BACKGROUND: Bicarbonate-based peritoneal dialysis (PD) fluids enhance the migratory capacity and damage-repair ability of human peritoneal mesothelial cells by upregulating AQP1. However, little is known about the underlying molecular mechanisms. RESULTS: Here we used HEK-293T cells to investigate the effect of pH on AQP1 gene transcription levels. We found that AQP1 mRNA levels increases with pH. Transfection of HEK-293T cells with luciferase reporter vectors containing different regions of the AQP1 promoter identified an upstream region in the AQP1 gene between - 2200 and - 2300 bp as an enhancer required for pH-mediated regulation of AQP1 expression...

BACKGROUND: Renal transplant (RTX) recipients seem to experience a better quality of life compared to dialysis patients. However, the factors responsible for this positive effect are not completely defined. Conceivably, a change in the physical performance of these patients could play a role. METHODS: To assess this, we measured: (1) waist circumference, fat mass and appendicular fat-free mass (aFFM) by dual-energy X-ray densitometry, (2) physical performance with the Short Physical Performance Battery, and (3) muscle strength with the handgrip test, in 59 male RTX, 11 chronic kidney disease in conservative treatment (CKD) and 10 peritoneal dialysis (PD) patients...

PURPOSE: The early period after chronic kidney disease (CKD) patients transition to end-stage renal disease (ESRD) represents the highest mortality risk but is variable among different patient populations and clinical circumstances. We compared early mortality outcomes among a diverse CKD population that transitioned to ESRD. METHODS: A retrospective cohort study (1/1/2002 through 12/31/2013) of CKD patients (age ≥ 18 years) who transitioned to peritoneal dialysis (PD), hemodialysis (HD) with arteriovenous fistula/grafts, and HD with catheters was performed...

The aim of this study was to measure insulin resistance (IR) in dialysis patients and its relation to Vitamin D status and nutritional parameters. We included patients on maintenance dialysis, both hemodialysis and peritoneal dialysis (HD and PD). IR was measured by homeostatic model assessment (HOMA)-IR index defined as fasting serum insulin (μU/L) × fasting blood sugar (mmol/L)/22.5. Baseline Vitamin D levels were measured by chemiluminescence immunoassay (CLIA) method. HOMA-IR index correlated with nutritional parameters such as 7-point subjective global assessment (SGA) and anthropometric measures, for example, body fat percentage, lean body weight (LBW), mid-arm circumference (MAC), and mid-arm muscle circumference (MAMC)...

Delayed visceral organ perforations after PD catheter insertions are extremely rare. We report two patients who presented with asymptomatic visceral perforation from their buried PD catheters. Five months after a laparoscopic buried PD catheter insertion in a 92-year-old man PD was initiated; bile and bowel contents were noted in the PD effluent. He subsequently expired (from pneumonia) to autopsy revealed the PD catheter within the small bowel. Despite this perforation, there was no evidence of peritonitis, inflammation, nor any bowel content within the peritoneal cavity...

The effect of dyslipidemia on peritoneal dialysis (PD) patients based on the presence of residual renal function (RRF; renal creatinine clearance >2 mL/min/1.73 m²) is unknown. Data from the Taiwan Renal Registry Data System between 2005 and 2012 were analyzed to estimate the association between dyslipidemia and mortality in PD patients. Long-term PD patients ( n = 8032) were divided into groups with (RRF; n = 2691, 33.5%) and without RRF (non-RRF; n = 5341, 66.5%). The primary outcome was three-year mortality, and multivariate Cox regression was used for survival analysis...

BACKGROUND: Peritonitis, which is one of the leading complications of peritoneal dialysis (PD) worldwide, severely affected morbidity and mortality of the PD patients. Although many efforts have been made to prevent PD-related peritonitis, it seems impossible to prevent it completely. Many causes have been reported to lead to peritonitis, and contamination during bag exchange is one of the important risk factors for peritonitis. METHODS: Here, we introduce an operating vehicle, which we invented to provide a sterile and safe space for bag exchange...

Technique failure is a frequent complication of peritoneal dialysis (PD), but the association between causes of death-censored technique failure and mortality remains unclear. Using Australian and New Zealand Dialysis and Transplant (ANZDATA) registry data, we examined the associations between technique failure causes and mortality in all incident PD patients who experienced technique failure between 1989-2014. Of 4663 patients, 2415 experienced technique failure attributed to infection, 883 to inadequate dialysis, 836 to mechanical failure and 529 to social reasons...

We found previously that altering macrophage polarization toward M2 responses by injection of colony stimulating factor-1 (CSF-1) was more effective in reducing both primary and latent infection in HSV-1 ocularly infected mice than M1 polarization by IFN-γ injection. Cytokines can coordinately regulate macrophage and TH responses, with IL-4 inducing TH 2 as well as M2 responses and IFN-γ inducing TH 1 as well as M1 responses. We have now differentiated the contributions of these immune compartments on protection against latency/reactivation and corneal scarring by comparing the effects of infection with recombinant HSV-1 in which the latency associated transcript (LAT) gene was replaced with either the IL-4 (HSV-IL-4) or IFN-γ (HSV-IFN-γ) genes using infection with the parental (LAT-negative) virus as a control...

PURPOSE: Icodextrin can enhance ultrafiltration and consequently improve fluid balance and can control blood pressure and reduce left ventricular mass for peritoneal dialysis (PD) patients. This study investigated whether icodextrin use could reduce the risk of congestive heart failure (CHF) for PD patients. METHODS: From the Taiwan National Health Insurance database, we identified 5462 newly diagnosed end-stage renal disease patients undergoing PD from 2005 to 2010...

BACKGROUND: Peritoneal dialysis (PD) is one of the corner stones of renal replacement therapy and should be strongly considered if preemptive kidney transplantation is not available. SUMMARY: There are several initiatives that may help the growth in the use of PD around the world. First, PD is an underused and valuable option in patients with heart failure and the chronic cardiorenal syndrome, especially in those with frequent hospitalizations despite optimal medical therapy...

BACKGROUND: Dialysis patients have an exceedingly high mortality rate. Biomarkers may be useful tools in risk stratification of this population. We evaluated the prognostic value of high-sensitivity cardiac troponin T (hs-cTnT) and CRP (C-reactive protein) in predicting adverse outcomes in stable hemodialysis and peritoneal dialysis (PD) patients. Variability in hs-cTnT was also examined. METHODS AND RESULTS: A retrospective cohort study included 574 dialysis patients (hemodialysis 347, PD 227)...

In vitro biocompatibility assessments that consider physiologically appropriate conditions of cell exposure to peritoneal dialysis fluids (PDFs) are still awaited. In this study, we found that fragmentation of Golgi apparatus occurred in a pH-dependent manner within 30-min exposure to five distinct commercially available PDFs, which showed no marked difference in their effects on cell viability in the conventional MTT assay. Fluorescence microscopy analysis of labeling antibody against cis-Golgi protein GM130 indicated that the stacked cisternal structure was maintained in the perinuclear area of both M199 culture medium and a neutral-pH PDF groups...
