac surgery during the postoperative period. with a high incidence of kidney injury, although there are current studies that confirm a decrease in the incidence of kidney injury in patients with hypoalbuminemia and who undergo heart surgery without extracorporeal circulation. The hypothesis of this study is based on the potential protective effect of albumin on renal function in patients undergoing heart surgery under CPB, in which there is a high incidence of postoperative hypoalbuminemia. This study aims to obtain information about the effect that albumin can have in this population of patients with a high incidence of acute renal dysfunction, and if this benefit exists, whether it is significant or not to justify its systematic use.

INTRODUCTION: Accurate estimation of dry weight (DW) is an important and difficult problem in clinical practice. DW is defined as the lowest weight after hemodialysis (HD) where the patient will not develop symptoms of hypotension and edema, in addition to not using antihypertensives. Achieving a fluid balance benefits the control of blood pressure and reduces cardiovascular risk. In most HD centers, the DW is estimated using a subjective method dependent on the signs and symptoms that the patient presents. Recently, several approaches have been studied to develop a standardized DW evaluation technique. Among these, the analysis of electric bioimpedance vectors (BIVA) has been recognized as a simple and promising method with high reproducibility. OBJECTIVE: To use BIVA to improve dry weight estimation in patients with chronic renal failure undergoing hemodialysis. Methods: This is a non-randomized pre-test / post-test clinical trial, where the universe of patients comes from the hemodialysis unit of the General State Hospital of Sonora. Patients who have limb amputations, pacemakers, metal implants, who are under renal transplant protocol or who have a renal transplant, and presence of infectious foci will be restricted from participating. The diagnosis of DW in the patients will be performed for modification and follow-up. Fluid status will be evaluated using BIVA. Measurements will be made before and after HD in three consecutive weekly periods and one one final assessment at three months. At the beginning of each period, weight, electrolytes, creatinine, total proteins, albumin, pre-albumin, urea and blood pressure will be measured to calculate the Malnutrition Inflammation Score and Bilbrey Index. At the end of the HD protocol of each period, body composition and muscle strength will be evaluated through triceps skinfold, mid-upper arm circumference and dynamometry. The dialysis dose received will be modified according to BIVA. The main variables to be considered will be DW, extracellular water and blood pressure. The duration of the study will be approximately 6 months. In addition, at the end of each measurement, each participant will be given a nutritional recommendation (feeding guide) specific to their energy requirements.

Kidney Disease subjects will be recruited to take part of a mindfulness-based stress reduction intervention for 8-10 sessions. All subjects will complete a baseline interview, one follow-up at 3 months and the close out interview at 5 months.

Allopurinol-induced severe cutaneous adverse reaction (SCAR) is a rare but fatal condition. Previous reports have reported that HLA-B*5801 is an important genetic risk factor significantly associated with the development of allopurinol-induced SCAR. However, there has been no prospective study to prove the clinical efficacy of a HLA-B*5801 screening before administration of allopurinol in predicting allopurinol-induced SCAR. The purpose of this prospective study is to test our hypothesis that a pre-screening of HLA-B*5801 will significantly reduce the risk of allopurinol-induced SCAR development compared to the historical control.

Several epidemiologic studies reported that patients with renal insufficiency might have increased cardiovascular disease-related mortality rates after Percutaneous coronary intervention (PCI) . The increased risk in this population may be related to the less use of standard guideline-based treatment and the resulting inability to perform PCI effectively. Recently, with the technology improvement and the progress in clinical trials, Chinese guidelines have made new recommendations about the patients with acute coronary syndrome(ACS) in different states of renal function. However, scant epidemiologic information exists on the prognosis of those patients, especially in Henan. And there is still some uncertainty whether those patients are using the latest guideline recommended treatment. This multicenter, prospective, observational study is aimed to evaluate the long prognosis in patients with acute coronary syndrome complicated with renal insufficiency, and to analysis its related factors that influence the outcomes.

Despite many efforts to increase the size of the donor pool, there is a large and growing disparity between the number of donor kidneys available for transplantation and the number of patients on the transplant waiting list. Increasing the quality of currently available donor kidneys would potentially improve the longevity of deceased donor kidney transplants by years, thus increasing the rate of transplantation patients on the kidney transplant waiting list. In addition, recipients of higher quality kidneys have shorter hospital stays and lower total hospital charges. By innovating the organ donation process, such that deceased donor kidneys are removed prior to the cessation of cardiac activity, rather than after, it may be possible to improve the quality of the kidney before transplantation, resulting in improved function after transplantation and increased longevity of these transplanted kidneys. Further, this improved kidney quality is highly likely to translate to reduced need for renal dialysis and other high-cost interventions, yielding lower total hospital charges. In this study we will test the hypothesis that, through a cost-free technical innovation, the quality of deceased donor kidneys could be improved significantly, saving thousands more lives per year and reducing total health care expenditures on renal transplantation.
