Filter by:The long-term goal is to assess the fall in kidney function measured by glomerular filtration rate (GFR) when patients with chronic kidney disease (CKD) are exposed to intravenous iron (IVIR). We hypothesize that in subjects with mild to moderate CKD, infusion of intravenous iron (IVIR), will generate oxidative stress and cause an inflammatory response that will be associated with a more rapid decline in glomerular filtration rate (GFR) compared to oral iron.
This study will follow 2500 prevalent Chronic Kidney Disease (CKD) patients with Glomerular Filtration Rate (GFR) from 15-45 ml/min for 30 months with serial measurements every 6 months and subsequent annual chart review up to 60 months. This observational study will analyze the demographics, clinical status, medications and blood and urine samples of these patients and study the conventional biochemical, hormonal and metabolic parameters assessing which underlying biomarkers reflect the processes involved with disease progression.

Patients with chronic kidney disease (CKD) have higher blood pressures than the general population. They also tend to have protein leaking into the urine (proteinuria). CKD, high blood pressure and proteinuria independently and together increase the risk of developing atherosclerosis (hardening) of the arteries that leads to diseases such as heart attack and stroke. Although there are a number of drugs available that lower blood pressure, these are not always fully effective. Furthermore, there are even fewer drugs that simultaneously lower blood pressure, reduce proteinuria, and slow down kidney damage in CKD. Recent research has shown that drugs like sitaxsentan not only lower blood pressure but also reduce proteinuria and potentially slow down the progression of CKD [1,2]. Before sitaxsentan can become freely available to individuals with CKD it is important to look at the effects this drug could have on proteinuria and blood pressure. 1.

The prevalence and mortality rate of cardiovascular disease (CVD) in chronic kidney disease (CKD) patients is high. The prevalence of coronary artery disease (CAD) in CKD population ranges from 38 to 65%, with an average of 3.3 coronary lesions per person. The relative risk for death from myocardial infarction and CAD is 1.18 in CKD patients with GFR < 60 ml/min. Because of this high prevalence of CAD and its high mortality, reducing and preventing CAD risk factors is crucial in the clinical management of CKD patients. Low glomerular filtration rate (GFR) constitutes an important independent risk factor for CAD. Several pathogenic factors play role in the genesis of cardiovascular dysfunction in chronic kidney disease. Increased traditional CAD risk factor, endothelial dysfunction, sympathetic hyperactivity, renin-angiotensin system activation, increased glycosylated end products, all contribute to the characteristic medial calcification of cardiovascular disease in CKD patients. Hypertension, fluid overloading and anemia further aggravated the cardiac loading, leading to myocardial hypertrophy with chamber dilatation, heart failure and death. The mortality rate of CAD in CKD patients is extremely high. The NHANES II (National Health and Nutritional Evaluation Survey) found an increased of mortality rate> 51%, when the GFR decreased from > 90 to < 70 ml/min. The 1-year mortality rate in different CKD stage were 0.7% (normal renal function patients), 2.0% (patients with proteinuria), 3.5% (overt proteinuric patients) and 12.1% (dialysis patients), respectively. However, the clinical feature and outcome of CAD in different stage of CKD remains unclear. We conducted a retrospective cohort study involving all patients admitted for coronary angiography from 1992 to 2004. The patients were categorized into five stages of CAD to compare the risk factor, clinical feature and outcome. Determination of this relationship can help to establish factors for early detection of CAD in CKD patients and also prognostic factor to improve outcome of these patients.
The Division of Kidney, Urologic, and Hematologic Diseases (DKUHD) of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), in collaboration with the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and the National Heart, Lung and Blood Institute (NHLBI) funded a cooperative agreement including two Clinical Coordinating Centers (at Children's Hospital of Philadelphia and at Children's Mercy Hospital in Kansas City), a central biochemistry laboratory (at the University of Rochester) and a Data Coordinating Center (at Johns Hopkins School of Public Health) to conduct a prospective epidemiological study of children with chronic kidney disease (CKD).
In type 2 diabetics, progression from chronic kidney disease to end stage renal disease may be slowed down by therapeutic interventions as angiotensin converting enzyme inhibitors use, control of high blood pressure and proteinuria, control of hyperglycaemia, protein intake restriction, smoking cessation. Correcting anaemia in these patients may prevent impairment of renal function. International guidelines indicate that haemoglobin level has to be of 110 g/L in these patients. We conduct an interventional randomized trial to evaluate the potential benefit of an haemoglobin level of 130 g/L in patients with type 2 diabetes and with a chronic kidney disease defined by a Cockcroft's creatinine clearance of 25 - 60 ml/min.
The purpose of this study is to establish the long-term safety and efficacy of Biogeneric Epoetin, the attainability of therapeutic target for anaemia management, and the impact of Epoetin treatment on long-term health outcome and its cost effectiveness.
Patients with Chronic Kidney Disease (CKD) have been shown to have high coronary calcium scores (CAC), but the temporal association between Glomerular Filtration Rate, CVD risk factors and CAC has not been described. This is a single-center, longitudinal, observational study. Subjects included adults aged 18 years to 65 years old without preexisting coronary artery disease (CAD). The CKD subjects (GFR < 60 ml/min) and the control subjects (GFR >/=60ml/min) were recruited. Laboratory measurements and MDCT scan were performed at baseline and after 12 months. Baseline CAC and average intact parathyroid hormone (iPTH) level were significantly greater in the CKD group. Baseline CAC scores of the CKD group were twice the value of the control group; however, CAC scores over one year were unchanged from baseline.
