Filter by:Chronic Kidney Disease (CKD) is a known risk factor of cardiovascular morbidity and mortality. In CKD, decline of renal function results in the accumulation of uremic toxins in blood and tissue, such as Indoxyl Sulfate (IS). IS plasma level is predictive of mortality and cardiovascular disease (CVD). Patients with CKD have increased oxidative stress and circulating tissue factor (TF) levels. In vitro, IS induces an inflammatory, pro-oxidative and pro-coagulant phenotype on endothelial cells and activates TF. N-acetylcysteine (NAC) protects endothelial cells from the effects of IS. NAC reduces oxidative stress and production of activated TF. A prospective study evaluating an oral NAC treatment versus placebo in chronic hemodialysis patients showed a better cardiovascular outcome but the physiopathology was unclear. The hypothesis is that NAC reduces cardiovascular risk by its effect on uremic toxin-induced pro-coagulant TF production. The primary objective is to compare the effect of NAC intravenously administered at each dialysis session (2gram on 3 dialysis sessions per week) to placebo on circulating TF levels in patients with CKD on chronic hemodialysis after 4 weeks of treatment. The objective is to show a 33% decrease in circulating tissue factor (TF) levels in the NAC group compared to the control group. It is a randomized, double-blind, placebo-controlled crossover trial that includes chronic hemodialysis patients from La Conception Hospital (AP-HM) in Marseilles, France. This is an interventional biomedical research project. 20 patients will be included in each group and will receive during 4 weeks intravenous injection. This study will give a pathophysiological rationale for the use of NAC to reduce thrombotic and cardiovascular risk in patients with CKD. This step will provide the rationale for a clinical trial to reduce the occurrence of major cardiovascular events with IV NAC in hemodialysis (HD) patients.
Anti-neutrophil cytoplasmic antibodies (ANCA), directed against myeloperoxidase (MPO) and against proteinase 3 (PR3), have a pathogenic role during ANCA (AAV) vasculitis. Glomerular basement membrane (MBG) antibodies also have a direct pathogenic role in Goodpasture's syndrome and anti-MBG antibody glomerulonephritis (GN). In some patients, the severity of renal and / or pulmonary involvement justifies the rapid purification of these autoantibodies by an apheresis procedure, while waiting for the effect of immunosuppressive treatments aimed at reducing their production. During vasculitis, plasma exchange (PE) is recommended in patients with severe renal impairment or intra-alveolar hemorrhage (2012 KDIGO Clinical Practice Guideline for Glomerulonephritis). Given certain disadvantages related to plasma exchanges (low volume of purified plasma, non-selective technique for immunoglobulins (Ig), need for replacement solute, induction of coagulation disorders), immunoadsorption (IA), already used in transplantation, has been developed in these indications. IA has indeed greater selectivity for Ig with a probable better purification capacity due to higher volumes of plasma treated per session. The price of IA is however higher than that of EP. These two apheresis techniques, EP and IA, are commonly used in France during severe forms of vasculitis ANCA or anti-MBG, without the superiority of one or the other has been demonstrated. As a result of higher plasma volumes being purified, AI may allow faster purification of pathogenic antibodies. No studies to date have specifically compared the purification kinetics of these antibodies between EP and IA. The CINEVAS study (VAScularite Antibody Purification CINetic) is a multicentric pilot study whose main objective is to compare the purification kinetics of ANCA (anti-MPO or anti-PR3) and / or anti- MBG in patients treated with EP versus those treated with IA
There is evidence that the current dosing recommendations of ceftazidime in hemodialysis patients may not reach the critical pharmacokinetic/pharmacodynamics thresholds associated with maximal efficacy. The primary objective is to assess whether the standard doses of ceftazidime (1 or 2 g) administered at the end of the dialysis session (intermittent dialysis) allow to obtain a trough level equal or superior to 8 mg/L if the causative organism is not identified or 1 x the MIC if it is identified and its in vitro susceptibility to ceftazidime established. The secondary objectives will be (i) to assess whether a trough level equal or superior to 32 mg/L (if the causative organism is not identified) and 4 x its MIC (if identified and its in vitro susceptibility established) can be obtained; (ii) whether the criteria mentioned above also apply to the free fractions of ceftazidime; (iii) to assess whether reaching the desired free and total trough concentrations impacts the clinical outcome of the patient; (iv) to assess whether the main hemodialysis parameters impact on ceftazidime total and free serum concentrations; (v) to assess the impact of patient's residual renal function on the ceftazidime serum free and total concentrations; (vi) to assess the impact of potential drug-drug interactions on ceftazidime serum free and total concentrations; (vii) to assess how the MIC of the causative organism (if known) affects the expected effectiveness of ceftazidime. The study will be prospective and monocentric. Drug assay will be made High Performance Liquid Chromatography (HPLC) and UV photometric detection (confirmed by tandem mass spectrometry detection[HPLC-MS-MS]). Free concentration will be measured after separation by membrane sieving. The expected number of enrolled patients will be 20 (arbitrarily chosen but compatible with previous studies and the possibilities of the Institution in which the study will be performed. The standard dose of ceftazidime will be (i) a loading dose of 2 g followed by a maintenance dose of 1 g (the dose may be modified by the clinician in charge if deemed necessary and recorded accordingly). The data obtained will be used for pharmacokinetic modelling and population pharmacokinetics, followed by Monte-Carlo simulations to obtain population-wide predictions and to draw conclusions that could be applicable to a larger population.
This is a pilot study to test the utility of an integrated approach in the management of the anemia of chronic kidney disease through the administration of both an erythropoietic stimulating agent and iron. Subjects will be studied for 6 months during which all iron dosing will be recommended using a computer based tool using model predictive control. Comparisons will be made to the 6 months prior to enrollment in to the study.
The purpose of the study is to measure levels of any of the following AEDs (levetiracetam, phenobarbital, phenytoin, ketamine, valproic acid, lacosamide) in blood and effluent on critically ill patients receiving CRRT in order to characterize drug pharmacokinetics and optimize dosing strategies in patients on CRRT.
Aim 1 of the study is to identify the elements of a deprescribing intervention that address contextual factors specific to dialysis. Aim 2 of the study, described in this record, is to determine the feasibility of a deprescribing intervention tailored for older dialysis patients. Older adults receiving dialysis are often prescribed multiple medications. Some of these medications are used to treat symptoms, but they also can increase the chance of significant health problems. The purpose of this study is to identify if it is feasible to reduce the use of medications that have been identified as causing an increased risk for health problems.
