The risk of intradialytic hypotension (IDH) is determined by various factors, among them dialysis modality and dialyzer membrane. We conducted a literature search in PubMed on November 1, 2016 and selected relevant randomized controlled and cross-over trials, and prospective and retrospective cohort studies published in English that investigated the association between IDH and dialysis modality and membrane, respectively. This literature search revealed 669 publications on dialysis modality, 64 on dialysis membrane, and 24 on acetate/bicarbonate dialysate...

Background Chronic metabolic acidosis is a frequent comorbidity in chronic kidney disease, especially in patients undergoing dialysis. Recent study data suggest that treatment of acidosis during dialysis with bicarbonate may result in increased levels of serum bicarbonate, which is associated with increased mortality. Methods We aimed to evaluate the current management of chronic metabolic acidosis in Germany: have recent study results been transferred into daily routine and are nephrologists aware of these new study data? Therefore, we did a survey with 17 questions among 2096 German nephrologists...

AIMS: We evaluated the impact of hemodialysis on mortality and hospital readmission in patients with cardiorenal syndrome. METHODS: All patients were NYHA IV functional class and underwent laboratory testing, echocardiography, and cardiac functional testing. Hemodialysis was indicated in patients with progressive decline of kidney function and consequent failure to titrate heart failure medication as well as in patients with hypervolemia that was resistant to conservative treatment with more than 4 annual hospitalizations due to heart failure and/or concomitant chronic kidney disease stage III - IV...

Hemodialysis patients can acquire buffer base (i.e., bicarbonate and buffer base equivalents of certain organic anions) from the acid and base concentrates of a three-stream, dual-concentrate, bicarbonate-based, dialysis solution delivery machine. The differences between dialysis fluid concentrate systems containing acetic acid versus sodium diacetate in the amount of potential buffering power were reviewed. Any organic anion such as acetate, citrate, or lactate (unless when combined with hydrogen) delivered to the body has the potential of being converted to bicarbonate...

BACKGROUND: Controlling blood pH during acute ventilatory failure and hypercapnia in individuals suffering from severe acute kidney injury (AKI) and undergoing continuous renal replacement therapy (CRRT) is of paramount importance in critical care settings. In this situation, the optimal concentration of sodium bicarbonate in the dialysate is still an unsolved question in critical care since high concentrations may worsen carbon dioxide levels and low concentrations may not be as effective in controlling pH...

During extracorporeal dialysis, some anticoagulation strategy is necessary to prevent the coagulation of blood. Heparin has historically been used as an anticoagulant because of its efficacy combined with low cost. However, a variable incidence of hemorrhagic complications (5-30%) has been documented in patients undergoing continuous renal replacement therapy (CRRT) with heparin as an anticoagulant. Citrate has anticoagulation properties secondary to its ability to chelate calcium, which is necessary for the coagulation cascade...

The history of dialysis and diet can be viewed as a series of battles waged against potential threats to patients' lives. In the early years of dialysis, potassium was identified as "the killer", and the lists patients were given of forbidden foods included most plant-derived nourishment. As soon as dialysis became more efficient and survival increased, hyperphosphatemia, was identified as the enemy, generating an even longer list of banned aliments. Conversely, the "third era" finds us combating protein-energy wasting...

Metabolic acidosis is associated with poor outcomes in CKD. Because impaired renal ammonium excretion is important in the pathogenesis of acidosis, urine ammonium excretion might be a better and perhaps earlier acid-base indicator of risk than serum bicarbonate, particularly in patients without acidosis. We evaluated the association between baseline ammonium excretion and clinical outcomes in African American Study of Kidney Disease and Hypertension participants (n=1044). Median daily ammonium excretion was 19...

BACKGROUND: Most hemodialysis patients have high Hepcidin-25 levels, which may be involved in the pathogenesis of several uremic complications related to an altered iron biology. The hemodialysis procedure itself can influence Hepcidin-25 levels by removing Hepcidin-25 and maybe stimulating its production due to a pro-inflammatory effect. METHODS: To assess the relationship between dialysis-related inflammation and intradialysis changes in Hepcidin-25, we performed a crossover trial in 28 hemodialysis patients to compare the effects on serum levels of Hepcidin-25 and inflammatory markers activated during dialysis [Tumor Necrosis Factor-α (TNF-α), Interleukin-6, C-reactive protein (CRP), Pentraxin-3] of a single dialysis session using a technique capable of reducing inflammation, HFR (Hemo Filtrate Reinfusion: a hemodiafiltration system combining convection, diffusion and adsorption) or bicarbonate-dialysis using either the same low-flux membrane as in the diffusion stage of HFR (LFBD) or a high-flux membrane (HFBD)...

♦ BACKGROUND: The use of pH-neutral peritoneal dialysis (PD) fluids low in glucose degradation products (GDP) may better preserve the peritoneal membrane and have fewer systemic effects. The effects of conversion from conventional to neutral-pH, low-GDP PD fluids in prevalent patients are unclear. Few studies on the role of neutral-pH, low-GDP PD have studied residual renal function, ultrafiltration, peritonitis incidence and technique failure, transport characteristics, and local and systemic markers of inflammation in prevalent PD patients...

Liver failure is a serious and often deadly disease often requiring MARS (Molecular Adsorbent Recirculating System) therapy. Choosing the safe and effective method of anticoagulation during artificial liver support systems seems to be very difficult and extremely important. The aim of this study was to assess effectiveness and safety of regional anticoagulation with citrate in liver failure patients during MARS. We used a single center observational study. We analyzed 158 MARS sessions performed in 65 patients: 105 (66...

Fresenius Medical Care's NaturaLyte dialysate has been associated with increased risk of sudden cardiac death by causing metabolic alkalosis from its acetate content based on retrospective data using pre-dialysis bicarbonate levels only. The study objective was to measure inter/intra-dialytic changes in serum bicarbonate and degree of alkalosis conferred by varying concentrations of NaturaLyte bicarbonate dialysate. Thirty-nine hemodialysis patients were divided into four groups based on prescribed bicarbonate dialysate concentrations; Group 1 (N = 9): 30-32 mEq/L, Group 2 (N = 5): 33-34 mEq/L, Group 3 (N = 10): 35-36 mEq/L, Group 4 (N = 15): 37-40 mEq/L...

BACKGROUND AND OBJECTIVES: Uncorrected metabolic acidosis leads to higher death risk in dialysis patients. We observed the relationship between metabolic acidosis status and mortality rate in patients on renal replacement therapy during a median follow up time of 60 months. METHODS: We studied 76 patients on an on-line hemodiafiltration. The dialysis adequacy was defined by Kt/V for urea. The Framingham risk score (FRS) points were used to determine the 10-year risk for coronary heart disease...

Metformin is recommended as the treatment of choice in patients with type 2 diabetes mellitus because of its efficacy, general tolerability and low cost. Recent guidelines have extended the use of metformin to patients with Chronic Kidney Disease (CKD) up to stage III. However, in the recent literature, cases of MALA (metformin-associated lactic acidosis) are increasingly reported. MALA is the most dangerous side effect of the drug, with an incidence rate of 2-9 cases per 100000 person-years of exposure. We report on two patients with accidental metformin overdose, severe lactic acidosis and acute kidney injury...

Chronic kidney disease is defined as progressive kidney dysfunction. The levels of various cytokines increase in hemodialysis (HD) patients. High levels of interleukins (ILs) and presence of metabolic acidosis are described as independent risk factors for morbidity and mortality in these patients. This study was designed to evaluate the relationship between IL-6 and IL-10 and serum bicarbonate and metabolic acidosis in HD patients. In this analytical crosssectional study, patients referred to the HD units of Loghman Hakim and Shahid Ashrafi Esfahani Hospitals were randomly selected...
