NCT02825589
Based on many previous data proving hypervolemia in chronic hemodialysis patients could lead to sleep apnea and poor sleep quality. The investigators conduct this trial to evaluate whether more accurate dry weight assessment with BIA in these patients can lead to better sleep quality (measured by sleep actigraphy and questionnaires). The investigators will enroll 30 chronic hemodialysis patients in hemodialysis unit of Ramathibodi hospital whose age \> 18 years with subclinical hypervolemic status and baseline Pittsburgh sleep quality index (PSQI) score \> 5 into study. Patients with bed-ridden status, alteration of consciousness and unstable hemodynamics will be excluded. Then eligible patients will be randomized into 2 groups, BIA-guided and standard clinical guided dry weight assessment. The investigators will assess participants' dry weight at beginning of study, 3rd month and 6th month. Sleep actigraphy parameters (eg. total sleep time, sleep efficiency), sleep questionnaires score, left ventricular mass index by echocardiography, ambulatory blood pressure monitoring and blood chemistry results were collected at beginning of study, the end of 1st, 3rd and 6th month. The primary outcome is change of sleep actigraphy parameters between the groups. The secondary outcomes are change of sleep questionnaires scores, change of left ventricular mass index, change of ambulatory BP monitoring and also cardiovascular complications between groups.
NCT03634904
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.
NCT02285075
The current study aimed to explore the pharmacokinetics of temocillin in patients treated with haemodialysis and to demonstrated whether or not the pharmacodynamics target of a time above a MIC of 16 mg/L of more than 40 and 60 % of the dosing interval could be obtained with a dosing schedule of 1 gram/24 hours, 2 gram/48 hours and 3 gram/72 hours, all of these doses given after haemodialysis sessions only.
NCT01015313
The primary aim of this study is to investigate whether intensive sodium management by dietary sodium restriction and by preventing positive sodium balance during dialysis can be successfully applied in chronic hemodialysis patients. Secondary aims are to test if sodium restriction has positive effects on the frequency of hospital admissions, blood pressure, fluid overload, quality of life and residual renal function.
NCT01946841
The objective of this unblinded study is to assess the nutritional effects of a 12 weeks administration of the specific enteral nutrition (SEN) RealDiet®Renal pockets, as well as the impact on the patients' quality of life.
NCT01578421
The purpose of the study is to compare clearance and removal rates of phosphate, ß2-microglobulin (ß2-m) and leptin and albumin loss with different dialyser membranes during post-dilution online hemodiafiltration.
NCT00560976
The purpose of this study is to assess changes in serum levels of the siderophore binding protein NGAL by hemodialysis without and with intravenous iron administration
