Reverse pseudohyperkalemia is a term used to describe in vitro, falsely elevated potassium concentrations in plasma specimens that occur in association with extreme leukocytosis and are commonly associated with hematologic malignant neoplasms. Tumor lysis syndrome is an in vivo lysis of tumor cells that leads to elevated levels of potassium, uric acid, phosphate, and lactate dehydrogenase, as well as decreased calcium concentrations. Herein, we report a case of a 66-year-old Caucasian man with stage IV mantle-cell lymphoma who has elevated levels of potassium, uric acid, and phosphorus, as well as a white blood cell (WBC) count greater than 100,000 cells per mm3...

Background: . Protein-energy wasting (PEW) in end-stage renal disease (ESRD) patients is associated with increased morbidity and mortality, but options for treatment are limited. Growth hormone (GH) increases insulin-like growth factor 1 (IGF-1), with improved nutritional parameters, but must be given subcutaneously and does not provide normal GH secretion patterns. MK-0677, an oral ghrelin receptor agonist (GRA), maintains normal GH secretion and increases lean body mass in normal subjects; it has not been studied in dialysis patients, an essential step in assessing efficacy and safety prior to clinical trials...

Background: Extracorporeal treatments (ECTRs) are used for different conditions, including replacement of organ function and poisoning. Current recommendations for ECTRs in various poisonings suggest that intermittent haemodialysis (IHD) is the most efficient technique. However, the practicality of these recommendations is poorly defined in view of limited information on availability and cost worldwide. Methods: A survey invitation to an Internet-based questionnaire was emailed between January 2014 and March 2015 to members of international societies to determine the availability, time to initiation and cost of ECTRs (including filters, dialysate, catheter, anticoagulant and nursing/physician salary)...

Background.: During the follow-up in a randomized controlled trial (RCT), participants may receive additional (non-randomly allocated) treatment that affects the outcome. Typically such additional treatment is not taken into account in evaluation of the results. Two pivotal trials of the effects of hemodiafiltration (HDF) versus hemodialysis (HD) on mortality in patients with end-stage renal disease reported differing results. We set out to evaluate to what extent methods to take other treatments (i...

Background.: Hemodialysis (HD) patients have an increased risk of thrombosis. Endothelial progenitor cells (EPCs), which function in vascular repair, are deficient in HD patients. Nonetheless, the relationship between EPC deficiency and thrombosis in HD patients is unknown. Methods.: From January 2010 to December 2012, circulating levels of EPCs that were positive for CD34 and kinase insert domain receptor (KDR) were measured in 269 HD patients. Patients received prospective follow-ups at 6-month intervals until May 2015...

: Patients on hemodialysis must adjust their life plans to the treatment. They are aware of losing their health and independence. Therefore, acceptance of illness (AI) is important and allows the patient to adjust to new situation and alleviates negative emotions The aim of study was to assess the impact of AI and other socioclinical variables on hemodialysis patients' quality of life (QoL).The study included 100 patients aged 20-85 (M = 57), treated with hemodialysis for at least 2 years. Two validated instruments were used: the Acceptance of Illness Scale (AIS) and the World Health Organization Quality of Life questionnaire...

BACKGROUND: The mortality of dialysis patients is 10- to 100-fold higher than in the general population. Baseline serum PTH levels, and more recently, changes in serum PTH levels (ΔPTH) over time, have been associated to mortality in dialysis patients. METHODS: We explored the relationship between ΔPTH over 1 year with mortality over the next year in a prospective cohort of 115 prevalent hemodialysis patients from a single center that had median baseline iPTH levels within guideline recommendations...

It was the purpose to quantify the hemodynamic effects of a bolus of hypertonic glucose injected into the extracorporeal system in a group of stable and non-diabetic patients during hemodialysis (HD).Glucose and electrolytes were measured in frequent intervals. Arterial blood pressures and heart rates were continuously recorded by non-invasive vascular unloading technique. Beat-to-beat stroke volume, cardiac output, and total peripheral resistance were determined by Modelflow method. Relative blood volumes were continuously measured by ultrasonic and optical means...

OBJECTIVE: We studied the diagnostic value of CK-MB and troponin (cTnI) in uremia with acute left ventricular failure patients. PATIENTS AND METHODS: We enrolled 130 uremia patients with maintenance hemodialysis (MHD) and divided them into two groups: (i) the observation group with patients suffering from acute left ventricular failure (n=30) and (ii) the control group which contained cases without acute left ventricular failure (n=100). We verified CK-MB, cTnI, serum creatinine, blood urea nitrogen, pro-BNP and LVEF levels at 6 h, 12 h, 24 h, 48 h, 72 h, 7 d and 14 d after the attack and carried out 1-year follow-up to compare total mortality and cardiogenic mortality...

REVIEW
Carlo Basile, Francesco Gaetano Casino, Kamyar Kalantar-Zadeh
Most people who make the transition to maintenance dialysis therapy are treated with a fixed dose thrice-weekly hemodialysis regimen without considering their residual kidney function (RKF). The RKF provides effective and naturally continuous clearance of both small and middle molecules, plays a major role in metabolic homeostasis, nutritional status, and cardiovascular health, and aids in fluid management. The RKF is associated with better patient survival and greater health-related quality of life, although these effects may be confounded by patient comorbidities...

BACKGROUND: This case report describes a spontaneous tumor lysis syndrome due to a rare solid tumor. CASE PRESENTATION: A 65-year-old white woman had tumor lysis syndrome, which represent a dangerous oncological emergency. This syndrome occurs usually with a hematological tumor, but in this case our patient had a solid tumor, which was a rare extraskeletal osteosarcoma, localized in her pelvic region. She also had lung metastases and bilateral hydronephrosis. After spontaneous tumor lysis syndrome, she had acute renal insufficiency, which was treated with hemodialysis and successively with rasburicase, Kayexalate (sodium polystyrene sulfonate), and febuxostat...

Yassamine Bentata
Infectious endocarditis (IE), a complication that is both cardiac and infectious, occurs frequently and is associated with a heavy burden of morbidity and mortality in chronic hemodialysis patients (CHD). About 2-6% of chronic hemodialysis patients develop IE and the incidence is 50-60 times higher among CHD patients than in the general population. The left heart is the most frequent location of IE in CHD and the different published series report a prevalence of left valve involvement varying from 80% to 100%...

Osmotic changes in plasma are assumed to cause cerebral swelling in hemodialysis patients. We investigated the acute effect of low-flux hemodialysis (HD) (removal of small molecules) and pre-dilution hemodiafiltration (pre-HDF) (additional removal of larger molecules) on cerebral compartment volumes using quantitative magnetic resonance imaging (MRI) in chronic uremic patients. Twelve patients underwent a session of HD and pre-HDF in a randomized crossover study with equal ultrafiltration. MRI was performed immediately before and after dialysis...
