[Out-of-center blood pressure measurements in dialysis patients: Feasibility and comparison of methods].

The European Renal Association-European Dialysis and Transplant Association (ERA-EDTA)/European Society of Hypertension (ESH) recommends out-of-center blood pressure measurements, self-blood pressure measurement or ambulatory blood pressure measurement in dialysis patients. However, the feasibility of out-of-center blood pressure measurements in routine care is not known. The objective of our study was to quantify it as "a priori" i.

COVID-19 in Patients Undergoing Hemodialysis: Prevalence and Asymptomatic Screening During a Period of High Community Prevalence in a Large Paris Center.

Rationale & Objective: Due to extensive comorbid conditions, coronavirus disease 2019 (COVID-19) has a poor prognosis in people receiving maintenance hemodialysis. In this article, we describe our experience with 200 maintenance hemodialysis patients in a hemodialysis center that used universal reverse transcriptase-polymerase chain reaction testing, including 38 COVID-19-positive patients.

Study Design: Descriptive observational cohort, including the time line of patient diagnoses along with contextual events including precautions, testing, screening algorithms, clinical diagnostics and therapy, and the clinical course of COVID-19-infected patients and their final outcomes.

Isonatric Dialysis Biofeedback in Hemodiafiltration with Online Regeneration of Ultrafiltrate in Hypertensive Hemodialysis Patients: A Randomized Controlled Study.

Unlabelled: Dialysis biofeedback in hemodiafiltration with online regeneration of ultrafiltrate (HFR) could help to improve arterial hypertension. We evaluated the impact of isonatric HFR (HFR-iso) on hypertension control compared to conventional HFR. Forty-seven hemodialysis patients were included and randomized (ratio 2/1) HFR-iso versus HFR during 24 dialysis sessions.

L-carnitine treatment in incident hemodialysis patients: the multicenter, randomized, double-blinded, placebo-controlled CARNIDIAL trial.

Background: L-carnitine levels decrease rapidly and steadily with duration of hemodialysis, and carnitine depletion can impair response to recombinant human erythropoietin (rHuEPO). The study hypothesis was that L-carnitine supplementation during the first year of hemodialysis would improve this response.

Design, Setting, Participants, & Measurements: From October 2006 through March 2010, this multicenter, randomized, double-blinded study assigned 92 incident hemodialysis patients to receive placebo or 1 g of intravenous L-carnitine after each dialysis session for 1 year.

Effect of a plasma sodium biofeedback system applied to HFR on the intradialytic cardiovascular stability. Results from a randomized controlled study.

Background: Intradialytic hypotension (IDH) is still a major clinical problem for haemodialysis (HD) patients. Haemodiafiltration (HDF) has been shown to be able to reduce the incidence of IDH.

Methods: Fifty patients were enrolled in a prospective, randomized, crossover international study focussed on a variant of traditional HDF, haemofiltration with endogenous reinfusion (HFR).

Presentation and outcome of patients with systemic amyloidosis undergoing dialysis.

Background And Objectives: Light chain (AL) and secondary (AA) amyloidosis usually present as a systemic disease frequently involving the kidney and leading to ESRD. Data regarding patients with AA or AL amyloidosis undergoing dialysis remain scarce.

Design, Setting, Participants, & Measurements: We retrospectively studied patients with AA or AL amyloidosis who started dialysis in five French centers between January 1, 1995 and December 31, 2005.

Effects of oral vitamin C supplementation in hemodialysis patients: a proteomic assessment.

Evidence indicates that oxidative stress is present in dialysis patients, and is associated with vitamin C deficiency. Limited data are available regarding the effects of vitamin C supplementation on oxidative stress and inflammation markers in these patients. Moreover, there are no data available on plasma polypeptide fingerprints by proteome analysis before and after vitamin C supplementation.

Effects of oral vitamin C supplementation on oxidative stress and inflammation status in haemodialysis patients.

Background: There is increasing evidence for the presence of oxidative stress and vitamin C deficiency in dialysis patients. Limited data, however, are available regarding the effects of vitamin C supplementation on oxidative stress and inflammation markers in such patients.

Methods: We ran a prospective, randomized, open-label trial to assess the effects of oral vitamin C supplementation (250 mg three times per week) for 2 months on well-defined oxidative and inflammatory markers in 33 chronic haemodialysis (HD) patients.

Increased pasma S-nitrosothiol concentrations predict cardiovascular outcomes among patients with end-stage renal disease: a prospective study.

The plasma concentrations of S-nitrosothiols, which are circulating nitric oxide metabolites with potential biologic activity, are increased among patients undergoing chronic hemodialysis (HD). However, the ability of S-nitrosothiols to release nitric oxide at physiologically relevant sites may be reduced among HD patients, because of impaired availability and/or activity of factors involved in S-nitrosothiol breakdown. The resultant lack of S-nitrosothiol bioavailability could contribute to the high cardiovascular risk for such patients.

Prognostic value of cardiac markers in ESRD: Chronic Hemodialysis and New Cardiac Markers Evaluation (CHANCE) study.

Background: Cardiac disease is the main cause of mortality in long-term hemodialysis patients. Cardiac troponins (cTn) have been proposed to be markers of cardiac damage, but their value is still debated in hemodialysis patients. The aim of this prospective study is to assess the prognostic value of biochemical cardiac markers in long-term hemodialysis patients.
