BACKGROUND The risk of developing cardiovascular diseases is higher in patients on haemodialysis than in the general population. These patients may develop arrhythmias that depend on the extra- and intracellular concentrations of potassium. ECG findings, particularly the QT interval and its dispersion (QT(d)) and the QT(c) (QT interval corrected for heart rate according to Bazett's formula) and...
BACKGROUND Although different on-line convective removal strategies are available, there are no studies comparing the efficiency of solute removal for the three main options [post-dilution haemodiafiltration (post-HDF), pre-dilution haemodiafiltration (pre-HDF) and pre-dilution haemofiltration (pre-HF)] in parallel. METHODS In this study, we compared post-HDF (Polyflux 170), pre-HDF (Polyflux...
Cell membranes prepared from senescent human diploid fibroblasts (HDF) inhibited entry into S phase by 35% when added to the medium of replicating young HDF. This membrane-associated inhibitory activity was (i) sensitive to trypsin, heat, and periodate, which suggests that the inhibitor is a glycoprotein, and (ii) not able to inhibit DNA synthesis in simian virus 40-transformed HDF, which indic...
BACKGROUND AND OBJECTIVES Theoretical advantages exist of online hemodiafiltration (HDF) over high-flux hemodialysis (HD), but outcome data are scarce. Our objective was to compare outcomes between these modalities. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We studied 858 incident patients in our incremental high-flux HD and online HDF program during an 18-yr period. We compared outcomes,...
Feeley and Pittman (Bull. World Health Organ. 28:347, 1963) speculated that a hemolysin (HL) destructive enzyme produced by El Tor vibrio at a late stage of growth lowers the HL titer. We proved the production of an HL-destructive factor (HDF) by strains of classical cholera and El Tor vibrio and established an in vitro method for quantitative titration of HDF. HL was prepared by growing a hemo...
Background: The aim of our study was to determine whether intermittent hemodiafiltration (HDF) leads to an alteration in monocyte antiviral activity as well as in the in vitro release of cytokines such as interleukin-12 (IL12), tumor necrosis factor-α (TNF-α) and interferon-α (IFN-α) by the same cells. Methods: We enrolled 25 patients undergoing HDF for 3.5-4 hours 3 times a week (12 men, 13 wo...
