Bupropion for Depression in ESRD Patients on Hemodialysis
Major DepressionEnd Stage Renal DiseaseThe proposed study will evaluate the response and remission rates for major depressive disorder (MDD) in end-stage renal disease (ESRD) patients undergoing maintenance hemodialysis (HD) treated with bupropion or fluoxetine for 12 weeks. In addition, the study will document the relative tolerability and safety, and longitudinally contrast the effects of bupropion and fluoxetine on measures of cognitive function, fatigue, inflammation, and tryptophan (TRP) and TRP catabolites in blood. It is hypothesized that both drugs will significantly reduce MDD symptoms from baseline, and be tolerable and safe, but bupropion will be associated with greater reduction in pro-inflammatory cytokines, cognitive impairment, and fatigue compared with fluoxetine. The Specific Aims of this study are: Aim 1: Determine the efficacy of bupropion and fluoxetine in treatment of MDD in ESRD/HD patients. Aim 2: Determine whether longitudinal change in MDD symptoms, cognitive dysfunction, and fatigue differ between bupropion and fluoxetine. Aim 3: Determine whether longitudinal change in MDD symptoms, cognitive dysfunction, and fatigue correlate with change in inflammation, measures of TRP availability to brain, or neurotoxic TRP metabolites. Hypotheses: Bupropion and fluoxetine will both show efficacy in treating MDD; Bupropion will lead to greater improvement in cognitive dysfunction and fatigue than fluoxetine; and Change in cognition and fatigue over time will correlate with change in c-reactive protein (CRP) and quinolinic acid and change in overall depression score will correlate with measures of TRP availability.
Using Sitagliptin as a Treatment to Prevent New Onset Diabetes After Kidney Transplantation
Type 2 DiabetesEnd Stage Renal DiseaseThis study is designed to see if the use of the drug Sitagliptin (used to reduce insulin resistance) will delay or prevent kidney transplant patients from getting diabetes.
Safety Study of the Vascular Wrap Paclitaxel-Eluting Mesh for Hemodialysis Vascular Access
End Stage Renal Failure on DialysisHyperplasiaThe purpose of this study is to determine whether the long term use of the experimental Vascular Wrap(TM) Paclitaxel-Eluting Mesh is safe in the treatment of subjects needing hemodialysis access (via an expanded polytetrafluoroethylene (ePTFE) graft).
The Effect of Nighttime Dialysis on the Inflammation of Kidney Failure
End-Stage Renal DiseaseThis study will determine whether a new form of home hemodialysis carried out at night during sleep reduces blood levels of hormone-like substances called cytokines that may cause fatigue and increase blood fats and sugar. Participants will stay twice in the Rockefeller Hospital and receive a standard diet and blood testing. Training for nocturnal hemodialysis will be provided at the nearby Manhattan Dialysis Center of The Rogosin Institute, affiliated with The Rockefeller University.
Study of the Use of Niaspan for Treatment of Dyslipidemia in Diabetic Nephropathy
Diabetes MellitusType 23 moreThe primary purpose of this study is to test the effectiveness and tolerability of Niaspan® to improve the levels of blood fats ("good" and "bad" cholesterol and triglyceride levels) in people who have kidney damage due to diabetes. A secondary goal is to test whether Niaspan® slows down further development of kidney damage.
Safety and Efficacy Study of the Effect of Etanercept in Hemodialysis Patients
End Stage Renal DiseaseEtanercept is a novel anti-inflammatory agent currently used in patients with rheumatoid arthritis. We are examining whether Etanercept is effective in improving the nutritional status of hemodialysis patients as a consequence of its ability to decrease inflammation.
Protein Supplementation in Dialysis Patients
End Stage Renal DiseaseThe mortality rate in chronic hemodialysis (CHD) patients remains excessively high and approaches 21% per year. Among the many factors that adversely affects patient outcome is uremic malnutrition, a unique form of deranged nutritional status. It is associated with increased hospitalization and death risk in CHD patients. Several measures have been identified to prevent uremic malnutrition in CHD patients, including efforts to optimize dialysis regimen and dietary protein and energy intake. A large number of CHD patients suffer from uremic malnutrition in spite of these aggressive measures. The inevitable protein catabolic effects of the hemodialysis procedure are important factors leading to increased prevalence of uremic malnutrition. Preliminary data suggest that oral nutritional supplementation administered during the hemodialysis procedure counteracts these protein catabolic effects and leads to net protein anabolism in the acute setting. In this proposal, we hypothesize that Pro-Stat, a high nitrogen, enzyme-hydrolyzed, tryptophan-fortified, collagen protein supplement will reverse the net protein catabolism observed during hemodialysis procedure.
Kidney Function in Sickle Cell Anemia
Sickle Cell DiseaseKidney Failure1 moreThis is a prospective clinical cohort study that involves a baseline study visit followed by up to 3 annual follow-up study visits for a total follow-up of 36-48 months to evaluate the age- and sex-adjusted rate of change in kidney function, and to identify biomarkers of endothelial function, metabolomic profiles and clinical characteristics for the worsening of kidney function and for a rapid decline in kidney function.

The Routine Use of SSRI's at the Initiation of End-stage Renal Disease Treatment (RoSIE)
End Stage Renal DiseaseIn this study the investigators hypothesize that antidepressant therapy may improve the overall welling of patients with acute or chronic kidney disease when given around the time of starting chronic dialysis therapy. This study is a pilot, randomized controlled trial that aims to examine whether prescribing oral escitalopram to all incident dialysis patients is safe and feasible.
Study to Evaluate the Safety of Chronic Administration of Simulect to Subjects Receiving a First...
End Stage Renal DiseaseThe study is undertaken to explore the safety of using Simulect at monthly dose intervals to reduce the need of high dose/level CNI's such as Prograf.
