The invention of dialysis has been a phenomenal advance in the treatment of kidney failure. The introduction of artificial kidneys in clinical care remains one of the most successful lifesaving interventions in modern medicine. Its glory, however, has been tempered by poor long-term outcomes and a negative qualitative impact on the lives of patients who suffer from an extremely complex, burdensome, and restricted life on dialysis. There remains a huge gap in patient well-being and outcomes between artificial kidney treatments and kidney transplantation...

Cardiovascular disease is a major concern in patients with end-stage kidney disease (ESKD). Inflammation induced by retention of uremic toxins, of which a substantial fraction has a molecular weight in the middle molecular range, has been associated with increased cardiovascular risk. In an attempt to reduce inflammation and thus cardiovascular toxicity in patients with ESKD, hemodiafiltration (HDF) has been promoted to enhance the clearance of middle molecular weight substances during dialysis. However, HDF increases the technical complexity and costs, and requires ultrapure dialysis fluid...

The removal of larger middle molecules, such as free immunoglobulin light chains (FLC), is poor with most currently used dialysis technologies. While hemodiafiltration (HDF) provides enhanced clearance of middle molecules compared to high-flux hemodialysis (HD), this technique is currently not approved in some regions and, hence, not accessible for all patients. The retention of middle molecules is thought to be one factor, which contributes to excessive morbidity and mortality in HD patients. The development of medium cut-off (MCO) dialysis membranes is aimed at a more efficient clearance of larger uremic toxins while retaining albumin and may extend the benefit of enhanced solute removal to more patients...

End-stage renal disease (ESRD) has become a challenging health problem worldwide. Currently, ESRD patients treated with hemodialysis mainly undergo low-flux hemodialysis, high-flux hemodialysis (HF-HD), or hemodiafiltration (HDF). The clearance of middle and large molecules is, however, quite insufficient as regards HF-HD, HDF, and on-line HDF. An unsatisfactory prognosis has led to improved dialysis technology and materials; both protein-leaking membranes and high cut-off membranes increase the clearance of uremic toxin, but in clinical application they may induce albumin loss...

Recently, intensive care physicians have focused on continuous hemodiafiltration with a cytokine-adsorbing hemofilter in the treatment of sepsis. We aimed to establish extracorporeal circulation in a rat sepsis model to evaluate the cytokine removal properties of mini-modules using two types of membrane materials. Rats were divided into polyester polymer alloy (PEPA) and cellulose triacetate (CTA) groups as membrane materials of mini-modules. One hour after 0.1 mg/kg of lipopolysaccharide administration, continuous hemofiltration (CHF) was started in each group...

In Japan, 20-50 cases of leptospirosis are reported annually, typically involving farmers or returnees from tropical areas. Here, we report five indigenous leptospirosis cases that occurred in the Tokyo urban area. All cases were male (mean age 65.8 ± 4.7 years) and presented with clinical features including high fever, acute kidney injury, and jaundice. Three cases presented with pulmonary infiltration and ground glass opacity on admission. Two of the five patients were intubated and underwent continuous hemodiafiltration...

We report a case of lethal hepatorenal insufficiency in a 52-year-old man who received successful simultaneous hepatorenal transplantation from a deceased donor. The patient had undergone live-donor liver transplantation for type-C hepatitis and liver cirrhosis 11 years before he developed graft liver dysfunction due to recurrent viral hepatitis and cirrhosis. At that instance, he also developed end-stage renal dysfunction due to calcineurin inhibitor nephropathy and hepatorenal syndrome. Although he needed three open hemostases and abundant blood transfusion, he was withdrawn from continuous hemodiafiltration on the 55th day and discharged from the hospital on the 272nd day postoperatively...

BACKGROUND: No effective treatment is currently available and dialysis related amyloidosis continues to be invalidating in long-term dialysis patients. A recent case series reported reduction of osteoarticular pain on doxycycline treatment, extending the indications of this drug, used in other uncommon forms of amyloidosis, to dialysis patients. Explanations of the antalgic effect were the anti-inflammatory properties and anti-coiling effects of tetracycline. CASE PRESENTATION: Our report regards a 54-year-old woman, who was never transplanted and has been on hemodialysis and hemodiafiltration for overall 37 years, due to renal hypoplasia...

INTRODUCTION AND OBJECTIVE: Higher infusion volumes (IV) in online hemodiafiltration (OL-HDF) are associated with better survival. The IV depends mainly on blood flow (Qb). The objectives of our study were to evaluate the influence of the caliber of arteriovenous fistula (AVF) puncture needles on the total convective volume and other characteristics of OL-HDF, and to investigate possible adverse effects. MATERIAL AND METHODS: Prospective intervention study analyzing six sessions of postdilution OL-HDF with 14G needles and six sessions with 15G needles in the same patients, to compare results of efficacy and safety...

BACKGROUND: Regional citrate anticoagulation (RCA) is being used increasingly in continuous renal replacement therapy (CRRT) as a safer alternative to heparin. However, complex metabolic control to avoid side effects have generated discrepancies about its introduction into everyday practice. We aimed to compare both anticoagulation techniques in terms of efficacy, safety and feasibility. METHODS: Observational retrospective study performed in 3 specialized ICUs in patients receiving CVVHDF with RCA between January 2013 and May 2016...

Hemodiafiltration (HDF) is a renal replacement therapy which is based on the principles of diffusion and convection for the elimination of uremic toxins. A significant and increasing number of end stage renal disease (ESRD) patients are treated with HDF, even in the absence of definite and conclusive survival and anemia treatment data. However, its effects on red blood cell (RBC) physiological features have not been examined in depth. In this study, ESRD patients under regular HDF or conventional hemodialysis (cHD) treatment were examined for RBC-related parameters, including anemia, hemolysis, cell shape, redox status, removal signaling, membrane protein composition and microvesiculation, in repeated paired measurements accomplished before and right after each dialysis session...

BACKGROUND: Recent data suggest that the use of medium cut-off (MCO) dialyzers in hemodialysis (HD) promotes greater clearance and reduction ratio (RR) for myoglobin and other large-sized molecules than on-line hemodiafiltration (ol-HDF), but its effects on β2-microglobulin are not clear. We compared RR and clearances of small and middle-sized molecules between high-flux ol-HDF and MCO (Theranova) dialyzer in HD (MCO-HD) as well as nutritional parameters. MATERIALS AND METHODS: We retrospectively analyzed 10 patients treated first with ol-HDF who were thereafter switched to MCO-HD over a 1-year period...

Chronic malnutrition is a common problem in patients with end-stage renal disease on hemodialysis. Some studies have reported albumin loss into dialysis fluid during postdilution online hemodiafiltration (OL-HDF). The aim of the study was to assess the nutritional status of patients on high-volume OL-HDF and to demonstrate that higher convective clearances are not associated with malnutrition due to possible loss of nutrients with ultrafiltration. Demographic and clinical data, corporal composition with bioimpedance spectroscopy, dialysis features, albumin loss into dialysis fluid and laboratory parameters were collected in twenty-eight patients with ESRD undergoing postdilution OL-HDF with stable convective volumes over 28 L/session...

BACKGROUND: Continuous renal replacement therapies (CRRTs) either as continuous venovenous hemofiltration (CVVH) or hemodiafiltration (CVVHD) are used frequently in critically ill children. Many clinical variables and technical issues are known to affect the result. The factors that could be modified to increase the survival of renal replacement are sought. As a contribution, we present the data on 104 patients who underwent CRRT within a 7-year period. MATERIALS AND METHOD: A total of 104 patients admitted between 2009 and 2016 were included in the study...

BACKGROUND: Ethylene glycol intoxication causes severe metabolic acidosis and acute kidney injury. Fomepizole has become available as its antidote. Nevertheless, a prompt diagnosis is not easy because patients are often unconscious. Here we present a case of ethylene glycol intoxication who successfully recovered with prompt hemodialysis. CASE PRESENTATION: A 52-year-old Japanese male was admitted to a local hospital due to suspected food poisoning. The patient presented with nausea and vomiting, but his condition rapidly deteriorated, with worsening conscious level, respiratory distress requiring mechanical ventilation, hypotension, and severe acute kidney injury...

A 35-year-old woman intentionally took 40,000 mg of lithium carbonate, and she was transferred to our hospital with nausea, vomiting, and diarrhea. She was diagnosed as having bipolar disorder 10 years ago and was receiving oral lithium therapy. Blood test results on arrival were remarkable for a negative anion gap of -2.1 and later, the serum lithium level turned out to be as high as 15.4 mEq/L. Intubation was required because of disrupted consciousness, and continuous hemodiafiltration (CHDF) was immediately started in the intensive care unit to obtain constant removal of lithium...

After dialysis ends, urea continued movement causes rebound postdialysis, with values at about 20%. New techniques have been incorporated into hemodialysis, but their relationship with rebound has not yet been studied. This study aimed to quantify urea rebound at 30-min postdialysis during sessions using polysulfone filters and high-flow versus online hemodiafiltration, and to define its correlation with body composition measured by bioimpedance by a cross-sectional study with 69 patients (December 2015 to January 2016)...

A female hemodialysis patient with galactorrhea due to hyperprolactinemia was treated with different dialysis modalities to assess the effect on prolactin levels. A single session of both high-flux hemodialysis and hemodiafiltration resulted in decreased prolactin levels (16,6% and 77,2%, resp.). However, baseline prolactin levels measured immediately before the next dialysis session did not change markedly. After cabergoline treatment was started, prolactin levels normalized and galactorrhea disappeared. Thus, dopaminergic inhibition of prolactin secretion might be reduced in patients with end-stage renal disease...

INTRODUCTION: Hemodialysis patients are pro-thrombotic. Higher volume online postdilutional hemodiafiltration (OL-HDF), with increasing hematocrit increases the risk of clotting in the extracorporeal circuit (ECC). We wished to determine whether OL-HDF increased platelet activation and ECC clotting. METHODS: Coagulation parameters, platelet, white cell, and endothelial activation markers were measured at the start and end of dialysis sessions in 10 patients and also pre- and post-dialyzer after 15 minutes using two different dialyzers designed for high volume OL-HDF; cellulose triacetate (TAGP) and polysulphone (PS), and polyvinylpyrrolidone (PVP)...

Erythropoietin resistance index calculation has been used as a tool to evaluate anemia response to erythropoietin therapy. Very little has been reported in its use when using darbepoetin and factors influencing in Arab patients. Darbepoetin resistance index (DRI) was calculated in all our patients using darbepoetin. This was correlated to demographic, clinical, and laboratory parameters. Of the 250 patients, 40.4% were diabetic, 71.1% on hemodialysis, and 28.6% on hemodiafiltration), 23.9% with PermCaths (PC), and 76...
