This paper describes a method to estimate interstitial fluid volume and peripheral blood volume (BVP) in hemodialysis (HD) patients using whole body (wBIS) and calf (cBIS) bioimpedance spectroscopy techniques. The aim of this study was to evaluate the usefulness of the technique. Thirty five HD patients were studied pre and post HD. Extracellular volume (ECV) and total body water (TBW) were measured using wBIS and cBIS. The calf resistances at 5 kHz (R5) and at 1000 kHz (R1000) respectively reflect ECV and TBW in the calf...

REVIEW
Jason A Chou, Kamyar Kalantar-Zadeh
PURPOSE OF REVIEW: Volume management in hemodialysis patients is often challenging. Assessing volume status and deciding how much fluid to remove during hemodialysis, the so-called ultrafiltration rate (UFR), has remained a conundrum. RECENT FINDINGS: To date there is no objective assessment tool to determine the needed UFR during each hemodialysis session. Higher volume overload or higher UFR is associated with poor outcomes including worse mortality and unfavorable clinical outcomes...

OBJECTIVES: The need for a central venous catheter has limited the widespread use of ultrafiltration in daily clinical practice for the treatment of acute heart failure (AHF) with overt fluid overload. We evaluated the feasibility of a new ultrafiltration device, the CHIARA (Congestive Heart Impairment Advanced Removal Approach) system, that utilizes a single-lumen cannula (17G, multi-hole) inserted in a peripheral vein of the arm. METHODS: In this multicenter, prospective, feasibility study, consecutive ultrafiltration treatments (lasting ≥6 hours and with an ultrafiltration rate ≥100ml/h) with the CHIARA device and a single peripheral venous approach were performed at 6 Italian hospitals...

Pregabalin (PGB) is a chemical derivative of the inhibitory neurotransmitter γ-aminobutyric acid, and is successfully used for the treatment of neuropathic pain. Substantial evidence suggests that d-serine, an endogenous co-agonist at the strychnine-insensitive glycine site of the NMDA receptor, counteracts the antinociceptive actions of PGB at the level of the spinal cord. In the present study, we examined the impact of PGB treatment on spinal d-serine content and NMDA receptor-mediated synaptic transmission in the superficial dorsal horn of peripheral nerve-ligated neuropathic mice...

BACKGROUND: Peritonitis and ultrafiltration failure remain serious complications of chronic peritoneal dialysis (PD). Dysfunctional cellular stress responses aggravate peritoneal injury associated with PD fluid exposure, potentially due to peritoneal glutamine depletion. In this randomized cross-over phase I/II trial we investigated cytoprotective effects of alanyl-glutamine (AlaGln) addition to glucose-based PDF. METHODS: In a prospective randomized cross-over design, 20 stable PD outpatients underwent paired peritoneal equilibration tests 4 weeks apart, using conventional acidic, single chamber 3...

Number of exotoxins like haemolysin, leukocidin, aerolysin etc. were reported from Aeromonas hydrophila. In this study, we report the haemolytic and cytotoxic effect of A. hydrophila culture supernatant (CS) that is specifically inhibited by lactose and also by serum and mucus of Nile tilapia (Oreochromis niloticus). Hence, we assume the presence of a secreted lectin in the CS. CS is toxic to peripheral blood leukocytes (PBL) of O. niloticus as revealed by MTT assay and by flow cytometry. DNA laddering assay indicates that CS causes necrosis to PBL...

BACKGROUND: The endothelium is a potentially valuable target for sepsis therapy. We have previously studied an extracorporeal endothelial cell therapy system, called the endothelial bioreactor (EBR), which prolonged the survival time of endotoxemia sepsis in swine. To further study of the therapeutic effects and possible mechanisms, we established a miniature EBR system for septic rats induced by cecal ligation and puncture (CLP). METHODS: In the miniature EBR system, the extracorporeal circulation first passed through a mini-hemofilter, and the ultrafiltrate (UF) was separated, then the UF passed through an EBR (a 1-mL cartridge containing approximately 2 × 10(6) endothelial cells grown on microcarriers) and interact with endothelial cells...

INTRODUCTION: Intradialytic hypertension with a prevalence of 15% among hemodialysis patients is with unknown pathophysiology, demographic, laboratoiy and clinical characteristic of patients, and it's influence on longtenn clinical effects (cardiovascular morbidity and mortality, rate of hospitalization). The aim of the study is to present the clinical, laboratoiy and demographic characteristics of patients with intradialytic hypertension in our dialysis center. MATERIALS AND METHODS: Out of 110 hemodialysis patients, 17 patients (15,45%) had intradialytic hypertension - started at a systolic pressure greater than 140 nun Hg or had an increase in systolic pressure more than 10 mm Hg during the session, and 17 patients were nonnotensive or had a drop in blood pressure dining the dialysis...

BACKGROUND: Our previous results showed that intrasynovial Rifamycin SV caused the lysis of synoviocites and freed the autoantigens which in turn stimulated the immunoregulatory rather than autoreactive T cell response in rheumatoid patients. Here, we hypothesize that disruption in vitro of peripheral blood mononuclear cells, by freeze/thawing or by lytic action of Rifamycin SV, would induce the release of endosomal pathogenic autoantigens from APCs present in the circulation, which could then be isolated from degrading enzymes by ultrafiltration...

We describe a case of 58-year-old man with septic shock due to Carbapenem-resistant Klebsiella pneumoniae (CR-Kp) bloodstream infections (BSI) who was successfully treated with a high dose association of amikacin and imipenem combined with continuous venovenous hemodiafiltration (CVVHDF). A Klebsiella pneumoniae (Kp) was isolated from the catheter culture and from two blood samples, drawn from the catheter before removal and from a peripheral vein. The Kp was intermediate to Amikacin (MIC = 16 μg/ml) and was resistant to all other antibiotics including Imipenem (MIC = 4 μg/ml), Colistin (MIC = 16 μg/ml) and Tigecycline (MIC = 4 μg/ml) according to the Clinical and Laboratory Standards Institute (CLSI) published in 2011...

Extensive usage of pharmaceutical and personal care products (PPCPs) and their discharge through domestic sewage have been recently recognized as a new generation environmental concern which deserves more scientific attention over the classical environmental pollutants. The major issues of this type of effluent addressed in this study were its colour, triclosan and anionic surfactant (SDS) content. Samples of cosmetic effluent were collected from different beauty treatment salons and spas in and around Kolkata, India and treated in bioreactors containing a bacterial consortium isolated from activated sludge samples collected from a common effluent treatment plant...

BACKGROUND AND OBJECTIVES: Ultrafiltration (UF) of excess fluid activates numerous compensatory mechanisms during hemodialysis (HD). The increase of both total peripheral and splanchnic vascular resistance is considered essential in maintaining hemodynamic stability. The aim of this study was to evaluate the extent of UF-induced changes in hepato-splanchnic blood flow and resistance in a group of maintenance HD patients during regular dialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Hepato-splanchnic flow resistance index (RI) and hepato-splanchnic perfusion index (QI) were measured in 12 chronic HD patients using a modified, non-invasive Indocyaningreen (ICG) dilution method...

Hemodialysis (HD) is usually performed with the gradually decreasing ultrafiltration rate (UFR) profile (dUFR). The aim of the present study was to compare the hemodynamic response to HD with the dUFR to that of HD with the gradually increasing UFR profile (iUFR). The study population included 10 patients (three women, mean age: 28 ± 8 years) undergoing maintenance HD who had reached dry weight without taking antihypertensive medications. Each patient received (in random order) one HD session with the dUFR and another with the iUFR (both with 3 h total UFR = 2200 mL)...

Early mortality is high in hemodialysis (HD) patients, but little is known about early cardiovascular event (CVE) rates after HD initiation. To study this we analyzed data in the AROii cohort of incident HD patients from over 300 European Fresenius Medical Care dialysis centers. Weekly rates of a composite of CVEs during the first year and monthly rates of the composite and its constituents (coronary artery, cerebrovascular, peripheral arterial, congestive heart failure, and sudden cardiac death) during the first 2 years after HD initiation were assessed...

Parathyroidectomy (PTx) seems to improve cardiovascular outcomes and reduce blood pressure levels. However, the effect of PTx on hemodynamic changes during hemodialysis (HD) is still overlooked. This was a prospective cohort design. Patients with end-stage renal disease on maintenance HD were included. Diabetes and nonsinusal rhythm were exclusion criteria. History of PTx was recorded. Finometer monitor was used to access parameters immediately pre- and post-HD sessions. Cardiac index (CI) variation (ΔCI) and peripheral arterial resistance variation (ΔPAR) were the variables of interest...

BACKGROUND/AIMS: Ultrafiltration that occurs during hemodialysis (HD) promotes profound alterations in a relatively short period of time. The dialysate content of bicarbonate (DBic) and potassium (DK) may have impact over intradialytic hemodynamics, which goes beyond ultrafiltration, and its impact was evaluated in a prospective cohort. METHODS: 30 patients under HD were submitted to hemodynamic assessment (HA) at the beginning and at the end of HD sessions, through a non-invasive method...

The mechanisms by which LDLs and HDLs cross the vascular endothelium from plasma into interstitial fluid are not understood, and have never been studied in humans in vivo. We determined whether the plasma-to-lymph clearance rates of LDL and HDL conform with those predicted by passive ultrafiltration through intercellular pores, or if it is necessary to invoke an active process such as receptor-mediated transcytosis. Plasma and afferent peripheral lymph were collected under steady-state conditions from 30 healthy men, and assayed for seven globular proteins of molecular radii 2...
