Filter by:This pilot study of combined kidney and hematopoietic stem cell transplantation attempts to establish a protocol to induce immunological tolerance as a new strategy to prevent renal graft rejection. If successful, this strategy would restore renal function, while avoiding the risks associated with long-term standard anti-rejection therapy, and would represent the first option to cure end-stage renal disease.
Patients with chronic kidney disease (CKD) have a markedly higher prevalence of cardiovascular disease (CVD) than the general population. Dyslipidemia is considered a major cause of CVD in patients with CKD. Especially for peritoneal dialysis (PD) patients, the use of glucose as the osmotic agent in PD solutions has been associated with a variety of metabolic consequences ranging from acute hyperglycemia and hyperinsulinemia to dyslipidemia and weight gain. Among lipid abnormalities, hypertriglyceridemia is the most common in PD patients. A study showed that patients with high triglyceride levels were more insulin-resistant than those with normal triglyceride levels. Insulin resistant is associated with atherogenic response represented high plasma levels of monocyte chemotactic protein-1 in a large cohort of dialysis patients. Therefore, high triglyceride level may play an important role to CV outcome of PD patients. PD solution decreasing triglyceride levels is essential in PD patients. Icodextrin, a starch-derived high molecular weight glucose polymer was found to increase ultrafiltration compared to glucose solutions. Furthermore, a low peritoneal absorption of icodextrin, which is catabolized into maltose, considerably reduces caloric uptake. Therefore, icodextrin may have an additional favorable effect on triglyceride level. There are several studies regarding the effect of icodextrin on triglyceride level in PD patients. However, the outcomes are controversial, some studies showed no association between icodextrin and triglyceride change, even the others showed positive results but these also have study design limitations such as non-randomized study or secondary primary outcome. It is not clear about the effect of icodextrin on triglyceride especially in PD patients without diabetes. The investigators therefore want to conduct a randomized, cross-over, controlled multicenter trial comparing icodextrin solution and glucose solution in PD patients with and without diabetes, focusing on triglyceride change.
To characterize the GORE® Hybrid Vascular Graft as compared to non-heparin bonded synthetic vascular grafts in terms of the prevalence and persistence of anti-platelet factor 4 / heparin antibodies (anti-PF4 / H antibodies).
This project will examine if enhancing Nitric Oxide (NO) bioavailability increases the rates of arteriovenous fistula (AVF) maturation in end stage renal disease patients requiring vascular access for hemodialysis. To enhance NO bioavailability the study team will utilize a program of forearm exercise training, application of nitroglycerin ointment or both. Goals of this study are (A) to measure if recruited subjects can tolerate the intervention protocols, and determine if dependent variable measures, including surgery outcome, and measurement of physiologic and biologic markers, can be obtained; (B) To measure subject compliance and adherence rates for each of the intervention arms and testing visits; (C) To examine which intervention or combination of interventions demonstrates the strongest preliminary effects in order to estimate power for a pivotal intent to treat trial; and (D) explore group differences in clinical vascular markers and biologic markers in vein tissue.
The purpose of this study is to determine the amount of ertapenem in the blood over time between hemodialysis session.
The purpose of this study is to evaluate the impact of 12 weeks of exercise on cognition in patients with end stage renal disease.
Regulatory CD4+CD25+ T cells (Treg) derived from the thymus and/or peripheral tissues have been demonstrated to broadly control T cell reactivity (14). Importantly, Tregs have been shown to control immune responsiveness to alloantigens and significantly contribute to operational tolerance in transplantation models (15, 16). However, there have been limited efforts to harness the therapeutic potential of directly isolated CD4+CD25+ Treg cells for controlling graft rejection and inducing transplantation tolerance, such as for kidney transplants. In order for CD4+CD25+ Treg cells to be used as a clinical treatment, the following cell properties could be necessary: ex vivo generation of sufficient numbers of cells, migration in vivo to sites of antigenic reactivity, ability to suppress rejection in an alloantigen-specific manner, and survival/expansion after infusion for a critical, but currently unknown, period of time. Our published work and that of other investigators has demonstrated 1) the feasibility of expanding Treg ex vivo, 2) the ability of these cells to downregulate allogeneic immune responses in vitro, and 3) the efficacy of Treg for prevention of allograft rejection in animal models (15,16). We have developed strategies for the ex vivo expansion of naturally occurring human Tregs (nTregs) that allow for the practical employment of this cellular therapy in the clinic. Our central hypothesis is that sufficient human nTreg can be expanded ex vivo and used to both prevent renal transplant rejection and facilitate the reduction and subsequent withdrawal of drug-based immunosuppression. This study will allow for us to define the safety of Treg adoptive cellular transfer (TRACT) in living donor renal transplant recipients that draws upon our extensive preclinical experience with expanded Tregs, as well as our recognized clinical expertise with designing immunosuppressive regimens compatible with this type of therapeutic cell transfer.
This is a multi-center, open-label clinical study to assess the single-dose PK of eravacycline in subjects with renal impairment and healthy subjects conducted at approximately 2 sites in the United States. This study includes an up to 21-day Screening Period, a 5-day Treatment Period, and an End of Study Visit occurring approximately 2 weeks (±2 days) after study drug administration. Approximately 12 subjects will be enrolled: 6 subjects with ESRD and 6 healthy subjects with normal renal function. Healthy subjects will be matched to renally impaired subjects in gender, age, and body mass index (BMI). All subjects will be administered a single IV dose of eravacycline (1.5 mg/kg).
The use of C1INH (Berinert) in patients receiving deceased donor kidney transplants with high risk for delayed graft function (DGF) may show significant improvement in outcomes post transplant compared with patients that do not receive C1INH treatment. Complement activation has been detected in animal models and human kidneys with ischemic reperfusion injury (IRI) and inflammatory cell infiltrates. By blocking complement activation the investigators hope to improve kidney graft function post transplant in these recipients.
The time on peritoneal dialysis may be limited for a significant number of patients that use this modality of renal replacement therapy due to the inability of the peritoneal membrane to clear solutes or achieve adequate ultrafiltration, termed peritoneal membrane failure (PMF). This can be devastating for patients who have become accustomed to the quality of life provided by peritoneal dialysis and who otherwise have done well on this therapy. There is clinical evidence suggesting that icodextrin preserves the peritoneal membrane transport characteristics which may be linked to reduced cumulative glucose exposure of the peritoneal mesothelial cells. Theories to explain the role of dextrose in PMF have focused for the most part on the high intracellular concentrations of glucose without consideration to the potential pathogenic role of the glucose transporters which allow glucose entry into the cell. Experimental evidence in non-mesothelial cell lines indicate that some cellular processes that occur under high glucose conditions may not be related to intracellular glucose metabolism but to the type of glucose transporter allowing glucose entry. 3,4 However, little is known about these glucose transporters in peritoneal mesothelial cells and their potential role in the development of PMF. We hypothesize the following - The presence of Sodium Glucose Co-transporter (SGLT1) on peritoneal mesothelial cells plays a role in PMF under hyperglycemic conditions. - Regulation of pro-fibrotic mediators such as reactive oxidative species,transforming growth factor β, and vascular endothelial growth factor are modulated by SGLT1 activation by glucose rather than glucose metabolism or concentration. - Icodextrin does not activate the SGLT1 transporter establishing a mechanism that may explain the beneficial effects of icodextrin on peritoneal membrane transport.
