INTRODUCTION: Uremic polyneuropathy is very common among patients with Chronic Kidney Disease (CKD). The patients have electrophysiologic signs of impaired nerve function, although a lower percentage of patients are symptomatic. Electrophysiological parameters are quantitative indices of Polyneuropathy (PNP) severity. AIM: To assess the frequency of PNP in patients on long term Peritoneal Dialysis (PD) treatment. MATERIALS AND METHODS: Twenty three PD patients were analysed, who were receiving dialysis for at least five years and the study population divided into two groups according to duration of PD treatment...

Background -A decrease in sodium intake has been shown to lower blood pressure, but data from cohort studies on the association with cardiovascular and renal outcomes are inconsistent. In these studies sodium intake was often estimated using a single baseline measurements, which may be inaccurate considering day-to-day changes in sodium intake and sodium excretion. We compared the effects of single versus repetitive follow-up 24-hour urine samples on the relation between sodium intake and long-term cardiorenal outcomes...

BACKGROUND: Poor physical performance and protein-energy wasting (PEW) are health issues of major concern in haemodialysis patients. The conventional haemodialysis (CHD) regime, three times per week 3-5 h, is subject of discussion because of high morbidity and mortality rates. When patients switch from CHD to longer dialysis sessions, i.e. nocturnal haemodialysis (NHD), improvement in protein intake and increase in body weight is seen. However, it is unclear whether physical performance and more important aspects of PEW, such as body composition, improve as well...

BACKGROUND: Polyomavirus nephropathy (BKVN) is an important cause of chronic allograft dysfunction (CAD). Recipient determinants (male sex, white race, and older age), deceased donation, high-dose immunosuppression, diabetes, delayed graft function (DGF), cytomegalovirus infection, and acute rejection (AR) are risk factors. Reducing immunosuppression is the best strategy in BKVN. The objective of our study was to evaluate CAD progression after therapeutic strategies in BKVN and risk factors for graft loss (GL)...

INTRODUCTION: Recipients of conventional hemodialysis (CHD; 3-4 h/session, 3 times/week) experience volume expansion and nutritional impairment which may contribute to high mortality. Prolongation of sessions with in-centre nocturnal hemodialysis (INHD; 7-8 h/session, 3 times/week) may improve clinical outcomes by enhancement of ultrafiltration and uremic toxin removal. MATERIALS AND METHODS: In this prospective cohort study, 56 adult patients who were receiving maintenance CHD for at least 90 days were assigned to CHD (patients who remained in CHD) and INHD (patients who switched to INHD) groups...

Anemia is a common complication in chronic kidney disease (CKD) patients receiving hemodialysis. The effect of high-flux dialysis (HFD) on anemia remains unclear. This prospective study aimed to evaluate the effect of HFD on anemia, and the potential of soluble transferrin receptor (sTfR) as a marker of iron status and erythropoiesis in CKD patients on hemodialysis. Forty patients, who switched from conventional low-flux dialysis to HFD for 12 months, were enrolled in this study. The levels of sTfR, hemoglobin, iron, and nutritional markers, as well as the dose of recombinant human erythropoietin (rhEPO) and use of chalybeate were determined at 0, 2, 6, and 12 months after starting HFD...

Morganella morganii is a rare cause of peritonitis in patients on peritoneal dialysis (PD). Most of the reported cases have resorted to a switch to hemodialysis. We herein report a case of peritonitis due to M. morganii resistant to third-generation cephalosporins, which was treated successfully with intraperitoneal (IP) tobramycin followed by oral ciprofloxacin. Early microbiologic diagnosis is essential in the treatment of peritonitis from rare microorganisms such as Morganella morganii, and appropriate antibiotic therapy is the key to avoiding catheter loss and subsequent switch to hemodialysis...

BACKGROUND: Kidney transplantation is known to increase the survival of dialysis patients by ameloriating cardiac status, including both systolic and diastolic functions. We aimed to evaluate the role of immunosuppressive drug regimens on cardiac functions of kidney transplant recipients (KTRs). METHODS: We prospectively evaluated 120 KTRs immediately before and 1 year after the kidney transplantation, using tissue Doppler echocardiography. A triple immunosuppressive therapy including tacrolimus, mycophenoloic acid (MPA), and prednisolone was started for all patients...

ABSTRACTHemodialysis (HD) and peritoneal dialysis (PD) represent two complementary modalities of renal replacement therapy (RRT) for end-stage renal disease patients. Conversion between the two modalities is frequent and more likely to happen from PD to HD. Every year, 10% of PD patients convert to HD, suggesting the need for recommendations on how to proceed with the creation of a vascular access in these patients. Criteria for selecting patients who would likely fail PD, and therefore take advantage of a backup access, are undefined...

Here we discuss studies of the structure, folding, oligomerization and amyloid fibril formation of several proline mutants of human stefin B, which is a protein inhibitor of lysosomal cysteine cathepsins and a member of the cystatin family. The structurally important prolines in stefin B are responsible for the slow folding phases and facilitate domain swapping (Pro 74) and loop swapping (Pro 79). Moreover, our findings are compared to β₂-microglobulin, a protein involved in dialysis-related amyloidosis...

INTRODUCTION: Unplanned dialysis start (UPS) associates with worse clinical outcomes, higher utilisation of healthcare resources, lower chances to select dialysis modality and UPS patients typically commenced in-centre haemodialysis (HD) with central venous catheter (CVC). We evaluated patient outcomes and healthcare utilisation depending on initial dialysis access (CVC or PD catheter) and subsequent pathway of UPS patients. METHODS: In this study patient demographics, access procedures, hospitalisations, and major infectious complications were analysed over 12 months in 270 UPS patients...

Most patients initiating hemodialysis have residual renal function (RRF). Whereas RRF is monitored prior to commencing hemodialysis, once dialysis is started most centres simply rely on dialyzer urea clearance to determine adequate uremic toxin clearance and disregard the effect of RRF. However sustaining RRF is important for the dialysis patient, as RRF reduces inter-dialytic weight gains, increases middle molecule and protein bound toxin clearances and is associated with better quality of life assessments...

β-2-Microglobulin (β2m) forms amyloid fibrils in the joints of patients undergoing dialysis treatment as a result of kidney failure. One of the ways in which β2m can be induced to form amyloid fibrils in vitro is via incubation with stoichiometric amounts of Cu(II). To better understand the structural changes caused by Cu(II) binding that allow β2m to form amyloid fibrils, we compared the effect of Ni(II) and Zn(II) binding, which are two similarly sized divalent metal ions that do not induce β2m amyloid formation...

Acute dialyser reactions in patients treated by haemodialysis are uncommon. We present two cases of such reactions, both in patients using a polysulfone, steam-sterilised dialyser. Patient 1 suffered from recurrent attacks of acute dyspnoea, hypoxia and hypotension that occurred early in dialysis sessions, whereas patient 2 presented with unexplained episodes of severe hypotension and vomiting in the initial phases of dialysis. After switching to a cellulose triacetate dialyser, both patients became asymptomatic during all subsequent dialysis sessions, but intentional (patient 1) and accidental (patient 2) rechallenge with the polysulfone dialyser induced an immediate recurrence of the symptoms...
