Uremic patients have an increased incidence of cardiovascular disease (CVD), endothelial dysfunction and oxidative stress that can contribute to cardiovascular (CV) events. To assess the relationship between endothelial dysfunction, oxidative stress and renal failure severity, we studied 40 patients (age 57 +/- 7 yrs, 24 males) affected by chronic kidney(More)
BACKGROUND Elderly transplant candidates represent an increasingly important group on the waiting list for kidney transplantation. Yet the factors that determine posttransplantation outcomes in this population remain poorly defined. METHODS We performed a population-based retrospective cohort study involving all patients aged 60 years or older who(More)
OBJECTIVES We sought to evaluate whether fasting hyperhomocystinemia reduces endothelial function by oxidative stress in normotensive subjects and hypertensive patients. BACKGROUND Subjects with hyperhomocystinemia have endothelial dysfunction. METHODS In 23 normotensive subjects and 28 hypertensive patients, classified into normohomocystinemic and(More)
PURPOSE To better communicate the impact of poor persistence when preventive therapies are initiated, we propose a new measure that is intuitively understandable for clinicians. This measure is the percent wasted patients (PWP). METHODS The PWP is the percentage of patients, out of the new users of a given preventive treatment, who have discontinued(More)
BACKGROUND Acute kidney injury (AKI) is a clinically important condition that has attracted a great deal of interest from the biomedical research community. However, acute kidney injury AKI research findings have yet to be translated into significant changes in clinical practice. OBJECTIVE This article reviews many of the preclinical innovations in acute(More)
BACKGROUND AND OBJECTIVES Prior reports have suggested that patients with impaired renal function receive less aggressive care after an acute coronary syndrome (ACS). The aim of this study was to determine whether this held true in a contemporary cohort, after thorough adjustment for cotreatments/comorbidities. DESIGN, SETTING, PARTICIPANTS, &(More)
BACKGROUND Uraemia is associated with endothelial dysfunction, but the effect of uraemic plasma on the gene expression pattern of human coronary arterial endothelial cells (HCAEC) has never been defined. METHODS HCAECs were exposed for 48 h to a culture medium supplemented with 20% uraemic vs normal plasma. We extracted mRNA and hybridized it onto(More)
BACKGROUND Commercial intact parathyroid hormone (I-PTH) assays detect molecular form(s) of human PTH, non-(1-84) PTH, different from the 84-amino acid native molecule. These molecular form(s) accumulate in hemodialyzed patients. We investigated the importance of non-(1-84) PTH in the interpretation of the increased I-PTH in progressive renal failure. (More)
INTRODUCTION Delayed graft function (DGF), defined as the need for dialysis during the first week after renal transplantation, is an important adverse clinical outcome. A previous model relied on 16 variables to quantify the risk of DGF, thereby undermining its clinical usefulness. We explored the possibility of developing a simpler, equally accurate and(More)
There is no guideline regarding the concomitant or distant administration of sevelamer and calcium carbonate. Our aim was to determine whether serum phosphate varied when sevelamer and calcium carbonate were administered concomitantly in comparison to administration at separate meals. Fourteen chronic hemodialysis patients were enrolled in this cross-over,(More)
