Filter by:The relationship between elevated phosphorus levels and morbidity and mortality in patients with chronic kidney disease (CKD) is well recognized, and dietary phosphorus restriction is a mainstay of phosphate management. Current study is an effort to test the effect of a web-based nutritional educational intervention, Kidney School(KS), to improve phosphorous knowledge and control phosphorous intake in CKD patients.
The Infectious Disease Society of America has recently recommended that patients with Human Immunodeficiency Virus (HIV) be screened for kidney disease on a regular basis. Screening involves non-invasive urine and blood test and a screening program has already been initiated here in the University of Mississippi HIV clinic. This study looks at the effect of this new screening program. Our Hypothesis is that screening for kidney disease is a cost effective and important addition to the care of patients with HIV.
The purpose of this study is to demonstrate that Iodixanol 320 is associated with a lower incidence of contrast-induced nephropathy (CIN) when compared with hyperosmolar contrast medium Iomeprol 350 in patients with impaired renal function undergoing percutaneous coronary interventions (PCI).
Recently, growing body of evidence support the finding that anemia frequently occurs in patients with chronic heart failure (CHF). Chronic kidney disease (CKD), as well, is highly prevalent among heart failure patients, and both anemia and CKD are independently associated with increased mortality. A vicious circle is established with CHF causing both chronic renal insufficiency and anemia, and CKD further aggravating anemia which, in turn, worsens CHF and so on. Treatment of the anemia breaks this circle and improves the quality of life, cardiac and renal functions in patients with severe CHF. Intravenous iron alone was proved to allow the maintenance of target hematocrit in one-third of chronic renal failure predialysis patients. Based on these considerations, intravenous iron for anemia in patients with CHF and moderate CKD would represent a reasonable therapeutic approach. The aim of the trial is to assess the efficiency of intravenous iron therapy in the management of mild to moderate anemia associated with CHF NYHA III class and concomitant moderate CKD.
The ATIC study is a randomised, double- blind, placebo-controlled trial in which the effects of oxidative stress-lowering treatment on vascular function and structure are studied in patients with chronic non-diabetic renal failure who are free from manifest arterial occlusive disease. Participants in the trial were randomised to active treatment consisting of add-on therapy with pravastatin, vitamin E and homocysteine-lowering therapy, or to placebo. Subjects not using angiotensin converting enzyme inhibitors (ACE-inhibitors) or angiotensin receptor blockers (ARBs) at inclusion were put on ACE-inhibitors for at least two weeks before the baseline measurement and randomisation. Those who were on ARBs continued their ARBs. We excluded individuals with diabetes mellitus (ADA criteria), active vasculitis, nephrotic syndrome (>3gr/24hr urine protein), renal transplantation, fasting total cholesterol > 7 mmol/L, cholesterol-lowering therapy within three months prior to inclusion or known ischemic cardiac, cerebrovascular or peripheral arterial disease. Ninety-three patients (out of 118 eligible patients) took part in the study and written informed consent was obtained from all participants.
Prevention of progressive renal disease needs a clear understanding of prevalence of early stage of chronic kidney disease in a community. Even in developed countries most subjects in early stages of chronic kidney disease go largely undiagnosed and untreated. Targeted screening could identify a greater numbers of individuals at risk then a general public screening (11). It is economically more feasible to perform in a country like Pakistan. Hypertension and diabetes are highly prevalent in South-Asia.It is anticipated that if target screening of hypertensive population is performed especially of an age group in which intervention might be expected to have maximal benefit it will not only help to identify from a large number of patients with essential hypertension destined to develop or in the course of advancing towards end stage renal disease but will also unearth mislabeled “essential hypertension” that have underlying primary renal disease. This later group may belong to socio-economic disadvantaged population who have limited access to health care and have never been investigated properly. The aim of the Study is to detect sub-clinical chronic kidney disease in hypertensive patients at community level and to identify associated risk factors.
The purpose of the study is to create a Nephrology Tissue Biobank enabling the study of kidney disease from the perspectives of epidemiology, genetics and molecular biology.
The purpose of this study is to evaluate whether cinacalcet + low dose vitamin D attenuates the progression of vascular calcification over one year, compared with a treatment regimen that includes flexible vitamin D dosing in the absence of cinacalcet, in subjects with chronic kidney disease receiving hemodialysis
Although ionizing radiations have been proposed for the prevention of intimal hyperplasia in coronary and peripheral arteries, information is lacking on how irradiation may prevent neointimal smooth-muscle cell proliferation and restenosis on prosthetic haemodialysis vascular access. We will assess the preventive effect of one dose of radiations (14 Gy) administered transcutaneously one day after dilatation of stenosis on prosthetic haemodialysis vascular access in a randomized controlled trial with a standardized clinical and ultrasonographic one-year follow-up.
Patients with chronic kidney disease (CKD) and those with end-stage renal disease (ESRD) undergoing renal replacement therapies show elevated serum phosphate levels which predispose them to cardiovascular calcifications and high risks of death from cardiovascular diseases. However, in certain patients hyperphosphatemia is not related to dialysis insufficiency, excessive daily dietary phosphorus intake or high serum parathyroid hormone (PTH) levels, suggesting that other mechanisms could be involved. Transgenic mice lacking the klotho gene showed a phenotype which resembles that of dialyzed ESRD patients, in the sense that they have hyperphosphatemia, vascular calcifications, and a short lifespan. This study will analyze whether functional polymorphisms or variants in the human klotho gene are associated with hyperphosphatemia in these patients.
