Filter by:A central goal of this data repository is to collect data from a large population of subjects with a variety of renal disease states. Cohorts will include subjects with diabetes, inflammatory/autoimmune and transplant related renal conditions. Additionally, the repository will have the capacity to store biospecimens and electronic data in control subjects without established renal disease. This initiative will provide an opportunity to compare data from various disease states and controls with the objective of determining clinical and biological factors that predict disease progression, response to therapy and identify discriminating noninvasive clinical and biological features that predict renal biopsy findings.
Chronic allograft injury is the leading cause of graft loss in renal transplantation. The shortage of available kidneys for transplantation has reached crisis levels with increasing numbers of waiting list mortalities. Strategies to prolong graft survival are urgently needed. The pediatric and young adult transplant population is one in which repeat transplantation is inevitable and therefore, this group is one who will especially benefit from intervention to prolong graft survival. The hypothesis of this proposal is that subclinical viral infection is a modifiable risk factor in the pathogenesis of chronic allograft injury. The young age of the proposed study population is an ideal one to evaluate this objective due to the high prevalence of seronegative recipients. The studies outlined will determine the temporal relationship betWeween subclinical viremia, renal allograft infection and allograft injury. This will be the first prospective study in renal transplant recipients to systematically monitor subclinical viral infection both in peripheral blood and in the renal allograft with concurrent quantitative measures of renal function, allograft fibrosis, and innate immune activation. The investigators have chosen these 3 outcomes because they evaluate a spectrum of renal allograft injury and represent different stages - from early to late - in the pathophysiology that leads to renal allograft dysfunction. In addition, the role of virus specific T cell immune responses in the control of subclinical viral infection and associated allograft injury will be determined. These data are critical as they will provide insights into the pathogenesis of injury and will guide development of interventions strategies. Importantly, the current treatment strategies for viral disease do not prevent subclinical viral infection. Thus, the results of this study may identify that prevention, prophylaxis and/or treatment of subclinical viral replication as a long term strategy to prevent chronic allograft injury and prolong graft survival.
The purpose of this study is to compare renal toxicity of Iodixanol and Iopromide in patients with renal dysfunction.
It is hypothesized that a consistent use of the Hemocontrol TM biofeedback function improves long-term cardiovascular outcome, mediated by reduced hypertension due to fluid overload and by reduced incidence of intradialytic hypotensive episodes
T regulatory cells (T regs) are responsible for immune tolerance in solid organ transplant patients. This study will evaluate the treatment of children with kidney transplants either with Campath and other immune system suppressing medications alone or in combination with injection of autologous CD4+CD25+CD127lowFoxP3+ T regulatory cells expanded ex vivo. The aim of this study is to develop a new strategy that will be more effective in preventing organ rejection and maintaining patient health.
The purpose of this study is to determine the value the additional antiproteinuric effects of vitamin D derivatives treatment, in patients with Chronic Kidney Illness phase II-IV, with lack of vitamin D and residual proteinuria higher 0,5 grams/day.
This study aims to maintain a prospective biobank of human samples obtained from donors and recipients of renal allografts, including biopsy tissue, peripheral blood samples and urine samples.
Treatment with n-acetylcysteine in patients with heart failure and chronic renal failure leads to improvements in vascular function and in renal function.
The purpose of this study is to determine whether sodium bicarbonate is effective in reducing kidney injury that may occur during cardiac surgery.
This prospective, randomized study, comparing sirolimus to cyclosporine in renal transplant recipients, has two major objectives: 1. -To determine the incidence and the degree of interstitialfibrosis and arteriosclerosis, as wel as the glomerular volume in protocol biopsies at 6 months in sirolimus-and in cyclosporine-treated renal allograft recipients, by means of quantitative computerized image analysis. - To determine the prognostic implication of these morphologic changes. 2. To study the expression of genes, involved in inflammation and fibrosis, in protocol biopsies at 6 months in sirolimus-and cyclosporine-treated renal allograft recipients.
