BACKGROUND: Intraperitoneal (IP) administration of ceftazidime is recommended for the treatment of peritoneal dialysis-associated peritonitis (PDAP) from Pseudomonas. Patients with PDAP may also need IP heparin to overcome problems with drainage of turbid peritoneal dialysis (PD) fluids and blockage of catheters with fibrin. Physico-chemical stability of ceftazidime and heparin, and biological stability of heparin in many types of PD solutions is unknown. Therefore, we investigated the stability of ceftazidime and heparin in 4 types of PD solutions...

BACKGROUND/OBJECTIVES: Sarcopenia is associated with increased mortality. European and North American recommended screening for low muscle mass uses gender specific cut points, with no adjustment for ethnicity. We wished to determine whether the prevalence of sarcopenia was altered by ethnicity in peritoneal dialysis (PD) patients. SUBJECTS/METHODS: We measured appendicular lean mass indexed to height (ALMI) in PD patients by segmental bioimpedance and determined sarcopenia using different cut off points for reduced muscle mass...

Icodextrin is a starch derivative used for preparing solutions of peritoneal dialysis. Unfortunately, peptidoglycans (PGN) and lipopolysaccharides (LPS) have been reported to contaminate certain icodextrin batches and to contribute to the development of sterile peritonitis. The decision of selecting or rejecting icodextrin batches is however difficult, because of limitations in the detection of these bacterial contaminants. Besides monocyte activation tests of cytokine release, a number of bio-assays using stably TLR-transfected cell lines have been developed...

Arterial stiffness is an important risk factor for cardiovascular disease (CVD) in patients with end-stage renal failure. However, little is known about the factors that contribute to arterial rigidity in peritoneal dialysis (PD) patients. The aim of this study was to define the pattern and determinants of the longitudinal change in arterial stiffness after PD initiation.Arterial stiffening was estimated for 46 PD patients by using brachial-ankle pulse wave velocity (baPWV) and carotid intima-media thickness (cIMT)...

BACKGROUND: The longitudinal effects of peritoneal dialysis (PD) peritonitis on small solute clearance and ultrafiltration are controversial. MATERIALS AND METHODS: We identified 27 patients with PD peritonitis over a 4-year period at a tertiary hospital. Adequacy tests at an "early" (1 - 3 months), "intermediate" (6 ± 2 months), and a "late" (12 ± 2 months) time period after the episode were compared with a pre-peritonitis baseline. The effect of time on serum albumin, weekly creatinine clearance, Kt/V, and net fluid volume removal was assessed...

The significance of peritoneal dialysis in kidney replacement therapy is expected to increase, so it is important to reconsider glucose exposure to minimize the adverse effects. The first step was to develop biocompatible modern PD solutions to reduce the local and systemic adverse effects of current conventional glucose-based ones. According to the limited clinical experience, there are no clear data on better clinical outcome. Besides this there is a suspected theoretical correlation between development of encapsulating peritoneal sclerosis and chronic local irritation of peritoneal surface by glucose...

BACKGROUND: Starting dialysis at an advanced age is a clinical challenge and an ethical dilemma. The advantages of starting dialysis at "extreme" ages are questionable as high dialysis-related morbidity induces a reflection on the cost- benefit ratio of this demanding and expensive treatment in a person that has a short life expectancy. Where clinical advantages are doubtful, ethical analysis can help us reach decisions and find adapted solutions. CASE PRESENTATION: Mr...

BACKGROUND: Evidence of effective interventions to prevent peritoneal dialysis (PD) catheter malfunction before first use is presently insufficient to guide clinical care. Regular flushing of the PD catheter (e.g. before PD commencement) has been adopted by some practitioners in the belief that it will prevent catheter obstruction and/or malfunction. The aim of this study was to characterize and evaluate PD catheter flushing practices across Australian and New Zealand PD units. METHODS: An on-line survey was distributed to all 62 PD units in Australia (12 August 2016; n = 51) and New Zealand (2 February 2017; n = 11), with questions relating to PD catheter flushing practices, audit, and outcomes...

BACKGROUND: Peritoneal dialysis (PD) is used as renal replacement therapy in patients with end-stage kidney disease. However, peritoneal membrane failure remains problematic and constitutes a critical cause of PD discontinuation. Recent studies have revealed the unique biological action of molecular hydrogen (H2) as an anti-oxidant, which ameliorates tissue injury. In the present study, we aimed to examine the effects of H2 on the peritoneal membrane of experimental PD rats. METHOD: Eight-week-old male Sprague-Dawley rats were divided into the following groups (n = 8-11 each) receiving different test solutions: control group (no treatment), PD group (commercially available lactate-based neutral 2...

Long-term peritoneal dialysis is accompanied by functional and histopathological alterations in the peritoneal membrane. In the long process of peritoneal dialysis, high-glucose peritoneal dialysis solution (HGPDS) will aggravate the peritoneal fibrosis, leading to decreased effectiveness of peritoneal dialysis and ultrafiltration failure. In this study, we found that the coincidence of elevated TGF-β1 expression, autophagy, apoptosis and fibrosis in peritoneal membrane from patients with peritoneal dialysis...

BACKGROUND/AIMS: Enterococcal peritonitis in peritoneal dialysis (PD) patients is associated with a high complication rate. The optimal treatment regimen of PD-related enterococcal peritonitis is controversial. The latest international guideline recommends intra-peritoneal (IP) vancomycin. Although ampicillin is often effective for systemic enterococcal infections, they have little in vitro activity when added to common PD solutions. Since oral amoxicillin achieves therapeutic drug level in the peritoneal cavity, we explore the efficacy of oral amoxicillin for enterococcal peritonitis...

BACKGROUND: Acute pancreatitis can be a life-threatening complication in patients with chronic kidney disease (CKD), especially in kidney transplant recipients. CASE DIAGNOSIS/TREATMENT: The patient was 7 years old when he received renal transplantation for CKD secondary to posterior urethral valves. Two years later, he presented with severe necrotizing pancreatitis (Ranson's score 5, Balthazar's score 8). Viral and genetic testing came back negative; pancreatitis was attributed to the patient's treatments (prednisone, trimethoprim-sulfamethoxazole, and everolimus)...

BACKGROUND: Kidney congestion is a common pathophysiologic pathway of acute kidney injury (AKI) in sepsis and heart failure. There is no noninvasive tool to measure kidney intracapsular pressure (KIP) directly. METHODS: We evaluated the correlation of KIP with kidney elasticity measured by ultrasound surface wave elastography (USWE). We directly measured transcatheter KIP in three pigs at baseline and after bolus infusion of normal saline, norepinephrine, vasopressin, dopamine, and fenoldopam; infiltration of 2-L peritoneal dialysis solution in the intra-abdominal space; and venous, arterial, and ureteral clamping...

Peritoneal dialysis (PD) has been an attractive treatment for end-stage kidney disease. Long-term exposure to the PD solution creates functional and morphological alterations, and these alterations diminish the efficacy of PD. It is important to establish an evaluation of the changes in PD patients and strategies for the prevention of PD damage and encapsulating peritoneal sclerosis (EPS). We determined the relationship between clinical findings and macroscopic morphological findings by laparoscopy in patients receiving PD...

BACKGROUND: Patients on automated peritoneal dialysis (APD) may have greater exposure to glucose in the PD fluid than those on continuous ambulatory PD (CAPD). If this causes long-term damage to the peritoneal membrane, it will have implications for a patient's choice of modality. METHODS: Membrane function of long-term APD or CAPD patients was followed prospectively. The data were collected from electronic patient records in our unit from 2000 to 2014. The rate of change in membrane transport status (D/Pcr) and ultrafiltration (UF4) for each patient was calculated using the least square regression line equation...

Sterilising glucose solutions by heat promotes the generation of a large number of glucose degradation products (GDPs). It has been shown that high levels of GDPs may result in Advanced Glycation End products that have an impact on cellular homeostasis and health in general. If data is available for peritoneal dialysis solutions, little has been published for glucose infusion fluids. It is essential to identify the parameters causing the formation of GDPs and so limit the risk of exposing patients to them. After quantifying both 5-hydroxymethyl-2-furfural, considered as an important indicator of degradation, and 2-furaldehyde, an ultimate GDP of one degradation pathway, in marketed solutions, the aim of this work is to build a model integrating all the parameters involved in the formation rates of these two GDPs: supplier, glucose amount, container material, oxygen permeability coefficient and time-lapse since manufacture...

BACKGROUND: Glucose is widely used as an osmotic agent in peritoneal dialysis (PD), but exerts untoward effects on the peritoneum. The potential protective effect of a reduced exposure to hypertonic glucose has never been investigated. METHODS: The cohort of PD patients attending our center which tackled the challenge of a restricted use of hypertonic glucose solutions has been prospectively followed since 1992. Small-solute transport was assessed using an equivalent of the glucose peritoneal equilibration test after 6 months, and then every year...

Compared to hemodialysis, peritoneal dialysis represents a more straightforward and less invasive alternative, though current solutions are not as effective. Herein, the feasibility of liposome-supported enzymatic peritoneal dialysis (LSEPD) is explored to increase the functionality of peritoneal dialysis for the model indication acute alcohol poisoning. Enzyme-loaded liposomes (E-Liposomes) containing alcohol metabolizing enzymes, alcohol oxidase and catalase, are developed and their in vitro and in vivo performances investigated...
