BACKGROUND: Plasma level of N-terminal pro-brain natriuretic peptide (P-NTproBNP) is a useful marker in prediction of mortality in peritoneal dialysis (PD) patients. However, the predictive value of spent dialysate counterpart (D-NTproBNP) of plasma NTproBNP on mortality and dropout is not known. MATERIALS AND METHODS: Simultaneous P-NTproBNP and D-NTproBNP assays were performed after an overnight dwell in 44 scheduled ambulatory PD patients. Patients were followed for ~ 47 months...

Mass spectrometric glycomics was used as an innovative approach to identify biomarkers in serum and dialysate samples from peritoneal dialysis (PD) patients. PD is a life-saving treatment worldwide applied in more than 100,000 patients suffering from chronic kidney disease. PD treatment uses the peritoneum as a natural membrane to exchange waste products from blood to a glucose-based solution. Daily exposure of the peritoneal membrane to these solutions may cause complications such as peritonitis, fibrosis and inflammation which, in the long term, lead to the failure of the treatment...

RTx remains challenging in children under 3 years of age. This single-center study reviewed the medical records of children <3 years transplanted since 1987 (N = 32, Group 1). They were matched for donor type and RTx period with children aged 3-13 years (N = 32, Group 2) and 13-18 years (N = 32, Group 3). There were no between-group significant differences regarding distributions of gender, primary renal disease, proportion of dialysis before RTx, and growth (SDS). Compared to Groups 2 and 3, Group 1 had more peritoneal dialyses (P < ...

Dialysis patients are at increased risk for muscle wasting, and time efficient screening tests are required for to allow for early detection. Creatinine kinetics have been advocated to estimate lean body mass (LBM) in peritoneal dialysis (PD) patients, and can be readily calculated in clinical practice from peritoneal dialysate effluent and urine collections. Bioimpedance is increasingly available, and we compared methods in 434 PD patients (55% men, 33.3% diabetics), mean age 55.2 ± 16.2 years. LBM was lower by creatinine kinetics (47...

Peritoneal protein clearance (PPCl) depends upon vascular supply and size selective permeability. Some previous reports suggested PPCl can distinguish fast peritoneal membrane transport due to local or systemic inflammation. However, as studies have been discordant, we wished to determine factors associated with an increased PPCl. Consecutive patients starting peritoneal dialysis (PD) who were peritonitis-free were studied. Data included a baseline peritoneal equilibration test (PET), measurement of dialysis adequacy, 24-h dialysate PPCl and body composition measured by multifrequency bioimpedance...

Steady-state pharmacokinetics of oral ciprofloxacin in 3 continuous cycling peritoneal dialysis (CCPD) outpatients given ciprofloxacin 750 mg b.i.d. for 5 doses was determined. Mean steady-state maximum serum concentration and half-life were 4.4 ± 1.5 mg/L and 10.3 ± 2.6 hours, respectively. Mean maximum dialysate concentration in the daytime long dwell and overnight continuous cycling dwell were 7.4 ± 1.2 mg/L and 3.3 ± 1.2 mg/L, respectively. Oral ciprofloxacin 750 mg b.i.d. may be reasonable for bloodstream and peritoneal infections caused by susceptible bacteria in CCPD patients...

INTRODUCTION: Very early withdrawal from treatment in patients undergoing peritoneal dialysis (PD) is an increasingly important, but poorly understood, issue. Here, we identified the reasons and risk factors for very early withdrawal from PD. METHODS: Incident PD patients from The First Affiliated Hospital of Sun Yat-sen University above 18 years who started treatment between January 1 2006 and December 31 2011 were included. Cessation of PD therapy within the first 90 days after beginning dialysis was classified as very early withdrawal...

BACKGROUND: Hyperthermic intraperitoneal chemotherapy (HIPEC) administration can be associated with hyperglycemia during perfusion. Little is known about this effect, and no previous studies have examined patient characteristics associated with perfusion-related hyperglycemia. METHODS: We retrospectively identified consecutive patients at a single institution treated with HIPEC from 8/2003 to 10/2016 who had intraoperative blood glucose measured. Hypertonic 1.5% dextrose-containing peritoneal dialysate was used as carrier solution in all patients...

INTRODUCTION: Despite the growing number of haemodialysis (HD) patients in India, little is known about vascular access practice. We investigated the use and cost of different vascular accesses by Indian nephrologists. METHODS: An online survey was emailed to 920 Indian nephrologists and 388 (42.1%) responded; 98.5% of whom were responsible for managing dialysis patients, 98% in hospitals. RESULTS: Sixty-four percent of patients initiated renal replacement therapy with HD, 7% with peritoneal dialysis, 10% kidney transplantation and 19% conservative care...

BACKGROUND: Peritoneal dialysis (PD) is well-established as renal replacement therapy in end stage renal disease and has survival rates similar or better than hemodialysis (HD) for the initial years on dialysis therapy. However retention rate is lower due to higher technique failure rates than in HD and few patients stay on PD for more than 10 years (PD>10 yrs). Here we investigated clinical features characterizing PD>10 yrs patients. PATIENTS AND METHODS: In a single center study of 450 prevalent PD patients, 35 PD>10 yrs patients (n=35) were compared with patients (n=415) who had been on PD for shorter periods of time in terms of clinical characteristics...

The role of histone deacetylase 6 (HDAC6) in peritoneal fibrosis remains unknown. In this study, we examined the effect of HDAC6 inhibition on the epithelial-mesenchymal transition (EMT) of peritoneal mesothelial cells and development of peritoneal fibrosis. Treatment with tubastatin A, a highly selective HDAC6 inhibitor, or silencing of HDAC6 with siRNA inhibited transforming growth factor β1-induced EMT, as evidenced by decreased expression of α-smooth muscle actin, collagen I and preserved expression of E-cadherin in cultured human peritoneal mesothelial cells...

Peritoneal dialysis (PD)-associated peritoneal fibrosis is a chronic progress which induces ultrafiltration failure. It remains a challenge to prevent the progression of PD-associated fibrosis in clinic practice. Wnt/β-catenin pathway plays important role in many severe fibrotic diseases, here we investigated its contribution to the development of peritoneal damage. We isolated mesothelial cells (MC) from the effluent of PD patients and found that the expressions of Wnt1, Wnt5a, β-catenin, and LEF1 were increased in patients with more than 1-year PD compared with patients who just started with PD (<1 month)...

Acid-base regulation is essential to maintain homeostasis in humans. Carbonic acid/bicarbonate (H2CO3/HCO3-) couple is the most predominant extracellular buffer to keep plasma pH within a physiological range. The ability to (re)generate such a buffer is a key milestone that necessitates to understand a precise physiology of both renal tubule and digestive tract. Here, we first reviewed renal and digestive cycles of bicarbonate in physiology. We also reviewed pathological findings where acid-base disequilibrium is involved and nutritional and/or alkali therapy could be necessary...

INTRODUCTION: Hemodialysis (HD) is an expensive therapy in economic and in ecological terms, owing to a high carbon footprint and significant consumption of natural sources, especially water. Our aim was to review strategies to diminish waste of water in maintenance dialysis, exploring previously described water reuse trends and less known strategies for reducing the dialysate flow. METHODS: We conducted a systematic review of water-sparing strategies, including the reuse of reverse osmosis rejected water and the reduction of dialysate flux...

Icodextrin is a starch-derived glucose polymer used in peritoneal dialysis dialysate to treat volume overload by increasing ultrafiltration in patients with end-stage renal disease. Reported adverse reactions to icodextrin are mild and rare and mainly consist of skin rash that resolves spontaneously after discontinuation of treatment. We describe a young patient with extreme eosinophilia that appeared with the use of icodextrin, disappeared after its discontinuation, and reappeared after a rechallenge with the drug...

INTRODUCTION: Liposome supported peritoneal dialysis is a recently described technique which may eventually be applicacle in the clinical scenario of the intoxicated patient. We evaluated the hypothesis that intravenous injection lipid emulsion (ILE) would augment acidic pH gradient liposome supported peritoneal dialysis (LSPD). METHODS: Orogastrically amitriptyline dosed rats were treated with either NaHCO3 intravenously and standard intraperitoneal dialysate (A); NaHCO3 intravenously and LSPD (B); or ILE and LSPD (C)...

Despite decades of research, the clinical efficacy of peritoneal dialysis (PD) remains enigmatic. We may wonder why the modality fail in some patients but perhaps the more proper question would be, why it works in so many? We know that the contribution of residual renal function (RRF), more so than in hemodialysis, is critically important to the well-being of many of the patients. Unique features of the modality include the relatively low volume of dialysate fluid needed to provide effective uremic control and the disproportionate tendency for both hypokalemia and hypoalbuminemia, when compared to hemodialysis...

Background: Peritoneal fibrosis, in which inflammation and apoptosis play crucial pathogenic roles, is a severe complication associated with the treatment of kidney failure with peritoneal dialysis (PD) using a glucose-based dialysate. Mesothelial cells (MCs) take part in the inflammatory processes by producing various cytokines and chemokines, such as monocyte chemoattractant protein 1 (MCP-1) and interleukin 8 (IL-8). The apoptosis of MCs induced by high glucose levels also contributes to complications of PD...

The characteristic features of chronic peritoneal injury with peritoneal dialysis (PD) are submesothelial fibrosis and neoangiogenesis. Transforming growth factor (TGF)-β and vascular endothelial growth factor (VEGF)-A are the main mediators of fibrosis and neoangiogenesis, respectively; however, the effect of the interaction between them on the peritoneum is not well known. In this study, we investigated the relationship between TGF-β1 and VEGF-A in inducing peritoneal fibrosis using human tissues and dialysate, cultured cells, and animal models...
