The serum protein fetuin-A is a potent systemic inhibitor of soft tissue calcification. Fetuin-A is highly effective in the formation and stabilization of protein-mineral colloids, referred to as calciprotein particles (CPPs). These particles ripen in vitro in a two-step process, indicated by a morphological conversion from spheres to larger prolate(More)
BACKGROUND It has been suggested that the incidence of acute pancreatitis in patients with end stage renal failure is increased. AIMS To assess the risk of acute pancreatitis in patients on long term peritoneal dialysis and long term haemodialysis compared with the general population, to evaluate its clinical course and outcome, and to identify possible(More)
Previous reports have suggested the production of complement components C4, C2, and factor B by renal tissue. However, the cells involved in production of complement have not been identified. In this study metabolic labeling experiments demonstrated that human proximal tubular epithelial cells (PTEC) synthesize a 180-kD precursor of C3 that is secreted(More)
BACKGROUND Sleep disturbances have a major influence on quality of life. A commonly used measure of sleep disturbances is sleep efficiency. The purpose of this study was to investigate the prevalence of decreased subjective sleep efficiency in hemodialysis patients. An additional goal was to identify clinical, dialysis or laboratory parameters that are(More)
In 1981 an active programme was started in our centre for living-related kidney donation (LRD). The structure of this LRD programme is described in this paper. Retrospectively the results of this LRD programme were studied. Between 1981 and 1988 139 potential living donors were evaluated. Of all potential donors 47 (34%) actually donated a kidney, including(More)
BACKGROUND AND AIM Acetate free biofiltration (AFB) provides a well-tolerated and efficient renal replacement therapy. Replacement of most of the acetate by bicarbonate in standard hemodialysis has resulted in a decrease in intradialytic hypotensive episodes. This has been attributed to a decrease in the acetate-induced impairment of myocardial(More)
Fifty-nine renal transplant recipients were followed during the first 3 months after transplantation. Once weekly, cultures of urine and buffy coat for CMV were taken. Furthermore, peripheral blood leukocytes were examined by an immunocytochemical assay for immediate early antigens of CMV (IEA assay) and by a polymeric chain reaction for CMV DNA. Forty-four(More)
BACKGROUND Acetate-free biofiltration (AFB) is a haemodiafiltration technique based on continuous post-dilution infusion of a sterile isotonic bicarbonate solution. We performed a long-term randomized prospective trial to compare dialysis efficacy and metabolic control of AFB versus bicarbonate haemodialysis (HD). METHODS The AFB group consisted of 11 and(More)
OBJECTIVE To evaluate the safety, efficacy, and biocompatibility of icodextrin- and glucose-containing dialysis fluid during continuous cycling peritoneal dialysis (CCPD), patients were treated for 2 years with either icodextrin- or glucose-containing dialysis fluid for their daytime dwell (14-15 hours). Prior to entry into the study, all patients used a(More)
Clinically, there is an association between CMV infections and the occurrence of rejection after renal transplantation. Adhesion molecules such as intercellular adhesion molecules (ICAM) and MHC Ags are thought to be important in the induction and amplification of the rejection process. Therefore, we studied ICAM-1 and MHC expression after CMV infection or(More)
