Filter by:Many patients with chronic renal disease show a loss of the nocturnal decline of blood pressure (non-dipper). However, the mechanism is not yet fully understood. We evaluate 24-hour blood pressure in patients with chronic renal disease using an ambulatory blood pressure monitoring device (A & D TM2425). We also analyze the power spectrum of heart rate variability as an index of autonomic cardiovascular modulation using the same device.
Few studies have reported the effect of alpha1-adrenergic antagonists on 24-h blood pressure and regulation of sympathetic nervous activity in hypertensive patients with diabetic nephropathy. Using ambulatory blood pressure monitoring devices equipped with spectral analysis of heart rate variability, we assess the effects of doxazosin on blood pressure in diabetic nephropathy patients and compare the results with those in patients with essential hypertension, patients with diabetes mellitus and patients with chronic nephropathy.
We sought to determine if there is a benefit to using an insulin drip to control hyperglycemia in the surgical critical care unit for patients who undergo general and vascular surgery.
The purpose of this study is to see if rosuvastatin helps to reduce the number of heart attacks, strokes and cardiovascular deaths in patients undergoing haemodialysis.
Acute kidney failure is common in children in the Pediatric Intensive Care Unit (PICU). You are being asked to participate in this study because your child is being treated for kidney failure with continuous veno-venous hemofiltration (CVVH). CVVH is a continuous, gentle form of removing excess fluids and small wastes from the blood, similar to kidney dialysis (artificial kidney). It is an accepted therapy for temporary support of kidney failure. In some patients with acute kidney failure, beginning CVVH is followed by a temporary decrease of urine output. The reason why this happens is currently unknown. The purpose of this study is to determine why this happens.
Based on theories regarding decision-making and patient education the investigators have developed Patient-Centered Advance Care Planning (PC-ACP). This intervention is designed to improve patient and surrogate knowledge of ACP, increase the congruence between patient and surrogate in treatment decisions, decrease the patient's and surrogate's conflict in making such decisions, and increase the consistency between patient preferences and the actual care they receive. The ACP intervention is conducted with the patient in the presence of the surrogate.
Valganciclovir (VGCV) has recently been approved by the Food and Drug Administration (FDA) for the treatment and prevention of cytomegalovirus (CMV) retinitis in HIV patients. It is under review for the prevention of CMV disease following organ transplantation. Mycophenolate mofetil (MMF), the morpholinoethyl ester of mycophenolic acid (MPA) is currently the most widespread used immunosuppressant in kidney transplantation. These drugs exerts their effects by blocking the production of DNA primarily in lymphocytes. Recent studies have suggested that combining both MMF and GCV in vitro may have a beneficial effect on the treatment of CMV infections. However, the effect of these two drugs in combination on the effects of the immune system both in vitro and in vivo have not been studied. Preliminary studies in our lab show that a combination of these two drugs have an additive effect on the level of immunosuppression of both the growth and differentiation of progenitor bone marrow cells as well as lymphocyte proliferation. This study is designed to test patients degree of immune reactivity both on and off VGCV when used in combination with MMF. Patients will have blood drawn as several time points and an immune assay will be performed to show if VGCV when used in combination with MMF exerts immunosuppressive effects.
Sleep disorders are common in patients with end-stage renal disease on both hemodialysis and peritoneal dialysis and are associated with significant medical, psychological and social disturbances. Numerous factors have been suggested as contributing to or associated with the high prevalence of sleep disturbance in this population. Increasing evidence suggests that cytokines are involved in the regulation of sleep and wakefulness and that the communication between the sleep and the immune system is bi-directional. Blood-dialyzer or peritoneum-dialysate interaction during dialysis therapy has the potential to activate mononuclear cells leading to production of inflammatory cytokines. These cytokines are believed to play a significant role in dialysis-associated morbidity and mortality. Nevertheless, a cytokine overproduction may alter sleep pattern in chronic dialyzed patients, thus explaining the presence of sleep disorders in these patients. In the other way, sleep loss may have effects on immune process and secretion of cytokines in chronic dialyzed patients. The purpose of this study was to examine the relationship between quality of sleep and serum cytokine levels in hemodialysis and peritoneal dialysis patients.
The purpose of this study is to demonstrate the safety and effectiveness of Hectorol® (doxercalciferol) capsules in treating patients with Stage 3 or Stage 4 chronic kidney disease (CKD) with secondary hyperparathyroidism who have vitamin D levels in the normal range. Previous studies with doxercalciferol were conducted in patients who had low levels of vitamin D.
Clinical Problem: Renal insufficiency after heart transplantation caused by cyclosporine medication was addressed. Current therapeutic approaches include cyclosporine reduction or discontinuation. It is unclear whether discontinuation of low dose cyclosporine also has a beneficial effect, i.e. is there a threshold effect for cyclosporine nephrotoxicity? Study Design: Heart transplant patients with a moderate degree of renal failure on low dose cyclosporine were randomized to either a) no change; or b) discontinuation of cyclosporine and initiation of rapamycin immunosuppression. Read-Out: Renal function after 6 months; tolerability; and safety were assessed.
