Filter by:The purpose of this study was to evaluate the long term safety and tolerability of peginesatide for the maintenance of hemoglobin in participants with chronic kidney disease (CKD) who had received at least 24 weeks of peginesatide treatment in an earlier study.
The purpose of this study was to determine the dose ranges of peginesatide administered intravenously or subcutaneously that maintained hemoglobin in participants on dialysis whose hemoglobin values were stable on epoetin (alfa or beta).
Patients treated by chronic renal replacement therapy are exposed to cardiovascular problems and suffer from an accelerated and sever atherosclerosis. Classical risk factors for atherosclerosis and cardiovascular diseases (CVD) do not explain the full risk of CVD in the dialysis patients. Additional risk factors are therefore likely to exist. The uremic syndrome is attributed to the progressive retention of a large number of compounds, which under normal conditions are excreted by the healthy kidneys. Uremic toxins such are parathormone (PTH), vitamin D and phosphates, cause development of renal osteodystrophy (ROD), i.e. disordered calcium and phosphate metabolism. Both conditions of hyperparathyroid and adynamic bone disease (ABD) lead to an elevated calcium x phosphate product and increased vascular calcification, which might occur in intimal and medial layer of the vessel wall. It is important to consider these processes separately, as the vascular consequences (occlusion with atheromatosis and vascular stiffening through medial calcification) are different. Moreover, the difference between uremic and non-uremic intimal plaque is not the size but its composition, with markedly increased calcium content. Hence, these observations have an important socio-economic impact because of the increased cardiovascular morbidity and mortality. The investigators hypothesized that uremic toxins in dialysis patients influence directly and/or indirectly the development of atherosclerosis, vascular calcifications and CVD.
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
The purpose of this study was to evaluate the long term safety and tolerability of peginesatide for the maintenance of hemoglobin in participants with chronic kidney disease (CKD) who had received at least 24 weeks of peginesatide treatment in an earlier study.
1. Cardiovascular risk is high in patients with renal failure. 2. Cross-sectional studies have indicated a relationship between arterial stiffness and renal function. However, there are no prospective longitudinal studies in the literature. 3. In dialysis patients, arterial stiffness as well as wave reflections, predict mortality. However, there are no data on patients with mild-to-moderate renal impairment available. 4. Therefore, we designed a study to test the hypothesis that: a) measures of arterial stiffness and wave reflections predict the progression of renal impairment in patients with mild-to-moderate renal failure; and b) measures of arterial stiffness and wave reflections predict cardiovascular events in patients with mild-to-moderate renal failure
The purpose of the study is to evaluate the effectiveness, safety and clinical outcome of Epoetin alfa with dosing regime in accordance with Summary of Product Characteristics in the treatment of anemia in predialysis.
Patients will be treated with hemodiafiltration (HDF) in postdilution mode, as a control therapy, during 9 weeks. During week 5 the 1st intervention treatment, predilution hemofiltration (HF) or predilution HDF, will be performed as a midweek session. After 4 additional weeks of control therapy the other intervention treatment will be performed. Samples will be taken during week 4, 5 and 9: from inlet blood flow (0, 30, 60, 120 and 240 min), from outlet blood flow and dialysate outflow (30, 60, 120 and 240 min).
Homocysteine recently gained access to the category of risk factor for the development of atherosclerotic cardiovascular disease in the general population. Chronic renal failure patients, even before being introduced to dialysis therapy have almost universal elevation of serum homocysteine; when on dialysis their mortality is above 50% related to cardiovascular disease that we might now speculate, with a contribution of potentially toxic levels of the aminoacid homocysteine.
The purpose of this study is to evaluate the ability of peginesatide (AF37702) to increase and maintain increased hemoglobin levels in participants with chronic kidney disease (CKD) (either not on dialysis, receiving regular hemodialysis or peritoneal dialysis, or following renal transplant) with confirmed antibody-mediated pure red cell aplasia (PRCA).
