Prasugrel Versus High Dose Clopidogrel in Clopidogrel Resistant Patients Undergoing Chronic Hemodialysis...
HemodialysisChronic Renal FailureClopidogrel administration is essential in patients undergoing percutaneous coronary intervention, in patients with previous stroke, in patients under chronic hemodialysis via fistulae and in patients with chronic atrial fibrillation if coumarin administration is not a viable option. Patients with chronic renal failure present lower clopidogrel response compared to those with normal renal function. Additionally, hemodialysis via the dialysis filter causes a decrease in glycoprotein platelet receptors, potentially associated with thienopyridine hyporesponsiveness. Clopidogrel resistant patients as assessed by VerifyNow P2Y12(Accumetrics)will be randomized in 1:1 fashion to prasugrel 10mg/day or clopidogrel 150mg/day. On day 15±2 days a crossover directly to the alternate treatment group will be carried out, without an interventing washout period. All patients will undergo platelet reactivity assessment, documentation of major adverse cardiac events and documentation of any serious adverse events(stroke, bleeding)at day 15 and day 30.

Combined Kidney and Bone Marrow Transplantation to Prevent Kidney Transplant Rejection
Kidney TransplantationKidney Failure1 moreIn small initial studies, combined kidney and bone marrow transplants from the same donor have permitted some individuals to stop taking anti-rejection medicines without rejecting their transplant. This clinical trial will study this method in a greater number of people to determine if it is indeed effective and safe.
Conventional Hemodialysis vs. Short Daily Hemodialysis (6 Days / Week) and Mechanisms of Blood Pressure...
End Stage Renal DiseaseMore than 80% of patients with end stage renal disease have hypertension; 70% of whom are poorly controlled using conventional Hemodialysis therapy. An expanded extracellular fluid volume and an increase in peripheral vascular resistance as a result of hemodynamic/trophic effects of an increased sympathetic nerve activity, angiotensin II, asymmetrical dimethyl arginine, and decreased nitric oxide are the most frequently quoted mechanisms contributing to hypertension in this population. The intermittent nature of conventional hemodialysis treatments (4 hours, 3 days/week) results in the majority of patients having a sustained expansion of the extracellular fluid volume that likely contributes to the activation of neurohormonal pathways. However, daily therapy including short daily hemodialysis (2 hours, 6 days/week) and nocturnal hemodialysis (6-8 hours, 5-6 days/week) improve or even normalize blood pressure. Short daily hemodialysis appears to improve blood pressure secondary to a reduction in extracellular fluid volume (7,8) whereas the improvement in blood pressure with nocturnal hemodialysis occurs by a reduction in peripheral vascular resistance (8,9,10). This is consistent with the Katzarski et al experience (7-8 hours, 3 days/week) and one randomized controlled trial in which blood pressure control was due to normalization of extracellular fluid volume in some patients and a reduction in peripheral vascular resistance in others. The majority of the studies in daily dialysis are observational, do not include a run-in period to optimize blood pressure management and have not explored the mechanisms of improvement in blood pressure in detail. We have designed a 9 month study to determine if the mechanism by which short daily hemodialysis is associated with an improvement in blood pressure control is secondary to changes in sympathetic nervous system activity and/ or extracellular fluid volume. Additionally we would like to explore the potential impact of short daily dialysis, compared to conventional dialysis, on markers of inflammation and oxidative stress in detail.
Removal of Uremic Toxins With Nocturnal Dialysis Versus Standard Dialysis
Chronic Renal FailureDialysis patients, who decide to switch from standard dialysis (3 times 240-270 min/week) to nocturnal dialysis (3 times 480 min/week), will be followed. In parallel a control group with patients staying on standard dialysis will be followed. The study will last 30 weeks. During this period blood samples (pre- and post-dialysis: 10 times; inlet and outlet of dialyzer: 3 times) will be collected on predetermined time points. Concentration of several uremic retention solutes will be determined.
