    The purpose of this study was to evaluate the efficacy, complications, and mortality rate associated with acute peritoneal dialysis (PD) in patients with acute kidney injury (AKI). A total of 75 patients who were treated at Samsung Changwon Hospital between February 2005 and March 2016 were included in the study sample. The outcomes included in-hospital survival, renal recovery, metabolic and fluid control rates, and technical success rates. Refractory heart failure was the most frequent cause of acute PD (49.3%), followed by hepatic failure (20.0%), septic shock (14.7%), acute pancreatitis (9.3%), and unknown causes (6.7%). The hospital survival of patients in the acute PD was 48.0%. Etiologies of acute kidney injury (AKI) (refractory heart failure, acute pancreatitis compared with hepatic failure, septic shock or miscellaneous causes), use of inotropes, use of a ventilator, and simplified acute physiology score (SAPS) II were associated with survival differences. Maintenance dialysis required after survival was high (80.1% [29/36]) due to AKI etiologies (heart or hepatic failures). Metabolic and fluid control rates were 77.3%. The technical success rate for acute PD was 93.3%. Acute PD remains a suitable treatment modality for patients with AKI in the era of continuous renal replacement therapy (CRRT). Nearly all patients who require dialysis can be dialyzed with acute PD without mechanical difficulties. This is particularly true in patients with refractory heart failure and acute pancreatitis who had a weak requirement for inotropes. Copyright © 2017 International Society for Peritoneal Dialysis.

    Peritoneal dialysis is becoming more important in the management of patients with end-stage renal disease. Because of the efforts of the “Fistula First Breakthrough Initiative,” dialysis venous access in the United States has become focused on promoting arteriovenous fistula creation and reducing the number of patients who start dialysis with a tunneled catheter. This is important because tunneled catheters can lead to infection, endocarditis, and early loss of more long-term access. When planned for, peritoneal dialysis can offer patients the opportunity to start dialysis at home without jeopardizing central access or the possibilities of eventual arteriovenous fistula creation. The purpose of this review is to highlight the indications, contraindications, and procedural methods for implanting peritoneal dialysis catheters in the interventional radiology suite.

    The clinical benefits of using icodextrin during acute peritonitis in peritoneal dialysis are uncertain. On the premise that high glucose concentration might jeopardize the peritoneal defense during peritonitis, icodextrin administration during acute peritonitis could have the potential to improve the peritonitis outcome whilst improving ultrafiltration. We conducted a single-center, open-label, randomized controlled trial in which 53 adult continuous ambulatory peritoneal dialysis patients underwent randomization to receive either icodextrin or original glucose-based dialysis solution. The primary outcome measure was the peritoneal dialyzate white cell count on Day 3. Secondary outcome measures comprised the need of additional hypertonic exchanges, fluid control as denoted by changes in body weight, and the clinical outcome of peritonitis including 30-day and 120-day all-cause mortality. Between icodextrin and control treatment groups, there were no statistically significant differences in the peritoneal dialyzate white cell count on day (1829 versus 987/mm(3), P = 0.13). There was neither improvement in primary cure rate (31.8 versus 32.3%, P = 1.00), nor was there any change in 120-day mortality after icodextrin use (13.6 versus 12.9%, P = 1.00). However, requirement of hypertonic dialysis exchange was much more frequent in the control group than in those randomized to icodextrin (35.5 versus 0%, P = 0.001). Body weight did not change significantly in the icodextrin group, but body weight in the control group increased from 63.3 ± 14.5 kg at baseline to 64.2 ± 14.2 kg at Day 5 (P = 0.0002) and 65.2 ± 14.1 kg at Day 10 (P < 0.0001). As compared with glucose-based peritoneal dialysis solution, use of icodextrin achieved better ultrafiltration and fluid control during acute peritonitis complicating continuous ambulatory peritoneal dialysis, although we found no evidence of a worthwhile clinical benefit on peritonitis resolution.

    The impact of dialysis modality on outcome, especially on infection early in the course of dialysis, in unplanned acute dialysis initiation has not been well evaluated. The aim of the study was to compare the rates and causes of mortality and morbidity in incident dialysis patients started unplanned acute peritoneal dialysis (PD) or haemodialysis (HD). In this observational cohort study, incident dialysis patients with initiation of unplanned and acute PD (n = 66) or HD (n = 57) at a single centre from March 2005 to June 2010 were included and followed up for 6 months (0-183 days, mean follow-up time 4.72 months). For PD, surgically placed Tenckhoff catheters were used. All HD patients were dialysed with a central venous catheter (non-tunnelled or tunnelled). There were no significant differences in terms of gender, age and prevalence of diabetes mellitus in either group. The prevalence of heart failure [New York Heart Association (NYHA) Stage III-IV] was significantly higher in the PD group (73 versus 46% in HD group, P < 0.01). The population was stratified to PD and HD comparing mortality, infection, bacteraemia and hospitalization. Of the 123 patients who commenced acute and unplanned dialysis, n = 44 (35.8%) died during the follow-up period of 0-183 days. There were no significant difference in half-year mortality in n = 20 PD patients (30.3%) versus n = 24 HD patients (42.1%) (P = 0.19). The cardiovascular mortality in PD and HD patients were 9.1 and 10.5%, respectively (P = 1.00). Overall mortality due to infection was higher in the HD (17.5%) versus in the PD group (9.1%), however, not significant (P = 0.19). HD patients had significantly higher probability of bacteraemia in the first 183 days compared to PD patients (21.1 versus 3.0%, P < 0.01). Group comparison by Poisson regression analyses showed that the relative risk of bacteraemia in the PD group versus HD group was 0.16 (95% confidence interval, 0.05-0.57, P = 0.005). The significant difference was

    The high mortality rate among critically ill patients with acute kidney injury (AKI) remains an unsolved problem in intensive care medicine, despite the use of renal replacement therapy (RRT). Increasing evidence from clinical studies in adults and children suggests that the new peritoneal dialysis (PD) fluids may allow for better long-term preservation of peritoneal morphology and function. Formation of glucose degradation products (GDPs) can be reduced and even avoided with the use of newer "biocompatible" solutions. However, it is still unclear if there are any differences in using conventional (lactate) solutions compared with low GDP (bicarbonate) solutions for acute PD. To look at the benefits and harms of bicarbonate versus lactate solutions in acute PD. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (from 1966), EMBASE (from 1980), Latin American and Caribbean Health Sciences Literature Database LILACS (from 1982), and reference lists of articles.Date of last search: 6 May 2014. Randomised controlled trials (RCTs) comparing bicarbonate to lactate solution for acute PD. Two authors independently assess the methodological quality of studies. One author abstracted data onto a standard form, and a second author checked data extraction. We used the random-effects model and expressed the results as relative risk (RR) for dichotomous outcomes and mean difference (MD) for continuous outcomes with 95% confidence intervals (CI). We included one study (20 patients) in this review. In shock patients, bicarbonate did not differ from lactate with respect to mortality (RR 0.50, 95% CI 0.06 to 3.91); however there were significant differences in blood lactate (MD -1.60 mmol/L, 95% CI -2.04 to -1.16), serum bicarbonate (MD 5.00 mmol/L, 95% CI 3.26 to 6.74) and blood pH (MD 0.12, 95% CI 0.06 to 0.18). In non-shock patients there was a significance difference in blood lactate (MD -0.60 mmol/L, 95% CI -0.85 to -0.35) but not in serum

    Hemolytic uremic syndrome (HUS) is a leading cause of acute renal failure (ARF) in children, and one for which treatment with peritoneal dialysis (PD) is often necessary. Between January 1982 and December 1996, 176 children received PD for ARF at St. Christopher's Hospital for Children; 34 (19%) of whom had HUS. Of these 34, 7 (20%) developed pleural effusions (PE) while receiving PD, whereas none of the remaining 142 children with other causes of ARF did so. The mean age of the 7 affected children was 5.2 (range 0.4-17) years; none had heart failure or nephrotic syndrome, nor had any of them undergone thoracic surgery. PE were diagnosed by chest radiograph at an interval of 2 (range 1-3) days after starting PD. Thereafter, 4 (57%) patients were successfully maintained on a modified PD prescription; 2 others were converted to hemodialysis and 1 to continuous venovenous hemodiafiltration. Although PE are a known complication of PD, none of the patients so treated for non-HUS related ARF developed them. Whether they represent a purely mechanical complication of PD, or are in some way attributable to HUS itself, is not entirely clear. Regardless, when children with HUS require PD, physicians should monitor for the development of this potential complication to minimize the risk of serious respiratory compromise.

    Acute peritoneal dialysis (PD) is the preferred therapy for renal replacement in children with post-diarrheal hemolytic uremic syndrome (D+ HUS), but peritonitis remains a frequent complication of this procedure. We reviewed data from 149 patients with D+ HUS who had undergone acute PD with the aim of determining the prevalence and risk factors for the development of peritonitis. A total of 36 patients (24.2%) presented peritonitis. The median onset of peritonitis manifestations was 6 (range 2-18) days after the initiation of dialysis treatment, and Gram-positive microorganisms were the predominant bacterial type isolated (15/36 patients). The patients were divided into two groups: with or without peritonitis, respectively. Univariate analysis revealed that a longer duration of the oligoanuric period, more days of dialysis, catheter replacement, stay in the intensive care unit, and hypoalbuminemia were significantly associated to the development of peritonitis. The multivariate analysis, controlled by duration of PD, identified the following independent risk factors for peritonitis: catheter replacement [p = 0.037, odds ratio (OR) 1.33, 95% confidence interval (CI) 1.02-1.73], stay in intensive care unit (p = 0.0001, OR 2.62, 95% CI 1.65-4.19), and hypoalbuminemia (p = 0.0076, OR 1.45, 95% CI 1.10-1.91). Based on these findings, we conclude that the optimization of the aseptic technique during catheter manipulation and early nutritional support are targets for the prevention of peritonitis, especially in critically ill patients.

    Severe falciparum malaria complicated by acute renal failure resulted in very high mortality. Ten patients with acute renal failure from falciparum malaria (infected rbc up to 80%) were continuously dialysed using Tenckhoff peritoneal catheter. Five were oliguric and BUN was maintained between 60 to 80 mg/dl (21.4 to 28.6 mmol/l) by hourly 1 to 1.5 liter dialysate exchange during the acute phase. The peritoneal urea clearance (mean +/- SD) was 12.1 +/- 1.2 ml/min with urea nitrogen removal of 13.4 +/- 2.3 g/day. In nonoliguric cases dialysis was also needed for additional removal of waste products since the remaining renal function could not cope with the hypercatabolic state. Peritoneal glucose absorption (135 to 565 g/day) gave considerable caloric supply without volume load and also contributed to the prevention of hypoglycemia. Varying degree of acute respiratory failure developed in all patients with 5 cases (2 oliguric and 3 nonoliguric) progressing to pulmonary edema. Swan-Ganz catheterization and hemodynamic study suggested the role of increased capillary permeability and volume overload from endogenous water formation in the development of pulmonary complication. Continuous removal of fluid and waste products minimized these problems and may prevent the progression of respiratory failure. One patient died of severe sepsis and the other nine survived. This study showed the beneficial contribution of continuous peritoneal dialysis in the management of acute renal failure from severe falciparum malaria.

    Edema is a cardinal feature of the nephrotic syndrome and sometimes merits independent treatment. The use of diuretics is usually sufficient in the treatment of edema. Ultrafiltration (UF) may sometimes be needed in diuretic-resistant states. The use of UF for steroid-resistant nephrotic edema is scarce in children. We report a child with steroid-resistant nephrotic syndrome with diuretic-resistant nephrotic edema treated successfully using acute peritoneal dialysis as a means of UF.

    Abdominal pain with a discoloured dialysate in a patient on peritoneal dialysis (PD) is usually attributed to infective peritonitis. Although acute pancreatitis (AP) is not usually a complication of end-stage renal disease, some studies suggest an increased risk especially in patients on PD. We report a case of idiopathic AP in a 41-year-old female on PD who presented with abdominal pain, fever, vomiting and a clear dark dialysate. Initial diagnosis of PD-associated infective peritonitis was made but dialysate cultures proved negative. Serum amylase showed a mild rise and computed tomography revealed necrotising pancreatitis. No common risk factors for AP were identified and she was successfully treated with conservative therapy. A literature review was carried out using a PubMed search with the words 'acute pancreatitis and peritoneal dialysis'. The literature search found a total of 94 cases of AP in the setting of PD. In more than a quarter, no cause for AP was found. Serum amylase was normal in 12.8% of episodes. Complications developed in 25 cases, and 28 patients died from the condition. Therefore, AP can be a rare, but serious complication of PD with a high mortality and must be considered in the differential diagnosis of abdominal pain in a PD patient.

    The prevalence of acute renal failure (ARF) in obstetric patients in our country is estimated to be between 3 and 42.8%. The most important causes are preeclampsia, especially when associated with thrombotic microangiopathy and hemolysis and less frequently to hemorrhagic shock. Early peritoneal dialysis (EPD) is the temporary treatment. For these patients, 100 % recovery in renal function was observed. When ARF is associated with multiple organ failure (MOF), the reported mortality ranges between 0 and 20 %. To describe clinical features and medical outcomes of patients treated with early peritoneal dialysis in pregnancy complicated by ARF. A case series was conducted at the Research Unit of the Instituto Materno Infantil del Estado de México. We reviewed the cases of patients admitted to the ICU matching the criteria for ARF. They were divided into two groups: those who received EPD vs. those who did not require EPD. The most important national series were included describing the association with preeclampsia and thrombotic microangiopathy with hemolysis. In a 5-year period, 1272 patients were admitted to the ICU; in 38 patients ARF was documented requiring peritoneal dialysis. In nine cases ARF was associated with thrombotic microangiopathy with hemolysis, two cases of stillbirth, and one case of mortality with MOF. A 100% recovery in renal function was observed in all cases, using 1.5% solution with an average of 34 dialysis treatments. The early use of peritoneal dialysis in obstetric patients with ARF has a good prognosis.

  14. Acute inflammation in peritoneal dialysis: experimental studies in rats. Characterization of regulatory mechanisms.

    The predominant problems associated with peritoneal dialysis (PD) are ultrafiltration failure and peritonitis. PD maintains a state of intraperitoneal inflammation that affects the structure and function of the peritoneal membrane, potentially impairing ultrafiltration efficiency. Paradoxically, some PD fluids also have anti-inflammatory properties that may compromise the immune defense against peritonitis. This anti-inflammatory feature is mostly due to the glucose degradation products (GDPs), formed during heat-sterilization and storage of PD fluids. The main purpose of the present thesis was to study regulatory mechanisms behind the acute intraperitoneal inflammatory response in PD in the presence and absence of experimental peritonitis. Rats were exposed to a single dose of heat- or filter sterilized PD fluids either as an i.p. injection or as an infusion through an indwelling catheter, with or without supplementations, or pretreatment of the animals. The dwell fluid was analyzed zero, two and four hours later concerning activation of the complement and coagulation cascades, neutrophil recruitment and respiratory burst, ultrafiltration volumes, cytokine-induced neutrophil chemoattractant (CINC-1), rat mast cell protease 2 (RMCP-2), glucose, urea and histamine concentrations and ex vivo/in vitro intraperitoneal chemotactic activity. Exposure to filter sterilized PD fluid alone induced intraperitoneal complement activation and coagulation, neutrophil recruitment and increased the levels of CINC-1 during the dwell. Intraperitoneal concentrations of the mast cell markers histamine and RMCP-2 changed little during the dwells and did not indicate mast cell activation. Low molecular weight heparin (LMWH) and C5 blockade improved ultrafiltration. Pretreatment with cobra venom factor, known decomplementing agent, blocked the CINC-1 release and the neutrophil recruitment and improved ultrafiltration. In combination with experimental peritonitis, heat sterilized PD fluid

All children under the age of 15 years, who had either peritoneal dialysis or haemodialysis for acute kidney injury in Aminu Kano Teaching Hospital over a 1-year period, were studied. The average cost of each dialysis modality was estimated. Of 20 children, who had dialysis for acute kidney injury, 12 (60%) had haemodialysis and 8 (40%) had peritoneal dialysis. The mean cost for haemodialysis exceeded that of peritoneal dialysis ($363.33 vs. $311.66, t = 1.04, P = 0.313) with the mean cost of consumables significantly accounting for most of the cost variation ($248.49 vs. $164.73, t = 2.91, P = 0.009). Mean costs of nephrologist visit and nursing were not found to be significant.

    The 7.5% icodextrin solution is widely used for long-dwell in peritoneal dialysis (PD) regimens as an alternative osmotic agent to glucose. It has been defined as a biocompatible agent because of its iso-osmolarity and is generally safe and well tolerated. Icodextrin and its hydrolyzed metabolites are found in systemic circulation. In serum, icodextrin interferes with amylase determination causing a significantly decreased plasma amylase level making it unreliable for the diagnosis of acute pancreatitis. Lipase measurement provides an alternative and accurate method for diagnosing acute pancreatitis (AP) in patients using icodextrin. Icodextrin-induced acute pancreatitis is not well described. The literature appears limited to two case reports. We describe a case of a man with end-stage renal disease (ESRD) on PD who developed acute pancreatitis following icodextrin use. We also provide a novel possible mechanism for understanding how icodextrin causes AP.

    Summary Background and objectives Acute renal failure can be treated with different dialysis modalities, depending on patient characteristics and hospital resources. Peritoneal dialysis (PD) can be first choice in situations like hypotension, disturbed coagulation, or difficult venous access. The main disadvantage of PD is the relatively limited efficacy. The aim of this study was to investigate whether continuous flow peritoneal dialysis (CFPD) is a more effective treatment than conventional PD in acute renal failure. Design, setting, participants, & measurements A pilot study was performed at The Red Cross University Hospital in Cape Town in six patients. Patients were treated with both CFPD and conventional PD for 8 to 16 hours. CFPD was performed with two bedside-placed catheters. After initial filling, dialysate flow rate (100 ml/1.73 m2 per minute) was maintained with an adapted continuous venovenous hemofiltration machine. Ultrafiltration flow rate was set at 2.5 ml/1.73 m2 per minute. Results Mean ultrafiltration was 0.20 ml/1.73 m2 per minute with conventional PD versus 1.8 ml/1.73 m2 per minute with CFPD. Mean clearances of urea and creatinine were 5.0 and 7.6 ml/1.73 m2 per minute with conventional PD versus 15.0 and 28.8 ml/1.73 m2 per minute with CFPD, respectively. No complications occurred. Conclusions In this first report of CFPD in six pediatric patients with acute renal failure, CFPD was on average three to five times more effective for urea and creatinine clearance and ultrafiltration than conventional PD, without any complications observed. CFPD has the ability to improve therapy for acute renal failure . PMID:21030578

  18. Peritoneal Dialysis in Renal Replacement Therapy for Patients with Acute Kidney Injury

    2011-01-01

    Peritoneal dialysis (PD) was the first modality used for renal replacement therapy (RRT) of patients with acute kidney injury (AKI) because of its inherent advantages as compared to Hemodialysis. It provides the nephrologist with nonvascular alternative for renal replacement therapy. It is an inexpensive modality in developing countries and does not require highly trained staff or a complex apparatus. Systemic anticoagulation is not needed, and it can be easily initiated. It can be used as continuous or intermittent procedure and, due to slow fluid and solute removal, helps maintain hemodynamic stability especially in patients admitted to the intensive care unit. PD has been successfully used in AKI involving patients with hemodynamic instability, those at risk of bleeding, and infants and children with AKI or circulatory failure. Newer continuous renal replacement therapies (CRRTs) are being increasingly used in renal replacement therapy of AKI with less use of PD. Results of studies comparing newer modalities of CRRT versus acute peritoneal dialysis have been conflicting. PD is the modality of choice in renal replacement therapy in pediatric patients and in patients with AKI in developing countries. PMID:21716704

    During the 1970s and 1980s, peritoneal dialysis (PD) was widely accepted as the standard treatment for acute kidney injury (AKI). However, advances in the techniques of extracorporeal blood purification gradually reduced its use, making PD an underused modality in this context. Although PD for AKI is an underutilized modality worldwide, it is frequently used in developing countries because of its lower cost and minimal infrastructure requirements. Recent studies have shown that PD administered continuously through a flexible catheter and cycler is an effective treatment in AKI because it ensures adequate fluid status and metabolic control. However, the use of PD in AKI has several limitations, such as the need for an intact peritoneal cavity and, in emergency situations such as severe fluid overload and severe hyperkalemia, an efficacy that is lower than that with extracorporeal blood purification techniques. Metabolic, infectious, and mechanical disorders related to PD are also limitations.Among the metabolic complications of PD are hyperglycemia, hypernatremia, protein loss into the dialysate, and hypercatabolism. Hyperglycemia is caused by the use of dialysate containing high concentrations of glucose. Hypernatremia is a result of short dialysate dwell times during the rapid exchanges of high-volume PD. Protein loss into the dialysate can reach 48 g daily, worsening the nutrition status of patients already depleted by AKI. Severe hypercatabolism caused by PD remains controversial and occurs because PD methods cannot provide an adequate dialysis dose for AKI patients.Few studies have assessed the metabolic implications of PD in AKI patients. Evaluation of these implications is relatively simple, imposes no additional costs, and can provide information about the severity of the disease. Evaluation could also guide the selection of therapeutic, dialytic, and nutrition measures, preventing metabolic complications. The present manuscript describes the metabolic

    Peritoneal lavage and dialysis is an approach to treat necrotizing acute pancreatitis as it removes dialyzable toxins and reduces severe metabolic disturbances. Successful catheter implantation is important for delivering adequate peritoneal lavage and dialysis. The aim of the present study was to describe a new modified percutaneous technique for the placement of peritoneal dialysis catheters and assess the effectiveness and safety of peritoneal lavage and dialysis used for treatment of necrotizing acute pancreatitis. We conducted a retrospective data review of 35 patients of necrotizing acute pancreatitis from January 2010 to December 2014 in Jilin City Central Hospital and The First Affiliated Hospital of ZheJiang University. In total, 18 patients underwent peritoneal lavage and dialysis after inserting catheters by our new technique (group A), whereas 17 patients underwent ultrasound-guided percutaneous catheter drainage (group B). By analyzing the patients' data, the drainage days and mean number of hours between the debut of the symptoms and the hospital admission were lower in group A (P < 0.05, P < 0.05, respectively). The complication rate of 5.6 and 17.6%, respectively (P = 0.261), and a mortality rate of 16.7 and 5.9% for each group, respectively (P = 0.316). Likewise, hospitalization time was similar for the group A: 31 ± 25.3 days compared with 42.8 ± 29.4 days in the group B (P = 0.211). Peritoneal lavage and dialysis can be used in necrotizing acute pancreatitis, and our new modified percutaneous technique offers the same complication and mortality rate as ultrasound-guided drainage but with a shorter drainage days.

    To determine the effect of dialysate osmolarity on peritoneal dialysis drug transfer, peritoneal dialysis clearances of theophylline, phenobarbital, and tobramycin were determined in 10 rabbits using dialysate containing 1.5 and 4.25% glucose. Urea and creatinine clearances were also obtained for comparison. Under similar dialysis conditions, the peritoneal clearances of the three drugs remained unchanged for the two types of dialysate. In contrast, the peritoneal clearances of urea and creatinine were significantly higher with the use of 4.25% glucose dialysate (p less than 0.001). Thus, peritoneal dialysis clearances of theophylline, phenobarbital and tobramycin are not significantly affected by hypertonicity-induced ultrafiltration during acute peritoneal dialysis.

    Acute renal failure (ARF) in adults in the intensive care unit (ICU) often evolves in a context of multiple organ failure, which explains the high mortality rate and increase treatment needs. Among, two modalities of renal replacement therapy, peritoneal dialysis (PD) was the first modality used for the treatment of ARF in the 1950s. Today, while PD is generalized for chronic renal failure treatment, its use in the ICU is limited, particularly, due to the advent of new hemodialysis techniques and the development of continuous replacement therapy. Recently, a renewed interest in the use of PD in patients with ARF has manifested in several emerging countries (Brazil, Vietnam). A systematic review in 2013 showed a similar mortality in ARF patients having PD (58%) and those treated by hemodialysis or hemodiafiltration/hemofiltration (56.1%). In the International society of peritoneal dialysis (ISPD)'s guideline (2013), PD may be used in adult ARF as the other blood extracorporeal epuration technics (recommendation with grade 1B). PD is the preferred method in cardiorenal syndromes, in frailty patients with hemodynamic instability and those lacking vascular access; finally PD is also an option in elderly and patients with bleeding tendency. In industrial countries, high volume automated PD with a flexible catheter (usually Tenckhoff) is advocated. Copyright © 2016 Association Société de néphrologie. Published by Elsevier SAS.

  3. Overcoming the Underutilisation of Peritoneal Dialysis

    Peritoneal dialysis is troubled with declining utilisation as a form of renal replacement therapy in developed countries. We review key aspects of therapy evidenced to have a potential to increase its utilisation. The best evidence to repopulate PD programmes is provided for the positive impact of timely referral and systematic and motivational predialysis education: average odds ratio for instituting peritoneal dialysis versus haemodialysis was 2.6 across several retrospective studies on the impact of predialysis education. Utilisation of PD for unplanned acute dialysis starts facilitated by implantation of peritoneal catheters by interventional nephrologists may diminish the vast predominance of haemodialysis done by central venous catheters for unplanned dialysis start. Assisted peritoneal dialysis can improve accessibility of home based dialysis to elderly, frail, and dependant patients, whose quality of life on replacement therapy may benefit most from dialysis performed at home. Peritoneal dialysis providers should perform close monitoring, preventing measures, and timely prophylactic therapy in patients judged to be prone to EPS development. Each peritoneal dialysis programme should regularly monitor, report, and act on key quality indicators to manifest its ability of constant quality improvement and elevate the confidence of interested patients and financing bodies in the programme.

    Worldwide, there is a steady incident rate of patients with end-stage kidney disease (ESKD) who require renal replacement therapy. Of these patients, approximately one-third have an "unplanned" or "urgent" start to dialysis. This can be a very challenging situation where patients have either not had adequate time for education and decision making regarding dialysis modality and appropriate dialysis access, or a decision was made and plans were altered due to unforeseen circumstances. Despite such unplanned starts, clinicians must still consider the patient's ESKD "life-plan", which includes the best initial dialysis modality and access to suit the patient's individual goals and their medical, social, logistic, and facility circumstances. This paper will discuss the considerations of peritoneal dialysis and a peritoneal dialysis catheter access and hemodialysis and central venous catheter access in patients who require an urgent start to dialysis.

    Aluminum phosphide poisoning is common in our region. It can cause severe metabolic acidosis and persistent hypotension, which lead to cardiogenic shock and subsequently mortality. Oliguric or anuric acute kidney injury is seen in almost all patients with aluminum phosphide poisoning. Renal replacement therapies are recommended in these patients to improve metabolic acidosis and increase the rate of survival. We report 2 cases of severe acute aluminum phosphide poisoning treated successfully with peritoneal dialysis.

    A number of attempts to create a commonly accepted terminology regarding definitions and terms used for clinical entities, methods, problems, and materials encountered by health professionals involved in peritoneal dialysis (PD) were undertaken in the past, the last one in 1990. Later on, some relevant sporadic attempts in a number of textbooks have been made, but they did not include the whole spectrum of PD. This glossary is an attempt to address the need for a universally accepted PD terminology including the latest advances in PD connection systems and fluids.

  7. Approach to the Metabolic Implications of Peritoneal Dialysis in Acute Kidney Injury

    During the 1970s and 1980s, peritoneal dialysis (PD) was widely accepted as the standard treatment for acute kidney injury (AKI). However, advances in the techniques of extracorporeal blood purification gradually reduced its use, making PD an underused modality in this context. Although PD for AKI is an underutilized modality worldwide, it is frequently used in developing countries because of its lower cost and minimal infrastructure requirements. Recent studies have shown that PD administered continuously through a flexible catheter and cycler is an effective treatment in AKI because it ensures adequate fluid status and metabolic control. However, the use of PD in AKI has several limitations, such as the need for an intact peritoneal cavity and, in emergency situations such as severe fluid overload and severe hyperkalemia, an efficacy that is lower than that with extracorporeal blood purification techniques. Metabolic, infectious, and mechanical disorders related to PD are also limitations. Among the metabolic complications of PD are hyperglycemia, hypernatremia, protein loss into the dialysate, and hypercatabolism. Hyperglycemia is caused by the use of dialysate containing high concentrations of glucose. Hypernatremia is a result of short dialysate dwell times during the rapid exchanges of high-volume PD. Protein loss into the dialysate can reach 48 g daily, worsening the nutrition status of patients already depleted by AKI. Severe hypercatabolism caused by PD remains controversial and occurs because PD methods cannot provide an adequate dialysis dose for AKI patients. Few studies have assessed the metabolic implications of PD in AKI patients. Evaluation of these implications is relatively simple, imposes no additional costs, and can provide information about the severity of the disease. Evaluation could also guide the selection of therapeutic, dialytic, and nutrition measures, preventing metabolic complications. The present manuscript describes the metabolic

    Although dialysis has been used in the care of patients with acute kidney injury (AKI) for over 50 years, very little is known about the potential benefits of uremic control on systemic complications of AKI. Since the mortality of AKI requiring renal replacement therapy (RRT) is greater than half in the intensive care unit, a better understanding of the potential of RRT to improve outcomes is urgently needed. Therefore, we sought to develop a technically feasible and reproducible model of RRT in a mouse model of AKI. Models of low- and high-dose peritoneal dialysis (PD) were developed and their effect on AKI, systemic inflammation, and lung injury after ischemic AKI was examined. High-dose PD had no effect on AKI, but effectively cleared serum IL-6, and dramatically reduced lung inflammation, while low-dose PD had no effect on any of these three outcomes. Both models of RRT using PD in AKI in mice reliably lowered urea in a dose-dependent fashion. Thus, use of these models of PD in mice with AKI has great potential to unravel the mechanisms by which RRT may improve the systemic complications that have led to increased mortality in AKI. In light of recent data demonstrating reduced serum IL-6 and improved outcomes with prophylactic PD in children, we believe that our results are highly clinically relevant.

    Among the dialysis method, Continuous Ambulatory Peritoneal Dialysis (CAPD) is considered as simple, efficient, economical and giving autonomy to the patient. After more than ten year using Continuous Ambulatory Peritoneal Dialysis, results are evaluated. The method remains simple, but the obvious simplicity demands a strict medical control. It is efficient, but the hope in anemia and osteodystrophy correction is not confirmed. It offers more freedom but with a lot of restraints: the dietary restriction must be followed and there is only relative moving autonomia. It is economical, but the costs with the use of disconnectable systems which reduce morbidity, bring it near to the home hemodialysis.

    Peritonitis on catheter of dialysis represents the most frequent complication of the peritoneal dialysis (PD) in the pediatric population. It remains a significant cause of morbidity and mortality. In this study, we investigated the risk factors for peritonitis in children. In this study, we retrospectively collected the records of 85 patients who were treated with PD within the past ten years in the service of pediatrics of the University Hospital Charles-Nicolle of Tunis. Peritonitis rate was 0.75 episode per patient-year. Notably, peritonitis caused by Gram-positive organisms were more common. Analysis of infection risk revealed three significant independent factors: the poor weight (P=0.0045), the non-automated PD (P=0.02) and the short delay from catheter insertion to starting PD (P=0.02). The early onset peritonitis was significantly associated with frequent peritonitis episodes (P=0.0008). The mean duration between the first and second episode of peritonitis was significantly shorter than between PD commencement and the first episode of peritonitis. We revealed a significant association between Gram-negative peritonitis and the presence of ureterostomy (0.018) and between Gram-positive peritonitis and the presence of exit-site and tunnel infections (0.02). Transition to permanent hemodialysis was needed in many children but no death occurred in patients with peritonitis. Considering the important incidence of peritonitis in our patients, it is imperative to establish a targeted primary prevention. Nutritional care must be provided to children to avoid poor weight. The automated dialysis has to be the modality of choice. Copyright © 2015 Association Société de néphrologie. Published by Elsevier SAS. All rights reserved.

  11. Peritoneal dialysis in Asia.

    PubMed

    Cheng, I K

    1996-01-01

    The socioeconomic status of Asian countries is diverse, and government reimbursement policies for treatment of patients suffering from end-stage renal disease (ESRD) vary greatly from one country to another. Both of these factors have a major impact not only on the choice of treatment for ESRD but also on the utilization of peritoneal dialysis (PD) in this region. Based on the data collected from 11 representative Asian countries, several observations can be made. First, the treatment rates for ESRD in these countries correlated closely with their gross domestic product (GDP) per capita income. Second, the PD utilization rate appeared to have a biphasic relationship with the GDP per capita income and treatment rate, in that countries with the highest and the lowest treatment rates tended to have lower PD utilization rates, whereas countries with modest treatment rates tended to have higher PD utilization rates. The reason for low PD utilization in countries with the highest treatment rates differs from that in countries with low treatment rates. In the former, because of full government reimbursement, there is little physician incentive to introduce PD as an alternative form of ESRD treatment to in-center hemodialysis (HD), whereas in the latter, the complete lack of government reimbursement prevents the introduction of PD as a form of treatment. This pattern is likely to change in the future because, of the 11 countries surveyed, all except Thailand have recorded a growth rate which is higher for PD than HD over the last three years. The rate of utilization of different PD systems varies greatly among different Asian countries. Automated PD has yet to gain popularity in Asia. Conventional straight-line systems remain the dominant PD systems in use in Hong Kong, Korea, Thailand, and the Philippines, while in Malaysia and Singapore UV germicidal connection devices are most popular. However, in all these countries there has been a progressive shift over the last

    Certain preventable complications in the treatment of renal failure, in part related to the composition of commercially prepared peritoneal dialysis solutions, continue to occur. Solutions are advocated which would contain sodium 132, calcium 3.5, magnesium 1.5, chloride 102 and lactate or acetate 35 mEq./1., and dextrose 1.5% or about 4.25%. Elimination of 7% dextrose solutions and a reduction of the sodium and lactate concentrations should reduce complications due to hypovolemia, hyperglycemia, hypernatremia and alkalosis. Reduction in the number of solutions should simplify the procedure and perhaps reduce costs. It is anticipated that some of the changes discussed will soon be introduced by industry. PMID:4691094

    Serum folate and vitamin B12 levels have been measured in 32 patients with renal failure. The initial mean serum folate level was raised above normal in seven patients with acute renal failure whereas the mean level in eight patients severely ill from chronic renal failure was significantly lower than normal. Serum folate levels fell during peritoneal dialysis and rose between dialyses in all these patients and also in one patient who was dialysed for acute pancreatitis. The mean serum B12 level was raised in patients with both acute and chronic renal failure, but there was no consistent change in serum B12 level during dialysis. Hypersegmented polymorphs were present in the peripheral blood film of most of the patients with acute or chronic renal failure. Their presence bore no relation to the clinical state, blood urea, serum folate, or serum B12 level of the patients. PMID:5776209

    PubMed

    Opatrná, S

    2008-12-01

    Icodextrin, a glucose polymer, is an alternative osmotic agent to glucose in peritoneal dialysis solutions. Icodextrin generates ultrafiltration through colloid osmosis and is thus effective even during long-term (e.g., nighttime) dwells and in cases of high peritoneal permeability, where it prevents dialysate reabsorption into the systemic circulation. Ultrafiltration is maintained even in the presence of peritonitis. The incidence of bacterial peritonitis is not different when using icodextrin- or glucose-based solutions. Some time ago, icodextrin use was implicated in an increased incidence of sterile peritonitis. This was due to contamination of some batches of the solution by peptidoglycan present in the cell wall of G+ bacteria. Using exact isotope methods, treatment with icodextrin-based solution has been shown to improve the hydration status of peritoneal dialysis patients, suggesting a potential for improved blood pressure control. Icodextrin-based dialysis is associated with a reduction of left ventricular mass. Given the methodological flaws of trials conducted to date, the acute hemodynamic effects of icodextrin cannot be conclusively interpreted. Inclusion of icodextrin-based solution instead of the glucose-based one into the prescription of peritoneal dialysis decreases the metabolic load with glucose potentially having a beneficial effect on hyperlipidemia, hyperinsulinemia and hyperleptinemia, with improved glycemic control in patients with diabetes as an additional benefit. Function of the peritoneum as a dialysis membrane is stable during icodextrin-based treatment, possibly longer compared with glucose-based solutions. Data derived from a large-scale registry have shown lower mortality oficodextrin-treated patients; this, however, needs to be confirmed by prospective randomized controlled trials.

    The long-term results of intermittent peritoneal dialysis in long-term treatment of renal disease have yet to equal those of intermittent hemodialysis. However, further exploration and refinement of this technique is justified. Performed in acute stages of disease, both peritoneal dialysis and hemodialysis relieve the symptoms of uremia and specifically “buy time” for the patient so that proper medical or surgical therapy may be instituted. In acute situations, peritoneal dialysis is the procedure of choice, and is an important adjunct to more conventional treatment for chronic renal disease. It may be useful sometimes even in chronically hemodialyzed patients—for example, when the hemodialysis cannula for one reason or another is inaccessible because of clots, replacement, or infection. It is especially valuable when the hemorrhagic complications of uremia contraindicate hemodialysis treatment. Its use in chronic uremia remains sharply limited in time, but for brief periods chronic peritoneal dialysis appears to be a reasonably satisfactory means of prolonging life while awaiting homotransplant or decision for maintenance hemodialysis therapy.

    Uremic toxicity is related in part to the accumulation of toxic substances, the nature of which has only partly been characterized. Because of the use of a highly permeable membrane and better preservation of the residual renal function, it could be anticipated that some of these uremic toxins are more efficiently cleared across the peritoneal membrane, and that the plasma and tissue levels of these compounds are lower than in hemodialysis patients. This article analyzes the generation and removal of several uremic toxins in peritoneal dialysis patients. The following uremic toxins are discussed: beta2-microglobulin, advanced glycation end products, advanced oxidation protein products, granulocyte inhibitory proteins, p-Cresol, and hyperhomocysteinemia. Some recent studies are reviewed suggesting that uremic toxins are involved in the progression of renal failure and are at least partially removed by peritoneal dialysis. We conclude that, although the plasma levels of some of these compounds are lower in peritoneal dialysis versus hemodialysis patients, it does not mean that the peritoneal dialysis patient is "better" protected against the numerous disturbances caused by these toxins.

    A normocytic normochromic anemia is one of the first signs of renal failure. Since anemia increases morbidity and mortality, its elimination is one of the essential objectives of the treatment. Human recombinant erythropoietin (rHuEPO) has changed the therapeutical approach to anemia. The aim of the present study was to compare efficacy of anemia correction in peritoneal dialysis patients depending on treatment and dialysis modality. The study is the retrospective analysis of 64 patients who presented to our Clinic in 2003. Eighteen (28.13%) patients were treated with rHuEPO, 14 (28%) underwent continuous ambulatory peritoneal dialysis (CAPD), 2 (100%)--automated peritoneal dialysis (APD) and 2 (33.3%)--intermittent peritoneal dialysis (IPD). Mean hemoglobin level was 98.6 +/- 17.82 g/l in patients treated with rHuEPO versus 98.81 +/- 15.14 g/l in patients without rHuEPO treatment. Erythropoietin requirements were 3392.85 +/- 1211.77 IU/week All patients received iron supplementation during rHuEPO therapy. Mean serum ferritin levels were 463.41 +/- 360 ug/l. Transferrin saturation (TSAT) was 0.35 +/- 0.16%. No difference of serum iron and TSAT levels was found between CAPD and IPD patients. The degree of anemia significantly differed between CAPD and IPD patients. A total of 17.11% of PD patients were given blood transfusions, most frequently during the first three months after the onset of dialysis. Our conclusion is that the number of patients receiving rHuEPO should be increased, as 50% of our patients should be substituted, while only 28% are being treated. As 50% of patients receiving rHuEPO failed to reach target Hgb levels, higher EPO doses should be considered. Iron stores should be continuously monitored, particularly in patients receiving rHuEPO, since iron deficiency is an important problem for patients undergoing peritoneal dialysis, especially during erythropoietin therapy. Oral iron supplementation is satisfactory in the majority of patients, and iron

    Peritonitis is a common complication of peritoneal dialysis (PD) and is associated with significant morbidity. Adequate treatment is essential to reduce morbidity and recurrence. To evaluate the benefits and harms of treatments for PD-associated peritonitis. We searched the Cochrane Renal Group's specialised register, the Cochrane Central Register of Controlled Trials (CENTRAL, in The Cochrane Library), MEDLINE, EMBASE and reference lists without language restriction. Date of search: February 2005 All randomised controlled trials (RCTs) and quasi-RCTs assessing the treatment of peritonitis in peritoneal dialysis patients (adults and children) evaluating: administration of an antibiotic(s) by different routes (e.g. oral, intraperitoneal, intravenous); dose of an antibiotic agent(s); different schedules of administration of antimicrobial agents; comparisons of different regimens of antimicrobial agents; any other intervention including fibrinolytic agents, peritoneal lavage and early catheter removal were included. Two authors extracted data on study quality and outcomes. Statistical analyses were performed using the random effects model and the dichotomous results were expressed as relative risk (RR) with 95% confidence intervals (CI) and continuous outcomes as mean difference (WMD) with 95% CI. We identified 36 studies (2089 patients): antimicrobial agents (30); urokinase (4), peritoneal lavage (1) intraperitoneal (IP) immunoglobulin (1). No superior antibiotic agent or combination of agents were identified. Primary response and relapse rates did not differ between IP glycopeptide-based regimens compared to first generation cephalosporin regimens, although glycopeptide regimens were more likely to achieve a complete cure (3 studies, 370 episodes: RR 1.66, 95% CI 1.01 to 3.58). For relapsing or persistent peritonitis, simultaneous catheter removal/replacement was superior to urokinase at reducing treatment failure rates (1 study, 37 patients: RR 2.35, 95% CI 1.13 to

    Objective Peritoneal dialysis remains the only available option for patients which need immediate dialysis and it could be a bridge between end-stage renal failure (ESRD) and transplantation. There is a paucity of published experience of children with immediate use of permanent Tenckhoff Catheter for peritoneal dialysis from developing countries. In this study we report our experience on immediate use of permanent peritoneal access and continued peritoneal dialysis for a prolonged time. Methods Fifty six patients were studied including 30 males and 26 females within the age range of 1 month to 14 years with mean age of 6.5 years in Urmia, Northwest Iran. Findings No operative morbidity was seen. During a total of 499.5 continuous ambulatory peritoneal dialysis months, 16 patients had 28 episodes of peritonitis, which means a overall result of one episode per 17.8 months. There were 3 patients (5.35%) with catheter site leakage, 12 (21.4%) catheter obstructions (which led to omentectomy), 4 (7.2%) exit site infections (2 patients in the early postoperative period and 2 patients in during follow up). Death due to catheter related complications occurred in 1 per 56 patients and due to non-catheter related causes in 10 per 56 patients. Conclusion Present results indicate that catheter-related complications were not higher than those previously reported and peritoneal dialysis could be initiated immediately after catheter implantation and could be a safe bridge between end-stage renal failure (ESRD) and transplantation.

    Artificial liver support gained considerable interest in recent years due to the development of various albumin dialysis systems, which prolong survival of some patients with acute liver failure (ALF). Τhis study aims to examine the role of peritoneal albumin dialysis in a postoperative ALF model. ALF was induced in 14 female Landrace pigs by a combination of major liver resection (70-75% of total parenchyma) and ischemic-reperfusion injury on the liver remnant. Animals were randomly divided in two groups (n = 7 each). Both were monitored for 12 h of reperfusion and received peritoneal dialysis for 6 h, beginning 6 h after reperfusion. The albumin group received an albumin-rich solution and the control group received albumin-free solution. The control group gradually developed intracranial hypertension, whereas, in the albumin group, rise in the intracranial pressure was substantially attenuated (P < 0.01, t = 12 h). Albumin-treated animals had significantly lower levels of ammonia (P < 0.01), total bile acids (P < 0.01), free fatty acids (P < 0.05), lactate (P < 0.01), and total bilirubin (P < 0.05). Liver malondialdehyde and protein carbonyl were significantly reduced (P = 0.007 and P = 0.001 at t = 12 h) after albumin dialysis. Results suggest that this method may become a useful adjunct in the management of ALF, thus, justifying further study. © 2016 Wiley Periodicals, Inc. and International Center for Artificial Organs and Transplantation.

    To determine the feasibility of home tidal peritoneal dialysis (TPD) and to assess whether eight hours of TPD can achieve uremia control and urea removal equal to that of continuous cycling peritoneal dialysis (CCPD). An open enrollment pilot study. The Home Dialysis Training Center of the University of Iowa Hospitals and Clinics, a tertiary care teaching hospital. Nine patients experienced with CCPD and living 80 km to 280 km from the dialysis center began TPD, because they wished to decrease their dialysis time. Following baseline measurements, each patient was taught to perform TPD. TPD consisted of an initial fill volume of 40 mL/kg, a residual volume approximately 20 mL/kg, and tidal exchanges of 10 to 20 mL/kg to achieve the desired hourly flow rate. Clinic assessments took place every four to six weeks, and prescriptions were subsequently altered to attain urea removal equal to that of CCPD. Patient interviews were used to determine TPD acceptance. Prior to each clinic visit, dialysate effluent volume and dialysis duration were recorded, and a sterile sample of the effluent was obtained for urea, creatinine, and total nitrogen measurement. Urea and creatinine clearances increased with dialysate flow. Dialysate nonurea nitrogen was 3.0 +/- 0.2 mmol/kg/D and changed minimally with increasing dialysate volumes. Eight hours of TPD (initial fill: 40 mL/kg; residual volume: 20 mL/kg; tidal inflow: 20 mL/kg) with hourly tidal flow exceeding 40 mL/kg/hr and no daytime volume achieved urea removal equal to that of the patient's prior CCPD prescription. TPD can provide dialysis equal to that of CCPD within a shorter amount of time (eight vs ten hours), but uses a greater volume of dialysate (16.0 L for TPD vs 9.5 L for CCPD).

    The measure of intraperitoneal pressure in peritoneal dialysis is easy and provides clear therapeutic benefits. However it is measured only rarely in adult peritoneal dialysis units. This review aims to disseminate the usefulness of measuring intraperitoneal pressure. This measurement is performed in supine before initiating the drain of a manual exchange with "Y" system, by raising the drain bag and measuring from the mid-axillary line the height of the liquid column that rises from the patient. With typical values of 10-16 cmH2O, intraperitoneal pressure should never exceed 18 cmH2O. With basal values that depend on body mass index, it increases 1-3 cmH2O/L of intraperitoneal volume, and varies with posture and physical activity. Its increase causes discomfort, sleep and breathing disturbances, and has been linked to the occurrence of leaks, hernias, hydrothorax, gastro-esophageal reflux and enteric peritonitis. Less known and valued is its ability to decrease the effectiveness of dialysis significantly counteracting ultrafiltration and decreasing solute clearance to a smaller degree. Because of its easy measurement and potential utility, should be monitored in case of ultrafiltration failure to rule out its eventual contribution in some patients. Although not yet mentioned in the clinical practice guidelines for PD, its clear benefits justify its inclusion among the periodic measurements to consider for prescribing and monitoring peritoneal dialysis.

    Peritonitis is a life-threatening complication of peritoneal dialysis. Peritoneal sclerosis is associated with long-term peritoneal dialysis. The aim of this study was to assess the effect of peritoneal sclerosis on outcomes following laparotomy for peritoneal dialysis peritonitis. A series of 63 consecutive patients underwent laparotomy for peritoneal dialysis peritonitis. Patients were divided into two groups, those with and those without simple peritoneal sclerosis identified at laparotomy. Medical, anaesthetic, and surgical notes were used for data collection. Patients with known encapsulating peritoneal sclerosis were excluded from the study. Patients with simple peritoneal sclerosis had a statistically significant longer duration of peritoneal dialysis. They also had a significantly higher risk of major complications postoperatively and a greater relative risk for mortality. There is an increased prevalence of simple peritoneal sclerosis with long-term peritoneal dialysis. Patients with simple peritoneal sclerosis have higher incidence of postlaparotomy complications. Patients on long-term peritoneal dialysis should be treated aggressively for peritoneal dialysis peritonitis to reduce complication/mortality rates. Evidence of simple peritoneal sclerosis at laparotomy should preclude further peritoneal dialysis.

    Low serum sodium is uncommon in peritoneal dialysis (PD), which is surprising in view of the important role of normal kidney function to regulate water and sodium balance. We report 2 cases of persistent hyponatremia with balance studies in Case 1. We performed measurements of dialysate sodium and volume output over 24 hours in a group of chronic PD patients. The low serum sodium concentration did not vary too much with overall fluid removal via dialysis in patient 1, mainly because large quantities of sodium were removed in the dialysate. In the 24-hour studies, a significant relationship was found between net daily PD sodium removal and net daily dialysate volume removed (r = 0.65). There was no relationship between net daily PD sodium removal and serum sodium concentration. There was a linear direct correlation between serum and dialysate sodium concentration (r = 0.8) as shown by others previously. These results suggest that the main determinant of PD sodium loss is net dialysate ultrafiltration volume. Water loss via dialysis is necessarily associated with sodium loss. In order to maintain a normal serum sodium concentration salt intake must be proportional to the water loss induced by dialysis. The stimuli that allow dialysis patients to maintain this delicate balance between water and salt intake are of considerable interest but remain undetermined.

    A case of Tsukamurella peritonitis associated with peritoneal dialysis in a 23-year-old woman is described. The organism was difficult to identify and was mistaken for Corynebacterium and atypical mycobacteria. Despite prolonged, multidrug, antimicrobial therapy with conventional antibiotics including vancomycin, ciprofloxacin, rifampin, gentamicin and ceftazidime, catheter removal was required to successfully treat peritonitis. Human infection due to this organism is rare and has been previously reported in only 13 cases, 1 of which was peritonitis. We describe here the second case of Tsukamurella peritonitis associated with peritoneal dialysis.

    Optimization of the peritoneal dialysis (PD) prescription includes attempts to normalize the patient's blood pressure and extracellular volume. To do so, one must utilize crystalloid or colloid osmotic agents to achieve ultrafiltration. These osmotic agents are systemically absorbed and thus have both potential benefits and adverse effects. With glucose-based dialysate solutions, the average patient absorbs 300-450 kcal of glucose per day on either continuous ambulatory peritoneal dialysis (CAPD) or the cycler. The amount of glucose absorbed varies based on peritoneal transport characteristics, prescription, and tonicity of fluids used. Alternative osmotic agents such as amino acids and macromolecular solutions, including polypeptides and polyglucose (icodextrin) solutions, have a different rate of systemic absorption and thus a different caloric load profile. In addition, there are protein losses that average about 10 g/day with glucose-based solutions and glucose losses with either amino acid or icodextrin dialysate solutions. There are also potential advantages of these alternative solutions with regard to ultrafiltration. Glucose-based solutions require the development of significant crystalloid osmotic forces, which are dissipated as glucose is absorbed systemically. In contrast, macromolecular solutions achieve ultrafiltration via differences in colloid osmotic pressure, and the absorption of these agents is of a lesser magnitude than glucose-based solutions. Further research is needed to determine other potential risks and benefits of these alternative dialysate solutions.

    Peritoneal dialysis was first employed in patients with acute renal failure in the 1940s and since the 1960s for those with end-stage renal disease. Its popularity increased enormously after the introduction of continuous ambulatory peritoneal dialysis in the end of 1970s. This stimulated both clinical and basic research. In an ideal situation, this should lead to cross-fertilization between the two. The present review describes two examples of interactions: one where it worked out very well and another where basic science missed the link with clinical findings. Those on fluid transport are examples of how old physiological findings on absorption of saline and glucose solutions were adopted in peritoneal dialysis by the use of glucose as an osmotic agent. The mechanism behind this in patients was first solved mathematically by the assumption of ultrasmall intracellular pores allowing water transport only. At the same time, basic science discovered the water channel aquaporin-1 (AQP-1), and a few years later, studies in transgenic mice confirmed that AQP-1 was the ultrasmall pore. In clinical medicine, this led to its assessment in patients and the notion of its impairment. Drugs for treatment have been developed. Research on biocompatibility is not a success story. Basic science has focussed on dialysis solutions with a low pH and lactate, and effects of glucose degradation products, although the first is irrelevant in patients and effects of continuous exposure to high glucose concentrations were largely neglected. Industry believed the bench more than the bedside, resulting in ‘biocompatible’ dialysis solutions. These solutions have some beneficial effects, but are evidently not the final answer.

    The incidence of end-stage renal disease in children is increasing. Peritoneal dialysis (PD) is the modality of choice in many European countries and is increasingly applied worldwide. PD enables children of all ages to be successfully treated while awaiting the ultimate goal of renal transplantation. The advantages of PD over other forms of renal replacement therapy are numerous, in particular the potential for the child to lead a relatively normal life. Indications for commencing PD, the rationale, preparation of family, technical aspects, and management of complications are discussed. PMID:26504404

    Background Peritoneal dialysis (PD) for the treatment of end-stage renal failure was introduced in the 1960s. Nowadays it has evolved to an established therapy that is complementary to hemodialysis (HD), representing 11% of all patients treated worldwide with dialysis. Despite good clinical outcomes and similar results in patient survival between PD and HD, the penetration of PD is decreasing in the Western world. Summary First the major events in the history of the development of PD are described. Then important insights into the physiology of peritoneal transport are discussed and linked to the changes in time observed in biopsies of the peritoneal membrane. Furthermore, the developments in peritoneal access, more biocompatible dialysate solutions, automated PD at home, the establishment of parameters for dialysis adequacy and strategies to prevent infectious complications are mentioned. Finally non-medical issues responsible for the declining penetration in the Western world are analyzed. Key Messages Only after introduction of the concept of continuous ambulatory PD by Moncrief and Popovich has this treatment evolved in time to a renal replacement therapy. Of all structures present in the peritoneal membrane, the capillary endothelium offers the rate-limiting hindrance for solute and water transport for the diffusive and convective transport of solutes and osmosis. The functional and anatomical changes in the peritoneal membrane in time can be monitored by the peritoneal equilibrium test. Peritonitis incidence decreased by introduction of the Y-set and prophylaxis using mupirocin on the exit site. The decrease in the proportion of patients treated with PD in the Western world can be explained by non-medical issues such as inadequate predialysis patient education, physician experience and training, ease of HD initiation, overcapacity of in-center HD, lack of adequate infrastructure for PD treatment, costs and reimbursement issues of the treatment.

    Protein energy wasting is a major complication in peritoneal dialysis. It is leading to a poor quality of life and increasing mortality. Diagnosis must be early, according to criteria defined by the International society of renal nutrition and metabolism. It is necessary to appropriate the diagnostic tools with dialysis method. The nutritional care is difficult in peritoneal dialysis. Indeed, studies are limited and practical nutrition is complex. In this point of view, we propose to treat guidelines for protein energy wasting, in peritoneal dialysis patients. Copyright © 2016 Association Société de néphrologie. Published by Elsevier SAS.

    Standard microbiological tests (i.e., MIC) do not account for the unique factors of peritoneal dialysis (PD)-related peritonitis which can significantly influence treatment response. Our goals were to develop a peritoneal fluid titer (PFT) test and to conduct a pilot study of its association with clinical outcome. The methodology was developed by using spent dialysate collected from patients with bacterial PD-related peritonitis prior to the initiation of antibiotics. Dialysate was processed and spiked with antibiotic to simulate two standard intraperitoneal regimens: cefazolin plus tobramycin and cefazolin alone. Thirty-six clinical isolates, including Staphylococcus epidermidis, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae, and Pseudomonas aeruginosa, were tested. In the pilot study, dialysate was collected from 14 patients with bacterial PD-related peritonitis. Titers were determined by using each patient's dialysate and infecting pathogen. Titers were highly reproducible, with discrepancies in only 1% of cases. Overall, PFTs were notably higher against gram-positive bacteria (P < 0.0001). The addition of tobramycin increased titers significantly from zero to values of 1/16 to 1/64 against E. cloacae and P. aeruginosa (P < 0.0001). In the pilot study, peritoneal fluid inhibitory titers were significantly associated with clinical outcome, with a median value of 1/96 for patients who were cured compared to 1/32 for those who failed treatment (P = 0.036). In conclusion, this study provides preliminary support for the PFT as a pharmacodynamic index specific to the treatment of PD-related peritonitis. With further characterization and validation in patients, the PFT test may advance the study of antibiotic therapies for PD-related peritonitis. PMID:15105126

    Icodextrin-based peritoneal dialysis fluids (PDFs) display several features that may potentially improve their biocompatibility compared to conventional glucose-containing solutions. So far, however, the studies assessing the biocompatibility profile of icodextrin toward human peritoneal mesothelial cells (HPMC) has produced mixed results. The present study was performed to examine the acute and chronic impact of icodextrin on HPMC in vitro in comparison with standard glucose-based PDF. Omentum-derived HPMC were either acutely pre-exposed to or incubated chronically (for up to 10 days) in the presence of icodextrin-PDF. Parallel cultures were treated with conventional PDFs containing either 1.5% or 4.25% glucose. All fluids were tested at neutral pH. HPMC were assessed for viability, proliferation, IL-6 secretion and generation of reactive oxygen species (ROS). Incubation in the presence of icodextrin-PDF significantly reduced HPMC proliferation in a manner similar to that of 1.5% glucose-PDF. In addition, exposure to icodextrin-PDF impaired viability and IL-6 release from HPMC. This effect occurred both after the short pre-treatment with neat icodextrin-PDF for 1-4 hours and after prolonged incubation (up to 10 days) in media supplemented with icodextrin-PDF (1:1). The dysfunction of icodextrin-treated HPMC was of the magnitude that was between the effects exerted by 1.5%- and 4.25%-glucose PDF. Furthermore, exposure of HPMC to icodextrin-PDF induced a dose-dependent increase in ROS generation which was comparable to that produced by 1.5%-glucose PDF. Exposure to icodextrin-PDF may impair viability and function of HPMC. The detrimental effects of icodextrin-PDF are at least as serious as those produced by conventional heat-sterilized low glucose-based PDF.

    In December 2015, as part of the First African Dialysis Conference organized in Dakar, Senegal, 5 physicians from West African countries who have participated in the Saving Young Lives Program reviewed their experiences establishing peritoneal dialysis (PD) programs to treat patients with acute kidney injury (AKI). Thus far, nearly 200 patients have received PD treatment in these countries. The interaction and discussion amongst the participants at the meeting was meaningful and informative. The presentations highlighted the creativity, conviction, and determination of the physicians in overcoming the various barriers and challenges they encountered to establish PD/AKI programs. Hopefully, these successes and the increased awareness of the importance of early diagnosis and treatment of AKI will inspire much needed support from government, hospital, and international organizations.

    Ultrafiltration failure (UFF) is a common complication of peritoneal dialysis (PD). It may be due to a technical problem (PD catheter obstruction or migration, peritoneal leaks or intraperitoneal adhesions) or because of a peritoneal membrane alteration (hyperpermeability, aquaporin dysfunction, peritoneal sclerosis or enhanced lymphatic reabsorption). We, here, present the case of a patient who developed several consecutive PD complications that eventually led to UFF. We also present an algorithm, which may help clinicians to establish a precise etiological diagnosis of UFF.

    Internationally, increasing numbers of patients are requiring treatment for end-stage kidney disease and greater use of peritoneal dialysis is thus being promoted. However, peritonitis can be a significant problem in this population. It is the leading cause of technique failure in patients using peritoneal dialysis and results in considerable morbidity and mortality. There is a dearth of research exploring patients' and their families' experiences of peritonitis. The aim of this paper is to explore patients' and their families' perspectives and experiences of peritonitis. An ethnographic study was conducted in 2011 in the United Kingdom. Sixteen patients and nine of their relatives were recruited through purposive and convenience sampling. In-depth interviews were undertaken with patients and their families, who were also observed using peritoneal dialysis in their homes. The data were analysed thematically using Wolcott's (1994) three-stage approach. This article describes four themes: learning about the risk of peritonitis; measures taken to prevent the infection; how participants monitored continuously for signs and symptoms of the infection; how they then identified and intervened once peritonitis was suspected. Overall, peritonitis was associated with fear and uncertainty, pain and learning from episodes of the infection. Overall, peritonitis was a distressing experience that participants sought to prevent. However, there was some confusion amongst participants about the signs and symptoms of the infection and further education for patients and their families is thus crucial. © 2015 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Peritonitis is the main complication of peritoneal dialysis (PD) and also an important factor for raising the cost of the method to the level of hemodialysis. Associated with PD, peritonitis is responsible for the increase of morbidity and mortality of the procedure and, at the same time, the main cause of the technique failure. Severe and prolonged peritonitis or repeated episodes of peritonitis lead to ultrafiltration failure. Peritonitis treatment should aim for a rapid remission of inflammation in order to preserve the peritoneal membrane functional integrity. The treatment of PD peritonitis consists mainly of antibiotic therapy, surgical intervention not being usually required. However, it is of outmost importance to differentiate the so-called "catheter related" peritonitis from secondary peritonitis due to visceral lesions, in which the surgical treatment comes first. The confusion between secondary and "catheter related" peritonitis may lead to serious errors in choosing the correct treatment, endangering the patient's life. The differential diagnosis between a refractory or secondary peritonitis in a peritoneal dialyzed patient may be very difficult. In front of a refractory PD peritonitis, surgical exploration must not be delayed. Also we have to keep in mind that the aim of peritonitis treatment is the saving of the peritoneal membrane and not the catheter.

She developed acute arthritis, with calcium oxalate crystals in Heberden's and Bouchard's nodes, a phenomenon previously described in gout. Intermittent peritoneal dialysis may be less efficient than hemodialysis in clearing oxalate, and physicians should now consider calcium oxalate-associated arthritis in patients undergoing peritoneal dialysis who are not receiving large doses of ascorbic acid.

    Irisin is a recently discovered myokine thought to be involved in multiple metabolism abnormalities in most dialysis patients. However, the myokine has not been thoroughly studied in peritoneal dialysis. This study aimed to evaluate serum irisin levels and establish their relation to dialysis adequacy, insulin resistance, and bone metabolism status in patients on peritoneal dialysis. A total of 59 nondiabetic prevalent peritoneal dialysis patients and 52 age- and sex-matched healthy controls were enrolled in this cross-sectional study. Serum irisin concentration was assessed by enzyme-linked immunosorbent assay. The correlations between serum irisin and dialysis adequacy, clinical, and metabolic variables were investigated. Serum irisin levels were lower in nondiabetic peritoneal dialysis patients (17.02ng/ml) compared with healthy controls (22.17ng/ml, P<0.001). Multivariate regression analysis revealed that fasting glucose levels were correlated inversely with serum irisin levels in peritoneal dialysis patients. Serum irisin levels were associated with neither insulin resistance nor bone metabolism in our patients. Serum irisin levels were positively associated with peritoneal Kt/Vurea (β = 4.933, 95% confidence interval [CI] = 0.536-9.331, P = 0.029) and peritoneal CCr (β = 0.259, 95% CI = 0.053-0.465, P = 0.015) among peritoneal dialysis patients. The study demonstrated that non-diabetic peritoneal dialysis patients have lower serum irisin levels, and the levels were correlated with peritoneal dialysis adequacy, indicating adequate dialysis may improve irisin secretion. Additional studies are needed to provide a confirmation.

    Background and objectives There is conflicting evidence comparing peritonitis rates among patients treated with continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysis (APD). This study aims to clarify the relationship between peritoneal dialysis (PD) modality (APD versus CAPD) and the risk of developing PD-associated peritonitis. Design, setting, participants, & measurements This study examined the association between PD modality (APD versus CAPD) and the risks, microbiology, and clinical outcomes of PD-associated peritonitis in 6959 incident Australian PD patients between October 1, 2003, and December 31, 2011, using data from the Australia and New Zealand Dialysis and Transplant Registry. Median follow-up time was 1.9 years. Results Patients receiving APD were younger (60 versus 64 years) and had fewer comorbidities. There was no association between PD modality and time to first peritonitis episode (adjusted hazard ratio [HR] for APD versus CAPD, 0.98; 95% confidence interval [95% CI], 0.91 to 1.07; P=0.71). However, there was a lower hazard of developing Gram-positive peritonitis with APD than CAPD, which reached borderline significance (HR, 0.90; 95% CI, 0.80 to 1.00; P=0.05). No statistically significant difference was found in the risk of hospitalizations (odds ratio, 1.12; 95% CI, 0.93 to 1.35; P=0.22), but there was a nonsignificant higher likelihood of 30-day mortality (odds ratio, 1.33; 95% CI, 0.93 to 1.88; P=0.11) at the time of the first episode of peritonitis for patients receiving APD. For all peritonitis episodes (including subsequent episodes of peritonitis), APD was associated with lower rates of culture-negative peritonitis (incidence rate ratio [IRR], 0.81; 95% CI, 0.69 to 0.94; P=0.002) and higher rates of gram-negative peritonitis (IRR, 1.28; 95% CI, 1.13 to 1.46; P=0.01).

    Ischemic stroke is a devastating condition, for which there is still no effective therapy. Acute ischemic stroke is associated with high concentrations of glutamate in the blood and interstitial brain fluid. The inability of the tissue to retain glutamate within the cells of the brain ultimately provokes neuronal death. Increased concentrations of interstitial glutamate exert further excitotoxic effects on healthy tissue surrounding the infarct zone. We developed a strategy based on peritoneal dialysis to reduce blood glutamate levels, thereby accelerating brain-to-blood glutamate clearance. In a rat model of stroke, this simple procedure reduced the transient increase in glutamate, consequently decreasing the size of the infarct area. Functional magnetic resonance imaging demonstrated that the rescued brain tissue remained functional. Moreover, in patients with kidney failure, peritoneal dialysis significantly decreased glutamate concentrations. Our results suggest that peritoneal dialysis may represent a simple and effective intervention for human stroke patients. PMID:23999426

    Exit-site infection (ESI), tunnel infection and associated peritonitis are major causes of morbidity and catheter loss in chronic peritoneal dialysis patients. Meticulous exit-site care is vital in preventing ESI. Avoiding trauma to the exit-site and daily cleaning of the exit-site with a dedicated antimicrobial soap is essential for the longevity of the peritoneal dialysis catheter. Antibiotics cream and disinfectant agents including povidone-iodine, chlorhexidine, electrolytic chloroxidizing solutions (Amuchina 10% - ExSept Plus, Amuchina 5% - ExSept) are useful to keep the resident micro-organisms inhibited. ESI rates in peritoneal dialysis patients treated with Amuchina 10% (ExSept Plus) and Amuchina 5% (ExSept) for the exit-site care are similar or lower compared to povidone-iodine or chlorhexidine. Electrolytic chloroxidizing (Amuchina 10% - ExSept Plus and Amuchina 5% - ExSept) solutions for exit-site care are effective for prevention and treatment of ESI.

Data on patient characteristics including demographics, comorbidities, blood parameters, dialysis adequacy, presence of helpers, medications, and the number PD-related infections were collected. ♦ The age of studied patients was 59±15.0 years, and 47% were female. The prevalence of CI was 28.9%. Patients older than 65 years old (odds ratio [OR] 4.88, confidence interval [CI] 1.79 - 13.28 p = 0.002) and with an education of primary level or below (OR 4.08, CI 1.30 - 12.81, p = 0.016) were independent risk factors for CI in multivariate analysis. Patients with PD-related peritonitis were significantly older (p < 0.001) and more likely to have CI as defined by MoCA (p = 0.035). After adjustment for age, however, CI was not a significant independent risk factor for PD-related peritonitis among self-care PD patients (OR 2.20, CI 0.65 - 7.44, p = 0.20). When we compared patients with MoCA-defined CI receiving self-care and assisted PD, there were no statistically significant differences between the 2 groups in terms of age, MoCA scores, or comorbidities. There were also no statistically significant differences in 1-year outcome of PD-related peritonitis rates or exit-site infections. ♦ Cognitive impairment is common among local PD patients. Even with CI, peritonitis rate in self-care PD with adequate training is similar to CI patients on assisted PD. Copyright © 2016 International Society for Peritoneal Dialysis.

    Chronic peritoneal dialysis (CPD) has been initiated as a treatment modality for chronic renal failure patients in the Indian subcontinent since 1990. Over a period of 9 years both continuous ambulatory peritoneal dialysis (CAPD) and continuous cyclic peritoneal dialysis (CCPD) have emerged as accepted forms of renal replacement therapy in our country. Although there were government restrictions on import of dialysis fluid until 1993, the availability of locally manufactured fluid in collapsible bags had facilitated the expansion of the programme to the far corners of the country and in neighbouring countries. Initially majority (78%) of the patients who were started on this programme were diabetics with other comorbid conditions who were drop-outs from haemodialysis and unfit for transplantation. Both CAPD and CCPD have been used for all age groups and for men and women. Majority of the patients do 3 x 2 l exchanges a day on CAPD; 8-10 l using a cycler at night those who are onCCPD. Peritonitis rate was 1 episode every 18 patient months. With the introduction of new connection and disposable sets the incidence of peritonitis is dropping down. The major cause of drop-out is cardiovascular death followed by peritonitis. Malnutrition is a major problem in both CAPD and haemodialysis patients. The programme has been expanded and there are over one thousand patients on this treatment in the country. The introduction of CPD had a major impact on the treatment of renal failure in India.

    Bacterial peritonitis remains the main cause of technique failure in peritoneal dialysis (PD). During peritonitis, the peritoneal membrane undergoes structural and functional alterations that are mediated by IL-1β The NLRP3 inflammasome is a caspase-1-activating multiprotein complex that links sensing of microbial and stress products to activation of proinflammatory cytokines, including IL-1β The potential roles of the NLRP3 inflammasome and IL-1β in the peritoneal membrane during acute peritonitis have not been investigated. Here, we show that the NLRP3 inflammasome is activated during acute bacterial peritonitis in patients on PD, and this activation associates with the release of IL-1β in the dialysate. In mice, lipopolysaccharide- or Escherichia coli-induced peritonitis led to IL-1β release in the peritoneal membrane. The genetic deletion of Nalp3, which encodes NLRP3, abrogated defects in solute transport during acute peritonitis and restored ultrafiltration. In human umbilical vein endothelial cells, IL-1β treatment directly enhanced endothelial cell proliferation and increased microvascular permeability. These in vitro effects require endothelial IL-1 receptors, shown by immunofluorescence to be expressed in peritoneal capillaries in mice. Furthermore, administration of the IL-1β receptor antagonist, anakinra, efficiently decreased nitric oxide production and vascular proliferation and restored peritoneal function in mouse models of peritonitis, even in mice treated with standard-of-care antibiotherapy. These data demonstrate that NLRP3 activation and IL-1β release have a critical role in solute transport defects and tissue remodeling during PD-related peritonitis. Blockade of the NLRP3/IL-1β axis offers a novel method for rescuing morphologic alterations and transport defects during acute peritonitis. Copyright © 2017 by the American Society of Nephrology.

    We present a 13-year-old girl with Arnold-Chiari syndrome and uremia secondary to neurogenic bladder. She had been treated with continuous ambulatory peritoneal dialysis (CAPD) for 13 months prior to the development of peritonitis. The patient demonstrated no improvement with a 3-day therapy of intraperitoneal vancomycin and netilmicin. Meanwhile, smear of centrifuged dialysate revealed acid fast bacilli on two occasions. We, then, started anti-TB therapy with oral isoniazid (INAH), rifampin and ethambutal. The symptoms subsided within three days. In the first week, the patient lost her peritoneal ultrafiltration and needed daytime automatic peritoneal dialysis. At the last follow-up examination, 12 months after treatment, she remained well on standard CAPD.

    ♦ Background: Peritoneal dialysis (PD)–associated peritonitis clusters within patients. Patient factors contribute to peritonitis risk, but there is also entrapment of organisms within the biofilm that forms on PD catheters. It is hypothesized that this biofilm may prevent complete eradication of organisms, predisposing to multiple infections with the same organism. ♦ Methods: Using data collected in the Canadian multicenter Baxter POET (Peritonitis, Organism, Exit sites, Tunnel infections) database from 1996 to 2005, we studied incident PD patients with 2 or more peritonitis episodes. We determined the proportion of patients with 2 or more episodes caused by the same organism. In addition, using a multivariate logistic regression model, we tested whether prior peritonitis with a given organism predicted the occurrence of a subsequent episode with the same organism. ♦ Results: During their time on PD, 558 patients experienced 2 or more peritonitis episodes. Of those 558 patients, 181 (32%) had at least 2 episodes with the same organism. The organism most commonly causing repeat infection was coagulase-negative Staphylococcus (CNS), accounting for 65.7% of cases. Compared with peritonitis caused by other organisms, a first CNS peritonitis episode was associated with an increased risk of subsequent CNS peritonitis within 1 year (odds ratio: 2.1; 95% confidence interval: 1.5 to 2.8; p < 0.001). Among patients with repeat CNS peritonitis, 48% of repeat episodes occurred within 6 months of the earlier episode. ♦ Conclusions: In contrast to previous data, we did not find a high proportion of patients with multiple peritonitis episodes caused by the same organism. Coagulase-negative Staphylococcus was the organism most likely to cause peritonitis more than once in a given patient, and a prior CNS peritonitis was associated with an increased risk of CNS peritonitis within the subsequent year.

    Continuous flow peritoneal dialysis (CFPD) can be considered a special form of hemodialysis, during which peritoneal effluent, rather than blood, is being dialyzed using standard hemodialysis technology. Preliminary clinical data have identified poor mixing of the dialysis solution, streaming and recirculation as a significant limitation in achieving maximal solute removal and ultrafiltration. Better catheter designs remain a research priority in this field. Although the clinical experience is limited to short-lasting experiments with CFPD, the preliminary data strongly support the superiority of CFPD as the most effective peritoneal dialysis modality in removing small solutes and providing high ultrafiltration rates. The levels of clearance attained are similar to quotidian hemodialysis. In addition, it is expected that the current methodology will provide a new standard of solution biocompatibility.

    Peritoneal dialysis is a form of kidney dialysis that is used to remove accumulated metabolic waste products and water in patients with end stage kidney disease. Long-term exposure to high concentrations of glucose and its by-products, both found in peritoneal dialysis fluid, has been implicated in contributing to peritoneal damage over time, in turn limiting long-term use of the technique. Newer peritoneal dialysis solutions have been developed in the hope of reducing the unfavorable effects of peritoneal dialysis solutions. In vitro and in vivo studies have suggested that newer peritoneal dialysis fluids have salutary effects on the peritoneal membrane. Short-term clinical studies have also found some metabolic benefits of glucose-sparing regimens in chronic peritoneal dialysis. Mixed results have been found in studies examining whether newer peritoneal dialysis fluids reduce peritonitis rates. Long-term studies are needed to investigate whether newer peritoneal dialysis fluids provide better peritoneal dialysis technique and/or patient survival, compared to standard glucose-based peritoneal dialysis fluids.

    Peritonitis is a frequent and serious complication of peritoneal dialysis (PD). Whether low immunoglobulin level is associated with PD-related peritonitis is unknown. We conducted a prospective study to assess whether immunoglobulin levels at PD onset could predict the occurrence of peritonitis. All patients starting peritoneal dialysis between 01/2005 and 12/2010 at the University hospital of Besançon, France, were included in the study. Of 240 consecutive PD patients enrolled (mean follow-up 25 ± 12 months), 76 (32%) had at least one episode of peritonitis. Mean immunoglobulin (Ig)G level at PD start was lower in patients who subsequently experienced peritonitis (7.9 + 3.4 vs. 9.7 + 3.4 g/l, p = 0.005). An increased IgG level at PD onset was associated with a reduced risk of peritonitis [hazard ratio (HR) 0.88, 95% confidence interval (CI) 0.80-0.97 for each increase of 1 g/l in IgG, p = 0.008]. IgG level ≤6.4 g/l ("low IgG") was the best predictive value for the occurrence of subsequent peritonitis: 52 patients (24%) had low IgG levels. At multivariate analysis, both low IgG level (HR 2.49, 95% CI 1.32-4.69, p = 0.005) and diabetes (HR 2.78, 95% CI 1.49-5.20, p = 0.001) were predictive of the occurrence of peritonitis. Low IgG levels predict the occurrence of PD-related peritonitis. Randomized studies should determine whether such patients could benefit from intravenous immunoglobulin administration.

    Since 2009, the peritoneal dialysis (PD) registry survey has been carried out as part of the annual nationwide survey conducted by the Statistical Survey Committee of the Japanese Society for Dialysis Therapy with the cooperation of the Japanese Society for Peritoneal Dialysis. In this report, the current status of PD patients is presented on the basis of the results of the survey conducted at the end of 2012. The subjects were PD patients who lived in Japan and participated in the 2012 survey. Descriptive analysis of various items was performed, which included the current status of the combined use of PD and another dialysis method such as hemodialysis (HD) or hemodiafiltration (HDF), the method of exchanging dialysate, the use of an automated peritoneal dialysis (APD) machine, and the rates of peritonitis and catheter exit-site infection. From the results of the facility survey in 2012, the number of PD patients was 9514, a decrease of 128 from 2011. Among the entire dialysis patient population, 3.1% were PD patients, a decrease of 0.1%. Among the studied patients, 347 had a peritoneal catheter and underwent peritoneal lavage, 175 were started on PD in 2012 but introduced to other blood purification methods in the same year, and 1932 underwent both PD and another dialysis method such as HD or HDF. The percentage of patients who underwent PD and another dialysis method increased with PD vintage: <1 year, 4.8%; 1 to <2 years, 9.2%; 2 to <4 years, 16.3%; 4 to <8 years, 32.0%; and ≥8 years, 47.5%. The percentage of PD patients who completely manually exchanged the dialysate was 29.8%. The percentages of PD patients who used a double-bag exchange system with ultraviolet-light irradiation and those who used the same system but with a sterile connecting device were 54.7 and 13.9%, respectively. The percentage of patients on PD for <1 year using an APD machine was 43.4%, and it decreased with a PD vintage of ≥2 years. The mean rate of peritonitis was 0.22 per patient

  20. Aquaporin-1 in the peritoneal membrane: Implications for water transport across capillaries and peritoneal dialysis.

    PubMed

    2006-08-01

    Peritoneal dialysis (PD) is an established mode of renal replacement therapy, based on the exchange of fluid and solutes between blood in peritoneal capillaries and a dialysate that has been introduced in the peritoneal cavity. The dialysis involves diffusive and convective transports and osmosis through the highly vascularized peritoneal membrane. Computer simulations predicted that the membrane contains ultrasmall pores (radius < 3 A) responsible for the transport of solute-free water across the capillary endothelium during crystalloid osmosis. The distribution of the water channel aquaporin-1 (AQP1), as well as its molecular structure ensuring an exquisite selectivity for water perfectly fit with the characteristics of the ultrasmall pore. Treatment with corticosteroids induces the expression of AQP1 in peritoneal capillaries and increases water permeability and ultrafiltration in rats, without affecting the osmotic gradient and the permeability for small solutes. Studies in knockout mice provided further evidence that osmotically-driven water transport across the peritoneal membrane is mediated by AQP1. AQP1 and endothelial NO synthase (eNOS) show a distinct regulation within the endothelium lining peritoneal capillaries. In acute peritonitis, the upregulation of eNOS and increased release of NO dissipate the osmotic gradient and result in ultrafiltration failure, despite the unchanged expression of AQP1. These data illustrate the potential of the peritoneal membrane to investigate the role and regulation of AQP1 in the endothelium. They also emphasize the critical role of AQP1 during peritoneal dialysis and suggest that manipulating AQP1 expression may be used to increase water permeability across the peritoneal membrane.

Renal dialysis center. Ten episodes of peritonitis occurred in 8 of 61 patients over a 6-month period in which 669 IPD procedures were analyzed. Field visit to renal dialysis center to examine the entire IPD procedure, inspect the hospital environment, and perform air bacterial count. The environmental factors and risk factors contributing to the polymicrobial peritonitis outbreak in IPD patients. The incidence of IPD peritonitis was determined before and after interventions. The causative organisms included Acinetobacter baumanii (6), Stenotrophomonas maltophilia (2), Pseudomonas aeruginosa (1), Candida albicans (1), C. tropicalis (1), Enterococcus (3), and Enterobacteriaceae (2). Four episodes of peritonitis involved infection by more than one organism. Air sampling of the environment detected a median of 110 colony forming units of bacteria per cubic meter of air, 10% of which were found to be Acinetobacter baumanii. The source of this polymicrobial outbreak was attributed to the bamboo scaffolding structure covering the external wall of the hospital during renovation. A retrospective case-control study indicated that the absence of the flush-before-fill step was a risk factor for development of peritonitis. In addition to invasive aspergillosis in transplant or oncology patients, Acinetobacter peritonitis in dialysis patients should be considered another microbial cause of outbreak associated with hospital renovation.

    Peritonitis is a leading complication of chronic ambulatory peritoneal dialysis. However, very rarely does Neisseria mucosa cause peritonitis. We describe an unusual case of N. mucosa peritonitis in a chronic ambulatory peritoneal dialysis patient. A 28-year-old Hispanic male presents with diffuse abdominal pain exacerbated during draining of the peritoneal fluid. Peritoneal fluid examination was remarkable for leukocytosis and gramnegative diplococci. Bacterial cultures were positive for N. mucosa growth. The patient was treated with ciprofloxacin with preservation of the dialysis catheter. This case highlights the rarity and importance of Neisseria mucosa causing peritonitis in chronic ambulatory peritoneal dialysis patients’. There seems to be a unique association between N. mucosa peritonitis and chronic ambulatory peritoneal dialysis patients’. The patient was successfully managed with ciprofloxacin along with salvaging of the dialysis catheter. PMID:28191300

    The process of continuous ambulatory peritoneal dialysis has provided a useful, relatively inexpensive, and safe alternative for patients with end-stage renal disease. Infectious peritonitis, however, has limited a more widespread acceptance of this technique. The definition of peritonitis in this patient population is not universally accepted and does not always include the laboratory support of a positive culture (or Gram stain). In part, the omission of clinical microbiological findings stems from the lack of sensitivity of earlier microbiological efforts. Peritonitis results from decreased host phagocytic efficiency with depressed phagocytosis and bactericidal capacity of peritoneal macrophages. During episodes of peritonitis, fluid movement is reversed, away from the lymphatics and peritoneal membrane and toward the cavity. As a result, bloodstream infections are rare. Most peritonitis episodes are caused by bacteria. Coagulase-negative staphylococci are the most frequently isolated organisms, usually originating from the skin flora, but a wide array of microbial species have been documented as agents of peritonitis. Clinical microbiology laboratories need to be cognizant of the diverse agents so that appropriate primary media can be used. The quantity of dialysate fluid that is prepared for culture is critical and should constitute at least 10 ml. The sensitivity of the cultural approach depends on the volume of dialysate, its pretreatment (lysis or centrifugation), the media used, and the mode of incubation. The low concentration of microorganisms in dialysate fluids accounts for negative Gram stain results. Prevention of infection in continuous ambulatory peritoneal dialysis patients is associated with the socioeconomic status of the patient, advances in equipment (catheter) technology, and, probably least important, the application of prophylactic antimicrobial agents.

    After major open heart surgery, a significant number of infants and children are dependent on peritoneal dialysis as a result of renal impairment. They often require broad-spectrum antibiotics for the treatment of ongoing infections or as prophylactic therapy and have an increased risk of fungal infection. Fluconazole is a new thiazole antifungal agent that has been widely used in adults, but its use in children with acute renal impairment requiring peritoneal dialysis has not been documented. The purpose of this investigation was to study the pharmacokinetics of fluconazole in infants and children who developed various degrees of renal impairment, with or without the need for peritoneal dialysis, after major open heart surgery. Between January 1992 and June 1995, 17 children ranging in age from 2 weeks to 3 years (mean, 6 months) who received fluconazole therapy intravenously (3 mg/kg per day for 2 to 3 weeks) after major open heart surgery were enrolled in a prospective study. They were divided into two groups--those who required peritoneal dialysis (PD group; n = 8) and those who did not (non-PD group; n = 9). Blood, urine, and peritoneal dialysate samples were collected for 4 days to determine the pharmacokinetics of the drug, and data were compared between the two groups. The two groups of children had similar demographic characteristics, and their plasma concentrations of fluconazole showed no statistically significant differences. For children dependent on peritoneal dialysis, fluconazole was excreted almost solely through dialysis. Despite a significantly longer terminal elimination half-life for this group of infants, they tended to have a marginally larger volume of distribution of the drug. This, coupled with the continuous hourly exchange of dialysate, provided a large sink volume to effectively remove flu- conazole from the circulation. Thus the plasma clearance and the accumulation ratio were comparable for the two groups of children. Continuous

    To analyze the incidence rates and risk factors for bacteremia in patients undergoing hemodialysis (HD) and peritoneal dialysis (PD). The records of 898 consecutive patients undergoing dialysis from January 2003 to December 2008 were reviewed retrospectively. Episodes of bacteremia were recorded. China Medical University (Taichung, Taiwan). The overall incidence rate of bacteremia was 7.63 per 100 patient-years in HD patients and 3.56 per 100 patient-years in PD patients and it was higher in HD patients each year from 2003 to 2008. S. aureus (27.53%) was the most common pathogen in HD patients, whereas Coagulase-negative Staphylococcus (21.3%) was the most common pathogen in PD patients. Vascular access infection was the most common etiology in HD patients, whereas peritonitis was the most common etiology in PD patients. Older age, shorter dialysis vintage, use of HD rather than PD, current smoker, use of a venous dialysis catheter, presence of diabetes mellitus, higher comorbidity score, and lower serum albumin were significant risk factors for bacteremia. Diabetes mellitus and lower serum albumin were significant risk factors for bacteremia-associated mortality. Placement of a permanent access (fistula, graft, or PD catheter) prior to initiation of dialysis, smoking cessation, and better nutritional status (i.e. higher serum albumin) were associated with a reduced risk of bacteremia in dialysis patients. Higher serum albumin was also associated with a reduced bacteremia-associated mortality.

    Background Bacterial infections account for most peritoneal dialysis (PD)-associated peritonitis episodes. However, anaerobic PD peritonitis is extremely rare and intuitively associated with intra-abdominal lesions. In this study, we examined the clinical characteristics of PD patients who developed anaerobic peritonitis. Methods We retrospectively identified all anaerobic PD peritonitis episodes from a prospectively collected PD registry at a single center between 1990 and 2010. Only patients receiving more than 3 months of PD were enrolled. We analyzed clinical features as well as outcomes of anaerobic PD peritonitis patients. Results Among 6 patients, 10 episodes of PD-associated peritonitis were caused by anaerobic pathogens (1.59% of all peritonitis episodes during study the period), in which the cultures from 5 episodes had mixed growth. Bacteroides fragilis was the most common species identified (4 isolates). Only 3 episodes were associated with gastrointestinal lesions, and 4 episodes were related to a break in sterility during exchange procedures. All anaerobic pathogens were susceptible to clindamycin and metronidazole, but penicillin resistance was noted in 4 isolates. Ampicillin/sulbactam resistance was found in 2 isolates. In 5 episodes, a primary response was achieved using the first-generation cephalosporin and ceftazidime or aminoglycoside. In 3 episodes, the first-generation cephalosporin was replaced with aminoglycosides. Tenckhoff catheter removal was necessary in 2 episodes. Only one episode ended with mortality (due to a perforated bowel). Conclusion Anaerobic PD-associated peritonitis might be predominantly caused by contamination, rather than intra-abdominal events. Half of anaerobic PD-associated peritonitis episodes had polymicrobial growth. The overall outcome of anaerobic peritonitis is fair, with a high catheter survival rate. PMID:23705895

    Encapsulating peritoneal sclerosis (EPS) is a rare but serious complication seen in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) or automated peritoneal dialysisAPD after prolonged duration on dialysis. Patients usally present with vague complaints of abdominal pain, vomitting, diarrhea, weight loss and change in peritoneal transport characte-ristics. High degree of suspicion is needed in PD patients who have been on dialysis for prolonged duration and have been using high-concentrated dialysis fluid. Mycobacterium fortuitum (MF) is a rapidly growing, non-tuberculous mycobacterium that has rarely been reported as a pathogen causing peritonits in patients on PD. We report a case of CAPD presenting with culture-negative peritonits, which, on specific culture, grew MF and, on radiological evaluation, showed diagnostic features of EPS.

    A 48-year-old man receiving maintenance hemodialysis for 3 years and continuous ambulatory peritoneal dialysis for 1 year developed a clinical picture compatible with peritonitis. Three successive fluid cultures were negative, and only after filtration of a large volume of peritoneal fluid a fungus identified as a Rhizopus sp was isolated in cultures of the filtering devices. The same fungus was also isolated from the peritoneal catheter cuff. Intravenous amphotericin B was administered and both the abdominal and general conditions of the patient improved transiently. Twenty days after initiation of antifungal treatment, a clinical suspicion of intestinal perforation arose and an exploratory laparotomy was scheduled, but the patient died during the anesthetic induction. The patient never received deferoxamine; any conditions predisposing to mucormycosis, such as diabetes or immunosuppression, were also absent.

    To review the outcome for Chinese infants and young children on chronic peritoneal dialysis. The Paediatric Nephrology Centre of Princess Margaret Hospital is the designated site offering chronic dialysis to children in Hong Kong. Medical records of children who started chronic peritoneal dialysis before the age of 2 years, from 1 July 1995 to 31 December 2013, were retrieved and retrospectively reviewed. Nine Chinese patients (male-to-female ratio, 3:6) were identified. They were commenced on automated peritoneal dialysis at a median age of 4.7 (interquartile range, 1.1-13.3) months. The median duration of chronic peritoneal dialysis was 40.9 (interquartile range, 22.9-76.2) months. The underlying aetiologies were renal dysplasia (n=3), pneumococcal-associated haemolytic uraemic syndrome (n=3), ischaemic nephropathy (n=2), and primary hyperoxaluria I (n=1). Peritonitis and exit-site infection rate was 1 episode per 46.5 patient-months and 1 episode per 28.6 patient-months, respectively. Dialysis adequacy (Kt/Vurea>1.8) was achieved in 87.5% of patients. Weight gain was achieved in our patients although three required gastrostomy. Four patients were delayed in development. All patients survived except one patient with primary hyperoxaluria I who died of acute portal vein thrombosis following liver transplantation. One patient with pneumococcal-associated haemolytic uraemic syndrome had sufficient renal function to be weaned off dialysis. Four patients received deceased donor renal transplantation after a mean waiting time of 76.7 months. Three patients remained on chronic peritoneal dialysis at the end of the study. Chronic peritoneal dialysis is technically difficult in infants. Nonetheless, low peritonitis rate, low exit-site infection rate, and no chronic peritoneal dialysis-related mortality can be achieved. Chronic peritoneal dialysis offers a promising strategy to bridge the way to renal transplantation.

    During peritoneal dialysis (PD), the peritoneal membrane undergoes ageing processes that affect its function. Here we analyzed associations of patient age and dialysis vintage with parameters of peritoneal transport of fluid and solutes, directly measured and estimated based on the pore model, for individual patients. Thirty-three patients (15 females; age 60 (21-87) years; median time on PD 19 (3-100) months) underwent sequential peritoneal equilibration test. Dialysis vintage and patient age did not correlate. Estimation of parameters of the two-pore model of peritoneal transport was performed. The estimated fluid transport parameters, including hydraulic permeability (LpS), fraction of ultrasmall pores (α u), osmotic conductance for glucose (OCG), and peritoneal absorption, were generally independent of solute transport parameters (diffusive mass transport parameters). Fluid transport parameters correlated whereas transport parameters for small solutes and proteins did not correlate with dialysis vintage and patient age. Although LpS and OCG were lower for older patients and those with long dialysis vintage, αu was higher. Thus, fluid transport parameters--rather than solute transport parameters--are linked to dialysis vintage and patient age and should therefore be included when monitoring processes linked to ageing of the peritoneal membrane.

    Introduction: Non-Pseudomonas gram-negative bacteria are responsible for an increasing proportion of cases of peritoneal dialysis (PD)-related peritonitis. The role of Citrobacter species in the etiology of PD-related peritonitis is often underestimated. In the present study, we aimed to describe the clinical features, laboratory findings, and short- and long-term outcomes in PD-related peritonitis caused by Citrobacter. Methods: A retrospective review of all episodes of PD-related peritonitis caused by Citrobacter from a single center between 1990 and 2010 was performed. Clinical features, microbiological data, and outcomes of these episodes were analyzed. Results: Citrobacter species was responsible for 11 PD-related episodes (1.8% of all peritonitis episodes) in 8 patients. Citrobacter freundii was the most common etiologic species (73%), and mixed growth was found in the other 3 episodes (27%). Approximately half (46%) of the episodes were associated with constipation and/or diarrhea. Of the Citrobacter isolates from all episodes, 54% were resistant to cefazolin, and only 18% were susceptible to cefmetazole. All isolates were susceptible to ceftazidime, cefepime, carbapenem, and aminoglycosides. More than half of the patients (54%) were hospitalized for index peritonitis, and 27% of the episodes involved a change in antibiotic medication. One patient had relapsing peritonitis caused by C. koseri (9%). The mortality rate of PD-related peritonitis caused by Citrobacter was 18%, and 89% of surviving patients developed technique failure requiring a modality switch after an average of 12 months of follow-up (range 1.2-31.2 months). Conclusion: PD-related peritonitis caused by Citrobacter is associated with poor outcomes, including high rates of antibiotic resistance, a high mortality rate, and a high rate of technique failure among survivors during the follow-up period.

  13. Peritoneal Dialysis Complicated by Pleuroperitoneal Communication and Hydrothorax

    PubMed Central

    Yaxley, Julian; Twomey, Kevin

    2017-01-01

    Background: Hydrothorax is an uncommon but well-recognized complication of peritoneal dialysis. It is a potentially serious condition that frequently requires cessation of peritoneal dialysis and permanent transition to hemodialysis. Hydrothorax is produced by movement of peritoneal dialysate through pleuroperitoneal fistulas. Pleural fluid analysis typically detects a high glucose concentration, and contrast imaging reveals tracer uptake transgressing the diaphragm. Experience with the treatment of hydrothorax related to peritoneal dialysis is limited. Case Report: We describe the case of a 54-year-old female on peritoneal dialysis for end-stage renal failure who developed a hydrothorax soon after beginning treatment. Conclusion: This case describes a classical presentation of hydrothorax in the context of peritoneal dialysis. Treatment is frequently unsuccessful. All clinicians prescribing peritoneal dialysis should be aware of this complication. PMID:28331461

    ♦ This study was carried out to examine whether or not elderly patients on peritoneal dialysis (PD) had an increased risk of peritonitis. ♦ This was a retrospective cohort study based on data from the French Language Peritoneal Dialysis Registry. We analyzed 8,396 incident patients starting PD between January 2003 and December 2010. The end of the observation period was 31 December 2012. Patients were separated into 2 age groups: up to 75 and over of 75 years old. ♦ Among 8,396 patients starting dialysis there were 3,173 patients older than 75. When using a Cox model, no association was found between age greater than 75 years and increased risk of peritonitis (hazard ratio [HR]: 0.97 [0.88 - 1.07]). Diabetes (HR: 1.14 [1.01 - 1.28] and continuous ambulatory PD (HR: 1.13 [1.04 - 1.23]) were significantly associated with a higher risk of peritoneal infection whereas nurse-assisted PD was associated with a lower risk of peritonitis (HR: 0.85 [0.78 - 0.94]. In the analysis restricted to the 3,840 self-care PD patients, there was no association between age older than 75 years and risk of peritonitis. ♦ The risk of peritonitis is not increased in elderly patients on PD in a country where assisted PD is available.

    A case of Berardinelli-Seip syndrome, a congenital generalised lipodystrophy, is reported. Symptoms first appeared when the patient was 20 years old. She showed severe insulin resistance as well as micro- and macro-angiopathic complications, including chronic kidney disease, which required renal replacement therapy with peritoneal dialysis. The patient's clinical course was reviewed since paediatric age (when initial signs of the disease being already evident) to present time. Berardinelli-Seip syndrome is very uncommon, and the present case is particularly rare because it is the only case (at least as reported in the literature) in a patient receiving dialysis.

    Little or no evidence is available on the impact of the first peritonitis episode on peritoneal transport characteristics. The objective of this study was to investigate the importance of the very first peritonitis episode and distinguish its effect from the natural course by comparison of peritoneal transport before and after infection. We analyzed prospectively collected data from 541 incident peritoneal dialysis (PD) patients, aged > 18 years, between 1990 and 2010. Standard Peritoneal Permeability Analyses (SPA) within the year before and within the year after (but not within 30 days) the first peritonitis were compared. In a control group without peritonitis, SPAs within the first and second year of PD were compared. SPA data included the mass transfer area coefficient of creatinine, glucose absorption and peritoneal clearances of β-2-microglobulin (b2m), albumin, IgG and α-2-macroglobulin (a2m). From these clearances, the restriction coefficient to macromolecules (RC) was calculated. Also, parameters of fluid transport were determined: transcapillary ultrafiltration rate (TCUFR), lymphatic absorption (ELAR), and free water transport. Crude and adjusted linear mixed models were used to compare the slopes of peritoneal transport parameters in the peritonitis group to the control group. Adjustments were made for age, sex and diabetes. Of 541 patients, 367 experienced a first peritonitis episode within a median time of 12 months after the start of PD. Of these, 92 peritonitis episodes were preceded and followed by a SPA within one year. Forty-five patients without peritonitis were included in the control group. Logistic reasons (peritonitis group: 48% vs control group: 83%) and switch to hemodialysis (peritonitis group: 22% vs control group: 3%) were the main causes of missing SPA data post-peritonitis and post-control. When comparing the slopes of peritoneal transport parameters in the peritonitis group and the control group, a first peritonitis episode was

    Foreign body reaction is a tissue response against implanted materials. We described for the first time the eosinophilic peritonitis and foreign body giant cell reaction to dialysis catheter in a nonatopic child on continuous ambulatory peritoneal dialysis. We found tenderness, redness, and swelling without purulent discharge around the peritoneal catheter; increased eosinophil count in cloudy dialysis fluid; and blood and hyperechoic granulomatous formation appearance surrounding the peritoneal catheter on ultrasonography and foreign body giant cell reaction to dialysis catheter in pathologic examination of granulomatous lesionin in our patient. The peritoneal dialysis catheter was removed due to resistance to antibiotic and antihistamine treatments for suspected peritonitis and tunnel infection. Foreign body reaction and eosinophilic peritonitis with eosinophilic cloudy dialysis effluent can exist simultaneously. Foreign body reaction should be considered in the differential diagnosis of exit site and/or tunnel infection. Ultrasonography helps distinguish between foreign body reaction and exit-site or tunnel infection.

    There has not been a comprehensive examination to date of peritoneal dialysis (PD) outcomes after temporary haemodialysis (HD) transfer for peritonitis. The study included all incident Australian patients who experienced peritonitis between 1 October 2003, and 31 December 2011, using Australia and New Zealand Dialysis and Transplant Registry data. Patients were grouped into three categories: Interim HD, Permanent HD and Never HD based on HD transfer status after the first peritonitis. The independent predictors of HD transfer and subsequent return to PD were determined by multivariable, multilevel mixed-effects logistic regression analysis. Matched case-control analyses were performed to compare clinical outcomes (e.g. patient survival) between groups. Of the 3305 patients who experienced peritonitis during the study period, 553 episodes (16.7%) resulted in transfer to HD and 101 patients subsequently returned to PD. HD transfer was significantly and independently predicted by inpatient treatment of peritonitis [odds ratio (OR) 11.45, 95% confidence interval (CI) 7.14-18.36] and the recovered microbiologic profile of organisms recognized to be associated with moderate (20-40%) to high (>40%) rates of catheter removal (moderate: OR 2.45, 95% CI 1.89-3.17; high: OR 8.63, 95% CI 6.44-11.57). Matched case-control analyses yielded comparable results among Interim, Permanent and Never HD groups in terms of patient survival (P = 0.28), death-censored technique survival [hazard ratio (HR) 0.87, 95% CI 0.59-1.28; P = 0.48] and peritonitis-free survival (HR 0.84, 95% CI 0.50-1.39, P = 0.49). In an observational registry study of first peritonitis episodes, temporary HD transfer was not associated with inferior patient-level clinical outcomes when compared with others who either never required HD transfer or remained on HD permanently if all patient-level and peritonitis-related factors were considered equal. Therefore, return to PD after a temporary HD due to peritonitis

    For a long time bicarbonate, the physiological buffer of the body, was suggested to be the best buffer for peritoneal dialysis. However, since the production of bicarbonate-containing solutions is associated with technical problems, lactate was favored. To avoid the well-known disadvantages of lactate solution concerning biocompatibility and possible metabolic side effects, different attempts have been made to use bicarbonate as a buffer in peritoneal dialysis. One of the major approaches was the total replacement of lactate by bicarbonate combined with storage of the fluid in a specially designed double-chamber bag. Further solutions of the above-mentioned problem were the on-line preparation of bicarbonate fluids for intermittent peritoneal dialysis, the addition of bicarbonate just before use, the combination of bicarbonate with organic acids, or its combination with the dipeptide glycylglycine as a stabilizing agent. By now, the beneficial effect of the neutral bicarbonate fluid, for example, on cell viability and cell functions, has been demonstrated in many different in vitro and animal studies. However, only few reports on clinical experience have been published. These investigations demonstrated independently that bicarbonate fluids diminish inflow pain, are well tolerated by the patients, and may correct metabolic acidosis of uremic patients. A controlled randomized multicenter trial using 34 mmol/L bicarbonate for at least three months confirmed that bicarbonate is as efficacious as lactate in equimolar concentrations. Concomitant investigations on energy metabolism and redox state of red blood cells and phospholipid secretion of mesothelial cells additionally demonstrated the improvement of cell function with bicarbonate solutions. For some patients with severe metabolic acidosis the bicarbonate concentration used in the multicenter trial seemed to be too low. Thus, a fluid containing a higher bicarbonate concentration was tested in a pilot study

    An unusual case of diabetes secondary to acute pancreatitis in a boy with end-stage renal failure receiving continuous ambulatory peritoneal dialysis (CAPD) is described. A hyperglycaemic, hyperosmolar pre-coma developed, aggravated by associated hypercalcaemia. The glucose content of the dialysis fluid contributed to the hyperglycaemia, which settled as the pancreatitis resolved and lower glucose concentration dialysis fluid was used. Our experience suggests that pancreatic dysfunction should be considered where significant hyperglycaemia occurs during peritoneal dialysis.

    Background Acinetobacter species are assuming an increasingly important role in modern medicine, with their persistent presence in health-care settings and antibiotic resistance. However, clinical reports addressing this issue in patients with peritoneal dialysis (PD) peritonitis are rare. Methods All PD peritonitis episodes caused by Acinetobacter that occurred between 1985 and 2012 at a single centre were retrospectively reviewed. Clinical features, microbiological data, and outcomes were analysed, with stratifications based upon temporal periods (before and after 2000). Results Acinetobacter species were responsible for 26 PD peritonitis episodes (3.5% of all episodes) in 25 patients. A. baumannii was the most common pathogen (54%), followed by A. iwoffii (35%), with the former being predominant after 2000. Significantly more episodes resulted from breaks in exchange sterility after 2000, while those from exit site infections decreased (P = 0.01). The interval between the last and current peritonitis episodes lengthened significantly after 2000 (5 vs. 13.6 months; P = 0.05). All the isolates were susceptible to cefepime, fluoroquinolone, and aminoglycosides, with a low ceftazidime resistance rate (16%). Nearly half of the patients (46%) required hospitalisation for their Acinetobacter PD-associated peritonitis, and 27% required an antibiotic switch. The overall outcome was fair, with no mortality and a 12% technique failure rate, without obvious interval differences. Conclusions The temporal change in the microbiology and origin of Acinetobacter PD-associated peritonitis in our cohort suggested an important evolutional trend. Appropriate measures, including technique re-education and sterility maintenance, should be taken to decrease the Acinetobacter peritonitis incidence in PD patients. PMID:25314341

The study provides a systematic review of the literature (MEDLINE search with icodextrin as the keyword). Results. Icodextrin induces sustained transcapillary ultrafiltration during long dwell periods. It also stimulates increased removal of sodium by the peritoneal membrane, reduction of extracellular water (ECW) and total body water (TBW). Effects of icodextrin on blood pressure control and residual renal function are discrepant. Icodextrin induces a reduction in the formation of advanced glycation end-products, while the longitudinal changes in the peritoneal membrane transport are less prominent. Conclusions. Use of icodextrin in PD improves the sodium and fluid balance. Icodextrin is potentially more biocompatible, when compared with the conventional glucose solutions. The side effects are rare.

    Peritoneal dialysis (PD) is a preferred home dialysis modality and has a number of added advantages including improved initial patient survival and cost effectiveness over haemodialysis. Despite these benefits, uptake of PD remains relatively low, especially in developed countries. Wider implementation of PD is compromised by higher technique failure from infections (e.g., PD peritonitis) and ultrafiltration failure. These are inevitable consequences of peritoneal injury, which is thought to result primarily from continuous exposure to PD fluids that are characterised by their “unphysiologic” composition. In order to overcome these barriers, a number of more biocompatible PD fluids, with neutral pH, low glucose degradation product content, and bicarbonate buffer have been manufactured over the past two decades. Several preclinical studies have demonstrated their benefit in terms of improvement in host cell defence, peritoneal membrane integrity, and cytokine profile. This paper aims to review randomised controlled trials assessing the use of biocompatible PD fluids and their effect on clinical outcomes. PMID:23251801

    This review focuses on the strategy of patient selection for peritoneal dialysis (PD) based on published epidemiology studies and observational data. With the success of the PD first model in Hong Kong, experience shows that there is no particular patient group that cannot be put on PD except those who have major problems in the abdomen. Incident patients should be offered the choice to receive PD at the start of dialysis in order to preserve better the residual renal function. Concern has also been expressed for a time-dependent negative impact of PD on survival, although PD in general provides survival advantage at least during the first few years after the start of dialysis. Regular patient review is essential to allow prompt adjustment of the dialysis regimen and modality when required. Accumulating research suggests that center size has a significant effect on the patient and technique survival of patients undergoing PD. Comorbid diabetes, large and small body size, peritoneal membrane transport status, elderly age group, and socioeconomic status are important patient factors to consider. Good clinical and psychosocial care of the PD patients are essential as well as the attention to their compliance. Enhanced training to medical and nursing personnel on PD is one of the key success factors for improving its utilization and outcome.

    The impact of different dialysis modalities on clinical outcomes has not been explored in young infants with chronic kidney failure. Cohort study. Data were extracted from the ESPN/ERA-EDTA Registry. This analysis included 1,063 infants 12 months or younger who initiated dialysis therapy in 1991 to 2013. Type of dialysis modality. Differences between infants treated with peritoneal dialysis (PD) or hemodialysis (HD) in patient survival, technique survival, and access to kidney transplantation were examined using Cox regression analysis while adjusting for age at dialysis therapy initiation, sex, underlying kidney disease, and country of residence. 917 infants initiated dialysis therapy on PD, and 146, on HD. Median age at dialysis therapy initiation was 4.5 (IQR, 0.7-7.9) months, and median body weight was 5.7 (IQR, 3.7-7.5) kg. Although the groups were homogeneous regarding age and sex, infants treated with PD more often had congenital anomalies of the kidney and urinary tract (CAKUT; 48% vs 27%), whereas those on HD therapy more frequently had metabolic disorders (12% vs 4%). Risk factors for death were younger age at dialysis therapy initiation (HR per each 1-month later initiation, 0.95; 95% CI, 0.90-0.97) and non-CAKUT cause of chronic kidney failure (HR, 1.49; 95% CI, 1.08-2.04). Mortality risk and likelihood of transplantation were equal in PD and HD patients, whereas HD patients had a higher risk for changing dialysis treatment (adjusted HR, 1.64; 95% CI, 1.17-2.31). Inability to control for unmeasured confounders not included in the Registry database and missing data (ie, comorbid conditions). Low statistical power because of relatively small number of participants.

    The hydrothorax is a known but rare complication of acute and chronic peritoneal dialysis. Patients with hemolytic uremic syndrome seem to be more prone to this complication. Usually discontinuation of treatment is necessary due to the lack of resolution or recurrence of hydrothorax and transfer to hemodialysis, but some patients can continue dialysis with modification of technique and with resolution of hydrothorax.

    Abstract Introduction: Halomonas hamiltonii is a Gram-negative, halophilic, motile, and nonspore-forming rod bacterium. Although most Halomonas sp. are commonly found in saline environments, it has rarely been implicated as a cause of human infection. Herein, the authors present a case report of continuous ambulatory peritoneal dialysis (CAPD)-related peritonitis attributed to H hamiltonii. Case presentation: An 82-year-old male patient who had been receiving CAPD therapy presented to an emergency department with complaints of abdominal pain and cloudy dialysate that had persisted for 2 days. The peritoneal dialysate was compatible with CAPD peritonitis, with white blood cell count of peritoneal effluent of 810/mm3 and neutrophils predominated (60%). Two days after culture on blood agar medium, nonhemolytic pink mucoid colonies showed, with cells showing Gram-negative, nonspore-forming rods with a few longer and larger bacilli than usual were found. We also performed biochemical tests and found negative responses in K/K on the triple sugar iron test and H2S and equivocal (very weak) response in the motility test, but positive responses to catalase, oxidase, and urease tests. The partial sequence of the 16S rRNA gene of a bacterium detected by peritoneal fluid culture was utilized for a Basic Local Alignment Search Tool search, which revealed that the organism was H hamiltonii. Intraperitoneal antibiotics were administered for 21 days, and the patient was discharged without clinical problems. Conclusion: We present here the first case report of CAPD-related peritonitis caused by H hamiltonii, which was identified using molecular biological techniques. Although guidelines do not exist for the treatment of infections caused by this organism, conventional treatment for Gram-negative organisms could be effective. PMID:27893682

    Pediatric peritoneal dialysis (PD) patients are at risk for acute peritonitis. One risk factor is accidental exposure of the catheter to a non-sterile surface. We studied catheter exposures in 17 pediatric patients receiving PD who developed 16 holes and 12 other accidental exposures. The rate of exposures was 3.7 events/100 patient-months. After exposure, the mean counts (+ or - standard error) of white blood cells (WBC), red blood cells, and neutrophils were 39.8 + or - 19.3, 9.5 + or - 7.1, and 24.2 + or - 5.3/mm(3), respectively. There was a trend towards higher peritoneal fluid WBC in patients with holes than in those with exposures (60.1 + or - 34.8 vs. 15.4 + or - 5.1/mm(3), respectively; p = 0.2). The initial peritoneal fluid WBC count was significantly higher if there was a positive culture than a negative culture (165.0 + or - 132.6 vs. 20.3 + or - 6.4/mm(3), respectively; p = 0.01). The percentage of neutrophils was higher in patients with a positive culture than in those with a negative culture (54.7 + or - 14.1 vs. 19.1 + or - 4.9%, respectively; p = 0.01). Of the 28 patients, 27 received a single dose of intravenous antibiotics, as per the protocol at that time. Among those treated, 7% developed a positive culture (all staphylococcal species) while 93% had a negative culture. We conclude that following accidental exposure of the peritoneal dialysis catheter: (1) the prevalence of peritonitis is low; (2) measuring peritoneal fluid WBC provides treatment guidance; (3) if treatment is initiated, it should be applied intraperitoneally and include activity against Gram-positive organisms.

    Due to ongoing limitations in the availability and timeliness of kidney transplantation, most patients with end-stage renal disease (ESRD) require some form of dialysis during their lifetime. Worldwide, ESRD patients most commonly receive hemodialysis (HD) or one of two forms of peritoneal dialysis (PD), continuous ambulatory PD (CAPD) or automated PD (APD). In this review, we analyze the data available from the last several decades on overall survival associated with HD as compared to PD as well as with CAPD compared to APD. Because of the inherent difficulty in randomly assigning patients to different dialysis modalities, the survival data available are virtually all observational and fraught with many confounding factors and limitations. However, over the last 10 – 15 years as overall survival of dialysis patients has steadily improved and statistical methods to analyze observational data have evolved, a pattern of virtual equivalence in survival among patients on HD vs. PD and on CAPD vs. APD has emerged. As such, impact upon lifestyle and upon quality of life likely should remain the predominant factors in guiding nephrologists and their patients in their choice of dialysis modality. PMID:25345384

    High mobility group box 1 (HMGB1), a DNA-binding nuclear protein, has been implicated as an endogenous danger signal in the pathogenesis of infection diseases. However, the potential role and source of HMGB1 in the peritoneal dialysis (PD) effluence of patients with peritonitis are unknown. First, to evaluate HMDB1 levels in peritoneal dialysis effluence (PDE), a total of 61 PD patients were enrolled in this study, including 42 patients with peritonitis and 19 without peritonitis. Demographic characteristics, symptoms, physical examination findings and laboratory parameters were recorded. HMGB1 levels in PDE were determined by Western blot and ELISA. The concentrations of TNF-α and IL-6 in PDE were quantified by ELISA. By animal model, inhibition of HMGB1 with glycyrrhizin was performed to determine the effects of HMGB1 in LPS-induced mice peritonitis. In vitro, a human peritoneal mesothelial cell line (HMrSV5) was stimulated with lipopolysaccharide (LPS), HMGB1 extracellular content in the culture media and intracellular distribution in various cellular fractions were analyzed by Western blot or immunofluorescence. The results showed that the levels of HMGB1 in PDE were higher in patients with peritonitis than those in controls, and gradually declined during the period of effective antibiotic treatments. Furthermore, the levels of HMGB1 in PDE were positively correlated with white blood cells (WBCs) count, TNF-α and IL-6 levels. However, pretreatment with glycyrrhizin attenuated LPS-induced acute peritoneal inflammation and dysfunction in mice. In cultured HMrSV5 cells, LPS actively induced HMGB1 nuclear-cytoplasmic translocation and release in a time and dose-dependent fashion. Moreover, cytosolic HMGB1 was located in lysosomes and secreted via a lysosome-mediated secretory pathway following LPS stimulation. Our study demonstrates that elevated HMGB1 levels in PDE during PD-related peritonitis, at least partially, from peritoneal mesothelial cells, which may be

    ♦ Objective: Little or no evidence is available on the impact of the first peritonitis episode on peritoneal transport characteristics. The objective of this study was to investigate the importance of the very first peritonitis episode and distinguish its effect from the natural course by comparison of peritoneal transport before and after infection. ♦ Participants: We analyzed prospectively collected data from 541 incident peritoneal dialysis (PD) patients, aged > 18 years, between 1990 and 2010. Standard Peritoneal Permeability Analyses (SPA) within the year before and within the year after (but not within 30 days) the first peritonitis were compared. In a control group without peritonitis, SPAs within the first and second year of PD were compared. ♦ Main outcome measurements: SPA data included the mass transfer area coefficient of creatinine, glucose absorption and peritoneal clearances of β-2-microglobulin (b2m), albumin, IgG and α-2-macroglobulin (a2m). From these clearances, the restriction coefficient to macromolecules (RC) was calculated. Also, parameters of fluid transport were determined: transcapillary ultrafiltration rate (TCUFR), lymphatic absorption (ELAR), and free water transport. Crude and adjusted linear mixed models were used to compare the slopes of peritoneal transport parameters in the peritonitis group to the control group. Adjustments were made for age, sex and diabetes. ♦ Results: Of 541 patients, 367 experienced a first peritonitis episode within a median time of 12 months after the start of PD. Of these, 92 peritonitis episodes were preceded and followed by a SPA within one year. Forty-five patients without peritonitis were included in the control group. Logistic reasons (peritonitis group: 48% vs control group: 83%) and switch to hemodialysis (peritonitis group: 22% vs control group: 3%) were the main causes of missing SPA data post-peritonitis and post-control.

    The main causes of death in patients undergoing dialysis are cardiovascular diseases. Their presence is related to the nutritional status of patients treated with peritoneal dialysis, and has a predicted value in this kind of patient. Long-term therapy entails unfavourable changes, from which a clinically significant complication is protein-energy malnutrition and intensification of inflammatory processes. The aim of the study was to assess the nutritional status of patients with chronic kidney disease treated with peritoneal dialysis based on anthropometric, biochemical parameters analysis, a survey, as well as the determination of changes in measured parameters occurring over time. The study involved 40 people undergoing peritoneal dialysis (PD) and 30 healthy people. For dialyzed patients testing material was collected twice, every 6 months. Proteins, albumins, prealbumins, C-reactive protein and glucose levels were measured. Anthropometric measurements included body height, body weight, triceps skinfold and subscapular skinfold thickness. Body mass index (BMI) value and exponent of tissue protein source were calculated. The examined patients completed the questionnaire, which included, among other factors, the daily intake of nutrients, and lifestyle information. During the 6 month observation of the PD group a stastically significant increase in the energy value of intake food and amount of calories intake from carbohydrates was found. Analysis of nutritional status dependent on the BMI showed that overweight and obese patients are characterized by higher concentrations of the C-reactive protein and glucose, as well as lower concentrations of prealbumin compared to patients with normal body weight. At the same time, the energy value of food and the amount of protein in the group with BMI > 25 were smaller than in the other groups. During the 6 month observation a decrease the concentration of prealbumin and an increase in C-reactive protein in BMI > 25 group

    The clinical aspects of peritonitis were reviewed in 83 patients treated with continuous ambulatory or continuous cyclic peritoneal dialysis between May 1978 and April 1988. Peritonitis occurred in 50 patients whose mean duration of dialysis was 17.8 months, but not in 33 patients with a mean duration of dialysis of 10.4 months. The mean time from starting dialysis to the first episode of peritonitis was 7.1 months. The peritonitis rate was lower for continuous cyclic than for continuous ambulatory peritoneal dialysis (1 episode per 12.9 vs. 1 episode per 8.1 patient months, respectively). In 39% of the episodes, gram stain of the dialysate was positive. The dialysate leukocyte count was higher in gram-negative than in gram-positive peritonitis. Seventy percent of the peritonitis episodes were gram positive, and Staphylococcus aureus was predominant. Only 1 of the 7 diapered infants had gram-negative organisms associated with peritonitis. Catheters were replaced in 48 cases, 26 because of infection. Sixty-nine percent of the patients were cured with antibiotic therapy alone. Although peritonitis was associated with a mortality rate of 1.2%, peritoneal dialysis remains the favored dialytic mode for children.

    ♦ Objective: About half the patients on peritoneal dialysis (PD) in China need to be assisted by family members or home assistants. We explored whether these patients have a higher risk for peritonitis and death compared with self-care PD patients. ♦ Methods: We prospectively followed 313 incident PD patients until death or censoring. This cohort was divided into assisted and self-care PD groups according to the independence of bag exchange. Data on baseline demographics, Charlson comorbidity index, biochemistry, and residual renal function were recorded during the first 3 – 6 months. The outcome variables were first episode of peritonitis and all-cause mortality. ♦ Results: Of the 313 patients in this cohort study, 122 needed assistance in performing bag exchanges (86 from a family member, 36 from a home assistant); the remaining 191 patients did not need assistance. During a follow-up period averaging 44.5 months, 122 patients developed a first episode of peritonitis, and 135 patients died. Compared with patients having a family assistant, those with a home assistant had similar peritonitis-free and survival times, but a higher risk of mortality after adjustments for variables such as age, sex, Charlson comorbidity score, hemoglobin, serum albumin, and residual renal function. Furthermore, compared with self-care patients, assisted patients overall had a similar peritonitis-free time, but a higher risk of mortality, even after adjusting for covariates. ♦ Conclusions: Based on our single-center experience in China, we conclude that assisted PD is a good option for patients with poor self-care ability. This result provides evidence for recruiting patients who need assistance to PD programs in China. PMID:21632447

    Acute renal failure (ARF) is a common complication in infants who undergo cardiac surgery in the intensive care unit. We report on a modified drainage catheter used in peritoneal dialysis (PD) for the treatment of ARF associated with cardiac surgery in infants. Thirty-nine infants with congenital heart disease undergoing cardiac surgery who developed ARF at our center between January 2009 and January 2012 were assessed. A modified drainage catheter for PD was used in these infants. Their demographic, clinical, and surgical data were analyzed. Thirty infants with ARF were cured by PD, and the other 9 died in the first 48 hours because of the severity of the acute cardiac dysfunction. All these infants were dependent upon mechanical ventilation during the postoperative period and used vasoactive drugs. In the survival group, the interval between the procedure and initiation of PD was 13.6 ± 6.5 (range, 6-30) hours. PD duration was 3.9 ± 0.9 (3-6) days. Minor complications were encountered in some patients (asymptomatic hypokalemia, hyperglycemia, and thrombocytopenia). These complications were readily treated by drugs or resolved spontaneously. Hemodynamics, cardiac function, and renal function improved significantly during PD. These data suggest that PD using a modified drainage catheter for ARF after cardiac surgery in infants is safe, feasible, inexpensive, and yields good results.

    Mycobacterium fortuitum, an environmental organism, is capable of producing a variety of clinical infections such as cutaneous infections, abscesses and nosocomial infections. Rarely, it has been a documented as a cause of peritonitis in patients receiving continuous ambulatory peritoneal dialysis (CAPD). Continuous Ambulatory Peritoneal dialysis (CAPD) is one of the treatment options which are used for patients with end-stage renal disease (ESRD). Although peritonitis rates have declined in parallel with advances in peritoneal dialysis (PD) technology, peritonitis remains a leading complication of CAPD and it is the major cause for transfer to other methods of dialysis. We are reporting a case of M. fortuitum peritonitis in a patient who was undergoing CAPD, which was successfully treated. This case emphasizes the importance of mycobacterial cultures in patients with CAPD-associated peritonitis, whose routine cultures may yield no organisms.

    Consideration of specific pediatric aspects is essential to achieve adequate peritoneal dialysis (PD) treatment in children. These are first of all the rapid growth, in particular during infancy and puberty, which must be accompanied by a positive calcium balance, and the age dependent changes in body composition. The high total body water content and the high ultrafiltration rates required in anuric infants for adequate nutrition predispose to overshooting convective sodium losses and severe hypotension. Tissue fragility and rapid increases in intraabdominal fat mass predispose to hernia and dialysate leaks. Peritoneal equilibration tests should repeatedly been performed to optimize individual dwell time. Intraperitoneal pressure measurements give an objective measure of intraperitoneal filling, which allow for an optimized dwell volume, that is, increased dialysis efficiency without increasing the risk of hernias, leaks, and retrofiltration. We present the concept of adapted PD, that is, the combination of short dwells with low fill volume to promote ultrafiltration and long dwells with a high fill volume to improve purification within one PD session. The use of PD solutions with low glucose degradation product content is recommended in children, but unfortunately still not feasible in many countries. PMID:21761001

    Management of chronic uremia in elderly patients presents several clinic and organizational difficulties. Hemodialysis (HD) and chronic peritoneal dialysis (CPD) are both available for the elderly, and the choice depends on the individual, clinical and familial conditions. Several reports have compared the outcomes for older patients treated by HD or peritoneal dialysis, with those for younger or older patients undergoing peritoneal dialysis. CPD is a successful dialysis option for elderly patients, in both patient and technique survival terms. All nutritional parameters are of pivotal importance. Several barriers, such as medical and social factors, physician bias, late referral and education irrespective of the needs of older patients, influence the choice of CPD. The development of assisted peritoneal dialysis, using community-based nurses or health care assistants, can overcome some of the barriers and enable frail older patients to have home-based dialysis treatment. Increasing age is associated with higher peritonitis rates among patients who started CPD in the 1990s, while age is not associated with peritonitis in more recent CPD cohorts, and no greater frequency of adverse outcomes of peritonitis has been seen among those who began CPD after the year 2000. In elderly dialysis patients, the management of quality of life (QOL) is important as well as adequacy of dialysis, nutritional status and survival rate. To obtain a good standard of QOL, it is essential to select carers who are properly educated and who can access an adequate support system, both physical and psychological, to help them cope with their burden.

    The peritoneal equilibration test (PET) is the gold standard method for defining peritoneal membrane permeability and for prescribing peritoneal dialysis (PD) therapy on an individual basis. However, it is laborious, consumes nursing time, and requires many hours to be performed. Therefore, several authors have attempted to validate a short PET protocol, with controversial results. To evaluate the concordance between the 2-h (short) and 4-h (classical) peritoneal equilibrium test, a prospective observational protocol was applied in three PD centers (Mexico, Chile, and Uruguay) between July 1, 2008 and July 31 2009. PET protocol: the night prior to the test, each patient received five exchanges, 1 h each, at the same glucose concentration as previously used. Afterwards, a 2.5% glucose dialysis solution was used for a dwell time of 4 h. Exchange fill volume was 1,100 ml/m2 body surface area. The next morning, the 4-h dwell was drained, and Dianeal 2.5% was infused. Three dialysate samples at 0, 2, and 4 h were obtained. A single blood sample was obtained at 120 min. Creatinine D/P and glucose D/D0 ratios were calculated at hours 0, 2, and 4. Patients were categorized as low, low average, high average, or high transporters according creat D/P and gluc D/D0 results. Pearson and Kappa test were used for numerical and categorical correlations, respectively, and p<0.05 was considered significant. Eighty-seven PET studies were evaluated in 74 patients, 33 males, age 11.1+/-5.05 years old. A positive linear correlation of 92% between 2 and 4-h creat D/P and 80% between 2 and 4-h gluc D/D0 (p<0.001) was founded. The Kappa test showed a significant concordance between creat D/P and gluc D/D0 categories at 2 and 4 h (p<0.001). When analyzing cut-off-value categories, creat D/P was founded to be lower and gluc D/D0 higher than other experiences. This multicentric prospective study strongly suggests that PET obtained at 2 h and 4 h, based on either creatinine or glucose

    ♦ Background: Chronic kidney disease is a major public health problem in sub-Saharan Africa (SSA), which encompasses 70% of the least-developed countries in the world. Most people in SSA have no access to any form of renal replacement therapy (RRT). Given its ease of performance and patient independence, peritoneal dialysis (PD) should be an ideal form of RRT in SSA, but several complex and interdependent factors make PD a difficult option in SSA. The present review describes the practice of PD in SSA, with emphasis on Cape Town, South Africa. ♦ Methods and Results: After a review of the recent PubMed literature on RRT in SSA and an appraisal of nephrology practice in South Africa, factors that make the provision of RRT (especially PD) a challenge in SSA include the low number of qualified health care workers, socio-demographic issues (poor housing, electricity, and water supplies), and the cost of PD fluids in the region. Although South Africa has the largest PD population in all of SSA, the growth of PD in South Africa is specifically impeded by the system of RRT rationing, which favors HD; the methods of funding for dialysis and for remuneration of doctors in private practice; and many other socio-economic factors. The peritonitis rate remains relatively high, and it is a significant contributor to morbidity in PD patients in Cape Town. ♦ Conclusions: In many parts of SSA, PD could be the main dialysis modality. However, African governments must start taking responsibility for their people by providing adequate funds for renal replacement programs. Attempts to produce PD fluids locally and to train and educate health care workers will greatly improve the use of PD as a RRT option in SSA. PMID:22641735

We treated with this technique 28 patients with end stage renal disease (ESRD), between 1981-1988; (24 adults, 8 of them with diabetic nephropathy (6 non insulin dependent diabetic patients and 4 children) for 3 to 36 months. IPD was well tolerated. The extracellular volume control, haematocrit and plasma protein values, as well as, ac-base equilibrium nutritional status, ureic nitrogen and creatinine plasma levels, were fully satisfactory. There was statistical difference only in the Na+ (p less than 0.001), alkaline phosphatases (p less than 0.005), glucose (p less than 0.05) plasma values and glycosylated hemoglobin (p less than 0.05), between diabetics and non diabetics group. The peritonitis rate was 0.065 and 0.074 peritonitis/patients-month; respectively (NS) and were caused by Gram (-) bacteria. St Aureus and St Epidermides. The survival curves of patients and method, in both groups, were similar (NS). We conclude IPD is a good alternative of therapy for ESRD, also for diabetics patients, whom haven't got more infection rate than non diabetics patients.

    The Stoke Renal Unit has been at the forefront of peritoneal dialysis (PD) research for much of the past two decades. Central to this work is the PD cohort study, which was started in 1990 and is based on regular outpatient measurements of peritoneal and clinical function, correlating these with long-term outcomes. It has provided a wealth of information on risk factors for morbidity and mortality in patients on PD, the most significant being demonstration of the effects of time and dialysate glucose exposure on changes to the peritoneal membrane, as evidenced by increases in small solute transport. Early on, the study confirmed the adverse relationship between high small-solute transport status and outcome but more recently suggested that this relationship no longer held with modern techniques for managing patients on PD. Central themes of the PD research in Stoke have included evaluation of euvolemia, the importance of ultrafiltration and how best to achieve it, and detailed assessments of transmembrane water movement. The work has included the study of sodium removal and the use of novel low sodium dialysates. More recently, attention has turned to the significance of impaired ultrafiltration capacity in patients on PD as a sign of structural membrane damage. It is hoped that further work in this area will identify preventive strategies.

    Patient satisfaction is an important aspect of dialysis care, only recently evaluated in clinical studies. We developed a tool to assess peritoneal dialysis (PD) customer satisfaction, and sought to evaluate and validate the Customer Satisfaction Questionnaire (CSQ), quantifying PD patient satisfaction. The CSQ included questions regarding administrative issues, Delivery Service, PD Training, Handling Requests, and transportation. The study was performed using interviews in all Hungarian Fresenius Medical Care dialysis centers offering PD. CSQ results were compared with psychosocial measures to identify if patient satisfaction was associated with perception of social support and illness burden, or depression. We assessed CSQ internal consistency and validity. Factor analysis explored potential underlying dimensions of the CSQ. One hundred and thirty-three patients treated with PD for end-stage renal disease for more than 3 months were interviewed. The CSQ had high internal consistency. There was high patient satisfaction with customer service. PD patient satisfaction scores correlated with quality of life (QOL) and social support measures, but not with medical or demographic factors, or depressive affect. The CSQ is a reliable tool to assess PD customer satisfaction. PD patient satisfaction is associated with perception of QOL. Efforts to improve customer satisfaction may improve PD patients' quantity as well as QOL.

    Peritoneal dialysis (PD) catheters may be inserted blindly, surgically, and either by laparoscopic, peritoneoscopic, or fluoroscopic approach. A modified fluoroscopic technique by adding ultrasound-assistance was performed in the present study to ensure entry into the abdominal cavity under direct ultrasound visualization. From March 2005 to May 2007, ultrasound-fluoroscopic guided placement of PD catheters was attempted in 32 end-stage renal disease (ESRD) patients. Preoperative evaluation was performed on all patients prior to the procedure. After initial dissection of the subcutaneous tissue anterior to the anterior rectus sheath, the needle was inserted into the abdominal cavity under the guidance of ultrasound. The position of the epigastric artery was also examined using ultrasonography to avoid the risk of arterial injury. PD catheters were successfully placed in 31 of the 32 ESRD patients using this technique. In all of these patients, the needle could be seen entering the abdominal cavity using an ultrasound. In one patient the procedure was abandoned because of bowel puncture by the micro-puncture needle that was inadvertently advanced into a loop of bowel. This patient did not develop acute abdomen nor needed any intervention. One patient died 4 days after placement of the catheter of unrelated causes. One patient was started on acute peritoneal dialysis the same day of catheter placement without any complications. The rest of the patients started peritoneal dialysis within 2-6 weeks of catheter placement. None of the patients had bleeding related to arterial injury as ultrasound was able to visualize the epigastric artery. Our experience shows that ultrasound-fluoroscopic technique is minimally invasive and allows for accurate assessment of the entry into the abdominal cavity. This technique can avoid the risk of vascular injury altogether.

    Peritoneal dialysis (PD) is an important therapy for patients with end-stage kidney disease and is used in more than 200,000 such patients globally. However, its value is often limited by the development of infections such as peritonitis and exit-site and tunnel infections. Multiple strategies have been developed to reduce the risk of peritonitis including antibiotics, topical disinfectants to the exit site and antifungal agents. However, the effectiveness of these strategies has been variable and are based on a small number of randomised controlled trials (RCTs). The optimal preventive strategies to reduce the occurrence of peritonitis remain unclear.This is an update of a Cochrane review first published in 2004. To evaluate the benefits and harms of antimicrobial strategies used to prevent peritonitis in PD patients. We searched the Cochrane Kidney and Transplant's Specialised Register to 4 October 2016 through contact with the Information Specialist using search terms relevant to this review. Studies contained in the Specialised Register are identified through search strategies specifically designed for CENTRAL, MEDLINE, and EMBASE; handsearching conference proceedings; and searching the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. RCTs or quasi-RCTs in patients receiving chronic PD, which evaluated any antimicrobial agents used systemically or locally to prevent peritonitis or exit-site/tunnel infection were included. Two authors independently assessed risk of bias and extracted data. Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratio (RR) with 95% confidence intervals (CI). Thirty-nine studies, randomising 4435 patients, were included. Twenty additional studies have been included in this update. The risk of bias domains were often unclear or high; risk of bias was judged to be low in 19 (49%) studies for random sequence generation, 12 (31%) studies for

    Objective: to analyze the complications related to peritonitis and catheter exit-site infections, in patients on peritoneal dialysis at home. Method: quantitative and cross-sectional study, carried out with 90 patients on peritoneal dialysis at home, in a municipality in the Northeast region of Brazil. For data collection, it was used two structured scripts and consultation on medical records. Descriptive analysis and comparison tests among independent groups were used, considering p<0.05 as level of statistical significance. Results: by comparing the frequency of peritonitis and the length of treatment, it was found that patients over two years of peritoneal dialysis were more likely to develop peritonitis (X²=6.39; p=0.01). The number of episodes of peritoneal catheter exit-site infection showed association with the length of treatment (U=224,000; p=0.015). Conclusion: peritonitis and catheter exit-site infection are associated with the length of treatment. PMID:26487141

    Peritonitis is a major complication of peritoneal dialysis, but the relationship between peritonitis and mortality among these patients is not well understood. In this case-crossover study, we included the 1316 patients who received peritoneal dialysis in Australia and New Zealand from May 2004 through December 2009 and either died on peritoneal dialysis or within 30 days of transfer to hemodialysis. Each patient served as his or her own control. The mean age was 70 years, and the mean time receiving peritoneal dialysis was 3 years. In total, there were 1446 reported episodes of peritonitis with 27% of patients having ≥2 episodes. Compared with the rest of the year, there were significantly increased odds of peritonitis during the 120 days before death, although the magnitude of this association was much greater during the 30 days before death. Compared with a 30-day window 6 months before death, the odds for peritonitis was six-fold higher during the 30 days immediately before death (odds ratio, 6.2; 95% confidence interval, 4.4–8.7). In conclusion, peritonitis significantly associates with mortality in peritoneal dialysis patients. The increased odds extend up to 120 days after an episode of peritonitis but the magnitude is greater during the initial 30 days. PMID:22626818

    One of the main goals of dialysis is the control of extracellular volume, because inadequate sodium and fluid removal result in fluid overload and increased mortality. In the present study, we evaluated the roles of continuous ambulatory peritoneal dialysis (CAPD), continuous cycling peritoneal dialysis (CCPD), and the use of icodextrin on sodium removal in 29 patients (n = 18 on CAPD, n = 11 on CCPD). Daily removal of sodium by each modality and dialysis adequacy by Kt/V and creatinine clearance were evaluated. A significantly higher amount of sodium was removed in CAPD patients than in CCPD patients, although peritoneal dialysis clearances were lower in CAPD, and no difference in daily ultrafiltration was observed between the modalities. In the CAPD group, patients using icodextrin for the long dwell showed significantly increased 24-hour sodium removal (218 +/- 65 mmol/L) as compared with patients not using icodextrin (96.3 +/- 58 mmol/L, p < 0.001); they also showed increased daily ultrafiltration (1685 +/- 302 mL vs. 717 +/- 440 mL, p < 0.001). In the CCPD group, 8 patients were using icodextrin for the long dwell, and they showed significantly increased sodium removal only for the day exchange (43 +/- 49 mmol/L) as compared with patients not using icodextrin (-60 +/- 6, p < 0.001). Hypertension was less common in the CAPD patients than in the CCPD patients. These results indicate that CAPD is a more efficient modality than CCPD for sodium removal. Icodextrin is an effective tool not only for increasing adequacy, but also for removing more sodium in both modalities.

    We aimed in this study to explore how lower-protein diet would affect dialysis adequacy in anuric peritoneal dialysis (PD) patients. Patients' demographic features were collected, namely age, gender, weight, height, underlying renal disease, and time on PD. Urea kinetic model was used to assess solute clearance. A consecutive 3-day dietary record was collected to evaluate dietary protein intake (DPI), and normalized protein nitrogen appearance (nPNA) was also calculated to reflect protein intake. Blood samples were collected to measure hemoglobin and biochemistry. Patient's nutritional status was assessed by biochemistry, handgrip strength, and subjective global assessment (SGA). Body fluid distribution was measured by body composition monitor. Patients were 60.8 ± 14.92 years old, and the time on PD was 40.15 ± 22.90 months. Daily prescribed dialysis dose was 7,178 ± 1,326 mL. Kt/V was 1.6 ± 0.32. DPI was 0.8 ± 0.25 g/kg/day. nPNA was 0.9 ± 0.21 g/kg/day. Serum albumin was 39.42 ± 4.83 g/L. Prevalence of malnutrition (assessed by SGA) was 20.2 %. Serum phosphate and serum bicarbonate were 1.68 ± 0.47 and 27.16 ± 3.49 mmol/L, respectively. Systolic blood pressure and diastolic blood pressure were 123.4 ± 20.0 and 74.2 ± 12.6 mmHg, respectively. Patients with nPNA less than 0.6 had significantly lower serum albumin concentrations than the average, and patients with nPNA more than 1.2 g/kg/day had significantly higher levels of serum phosphate and serum urea than the average. Our study suggested that anuric PD patients could achieve adequate dialysis even under lower solute clearance. And lower-protein diet contributed largely to adequate dialysis in these patients.

    PD (peritoneal dialysis) is an established mode of renal replacement therapy, based on the exchange of fluid and solutes between blood in peritoneal capillaries and a dialysate that has been introduced into the peritoneal cavity. The dialysis process involves diffusive and convective transports and osmosis through the PM (peritoneal membrane). Computer simulations predicted that the PM contains ultrasmall pores (radius <3 A, 1 A=10(-10) m), responsible for up to 50% of UF (ultrafiltration), i.e. the osmotically driven water movement during PD. Several lines of evidence suggest that AQP1 (aquaporin-1) is the ultrasmall pore responsible for transcellular water permeability during PD. Treatment with corticosteroids induces the expression of AQP1 in the PM and improves water permeability and UF in rats without affecting the osmotic gradient and permeability for small solutes. Studies in knockout mice provided further evidence that osmotically driven water transport across the PM is mediated by AQP1. AQP1 and eNOS (endothelial nitric oxide synthase) show a distinct regulation within the endothelium lining the peritoneal capillaries. In acute peritonitis, the up-regulation of eNOS and increased release of nitric oxide dissipate the osmotic gradient and prevent UF, whereas AQP1 expression is unchanged. These results illustrate the usefulness of the PM to investigate the role and regulation of AQP1 in the endothelium. The results also emphasize the critical role of AQP1 during PD and suggest that manipulation of AQP1 expression may be used to increase water permeability across the PM.

    Headache is among most frequently encountered neurological symptom during hemodialysis (HD), but still under investigated in peritoneal dialysis (PD) patients. The aim of this study was to assess the incidence and clinical characteristics of dialysis headache (DH) in HD and PD patients. A total of 409 patients (91 on PD and 318 on HD) were interviewed using a structured questionnaire, designed according to the diagnostic criteria of the International Headache Classification of Headache Disorders from 2004. Patients with DH underwent a thorough neurological examination. DH was reported by 21 (6.6%) HD patients and 0 PD patients. PD patients had significantly lower serum sodium, potassium, calcium, phosphate, urea and creatinine, calcium-phosphate product, and diastolic blood pressure than HD patients. HD patients had significantly lower hemoglobin compared to PD patients. Primary renal disease was mostly parenchymal in HD patients, and vascular in PD patients. DH appeared more frequently in men, mostly during the third hour of HD. It lasted less than four hours, was bilateral, non-pulsating and without associated symptoms. Biochemical alterations may be implicated in the pathophysiology of DH. Specific features of DH might contribute to better understanding of this secondary headache disorder.

    A modified fluoroscopic technique by adding ultrasound-assistance ensuring entry into the abdominal cavity and avoiding the risk of epigastric artery injury under direct ultrasound visualization was recently published. This study demonstrated that the technique was minimally invasive and allowed for accurate assessment of entry into the abdominal cavity and avoidance of vascular injury. In the current analysis, we report the impact of this technique on hospital stay during a peritoneal dialysis (PD) catheter insertion. Twenty-six PD catheters have been placed on an outpatient basis using this technique. All catheter insertions were successful. Patients were discharge on the same day of the procedure. There were no procedure-related complication or related to short hospital stay. An ambulatory setting allows for a short hospital stay without compromising patient care. This brief paper explains in detail the pre, peri and postoperative period and follow-up.

    Sorbent regeneration of peritoneal dialysate has been shown to be feasible in experimental and preliminary clinical studies and provides a realistic basis for the optimization of dialysis therapy and the potential development of an ambulatory dialysis system. Peritoneal dialysis efficiency can be significantly enhanced by continuous dialysate flow techniques and the mass transfer of uremic solutes can be theoretically augmented by the increased dialysis time made possible by a wearable design. Further optimization of end stage renal failure therapy may be achieved by the combined use of various methods for blood purification.

    Many patients with end-stage renal disease have now been maintained for 5 years or more with continuous ambulatory peritoneal dialysis (CAPD). Viewed initially as an experimental alternative to be used only when hemodialysis was not feasible, CAPD is now seen as the treatment of choice in an increasing number of situations. CAPD is suitable for self-care. The main concern in the early years--peritonitis--is now less frightening and less frequent (one episode occurring every 18 patient-months as compared with every 8 initially), and this has allowed chronic complications of CAPD, such as malnutrition and loss of the peritoneum's capacity for ultrafiltration, to come to light. As would be expected, among patients of advanced age and those who have heart disease or diabetes, survival rates tend to be lower than among other CAPD patients. However, hypertension seems to be more easily controlled, pre-existing anemia can be significantly ameliorated, and young children grow more normally than they do with hemodialysis. Diabetes-related changes in vision stabilize in most CAPD patients, and control of the blood glucose level is good; insulin is administered intraperitoneally. CAPD is thus showing itself to be a feasible form of long-term treatment for end-stage renal disease. Images Fig. 1 PMID:6697277

    Automated peritoneal dialysis (APD) is important for the further penetration of PD in the dialysis marketplace. Long dwell, equilibration PD (CAPD) has limited applicability in many patients due to inadequate solute clearance or fast membrane transport characteristics. Providing large volumes of dialysate over circumscribed hours is highly labor intensive without an automated system. Early attempts at APD were crude but effective in reducing labor, which was generally provided by nursing staff. Later evolution of PD technology has been greatly accelerated by the microchip, and by miniaturization of components. Current generation machines allow individualized fill volumes, variable tidal volumes and additional daytime automated exchanges, teledialysis, memorized delivery control, and full portability. The ideal machine should not only be able to perform all treatment schedules, but it should also optimize the performance of a selected treatment strategy. Biocompatible solutions, improved osmotic agents, and sorbent technology are all adaptable to APD. The eventual evolution toward continuous flow PD will resolve many of the current problems with both CAPD and APD.

    Controversy still exists as to whether peritoneal dialysis (PD) treatment can be safely continued after herniotomy. Many nephrologists withhold PD treatment for several weeks after herniotomy for fear of dialysate leakage and hernia recurrence. Here, we report on 9 patients (2 women, 7 men) in whom herniotomy was performed for umbilical (n = 3), inguinal (n = 5), or cicatricial hernia (n = 2), or for open processus vaginalis (n = 2). Surgery was performed according to the Lichtenstein method with insertion of a polypropylene mesh and ligation of the hernia sac. In all patients, PD treatment was paused for the day of surgery and for 1-3 days postoperatively, depending on residual renal function. Over the next several days, low-volume (1.0-1.5 L), high-frequency (6 per day) exchanges were started. The patient's original PD regimen was gradually reinstated over the next 2-4 weeks. All patients recovered rapidly, with no uremia or dialysis-related complications. Particularly, no leakage and no hernia recurrence could be observed 3 months thereafter. None of the patients had to be hemodialyzed intercurrently. In conclusion, continuing a modified regimen of CAPD treatment after herniotomy seems to be safe, with excellent patient comfort.

    Background and objectives: Hyperphosphatemia is an independent risk factor for mortality in ESRD, but factors regulating phosphate clearance on peritoneal dialysis (PD) are incompletely understood. The objective of this study was to test the hypothesis that peritoneal phosphate clearance is better with continuous ambulatory PD (CAPD) as compared with continuous cyclic PD (CCPD) after adjusting for membrane transport status. Design, setting, participants, & measurements: In this cross-sectional and retrospective study, measurements of peritoneal phosphate clearance of 129 prevalent PD patients were reviewed. Patients were divided according to membrane transport status (high, high average, low average-low categories) and PD modality (CAPD or CCPD). Results: Among high transporters, peritoneal phosphate clearances were comparable in both modalities. However, treatment with CAPD was associated with increased peritoneal phosphate clearance compared with CCPD among high-average transporters (42.4 ± 11.4 versus 36.4 ± 8.3 L/wk/1.73 m2, P = 0.01), and low-average-low transporters (35.6 ± 5.9 versus 28.9 ± 11 L/wk/1.73 m2, P = 0.034). On multivariate linear regression, PD modality, membrane transport category, and peritoneal creatinine clearance, but not Kt/V urea, were independently associated with peritoneal phosphate clearance. Conclusions: Peritoneal phosphate clearance is determined by PD modality and membrane transport category, suggesting that PD regimes with longer dwell times may help control hyperphosphatemia in lower transporters.

    To study the effect of training methods on selected patient outcomes in peritoneal dialysis patients. Multi-center, longitudinal prospective quasi-experimental design study conducted over a 2-year period. Thirty-two Gambro Healthcare peritoneal dialysis (PD) home training programs in the United States. New patients starting PD were trained on PD technique and diet using either an adult learning theory-based curriculum in the experimental group (PG) or non-standardized conventional training programs in the control group (CG). Excluded were patients who were non-English speaking, legally blind without sighted caregiver, nursing home residents, and those with previous exposure to PD training. Information was collected by means of manual data collection tools and though the use of Gambro Healthcare computer system and was analyzed for statistical significance by Gambro Healthcare biostatistician. Compared with the CG, initial training took longer in the PG (PG = 29 hrs; CG = 22.6 hrs; p < .0001), and time required for retraining was less but not statistically significant (PG = 8.7 hrs; CG = 12.5 hrs; p = .1324). The peritonitis rate was less in the PG (28.2 per 1000 patient months) than in the CG (36.7 per 1000 patient months), but did not achieve statistical significance (p = .09783). Exit site infections (ESIs) were less in the PG than the CG (PG = 18.5; CG = 31.8; p = .00349). Dropout from PD to hemodialysis secondary to infection was less in the PG (1.6%) than in the CG (5.6%) (p = .0069). Measured on a scale with 4 being the best score, mean fluid balance scores in the PG were 3.41 compared to 3.25 in the CG (p < .0001), and mean compliance scores for the PG versus the CG were 3.62 and 3.52, respectively (p < .0001). Laboratory parameters between the two groups were significantly different only for Kt/V (PG = 2.4; CG = 2.3; p = 0.0107).

    Peritoneal dialysis therapy has increased in popularity since the end of the 1970s. This method provides a patient survival rate equivalent to hemodialysis and better preservation of residual renal function. However, technique failure by peritonitis, and ultrafiltration failure, which is a multifactorial complication that can affect up to 40% of patients after 3 years of therapy. Encapsulant peritoneal sclerosis is an extreme and potentially fatal manifestation. Causes of inflammation in peritoneal dialysis range from traditional factors to those related to chronic kidney disease per se, as well as from the peritoneal dialysis treatment, including the peritoneal dialysis catheter, dialysis solution, and infectious peritonitis. Peritoneal inflammation generated causes significant structural alterations including: thickening and cubic transformation of mesothelial cells, fibrin deposition, fibrous capsule formation, perivascular bleeding, and interstitial fibrosis. Structural alterations of the peritoneal membrane described above result in clinical and functional changes. One of these clinical manifestations is ultrafiltration failure and can occur in up to 30% of patients on PD after five years of treatment. An understanding of the mechanisms involved in peritoneal inflammation is fundamental to improve patient survival and provide a better quality of life. PMID:22547910

    The clinical courses and long-term outcomes of viridans streptococcus (VS) peritoneal dialysis (PD) peritonitis remain unclear. We conducted a retrospective analysis of all PD patients in a single center with gram-positive cocci (GPC) peritonitis between 2005 and 2011, and divided them into 3 groups: VS, other streptococci and other GPC (apart from VS). Clinical characteristics and outcomes of the VS group were compared with the other streptococci and other GPC groups, with prognostic factors determined. A total of 140 patients with 168 episodes of GPC peritonitis (44% of all peritonitis) were identified over 7 years. Among these, 18 patients (13%) developed VS peritonitis, while 14 patients (10%) developed other streptococcal peritonitis. Patients with VS peritonitis had a high cure rate by antibiotic alone (94%), despite a high polymicrobial yield frequency (28%). We found that VS peritonitis carried a lower risk of Tenckhoff catheter removal and relapsing episodes than other GPC peritonitis (6% vs 11%), and a lower mortality than other streptococci peritonitis (0% vs 7%). However, after the index peritonitis episodes, VS, other streptococci, and other GPC group had a significantly increased peritonitis incidence compared with the period before the index peritonitis (all p < 0.01). Patients with VS peritonitis had a significantly higher incidence of refractory peritonitis compared with other streptococci or other GPC peritonitis in the long term (both p < 0.01). VS poses a higher risk of subsequent refractory peritonitis after the index episode as compared with other streptococcal or GPC peritonitis. It might be prudent to monitor the technique of these patients with VS peritonitis closely to avoid further peritonitis episodes. Copyright © 2015 International Society for Peritoneal Dialysis.

    We present a case where Bacillus cereus was determined to be the causative agent of relapsing peritonitis in a patient on continuous ambulatory peritoneal dialysis (CAPD). The patient, a 70-year-old man from the Faroe Islands, was admitted with relapsing peritonitis four times over a 3-month period. Peritoneal cultures were positive for growth of B. cereus, a rare bacterial cause of peritonitis. The cultures demonstrated susceptibility to vancomycin, and therefore the patient was treated with intraperitoneal vancomycin, intraperitoneal gentamycin and oral ciprofloxacin. As a result of the relapsing B. cereus peritonitis diagnosis and a CT scan showing contraction of the peritoneum after longstanding inflammation, the peritoneal catheter was removed and the patient converted to haemodialysis. To date, the patient has not been readmitted due to peritonitis. A lack of proper hygiene when changing the dialysis bag was the suspected source of infection with B. cereus. 2016 BMJ Publishing Group Ltd.

    The principal complications of continuous ambulatory peritoneal dialysis (CAPD), namely malposition of the dialysis catheter, peritonitis, exit site infection, leakage of dialysis fluid, sclerosing peritonitis, and renal cysts and tumors, are considered in this article. The techniques that are used to reposition displaced dialysis catheters and extend the duration of dialysis are described. The role of imaging in establishing the diagnosis of peritonitis is relatively small. However, both computed tomography (CT) and ultrasound may be used to identify loculation of fluid and localized sites of sepsis, and permit percutaneous drainage. Ultrasonography of the catheter track through the percutaneous tissues allows identification of pericatheter collections in patients with exit-site infection. The technique of CT peritoneography is helpful in establishing sites of dialysis fluid leakage. These commonly occur at the site of entry of the dialysis catheter, through abdominal incisions, or along the patent tunica vaginalis into the scrotum. The appearances on CT of sclerosing peritonitis reflect pathologic changes and are characterized by the presence of peritoneal thickening and calcification. Bowel obstruction, which may develop in sclerosing peritonitis, can be identified on abdominal radiographs or barium studies of the gastrointestinal tract. Acquired renal cystic disease and renal carcinomas occur in a significant proportion of patients undergoing CAPD. Ultrasound is the investigation of first choice in the identification and clarification of the pathology (cystic or solid) of suspected renal masses.

    Pharmacokinetics of icodextrin in peritoneal dialysis patients. Icodextrin is a glucose polymer osmotic agent used to provide sustained ultrafiltration during long peritoneal dialysis (PD) dwells. A number of studies have evaluated the steady-state blood concentrations of icodextrin during repeated use; however, to date the pharmacokinetics of icodextrin have not been well studied. The current study was conducted to determine the absorption, plasma kinetics and elimination of icodextrin and metabolites following a single icodextrin exchange. Thirteen PD patients were administered 2.0 L of solution containing 7.5% icodextrin for a 12-hour dwell. Icodextrin (total of all glucose polymers) and specific polymers with degrees of polymerization ranging from two to seven (DP2 to DP7) were measured in blood, urine and dialysate during the dwell and after draining the solution from the peritoneal cavity. A median of 40.1% (60.24 g) of the total administered dose (150 g) was absorbed during the 12-hour dwell. Plasma levels of icodextrin and metabolites rose during the dwell and declined after drain, closely corresponding to the one-compartment pharmacokinetic model assuming zero-order absorption and first-order elimination. Peak plasma concentrations (median C peak = 2.23 g/L) were observed at the end of the dwell (median Tmax = 12.7 h) and were significantly correlated with patients' body weight (R2 = 0.805, P < 0.001). Plasma levels of icodextrin and metabolites returned to baseline within 3 to 7 days. Icodextrin had a plasma half-life of 14.73 hours and a median clearance of 1.09 L/h. Urinary excretion of icodextrin and metabolites was directly related to residual renal function (R2 = 0.679 vs. creatinine clearance, P < 0.01). In the nine patients with residual renal function, the average daily urinary excretion of icodextrin was 473 +/- 77 mg per mL of endogenous renal creatinine clearance. Icodextrin metabolites DP2 to DP4 were found in the dialysate of subsequent

    ♦ Background, Objectives, and Methods: Hospitalization and mortality rates in pediatric dialysis patients remain unacceptably high. Although studies have associated the presence of comorbidities with an increased risk for death in a relatively small number of pediatric dialysis patients, no large-scale study had set out to describe the comorbidities seen in pediatric dialysis patients or to evaluate the impact of those comorbidities on outcomes beyond the newborn period. In the present study, we evaluated the prevalence of comorbidities in a large international cohort of pediatric chronic peritoneal dialysis (CPD) patients from the International Pediatric Peritoneal Dialysis Network registry and began to assess potential associations between those comorbidities and hospitalization rates and mortality. ♦ Results: Information on comorbidities was available for 1830 patients 0 - 19 years of age at dialysis initiation. Median age at dialysis initiation was 9.1 years [interquartile range (IQR): 10.9], median follow-up for calculation of hospitalization rates was 15.2 months (range: 0.2 - 80.9 months), and total follow-up time in the registry was 2095 patient-years. At least 1 comorbidity had been reported for 602 of the patients (32.9%), with 283 (15.5%) having cognitive impairment; 230 (12.6%), motor impairment; 167 (9.1%), cardiac abnormality; 76 (4.2%), pulmonary abnormality; 212 (11.6%), ocular abnormality; and 101 (5.5%), hearing impairment. Of the 150 patients (8.2%) that had a defined syndrome, 85% had at least 1 nonrenal comorbidity, and 64% had multiple comorbidities. The presence of at least 1 comorbidity was associated with a higher hospitalization rate [hospital days per 100 observation days: 1.7 (IQR: 5.8) vs 1.2 (IQR: 3.9), p = 0.001] and decreased patient survival (4-year survival rate: 73% vs 90%, p < 0.0001). ♦ Conclusions: Nearly one third of pediatric CPD patients in a large international cohort had at least 1 comorbidity, and multiple

    To identify patients with end-stage renal disease treated by peritoneal dialysis (PD) who had zero body fat (BF) as determined by analysis of body composition using anthropometric formulas estimating body water (V) and to compare nutritional parameters between these patients and PD patients whose BF was above zero. Body weight (W) consists of fat-free mass (FFM) and BF. Anthropometric formulas for calculating V allow the calculation of FFM as V/0.73, where 0.73 is the water fraction of FFM at normal hydration. Wasting from loss of BF has adverse survival outcomes in PD. Advanced wasting was defined as zero BF when V/0.73 is equal to or exceeds W. This study, which analyzed 439 PD patients at their first clearance study, used the Watson formulas estimating V to identify patients with VWatson/0.73 ≥ W and compared their nutritional indices with those of PD patients with VWatson/0.73 < W. The study identified at the first clearance study two male patients with VWatson/0.73 ≥ W among 439 patients on PD. Compared to 260 other male patients on PD, the two subjects with advanced wasting had exceptionally low body mass index and serum albumin concentration. The first of the two subjects also had very low values for serum creatinine concentration and total (in urine and spent peritoneal dialysate) creatinine excretion rate while the second subject had an elevated serum creatinine concentration and high creatinine excretion rate due, most probably, to non-compliance with the PD prescription. Advanced wasting (zero BF) in PD patients, identified by the anthropometric formulas that estimate V, while rare, is associated with indices of poor somatic and visceral nutrition.

The patient started on peritoneal dialysis 6 months before he was hospitalized. Two days before hospitalization, he developed cough and sputum and he visited an outpatient clinic, where dextromethorphan was prescribed. After taking a total of 30 mg of dextromethorphan, the patient developed myoclonus, tremor, agitation, slurred speech, and diaphoresis, which continued after he stopped taking the prescribed medicine. He visited an emergency department and was hospitalized for examination and treatment of myoclonus. As the patient's dialysis schedule was adequate, these symptoms were likely not due to uremia. The blood concentration of dextromethorphan (2.68 ng/mL) 60 hours after the 30-mg dose was higher than expected, and the blood concentration of dextrorphan, a metabolite, was lower than expected. We suspected that myoclonus was due to dextromethorphan-related symptoms induced by CYP2D6, which primarily metabolizes dextromethorphan. We analyzed the CYP2D6 gene for polymorphisms and identified CYP2D6 (*)1/(*)10. The patient had been taking metoprolol 40 mg/day for 2 years. The blood concentration of metoprolol 6 hours after administration was 13 ng/mL, which suggests that it was metabolized normally. Metoprolol has another metabolic pathway, via CYP2C19, and this may have led to its lack of accumulation. Moreover, metoprolol may have bound to active CYP2D6. Thus, affinity for CYP2D6, protein-binding rate, and lipid solubility may influence these drug interactions. Total scores for the Adverse Drug Reaction (ADR) probability scale and the Drug Interaction Probability Scale (DIPS) were 9 (highly probable) and 3 (possible), respectively. Myoclonus and other symptoms in this patient may have been caused by a prolonged high concentration of dextromethorphan due to CYP2D6 polymorphisms and drug

    The management of volume in patients with diabetes on peritoneal dialysis is affected by several factors, including the degree of residual renal function, peritoneal membrane small-solute transport, salt and water intake, blood sugar control, comorbidity, and nutritional status. It requires sequential evaluation of volume status and adjustment of the peritoneal dialysis prescription on the basis of assessments of membrane function and alterations in urine volume. Steps should be taken to preserve residual renal function for as long as possible. Ultimately, in patients who have become anuric and have developed ultrafiltration failure, timely transfer to hemodialysis may be necessary, requiring discussion and planning with the patient.

    Mycobacterium fortuitum group species is an atypical rapidly growing nontuberculous mycobacterium. It has been increasingly recognized as a potential pathogen mostly encountered in skin and soft tissue infections. Rarely, however, it has been associated with catheter-related infections, either central venous lines or peritoneal dialysis catheters. In this report we describe 2 patients maintained on continuous ambulatory peritoneal dialysis who developed Mycobacterium fortuitum peritonitis and a catheter tunnel abscess, respectively. Molecular biology identification of the isolates was performed in both cases. The literature is reviewed regarding all similar cases.

    Chronic systemic inflammation, a non traditional risk factor of cardiovascular diseases, is associated with increasing mortality in chronic kidney disease, especially peritoneal dialysis patients. Periodontitis is a potential treatable source of systemic inflammation in peritoneal dialysis patients. Clinical periodontal status was evaluated in 32 stable chronic peritoneal dialysis patients by plaque index and periodontal disease index. Hematologic, blood chemical, nutritional, and dialysis-related data as well as highly sensitive C-reactive protein were analyzed before and after periodontal treatment. At baseline, high sensitive C-reactive protein positively correlated with the clinical periodontal status (plaque index; r = 0.57, P < 0.01, periodontal disease index; r = 0.56, P < 0.01). After completion of periodontal therapy, clinical periodontal indexes were significantly lower and high sensitivity C-reactive protein significantly decreased from 2.93 to 2.21 mg/L. Moreover, blood urea nitrogen increased from 47.33 to 51.8 mg/dL, reflecting nutritional status improvement. Erythropoietin dosage requirement decreased from 8000 to 6000 units/week while hemoglobin level was stable. Periodontitis is an important source of chronic systemic inflammation in peritoneal dialysis patients. Treatment of periodontal diseases can improve systemic inflammation, nutritional status and erythropoietin responsiveness in peritoneal dialysis patients.

    The usefulness of icodextrin-containing peritoneal dialysis (PD) solution for the management of body fluid and blood pressure has been reported. However, icodextrin PD solution is a foreign solution in the body, and the possible induction of intraperitoneal inflammation has been reported. In this study, we investigated at 6-month intervals the influence of icodextrin solution on peritoneal permeability and inflammatory reactions in patients in whom glucose solution had been changed to icodextrin solution for the overnight dwell. We enrolled 9 anuric PD patients (5 men, 4 women) of mean age 58 +/- 5.9 years (range: 45.6-64.8 years) into the study. The patients' mean duration of PD was 61.9 +/- 42 months (range: 6.7-142.5 months). The cause of end-stage renal disease was chronic glomerulonephritis in all patients. For evaluation ofperitoneal permeability, we performed peritoneal equilibration tests (PETs) immediately after an overnight dwell and determined the dialysate-to-plasma ratios of creatinine (D/P Cr), beta2-microglobulin (D/P beta2m), albumin (D/P Alb), immunoglobulin G (D/P IgG), and alpha2-macroglobulin (D/P alpha2m). We also measured interleukin-6 (IL-6) and fibrinogen degradation products (FDPs) in overnight effluent as indices of inflammation and of the fibrinolysis-coagulation system. The evaluation was performed every 6 months for 24 months. The FDPs in effluent increased significantly at 6 months after the change to icodextrin solution, and IL-6 tended to increase. The D/P beta2m, D/P Alb, D/P IgG, and D/P alpha2m all significantly increased in the course of follow-up. In the PETs, the D/P Cr increased slightly, but the change was nonsignificant. At 30 months after the change to icodextrin solution, 1 patient was diagnosed as having a risk of encapsulating peritoneal sclerosis (pre-EPS). In this patient, rapid increases in IL-6, D/P Cr and macromolecular and small molecular D/P by PET were noted after the change to icodextrin solution. Steroids were

    The benefits of long-term peritoneal dialysis (PD) in patients with end-stage renal failure are short-lived due to structural and functional changes in the peritoneal membrane. In this report, we provide evidence for the in vitro and in vivo participation of the renin-angiotensin-aldosterone system (RAAS) in the signaling pathway leading to peritoneal fibrosis during PD. Exposure to high-glucose PD fluids (PDFs) increases damage and fibrosis markers in both isolated rat peritoneal mesothelial cells and in the peritoneum of rats after chronic dialysis. In both cases, the addition of the RAAS inhibitor aliskiren markedly improved damage and fibrosis markers, and prevented functional modifications in the peritoneal transport, as measured by the peritoneal equilibrium test. These data suggest that inhibition of the RAAS may be a novel way to improve the efficacy of PD by preventing inflammation and fibrosis following peritoneal exposure to high-glucose PDFs.

    Terminal-stage patients on peritoneal dialysis (PD) are often transferred to haemodialysis as they are unable to perform the dialysis technique themselves since their functional capacities are reduced. We present our experience with five patients on PD with a shortterm life-threatening condition, whose treatment was shared by primary care units and who were treated with a PD modality adapted to their circumstances, which we call Palliative Peritoneal Dialysis.

    In the Renal Unit of the Molinette Hospital of Turin, peritoneal dialysis (PD) was introduced in the mid 1960s to treat patients suffering from acute renal failure. The peritoneal catheter, which was then a stiff catheter, was inserted by a surgeon at each dialysis session. Between 1966 and 1970 there were a series of improvements, such as the first cycler for intermittent PD, fast-shift DP, and a homemade machine for automatic PD. During the early 1970s, a new type of stiff peritoneal catheter was introduced, which was used also for patients suffering from chronic renal failure. Towards the end of the 1970s the soft Tenckhoff peritoneal catheter started to be used, as well as continuous ambulatory peritoneal dialysis (CAPD), which made it possible to treat a large number of patients at home. The 1980s brought a new surgical technique for the insertion of the catheter, and in the 1990s new peritoneal catheters were introduced which reduced the number of early and late complications. Around the turn of the century, the PD service was reorganized and improved, with dedicated personnel and facilities. Moreover, automated PD was introduced and the treatment of peritonitis was standardized according to international guidelines.

    Interleukin-6 (IL-6) was determined in serum and peritoneal dialysis effluent (PDE) of patients on chronic ambulatory peritoneal dialysis (CAPD) by a biological assay measuring the proliferation of the IL-6-dependent 7TD1 cell line. Six patients free of peritonitis displayed low but significant levels of IL-6 (mean +/- 42 pg/ml) in PDE, while IL-6 was undetectable in serum. In 6 patients with staphylococcal peritonitis, a tremendous increase in PDE levels of IL-6 was noted (range: 5,832-37,491 pg/ml), while serum IL-6 remained either undetectable or on a low level except in one case. After 5 days of antibiotic treatment, IL-6 levels in PDE returned to basal values. We conclude that CAPD results in an intraperitoneal secretion of IL-6 which is markedly but transiently increased during peritonitis episodes.

    Catheter-related infections result in high patient morbidity, the need for temporary haemodialysis, and high costs. These infections are the main cause of limited technique survival in peritoneal dialysis. We introduced a protocol for the simultaneous peritoneoscopic insertion and removal of peritoneal catheters in patients with catheter-related infections. Peritoneal dialysis was continued the day after surgery using low-volume dwells and a dry abdomen during the daytime. The dialysate leukocyte count had to be below 100/mm3 before exchanging catheters, which was performed under antibiotic therapy based on culture sensitivity. The old catheter was removed after the new catheter had been inserted in the opposite abdominal region. CAPD patients were switched to APD for 1 week, which made prolonged hospitalization necessary. Simultaneous catheter insertion and removal was performed 25 times in 22 patients on CCPD and 15 times in 14 patients on CAPD. In CCPD patients, peritoneal dialysis was restarted after 1.0+/-0.1 days in 24 cases. One patient had sufficient residual renal function and discontinued CCPD until day 10. In 10 CAPD patients (11 procedures) APD was started 1.3+/-0.2 days after the procedure with CAPD beginning 7.1+/-0.6 days thereafter. Three CAPD patients preferred haemodialysis and restarted CAPD 10.0+/-2.1 days after surgery. One patient continued CAPD the day after surgery. In addition to minor complications (e.g. position-dependent outflow problems), dialysate leakage occurred in two patients. Two patients developed peritonitis within the first 30 days after surgery, one of which was procedure related. One patient had severe lower gastrointestinal bleeding 2 weeks after the procedure, which was not related to the catheter replacement. Ultimately, in 38 of 40 procedures the patients could successfully continue peritoneal dialysis. We conclude that simultaneous insertion and removal of a peritoneal dialysis catheter without interruption of peritoneal

    The number of patients with end-stage renal disease requiring dialysis has increased markedly over the last decade and continues to grow at an alarming rate in the United States. Of the currently available dialysis options for end-stage renal disease (hemodialysis and peritoneal dialysis), peritoneal dialysis (PD) is underutilized in the United States for nonmedical reasons. In fact, PD is the less expensive dialysis modality and may provide a survival advantage over hemodialysis in first 2 to 4 years of treatment, but that advantage is not as robust with increasing age and with the presence of diabetes. Moreover, the initial survival advantage is lost in long-term PD, mainly owing to changes in the peritoneal membrane from the use of conventional bio-incompatible PD solutions. Current data suggest that not many patients continue on PD beyond 10 years. The recent development of a more biocompatible PD solution should help to preserve membrane function, promote ultrafiltration, improve nutritional status, and, it is hoped, prolong the survival advantage of PD. Identification of molecular mechanisms involved in cellular responses leading to peritoneal fibrosis and angiogenesis evokes new therapeutic strategies that might protect the peritoneal membrane against the consequences of long-term PD.

    Although there have been many advancements in the treatment of patients with chronic kidney disease (CKD) over the last 50 years, in terms of reducing cardiovascular risk, mortality remains unacceptably high, particularly for those patients who progress to stage 5 CKD and initiate dialysis (CKD5d). As mortality risk increases exponentially with progressive CKD stage, the question arises as to whether preservation of residual renal function once dialysis has been initiated can reduce mortality risk. Observational studies to date have reported an association between even small amounts of residual renal function and improved patient survival and quality of life. Dialysis therapies predominantly provide clearance for small water-soluble solutes, volume and acid-base control, but cannot reproduce the metabolic functions of the kidney. As such, protein-bound solutes, advanced glycosylation end-products, middle molecules and other azotaemic toxins accumulate over time in the anuric CKD5d patient. Apart from avoiding potential nephrotoxic insults, observational and interventional trials have suggested that a number of interventions and treatments may potentially reduce the progression of earlier stages of CKD, including targeted blood pressure control, reducing proteinuria and dietary intervention using combinations of protein restriction with keto acid supplementation. However, many interventions which have been proven to be effective in the general population have not been equally effective in the CKD5d patient, and so the question arises as to whether these treatment options are equally applicable to CKD5d patients. As strategies to help preserve residual renal function in CKD5d patients are not well established, we have reviewed the evidence for preserving or losing residual renal function in peritoneal dialysis patients, as urine collections are routinely collected, whereas few centres regularly collect urine from haemodialysis patients, and haemodialysis dialysis

    Volume control is critical for peritoneal dialysis. Although peritoneal equilibration test (PET) has been used to clarify the peritoneal membrane characteristics, it is not able to adequately predict peritoneal fluid removal and optimize appropriately the dwell time. In the present study, we applied computer simulation and performed a more detailed evaluation of the fluid kinetics in patients with different ultrafiltration (UF) capacity. Patients who used three to four exchanges of 2.27% glucose dialysate per day (poor UF capacity group), and patients who used three to four exchanges of 1.36% glucose dialysate per day (good UF capacity group) to achieve adequate amount of peritoneal fluid removal were included in the present analysis. All included patients were asked to record appropriately their dialysis exchanges for the assessment of their peritoneal fluid transport characteristics. Seventeen continuous ambulatory peritoneal dialysis patients were selected in the present study, nine in poor UF capacity group and eight in good UF capacity group. Patients in poor UF capacity group had significantly higher daily glucose exposure, higher dialysate-to-plasma ratio of creatinine (D/P creatinine) values, and higher peritoneal fluid absorption rate, K(e), as compared to patients with good UF capacity. Our results suggest that patients with poor UF capacity have significant higher peritoneal small solute transport rate, and more importantly, higher peritoneal fluid absorption rate as compared to patients with good UF capacity.

    ♦ Background: The clinical courses and long-term outcomes of viridans streptococcus (VS) peritoneal dialysis (PD) peritonitis remain unclear. ♦ Methods: We conducted a retrospective analysis of all PD patients in a single center with gram-positive cocci (GPC) peritonitis between 2005 and 2011, and divided them into 3 groups: VS, other streptococci and other GPC (apart from VS). Clinical characteristics and outcomes of the VS group were compared with the other streptococci and other GPC groups, with prognostic factors determined. ♦ Results: A total of 140 patients with 168 episodes of GPC peritonitis (44% of all peritonitis) were identified over 7 years. Among these, 18 patients (13%) developed VS peritonitis, while 14 patients (10%) developed other streptococcal peritonitis. Patients with VS peritonitis had a high cure rate by antibiotic alone (94%), despite a high polymicrobial yield frequency (28%). We found that VS peritonitis carried a lower risk of Tenckhoff catheter removal and relapsing episodes than other GPC peritonitis (6% vs 11%), and a lower mortality than other streptococci peritonitis (0% vs 7%). However, after the index peritonitis episodes, VS, other streptococci, and other GPC group had a significantly increased peritonitis incidence compared with the period before the index peritonitis (all p < 0.01). Patients with VS peritonitis had a significantly higher incidence of refractory peritonitis compared with other streptococci or other GPC peritonitis in the long term (both p < 0.01). ♦ Conclusions: VS poses a higher risk of subsequent refractory peritonitis after the index episode as compared with other streptococcal or GPC peritonitis. It might be prudent to monitor the technique of these patients with VS peritonitis closely to avoid further peritonitis episodes. PMID:24497584

    Newborns with inborn errors of metabolism often present with hyperammonaemic coma, requiring prompt diagnosis and specific medical therapy, nutritional support and efficient toxin removal. Little information regarding the efficacy and safety of continuous venovenous haemodialysis (CVVHD) as an option for extracorporal ammonia detoxification in children is available. Twenty-one patients with hyperammonaemia [19 neonates (mean age 4.1 +/- 2.4 days) and two children 1 and 7 years of age, respectively] were admitted to our hospital for dialysis between 1996 and 2008. Seventeen children (15 neonates), received CVVHD. Four neonates received continuous peritoneal dialysis (CPD). All started medical treatment with sodium benzoate, l-arginine hydrochloride and carnitine as well as protein-restricted parenteral diets with high caloric intake before dialysis. Plasma ammonia levels (range 464-7267 microg/dl before dialysis and 27-3317 microg/dl after dialysis) were significantly reduced by 50% within 4.7 +/- 2.5 h with CVVHD compared with 13.5 +/- 6.2 h with CPD (P < 0.0001). Plasma ammonia levels <200 microg/dl critical range were achieved within 22.4 +/- 18.1 h in CVVHD patients compared with 35.0 +/- 24.1 h with CPD. Depending on the weight and blood pressure stability of the patients, mean blood flow velocities of 9.8 +/- 3.4 ml/kg/min and mean dialysate flow rates of 3925 +/- 2398 ml/min/1.73 m(2) were employed. Blood and dialysate flows significantly correlated with ammonia clearance and decay of ammonia in vivo. Because of the severe underlying disease, 18% of CVVHD patients died compared with 50% undergoing CPD. In total, 82% of CVVHD patients survived the first 6 months after dialysis. Among these, 43% were without sequelae, 43% developed moderate mental retardation, and two (14%) developed severe mental retardation. CVVHD effectively and quickly eliminates plasma ammonia.

    Little published information is available about access failure in children undergoing chronic peritoneal dialysis. Our objectives were to evaluate frequency, risk factors, interventions, and outcome of peritoneal dialysis access revision. Data were derived from 824 incident and 1629 prevalent patients from 105 pediatric nephrology centers enrolled in the International Pediatric Peritoneal Dialysis Network Registry between 2007 and 2015. In total, 452 access revisions were recorded in 321 (13%) of 2453 patients over 3134 patient-years of follow-up, resulting in an overall access revision rate of 0.14 per treatment year. Among 824 incident patients, 186 (22.6%) underwent 188 access revisions over 1066 patient-years, yielding an access revision rate of 0.17 per treatment year; 83% of access revisions in incident patients were reported within the first year of peritoneal dialysis treatment. Catheter survival rates in incident patients were 84%, 80%, 77%, and 73% at 12, 24, 36, and 48 months, respectively. By multivariate logistic regression analysis, risk of access revision was associated with younger age (odds ratio, 0.93; 95% confidence interval, 0.92 to 0.95; P<0.001), diagnosis of congenital anomalies of the kidney and urinary tract (odds ratio, 1.28; 95% confidence interval, 1.03 to 1.59; P=0.02), coexisting ostomies (odds ratio, 1.42; 95% confidence interval, 1.07 to 1.87; P=0.01), presence of swan neck tunnel with curled intraperitoneal portion (odds ratio, 1.30; 95% confidence interval, 1.04 to 1.63; P=0.02), and high gross national income (odds ratio, 1.10; 95% confidence interval, 1.02 to 1.19; P=0.01). Main reasons for access revisions included mechanical malfunction (60%), peritonitis (16%), exit site infection (12%), and leakage (6%). Need for access revision increased the risk of peritoneal dialysis technique failure or death (hazard ratio, 1.35; 95% confidence interval, 1.10 to 1.65; P=0.003). Access dysfunction due to mechanical causes doubled the risk

Fifty of these incremental PD patients were using automated PD (APD) with either no day dwell (68%) or less than 7 days a week treatment (12%) or both (20%). Patient survival in our PD unit was not different from that reported in Canada as a whole. Peritonitis rates were better than internationally recommended standards. This is an observational study with no randomized control group. Incremental PD is feasible in a contemporary PD population treated mainly with APD. Almost half of the patients were able to achieve clearance targets while receiving less onerous and less costly low clearance prescriptions. We suggest that incremental PD should be widely used as a cost-effective strategy in PD.

    Mycobacterium fortuitum peritonitis is a rare complication in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). A 47-year-old patient was admitted to our tertiary hospital because of culture-negative peritonitis with persisting signs of infection despite adequate empirical antibiotic treatment. Although M. fortuitum was detected and the antibiotic regime subsequently amended, catheter removal was inevitable and the dialysis modality converted to hemodialysis (HD). After long-term antibiotic treatment and an additional latency of 4 months without signs of residual infection, reinitiation of CAPD was planned. Explorative laparoscopy prior to catheter reinsertion revealed multiple adhesions within the peritoneal cavity, preventing adequate catheter function. The clinical course of M. fortuitum peritonitis, the need for catheter removal and the description of peritoneal changes are discussed regarding to recent literature.

    The highly concentrated lactate in peritoneal dialysis fluid (PDF) has been considered to contribute to peritoneal failure in patients undergoing PD. A new PDF containing a lower lactate concentration, physiological bicarbonate concentration, and neutral pH (bicarbonate/lactate-buffered neutral PDF) was recently developed. We compared the clinical effects of this bicarbonate/lactate-buffered neutral PDF and a lactate-buffered neutral PDF. Patients undergoing PD were changed from a lactate-buffered neutral PDF to a bicarbonate/lactate-buffered neutral PDF. We then investigated the changes in peritoneal functions as estimated by a peritoneal equilibration test (PET) and the following surrogate markers of peritoneal membrane failure in the drained dialysate: fibrin degradation products (FDP), vascular endothelial growth factor (VEGF), cancer antigen 125 (CA125), interleukin-6 (IL-6), and transforming growth factor beta 1 (TGF-β1). Fourteen patients undergoing PD were enrolled. The PET results were not different before and after use of the bicarbonate/lactate-buffered neutral PDF. The FDP concentration significantly decreased from 15.60 ± 13.90 to 6.04 ± 3.49 μg/mL (p = 0.02) and the VEGF concentration significantly decreased from 37.83 ± 15.82 to 27.70 ± 3.80 pg/mL (p = 0.02), while the CA125 and IL-6 concentrations remained unchanged before and after use of the bicarbonate/lactate-buffered neutral PDF. TGF-β1 was not detected in most patients. The bicarbonate/lactate-buffered neutral PDF decreased the FDP and VEGF concentrations in the drained dialysate. These results suggest that the decreased lactate level achieved by administration of bicarbonate with a neutral pH in PDF may contribute to decreased peritoneal membrane failure in patients undergoing PD.

    Sphingomonas species are ubiquitous gram-negative, aerobic bacteria frequently found in aquatic environments such as drinking water and very seldom in hemodialysis fluids or supposedly sterile drug solutions. Human infections with the gram-negative Sphingomonas species are rare and peritonitis with these organisms even rarer. Here we report a case of polymicrobial peritonitis due to Sphingomonas koreensis and Escherichia coli in a patient undergoing peritoneal dialysis (PD).

    Peritoneal dialysis (PD) frequently leads to body weight gain, which appears to be a potential cause of the chronic inflammation frequently present in these patients. The consequences of this inflammation are impaired nutritional status, accelerated atherosclerosis, and increased mortality. To assess the association between inflammation and body fat in female patients treated with PD. Nineteen female patients on PD for at least 6 months with no infectious complications or malignant or acute inflammatory diseases. Nutritional status was determined by measuring weight, height, body mass index (BMI), waist (WC), and mid-arm circumferences (MAC), mid-arm muscle area, and tricipital fold (TCF). Bioelectrical impedance (BIA) was used to determine body composition. Biochemical evaluation included the determination of serum albumin, urea, creatinine, and C-reactive protein (CRP). The glucose absorbed from the dialysis solution was quantitated. According to BMI, two patients were classified as malnourished and ten as overweight/obese. Sixteen individuals had high WC measurements and 12 had excess body fat (BF) as measured by BIA. High CRP levels were observed in 12 patients, who had higher WC, MAC, BMI, TCF, and BF measurements compared to non-inflamed patients. Positive associations were detected between CRP and BMI, MAC, WC, and TCF. Associations between BF and CRP suggest that adiposity may be a potent exacerbating factor of inflammation in this population, especially visceral fat. Thus, obesity may be considered to be one more factor responsible for the early atherosclerosis and high cardiovascular mortality observed in these patients.

    The pharmacokinetics of cefepime were studied in 10 male patients receiving continuous ambulatory peritoneal dialysis therapy. Five patients received a single 1,000-mg dose and the other five received a single 2,000-mg dose; all doses were given as 30-min intravenous infusions. Serial plasma, urine, and peritoneal dialysate samples were collected; and the concentrations of cefepime in these fluids were measured over 72 h by using a high-performance liquid chromatographic assay with UV detection. Pharmacokinetic parameters were calculated by noncompartmental methods. The peak concentrations in plasma and the areas under the plasma concentration-versus-time curve for the 2,000-mg dose group were twice as high as those observed for the 1,000-mg dose group. The elimination half-life of cefepime was about 18 h and was independent of the dose. The steady-state volume of distribution was about 22 liters, and values for the 1,000- and 2,000-mg doses were not significantly different. The values for total body clearance and peritoneal dialysis clearance were about 15 and 4 ml/min, respectively. No dose dependency was observed for the clearance estimates. Over the 72-h sampling period, about 26% of the dose was excreted intact into the peritoneal dialysis fluid. For 48 h postdose, mean concentrations of cefepime in dialysate at the end of each dialysis interval exceeded the reported MICs for 90% of the isolates (MIC90s) for bacteria which commonly cause peritonitis resulting from continuous peritoneal dialysis. A parenteral dose of 1,000 or 2,000 mg of cefepime every 48 h would maintain the antibiotic levels in plasma and peritoneal fluid above the MIC90s for the most susceptible bacteria for the treatment of systemic and intraperitoneal infections [corrected].

    Management of the pregnant patient on peritoneal dialysis (PD) is potentially challenging because uterine enlargement may negatively affect catheter function and prescribed dwell volumes. Additional reports of the management of these patients are needed. Here, we describe a near-full-term delivery in a 27-year-old woman who had been on dialysis for 7 years. Peritoneal dialysis was continued during the entire pregnancy. In the third trimester, a higher delivered automated PD volume allowed for adequate clearance and control of volume status. A decision to hospitalize the patient to limit activity and facilitate the delivery of increased dialysate is believed to have contributed to the successful outcome for mother and infant. Our report discusses the management of this patient and reviews published dialysis prescriptions used during the third trimester of pregnancy in patients treated with PD.

    The survival of patients with end-stage renal disease (ESRD) resulting from diabetes continues to improve, but the survival rate among diabetic ESRD patients remains the lowest among all primary diagnoses probably because of the higher prevalence of cardiovascular comorbidity associated with diabetes. Diabetes, age, and comorbidity all significantly modify the effect of treatment modality on patient survival. As compared with hemodialysis (HD), peritoneal dialysis (PD) offers an equal or lower risk of death across all subgroups during the first 1-2 years of dialysis. The association of PD with better outcomes than are seen with HD is probably a result of a lower prevalence of infections and congestive heart failure and better preservation of residual renal function (RRF) in PD patients. Use of angiotensin converting-enzyme inhibitor (ACEI) or angiotensin II receptor blocker (ARB) helps to preserve RRF in ESRD patients and to maintain peritoneal membrane integrity longer in PD patients. Antioxidants can also support preservation of peritoneal membrane function. Peritoneal dialysis should be the initial modality of dialysis in all ESRD patients. Older patients (age > or = 45 years) with diabetes and patients without diabetes may switch to HD or receive a kidney graft in 1-2 years' time; younger patients (age < 45 years) with diabetes may stay on PD longer. Use of ACEI and ARB or antioxidants can help to maintain peritoneal membrane function longer.

    Peritoneal dialysis is a fully-contrasted alternative for the treatment of end-stage renal disease although it is not exempt of complications. Peritonitis and exit-site infections are among the most frequent complications found. Pleural effusion secondary to pleuroperitoneal communication (PPC) is a serious and uncommon complication in these patients. We present the case of a 50-year old man diagnosed of end-stage renal disease undergoing treatment with peritoneal dialysis who presented progressive dyspnea and right pleural effusion. The peritoneal scintigraphy with (99m)Tc-MAA makes it possible to confirm communication of intraperitoneal dialysis fluid to the pleural cavity. Copyright 2009 Elsevier España, S.L. y SEMNIM.

  3. Portable or wearable peritoneal devices--the next step forward for peritoneal dialysis?

    PubMed

    Davenport, Andrew

    2012-01-01

    Peritoneal dialysis can be considered a "wearable" dialysis therapy. However, patients typically require 3 or 4 daily exchanges, each taking 20-40 minutes and potentially increasing the risk of infection by repeated disconnection and reconnection. Although peritoneal dialysis cyclers allow patients to be "free" from their machine for 13-15 hours, they similarly need a supply of fresh dialysate. Several groups have therefore explored the possibility of trying to minimize dialysate exchanges by recycling dialysate. However, that approach introduces not only a series of challenges, including regeneration of the spent dialysate, maintenance of acid-base and electrolyte balance and adequate ultrafiltration, but also new hurdles to be overcome, including monitoring the sorbents to determine when capacity is exceeded. The proposed Vicenza Wearable Artificial Kidney system consists of a continuous-flow peritoneal dialysis system that combines sorbents in series and urease to regenerate dialysate during the day, and a 7.5% icodextrin exchange overnight.

    ♦ Background: Peritonitis rate has been reported to be associated with technique failure and overall mortality in previous literatures. However, information on the impact of the timing of the first peritonitis episode on continuous ambulatory peritoneal dialysis (CAPD) patients is sparse. The aim of this research is to study the influence of time to first peritonitis on clinical outcomes, including technique failure, patient mortality and dropout from peritoneal dialysis (PD). ♦ Methods: A retrospective observational cohort study was conducted over 10 years at a single PD unit in Taiwan. A total of 124 patients on CAPD with at least one peritonitis episode comprised the study subjects, which were dichotomized by the median of time to first peritonitis into either early peritonitis patients or late peritonitis patients. Cox proportional hazard model was used to analyze the correlation of the timing of first peritonitis with clinical outcomes. ♦ Results: Early peritonitis patients were older, more diabetic and had lower serum levels of creatinine than the late peritonitis patients. Early peritonitis patients were associated with worse technique survival, patient survival and stay on PD than late peritonitis patients, as indicated by Kaplan-Meier analysis (log-rank test, p = 0.04, p < 0.001, p < 0.001, respectively). In the multivariate Cox regression model, early peritonitis was still a significant predictor for technique failure (hazard ratio (HR), 0.54; 95% confidence interval (CI), 0.30 - 0.98), patient mortality (HR, 0.34; 95% CI, 0.13 - 0.92) and dropout from PD (HR, 0.50; 95% CI, 0.30 - 0.82). In continuous analyses, a 1-month increase in the time to the first peritonitis episode was associated with a 2% decreased risk of technique failure (HR, 0.98; 95% CI, 0.97 - 0.99), a 3% decreased risk of patient mortality (HR, 0.97; 95% CI, 0.95 - 0.99), and a 2% decreased risk of dropout from PD (HR, 98%; 95% CI, 0.97 - 0.99).

    Encapsulating peritoneal sclerosis is a pathological entity mainly associated with peritoneal dialysis (PD). The clinical syndrome is characterized by various degrees of intestinal obstruction due to thickening, sclerosis and calcification of peritoneum resulting in the encapsulation and cocooning of the bowel. It is a rare but potentially devastating complication associated with a considerable morbidity and mortality. Cases of encapsulating peritoneal sclerosis (EPS), diagnosed in the Surgical Clinic of "Cantacuzino" Hospital, between 2007 and 2014 were retrospectively reviewed. During this interval, 432 surgical interventions related to peritoneal dialysis were performed: 306 peritoneal access interventions and 124 complications, of which 15 patients with EPS. In all but two cases, the EPS diagnostic was established at the time of the surgical intervention addressed to other complication or pathology. Moreover, in 2 of the 15 patients the diagnostic was established approximately 5 months after PD was discontinued, and, in one of these patients at the time of the extraction of the dialysis catheter. 12 of 15 patients were diabetic. Most patients had a history of multiple peritonitis episodes. All the patients required the passing from peritoneal dialysis to hemodialysis. There were 4 deaths (26,6%) of which one was around two months from the diagnosis. The timely diagnosis of the condition and the appropriate phase-specific treatment is of utmost importance in EPS. In advanced stages, the surgical intervention performed by a well-trained team could achieve good long-term results.

    Delayed graft function (DGF) in kidney transplantation affects adverse outcomes. It remains unclear whether the post-transplant dialysis modality alters perioperative or long-term graft outcomes. We performed a retrospective observational quality initiative at two Canadian renal transplant centers, in which DGF occurred in the recipient, necessitating one of peritoneal dialysis (PD) or hemodialysis (HD). There was no difference in baseline factors between patients with post-transplant PD (n = 14) or HD (n = 63). The use of PD was associated with an increased risk of wound infection/leakage (PD 5/14 vs. HD 6/63, p = 0.024), shorter length of hospitalization (13.7 vs. 18.7 d, p = 0.009) and time requiring dialysis post-operatively (6.5 vs 11.0 d, p = 0.043). There were no differences in readmission to hospital within 6 months (4/14 vs. 23/63, p = 0.759), graft loss (0/14 vs. 2/63, p = 1.000) or acute rejection episodes (1/14 vs. 4/63, p = 1.000) at one yr, and GFR did not differ between the PD or HD groups at 30 d (35.7 vs. 33.8 mL/min/m(2), p = 0.731), six months (46.9 vs. 45.5 mL/min/m(2), p = 0.835) or one yr (46.6 vs. 44.5 mL/min/m(2), p = 0.746). Further research is needed to determine which transplant patients are most appropriate to undergo PD catheter removal at the time of transplantation. © 2013 John Wiley & Sons A/S.

    Abstract Peritonitis remains a major complication of peritoneal dialysis (PD). A high peritonitis rate (HPR) affects continuous ambulatory peritoneal dialysis (CAPD) patients’ technique survival and mortality. Predictors and outcomes of HPR, rather than the first peritonitis episode, were rarely studied in the Chinese population. In this study, we examined the risk factors associated with HPR and its effects on clinical outcomes in CAPD patients. This is a single center, retrospective, observational cohort study. A total of 294 patients who developing at least 1 episode of peritonitis were followed up from March 1st, 2002, to July 31, 2014, in our PD center. Multivariate logistic regression was used to determine the factors associated with HPR, and the Cox proportional hazard model was conducted to assess the effects of HPR on clinical outcomes. During the study period of 2917.5 patient-years, 489 episodes of peritonitis were recorded, and the total peritonitis rate was 0.168 episodes per patient-year. The multivariate analysis showed that factors associated with HPR include a quick occurrence of peritonitis after CAPD initiation (shorter than 12 months), and a low serum albumin level at the start of CAPD. In the Cox proportional hazard model, HPR was a significant predictor of technique failure. There were no differences between HPR and low peritonitis rate (LPR) group for all-cause mortality. However, when the peritonitis rate was considered as a continuous variable, a positive correlation was observed between the peritonitis rate and mortality. We found the quick peritonitis occurrence after CAPD and the low serum albumin level before CAPD were strongly associated with an HPR. Also, our results verified that HPR was positively correlated with technique failure. More importantly, the increase in the peritonitis rate suggested a higher risk of all-cause mortality. These results may help to identify and target patients who are at higher risk of HPR at the start

    Automated peritoneal dialysis (APD) becomes the first option for peritoneal dialysis, nowadays overtaking continuous ambulatory peritoneal dialysis (CAPD) in many countries. The comparison of peritoneal membrane alteration in CAPD and APD is inconclusive. The authors therefore compared the peritoneal membrane changes in patients undergoing CAPD and APD. In naive end stage renal disease patients, the choice of PD modes (CAPD or APD) was dependent on the patient's decision. Thirty-six CAPD and 25APD patients with a total of 287 patient-months were compared. The peritoneal mass parameter, exfoliated mesothelial cell (MTC) and dialysate CA-125, as well as modified peritoneal equilibrium test (mPET) with 4.25% dextrose solution was simultaneously evaluated at 1 and 6 month follow-up. Although the peritoneal function (as measured by D/P creatinine, D/D0 glucose, sodium dipping, and dialysate protein loss), adequacy, serum albumin, nutritional status, and residual renal function showed no significant differences between groups at 1 and 6 months, CA-125 but not MTC was higher in APD compared with CAPD at the first month of PD beginning. Due to the single time-point measurement limitation, the authors compared the peritoneal mass parameter differences between 1 and 6 month. During 6-month follow-up, CA-125 decreased 30 +/- 5% vs. 7 +/- 5% and MTC decreased 5 +/- 12% vs. 40 +/- 11% in APD and CAPD, respectively. The higher CA-125 reduction in APD and greater changes of MTC in CAPD suggested that there was less viable mesothelial cell in APD compared with CAPD. The authors observed that both APD and CAPD damaged peritoneum. However, there might be higher peritoneal injury in APD patients. The proper randomization study in longer follow-up period is mandatory to confirm this observation.

    In patients undergoing peritoneal dialysis (PD), PD-related infection is a major cause of PD failure and hospital admission. Good air quality is required when dialysate exchange or exit site wound care is performed. To our knowledge, investigation of air pollution as a factor for PD-related infection in patients undergoing dialysis is limited. This study aimed to assess the effect of environmental particulate matter (PM) and other important risk factors on 1-year PD-related infection in patients undergoing PD.A total of 175 patients undergoing PD were recruited in this 1-year retrospective observational study. Differences in environmental PMs (PM10 and PM2.5) were analyzed with respect to the patients' living areas. The patients undergoing PD were categorized into 2 groups according to PM2.5 exposure: high (n = 61) and low (n = 114). Demographic, hematological, nutritional, inflammatory, biochemical, and dialysis-related data were analyzed. Multivariate binary logistic and multivariate Cox regression analyses were used to analyze 1-year PD-related infection.A total of 175 patients undergoing PD (50 men and 125 women) were enrolled. Thirty-five patients had PD-related infection within 1 year. Multivariate Cox regression analysis showed that high environmental PM2.5 exposure (hazard ratio (HR): 2.0, 95% confidence interval [CI] [1.03-3.91]; P = .04) and female sex (HR: 2.77, 95% CI [1.07-7.19]; P = .03) were risk factors for 1-year PD-related infection.Patients undergoing PD with high environmental PM2.5 exposure had a higher 1-year PD-related infection rate than that in those with low exposure. Therefore, air pollution may be associated with PD-related infection in such patients.

    AIM: To investigate the effect of gastric acid suppressants and prokinetics on peritonitis development in peritoneal dialysis (PD) patients. METHODS: This was a single-center, retrospective study. The medical records of 398 PD patients were collected from January 2000 to September 2012 and analyzed to compare patients with at least one episode of peritonitis (peritonitis group, group A) to patients who never had peritonitis (no peritonitis group, group B). All peritonitis episodes were analyzed to compare peritonitis caused by enteric organisms and peritonitis caused by non-enteric organisms. RESULTS: Among the 120 patients who met the inclusion criteria, 61 patients had at least one episode of peritonitis and 59 patients never experienced peritonitis. Twenty-four of 61 patients (39.3%) in group A and 15 of 59 patients (25.4%) in group B used gastric acid suppressants. Only the use of H2-blocker (H2B) was associated with an increased risk of PD-related peritonitis; the use of proton pump inhibitors, other antacids, and prokinetics was not found to be a significant risk factor for PD-related peritonitis. A total of 81 episodes of peritonitis were divided into enteric peritonitis (EP) or non-enteric peritonitis, depending on the causative organism, and gastric acid suppressants and prokinetics did not increase the risk of EP in PD patients. CONCLUSION: The use of H2B showed a trend for an increased risk of overall PD-related peritonitis, although further studies are required to clarify the effects of drugs on PD-related peritonitis.

    The relation of various demographic, clinical and biochemical parameters of peritoneal dialysis patients with peritonitis and other infections was evaluated. The age, gender, peritoneal dialysis (PD) period, educational status, peritonitis, exit site score, serum albumin, C-reactive protein (CRP), and triglyceride levels at the beginning and the last visit were recorded. Mean age of 32 patients was 45.1 years; PD period was 13.1 months. Albumin level was inversely proportional to the frequency of peritonitis. Patients with peritonitis had albumin levels that were lower at the last visit, and were independent of the CRP values at the start of PD and during follow-up. Significant correlation was detected between females and exit site scores. There was significant correlation between educational status and peritonitis. Albumin level at first visit was a factor that reduced the likelihood of peritonitis, and low levels obtained during follow-up constituted a risk for peritonitis. It was also shown that peritonitis risk tended to decrease inversely with education level.

    The impact of peritoneal dialysis modality on patient survival and peritonitis rates is not fully understood, and no large-scale randomized clinical trial (RCT) is available. In the absence of a RCT, the use of an advanced matching procedure to reduce selection bias in large cohort studies may be the best approach. The aim of this study is to compare automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) according to peritonitis risk, technique failure and patient survival in a large nation-wide PD cohort. This is a prospective cohort study that included all incident PD patients with at least 90 days of PD recruited in the BRAZPD study. All patients who were treated exclusively with either APD or CAPD were matched for 15 different covariates using a propensity score calculated with the nearest neighbor method. Clinical outcomes analyzed were overall mortality, technique failure and time to first peritonitis. For all analysis we also adjusted the curves for the presence of competing risks with the Fine and Gray analysis. After the matching procedure, 2,890 patients were included in the analysis (1,445 in each group). Baseline characteristics were similar for all covariates including: age, diabetes, BMI, Center-experience, coronary artery disease, cancer, literacy, hypertension, race, previous HD, gender, pre-dialysis care, family income, peripheral artery disease and year of starting PD. Mortality rate was higher in CAPD patients (SHR1.44 CI95%1.21-1.71) compared to APD, but no difference was observed for technique failure (SHR0.83 CI95%0.69-1.02) nor for time till the first peritonitis episode (SHR0.96 CI95%0.93-1.11). In the first large PD cohort study with groups balanced for several covariates using propensity score matching, PD modality was not associated with differences in neither time to first peritonitis nor in technique failure. Nevertheless, patient survival was significantly better in APD patients.

    A 70-years of age, male patient with underlying type 2 diabetes mellitus, hypertension, dyslipidemia and ischemic heart disease had undergone continuous ambulatory peritoneal dialysis (CAPD)for 3 years without any episodes of peritonitis. He was diagnosed with necrotizing fasciitis and later developed peritonitis after receiving a laceration from an aquatic injury suffered during the flood disaster of 2011. The blood culture, necrotic tissue and the clear dialysate collected upon admission had shown Aeromonas sobria. The route of peritonitis may be from the hematogenous spread of A. sobria resulting in necrotizing fasciitis. A. sobria should be considered as the pathogen of peritonitis in PD patients who have history of wounds from contaminated water. We suggest that the PD patients who present with septicemia and did not meet the criteria for peritonitis, the initial dialysate effluent should be sent for culture. The benefit of this is to allow early recognition and treatment of peritonitis.

    Hydrothorax is a rare complication of continuous ambulatory peritoneal dialysis (CAPD) which can progress quickly to cause acute respiratory distress. We present a 76 year-old female with a past medical history significant for end-stage renal disease (ESRD) on daily home peritoneal dialysis for 2 years presented to the hospital from home with shortness of breath at rest and cough for 2 days prior to admission. She developed severe respiratory distress and had emergent pleurocentesis that released 3.8 L of pleural fluid. The analysis showed significantly high sugar indicative of hydrothorax from CAPD. She underwent thoracotomy with pleurodesis and switched to hemodialysis for 6 weeks before resuming CAPD. A high glucose concentration in the pleural fluid is pathognomonic for hydrothorax from dialysis fluid after rule out other possible causes of pleural effusion. Patients who are on CAPD presenting with marked pleural effusion should prompt clinicians to consider the differential diagnosis of pleuroperitoneal communications.

    Escherichia coli (E. coli) peritonitis is a frequent, serious complication of peritoneal dialysis (PD). The extended-spectrum β-lactamase (ESBL)-producing E. coli peritonitis is associated with poorer prognosis and its incidence has been on continuous increase during the last decades. However, the clinical course and outcomes of E. coli peritonitis remain largely unclear. All of the E. coli peritonitis episodes that occurred in our dialysis unit from 2006 to 2011 were reviewed. The polymicrobial episodes were excluded. In total, ninety episodes of monomicrobial E. coli peritonitis occurred in 68 individuals, corresponding to a rate of 0.027 episodes per patient-year. E. coli was the leading cause (59.2%) of monomicrobial gram-negative peritonitis. ESBL-producing strains accounted for 35.5% of E. coli peritonitis. The complete cure rate and treatment failure rate of E. coli peritonitis were 77.8% and 10.0% respectively. Patients with preceding peritonitis had a higher risk of ESBL production as compared to those without peritonitis history [odds ratio (OR): 5.286; 95% confidence interval (CI): 2.018 - 13.843; p = 0.001]. The risk of treatment failure was significantly increased when the patient had a baseline score of Charlson Comorbidity Index (CCI) above 3 (OR: 6.155; 95% CI: 1.198 - 31.612; p = 0.03), or had diabetes mellitus (OR: 8.457; 95% CI: 1.838 - 38.91; p = 0.006), or hypoalbuminemia (≤ 30g/l) on admission (OR: 13.714; 95% CI: 1.602 - 117.428; p = 0.01). Prolonging the treatment course from 2 to 3 weeks or more reduced the risk of relapse and repeat significantly (p < 0.05). E. coli peritonitis remains a common complication of PD. The clinical outcomes of E. coli peritonitis are relatively favorable despite the high ESBL rate. A history of peritonitis is associated with increased risk for ESBL development. The severity of baseline comorbidities, the presence of diabetes mellitus and hypoalbuminemia at admission are associated with poor outcomes

    ♦ BACKGROUND: Melioidosis, an infectious disease caused by Burkholderia pseudomallei, is endemic in Southeast Asia and Northern Australia. Although a wide range of clinical manifestations from this organism are known, peritonitis associated with peritoneal dialysis (PD) has rarely been reported. ♦ PATIENTS AND METHODS: Peritoneal dialysis patients from all regions in Thailand were eligible for the study if they had peritonitis and either peritoneal fluid or effluent culture positive for B. pseudomallei. Patient data obtained included baseline characteristics, laboratory investigations, treatments, and clinical outcomes. When possible, PD fluid and removed Tenckhoff (TK) catheters were submitted for analyses of minimal inhibitory concentration (MIC) and microbial biofilm, respectively. ♦ RESULTS: Twenty-six patients were identified who were positive for peritoneal B. pseudomallei infection. The recorded mean age was 50 ± 15 (24 - 75) years, and the majority (58%) were female. Most of the cases were farmers living in Northeastern and Northern Thailand. Almost half of the cases had diabetes. Infections were reported commonly during the monsoon season and winter. The clinical presentations of peritonitis were similar to the manifestations from other microorganisms. Nine patients (41%) died (7 from sepsis), 6 fully recovered, and 7 switched to permanent hemodialysis. The mortality was potentially associated with sepsis (p = 0.007), infection during the monsoon season (p = 0.017), high initial dialysate neutrophils (p = 0.045), and high hematocrit (p = 0.045). Although no antibiotic resistance to ceftazidime and carbapenems was detected, approximately 50% of patients died with this treatment. Microbial biofilms were identified on the luminal surface of 4 out of 5 TK catheters, but the removal of the catheter did not alter the outcomes. ♦ CONCLUSION: Peritoneal dialysis-related peritonitis due to melioidosis is uncommon but highly fatal.

    Faster peritoneal transport has been associated with an increased risk of therapy failure and patient mortality. However, faster transport can the result of many factors. Peritoneal protein clearance (PPC) has been proposed to distinguish faster peritoneal transport attributable to inflammatory conditions, as protein clearance reflects large-pore flow, which increases during inflammation. We followed a cohort of 300 peritoneal dialysis patients, and after adjustments for age and comorbidity, higher PPC was associated with increased risk of death (hazard ratio: 1.81; 95% confidence interval: 1.11 to 2.95), even after patients underwent transplantation or transferred to hemodialysis.

    Numerous factors related to the composition of peritoneal dialysis solutions (PDS) contribute to the pathogenesis of peritoneal fibrosis during continuous ambulatory peritoneal dialysis (CAPD). They include high osmolarity, low pH, and the presence of lactate, which may be responsible for stimulating the proliferation of peritoneal fibroblasts (PF) and for the toxicity on the peritoneal mesothelial cells (PMC). Similar effects could be hypothesized for the plasticizers released from the PDS bags, usually made of polyvinyl chloride (PVC), such as the acid esters of phthalic acid, particularly bis-(2-ethylhexyl) phthalate (BEHP). Recently, however, new BEHP-free bags (Clear-Flex, Bieffe, Italy) made of three layers (polyethylene, nylon, and polypropylene) have been introduced. The aim of this work is to evaluate in vitro the effects of samples of PDS contained in PVC bags (Bieffe) and in Clear-Flex bags on the proliferative capacity of peritoneal fibroblasts and peritoneal mesothelial cells, and the release of interferon gamma (IFN gamma), interleukin-1 (IL-1) and prostaglandin E2 (PGE2) from peritoneal T lymphocytes (PTLs) and macrophages (PM phi s). Results have shown that in the presence of PDS samples contained in PVC bags, the proliferative capacity of peritoneal fibroblasts was higher than in Clear-Flexbags. There was also an increased release of IFN-gamma and IL-1 from PTLs and PM phi s (cytokines that stimulate the collagen synthesis) and a decreased release of PGE2 (cytokines which inhibit the collagen synthesis). An inhibiting action on peritoneal mesothelial cells was also seen.(ABSTRACT TRUNCATED AT 250 WORDS)

    The clinical benefits of using “biocompatible” neutral pH solutions containing low levels of glucose degradation products for peritoneal dialysis compared with standard solutions are uncertain. In this multicenter, open-label, parallel-group, randomized controlled trial, we randomly assigned 185 incident adult peritoneal dialysis patients with residual renal function to use either biocompatible or conventional solution for 2 years. The primary outcome measure was slope of renal function decline. Secondary outcome measures comprised time to anuria, fluid volume status, peritonitis-free survival, technique survival, patient survival, and adverse events. We did not detect a statistically significant difference in the rate of decline of renal function between the two groups as measured by the slopes of GFR: −0.22 and −0.28 ml/min per 1.73 m2 per month (P=0.17) in the first year in the biocompatible and conventional groups, respectively, and, −0.09 and −0.10 ml/min per 1.73 m2 per month (P=0.9) in the second year. The biocompatible group exhibited significantly longer times to anuria (P=0.009) and to the first peritonitis episode (P=0.01). This group also had fewer patients develop peritonitis (30% versus 49%) and had lower rates of peritonitis (0.30 versus 0.49 episodes per year, P=0.01). In conclusion, this trial does not support a role for biocompatible fluid in slowing the rate of GFR decline, but it does suggest that biocompatible fluid may delay the onset of anuria and reduce the incidence of peritonitis compared with conventional fluid in peritoneal dialysis.

    Biofilms are commonly associated with an increased risk of patient infection. In peritoneal dialysis (PD), catheter associated infection, especially peritonitis, remains a clinically relevant problem. Although the presence of a biofilm is recognized in relapsing, repeat, and catheter-related peritonitis, it remains poorly characterized. In this review, an update on the role of biofilms in PD infections is presented. The emerging concept that host cells and tissue associated biofilms, in addition to the biofilms on the catheters themselves, contribute to the recalcitrance of infections is discussed. Furthermore, the evidence of biofilms on PD catheters, their developmental stages, and the possible influence of the PD environment are reviewed. The focus is given to ex vivo and in vitro studies that contribute to the elucidation of the interplay between host, microbial, and dialysis factors. The key issues that are still to be answered and the challenges to clinical practice are discussed.

    The management of volume in patients with diabetes on peritoneal dialysis is affected by several factors, including the degree of residual renal function, peritoneal membrane small-solute transport, salt and water intake, blood sugar control, comorbidity, and nutritional status. It requires sequential evaluation of volume status and adjustment of the peritoneal dialysis prescription on the basis of assessments of membrane function and alterations in urine volume. Steps should be taken to preserve residual renal function for as long as possible. Ultimately, in patients who have become anuric and have developed ultrafiltration failure, timely transfer to hemodialysis may be necessary, requiring discussion and planning with the patient.

    Currently, chronic kidney disease (CKD) is a global health problem. Considering the impaired immunity of CKD patients, the relevance of infection in peritoneal dialysis (PD), and the increased prevalence of parasites in CKD patients, protozoa colonization was evaluated in PD effluent from CKD patients undergoing PD. Overnight PD effluent was obtained from 49 asymptomatic stable PD patients. Protozoa analysis was performed microscopically by searching cysts and trophozoites in direct wet mount of PD effluent and after staining smears. Protozoa were found in PD effluent of 10.2% of evaluated PD patients, namely Blastocystis hominis, in 2 patients, and Entamoeba sp., Giardia sp., and Endolimax nana in the other 3 patients, respectively. None of these patients presented clinical signs or symptoms of peritonitis at the time of protozoa screening. Our results demonstrate that PD effluent may be susceptible to asymptomatic protozoa colonization. The clinical impact of this finding should be further investigated.

    Gordonia terrae is a rare cause of clinical infections, with only 23 reported cases. We report the first case of peritoneal dialysis-related peritonitis caused by Gordonia terrae in mainland China. A 52-year-old man developed peritoneal dialysis-related peritonitis and received preliminary antibiotic treatment. After claiming that his symptoms had been resolved, the patient insisted on being discharged (despite our recommendations) and did not receive continued treatment after leaving the hospital. A telephone follow-up with the patient's relatives revealed that the patient died 3 months later. Routine testing did not identify the bacterial strain responsible for the infection, although matrix-assisted laser desorption/ionization time-of-flight mass spectrometry identified the strain as Gordonia rubropertincta. However, a 16S rRNA sequence analysis using an isolate from the peritoneal fluid culture revealed that the responsible strain was actually Gordonia terrae. Similar to this case, all previously reported cases have involved a delayed diagnosis and initial treatment failure, and the definitive diagnosis required a 16S rRNA sequence analysis. Changes from an inappropriate antibiotic therapy to an appropriate one have relied on microbiological testing and were performed 7-32 days after the initial treatment. The findings from our case and the previously reported cases indicate that peritoneal dialysis-related peritonitis caused by Gordonia terrae can be difficult to identify and treat. It may be especially challenging to diagnose these cases in countries with limited diagnostic resources.

    Here the authors report a case of refractory peritonitis leading to multiple hospitalizations and the loss of peritoneal dialysis access in a patient on automated peritoneal dialysis, caused by Asaia bogorensis, a bacterium not previously described as a human pathogen. This organism was identified by sequence analysis of the 16S ribosomal RNA gene. Unusual microbial agents may cause peritonitis, and molecular microbiological techniques are important tools for identifying these agents.

  8. Comparing the incomparable: hemodialysis versus peritoneal dialysis in observational studies.

    PubMed

    2004-01-01

    A randomized trial comparing survival in hemodialysis and peritoneal dialysis remains a utopian aspiration. Dialysis is still relatively rare on a population basis, and a natural tension exists between desirability and feasibility in terms of quality of evidence. In practice, it is very difficult to perform prospective comparisons with large groups of contemporary representative subjects, and much of the literature comes from retrospective national registries. This article considers several questions to address when trying to compare the outcomes of peritoneal dialysis and hemodialysis. Prognostic similarity at baseline is a fundamental issue. Traditionally, adjustment for known prognostic factors has been used in an attempt to minimize the bias caused by nonrandom treatment assignment. Propensity scores have been suggested to be superior, and matched-case analysis may also be a useful method for comparison. Other questions include, when, in relation to starting dialysis, to start the observation clock; the definition and handling of switches of dialysis therapy; and the decision to censor at transplantation. Finally, comparisons are complicated by hazards ratios that vary over time, and time-segmented analysis is obligatory. Many types of analytical approaches are needed to begin to appreciate outcome disparities between dialysis therapies.

    Severe peritonitis causing death is one of the most devastating complications of peritoneal dialysis (PD). Since the predictive value of C-reactive protein (CRP) in PD fluid has not been assessed, the objective of the present study is to evaluate its predictive value and clinical correlation in patients on PD with peritonitis. One hundred and twenty patients on continuous ambulatory PD (CAPD) were enrolled and their serum and fluid CRP (Fl. CRP) were evaluated at the start of CAPD. All patients who developed peritonitis were further evaluated for serum and fluid CRP. The patients were categorized into four groups, namely: normal patients (control group), patients with peritonitis, patients with peritonitis leading to catheter removal, and death due to peritonitis. Sixty-five patients developed peritonitis of whom, catheter removal was performed in eight patients. Five patients died due to peritonitis-related complications. Fl. CRP showed a significant difference among the three groups, unlike S. CRP. Estimation of CRP in the peritoneal fluid may be a useful marker to monitor the onset of peritonitis.

    ♦ As an immune system regulator, vitamin D is commonly deficient among patients on peritoneal dialysis (PD), which may contribute to their impaired immune function and increased risk for PD-related peritonitis. In this study, we aimed to investigate whether vitamin D deficiency could predict the risk of peritonitis in a prospective cohort of patients on PD. ♦ We collected 346 prevalent and incident PD patients from 2 hospitals. Baseline demographic data and clinical characteristics were recorded. Serum 25-hydroxyvitamin D (25[OH]D) was measured at baseline and prior to peritonitis. The mean doses of oral active vitamin D used during the study period were also recorded. The outcome was the occurrence of peritonitis. ♦ The mean age of patients and duration of PD were 58.95 ± 13.67 years and 28.45 (15.04 - 53.37) months, respectively. Baseline 25(OH)D level was 16.15 (12.13 - 21.16) nmol/L, which was closely associated with diabetic status, longer PD duration, malnutrition, and inflammation. Baseline serum 25(OH)D predicted the occurrence of peritonitis independently of active vitamin D supplementation with a hazard ratio (HR) of 0.94 (95% confidence interval [CI] 0.90 - 0.98) after adjusting for recognized confounders (age, gender, dialysis duration, diabetes, albumin, residual renal function, and history of peritonitis). Compared to the low tertile, middle and high 25(OH)D level tertiles were associated with a decreased risk for peritonitis with HRs of 0.54 (95% CI 0.31 - 0.94) and 0.39 (95% CI 0.20 - 0.75), respectively. ♦ Vitamin D deficiency evaluated by serum 25(OH)D rather than active vitamin D supplementation is closely associated with a higher risk of peritonitis.

    Peritonitis is a common serious complication of peritoneal dialysis that results in considerable morbidity, mortality, and health care costs. It also significantly limits the use of this important dialysis modality. Despite its importance as a patient safety issue, peritonitis practices and outcomes vary markedly and unacceptably among different centers, regions, and countries. This article reviews peritonitis risk factors, diagnosis, treatment, and prevention, particularly focusing on potential drivers of variable practices and outcomes, controversial or unresolved areas, and promising avenues warranting further research. Potential strategies for augmenting the existing limited evidence base and reducing the gap between evidence-based best practice and actual practice also are discussed. Crown Copyright © 2014.

    1997-08-01

    The use of the "peritonitis rate" in the management of patients undergoing peritoneal dialysis is assuming importance in comparing the prowess of facilities, care givers and new innovations. For this to be a meaningful outcome measure, the type of infection (causative pathogen) must have less clinical significance than the number of infections during a time interval. The natural history of Staphylococcus aureus, pseudomonas, and fungal peritonitis would not support that the outcome of an episode of peritonitis is independent of the causative pathogen. Could this concern be extended to other more frequently occurring pathogens? To address this, the Network 9 Peritonitis Study identified 530 episodes of single organism peritonitis caused by a gram positive organism and 136 episodes caused by a single non-pseudomonal gram negative (NPGN) pathogen. Coincidental soft tissue infections (exit site or tunnel) occurred equally in both groups. Outcomes of peritonitis were analyzed by organism classification and by presence or absence of a soft tissue infection. NPGN peritonitis was associated with significantly more frequent catheter loss, hospitalization, and technique failure and was less likely to resolve regardless of the presence or absence of a soft tissue infection. Hospitalization and death tended to occur more frequently with enterococcal peritonitis than with other gram positive peritonitis. The outcomes in the NPGN peritonitis group were significantly worse (resolution, catheter loss, hospitalization, technique failure) compared to coagulase negative staphylococcal or S. aureus peritonitis, regardless of the presence or absence of a coincidental soft tissue infection. Furthermore, for the first time, the poor outcomes of gram negative peritonitis are shown to be independent of pseudomonas or polymicrobial involvement or soft tissue infections. The gram negative organism appears to be the important factor. In addition, the outcome of peritonitis caused by S. aureus

    ♦ The quality of the peritoneal membrane can deteriorate over time. Exposure to glucose-based dialysis solutions is the most likely culprit. Because peritonitis is a common complication of peritoneal dialysis (PD), distinguishing between the effect of glucose exposure and a possible additive effect of peritonitis is difficult. The aim of the present study was to compare the time-course of peritoneal transport characteristics in patients without a single episode of peritonitis-representing the natural course-and in patients who experienced 1 or more episodes of peritonitis during long-term follow-up. ♦ This prospective, single-center cohort study enrolled incident adult PD patients who started PD during 1990-2010. A standard peritoneal permeability analysis was performed in the first year of PD treatment and was repeated every year. The results in patients without a single episode of peritonitis ("no-peritonitis group") were compared with the results obtained in patients who experienced 1 or more peritonitis episodes ("peritonitis group") during a follow-up of 4 years. ♦ The 124 patients analyzed included 54 in the no-peritonitis group and 70 in the peritonitis group. The time-course of small-solute transport was different in the groups, with the peritonitis group showing an earlier and more pronounced increase in the mass transfer area coefficient for creatinine (p = 0.07) and in glucose absorption (p = 0.048). In the no-peritonitis group, the net ultrafiltration rate (NUFR) and the transcapillary ultrafiltration rate (TCUFR) both showed a steep increase from the 1st to the 2nd year of PD that was absent in the peritonitis group. Both groups showed a decrease in the NUFR after year 3. A decrease in the TCUFR occurred only in the peritonitis group. That decrease was already present after the year 1 in patients with severe peritonitis. The time-course of free water transport showed a continuous increase in the patients without peritonitis, but a decrease in the

    ♦ Introduction: Escherichia coli (E. coli) peritonitis is a frequent, serious complication of peritoneal dialysis (PD). The extended-spectrum β-lactamase (ESBL)-producing E. coli peritonitis is associated with poorer prognosis and its incidence has been on continuous increase during the last decades. However, the clinical course and outcomes of E. coli peritonitis remain largely unclear. ♦ Methods: All of the E. coli peritonitis episodes that occurred in our dialysis unit from 2006 to 2011 were reviewed. The polymicrobial episodes were excluded. ♦ Results: In total, ninety episodes of monomicrobial E. coli peritonitis occurred in 68 individuals, corresponding to a rate of 0.027 episodes per patient-year. E. coli was the leading cause (59.2%) of monomicrobial gram-negative peritonitis. ESBL-producing strains accounted for 35.5% of E. coli peritonitis. The complete cure rate and treatment failure rate of E. coli peritonitis were 77.8% and 10.0% respectively. Patients with preceding peritonitis had a higher risk of ESBL production as compared to those without peritonitis history [odds ratio (OR): 5.286; 95% confidence interval (CI): 2.018 - 13.843; p = 0.001]. The risk of treatment failure was significantly increased when the patient had a baseline score of Charlson Comorbidity Index (CCI) above 3 (OR: 6.155; 95% CI: 1.198 - 31.612; p = 0.03), or had diabetes mellitus (OR: 8.457; 95% CI: 1.838 - 38.91; p = 0.006), or hypoalbuminemia (≤ 30g/l) on admission (OR: 13.714; 95% CI: 1.602 - 117.428; p = 0.01). Prolonging the treatment course from 2 to 3 weeks or more reduced the risk of relapse and repeat significantly (p < 0.05). ♦ Conclusions: E. coli peritonitis remains a common complication of PD. The clinical outcomes of E. coli peritonitis are relatively favorable despite the high ESBL rate. A history of peritonitis is associated with increased risk for ESBL development.

    ♦ Biocompatible fluids for peritoneal dialysis (PD) have been introduced to improve dialysis and patient outcome in end-stage renal disease. However, their impact on hydration status (HS), residual renal function (RRF), and dialysis adequacy has been a matter of debate. The aim of the study was to evaluate the influence of a biocompatible dialysis fluid on the HS of prevalent PD patients. ♦ The study population consisted of 18 prevalent PD subjects, treated with standard dialysis fluids. At baseline, 9 patients were switched to a biocompatible solution, low in glucose degradation products (GDPs) (Balance; Fresenius Medical Care, Bad Homburg, Germany). Hydration status was assessed through clinical evaluation, laboratory parameters, echocardiography, and bioimpedance spectroscopy over a 24-month observation period. ♦ During the study period, urine volume decreased similarly in both groups. At the end of the evaluation, there were also no differences in clinical (body weight, edema, blood pressure), laboratory (N-terminal pro-brain natriuretic peptide, NTproBNP), or echocardiography determinants of HS. However, dialysis ultrafiltration decreased in the low-GDP group and, at the end of the study, equaled 929 ± 404 mL, compared with 1,317 ± 363 mL in the standard-fluid subjects (p = 0.06). Hydration status assessed by bioimpedance spectroscopy was +3.64 ± 2.08 L in the low-GDP patients and +1.47 ± 1.61 L in the controls (p = 0.03). ♦ The use of a low-GDP biocompatible dialysis fluid was associated with a tendency to overhydration, probably due to diminished ultrafiltration in prevalent PD patients.

    The diffusion of peritoneal methodology can not be something out of the real organizational context and the regional directive can not be the only means to encourage the diffusion. There is the need to provide effective and sustainable levels of assistance through a clinical scientific support and sharing of best-practises. On one side, the aim is to provide an aid by the centers with great expertise in the methodology, recognized as reference points; on the other side, to establish the shared K.P.I.s (Key Performance Index), to asses the clinical effectiveness and measure the objectives to be achieved, through a modality of valuation to establish the real applicability. For this purpose, a scientific board was founded, composed by the heads of UU.OO, that provide the peritoneal dialysis, to determine which aspects to investigate and identify factors of supply improvement. The selected method was the clinical audit. The analysis of the 2011 data has allowed us to capture the situation of the peritoneal dialysis in the Lazio Region. The formative procedure has enabled the centers to share and standardize protocols and therapeutic procedures, identify the strengths of peritoneal dialysis in the Lazio Region and define the KPIs through whose compare and monitor the centers over time. The conclusive analysis of the audit has enabled to identify a series of activities to be undertaken together in order to improve the situation of the peritoneal dialysis in the Lazio Region. In the following years, surveys will be carried out to verify the KPIs trend.

    ♦ BACKGROUND: Incremental peritoneal dialysis (PD), the gradual introduction of dialysate exchanges at less than full-dose therapy, has been infrequently described in clinical reports. One concern with less than full-dose dialysis is whether urea clearance targets are achievable with an incremental regimen. In this report, we used a large database of PD patients, across all membrane transport types, and performed urea kinetic modeling determinations of possible incremental regimens for an individual membrane type. ♦ METHODS: Using a modified 3-pore model of peritoneal transport, various incremental manual continuous ambulatory PD (CAPD) exchanges employing glucose and/or icodextrin were evaluated. Peritoneal urea clearances from those simulations were added to residual kidney urea clearance for patients with various glomerular filtration rates (GFRs), and the total weekly urea clearance was then compared to the total weekly urea Kt/V target of 1.7. All 4 peritoneal membrane types were modeled. For each simulated prescription, net ultrafiltration and carbohydrate absorption were also calculated. ♦ RESULTS: Incremental CAPD regimens of 2 exchanges a day met adequacy targets if the GFR was 6 mL/min/1.73 m(2) in all membrane types. For regimens employing 3 exchanges a day, Kt/V targets were achieved at GFR levels of 4 to 5 mL/min/1.73 m(2) in high transporters to low transporters but higher tonicity 2.5% glucose solutions or icodextrin were required in some regimens. ♦ CONCLUSIONS: This work demonstrates that with incremental CAPD regimens, urea kinetic targets are achievable in most new starts to PD with residual kidney function. Incremental PD may be a less intrusive, better accepted initial treatment regime and a cost-effective way to initiate chronic dialysis in the incident patient. The key role of intrinsic kidney function in incremental regimens is highlighted in this analysis and would warrant conscientious monitoring. Copyright © 2017 International

    The objective of the present study is to obtain information about the training programme for patients undergoing Domiciliary Peritoneal Dialysis (DPD) in Spain. For the purposes of the study we designed a questionnaire comprising 50 closed-ended items and one open response item. The questionnaire was sent to 104 hospitals and was completed by 78.84% of them (n > or = 82). The average of patients undergoing peritoneal dialysis (PD) in the hospitals under study was 27.6: 15.8 of them receiving Chronic Ambulatory Peritoneal Dialysis (CAPD) and 11.8 Automatic Peritoneal Dialysis (APD). The questionnaire also served to investigate into the training methodology used in the different units, the involvement of the family in the programme, the basic knowledge patients received about Chronic Renal Insufficiency, the procedures associated with the therapy and the preparation they obtained to solve small-scale contingencies and emergency situations as well as the improvement of their quality of life. We also evaluated the training programme of autonomous patients on DPD and at the end of the questionnaire a blank space was left for facilities to add any comments or suggestions they considered relevant. From the results obtained we may conclude that most Spanish hospitals have devised a training planning for patients undergoing PD which helps them or caregivers to perform domiciliary treatment safely, provides them with basic knowledge about the disease and the routine procedures associated with the treatment, enables them to cope with contingencies and emergency situations and improves their quality of life during the dialysis period.

    AIM: To investigate the efficacy of effluent biomarkers for peritoneal deterioration with functional decline in peritoneal dialysis (PD). METHODS: From January 2005 to March 2013, the subjects included 218 PD patients with end-stage renal disease at 18 centers. Matrix metalloproteinase-2 (MMP-2), interleukin-6 (IL-6), hyaluronan, and cancer antigen 125 (CA125) in peritoneal effluent were quantified with enzyme-linked immunosorbent assay. Peritoneal solute transport rate was assessed by peritoneal equilibration test (PET) to estimate peritoneal deterioration. RESULTS: The ratio of the effluent level of creatinine (Cr) obtained 4 h after injection (D) to that of plasma was correlated with the effluent levels of MMP-2 (ρ = 0.74, P < 0.001), IL-6 (ρ = 0.46, P < 0.001), and hyaluronan (ρ = 0.27, P < 0.001), but not CA125 (ρ = 0.13, P = 0.051). The area under receiver operating characteristic curve for the effluent levels of MMP-2, IL-6, and hyaluronan against high PET category were 0.90, 0.78, 0.62, and 0.51, respectively. No patient developed new-onset encapsulating peritoneal sclerosis for at least 1.5 years after peritoneal effluent sampling. CONCLUSION: The effluent MMP-2 level most closely reflected peritoneal solute transport rate. MMP-2 can be a reliable indicator of peritoneal deterioration with functional decline. PMID:26981446

    Continuous ambulatory peritoneal dialysis (PD) has become a treatment modality for end stage renal disease with a peak of its use in 1990 s. The aim of this study was to examine the peritonitis rates, causative organisms and the risk factors of peritonitis in a large group of patients in our center. The study was conducted in the Nephrology Department of a University Hospital in Turkey. Patients in the PD programme between January 2000 and January 2006 were included. Cohort-specific and subject specific peritonitis incidence, and peritonitis-free survival were calculated. Causative organisms and risk factors were evaluated. Totally 620 episodes of peritonitis occurred in 440 patients over the six years period. Peritonitis rates showed a decreasing trend through the years (0.79 episodes/patient-year 2000-2003 and 0.46 episodes/patient-year 2003-2006). Cohort-specific peritonitis incidence was 0.62 episodes/patient-years and median subject-specific peritonitis incidence was 0.44 episodes/patient-years. The median peritonitis-free survival was 15.25 months (%95 CI, 9.45-21.06 months). The proportion of gram-negative organisms has increased from 9.8% to 17.3%. There was a significant difference in the percentage of culture negative peritonitis between the first three and the last three years (53.1% vs. 43.2%, respectively). Peritonitis incidence was higher in patients who had been transferred from HD, who had catheter related infection and who had HCV infection without cirrhosis. Our study showed significant trends in the peritonitis rates, causative organisms and antibiotic resistance. Prior HD therapy, catheter related infections and HCV infection were found to be risk factors for peritonitis.

    Early retraining of patients/caregivers at 3 months after peritoneal dialysis (PD) initiation is recommended to prevent peritonitis. We sought to better understand if the risk of peritonitis was highest early after the initiation of PD and if the risk varied by time on therapy and by organism. Using the multicenter Canadian Baxter POET database, we studied 4,247 incident PD patients. Time on dialysis was divided into 3-month intervals over the first 2 years on PD, with 0 - 3 months serving as the reference period. After creating several organism categories (all organisms, coagulase-negative staphylococcus (CNS), Staphylococcus aureus, streptococcus, Gramnegative, culture-negative, and yeast), time to first peritonitis was analyzed by Kaplan-Meier analysis and using smooth hazard plots. The risk of peritonitis for each of these categories over time was then analyzed in a multivariable model after adjusting for potential confounding variables. The overall risk of peritonitis (all organisms) was greatest in the first 3 months on PD compared with all subsequent 3-month intervals (p = 0.001). Organism-specific analyses revealed an increased risk of culture-negative peritonitis in the first 3 months (p < 0.001) but no increased risk of CNS peritonitis or any of the other pre-specified organism categories. The overall risk of peritonitis was greatest in the first 3 months on PD and was largely driven by an increased risk of culture-negative peritonitis but not by CNS. Better understanding of this increased early peritonitis risk is warranted in order to develop strategies aimed at its prevention.

    Diabetic patients treated by peritoneal dialysis (PD) have been reported to be at an increased risk of peritonitis. This has been attributed to impairment in host defense, visual impairment, disability and muscle wasting, which could compromise ability to safely perform catheter connections. This study aimed to evaluate whether assisted PD is associated with a lower risk of peritonitis in diabetic patients. This was a retrospective study based on data from the French Language Peritoneal Dialysis Registry. We included diabetic patients starting PD between 1 January 2002 and 31 December 2012. The end of the observation period was 31 December 2013. Using complementary regression analysis (Fine and Gray, Hurdle models), we assessed the relationship between peritonitis occurrence, peritonitis number over time and the type of assisted PD. Of the 3598 diabetic patients, there were 2040 patients on nurse-assisted PD. These patients were older, more comorbid and more frequently on continuous ambulatory peritoneal dialysis (CAPD). In the multivariate analysis, nurse assistance was associated with a reduced risk of peritonitis in the Fine and Gray [subdistribution hazard ratio: 0.78 (95% confidence interval, CI, 0.68-0.89)] and in the first component of the Hurdle models [rate ratio: 0.82 (95% CI 0.71-0.93)], but not a lower incidence of peritonitis after an initial episode [rate ratio: 0.82 (95% CI 0.95-1.38)]. Transplant failure, glomerulonephritis and CAPD were associated with an increased risk. In France, nurse-assisted PD is associated with a lower risk of peritonitis in diabetic patients treated by PD but not a lower incidence of peritonitis. © The Author 2016.

    To determine whether solute transfer during peritoneal dialysis is age related and to identify those factors which might explain age-related differences in dialysis kinetics, the peritoneal dialysance of [14C]urea (DU), [3H]inulin (DI), and the permeability index (DR = DI/DU) were examined in six puppies and five adult dogs. Exchange volume of lactated Ringer's (40 ml/kg) and exchange times (30 min) were identical in all studies. Theoretical calculations for urea dialysance for animals of differing body size were made. Assuming the existence of a similar functional peritoneal surface area per kg and the use of similar exchange volumes per kg and dwell times, theoretical values for the urea dialysance per kg for different sized animals were identical. The experimental studies demonstrated that DI per kg and DU per kg were higher in the puppies (0.146 +/- 0.023 and 0.765 +/- 0.054 ml/min kg; X +/- S.E.) than in the adult (0.052 +/- 0.01 and 0.462 +/- 0.05 ml/min/kg) (P less than 0.01). Also, DR was higher in the puppies (0.187 +/- 0.026), than in the adults (0.11 +/- 0.015) (P less than 0.05). The greater values for DI and DU per kg and DR in the young are best explained by the young having an increased peritoneal membrane permeability as well as an increase in functional peritoneal surface area relative to body weight. This increase in solute movement is independent of the dialysis mechanics used in an exchange and reflects age-related differences in the intrinsic characteristics of the peritoneal membrane.

    During the standard heat sterilization process of the lactate-buffered peritoneal dialysis solutions, glucose (an osmotic active substance) degrades to form compounds called glucose degradation products which are cytotoxic and affect the survival of the peritoneal membrane. This case presentation is based on an observation of 224 aseptic peritonitis cases of unknown etiology. For the purpose of clarification, we analyzed the peritoneal dialysis solutions for the presence of acetaldehyde by using a developed and validated high-performance liquid chromatography (HPLC) pre-column derivitazation. The method was validated with respect to validation factors such as linearity, precision, recovery and (LOD). The acetaldehyde level of solutions before heat sterilization was 1.78 ± 2.7 ppm whereas in samples after heat sterilization was about 20 ± 2.07 ppm. Based on the forementioned findings, we hypothesized that the higher levels of acetaldehyde and possibly the other glucose degradation products may have been an etiological factor in these 224 cases of chemical peritonitis. So it is important for the manufacturers to carefully review the heat of sterilization process in the production line.

    Erysipelothrix rhusiopathiae is known as a pathogen of occupational diseases or a zoonosis. We report a case of E. rhusiopathiae peritonitis in a 50-yr-old male undergoing continuous ambulatory peritoneal dialysis (CAPD). He was suffered from mild abdominal pain with a distinctive erysipeloid skin lesion. E. rhusiopathiae was considered to be introduced through a lacerated wound on his hand when he was exposed to contaminated materials. He was treated successfully with a first generation cephalosporin. To our knowledge, CAPD peritonitis due to E. rhusiopathiae is very rare, and this is a report of the first case in Asia.

    ♦ Background: Peritonitis in peritoneal dialysis (PD) patients can lead to technique failure and contributes to infection-related mortality. Peritonitis prevention and optimization of treatment are therefore important in the care for PD patients. In the present study, we analyzed the incidence of peritonitis, causative pathogens, clinical outcomes, and trends in relation to three major treatment changes that occurred from 1979 onward: use of a disconnect system since 1988, daily mupirocin at the exit-site since 2001, and exclusive use of biocompatible dialysis solutions since 2004. ♦ Methods: In this analysis of prospectively collected data, we included peritonitis episodes from the start of PD at our center in August 1979 to July 2010. Incident PD patients were allocated to one of four groups: Group 1 - 182 patients experiencing 148 first peritonitis episodes between 1979 and 1987, before the introduction of the disconnect system; Group 2 - 352 patients experiencing 239 first episodes of peritonitis between 1988 and 2000, before implementation of daily mupirocin application at the catheter exit-site; Group 3 - 79 patients experiencing 50 first peritonitis episodes between 2001 and 2003, before the switch to biocompatible solutions; and Group 4-118 patients experiencing 91 first peritonitis episodes after 2004. Cephradine was used as initial antibiotic treatment. ♦ Results: In 32 years, 731 adult patients started PD, and 2234 episodes of peritonitis in total were diagnosed and treated. Of those episodes, 88% were cured with medical treatment only, and 10% resulted in catheter removal. In 3% of the episodes, the patient died during peritonitis. Median time to a first peritonitis episode increased from 40 days for group 1 to 150 for group 2, 269 for group 3, and 274 for group 4. The overall peritonitis rate and the gram-positive and gram-negative peritonitis rates showed a time-trend of decline. However, the duration of antibiotic treatment increased over time

    Refractory peritonitis remains a thorny issue for patients with chronic peritoneal dialysis (PD). Shortly after catheter removal, some patients develop persistent peritoneal inflammation and ascites formation, which require percutaneous drainage for symptom relief. Our study aimed at finding the risk factors for this kind of event. A total of 47 PD patients complicated with refractory peritonitis who underwent catheter removal between January 2009 and December 2011 were enrolled in this study. Data were compared between patients with and without the development of symptomatic ascites requiring drainage during hospitalization. Among the 47 refractory peritonitis patients, 15 patients developed symptomatic ascites that needed further drainage shortly after catheter removal during hospitalization. The following factors were associated with an increased risk: longer dialysis duration, higher peritoneal Kt/V urea, and a significant rise in serum C-reactive protein (CRP) level after catheter removal. These patients had a prolonged hospital stay (62 vs 21 days, P < 0.001) and a significantly higher risk of recurrent loculated ascites during subsequent 6 months of follow-up (33.3 vs 6.2 %, P = 0.022) compared with patients who did not develop ascites requiring drainage during hospitalization. A significant portion of patients with refractory PD peritonitis experienced ascites requiring drainage shortly after catheter removal, which led to a prolonged hospitalization. Whether routine drain placement at the time of catheter removal for this high-risk group would be of benefit warrants further prospective studies.

    Paecilomyces variotii (P. variotii) is an extremely rare cause of continuous ambulatory peritoneal dialysis (CAPD) peritonitis. When diagnosed, it usually portends poor prognosis. Patient's survival depends on early laboratory diagnosis and proper treatment. We herein report a P. variotii peritonitis in a patient on CAPD which is a quite rare clinical entity. Laboratory diagnosis was confirmed via both morphological analysis and DNA sequencing. Antifungal susceptibility tests were performed and interpreted according to the Clinical Laboratory Standards Institute M38-A2 guidelines. After laboratory diagnosis, the patient was treated succesfully with liposomal amphotericin B and itraconazole combination and the peritoneal catheter was removed. This case is worthy of reporting since P. variotii is an uncommon cause of peritonitis and leads to dilemmas in both laboratory diagnosis and treatment strategies.

    ♦ Background: To understand how peritoneal dialysis (PD) was being used in Italy in 2005 and 2008, a census of all centers was carried out. ♦ Methods: In 2005 and 2008, data were collected from, respectively, 222 and 223 centers, with respect to 4432 and 4094 prevalent patients. ♦ Results: In the two periods, the PD incidence remained stable (24.3% vs 22.9%), varying from center to center. Continuous ambulatory PD (CAPD) was the main initial method (55%), but APD was more widespread among prevalent patients (53%). Among patients returning to dialysis from transplantation (Tx), PD was used in 10%. The use of incremental CAPD increased significantly from 2005 to 2008, in terms both of the number of centers (27.0% vs 40.9%) and of patients (13.6% vs 25.7%). Late referrals remained stable at 28%, with less use of PD. The overall drop-out rate (episodes/100 patient-years) remained unchanged (31.0 vs 32.8), with 13.1 and 12.9 being the result of death, and 11.8 and 12.4 being the result of a switch to hemodialysis, mainly after peritonitis. A dialysis partner was required by 21.8% of the PD patients. The incidence of peritonitis was 1 episode in 36.5 and 41.1 patient-months, with negative cultures occurring in 17.1% of cases in both periods. The incidence of encapsulating peritoneal sclerosis (episodes/100 patient-years) was 0.70, representing 1.26% of patients treated. The catheter types used and the sites and methods of insertion varied widely from center to center. ♦ Conclusions: These censuses confirm the good results of PD in Italy, and provide insight into little-known aspects such as the use of incremental PD, the presence of a dialysis partner, and the incidence of encapsulating peritoneal sclerosis.

    Purpose Relatively little is known on the microbiology, risk factors and outcomes of peritoneal dialysis (PD)-associated peritonitis in Korean children. We performed this study in order to evaluate the incidence, treatment and clinical outcomes of peritonitis in pediatric PD patients at Severance Hospital. Materials and Methods We analyzed data from 57 PD patients younger than 18 years during the period between June 1, 1986 and December 31, 2011. The collected data included gender, age at commencement of PD, age at peritonitis, incidence of peritonitis, underlying causes of end stage renal disease, microbiology of peritonitis episodes, antibiotics sensitivity, modality and outcomes of PD. Results We found 56 episodes of peritonitis in 23 of the 57 PD patients (0.43 episodes/patient-year). Gram-positive bacteria were the most commonly isolated organisms (40 episodes, 71.4%). Peritonitis developed in 17 patients during the first 6 months following initiation of PD (73.9%). Peritonitis episodes rarely resulted in relapse or the need for permanent hemodialysis and no patient deaths were directly attributable to peritonitis. Antibiotic regimens included cefazolin+tobramycin from the years of 1986 to 2000 and cefazolin+ceftazidime from the years of 2001 to 2011. While antibiotic therapy was successful in 48 episodes (85.7%), the treatment was ineffective in 8 episodes (14.3%). The rate of continuous ambulatory PD (CAPD) peritonitis was statistically higher than that of automated PD (APD) (p=0.025). Conclusion Peritonitis was an important complication of PD therapy and we observed a higher incidence of PD peritonitis in patients with CAPD when compared to APD. PMID:23709435

    We have previously demonstrated that daily exposure to dialysis fluid results in significantly increased peritoneal lymphatic flow. In this study, we investigated if daily intraperitoneal infusion of saline (isotonic, glucose free) could cause similar changes. Sixteen male SD rats received daily infusion (i.p.) of 20 ml saline for ten days (Saline group). Twenty-four hours after the last infusion, a 4 hour dwell study using 25 ml 3.86% glucose dialysis solution with frequent dialysate and blood sampling was done in each rat as well as in rats which did not receive daily infusion (Control, n=8). Radiolabeled human albumin (RISA) was added to the solution as an intraperitoneal volume marker. Radioactivity, glucose, urea, sodium, and potassium were measured for each sample. In a separate study, the RISA absorption to peritoneal tissue was also determined. The net ultrafiltration was significantly decreased in the daily infusion group (p<0.05). However, the apparent volume at 3 minutes of the dwell was markedly increased; this was due to a significant increase in the RISA binding (1.5-12.0% in the Saline group vs. 0.45-1.12% in the Control group) to peritoneal tissues as assessed by measurement of RISA recovery at 3 min of the dwell. This resulted in a significant overestimation both of the intraperitoneal volume (IPV) at 3 min and the (apparent) fluid absorption rate (as estimated by the transport of RISA out of peritoneal cavity): 0.087+/-0.026 ml/min in the Saline group vs. 0.052+/-0.007 ml/min in the Control group, p<0.001. The direct lymphatic flow as estimated by the clearance of RISA to plasma (which should not be affected by the RISA binding) also increased markedly (0.021+/-0.005 ml/min in the Saline group vs. 0.008+/-0.001 ml/min in the control group). There was no significant difference in the D/P values for small solutes (urea, sodium, potassium, urate) and D/D0 for glucose between the two groups. 1) Daily infusion of physiological saline into peritoneal

    Background The first episode of peritonitis affects survival of the peritoneal membrane as a medium for dialysis as well as survival of patients. The aim of this study is to investigate risk factors associated with the first episode of peritonitis in Southern Chinese continuous ambulatory peritoneal dialysis (CAPD) patients. Methods This is a single-center, retrospective, cohort study. All incident CAPD patients from 1 January 2006 to 31 December 2010 were recruited, and followed up until their first episode of peritonitis or 31 December, 2012. Baseline demographic, socioeconomic, clinical and laboratory data were collected. Cox proportional model was used to determine the factors associated with the first episode of peritonitis. Results In a cumulative 30756.5 patient-months follow-up (the median vintage 26.1 months) of 1117 CAPD patients, 309(27.7%) patients presented the first episodes of peritonitis. The cumulative peritonitis-free survival was 86.2%, 78.1%, 71.4% and 57.8% at 1, 2, 3 and 5 year, respectively. The multivariate analysis showed that factors associated with risk for the first episode of peritonitis were elderly patients (>65 years) [hazard ratio (HR) = 1.427, 95% confidence interval (CI) = 1.051 to 1.938, P = 0.023], male(HR = 1.315, 95% CI = 1.028 to 1.684, P = 0.030), lower education level (HR = 1.446, 95% CI: 1.127 to 1.855, P = 0.004) and albumin <38g/L (HR = 1.425, 95% CI: 1.112 to 1.825, P = 0.005). Conclusions Older age, male, lower educational level and hypoalbuminemia at the commencement of PD were the risk factors associated with the first episode of peritonitis in Southern Chinese CAPD patients.

    ♦ The aim of the present study was to investigate the relationship between socio-economic status (SES) and peritoneal dialysis (PD)-related peritonitis. ♦ Associations between area SES and peritonitis risk and outcomes were examined in all non-indigenous patients who received PD in Australia between 1 October 2003 and 31 December 2010 (peritonitis outcomes). SES was assessed by deciles of postcode-based Australian Socio-Economic Indexes for Areas (SEIFA), including Index of Relative Socio-economic Disadvantage (IRSD), Index of Relative Socio-economic Advantage and Disadvantage (IRSAD), Index of Economic Resources (IER) and Index of Education and Occupation (IEO). ♦ 7,417 patients were included in the present study. Mixed-effects Poisson regression demonstrated that incident rate ratios for peritonitis were generally lower in the higher SEIFA-based deciles compared with the reference (decile 1), although the reductions were only statistically significant in some deciles (IRSAD deciles 2 and 4 - 9; IRSD deciles 4 - 6; IER deciles 4 and 6; IEO deciles 3 and 6). Mixed-effects logistic regression showed that lower probabilities of hospitalization were predicted by relatively higher SES, and lower probabilities of peritonitis-associated death were predicted by less SES disadvantage status and greater access to economic resources. No association was observed between SES and the risks of peritonitis cure, catheter removal and permanent hemodialysis (HD) transfer. ♦ In Australia, where there is universal free healthcare, higher SES was associated with lower risks of peritonitis-associated hospitalization and death, and a lower risk of peritonitis in some categories.

    Background Fungal peritonitis is a serious complication of peritoneal dialysis (PD) therapy with the majority of patients ceasing PD permanently. The aims of this study were to identify risk factors and clinical associations that may discriminate between fungal from bacterial peritonitis. Methods We retrospectively identified episodes of fungal peritonitis from 2001–2010 in PD patients at Liverpool and Westmead Hospitals (Australia). Fungal peritonitis cases were matched in a 1∶2 ratio with patients with bacterial peritonitis from each institution's dialysis registry, occurring closest in time to the fungal episode. Patient demographic, clinical and outcome data were obtained from the medical records. Results Thirty-nine episodes of fungal peritonitis (rate of 0.02 episodes per patient-year of dialysis) were matched with 78 episodes of bacterial peritonitis. Candida species were the commonest pathogens (35/39; 90% episodes) with Candida albicans (37%), Candida parapsilosis (32%) and Candida glabrata (13%) the most frequently isolated species. Compared to bacterial peritonitis, fungal peritonitis patients had received PD for significantly longer (1133 vs. 775 catheter-days; p = 0.016), were more likely to have had previous episodes of bacterial peritonitis (51% vs. 10%; p = 0.01), and to have received prior antibacterial therapy (51% vs. 10%; p = 0.01). Patients with fungal peritonitis were less likely to have fever and abdominal pain on presentation, but had higher rates of PD catheter removal (79% vs. 22%; p<0.005), and permanent transfer to haemodialysis (87% vs. 24%; p<0.005). Hospital length of stay was significantly longer in patients with fungal peritonitis (26.1 days vs. 12.6 days; p = 0.017), but the all-cause 30-day mortality rate was similar in both groups. Fluconazole was a suitable empiric antifungal agent; with no Candida resistance detected. Conclusion Prompt recognition of clinical risk factors, initiation of antifungal therapy

    Nine nurses were interviewed to determine nurses' experiences of teaching patients to use continuous ambulatory peritoneal dialysis (CAPD). The material was analyzed using content analysis. Data were sorted into four themes and ten subthemes. The themes were presented as follows: Importance of language, individualized teaching, teaching needs and structure of care in teaching. The findings highlighted important insights into how nurses experience teaching patients to perform CAPD. The study revealed some barriers for the nurses during teaching. The major barrier was shortage of Arabic speaking nursing staff. Incidental findings involved two factors that played an important role in teaching, retraining and a special team to perform pre-assessments, including home visits. In conclusion, the findings of this study showed several factors that are considered as barriers for the nurses during teaching the CAPD patients and the need to improve the communication and teaching in the peritoneal dialysis units, including the importance of individualized teaching.

    Solute transport, predominantly diffusion, across the peritoneum correlates inversely with molecular weight. Provided that the solute is water soluble, not protein bound, not of unusual density, not ionized, does not have a large hydration shell, and is transported from plasma to dialysate, the peritoneal clearance is predictable over the molecular weight range from 60 to 11,000 daltons. Transport reates that deviate from the predicted can be explained by known physical properties of particular solutes.

    When compared to hemodialysis, peritoneal dialysis is very simple yet low cost method of renal replacement therapy. Series of studies have shown its superiority in preserving residual renal function, postponing uremic complications, maintaining the acid-base balance and achieving better post-transplant outcome in patients treated with this method. Despite obvious advantages, its role in the treatment of chronic kidney disease is still not as important as it should be. Metabolic acidosis is an inevitable complication associated with progressive loss of kidney function. Its impact on mineral and muscle metabolism, residual renal function, allograft function and anemia is very complex but can be successfully managed. The aim of our study was to evaluate the efficiency in preserving the acid-base balance in patients undergoing peritoneal dialysis at Zagreb University Hospital Center. Twenty-eight patients were enrolled in the study. The mean time spent on the treatment was 32.39 ± 43.43 months. Only lactate-buffered peritoneal dialysis fluids were used in the treatment. Acid-base balance was completely maintained in 73.07% of patients; 11.54% of patients were found in the state of mild metabolic acidosis, and the same percentage of patients were in the state of mild metabolic alkalosis. In one patient, mixed alkalosis with respiratory and metabolic component was present. The results of this study showed that acid-base balance could be maintained successfully in patients undergoing peritoneal dialysis, even only with lactate-buffered solutions included in the treatment, although they were continuously proclaimed as inferior in comparison with bicarbonate-buffered ones. In well educated and informed patients who carefully use this method, accompanied by the attentive and thorough care of their physicians, this method can provide quality continuous replacement of lost renal function as well as better quality of life.

    Background: Patients with chronic diseases are known to benefit from exercise. Despite a lack of compelling evidence, patients with end-stage kidney disease treated with peritoneal dialysis are often discouraged from participating in exercise programs that include resistance training due to concerns about the development of hernias and leaks. The actual effects of physical activity with or without structured exercise programs for these patients remain unclear. The purpose of this study is to more completely define the risks and benefits of physical activity in the end-stage kidney disease population treated with peritoneal dialysis. Methods/design: We will conduct a systematic review examining the effects of physical activity on end-stage kidney disease patients treated with peritoneal dialysis. For the purposes of this review, exercise will be considered a purposive subcategory of physical activity. The primary objective is to determine if physical activity in this patient population is associated with improvements in mental health, physical functioning, fatigue and quality of life and if there is an increase in adverse outcomes. With the help of a skilled librarian, we will search MEDLINE, EMBASE, CINAHL, and Cochrane Central Register of Controlled Trials for randomized trials and observational studies. We will include adult end-stage kidney disease patients treated with peritoneal dialysis that have participated in an exercise training program or had their level of physical activity assessed directly or by self-report. The study must include an assessment of the association between physical activity and one of our primary or secondary outcomes measures. We will report study quality using the Cochrane Risk of Bias Assessment Tool for randomized controlled trials and the Newcastle–Ottawa Scale for observational studies. Quality across studies will be assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The

    Peritoneal dialysis (PD) is frequently complicated by high rates of peritonitis, which result in hospitalization, technique failure, transfer to hemodialysis, and increased mortality. Early diagnosis, and identification of contributing factors are essential components to increasing effectiveness of care. In previous reports, neutrophil gelatinase-associated lipocalin (NGAL), a lipocalin which is a key player in innate immunity and rapidly detectable in peritoneal dialysis effluent (PDE), has been demonstrated to be a useful tool in the early diagnosis of peritonitis. This study investigates predictive value of PDE NGAL concentration as a prognostic indicator for PD-related peritonitis. A case-control study with 182 PD patients was conducted. Plasma and PDE were analyzed for the following biomarkers: C-reactive protein (CRP), blood procalcitonin (PCT), leucocytes and NGAL in PDE. The cases consisted of patients with suspected peritonitis, while controls were the patients who came to our ambulatory clinic for routine visits without any sign of peritonitis. The episodes of peritonitis were defined in agreement with International Society for Peritoneal Dialysis guidelines. Continuous variables were presented as the median values and interquartile range (IQR). Mann-Whitney U test was used to compare continuous variables. Univariate and multivariate logistic regression were used to evaluate the association of biomarkers with peritonitis. Receiver operating characteristic (ROC) curve analysis was used to calculate area under curve (AUC) for biomarkers. Finally we evaluated sensitivity, and specificity for each biomarker. All statistical analyses were performed with SPSS version 17.0 (SPSS Inc., Chicago, IL, USA). During the 19-month study, of the 182 patients, 80 had a clinical diagnosis of peritonitis. C-reactive protein levels (p < 0.001), PCT (p < 0.001), NGAL in PDE (p < 0.001), and white blood cells (WBC) in PDE (p < 0.001) were all significantly different in

    Introduction The impact of peritoneal dialysis modality on patient survival and peritonitis rates is not fully understood, and no large-scale randomized clinical trial (RCT) is available. In the absence of a RCT, the use of an advanced matching procedure to reduce selection bias in large cohort studies may be the best approach. The aim of this study is to compare automated peritoneal dialysis (APD) and continuous ambulatory peritoneal dialysis (CAPD) according to peritonitis risk, technique failure and patient survival in a large nation-wide PD cohort Methods This is a prospective cohort study that included all incident PD patients with at least 90 days of PD recruited in the BRAZPD study. All patients who were treated exclusively with either APD or CAPD were matched for 15 different covariates using a propensity score calculated with the nearest neighbor method. Clinical outcomes analyzed were overall mortality, technique failure and time to first peritonitis. For all analysis we also adjusted the curves for the presence of competing risks with the Fine and Gray analysis. Results After the matching procedure, 2,890 patients were included in the analysis (1,445 in each group). Baseline characteristics were similar for all covariates including: age, diabetes, BMI, Center-experience, coronary artery disease, cancer, literacy, hypertension, race, previous HD, gender, pre-dialysis care, family income, peripheral artery disease and year of starting PD. Mortality rate was higher in CAPD patients (SHR1.44 CI95%1.21-1.71) compared to APD, but no difference was observed for technique failure (SHR0.83 CI95%0.69-1.02) nor for time till the first peritonitis episode (SHR0.96 CI95%0.93-1.11). Conclusion In the first large PD cohort study with groups balanced for several covariates using propensity score matching, PD modality was not associated with differences in neither time to first peritonitis nor in technique failure. Nevertheless, patient survival was significantly better

    In an attempt to evaluate the attitude of physicians towards establishing and maintaining a peritoneal dialysis (PD) program in the Kingdom of Saudi Arabia (KSA), we sent a questionnaire to 160 physicians; the heads of the 148 active dialysis centers in the KSA and 12 other consultants working in these centers. This covered decision makers in 109 centers (73.6%) in the Ministry of Health (MOH), 18 (12.2%) in Governmental-non-MOH centers, and 21 (14.2%) in private hospitals that, together, care for a population of more than 7300 patients on chronic hemodialysis (HD) and 559 on PD. The study was performed between September and December 2005. A total of 145 of the 160 physicians (90.6%) from 141 dialysis centers (95.2%) answered the questionnaire. There were 81 respondents (56.3%) who believed that follow-up of the PD patients should be available in all the dialysis centers, 80 (55.2%) would like to have a PD clinic at their centers, and only 20 (13.8%) had PD clinics in their centers. However, 93 (66.4%) respondents did not request from the administration of their hospitals to open a PD clinic and 62 (44.6%) admitted to having no expertise in managing the patients on PD, while 53 (38.1%) claimed that they did not have enough space in their dialysis centers to start a PD program. Regarding training and expertise, 57 (40.7%), 58 (43.3%), 48 (35.6%) and 72 (52.9%) physicians had training in continuous ambulatory PD (CAPD), intermittent peritoneal dialysis (IPD), automated peritoneal dialysis (APD) or continuous cyclic peritoneal dialysis (CCPD), and acute PD, respectively. The comparisons between the health sectors in the KSA showed that MOH had significantly less active PD programs, and this reflected tremendously on the knowledge of the staff. Our survey indicates that the current practices concerning the PD programs in the KSA are modest, and that a new strategy is required to spread this modality of therapy horizontally in all the dialysis centers, and vertically by

    Chronic peritoneal dialysis (CPD) has been utilized in the treatment of children since 1989 in Turkey. The aims of this study were to summarize our experience with CPD in children and to establish a pediatric registry data system in Turkey. Standard questionnaires were sent to all pediatric CPD centers. 514 patients treated between 1989 and 2002 in 12 pediatric centers were enrolled in the study. Reflux nephropathy was the most common (18.1%) cause of renal failure. Mean age at dialysis initiation was 10.1+/-4.6 years. Mean duration of dialysis was 24.1+/-20.5 months. Continuous ambulatory peritoneal dialysis (CAPD) was the first CPD modality for 476 (92.6%) patients, 142 of whom switched to automated peritoneal dialysis (APD) during follow-up. Currently, 47.3% of the patients are still on CPD, 15.4% were transplanted, 13.2% switched to hemodialysis, 16.7% died. The patient and technique survivals were 90% and 95% at one year and 70% and 69% at five years, respectively. The survival was significantly shorter in the youngest age group (0-24 months) compared to those in older age groups (p=0.000). We herein report the first results of the TUPEPD study providing information on demographic data and survival of pediatric CPD patients. As opposed to clear recommendations in favor of APD, there is a clear preponderance of CAPD in our pediatric CPD population. That vesicoureteral reflux (VUR) is still the leading cause of renal failure is a distressing finding. Remarkably lower survival rates and transplantation ratios are as striking and distressing as the high incidence of VUR among the causes of ESRD. We conclude that we must make a great effort to achieve better results and to change these undesirable events.

    Malnutrition is a negative predictive factor for survival in end stage renal disease (ESRD) patients. Coincidence of malnutrition, inflammation and atherosclerosis (MIA syndrome) in the dialysis population is an exceptionally poor outcome event. Due to flexibility, ease of performance and reproducibility, clinical scales are of particular value in assessment of nutritional status in ESRD patients. The aim of the present study was to evaluate the clinical value of Mini Nutritional Assessment (MNA) in peritoneal dialysis (PD) patients. Nutritional status was assessed in 41 peritoneal dialysis patients by means of the MNA scale and malnutrition inflammation score (MIS). Some other clinical and laboratory parameters associated with nutritional status were analyzed. Patients were followed up for 30 months. In the analyzed group of patients a good nutritional state was diagnosed in 22 patients (54%), risk of malnutrition in 17 (41%) and malnutrition in 2 patients (5%) based on the MNA scale. A strong correlation between MNA based nutritional status and MIS was found (r = -0.85, p < 0.01, ANOVA, p < 0.01). Differences in time on dialysis, body mass index, concentration of albumin, cholesterol and triglycerides were noted between at risk/malnourished and well-nourished (according to MNA) patients. Statistically significant factors determining survival of patients by Cox proportional hazard analysis were age (HR 1.07), being at risk/malnourished according to MNA (HR 5.7), MIS (HR 1.2), and albumin (HR 0.13). The MNA scale is a valuable, clinically suitable tool for assessment of nutritional status in peritoneal dialysis patients. Risk of malnutrition and malnutrition diagnosed by MNA identifies patients at high mortality risk.

    Background: A 66-year-old male with a history of severe ischemic myopathy and renal failure underwent a combined heart and kidney transplant. Postoperative failure of the transplanted kidney eventually led to the need for peritoneal dialysis (PD). Methods: After one month, the PD catheter was laparoscopically repositioned after it was found to have migrated from its correct position in the pelvis and twisted and clogged in the omentum. After one more month, the same complication recurred. Laparoscopy was again used to clear the clogged catheter and reposition it. This time, a testicular prosthesis was sewn to the catheter and used as an anchoring weight for the proper position in the pelvis. Results: Six months after anchoring with the testicular prosthesis, the peritoneal dialysis catheter continues to function appropriately, and the patient has no complaints. Conclusions: Mal-positioned peritoneal dialysis catheters may be repositioned and anchored by using a testicular prosthesis in the event that weighted catheters are not available. PMID:21605534

  8. Residual Renal Function in Children Treated with Chronic Peritoneal Dialysis

    PubMed Central

    2013-01-01

    Residual renal function (RRF) in patients with end-stage renal disease (ESRD) receiving renal replacement therapy is defined as the ability of native kidneys to eliminate water and uremic toxins. Preserved RRF improves survival and quality of life in adult ESRD patients treated with peritoneal dialysis. In children, RRF was shown not only to help preserve adequacy of renal replacement therapy but also to accelerate growth rate, improve nutrition and blood pressure control, reduce the risk of adverse myocardial changes, facilitate treatment of anemia and calcium-phosphorus balance abnormalities, and result in reduced serum and dialysate fluid levels of advanced glycation end-products. Factors contributing to RRF loss in children treated with peritoneal dialysis include the underlying renal disease such as hemolytic-uremic syndrome and hereditary nephropathy, small urine volume, severe proteinuria at the initiation of renal replacement therapy, and hypertension. Several approaches can be suggested to decrease the rate of RRF loss in pediatric patients treated with chronic peritoneal dialysis: potentially nephrotoxic drugs (e.g., aminoglycosides), episodes of hypotension, and uncontrolled hypertension should be avoided, urinary tract infections should be treated promptly, and loop diuretics may be used to increase salt and water excretion.

    Escherichia coli is the most common cause of Gram-negative peritonitis resulting in peritoneal function deterioration as well as poor clinical outcome in continuous ambulatory peritoneal dialysis (PD) patients. In this study, we analyzed the phylogenetic background and genetic profile of the E. coli isolates and sought to determine the characteristics of specific bacteria associated with peritonitis. E. coli isolates from 56 episodes of peritonitis in 46 PD patient cases and rectal isolates from 57 matched PD control patient cases were compared for both phylogenetic groups and the presence of virulence factors (VFs). There were no significant differences in terms of demographic data between the peritonitis and control groups. Peritonitis isolates exhibited a significantly greater prevalence of 8 VFs. In multivariate logistic regression analysis, kpsMT II (group 2 capsule synthesis) was the strongest VF predictor of peritonitis (OR = 8.02; 95%CI = 3.18-20.25; P < 0.001), followed by traT (serum-resistance-associated outer membrane protein) (OR = 3.83; 95%CI = 1.33-11.03; P = 0.013). The pathogenic groups of E. coli contained a higher concentration of individual VFs compared to the commensal groups. The prevalence of pathogenic E. coli was much higher in peritoneal isolates than rectal isolates (64.3 vs 31.6%, P = 0.001). Our results indicate that the E. coli peritonitis and rectal isolates are different in PD patients. The specific VFs associated with peritonitis isolates may directly contribute to the pathogenesis of peritonitis.

    The pharmacokinetics of ceftizoxime were studied in 12 patients on continuous ambulatory peritoneal dialysis. After a 3-g intravenous dose, the steady-state volume of distribution was 0.23 +/- 0.05 liter kg-1, with an elimination half-life of 9.7 +/- 5.1 h. The peritoneal clearance of ceftizoxime (2.8 +/- 0.7 ml min-1) contributed modestly to the overall serum clearance of the drug (17.1 +/- 7.4 ml min-1) and was greater than the renal clearance (0.8 +/- 0.8 ml min-1). The peritoneal concentration rose to 91 +/- 29 micrograms ml-1 at 6 h, which was 0.61 +/- 0.17 of the serum concentration. A 3-g intravenous dose of ceftizoxime given every 48 h would result in adequate activity against most susceptible organisms, but more frequent dosing may be necessary for less susceptible organisms.

    PubMed

    2009-01-01

    Mild derangements of acid-base status are common features in peritoneal dialysis patients, metabolic acidosis being the most frequent alteration. One of the main tasks of dialysis is to correct these derangements and the target is the normalization of the acid-base parameters since they affect several organs and functions. Since factors affecting acid-base homeostasis are intrinsic characteristics of the individual patient (metabolic acid production, distribution space for bicarbonate, dialytic prescription, etc.), it is not surprising that only relatively few patients achieve the normal range. Only a certain modulation of buffer infusion by using different buffer concentrations in the dialysis fluid may ensure a good correction in a large percentage of patients.

    This article reports the treatment with continuous ambulatory peritoneal dialysis of a patient with intractable congestive heart failure secondary to an ischemic cardiomyopathy. Although the use of peritoneal dialysis to treat refractory heart failure is not new, the advent of an effective continuous peritoneal dialysis system has allowed its use over prolonged periods of time. The two-year treatment interval described herein represents the longest reported application of this technique, to the best of our knowledge.

    Can we identify modifiable risk factors for peritonitis in patients undergoing peritoneal dialysis (PD)? We aimed to determine whether housing standard, PD exchange technique or patient motivation might be modifiable risks for peritonitis. We also explored the relationship between lack of motivation and depression. Nurse home visits assessed PD exchange technique, environment and patient motivation. Motivation scores were correlated separately with an Apathy Evaluation Score and a depression score using PHQ-9 questionnaires. Home hygiene, exchange technique and motivation were above average in 53%, 56% and 60%, respectively in 104 patients undergoing PD. After 15 months, 25.9% patients developed peritonitis but nurses' ratings of homes and exchange techniques were not predictive. Low patient motivation was predictive. Patients rated to have above or below median motivation had significantly different Apathy Scores (p = 0.0002). Unmotivated depressed patients were significantly more likely to develop peritonitis compared to motivated depressed patients. Lack of motivation predicted peritonitis particularly if associated with depression. Further studies are required focusing on specific motivation scoring schemes and the psychosocial support that might lead to better outcomes. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

    Summary Background and objectives The effect of biocompatible peritoneal dialysis (PD) solutions on PD-related peritonitis is unclear. This study sought to evaluate the relationship between use of biocompatible solutions and the probability of occurrence or clinical outcomes of peritonitis. Design, setting, participants, & measurements The study included all incident Australian patients receiving PD between January 1, 2007, and December 31, 2010, using Australia and New Zealand Dialysis and Transplant Registry data. All multicompartment PD solutions of neutral pH were categorized as biocompatible solutions. The independent predictors of peritonitis and the use of biocompatible solutions were determined by multivariable, multilevel mixed-effects Poisson and logistic regression analysis, respectively. Sensitivity analyses, including propensity score matching, were performed. Results Use of biocompatible solutions gradually declined (from 7.5% in 2007 to 4.2% in 2010), with preferential use among smaller units and among younger patients without diabetes mellitus. Treatment with biocompatible solution was associated with significantly greater overall rate of peritonitis (0.67 versus 0.47 episode per patient-year; incidence rate ratio, 1.49; 95% confidence interval [CI], 1.19 to 1.89) and with shorter time to first peritonitis (hazard ratio [HR], 1.48; 95% CI, 1.17 to 1.87), a finding replicated in propensity score–matched cohorts (HR, 1.36; 95% CI, 1.09 to 1.71). Conclusions In an observational registry study, use of biocompatible PD solutions was associated with higher overall peritonitis rates and shorter time to first peritonitis. Further randomized studies adequately powered for a primary peritonitis outcome are warranted. PMID:23949232

    Peritoneal dialysis, the preferred long-term renal replacement modality in the pediatric population, can also be used during the post transplant period. Although it is well known that peritonitis or other complications may occur related to the peritoneal dialysis catheter, less is known about complications related to the peritoneal dialysis during the posttransplant period. Our objective was to evaluate the complications related to use of a peritoneal dialysis catheter during the posttransplant period and to determine the optimum time for removal of the peritoneal dialysis catheter. We retrospectively analyzed 33 chronic peritoneal dialysis patients. Pretransplant and posttransplant demographics and clinical and laboratory data for each patient were recorded, including incidence of peritonitis and incidence of peritoneal dialysis catheter requirement after transplant. Mean age of patients at transplant was 12.8 ± 4.0 years (range, 3.5-18.0 y). Mean catheter removal time was 81.1 ± 36.2 days (range, 22.0-152.0 d). The peritoneal dialysis catheter was used in 6 of 33 patients (18.2%); none of these patients developed peritonitis. In contrast, 2 of the 27 patients who did not use the peritoneal dialysis catheter developed peritonitis. Our data suggest that the need for catheter use occurs predominantly during the first month, and infectious complications usually happen later. Previously, the trend was to not remove the peritoneal dialysis catheter at the time of transplant. However, in light of recent literature and our present study, we recommend that the time of catheter removal should be modified and decided for each patient on an individual basis.

  16. Peritoneal dialysis associated infections: An update on diagnosis and management

    Peritoneal dialysis (PD) is associated with a high risk of infection of the peritoneum, subcutaneous tunnel and catheter exit site. Although quality standards demand an infection rate < 0.67 episodes/patient/year on dialysis, the reported overall rate of PD associated infection is 0.24-1.66 episodes/patient/year. It is estimated that for every 0.5-per-year increase in peritonitis rate, the risk of death increases by 4% and 18% of the episodes resulted in removal of the PD catheter and 3.5% resulted in death. Improved diagnosis, increased awareness of causative agents in addition to other measures will facilitate prompt management of PD associated infection and salvage of PD modality. The aims of this review are to determine the magnitude of the infection problem, identify possible risk factors and provide an update on the diagnosis and management of PD associated infection. Gram-positive cocci such as Staphylococcus epidermidis, other coagulase negative staphylococcoci, and Staphylococcus aureus (S. aureus) are the most frequent aetiological agents of PD-associated peritonitis worldwide. Empiric antibiotic therapy must cover both gram-positive and gram-negative organisms. However, use of systemic vancomycin and ciprofloxacin administration for example, is a simple and efficient first-line protocol antibiotic therapy for PD peritonitis - success rate of 77%. However, for fungal PD peritonitis, it is now standard practice to remove PD catheters in addition to antifungal treatment for a minimum of 3 wk and subsequent transfer to hemodialysis. To prevent PD associated infections, prophylactic antibiotic administration before catheter placement, adequate patient training, exit-site care, and treatment for S. aureus nasal carriage should be employed. Mupirocin treatment can reduce the risk of exit site infection by 46% but it cannot decrease the risk of peritonitis due to all organisms. PMID:24175248

    Peritoneal equilibration test (PET) employing a 2.27%/2.5% glucose exchange is the most widely used method of to evaluating peritoneal function and small solute transport. Hypertonic (3.86%/4.25% glucose) PET has been recently recommended for the evaluation of ultrafiltration and to study certain causes of ultrafiltration failure, such as aquaporin dysfunction, through the analysis of dialysate sodium. However, there is not enough information on the optimal way to express the changes in dialysate sodium concentration, the normal range of values for this parameter, and possible adverse effects of hypertonic PET in the general population of peritoneal dialysis patients. A hypertonic PET was performed in 22 patients. Ultrafiltration failure (ultrafiltration < 0.4 L) was present in seven patients. Patients with ultrafiltration failure had higher small solute peritoneal transport and dialysate sodium concentration and had been treated with peritoneal dialysis for longer periods of time. Dialysate sodium concentration at 60 and 240 minutes was directly correlated with small solute peritoneal transport calculated as D/PCr240 (r = 0.74, p = 0.0008 y r = 0.84, p < 0.0001) and inversely correlated with ultrafiltration (r = 0.64, p = 0.0016 y r = 0.72, p = 0.0002). An absence of a dip in dialysis sodium, suggestive of aquaporin dysfunction, was only observed in one patient with a high-average small solute peritoneal transport. Dialysate sodium concentration at 60 minutes is a better discriminator between ultrafiltration failure patients than parameters such as D/PNa or the absolute dip in dialysate sodium with respect to time zero. We observed the following adverse effects: symptomatic hypotension in 2 patients with preserved ultrafiltration. In conclusion, hypertonic PET allows to confirm the diagnosis of ultrafiltration failure, but monitoring dialysate sodium concentration offers additional information only in patients with severe aquaporin dysfunction. Hypertonic PET may

    Background Tuberculosis continues to be an important health problem in the world. Besides pulmonary involvement extrapulmonary involvement becomes an affair in developing countries, even in developed countries. Case presentation A thirty-six year old male patient was admitted with abdominal pain, diarrhea, nausea, vomiting and fever which had started one week before. The patient had been followed up with predialisis Chronic Renal Failure(CRF) diagnosis for 4 years and receiving continuous ambulatory peritoneal dialysis (CAPD) treatment for 4 months. In peritoneal fluid, 1600/mm3 cells were detected and 70% of them were polymorphonuclear leukocytosis. The patient begun nonspesific antibiotherapy but no benefit was obtained after 12 days and peritoneal fluid bacterial cultures remained negative. Peritoneal smear was positive for Asid-fast basilli (AFB), and antituberculosis therapy was started with isoniazid, rifampicine, ethambutol and pyrazinamide. After 15 days his peritoneal fluid cell count was decreased and his symptoms were relieved. Peritoneal fluid tuberculosis culture was found positive. Conclusion Considering this case, we think that in patients with CAPD catheter and peritonitis; when peritoneal fluid leukocytes are high and PMNL are dominant, AFB and tuberculosis culture must be investigated besides bacterial culture routinely.

    Incremental dialysis consists in prescribing a dialysis dose aimed towards maintaining total solute clearance (renal + dialysis) near the targets set by guidelines. Incremental peritoneal dialysis (incrPD) is defined as one or two dwell-times per day on CAPD, whereas standard peritoneal dialysis (stPD) consists in three-four dwell-times per day. Single-centre cohort study. Enrollement period: January 2002-December 2007; end of follow up (FU): December 2012. incident patients with FU ≥6 months, initial residual renal function (RRF) 3-10 ml/min/1.73 sqm BSA, renal indication for PD. Median incrPD duration was 17 months (I-III Q: 10; 30). There were no statistically significant differences between 29 patients on incrPD and 76 on stPD regarding: clinical, demographic and anthropometric characteristics at the beginning of treatment, adequacy indices, peritonitis-free survival (peritonitis incidence: 1/135 months-patients in incrPD vs. 1/52 months-patients in stPD) and patient survival. During the first 6 months, RRF remained stable in incrPD (6.20 ± 2.02 vs. 6.08 ± 1.47 ml/min/1.73 sqm BSA; p = 0.792) whereas it decreased in stPD (4.48 ± 2.12 vs. 5.61 ± 1.49; p < 0.001). Patient survival was affected negatively by ischemic cardiopathy (HR: 4.269; p < 0.001), peripheral and cerebral vascular disease (H2.842; p = 0.006) and cirrhosis (2.982; p = 0.032) and positively by urine output (0.392; p = 0.034). Hospitalization rates were significantly lower in incrPD (p = 0.021). Eight of 29 incrPD patients were transplanted before reaching full dose treatment. IncrPD is a safe modality to start PD; compared to stPD, it shows similar survival rates, significantly less hospitalization, a trend towards lower peritonitis incidence and slower reduction of renal function.

    It is well known that bioincompatible peritoneal dialysate plays a central role in the development of peritoneal fibrosis. Peritoneal inflammation continues even after the cessation of peritoneal dialysate stimulation. It is important to establish the definition of persistent inflammation in the peritoneal cavity at the cessation of peritoneal dialysis (PD). The objective of the present study was to determine whether pentraxin 3 (PTX3) in peritoneal effluent (PE) may be a new biomarker in PD patients. Serum, PE, and peritoneal specimens were obtained from 50 patients with end-stage kidney disease at Juntendo University Hospital. Samples of 19 patients were obtained at the initiation of PD and those of 31 patients at the cessation of PD. PTX3, high-sensitivity CRP, and MMP-2 and IL-6 were analyzed. An immunohistological examination using an anti-PTX3 antibody was performed. Expressions of PTX3 were observed in endothelial cells, fibroblasts, and mesothelial cells in the peritoneum. The PTX3 level in PE at the cessation of PD was significantly higher than that at the initiation of PD. Effluent PTX3 levels in patients with a history of peritonitis or a PD duration of more than 8 years were significantly higher than those in patients without peritonitis or patients with a PD duration of <8 years. The PTX3 level was significantly correlated with MMP-2 and IL-6 levels in PE, as well as the thickness of the submesothelial compact zone and the vasculopathy. It appears that PTX3 may be a new biomarker of peritoneal inflammation and progressive fibrosis.

    Nocardia asteroides is a rare pathogen in peritoneal dialysis-related peritonitis. We report on a 13-year-old female with Nocardia asteroides peritonitis complicated by an intra-abdominal abscess. Linezolid was administered intravenously for 3 months and followed by oral therapy for an additional 5 months with close monitoring for adverse effects. The patient was discharged after 3 months of hospitalization on hemodialysis. The diagnosis and management of such cases can be problematic due to the slow growth and difficulty of identifying Nocardia species. The optimal duration of treatment for Nocardia peritonitis is not known. Linezolid can be used for prolonged periods in cases of trimethoprim/sulfamethoxazole-resistant cases with close monitoring for adverse effects.

    The share of peritoneal dialysis (PD) in the spectrum of chronic dialysis has decreased markedly in the Netherlands in the last 15 years. Consequently, the knowledge of nephrologists and nursing staff on PD has declined leading to a negative spiral in which loss of experience resulted in loss of enthusiasm to offer PD to patients and also in less interest in the new PD developments. All these changes took place while the results of PD improved and patient survival was at least similar to that on haemodialysis. The aim of this review is first to give a summary of the principles and practice of patient and staff education and to describe the role of the medical contribution in decision-making. On this basis, the second aim is to update internist-nephrologists on a number of issues that have been underexposed in the past. Recent patient and technique survival data of PD patients is reviewed, and also the new insights into dialysis adequacy. The presence of residual renal function is the main determinant of patient survival together with prevention of overhydration. Urea and creatinine removal are not important at all when patients are still passing urine. Many early problems with PD are due to the peritoneal catheter and suggestions are made for improvement of its function. The prevention and management of infections is reviewed, and also the regular assessment of peritoneal function. Free water transport is a predictor of encapsulating peritoneal sclerosis (EPS), which should be assessed regularly. The pathogenesis of EPS, treatment and the decreasing incidence are discussed.

    Very young children with chronic kidney disease often have difficulty maintaining adequate nutrition, which contributes to the high prevalence of short stature in this population. Characteristics of the dialysis prescription and supplemental feeding via a nasogastric (NG) tube or gastrostomy may improve growth, but this is not well understood. Here, we analyzed data from 153 children in 18 countries who commenced chronic peritoneal dialysis at <24 months of age. From diagnosis to last observation, 57 patients were fed on demand, 54 by NG tube, and 10 by gastrostomy; 26 switched from NG to gastrostomy; and 6 returned from NG to demand feeding. North American and European centers accounted for nearly all feeding by gastrostomy. Standardized body mass index (BMI) uniformly decreased during periods of demand feeding and increased during NG and gastrostomy feeding. Changes in BMI demonstrated significant regional variation: 26% of North American children were obese and 50% of Turkish children were malnourished at last observation (P < 0.005). Body length decreased sharply during the first 6 to 12 months of life and then tended to stabilize. Time fed by gastrostomy significantly associated with higher lengths over time (P < 0.001), but adjustment for baseline length attenuated this effect. In addition, the use of biocompatible peritoneal dialysate and administration of growth hormone independently associated with improved length, even after adjusting for regional factors. In summary, growth and nutritional status vary regionally in very young children treated with chronic peritoneal dialysis. The use of gastrostomy feeding, biocompatible dialysis fluid, and growth hormone therapy associate with improved linear growth. PMID:22021715

    Peritoneal dialysis (PD) limitation as renal replacement therapy is mostly due to peritonitis and complications. Formation and persistence of intra-abdominal loculations is often under-diagnosed. Encapsulated peritoneal sclerosis (EPS) is a life-threatening complication, but malnutrition, recurrent peritonitis and early membrane failure are insidious enemies that need to be emphasized. It is important to highlight the persistence of intra-abdominal fluid collection after clinical resolution of peritonitis in PD patients and to indicate a new medical management approach for an early diagnosis. During five years, we selected PD peritonitis cases followed by a six months interval free of infections. Ninety-seven subjects were followed at six months and one year after the first peritonitis. Tomography had been performed to patients presenting a positive inflammatory state without a specific infectious cause. Subjects presenting documented localized fluid collection (31 cases) were divided into: drug-treated group and those undergoing laparoscopy by a new surgery technique (seven patients); a comparison regarding the clinical state and biohumoral parameters was assessed in both groups. The prevalence of intra-abdominal loculation following an apparent resolved peritonitis was high (31.9%). The cases undergoing laparoscopy presented a better evolution - improved clinical status (p=0.001), higher hemoglobin values (p=0.06), significant lower doses of erythropoietin requirement (p=0.03), improved dialysis adequacy (p=0.005) and inflammatory state. In cases with confirmed fluid encapsulated loculation, an active attitude (screening imaging protocol and laparoscopic exploration) appears to be mandatory, decreasing the risk of EPS, a serious complication which pathology and treatment are incompletely understood.

    In the present study, we identified patients who had difficulties learning the minimum knowledge and skills required to carry out peritoneal dialysis (PD), and we compared the outcomes in this subgroup of patients with outcomes in the general PD population. We calculated the mean learning sessions needed by our total PD population during the training period. We then assigned patients to one of two groups according to the number of learning sessions they needed. Patients who required a number of sessions equal to or less than the mean were placed in the "standard learning" group; patients who required more sessions but who reached the minimum knowledge and skills were placed in the "learning difficulties " group. We compared these two groups in terms of age, sex, diabetes status, autonomy to perform PD, family support, education level, residual renal function, and Charlson comorbidity index. Outcomes on PD included time to first peritonitis episode, peritonitis rate, percentage of patients free of peritonitis during follow-up, survival time on PD, and transfer to hemodialysis. Patients with learning difficulties were older and had more comorbidities. Outcomes on PD in the learning difficulties group were similar to those in the standard learning group, except for time to first peritonitis.

    Chronic inflammatory conditions during peritoneal dialysis (PD)-treatment lead to the impairment of peritoneal tissue integrity. The resulting structural and functional reorganization of the peritoneal membrane diminishes ultrafiltration rate and thereby enhances mortality by limiting dialysis effectiveness over time. Tumour necrosis factor (TNF) and its receptors TNFR1 and TNFR2 are key players during inflammatory processes. To date, the role of TNFR1 in peritoneal tissue damage during PD-treatment is completely undefined. In this study, we used an acute PD-mouse model to investigate the role of TNFR1 on structural and morphological changes of the peritoneal membrane. TNFR1-mediated TNF signalling in transgenic mice expressing human TNFR1 was specifically blocked by applying a monoclonal antibody (H398) highly selective for human TNFR1 prior to PD-treatment. Cancer antigen-125 (CA125) plasma concentrations were measured by enzyme-linked immunosorbent assay (ELISA). Western blot analyses were applied to determine TNFR2 protein concentrations. Histological staining of peritoneal tissue sections was performed to assess granulocytes within the peritoneal membrane as well as the content of hyaluronic acid and collagen. We show for the first time that the number of granulocytes within the peritoneal membrane is significantly reduced in mice pre-treated with H398. Moreover, we demonstrate that blocking of TNFR1 not only influences CA125 values but also hyaluronic acid and collagen contents of the peritoneal tissue in these mice. These results strongly suggest that TNFR1 inhibition attenuates peritoneal damage caused by peritoneal dialysis fluid (PDF) and therefore may represent a new therapeutic approach in the treatment of PD-related side effects.

    Conventional low biocompatibility peritoneal dialysis (PD) fluid composition has been driven by manufacturing expediency and cost limitations. PD is associated with significant acute changes in cardiovascular functional parameters, at least in part influenced by fluid composition. Short-term control of blood pressure (BP) is under control of the baroreflex arc. The aim of this study was to investigate the effects of PD fluid biocompatibility on baroreflex sensitivity (BRS). We studied 10 non-diabetic established continuous ambulatory PD patients, in a randomized crossover trial comparing conventional and biocompatible PD fluids. Systemic hemodynamics were continuously monitored using digital pulse-wave analysis. Plasma glucose and insulin were assessed during treatment with both 1.36% and 3.86% glucose-containing fluids. BRS was calculated offline from continuous BP and interbeat interval data. BRS was significantly higher with conventional PD fluid during both 1.36% (P<0.001) and 3.86% (P<0.001) dwells. Systolic BP was higher; heart rate, stroke volume, and cardiac output were lower; and total peripheral resistance increased during exposure to either fluid. There were significant differences between fluids with respect to the magnitude of these responses. Plasma glucose and insulin concentrations, and ultrafiltration volumes were significantly higher during the 3.86% dwell than the 1.36% dwell, but there were no differences between standard and biocompatible fluids. We have demonstrated for the first time that PD fluid biocompatibility rapidly affects BRS. These changes occur against a background of cardiovascular variability, hyperinsulinemia, and hyperglycemia. Further research is needed to explore the mechanism and, more importantly, the consequences of these findings.

    Background Infectious peritonitis (IP) is the most common complication in peritoneal dialysis (PD). The purpose of this study is to assess the prevalence of IP and to determine its clinical, biological, and evolutive characteristics. Patients and methods We conducted a five year, five months retrospective study from July 2006 to December 2011. All patients on peritoneal dialysis that have been followed on PD for a minimum of 3 months and who presented IP during follow-up were included. Data were analyzed using SPSS 17.0. Results The 76 episodes of IP were identified in 36 patients. The peritonitis rate (months × patients/peritonitis), as calculated by the Registre de Dialyse Péritonéale de Langue Française (RDPLF Registry) [French peritoneal dialysis registry] in December 2011, was 18.59. Time to occurrence of peritonitis from the start of peritoneal exchange was 15.44±10 months. The mean age of our patients was 49.1±16.8 years [10–80]: the youngest patient’s age was 10, while the oldest was 80 years old (male to female: sex ratio M/F=1,66). Also, 22% of our patients were diabetic. The mean follow-up in PD was 22.6±14 months. Abdominal pain was present in 79% of the cases. Fever and vomiting were noted in 42% and 38% of cases, respectively. The C-reactive protein rate was elevated in 77% of cases, and leukocytosis was found in 27% of cases. Bacteriological proof was present in 73.68% of cases. Gram-positive cocci were involved in 56.6% of microbiologically proven IP cases. Gram-negative bacilli were represented in 37.7%. The outcome was favorable in 89.4%. The PD catheter was removed in 2.63% of the cases. In addition, 7.89% of our patients were transferred to hemodialysis. Discussion The rate of IP remains high in our series. More than one-half of the peritonitis cases with positive cultures (56.6%) were caused by Gram-positive cocci. Gram-negative bacilli ranked second (27.7%). These results agree with data in the literature. Moreover, the rate of

    There is limited available evidence regarding the role of monitoring serum vancomycin concentrations during treatment of peritoneal dialysis (PD)-associated peritonitis. A total of 150 PD patients experiencing 256 episodes of either gram-positive or culture-negative peritonitis were included to investigate the relationship between measured serum vancomycin within the first week and clinical outcomes of cure, relapse, repeat or recurrence of peritonitis, catheter removal, temporary or permanent transfer to hemodialysis, hospitalization and death. Vancomycin was used as an initial empiric antibiotic in 54 gram-positive or culture-negative peritonitis episodes among 34 patients. The median number of serum vancomycin level measurements in the first week was 3 (interquartile range; IQR 1 - 4). The mean day-2 vancomycin level, measured in 34 (63%) episodes, was 17.5 ± 5.2 mg/L. Hospitalized patients were more likely to have serum vancomycin levels measured on day 2 and ≥ 3 measurements in the first week. The peritonitis cure rates were similar between patients with < 3 and ≥ 3 measurements in the first week (77% vs 57%, p = 0.12) and if day-2 vancomycin levels were measured or not (68% vs 65%, p = 0.84). The average day-2 (18.0 ± 5.9 vs 16.6 ± 3.2, p = 0.5), first-week average (18.6 ± 5.1 vs 18.6 ± 4.3, p = 0.9) and nadir (14.5 ± 4.1 vs 13.6 ± 4.2, p = 0.5) vancomycin levels were comparable in patients who did or did not achieve peritonitis cure. Similar results were observed for all other clinical outcomes. The clinical outcomes of gram-positive and culture-negative peritonitis episodes are not associated with either the frequency or levels of serum vancomycin measurements in the first week of treatment when vancomycin is dosed according to International Society for Peritoneal Dialysis (ISPD) Guidelines.

    Loss of peritoneal function due to peritoneal fibrosing syndrome (PFS) is a major factor leading to treatment failure in chronic peritoneal dialysis (PD) patients. Although the precise biologic mechanisms responsible for these changes have not been defined, the general assumption is that alterations in peritoneal function are related to structural changes in the peritoneal membrane. Studies of the peritoneal membrane by non-invasive ultrasonography (US) in chronic PD patients are limited. The aim of the present study is to assess the relationship between functional parameters of peritoneum and peritoneal thickness measured by US in children treated by chronic PD. We recruited two groups of patients: 23 subjects (13 females, 10 males) on chronic PD (patient group) and 26 (7 females, 19 males) on predialysis out-patient follow-up (creatinine clearance: 20-60 mL/min/1.73 m(2)) (control group). Age, sex, weight, height, body mass index (BMI), chronic PD duration, episodes of peritonitis and the results of peritoneal equilibration test (PET) were recorded. Hemoglobin (Hb), blood pressure (BP), left ventricular mass index (LVMI) and renal osteodystrophy (ROD) parameters were also obtained. The thickness of the parietal peritoneum was measured by trans-abdominal US in all children. Statistical analyses were performed by using Student's t and Pearson's correlation tests. Mean peritoneal thickness in chronic PD patients (1028.26 ± 157.26 μm) was significantly higher than control patients (786.52 ± 132.33). Mean peritoneal thickness was significantly correlated with mean body height (R(2) = 0.93, p < 0.05), BMI (R(2) = 0.25, p < 0.05), chronic PD duration (R(2) = 0.64, p < 0.05), episodes of peritonitis (R(2) = 0.93, p < 0.05), D/Pcreatinine (R(2) = 0.76, p < 0.05) and D4/D0glucose (R(2) = 0.81, p < 0.05). No correlation was found between peritoneal thickness and Hb, BP, LVMI and ROD parameters. In conclusion

    The main objective of the study was to analyse the progression of residual renal function according to the dialysis technique (peritoneal dialysis or haemodialysis) and the frequency of treatment (two or three sessions of haemodialysis per week). As secondary objectives, we studied the progression of the serum concentration levels of β2 microglobulin and the response of anaemia to erythropoietic agents. 193 non-anuric patients were included and began renal replacement therapy with dialysis in our hospital between 1 January 2006 and 31 December 2011, with a follow-up period of over three months. 61 patients (32%) began treatment with two haemodialysis sessions per week, 49 patients (25%) with three haemodialysis sessions per week and 83 patients (43%) with peritoneal dialysis. The glomerular filtration rate was measured as the mean of the renal clearances of urea and creatinine. The rate of decrease in glomerular filtration was the same in patients who began treatment with two haemodialysis sessions per week and with peritoneal dialysis (median 0.18 ml/min/month) and it was higher in patients who began treatment with three sessions of haemodialysis per week (median 0.33 ml/min/month, P<.05). Throughout progression, the glomerular filtration rate did not display differences between the group that began with two weekly sessions of haemodialysis and the group on peritoneal dialysis, and it was lower in the group that began treatment with three sessions of haemodialysis per week with statistical significance during the first 24 months of follow up. In the three patient groups, β2-microglobulin concentration increased as the glomerular filtration rate decreased and it was higher in the group on three weekly haemodialysis sessions for the first 12 months of follow up. In all the controls carried out, there was a negative correlation between the beta-2 microglobulin concentration and the glomerular filtration rate (P<.001). The erythropoietin dose was negatively related

    An evaluation of the characteristics of peritoneal solute and water transport is essential to assess the suitability of prescribing dialysis in patients suffering from chronic renal disease. There are currently a series of models to perform this evaluation. The peritoneal equilibration test (PET) evaluates the peritoneal transport capacity, classifying the patients into four transport categories: high, high-average, low-average, and low. The short PET enables the same evaluation to be made in only 2hours, and has been validated in paediatric patients. On the other hand, the MiniPET provides additional information by evaluating the free water transport capacity by the ultra-small pores, and the Accelerated Peritoneal Examination Time (APEX) evaluates the time when the glucose and urea equilibration curves cross, and has been proposed as the optimum dwell time to achieve adequate ultrafiltration. An analysis is presented on the current information on these diagnostic methods as regards free water transport via aquaporins, which could be an important tool in optimising solute and water transport in patients on chronic peritoneal dialysis, particularly as regards the cardiovascular prognosis.

    Peritonitis is a debilitating infectious complication of peritoneal dialysis (PD). Drug-resistant bacterial peritonitis typically has a lower response rate to antibiotics. In the past 15 years, newer antibiotics with activities against drug-resistant Gram-positive bacteria have been developed. In most circumstances, peritonitis due to methicillin-resistant staphylococci responds to vancomycin. If vancomycin cannot be used due to allergy and/or non-susceptibility, there is increasing evidence that linezolid and daptomycin are the drugs of choice. It is reasonable to start linezolid orally or intravenously, but subsequent dose reduction may be necessary in case of myelosuppression. Daptomycin can be given intravenously or intraperitoneally and has excellent anti-biofilm activity. Other treatment options for drug-resistant Gram-positive bacterial peritonitis include teicoplanin, tigecycline and quinupristin/dalfopristin. Teicoplanin is not available in some countries (e.g. the USA). Tigecycline can only be given intravenously. Quinupristin/dalfopristin is ineffective against Enterococcus faecalis and there is only low-quality evidence to support its efficacy in the treatment of peritonitis. Effective newer antibiotics against drug-resistant Gram-negative bacteria are lacking. Polymyxins can be considered, but evidence on its efficacy is limited. In this review, we will discuss the potential use of newer antibiotics in the treatment of drug-resistant bacterial peritonitis in PD patients. PMID:27478608

    Mesothelial-to-mesenchymal transition (MMT) is an auto-regulated physiological process of tissue repair that in uncontrolled conditions such as peritoneal dialysis (PD) can lead to peritoneal fibrosis. The maximum expression of peritoneal fibrosis induced by PD fluids and other peritoneal processes is the encapsulating peritoneal sclerosis (EPS) for which no specific treatment exists. Tamoxifen, a synthetic estrogen, has successfully been used to treat retroperitoneal fibrosis and EPS associated with PD. Hence, we used in vitro and animal model approaches to evaluate the efficacy of Tamoxifen to inhibit the MMT as a trigger of peritoneal fibrosis. In vitro studies were carried out using omentum-derived mesothelial cells (MCs) and effluent-derived MCs. Tamoxifen blocked the MMT induced by transforming growth factor (TGF)-β1, as it preserved the expression of E-cadherin and reduced the expression of mesenchymal-associated molecules such as snail, fibronectin, collagen-I, α-smooth muscle actin, and matrix metalloproteinse-2. Tamoxifen-treatment preserved the fibrinolytic capacity of MCs treated with TGF-β1 and decreased their migration capacity. Tamoxifen did not reverse the MMT of non-epitheliod MCs from effluents, but it reduced the expression of some mesenchymal molecules. In mice PD model, we demonstrated that MMT progressed in parallel with peritoneal membrane thickness. In addition, we observed that Tamoxifen significantly reduced peritoneal thickness, angiogenesis, invasion of the compact zone by mesenchymal MCs and improved peritoneal function. Tamoxifen also reduced the effluent levels of vascular endothelial growth factor and leptin. These results demonstrate that Tamoxifen is a therapeutic option to treat peritoneal fibrosis, and that its protective effect is mediated via modulation of the MMT process. PMID:23637793

    Background/Aims. Peritoneal dialysis is a successful renal replacement therapy (RRT) for old and dependent patients. We evaluated the clinical outcomes of an assisted peritoneal dialysis (aPD) program developed in a Portuguese center. Methods. Retrospective study based on 200 adult incident patients admitted during ten years to a PD program. We included all 17 patients who were under aPD and analysed various parameters, including complications with the technique, hospitalizations, and patient and technique survival. Results. The global peritonitis rate was lower in helped than in nonhelped patients: 0.4 versus 0.59 episodes/patient/year. The global hospitalization rate was higher in helped than in nonhelped patients: 0.67 versus 0.45 episodes/patient/year (p = NS). Technique survival in helped patients versus nonhelped patients was 92.3%, 92.3%, 83.1%, and 72.7% versus 91.9%, 81.7%, and 72.1%, and 68.3%, at 1, 2, 3, and 4 years, respectively (p = NS), and patient survival in helped patients versus nonhelped patients was 93.3%, 93.3%, 93.3%, and 74.7% versus 95.9% 93.7%, 89%, and 82% at 1, 2, 3, and 4 years, respectively (p = NS). Conclusions. aPD offers an opportune, reliable, and effective home care alternative for patients with no other RRT options. PMID:26600950

    Handheld glucose meters remain a rapid means of excluding hypoglycemia as a cause of altered mental status in the Emergency Department. However, emergency physicians must be alert for factors that can mask hypoglycemia at the bedside. An 80-year-old man with diabetes mellitus and end-stage renal disease on peritoneal dialysis presents with altered mental status, hypotension, and a bedside handheld glucose meter reading of 99mg/dL. His mental status failed to improve with treatment of hypotension and the patient was intubated for airway protection. Laboratory-measured serum glucose was 29mg/dL. His mental status improved after glucose administration. It was subsequently determined that the patient used icodextrin (Extraneal(®), Baxter Healthcare Corporation, Deerfield, IL) as his peritoneal dialysate. This is partly absorbed into serum and hydrolyzed to oligosaccharides that are falsely detected as glucose by many handheld glucose meters. The peritoneal dialysate icodextrin can produce falsely elevated bedside glucose meter values. As the prevalence of diabetic nephropathy and dialysis increases, emergency physicians must remain vigilant for such cases of unrecognized hypoglycemia. Copyright © 2013 Elsevier Inc.

  17. Peritoneal dialysis: how we can achieve improvement of PD penetration.

    PubMed

    Peritoneal dialysis (PD) is a well established renal replacement therapy (RRT). It appears to have some excellent properties as a first line RRT, as it preserves residual renal function, improves clearance of middle and larger solutes and preserves vascular access. To improve PD penetration, it is necessary to have a well established pre-dialysis programme, as information seems to be the clue in the choice and the success of PD. Furthermore, it is important that patients and nurses are well educated in the practice of PD. This reduces the need for hypertonic bags by better compliance with the salt restrictive diet, reduces exposure to dialysate per se by adapting the number and length of the dwells to the needs of the patient, and increases peritonitis-free survival, thus prolonging the survival of the peritoneal membrane. In addition, it is clear that the use of new low glucose degradation products and normal pH solutions will also improve the technical success of PD. The collaboration of industry with local health care providers could be a necessity in overcoming the costs induced by the import of dialysate solutions paid for in foreign currency.

    The increasing prevalence of chronic illnesses and kidney disease, in particular, makes it necessary to adopt new approaches towards their management (Wagner, 1998). Evidence suggests that promoting self-management improves the health status of peritoneal dialysis (PD) patients, as they manage upwards of 90% of their own care. Patients who are unable to self-manage suffer from various complications. This project proposes an intervention aimed at improving self-management skills among PD patients. To promote self-management in peritoneal dialysis patients. This is achieved through the following objectives: (a) develop an algorithm that can improve patients' ability to solve the specific problem of fluid balance maintenance, (b) develop an educational session for patients on how to use the algorithm, and (c) develop an implementation strategy in collaboration with the PD nurse. Three measures evaluate the effectiveness of the intervention. First, a telephone call log shows that participating patients call the clinic less to inquire about fluid balance maintenance. Next, a pre- and post-intervention knowledge test measures definite knowledge increase. Finally, a Patient Satisfaction Questionnaire reveals overall satisfaction with the intervention. This project, which proved beneficial to our patient population, could be duplicated in other clinics. The algorithm "How do I choose a dialysis bag" and the slides of the educational sessions can be shared with PD nurses across the country for the benefit of PD patients.

    Compared with hemodialysis, peritoneal dialysis (PD) is a cost-effective and patient-centered option with an early survival advantage, yet only 7% of patients with end-stage renal disease in the United States receive PD. PD underutilization is due in part to nephrologists' unfamiliarity with directly starting PD in patients who present with kidney failure requiring urgent initiation of dialysis. Quality improvement report. Single-center study whereby 18 patients who presented urgently with chronic kidney disease stage 5 without a plan for dialysis modality were offered PD as the initial modality of dialysis. Concurrently, 9 patients started on PD therapy nonurgently were included as the comparative group. An urgent-start PD program was developed to support and standardize the process by which patients without a plan for dialysis modality were started on PD. This included rapid PD access placement, PD nursing education, and administrative support. Standardized protocols were created for modality selection, initial prescription, and prevention and management of complications. Short-term (90-day) clinical outcomes (Kt/V, hemoglobin, iron saturation, parathyroid hormone, phosphorus, calcium, and albumin) and complications (peritonitis, exit-site infections, leaks, and catheter malfunction) were compared between the urgent-start and non-urgent-start PD groups. Short-term clinical outcomes were similar between the 2 groups for all parameters except uncorrected serum calcium level, which was lower in the urgent-start group (P = 0.02). Peritonitis, exit-site infection, catheter-related complications, and other complications were similar between the 2 groups, although the number of minor leaks was higher in the urgent-start group. This is a single-center nonrandomized study with a small sample size. Our structured program shows safety and feasibility in starting PD in patients with kidney failure who present without a plan for dialysis modality. The steps laid out in this

    Anterior ischemic optic neuropathy (AION) is characterized by infarction of the optic nerve head due to hypoperfusion of the posterior ciliary arteries and causes sudden blindness in adults on chronic dialysis, but has rarely been described in children. Unlike adults, children do not have comorbidities related to aging. We retrospectively analyzed data of 7 children on nocturnal continuous cycling peritoneal dialysis (CCPD) who developed AION identified within the Italian Registry of Pediatric Chronic Dialysis. We also summarized data from 10 cases reported in the literature. Our 7 patients suffered from acute onset bilateral blindness. Their mean age was 3.2 years and chronic hypotension had been observed prior the AION in 3 of the 7 children. Low systolic blood pressure (SBP) was associated with higher risk of developing AION according to statistical analysis. None recovered completely. In total, 11 out of 16 experienced a partial recovery and no clear evidence emerged favoring specific treatments. Hypotensive children treated with CCPD are at increased risk of developing AION, which often results in irreversible blindness. Copyright © 2015 International Society for Peritoneal Dialysis.

    Chronic inflammation of the peritoneum causes peritoneal injury in patients on peritoneal dialysis. Intercellular adhesion molecule-1 and its circulating form, soluble intercellular adhesion molecule-1, play pivotal roles in inflammation. However, their role in peritoneal injury is unclear. We measured changes in intercellular adhesion molecule-1 expression in the peritoneum of a peritoneal injury model in rats. The associations between soluble intercellular adhesion molecule-1 levels in drained dialysate and the solute transport rate (D/P-Cr and D/D0-glucose) determined by the peritoneal equilibration test, and matrix metalloproteinase-2 levels in drained dialysate were investigated in 94 peritoneal drained dialysate samples. Intercellular adhesion molecule-1 expression was increased in the peritoneum of rats with peritoneal injury. Soluble intercellular adhesion molecule-1 levels in drained dialysate were significantly positively correlated with D/P-Cr (r = .51, p < .01) and inversely correlated with D/D0-glucose (r = -.44, p < .01). They were also significantly positively correlated with matrix metalloproteinase-2 levels in drained dialysate (r = .86, p < .01). Intercellular adhesion molecule-1expression is increased in the peritoneum of a peritoneal injury model in the rat, and soluble intercellular adhesion molecule-1 levels in drained dialysate are associated with peritoneal injury in patients on peritoneal dialysis. These results suggest that soluble intercellular adhesion molecule-1 could be a novel biomarker of peritoneal injury in patients on peritoneal dialysis.

    Peritonitis remains a principal cause of dropout in peritoneal dialysis (PD). The physiological host response to a peritoneal infection involves a rise in numbers of circulating leukocytes to the peritoneal cavity. We evaluated the effects of (1) conventional peritoneal dialysis fluid (PDF), (2) bicarbonate-based PDF, low in glucose degradation products, and (3) non-glucose PDF on peritoneal leukocyte recruitment in response to an inflammatory stimulus using intravital microscopy. The visceral peritoneum was exposed to EBSS, conventional lactate-buffered and bicarbonate/lactate-buffered glucose-based PDF and three lactate-buffered non-glucose PDF-icodextrin, amino acid-based PDF and amino acid/glycerol-based PDF. The number of rolling, adhering and extravasated leukocytes and leukocyte rolling velocity was assessed at different time intervals after stimulation with lipopolysaccharide (LPS). Exposure to LPS dissolved in EBSS dramatically increased the number of rolling, adhering and extravasated leukocytes and decreased leukocyte rolling velocity. Conventional PDF completely abolished LPS-induced leukocyte recruitment. Bicarbonate/lactate-buffered PDF only minimally affected the process of leukocyte recruitment, whereas icodextrin PDF resulted in partial inhibition of the immune response. The amino acid-based and the amino acid/glycerol-based PDF inhibited leukocyte recruitment to a similar extent as conventional PDF. Bicarbonate/lactate-buffered PDF has superior biocompatibility towards peritoneal host defense, in spite of its high glucose concentrations. Lactate-buffered non-glucose containing PDF has substantial inhibitory effects on leukocyte recruitment, indicating that the bioincompatibility of high lactate concentrations and/or low pH may not be underestimated.

    Peritoneal fluid eosinophilia (PFE), which is classically associated with idiopathic eosinophilic peritonitis (EP), has been known as a common event in patients on continuous ambulatory peritoneal dialysis (CAPD). However, our recent retrospective study of CAPD patients following percutaneous catheter placement showed that PFE occurred rarely. The aim of this prospective study was to clarify the incidence and characteristics of idiopathic EP and PFE in patients on CAPD following percutaneous catheter placement. Forty-eight patients on CAPD following percutanous catheter placement were recruited for the present study. Peritoneal dialysis was initiated immediately after catheter insertion without break-in period. A cytological study of dialysate was performed on days 1, 2, 3, 4, 5, 6, 7, 14 and 30 after initiation of CAPD, and then monthly for 6 months. In addition, a cytological study was performed also when a patient revealed abdominal pain or cloudy peritoneal effluent. PFE developed in three (6.3%) patients during the study period. The incidence of idiopathic EP and PFE without any clinical findings suggestive of PD-related peritonitis was 2.1% and 4.2% respectively. All cases of PFE, including idiopathic EP, developed on a mean of 13 day following initiation of CAPD and resolved spontaneously after a mean of 7 days. There was no significant difference in IgE levels or the occurrence of peripheral blood eosinophilia between patients with PFE and those without. Idiopathic EP is infrequent among patients on CAPD following percutaneous catheter placement, but should be differentiated from infectious PD-related peritonitis.

    Icodextrin is a glucose polymer obtained from starch hydrolysis. It is used as an osmotic agent at 7.5% for peritoneal dialysis (PD). Its use in PD has been associated with several side effects separate from the one reported here, the most frequent being sterile peritonitis. Recently, three mechanisms have been proposed to explain the occurrence of sterile peritonitis: allergy to dextrin, production of anti-dextran antibodies, and impurities introduced during manufacture. Here, we report a peritoneal mononucleosis outbreak that is highly suggestive of being a consequence of the last-mentioned mechanism. During the period December 2001 to May 2002, a group of 8 Spanish hospitals whose individual PD programs regularly share information and activity reported 29 cases of sterile peritonitis associated with icodextrin use in continuous ambulatory peritoneal dialysis (CAPD) patients [mean age: 60.7 +/- 14.47 years; 8 women (27.59%), 21 men (72.41%); mean time on PD: 25.21 +/- 35.31 months; mean time on icodextrin: 15.17 +/- 11.03 months]. Of the 29 patients, 51.8% showed no symptoms. The remainder presented with mild abdominal discomfort and anorexia. Only 2 patients showed general malaise, severe nausea, fever, and abdominal pain. The initial white cell count in peritoneal effluent was 512 +/- 386 cells/mL (45.0% +/- 28% neutrophils, 44.92% +/- 32.6% mono-nuclear cells, 7.75% +/- 12% eosinophils). In 5 of the patients, we performed an immunophenotype (CD14) study, demonstrating the monocyte nature of 60%-80% (mean: 70.6%) of the cells. Microbiology cultures were always negative. A rechallenge with the same batches of PD fluid was tried. In 100% of the patients, the clinical and cellular patterns relapsed. No short-term changes in peritoneal function have been observed. The manufacturer informed us that the icodextrin was contaminated with a peptidoglycan. In this sterile peritonitis outbreak with a simultaneous, similar clinical presentation in a group of patients

    ♦ Objective: Management of peritoneal dialysis (PD)-associated peritonitis requires timely intervention by experienced staff, which may not be uniformly available throughout the week. The aim of the present study was to examine the effects of weekend compared with weekday presentation on peritonitis outcomes. ♦ Methods: The study, which used data from the Australia and New Zealand Dialysis and Transplant Registry, included all Australian patients receiving PD between 1 October 2003 and 31 December 2008. The independent predictors of weekend presentation and subsequent peritonitis outcomes were assessed by multivariate logistic regression. ♦ Results: Peritonitis presentation rates were significantly lower on Saturdays [0.46 episodes per year; 95% confidence interval (CI): 0.42 to 0.49 episodes per year] and on Sundays (0.43 episodes per year; 95% CI: 0.40 to 0.47 episodes per year) than all other weekdays; they peaked on Mondays (0.76 episodes per year; 95% CI: 0.72 to 0.81 episodes per year). Weekend presentation with a first episode of peritonitis was independently associated with lower body mass index and residence less than 100 km away from the nearest PD unit. Patients presenting with peritonitis on the weekend were significantly more likely to be hospitalized [adjusted odds ratio (OR): 2.32; 95% CI: 1.85 to 2.90], although microbial profiles and empiric antimicrobial treatments were comparable between the weekend and weekday groups. Antimicrobial cure rates were also comparable (79% vs 79%, p = 0.9), with the exception of cure rates for culture-negative peritonitis, which were lower on the weekend (80% vs 88%, p = 0.047). Antifungal prophylaxis was less likely to be co-prescribed for first peritonitis episodes presenting on weekdays (OR: 0.68; 95% CI: 0.05 to 0.89). ♦ Conclusions: Patients on PD are less likely to present with peritonitis on the weekend. Nevertheless, the microbiology, treatment, and outcomes of weekend and weekday PD peritonitis

    Adherence to a proper diet has a vast impact on the correct course of dialyses, wellbeing, and the results of some laboratory investigations in patients with declining renal failure. The nutritional status of dialysis patients is closely related to food and specific nutrients intake. The aim of study was assessment of dietary habits in dialysis patients. The study included 27 patients peritoneal dialysis (PD) and 92 hemodialysis (HD). In all of dialysis patients the following measurements were taken: body weight and height. The food intake was assessed by 24-hour dietary recall, (according to nutritional components). The portion size was estimated on the "Album of portions of products and dishes". The results were compared with dietary recommendations for dialysis patients and analyzed by computer software Dietetic 2 designed in the Institute of Food and Nutrition in Warsaw but computer program Statistica 7.0 was used for calculations. In all studied dialysis patients an irregular diet were observed. The diet was characterized by a low energetic value and low intake of proteins, carbohydrates, fiber and calcium, as well as by a too high fats. Among women's and man's in both groups were noted underweight: (W in PD patients--7%, M in DO patients--8%, W in HD patients--4%), overweight (W in PD patients--33%, M in DO patients--25%, W in HD patients--38%, M in HD patients--36%) and obesity (W in PD patients--26%, M in DO patients--33%, W in HD patients--22%, M in HD patients--21%). The study revealed that the daily food rations of peritoneal dialysis women were found to have a significantly higher the average intake dietary fiber (18.3 +/- 5.5 g/day) and higher potassium intake (2758.5 +/- 787.5 mg/day) as compared to the average intake dietary fiber (11.7 +/- 5.4 g/ day; p < 0.0001) and potassium intake (1612.9 +/- 822.9 mg/day; p < 0.0001) of hemodialysis women. The regular dietician advice is necessary for monitoring of patients nutrition.

    ♦ Objectives: We explored the relationship between the experience level of nurses and the peritonitis risk in peritoneal dialysis (PD) patients. ♦ Methods: Our observational cohort study followed 305 incident PD patients until a first episode of peritonitis, death, or censoring. Patients were divided into 3 groups according to the work experience in general medicine of their nurses—that is, least experience (<10 years), moderate experience (10 to <15 years), and advanced experience (≥15 years). Demographic characteristics, baseline biochemistry, and residual renal function were also recorded. Multivariate Cox regression was used to analyze the association of risks for all-cause and gram-positive peritonitis with patient training provided by nurses at different experience levels. ♦ Results: Of the 305 patients, 91 were trained at the initiation of PD by nurses with advanced experience, 100 by nurses with moderate experience, and 114 by nurses with the least experience. Demographic and clinical variables did not vary significantly between the groups. During 13 582 patient–months of follow-up, 129 first episodes of peritonitis were observed, with 48 episodes being attributed to gram-positive organisms. Kaplan–Meier analysis showed that training by nurses with advanced experience predicted the longest period free of first-episode gram-positive peritonitis. After adjustment for some recognized confounders, the advanced experience group was still associated with the lowest risk for first-episode gram-positive peritonitis. The level of nursing experience was not significantly correlated with all-cause peritonitis risk. ♦ Conclusions: The experience in general medicine of nurses might help to lower the risk of gram-positive peritonitis among PD patients. These data are the first to indicate that nursing experience in areas other than PD practice can be vital in the training of PD patients. PMID:21719682

    ♦ Background: The aim of the present study was to investigate the relationship between socio-economic status (SES) and peritoneal dialysis (PD)-related peritonitis. ♦ Methods: Associations between area SES and peritonitis risk and outcomes were examined in all non-indigenous patients who received PD in Australia between 1 October 2003 and 31 December 2010 (peritonitis outcomes). SES was assessed by deciles of postcode-based Australian Socio-Economic Indexes for Areas (SEIFA), including Index of Relative Socio-economic Disadvantage (IRSD), Index of Relative Socio-economic Advantage and Disadvantage (IRSAD), Index of Economic Resources (IER) and Index of Education and Occupation (IEO). ♦ Results: 7,417 patients were included in the present study. Mixed-effects Poisson regression demonstrated that incident rate ratios for peritonitis were generally lower in the higher SEIFA-based deciles compared with the reference (decile 1), although the reductions were only statistically significant in some deciles (IRSAD deciles 2 and 4 – 9; IRSD deciles 4 – 6; IER deciles 4 and 6; IEO deciles 3 and 6). Mixed-effects logistic regression showed that lower probabilities of hospitalization were predicted by relatively higher SES, and lower probabilities of peritonitis-associated death were predicted by less SES disadvantage status and greater access to economic resources. No association was observed between SES and the risks of peritonitis cure, catheter removal and permanent hemodialysis (HD) transfer. ♦ Conclusions: In Australia, where there is universal free healthcare, higher SES was associated with lower risks of peritonitis-associated hospitalization and death, and a lower risk of peritonitis in some categories.

    Compliance with the prescribed exchanges in peritoneal dialysis (PD) is important to dialysis success. In the present study, we used measurement of supply inventories to determine compliance by PD patients with the prescribed bag exchanges. We performed home supply inventories by telephone with 30 stable PD patients. Patients who performed at least 90% of prescribed exchanges were considered compliant. Mean age of the patients was 52.8 years. Seven of the patients (23%) had diabetes, and 19 (63%) were women. Peritoneal dialysis was the first choice of renal replacement therapy in 19 patients (63%); the other 11 (37%) had been allocated to PD. Of the 30 patients, 21 (70%) were compliant, and 9 (30%) were not. Among patients choosing PD, 74% were compliant; among those allocated to PD, compliance was found to be 64%. Furthermore, of the compliant patients, 67% had opted for PD and only 33% had been allocated to PD. In the noncompliant group, 56% had opted for and 44% had been allocated to PD. Weekly Kt/V was 1.9 for compliant patients and 1.53 for noncompliant patients. The peritonitis rates in the two groups were similar (0.5 episodes per patient-year for compliant patients and 0.4 episodes per year-patient for noncompliant patients). Participation in the decision-making process improves compliance. Telephone calls about supply inventories is a simple method of monitoring compliance. Developing interventions to enhance compliance in PD patients is a challenge to nurses and to the renal team.

    Catheter-related infections in hemodialysis (HD) and peritoneal dialysis (PD) are one of the most common causes of morbidity and mortality in patients with end-stage renal disease. Staphylococcus aureus in HD patients and S. aureus and Pseudomonas aeruginosa in PD patients are the most common causative organisms isolated. Currently, the diagnostic tests with highest yield in suspected catheter-related infection in HD patients have not been established, and tests used for central venous catheters (CVC) in general are applied. Management of the infected HD catheter and the use of antimicrobial therapy are similar to the measures used for other CVCs, with some specific recommendations. Peritonitis is the most severe complication in PD patients. Improving hygiene conditions in catheter insertion, treatment of S. aureus nasal carriers, regular treatment of the catheter's exit site, and antibiotic lock therapy have been associated with a reduction of infectious episodes in HD and PD patients.

    Patients with end-stage renal disease treated with peritoneal dialysis (PD) are often put on standard one size fits all" regimens, despite having varying degrees of residual renal function (RRF). The present study reports our experience with initiation of PD using 2 icodextrin exchanges daily in patients with RRF corresponding to a weekly Kt/Vurea of at least 1.0. Peritoneal and RRF Kt/Vurea were tracked closely, and total Kt/Vurea was maintained between 1.7 and 2.0. One patient developed a rash and was changed to 3 dextrose exchanges daily. All patients were satisfied with their treatment regimen, and no other adverse events or symptoms were reported.

  12. How to persuade peritoneal dialysis - skeptical hemodialysis fans.

    Already from its early decades, peritoneal dialysis (PD) has proved to be efficient and able to confer similar or better chronic patient survival in comparison with hemodialysis (HD). More recent years allowed many PD therapy advances with further outcomes improvement: mortality, hospitalizations and clinical complications all have been reduced across patient's vintages. Adequacy parameters of PD also compare advantageously with the erroneously named 'high-efficiency' HD which is now facing the limitations of intermittent procedures, frailty of KT/V as measure of adequacy, importance of sustained fluid removal and time of dialysis. Adequacy should also include life satisfaction and PD also compares favorably as a home therapy. The best approach, also the most intelligent and cost-effective, would be not to underestimate a different therapy, but discover how complementary it can be for success of long term patient treatment.

    Valproic acid (VPA) is a commonly used drug for epilepsy, psychiatric disorders and migraine and is frequently used in neurosurgical intensive care units. Though most of its side-effects are mild and transient, certain idiosyncratic side-effects have been attributed to VPA. Valproate induced hyperammonemia (VIH) is one such side-effect. VIH can produce symptoms of encephalopathy known as valproate induced hyperammonemic encephalopathy (VHE). VIH and VHE usually respond to withdrawal of VPA. However, in some cases VHE can be unresponsive to supportive measures and severe enough to be life-threatening. In such cases, dialysis can be used to rapidly reverse hyperammonemia and VHE and can prove to be a lifesaving measure. We report such a case of VIH and life-threatening VHE in a postoperative neurosurgical patient that was managed successfully with peritoneal dialysis.

    Nephropathy may be an independent and contributory risk factor for diabetic macular edema (DME). A 69-year-old man who had previously been treated with panretinal laser photocoagulation for proliferative diabetic retinopathy as well as with steroid and anti-vascular endothelial growth factor injections for DME declined additional treatment for the DME, which was worse in the right eye. The DME was observed without further treatment for the next 36 months. Despite well-controlled blood sugar, blood pressure, and lipid levels, the DME remained unchanged. Peritoneal dialysis was started due to end-stage renal disease. Three months after commencing dialysis, the DME improved significantly. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:834-837.].

    Chronically ill patients often develop uncommon exam findings. A 16-year-old female with end-stage renal disease secondary to immune complex-mediated glomerulonephritis on peritoneal dialysis (PD) developed a pruritic, hyperpigmented reticular rash on her abdomen, sparing the PD catheter insertion site. The rash appeared approximately 6 weeks after initiating PD. She used a heating pad nightly during PD for dialysis drain pain. Testing for systemic and autoimmune disease was negative. She was referred to dermatology, where the diagnosis of erythema ab igne (EAI), a well-described but less well-known hyperpigmented reticular cutaneous eruption caused by chronic exposure to low levels of infrared heat, was confirmed. The eruption is typically painless but is often pruritic. Common sources of heat include fires, stoves, portable heaters, heating pads, and laptop computers. The association between EAI and PD is unknown. Our patient discontinued the heating pad and her rash resolved.

    Residual renal function (RRF) is of paramount importance in patients with end-stage renal disease, with benefits that go beyond contributing to achievement of adequacy targets. Several studies have found that RRF rather than overall adequacy (as estimated from total small solute removal rates) is an essential marker of patient and, to a lesser extent, technique survival during chronic peritoneal dialysis (PD) therapy. In addition, RRF is associated with a reduction in blood pressure and left ventricular hypertrophy, increased sodium removal and improved fluid status, lower serum beta(2)-microglobulin, phosphate and uric acid levels, higher serum hemoglobin and bicarbonate levels, better nutritional status, a more favorable lipid profile, decreased circulating inflammatory markers, and lower risk for peritonitis in PD. As compared with conventional hemodialysis, PD is associated with a slower decrease in RRF. This highlights the usefulness of strategies oriented to preserve both RRF and the long-term viability of the peritoneal membrane. Several factors contributing to the loss of RRF have been identified and should be avoided. Renoprotective drugs and new glucose-sparing, more biocompatible PD regimes may prove useful tools to preserve RRF and peritoneal membrane function in the near future.

    Peritoneal dialysis (PD) is an effective renal replacement strategy for patients suffering from end-stage renal disease. PD offers patient survival comparable to or better than in-center hemodialysis while preserving residual kidney function, empowering patient autonomy, and reducing financial burden to payors. The majority of patients suffering from kidney failure are eligible for PD. In patients with cardiorenal syndrome and uncontrolled fluid status, PD is of particular benefit, decreasing hospitalization rates and duration. This review discusses the benefits of chronic PD, performed by the patient or a caregiver at home. Recognition of the benefits of PD is a cornerstone in stimulating the use of this treatment strategy. PMID:25506238

    While continuous ambulatory peritoneal dialysis (CAPD) offers several advantages over hemodialysis in patients with end-stage renal disease, several complications have been recognized. The intraperitoneal instillation of dialysate increases intra-abdominal pressure and consequently predisposes the patient to leaks and herniations through defects in the abdominal wall. The use of an intraperitoneal radiolabeled colloid has been previously described to image entities such as hernias, patent processus vaginalis, abdominal wall, and diaphragmatic leakage. This study shows a simple, non-invasive method of determining the site of dialysate leak and its importance to assist further patient management. There has been a continuing increase in the number of end stage renal disease patients maintained on chronic peritoneal dialysis (CPD). Many patients choose CPD as their preferred chronic dialysis treatment, though approximately 20% of patients who drop out transfer to hemodialysis annually.[1] Although peritonitis remains the major reason for transfer to hemodialysis, other factors such as exit site infections, catheter-related problems, abdominal wall and inguinal hernias, loss of ultrafiltrations, and poor clearance contribute to CPD technique failure.[2] In order to permit the continuation of long-term therapy with CPD, these complications should be resolved. Routine laboratory evaluation or physical examination can detect some CPD-related problems; however, some patients require more complicated investigations to evaluate their problems properly.

    Introduction Continuous ambulatory peritoneal dialysis (CAPD) peritonitis may develop after endoscopic procedures, and the benefit of prophylactic antibiotics is unclear. In the present study, we investigated whether prophylactic antibiotics reduce the incidence of peritonitis in these patients. Patients and methods We retrospectively reviewed all endoscopic procedures, including esophagogastroduodenoscopy (EGD), colonoscopy, sigmoidoscopy, cystoscopy, hysteroscopy, and hysteroscopy-assisted intrauterine device (IUD) implantation/removal, performed in CAPD patients at Chang Gung Memorial Hospital, Taiwan, between February 2001 and February 2012. Results Four hundred and thirty-three patients were enrolled, and 125 endoscopies were performed in 45 patients. Eight (6.4%) peritonitis episodes developed after the examination. Antibiotics were used in 26 procedures, and none of the patients had peritonitis (0% vs. 8.1% without antibiotic use; p = 0.20). The peritonitis rate was significantly higher in the non-EGD group than in the EGD group (15.9% [7/44] vs. 1.2% [1/81]; p<0.005). Antibiotic use prior to non-EGD examinations significantly reduced the endoscopy-associated peritonitis rate compared to that without antibiotic use (0% [0/16] vs. 25% [7/28]; p<0.05). Peritonitis only occurred if invasive procedures were performed, such as biopsy, polypectomy, or IUD implantation, (noninvasive procedures, 0% [0/20] vs. invasive procedures, 30.4% [7/23]; p<0.05). No peritonitis was noted if antibiotics were used prior to examination with invasive procedures (0% [0/10] vs. 53.8% [7/13] without antibiotic use; p<0.05). Although not statistically significant, antibiotics may play a role in preventing gynecologic procedure-related peritonitis (antibiotics, 0% [0/4] vs. no antibiotics, 55.6% [5/9]; p = 0.10). Conclusion Antibiotic prophylaxis significantly reduced endoscopy-associated PD peritonitis in the non-EGD group. Endoscopically assisted invasive procedures, such as

    Peritonitis is the major complication of peritoneal dialysis (PD). The aim of our present study is to explore the prognostic value of endotoxin level in PD effluent for the prediction of treatment failure in PD-related peritonitis. We studied 325 peritonitis episodes in 223 patients. PD effluent (PDE) was collected every 5 days for endotoxin level and leukocyte count. Patients were followed for relapsing or recurrent peritonitis. We found 20 episodes (6.2%) had primary treatment failure; 41 (12.6%) developed relapsing, 19 (5.8%) had recurrent, and 22 (6.8%) had repeat episodes. Endotoxin was detectable in the PDE of 19 episodes (24.4%) caused by Gram negative organisms, 4 episodes (6.8%) of mixed bacterial growth, and none of the culture negative episodes or those by Gram positive organisms. For episodes caused by Gram negative bacteria, a detectable endotoxin level in PDE on day 5 had a sensitivity and specificity of 66.7% and 83.3%, respectively, for predicting primary treatment failure. In contrast, PDE leukocyte count > 1000 per mm3 on day 5 had a sensitivity and specificity of 88.9% and 89.1%, respectively; the addition of PDE endotoxin assay did not improve the sensitivity or specificity. We conclude that detectable endotoxin in PDE 5 days after antibiotic therapy might predict primary treatment failure in peritonitis episodes caused by Gram negative organisms. However, the sensitivity and specificity of PDE endotoxin assay was inferior to PDE leukocyte count.

    BACKGROUND: Pasteurella species are Gram-negative coccobacilli that are a part of the normal oropharyngeal flora of numerous domestic animals. They have been recognized as a rare but significant cause of peritonitis in patients undergoing peritoneal dialysis (PD). A consensus about management strategies for PD-associated peritonitis caused by Pasteurella species currently does not exist. METHODS: The microbiological database serving the Manitoba Renal Program was searched from 1997 to 2013 for cases of Pasteurella species PD-associated peritonitis, and charts were reviewed. PubMed was searched for case reports and data were abstracted. RESULTS: Seven new local cases and 30 previously reported cases were analyzed. This infection is clinically similar to other forms of PD peritonitis, with household pet exposure appearing to be the strongest risk factor. Cats are the most commonly implicated pet. Direct contact between the pet and the equipment was commonly reported (25 of 37 patients) but was not necessary for infection to develop. The mean duration of treatment was 15 days. Complication rates were low, with only 11% of patients requiring PD catheter removal. There was no mortality reported. CONCLUSION: Pasteurella species are a rare cause of PD-associated peritonitis that can be successfully treated with a two-week course of intraperitoneal antibiotics with a high likelihood of catheter salvage.

    Cell-free DNA (cfDNA) is present in the peritoneal effluent of stable peritoneal dialysis (PD) patients, but there are no data on cfDNA in PD patients with peritonitis. We investigated the variation of peritoneal cfDNA levels subsequent to peritonitis in PD patients. We enrolled 53 PD patients: 30 without any history of systemic inflammation or peritonitis in the last 3 months (group A) and 23 with acute peritonitis (group B). CfDNA was quantified in the peritoneal effluent. Peritoneal samples on days 1, 3, 10, 30 and until day 120 from the start of peritonitis were collected for white blood cells (WBC) count and cfDNA evaluation in group B. Quantitative analysis of cfDNA showed significantly higher levels in group B on day 1, 3, 10 and 30 compared with group A (p < 0.05). A significant positive correlation was observed between cfDNA concentration and WBC on day 1 (rho = 0.89) and day 3 (rho = 0.5) (both, p < 0.05). However, no significant correlation was observed between cfDNA and WBC on days 10 and 30. In group B, peritoneal cfDNA levels tended to progressively decline during follow-up of peritonitis. From this decreasing curve, we estimated that 49 days are necessary to reach the value of 51 genome equivalents (GE)/ml (75th percentile in controls) and 63 days to reach 31 GE/ml (median). Our results demonstrate that cfDNA increases in peritoneal effluent of PD patients with peritonitis and tends to progressively decline in step with peritonitis resolution and membrane repair process. Peritoneal cfDNA quantification could be an innovative method to determine acute damage and an inverse index of the repair process.

    Fungal peritonitis is a relatively uncommon infection in peritoneal dialysis patients. However, it can be associated with significant morbimortality. In recent reports, Candida species and other filamentous fungi have been reported as being aetiological agents. Thermoascus species are ubiquitous, thermophilic fungi, with an anamorph in the Paecilomyces genus. Here we present the first report of fungal peritonitis by Thermoascus crustaceus from Chile. We present the case of an 83-year-old female patient, with a history of cholecystectomy, hernia repair, severe arterial hypertension, hip and knee osteoarthritis and several episodes of peritoneal dialysis with a cloudy exudate. Bacterial cultures were negative. In addition, a history of two months with intermittent fever peaks mainly in the evening was reported. Blood culture bottles inoculated with peritoneal fluid revealed the presence of fungal growth. Morphological and molecular studies allowed us to identify the aetiological agent as Thermoascus crustaceus. An antifungal susceptibility test was performed using the M38-A2 method, developed by the Clinical and Laboratory Standards Institute (CLSI). The MIC values to amphotericin B, itraconazole, voriconazole and echinochandins were 0.5, 0.25, 0.25 and 0.125μg/ml, respectively. Antifungal treatment with amphotericin B was prescribed, with good patient progress. Fungal peritonitis is a very rare entity. Moreover, the spectrum of fungal pathogens continues to expand, a reason for which morphological and molecular studies are necessary for a rapid diagnosis.

    Sleep disorders for patients on dialysis are significant causes of a poorer quality of life and increased morbidity and mortality. No study has evaluated patients undergoing automated peritoneal dialysis (APD) to assess their sleep disorders compared to hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). A total of 166 clinically stable patients who had been on dialysis for at least 3 months were randomly selected for the study and divided into HD, CAPD or APD. Socio-demographic, clinical and laboratory parameters and self-administered questionnaires were collected for the investigation of insomnia, restless legs syndrome (RLS), bruxism, rapid eye movement sleep behavior disorder, excessive daytime sleepiness (EDS), obstructive sleep apnea syndrome (OSAS), sleepwalking, sleep hygiene, depression and anxiety. Insomnia was detected in more than 80 % of patients on the three modalities. OSAS was lower for patients on HD (36 %) than on CAPD (65 %) (p < 0.01) or APD (60 %) (p < 0.04). Patients on APD were more likely to have RLS compared to those on HD or CAPD (p < 0.04) (50 vs. 23 vs. 33 %). No differences among the modalities were found in bruxism, EDS, sleepwalking, sleep hygiene, depression or anxiety. ESRD patients undergoing any one of the three dialysis modalities studied had a high prevalence of sleep disorders. Patients on HD had a lower proportion of OSAS than those on CAPD and APD, which is most likely attributed to their lower body mass indices. The possible causes of higher RLS rates in APD patients have not been established.

    ♦ BACKGROUND: Peritonitis is the most important complication of peritoneal dialysis (PD), and early peritonitis rate is predictive of the subsequent course on PD. Our aim was to calculate the early peritonitis rate and to identify characteristics and predisposing factors in a large nationwide PD provider network in Colombia. ♦ METHODS: This was a historical observational cohort study of all adult patients starting PD between January 1, 2012, and December 31, 2013, in 49 renal facilities in the Renal Therapy Services in Colombia. We studied the peritonitis rate in the first 90 days of treatment, its causative micro-organisms, its predictors and its variation with time on PD and between individual facilities. ♦ RESULTS: A total of 3,525 patients initiated PD, with 176 episodes of peritonitis during 752 patient-years of follow-up for a rate of 0.23 episodes per patient year equivalent to 1 every 52 months. In 41 of 49 units, the rate was better than 1 per 33 months, and in 45, it was better than 1 per 24 months. Peritonitis rates did not differ with age, ethnicity, socioeconomic status, or PD modality. We identified high incidence risk periods at 2 to 5 weeks after initiation of PD and again at 10 to 12 weeks. ♦ CONCLUSION: An excellent peritonitis rate was achieved across a large nationwide network. This occurred in the context of high nationwide PD utilization and despite high rates of socioeconomic deprivation. We propose that a key factor in achieving this was a standardized approach to management of patients.

  11. The impact of relapsing sterile icodextrin-associated peritonitis on peritoneal dialysis outcome.

    The emphasis in peritoneal dialysis (PD) has shifted from a therapy with short-term goals to one of prolonging the life of the peritoneal membrane. Icodextrin (ICO), a starch-derived glucose polymer that is metabolized to maltose, is a valuable osmotic agent in the treatment of PD patients with defective ultrafiltration. However, ICO can cause sterile peritonitis. The manufacturer has recently withdrawn a series of batches of ICO solutions due to evidence of bacterial contamination (a bacterial cell wall breakdown, peptidoglycan). Some cases have been reported of culture-negative ICO-associated peritonitis which relapse on re-challenge. We started to use ICO in chronic uremic PD patients in 1997. Ten patients out of 82 treated in our PD unit were exposed to ICO from 1997-2002. We registered 50 peritonitis episodes in this period: 34 were bacterial and 16 culture-negative. Among the 16 episodes of sterile peritonitis, 6 occurred in patients treated with ICO. Four of the 6 ICO treated patients experienced relapsing culture-negative episodes of peritonitis. We reviewed the records of the four patients. The first episodes of sterile ICO-associated peritonitis occurred between February-May 2002. These were clinically very mild and the only sign was abdominal discomfort and a cloudy dialysate containing a number of WBC/mm(3) ranging from 500-800. Cultures were negative. All the ICO solutions were from the batches withdrawn by the manufacturer. ICO (with new batches of solution) was re-introduced in all patients some weeks later to improve ultrafiltration. A new episode of sterile peritonitis occurred with the same characteristics as described above. Three of the four patients were re-challenged with new batches of ICO solution and again sterile peritonitis occurred. One patient was switched directly to hemodialysis (HD); the others were transferred to a program of automated PD including hypertonic glucose solutions. In 8 months all patients were switched to HD because of

    To discuss findings from an ethnographic study, considering the experiences of patients and families, using peritoneal dialysis at home in the United Kingdom. Peritoneal dialysis is a daily, life-preserving treatment for end-stage renal disease, undertaken in the patient's home. With ever-growing numbers of patients requiring treatment for this condition, the increased use of peritoneal dialysis is being promoted. While it is known that quality of life is reduced when using dialysis, few studies have sought to explore experiences of peritoneal dialysis specifically. No previous studies were identified that adopted an ethnographic approach. A qualitative design was employed, utilising ethnographic methodology. Ethical and governance approvals were gained in November 2010 and data were generated in 2011. Patients (n = 16) and their relatives (n = 9) were interviewed and observed using peritoneal dialysis in their homes. Thematic analysis was undertaken using Wolcott's (1994) three stage process: Description, Analysis and Interpretation. This article describes four themes: initiating peritoneal dialysis; the constraints of peritoneal dialysis due to medicalisation of the home environment and the imposition of rigid timetables; the uncertainty of managing crises and inevitable deterioration; and seeking freedom through creativity and hope of a kidney transplant. This study highlights the culture of patients and their families living with peritoneal dialysis. Despite the challenges posed by the treatment, participants were grateful they were able to self-manage at home. Furthermore, ethnographic methods offer an appropriate and meaningful way of considering how patients live with home technologies.

    In-111-labeled leukocytes were administered to 13 patients on continuous ambulatory peritoneal dialysis in order to locate catheter-associated infections. Using a marker to indicate the catheter exit site, infections of the catheter tunnel were correctly identified prior to surgery in 4 patients with relapsing peritonitis and infections of the exit site were diagnosed in 5 out of 7 patients. The authors conclude that In-111-leukocyte scintigraphy appears to be accurate in diagnosing peritoneal infections of the dialysis catheter tunnel.

    ♦ Background: There is limited available evidence regarding the role of monitoring serum vancomycin concentrations during treatment of peritoneal dialysis (PD)-associated peritonitis. ♦ Methods: A total of 150 PD patients experiencing 256 episodes of either gram-positive or culture-negative peritonitis were included to investigate the relationship between measured serum vancomycin within the first week and clinical outcomes of cure, relapse, repeat or recurrence of peritonitis, catheter removal, temporary or permanent transfer to hemodialysis, hospitalization and death. ♦ Results: Vancomycin was used as an initial empiric antibiotic in 54 gram-positive or culture-negative peritonitis episodes among 34 patients. The median number of serum vancomycin level measurements in the first week was 3 (interquartile range; IQR 1 – 4). The mean day-2 vancomycin level, measured in 34 (63%) episodes, was 17.5 ± 5.2 mg/L. Hospitalized patients were more likely to have serum vancomycin levels measured on day 2 and ≥ 3 measurements in the first week. The peritonitis cure rates were similar between patients with < 3 and ≥ 3 measurements in the first week (77% vs 57%, p = 0.12) and if day-2 vancomycin levels were measured or not (68% vs 65%, p = 0.84). The average day-2 (18.0 ± 5.9 vs 16.6 ± 3.2, p = 0.5), first-week average (18.6 ± 5.1 vs 18.6 ± 4.3, p = 0.9) and nadir (14.5 ± 4.1 vs 13.6 ± 4.2, p = 0.5) vancomycin levels were comparable in patients who did or did not achieve peritonitis cure. Similar results were observed for all other clinical outcomes. ♦ Conclusion: The clinical outcomes of gram-positive and culture-negative peritonitis episodes are not associated with either the frequency or levels of serum vancomycin measurements in the first week of treatment when vancomycin is dosed according to International Society for Peritoneal Dialysis (ISPD) Guidelines.

    We investigated how long continuous ambulatory peritoneal dialysis (CAPD) could be continued in the face of peritoneal sclerosis. 15 CAPD patients with no experience of peritonitis were selected and the time limitation for CAPD was examined retrospectively, based on the dialysate osmolality, serum creatinine concentration, etc.. The values for the dialysate osmolality and serum creatinine concentration increased gradually with the duration of CAPD and were significantly increased from 6 months. 5 patients whose serum creatinine concentration during the first 6 months after initiation of CAPD increased more than 5 mg/dl, could not continue CAPD for more than 24 months because of the appearance of peritoneal membrane failure. When the time limitation for CAPD was assessed in 10 stable patients, close relationships between the mean dialysate osmolality and duration of CAPD (Y = 0.52X + 351.25, r = 0.83, P < 0.01), and between the mean serum creatinine concentration and duration of CAPD (Y = 0.18X + 6.84, r = 0.95, P < 0.001) were recognized. If the practical limitation for CAPD was set at 400 mOsm/l in terms of the dialysate osmolality or 20 mg/dl in terms of serum creatinine concentration, its value became 94.1 months or 73.1 months, respectively. It is concluded that the time limitation for CAPD can be expected to be approximately 6 to 8 years in stable CAPD patients, and we need to resolve CAPD-induced problems involving the peritoneal membrane in order to continue CAPD for more than 10 years.

    Burnout, a syndrome with 3 dimensions of emotional exhaustion, depersonalization, and reduction of personal accomplishment, is very common among hemodialysis nurses, while data are scarce regarding the prevalence of burnout syndrome (BS) among peritoneal dialysis (PD) nurses. This study aimed to assess and compare demographic and professional characteristics and burnout levels in hemodialysis and PD nurses, and to investigate factors that increase the level of burnout in dialysis nurses. A total of 171 nurses from 44 dialysis centers in Turkey were included in a cross-sectional survey study. Data were collected using a questionnaire defining the social and demographic characteristics and working conditions of the nurses as well as the Maslach Burnout Inventory for assessment of burnout level. There was no significant difference in the level of burnout between the hemodialysis and PD nurses groups. Emotional exhaustion and depersonalization scores were higher among the shift workers, nurses who had problems in interactions with the other team members, and those who wanted to leave the unit, as well as the nurses who would not attend training programs. In addition, male sex, younger age, limited working experience, more than 50 hours of working per week, and working in dialysis not by choice were associated with higher depersonalization scores. Personal accomplishment score was lower among the younger nurses who had problems in their interactions with the doctors, who would not regularly attend training programs, and who felt being medically inadequate. Improving working conditions and relations among colleagues, and also providing further dialysis education are necessary for minimizing burnout syndrome. Burnout reduction programs should mainly focus on younger professionals.

    The potential of a starch-derived glucose polymer (molecular weight 16,800) as an osmotic agent for peritoneal dialysis was evaluated. A dialysate isosmotic to uraemic serum (302 [SEM 1.3] mOsm/kg) containing 5% glucose polymer (9.4 mmol/l) was compared with hypertonic (332 [1.0] mOsm/kg) 1.36% glucose (76 mmol/l) solution for ultrafiltration, solute transport, and carbohydrate absorption over 6 h and 12 h peritoneal dialysis exchanges. Glucose polymer solution produced substantially greater net ultrafiltration than glucose, while maintaining stable dialysate osmolality throughout the exchanges. At 6 h and 12 h, 14.4% and 28.1% of glucose polymer had been absorbed, compared with 61.5% and 83.0% of glucose; thus, glucose polymer provided less than 50% of the calorie load of the glucose dialysate per unit volume of ultrafiltrate. There was a 7-9-fold increase in serum maltose with glucose polymer. This high-molecular-weight glucose polymer produced sustained ultrafiltration even when dialysate osmolality remained within the physiological range, by a mechanism resembling "colloid" osmosis. It is a safe and effective osmotic agent but its long-term effects need further study.

    A 55-year-old female haemodialysis patient presented progressive abdominal liquid formation after having been excluded from peritoneal dialysis therapy because of recurrent peritonitis. Ultrasound was suspicious for ascites secondary to sclerosing peritonitis. Computed tomography revealed a thin-walled mesenteric cyst extending from the epigastric to the pelvic region. The cyst was excised incompletely as extensive adhesions were present. Histology was consistent with a mesothelial cyst of inflammatory origin. Three months after surgery, ultrasound detected a local recurrence at the descending colon. This case emphasizes the relation between mesenteric cyst, persistent inflammatory status and preceding peritoneal dialysis complicated by peritonitis.

    The number of patients with end-stage renal disease (ESRD) has rapidly increased, as has the cost of dialysis. Peritoneal dialysis (PD) is an established treatment for ESRD patients worldwide; it has a variety of advantages, including autonomy and flexibility, as well as economic benefits in many countries compared to hemodialysis (HD). However, the long-term survival rate of PD remains poor. Although direct comparison of survival rate between the dialysis modalities by randomized controlled trials is difficult due to the ethical issues, it has always been a crucial point when deciding which dialysis modality should be recommended to patients. Recently, in many countries, including the United States, Brazil, Spain, Australia, and New Zealand, the survival rate in PD patients has significantly improved. PD patient survival in Korea has also improved, but Korean PD patients are known to have higher risk of mortality and major adverse cardiovascular, cerebrovascular events than HD patients. Herein, we further evaluate why Korean PD patients had worse outcomes; we suggest that special attention should be paid to patients with diabetes, coronary artery disease, or congestive heart failure when they choose PD as the first dialysis modality in order to reduce mortality risk.

    Peritoneal dialysis fluids (PDF) differ with respect to osmotic and buffer compound, and pH and glucose degradation products (GDP) content. The impact on peritoneal membrane integrity is still insufficiently described. We assessed global genomic effects of PDF in primary human peritoneal mesothelial cells (PMC) by whole genome analyses, quantitative real-time polymerase chain reaction (RT-PCR) and functional measurements. PMC isolated from omentum of non-uremic patients were incubated with conventional single chamber PDF (CPDF), lactate- (LPDF), bicarbonate- (BPDF) and bicarbonate/lactate-buffered double-chamber PDF (BLPDF), icodextrin (IPDF) and amino acid PDF (APDF), diluted 1:1 with medium. Affymetrix GeneChip U133Plus2.0 (Affymetrix, CA, USA) and quantitative RT-PCR were applied; cell viability was assessed by proliferation assays. The number of differentially expressed genes compared to medium was 464 with APDF, 208 with CPDF, 169 with IPDF, 71 with LPDF, 45 with BPDF and 42 with BLPDF. Out of these genes 74%, 73%, 79%, 72%, 47% and 57% were downregulated. Gene Ontology (GO) term annotations mainly revealed associations with cell cycle (p = 10(-35)), cell division, mitosis, and DNA replication. One hundred and eighteen out of 249 probe sets detecting genes involved in cell cycle/division were suppressed, with APDF-treated PMC being affected the most regarding absolute number and degree, followed by CPDF and IPDF. Bicarbonate-containing PDF and BLPDF-treated PMC were affected the least. Quantitative RT-PCR measurements confirmed microarray findings for key cell cycle genes (CDK1/CCNB1/CCNE2/AURKA/KIF11/KIF14). Suppression was lowest for BPDF and BLPDF, they upregulated CCNE2 and SMC4. All PDF upregulated 3 out of 4 assessed cell cycle repressors (p53/BAX/p21). Cell viability scores confirmed gene expression results, being 79% of medium for LPDF, 101% for BLPDF, 51% for CPDF and 23% for IPDF. Amino acid-containing PDF (84%) incubated cells were as viable as BPDF

    Introduction Hydrothorax is a rare complication of continuous ambulatory peritoneal dialysis (CAPD) which can progress quickly to cause acute respiratory distress. Case presentation We present a 76 year-old female with a past medical history significant for end-stage renal disease (ESRD) on daily home peritoneal dialysis for 2 years presented to the hospital from home with shortness of breath at rest and cough for 2 days prior to admission. She developed severe respiratory distress and had emergent pleurocentesis that released 3.8 L of pleural fluid. The analysis showed significantly high sugar indicative of hydrothorax from CAPD. She underwent thoracotomy with pleurodesis and switched to hemodialysis for 6 weeks before resuming CAPD. Conclusion A high glucose concentration in the pleural fluid is pathognomonic for hydrothorax from dialysis fluid after rule out other possible causes of pleural effusion. Patients who are on CAPD presenting with marked pleural effusion should prompt clinicians to consider the differential diagnosis of pleuroperitoneal communications. PMID:26029545

    Eight adult patients without peritonitis maintained on chronic ambulatory peritoneal dialysis (CAPD) were administered a single oral dose of 320 mg trimethoprim (TMP) and 1600 mg sulfamethoxazole (SMX) to characterize the pharmacokinetics of TMP and SMX. Ten blood samples were drawn following the dose. TMP and SMX-active (SMXA) concentrations were quantified in serum and dialysate. The half-life of TMP and SMXA determined by model independent methods were 33.7 +/- 10.5 h (mean +/- SD) and 13.8 +/- 2.2 h respectively. Total body clearance of TMP was 32.8 +/- 10.1 ml/min and SMXA was 21.9 +/- 6.4 ml/min. CAPD clearance of TMP was 2.27 +/- 0.81 ml/min and SMXA was 1.72 +/- 0.93 ml/min. The average peritoneal dialysate concentrations over the 72-hour collection period of TMP and SMXA were 0.9 +/- 0.1 mg/l and 5.3 +/- 0.8 mg/l respectively. A dose of 320 mg TMP and 1600 mg SMX every 48 hours is recommended for CAPD patients with mild to moderate systemic infections.

    Summary Background and objectives Left ventricular hypertrophy (LVH) is an important end point of dialysis-associated cardiovascular disease. The objective of this study was to evaluate the effect of different pediatric reference systems on the estimated prevalence of LVH in children on chronic peritoneal dialysis (CPD). Design, setting, participants, & measurements Echocardiographic studies in 507 pediatric CPD patients from neonatal age to 19 years were collected in 55 pediatric dialysis units around the globe. We compared the prevalence of LVH on the basis of the traditional cutoff of left ventricular mass (LVM) index (>38.5 g/m2.7) with three novel definitions of LVH that were recently established in healthy pediatric cohorts. Results Application of the new reference systems eliminated the apparently increased prevalence of LVH in young children obtained by the traditional fixed LVM index cutoff currently still recommended by consensus guidelines. However, substantial differences of LVM distribution between the new reference charts resulted in a marked discrepancy in estimated LVH prevalence ranging between 27.4% and 51.7%. Conclusions Although our understanding of the anthropometric determinants of heart size during childhood is improving, more consistent normative echocardiographic data from large populations of healthy children are required for cardiovascular diagnostics and research.

    Peritoneal dialysis (PD) exchange procedure is complex. Patients with cognitive impairment (CI) may require assistance. We studied the prevalence of CI among PD patients, its impact on PD-related peritonitis and the outcome of assisted PD. Cantonese version of Mini-Mental State examination (CMMSE) was performed in 151 patients newly started on PD. Data on patient characteristics including demographics, co-morbidities, blood parameters, medications, and number of PD-related peritonitis in the first 6 months were collected. 151 subjects were recruited. The age of studied patients was 60 ± 15.0 years, and 45% were female. The prevalence of CI was 13.9% using education-adjusted cut-off of CMMSE. Patients older than 65-year-old, female, and lower education level were independent risk factors for CI (OR 9.27 p = 0.001, OR 14.84 p = 0.005, and OR 6.10 p = 0.009, respectively). Age greater than 65-year old is an independent risk factor for PD-related peritonitis but CI was not. Patients requiring assisted PD were of older age (p < 0.001), lower CMMSE (p < 0.001), and scored higher for age-adjusted Charlson Co-morbidity index (p < 0.001). Compared with self-care PD patients, assisted PD patients did not have higher rates exit site infection (p = 0.30) but had a trend of higher PD peritonitis (p = 0.07). CI is common among local PD patients. Overall, CI could not be identified as an independent risk factor for PD peritonitis. There is a higher prevalence of CI among assisted PD patients but helpers may not completely eliminate the risk of PD-related peritonitis.

    Pleural or pericardial effusions secondary to pleuro-peritoneal fistula (PPF) and pericardio-peritoneal fistula (PcPF) are rare but serious complications of peritoneal dialysis (PD). We conducted a 10-year survey across all participating centres in the European Paediatric Dialysis Working Group to review the incidence, diagnostic techniques, therapeutic options and outcome of children on chronic PD with PPF and/or PcPF. Of 1506 children on PD there were ten cases (8 of PPF, 1 each of PcPF and PPF + PcPF), with a prevalence of 0.66%. The median age at presentation was 1.5 [inter-quartile range (IQR) 0.4-2.4] years, and nine children were <3 years. The time on PD before onset of symptoms was 4.3 (IQR 1.3-19.8) months. Eight children had herniae and seven had abdominal surgery in the preceding 4 weeks. Symptoms at presentation were respiratory distress, reduced ultrafiltration and tachycardia. PD was stopped in all children; three were managed conservatively and thoracocentesis was performed in seven (with pleurodesis in 3). PD was restarted in only three children, in two of them with success. In conclusion, PPF and PcPF are rare in children on chronic PD, but are associated with significant morbidity, requiring a change of dialysis modality in all cases. Risk factors for PPF development include age of <3 years, herniae and recent abdominal surgery.

    This study aims to investigate basic clinical features of peritoneal dialysis (PD) patients, their prognostic risk factors, and to establish a prognostic model for predicting their one-year mortality. A national multi-center cohort study was performed. A total of 5,405 new PD cases from China Peritoneal Dialysis Registry in 2012 were enrolled in model group. All these patients had complete baseline data and were followed for one year. Demographic and clinical features of these patients were collected. Cox proportional hazards regression model was used to analyze prognostic risk factors and establish prognostic model. A validation group was established using 1,764 new PD cases between January 1, 2013 and July 1, 2013, and to verify accuracy of prognostic model. Results indicated that model group included 4,453 live PD cases and 371 dead cases. Multivariate survival analysis showed that diabetes mellitus (DM), residual glomerular filtration rate (rGFR), , SBP, Kt/V, high PET type and Alb were independently associated with one-year mortality. Model was statistically significant in both within-group verification and outside-group verification. In conclusion, DM, rGFR, SBP, Kt/V, high PET type and Alb were independent risk factors for short-term mortality in PD patients. Prognostic model established in this study accurately predicted risk of short-term death in PD patients.

    Three children (2 girls and 1 boy) with end-stage renal failure were put in program of continuous ambulatory peritoneal dialysis in the period of 2.5 years (January 1995-September 1997). The age of the children at the treatment onset was 5-12 years. One of three children died due to cardiovascular failure after six-month treatment. Two out of three children had a total of 8 episodes of peritonitis in the period of 37 months during the treatment with peritoneal dialysis. The incidence of peritonitis occurrence in our patients was one episode in 4 patients/months. Most frequent cause for peritonitis occurrence was Staphylococcus aureus in 50% of isolated bacteria. Obtained results in peritoneal equilibration test revealed that the transport and ultrafiltration rate of peritoneal membrane decreased after recurrent peritonitis episodes.

    Summary Background and objectives Left ventricular hypertrophy (LVH) is an independent risk factor and an intermediate end point of dialysis-associated cardiovascular comorbidity. We utilized a global pediatric registry to assess the prevalence, incidence, and predictors of LVH as well as its evolution in the longitudinal follow-up in dialyzed children. Design, setting, participants, & measurements Cross-sectional echocardiographic, clinical, and biochemical data were evaluated in 507 children on peritoneal dialysis (PD), and longitudinal data were evaluated in 128 patients. The 95th percentile of LV mass index relative to height age was used to define LVH. Results The overall LVH prevalence was 48.1%. In the prospective analysis, the incidence of LVH developing de novo in patients with normal baseline LV mass was 29%, and the incidence of regression from LVH to normal LV mass 40% per year on PD. Transformation to and regression from concentric LV geometry occurred in 36% and 28% of the patients, respectively. Hypertension, high body mass index, use of continuous ambulatory peritoneal dialysis, renal disease other than hypo/dysplasia, and hyperparathyroidism were identified as independent predictors of LVH. The use of renin-angiotensin system (RAS) antagonists and high total fluid output (sum of urine and ultrafiltration) were protective from concentric geometry. The risk of LVH at 1 year was increased by higher systolic BP standard deviation score and reduced in children with renal hypo/dysplasia. Conclusions Using height-adjusted left ventricular mass index reference data, LVH is highly prevalent but less common than previously diagnosed in children on PD. Renal hypo/dysplasia is protective from LVH, likely because of lower BP and polyuria. Hypertension, fluid overload, and hyperparathyroidism are modifiable determinants of LVH. PMID:21737855

  12. Membrane transport of several ions during peritoneal dialysis: mathematical modeling.

    PubMed

    2012-09-01

    Peritoneal dialysis utilizes a complex mass exchange device created by natural permselective membranes of the visceral and abdominal muscle tissues. In mathematical modeling of solute transport during peritoneal dialysis, each solute is typically considered as a neutral, independent particle. However, such mathematical models cannot predict transport parameters for small ions. Therefore, the impact of the electrostatic interactions between ions on the estimated transport parameters needs to be investigated. In this study, transport of sodium, chloride, and a third ion through a permselective membrane with characteristics of the peritoneal transport barrier was described using two models: a model with the Nernst-Planck (NP) equations for a set of interacting ions and a model with combined diffusive and convective transport of each ion separately (DC). Transport parameters for the NP model were calculated using the pore theory, while the parameters for the DC model were estimated by fitting the model to the predictions from the NP model. Solute concentration profiles in the membrane obtained by computer simulations based on these two models were similar, whereas the transport parameters (diffusive mass transport parameters and sieving coefficients) were generally different. The presence of the third ion could substantially modify the values of diffusive mass parameter for sodium and chloride ions estimated using the DC model compared with those predicted by NP. The extent of this modification depended on the molecular mass and concentration of the third ion, and the rate of volumetric flow. Closed formulas for the transport parameters of the DC model in terms of the NP model parameters, ion concentration profiles in the membrane, and volumetric flow across the membrane were derived. Their reliable approximations, which include only boundary ion concentrations instead of spatial intramembrane concentration profiles, were formulated. The precision of this approximation

    Peritoneal dialysis confers therapeutic advantages in patients with renal insufficiency and has proven beneficial in other indications, such as removal of excess metabolites or overdosed drugs. However, it is used in only about 10% of the dialyzed population worldwide, partly owing to the lower clearance rate compared with hemodialysis. We have developed a dialysis medium based on liposomes with a transmembrane pH gradient (basic or acidic aqueous core) that could improve the efficacy of peritoneal dialysis, specifically for the removal of excess metabolites or overdosed drugs. These scavenging vesicles are able to extract ionizable drugs and toxic metabolites into the peritoneal space and can be easily withdrawn from the body at the end of dialysis. This approach was used to successfully remove ammonia from rats with a greater extraction efficiency than traditional peritoneal dialysis, and may therefore prove useful in the treatment of severe hyperammonemia. Liposomal dialysis was also used to concentrate exogenous compounds in the rat peritoneal cavity, allowing for sequestration of several drugs that are frequently involved in overdose in people. In particular, liposomal dialysis counteracted the hypotensive action of the cardiovascular drug verapamil more efficiently than did control dialysis in a rat model of drug overdose. These findings highlight the versatility and advantage of this liposome-based approach for emergency dialysis. Copyright © 2014, American Association for the Advancement of Science.

    Insulin resistance has been associated with cardiovascular disease in peritoneal dialysis patients. Few studies have addressed the impact of fast transport status or dialysis prescription on insulin resistance. The aim of this study was to test whether insulin resistance is associated with obesity parameters, peritoneal transport rate, and glucose absorption. Insulin resistance was evaluated with homeostasis model assessment method (HOMA-IR), additionally corrected by adiponectin (HOMA-AD). Enrolled patients were prevalent nondiabetics attending at Santo António Hospital Peritoneal Dialysis Unit, who were free of hospitalization or infectious events in the previous 3 months (51 patients aged 50.4 ± 15.9 years, 59% women). Leptin, adiponectin, insulin-like growth factor-binding protein 1 (IGFBP-1), and daily glucose absorption were also measured. Lean tissue index, fat tissue index (FTI), and relative fat mass (rel.FM) were assessed using multifrequency bioimpedance. Patients were categorized according to dialysate to plasma creatinine ratio at 4 hours, 3.86% peritoneal equilibration test, and obesity parameters. Obesity was present in 49% of patients according to rel.FM. HOMA-IR correlated better with FTI than with body mass index. Significant correlations were found in obese, but not in nonobese patients, between HOMA-IR and leptin, leptin/adiponectin ratio (LAR), and IGFBP-1. HOMA-IR correlated with HOMA-AD, but did not correlate with glucose absorption or transport rate. There were no significant differences in insulin resistance indices, glucose absorption, and body composition parameters between fast and nonfast transporters. A total of 18 patients (35.3%) who had insulin resistance presented with higher LAR and rel.FM (7.3 [12.3, interquartile range] versus 0.7 [1.4, interquartile range], P<0.001, and 39.4 ± 10.1% versus 27.2 ± 11.5%, P=0.002, respectively), lower IGFBP-1 (8.2 ± 7.2 versus 21.0 ± 16.3 ng/ml, P=0.002), but similar glucose absorption and

    A known complication of peritoneal dialysis is the movement of dialysate into the pleural space, termed hydrothorax. Peritoneal dialysis-related hydrothorax is almost uniformly right-sided and represents one of many presentations of the porous diaphragm syndrome. In addition to diaphragm porosity, the inherent intestinal circulation, lower hydrostatic pressure in the right upper quadrant and liver capsule may contribute to this right-sided predominance. Similar right-sided presentations have been described in Meigs syndrome, bilious effusions with gastric or duodenal perforations, hepatic hydrothorax and nephrotic syndrome-related chylothorax. PD-related hydrothorax can be repaired by pleurodesis or video-assisted thoracoscopy followed by resumption of peritoneal dialysis.

    Eosinophilic peritonitis is a well-described complication of peritoneal dialysis and is often associated with either a reaction to the dialysis system constituent (tubing, sterilant or solution) or an underlying bacterial or fungal reaction. We report a case of eosinophilic peritonitis, which is treated by oral prednisone acetate therapy. A 43-year-old female patient developed end-stage renal disease and underwent continuous ambulatory peritoneal dialysis for 2.5 years. The patient received 2,000 ml of 1.5% dialysis solution (PD2) with three exchanges daily and 2,000 ml of 2.5% PDF overnight (PD2). She went to the consultation because of a constant turbid peritoneal dialysis effluent for 3 months without abdominal pain. Repeated peritoneal effluent samples showed an elevated white blood cell count of 500 cells/mm3, with 87% eosinophils. The peripheral blood test revealed a white blood cell count of 3.8 × 109/l, with 32.2% eosinophils. Etiology like bacterial and fungal infection was excluded by peritoneal fluid culture. Turbidness persisted in spite of diagnostic antibiotic treatment. Given the fact that we found a significant elevation of eosinophils in the peripheral blood and an absolute increase in the eosinophil count of >30/mm3 in dialysis fluid (up to 400/mm3 in our patient), obvious dialysate effluent turbidness, negative results of repeated peritoneal fluid cultures, inefficacy of antibiotic therapy, and negativity of serum tumor and immunological markers, we drew the conclusion that the patient had idiopathic eosinophilic peritonitis. Oral corticosteroid was administered at once (20 mg prednisone acetate daily), which was gradually weaned off and stopped over an 8-week period. Afterwards, the dialysis effluent became clear, and the cytological analysis showed that the white blood cell count decreased to 1 × 106/l, with no eosinophils. This case reminds us that the diagnosis of eosinophilic peritonitis should be considered when repeated cultures are

    Peritoneal dialysis (PD)-related peritonitis is a common and morbid complication of PD. Bacteria are able to create a biofilm on the PD catheter, which can be a source of recurrent infection. Biofilms undergo a phenotypic change resulting in increased antibiotic resistance. ♢ 21 clinical isolates of different patients with PD peritonitis secondary to Staphylococcus aureus were collected. They were analyzed for their antibiotic susceptibility in the planktonic form using the standard minimum inhibitory concentration (MIC) and in a biofilm using minimum biofilm eradication concentration (MBEC). Chi-square was used to compare the sensitivity results. ♢ The isolates were susceptible to all the antibiotics tested using MIC. Every antibiotic except gentamicin lost its efficacy when the bacteria were grown in a biofilm (p > 0.05). The change in susceptibility was statistically significant to a level of p < 0.001 for all antibiotics tested. ♢ In PD peritonitis that is long standing, recurrent, or not responsive to therapy, MBEC testing should be considered as a biofilm may be present. Gentamicin should be strongly considered over other agents for empiric gram-negative coverage as it may be providing synergy in the setting of Staphylococcus aureus. Also, the newer anti-staphylococcal drugs should be tested for their performance in a biofilm using the MBEC method.

    Systemic inflammation, as evidenced by elevated inflammatory cytokines, is a feature of advanced renal failure and predicts worse survival. Dialysate IL-6 concentrations associate with variability in peritoneal small solute transport rate (PSTR), which has also been linked to patient survival. Here, we determined the link between systemic and intraperitoneal inflammation with regards to peritoneal membrane function and patient survival as part of the Global Fluid Study, a multinational, multicenter, prospective, combined incident and prevalent cohort study (n=959 patients) with up to 8 years of follow-up. Data collected included patient demographic characteristics, comorbidity, modality, dialysis prescription, and peritoneal membrane function. Dialysate and plasma cytokines were measured by electrochemiluminescence. A total of 426 survival endpoints occurred in 559 incident and 358 prevalent patients from 10 centers in Korea, Canada, and the United Kingdom. On patient entry to the study, systemic and intraperitoneal cytokine networks were dissociated, with evidence of local cytokine production within the peritoneum. After adjustment for multiple covariates, systemic inflammation was associated with age and comorbidity and independently predicted patient survival in both incident and prevalent cohorts. In contrast, intraperitoneal inflammation was the most important determinant of PSTR but did not affect survival. In prevalent patients, the relationship between local inflammation and membrane function persisted but did not account for an increased mortality associated with faster PSTR. These data suggest that systemic and local intraperitoneal inflammation reflect distinct processes and consequences in patients treated with peritoneal dialysis, so their prevention may require different therapeutic approaches; the significance of intraperitoneal inflammation requires further elucidation.

    To analyze data on 503 chronic peritoneal dialysis (CPD) catheters implanted between 1986 and 2000 in pediatric patients enrolled in the Italian Registry of Pediatric Chronic Peritoneal Dialysis (the Registry), comparing three different time periods: 1986-1990, 1991-1995, and 1996-2000. Retrospective study. 23 dialysis centers participating in the Registry. Data were collected from questionnaires filled in every year. The information for each peritoneal catheter included type, site and technique of insertion, exit-site orientation, exit-site care, complications, survival, and reason for removal. 503 catheters were implanted in 363 pediatric patients aged younger than 15 years at the start of CPD: 97 catheters in patients under 2 years of age, 67 in patients aged 2-5 years, and 339 in patients over 5 years of age. Mean patient age at onset of CPD was 8.0 +/- 5.1 years. All catheters were surgically implanted and omentectomy was performed in 82.4% of cases. The catheters used were Tenckhoff [468 (93.0%): 443 double cuff, 25 single cuff] and double-cuffed Valli [35 (7.0%)]. The entry site was in the midline in 153 cases (30.4%) and paramedian in 350 (69.6%). During 9048 dialysis-months we observed 451 catheter-related complications, yielding an incidence of 1 episode/20.1 CPD-months: 330 catheter infections (exit-site and/or tunnel infections), 26 leakages, 26 dislocations, 24 obstructions, 22 cuff extrusions, 6 hemoperitoneums, 17 others. 171 catheters were removed due to catheter-related causes; exit-site and/or tunnel infections were the main cause for removal (75.4%), followed by obstruction, dislocation, outer-cuff extrusion, and leakage. Younger children (< 2 years) had a higher risk of infectious causes of catheter removal compared to children aged 2-5 years (p = 0.004) and over 5 years of age (p = 0.002). During the 15-year observation period, a significant reduction in the incidence of leakage was observed and risk of leakage was lower in catheters with

    The impact of icodextrin (ico) on peritoneal dialysis (PD) extension and patient survival is well established. Predominantly, ico-based solutions were prescribed in high-transporter PD patients. Advantages of the ico-based solutions include increased biocompatibility, avoidance of glucotoxicity, enhanced ultrafiltration failure (UF), sodium removal rates, better metabolic and blood pressure control. Bimodal solutions and twice daily exchanges of ico-based solutions are two newly introduced strategies to avoid glucose exposure and/or enhance UF in PD patients with UF failure. In addition, a simplified schedule of PD using a single nocturnal exchange of ico in patients with refractory congestive heart failure may represent an alternative option to manage fluid removal and azotaemia. The use of a simplified schedule of PD with only two ico exchanges or a single ico exchange is a challenging approach for end-stage renal disease patients with preserved residual function who desire to initiate PD.

    Peritoneal dialysis (PD) center is not possible to operate if there is no availability of dedicated PD nurse. Generally, the nurse has to play many roles, including educator coordinator, and sometimes leader. As professionalism, the PD nurses need to have both theoretical and practical skills. With the tremendous leap of PD population after the launch of "PD First" policy in Thailand, the shortage of skillful PD nurse is concerned. Hence, the nationwide PD nurse training course was established with the collaborations of many organizations and institutes. Until now, 3 generations of 225 PD nurses are the productions of the course. This number represents 80 percent of PD nurses distributed throughout the whole nation. The survey operated in the year 2010 demonstrated that the output of the course was acceptable in terms of quality since most of the trained PD nurses had a confidence in taking care of PD patients. The quality of patient care is good as indicated by KPIs.

    Peritoneal dialysis (PD) patients are commonly required to transfer to hemodialysis (HD), however the literature describing the outcomes of such transfers is limited. The aim of our study was to describe the predictors of these transfers and their outcomes according to vascular access at the time of transfer. A retrospective cohort study using registry data of all adult patients commencing PD as their initial renal replacement therapy in Australia or New Zealand between 2004 - 2010 was performed. Follow-up was until 31 December 2010. Logistic regression models were constructed to determine possible predictors of transfer within both 6 and 12 months of PD commencement. Cox analysis and competing risks regression were used to determine the predictors of survival and transplantation post-transfer. The analysis included 4,781 incident PD patients, of whom 1,699 transferred to HD during the study period. Logistic models did not identify any clinically useful predictors of transfer within 6 or 12 months (c-statistics 0.54 and 0.55 respectively). 67% of patients commenced HD with a central venous catheter (CVC). CVC use at transfer was associated with increased mortality (hazard ratio 1.37, 95% confidence interval (CI) 1.11 - 1.68, p = 0.003) and a borderline significant reduction in the incidence of transplantation (subhazard ratio 0.76, 95% CI 0.58 - 1.00, p = 0.05). It is difficult to predict the transfer to HD for incident PD patients. PD patients who commence HD with a CVC have a higher risk of mortality and a lower likelihood of undergoing renal transplantation. Copyright © 2015 International Society for Peritoneal Dialysis.

    ♦ Vascular calcification is strongly associated with cardiovascular disease and mortality. However, some factors related to vascular calcification in patients with end-stage renal disease receiving peritoneal dialysis (PD) remain unknown. This study aimed to evaluate the associations of osteoprotegerin (OPG), osteopontin (OPN), osteocalcin (OCN), fibroblast growth factor 23 (FGF-23), magnesium, and phosphate clearance with vascular calcification in PD subjects, assessed by plain radiographs. ♦ Simple vascular calcification scores (SVCS) obtained from plain X-rays of the pelvis and hands, and the Kauppila Index (KI) from lateral lumbar X-rays were assessed in 76 adults receiving PD for ≥ 6 months (43 women, median age 39 years, median time on PD 1.4 years). Levels of OPG, OPN, OCN, and FGF-23 were determined by luminometry. ♦ Serum OPG levels were higher in subjects with vascular calcification (n = 22 with SVCS > 3; n = 19 with KI > 7) compared with those with less calcification (p < 0.001). Spearman's correlation coefficients between OPG and SVCS and KI were r = 0.49 and r = 0.51, respectively (both p < 0.001). Subjects with vascular calcification had significantly lower renal phosphate clearance. Multiple regression analysis showed that vascular calcification assessed by SVCS was associated with age (r = 0.2, p = 0.042), diabetes mellitus (r = 2.4, p < 0.001), body mass index (BMI) (r = 0.09, p = 0.037), and OPG (r = 0.22, p = 0.001). Vascular calcification assessed by KI was associated with age (r = 0.16, p < 0.001), time on PD (r = 0.54, p = 0.001) and OPG (r = 0.08, p = 0.04). Osteocalcin, OPN, FGF-23, and magnesium were not associated with vascular calcification. ♦ Higher levels of OPG were consistently associated with vascular calcification in subjects on PD.

    Over recent decades, rapid progress in information and telecommunications technology has led to the application of these technologies in the medical field. In 1999, we reported on a telemedicine system (version 1.0) that used an automated peritoneal dialysis machine to collect data on patients with end-stage renal disease. After 2002, we focused on using cellular telephones in a new telemedicine system (version 2.0) to monitor patient data at home, including blood pressure (BP), heart rate, body weight, urine volume, and blood glucose. By 2003, we had developed a fully automatic system called I-converter (version 3.0) to collect data from a fully automatic device and send it via cellular telephone. After the fully automatic device measures a patient's BP, I-converter sends the data directly to the main server in our central data center. That server is directly connected to Web site by application service provider (ASP) technology. Recently, to make the system simpler, we developed a new version called D-converter (version 4.0). The telephone used in this new system is a Personal Handy-phone System (PHS). The PHS has several advantages: high-speed data transmission, low power output, little electromagnetic interference with medical devices, and easy locating of patients. The D-converter system uses a small computer and a PHS card called a Dopa card. Our telemedicine systems monitor continuous ambulatory peritoneal dialysis (CAPD) patients at home. For elderly and handicapped patients, these systems are very advantageous because they reduce visits to the outpatient clinic. In addition, data can be monitored at the patient's home in real time. The present paper reports our recent advances in telemedicine systems for CAPD patients.

    Peritoneal dialysis (PD) is used as an alternative to hemodialysis in end-stage renal disease (ESRD). Icodextrin has been used as a hyperosmotic agent in PD. The aim of the study was to assess two different point-of-care testing (POCT) glucose strips, affected and not affected by icodextrin, with serum glucose concentrations of the patients using and not using icodextrin. Fifty-two chronic ambulatory peritoneal dialysis (CAPD) patients using icodextrin (Extraneal®) and 20 CAPD patients using another hyperosmotic fluid (Dianeal®) were included in the study. Duplicate capillary and serum glucose concentrations were measured with two different POCT glucose strips and central laboratory hexokinase method. Assay principles of glucose strips were based on glucose dehydrogenase-pyrroloquinoline quinone (GDH-PQQ) and a mutant variant of GDH (Mut Q-GDH). The results of both strips were compared with those of hexokinase method. Regression equations between POCT and hexokinase methods in icodextrin group were y = 2.55x + 1.12 mmol/l and y = 1.057x + 0.16 mmol/l for the GDH-PQQ and Mut Q-GDH methods, respectively. The mean difference between the results of hexokinase and those of GDH-PQQ and Mut Q-GDH in icodextrin group was 3.41 ± 1.56 and 0.72 ± 0.64 mmol/l, respectively. However, the mean differences were found much lower in the control group; 0.64 mmol/l for GDH-PQQ and 0.52 mmol/l for Mut Q-GDH. Compared to GDH-PQQ, glucose strips of Mut Q-GDH correlated better with hexokinase method in PD patients using icodextrin. © 2015 Wiley Periodicals, Inc.

    ♦ The standard treatment of peritoneal dialysis (PD)-associated peritonitis (PD-peritonitis) is intraperitoneal (IP) administration of antibiotics. Only limited data on the pharmacokinetics and appropriateness of contemporary dose recommendations of IP cefalothin and cefazolin exist. The aim of this study was to describe the pharmacokinetics of IP cefalothin and cefazolin in patients treated for PD-peritonitis. ♦ As per international guidelines, IP cefalothin or cefazolin 15 mg/kg once daily was dosed with gentamicin in a 6-hour dwell to patients with PD-peritonitis during routine care. Serial plasma and PD effluent samples were collected over the first 24 hours of therapy. Antibiotic concentrations were quantified using a validated chromatographic method with pharmacokinetic analysis performed using a non-compartmental approach. ♦ Nineteen patients were included (cefalothin n = 8, cefazolin n = 11). The median bioavailability for both antibiotics exceeded 92%, but other pharmacokinetic parameters varied markedly between antibiotics. Both antibiotics achieved high PD effluent concentrations throughout the antibiotic dwell. Cefazolin had a smaller volume of distribution compared with cefalothin (14 vs 40 L, p = 0.003). The median trough total plasma antibiotic concentration for cefazolin and cefalothin during the dwell differed (plasma 56 vs 13 mg/L, p < 0.0001) despite a similar concentration in PD effluent (37 vs 38 mg/L, p = 0.58). Lower antibiotic concentrations were noted during PD dwells not containing antibiotic, particularly cefalothin, which was frequently undetectable in plasma and PD effluent. The median duration that the unbound antibiotic concentration was above the minimum inhibitory concentration (MIC) was approximately 13% (plasma) and 25% (IP) for cefalothin, and 100% (plasma and IP) for cefazolin, of the dosing interval. ♦ When IP cefalothin or cefazolin is allowed to dwell for 6 hours, sufficient PD effluent concentrations are present for

    Churchill, D N

    1998-12-01

    For patients with end-stage renal disease treated with peritoneal dialysis, prospective cohort studies using multivariate statistical analysis have shown an association between greater urea clearance and a decreased relative risk for death. The recommended weekly Kt/V for urea is 2.0, with the corresponding creatinine clearance (CrCl) of 60 L/1.73 m2. This is considered adequate dialysis but fails to define optimum urea and CrCl targets. The assumption that renal and peritoneal clearances are equivalent has been challenged by circumstantial data and is probably untenable. The relative importance of these clearances requires definition. The suggestion that CrCl is a more important indicator of adequacy of dialysis is confounded by association with renal, rather than peritoneal, clearance and perhaps by the early referral and initiation of dialysis. Recent reports have shown an association between increased peritoneal membrane transport and an increased relative risk for technique failure and/or death. Patients with higher peritoneal transport should have greater clearance of urea and creatinine and better clinical outcomes. Possible explanations for this apparent contradiction include the adverse effects of increased glucose absorption, malnutrition, and fluid overload, the latter caused by decreased ultrafiltration. Available data suggest an important role for the failure of ultrafiltration among patients treated with continuous ambulatory peritoneal dialysis (CAPD). Strategies to improve the clearance of urea and creatinine include the preservation of residual renal function and increased peritoneal clearance. Loss of residual renal function may be delayed by the avoidance of nephrotoxic drugs and angiographic dye. Peritoneal clearance can be enhanced by a combination of increased volume and frequency of peritoneal dialysis cycles. Ultrafiltration failure, but not protein loss, can be addressed with shorter cycles with nocturnal peritoneal dialysis. Development of

    Peritoneal dialysis (PD) as a therapy with all its advantages has not grown as would have been expected except in certain pockets, notably in Asia. In our opinion, from patient and their family interviews, a perception among prospective PD patients of inaccessibility to the referral PD Unit (RPU), usually for patients from rural areas in far flung places, inaccessible due to difficult terrain or long distances, play a strong role against the choice of PD as their modality choice for end-stage renal disease. We decided to address this issue by adopting novel initiatives such as easy access to the RPU through usage of internet and mobile phones from the patient homes especially in addressing the more clinically relevant infectious complications such as peritonitis and exit site infections with immediate treatment management responses from the RPU. In addition, we found that inherently the rural PD patients had several advantages over their urban counterparts and also over their hemodialysis (HD) counterparts in many socioeconomic, emotional support and nutritional parameters. We enhanced these advantages with an intensive home visit program. This two pronged approach has paid dividends in that our rural PD patients do as well, if not better than the urban PD and the HD patients, contrary to prevailing international experience.

    Mexico is struggling to gain a place among developed countries; however, there are many socioeconomic and health problems still waiting for resolution. While Mexico has the twelfth largest economy in the world, a large portion of its population is impoverished. Treatment for end-stage renal disease (377 patients per million population) is determined by the individual's access to resources such as private medical care (approximately 3%) and public sources (Social Security System: approximately 40%; Health Secretariat: approximately 57%). With only 6% of the gross national product spent on healthcare and most treatment providers being public health institutions that are often under economic restrictions, it is not surprising that many Mexican patients do not receive renal replacement therapy. Mexico is still the country with the largest utilization of peritoneal dialysis (PD) in the world, with 18% on automated PD, 56% on continuous ambulatory PD (CAPD), and 26% on hemodialysis. Results of PD (patient morbi-mortality, peritonitis rate, and technique survival) in Mexico are comparable to other countries. However, malnutrition and diabetes mellitus are highly prevalent in Mexican patients on CAPD programs, and these conditions are among the most important risk factors for a poor outcome in our setting.

    The kidney is a complex and vital organ, regulating the electrolyte and fluid status of the human body. As hemodialysis (HD) and peritoneal dialysis (PD) are forms of renal replacement therapy and not an actual kidney, they do not possess the same physiologic regulation of both fluid and electrolytes. Precise regulation of fluid and electrolytes in the HD and PD population remains a constant challenge. In this review, fluid status of both HD and PD will be examined, as well as sodium, potassium, phosphorous, and calcium. Each electrolyte will be analyzed by its physiological significance, the complications that arise when a proper balance cannot be maintained, and methods to correct these imbalances. An overview of the fluid compartments and volume of distribution within the body will be discussed. Ultrafiltration, a modality used in both forms of renal replacement therapy, will be defined, along with its impact on fluid status. Fluid assessment will be addressed, along with proper maintenance of fluid homeostasis. By having an understanding of the pathophysiology behind the fluid and electrolyte abnormalities that occur in end-stage renal disease, one can direct proper management with medications, diet, and alterations in dialysis to provide patients with the most optimal form of renal replacement therapy available.

    Mesenchymal stroma cells (MSCs) have potential as an emerging cell therapy for treating many different diseases, but discovery of the practical sources of MSCs is needed for the large-scale clinical application of this therapy. This study was to identify MSCs in peritoneal dialysis (PD) effluents that were discarded after PD. The effluents were collected from patients who were on the dialysis for less than 1 month. Adherent cells from the effluents were isolated by incubation in serum-containing medium in plastic culture dishes. Cell surface markers were determined by a flow cytometric analysis, and the in vitro differentiation to chondrocytes, osteocytes or adipocytes was confirmed by staining with a specific dye. After four passages, these isolated cells displayed the typical morphology of mesenchymal cells in traditional 2-D cultures, and were grown to form spherical colonies in 3-D collagen cultures. Flow cytometric analysis revealed that the unsorted cells from all of seven patient samples showed robust expression of typical mesenchymal marker CD29, CD44, CD73, CD90 and CD166, and the absence of CD34, CD79a, CD105, CD271, SSEA-4, Stro-1 and HLA-DR. In differentiation assays, these cells were induced in vitro to chondrocytes, osteocytes or adipocytes. In conclusion, this preliminary study suggests the presence of MSCs in the "discarded" PD effluents. Further characterization of the phenotypes of these MSCs and evaluation of their therapeutic potential, particularly for the prevention of PD failure, are needed.

    Since it was introduced in 1976, continuous ambulatory peritoneal dialysis (CAPD) has won acceptance in many centres and it is now regarded as an important alternative to haemodialysis. CAPD patients have comparable and, in some circumstances, better survival than those on chronic haemodialysis. It is indicated particularly in patients with diabetes mellitus, cardiovascular instability and at the extremes of life. The success of kidney transplantation is similar in those maintained on CAPD and on haemodialysis. CAPD also achieves satisfactory physical and psychological rehabilitation, and the quality of life, including the level of sexual function, is similar during CAPD and haemodialysis. Women on CAPD menstruate more often than those on haemodialysis. CAPD provides adequate clearance of metabolic wastes, maintains fluid balance and ameliorates neurotoxic cognitive dysfunction. CAPD gives control of hypertension and anaemia which is superior to that on haemodialysis. Neuropathy remains stable but osteitis fibrosa seems to progress. CAPD is the most economical of the various forms of dialysis. We conclude that CAPD is an adequate form of replacement and should be made available in every nephrology centre providing treatment for patients with end-stage renal disease. PMID:3909582

  13. Present status and future of peritoneal dialysis in Japan.

    The results of a nationwide statistical survey of peritoneal dialysis (PD) in Japan (PD registry) were reported at the end of 2012. There were 9,514 PD patients at the end of 2012 (3.1%), indicating 128 fewer than in the 2011 survey (9,642 patients). There were 347 non-PD+catheter patients, and 175 patients were started on PD in 2012 but were switched to another therapy in the same year. The sum of these 522 patients and the total number of PD patients (i.e. the total number of PD-therapy-related patients) was 10,036 (522 + 9,514). The PD-only patients numbered 7,323 (80.4%), and the PD+hemodialysis (HD) patients numbered 1,788 (19.6%). Of these 9,111 PD patients, 1,428 patients (15.7%) underwent HD once per week; 219 patients (2.4%), twice per week; and 55 patients (0.6%), three times per week. The PD+HD patients (1,788) accounted for 19.6% of all PD patients. In addition, 39.8% of PD patients were using the poly-glucose dialysis solution icodextrin (Extraneal). Around 40% of PD patients were using icodextrin, a much higher percentage than in other countries. What is the likelihood that the number of PD patients in Japan will gradually decrease (or increase) in the future? Regarding the dialysis trend in Japan, it is unlikely that the number of PD patients will increase. I think that if the government greatly increases the medical insurance coverage of PD treatment, the number of PD patients in Japan will increase as much as it recently has in the United States. If not, it is extremely unlikely that there will be a large increase in the number of PD patients in Japan.

    Previous studies showed that frailty is prevalent in both pre-dialysis and dialysis patients. However, the prevalence and prognostic implication of frailty in Chinese peritoneal dialysis (PD) patients remain unknown. We used a validated questionnaire to determine the Frailty Score of 193 unselected prevalent PD patients. All patients were then followed for 2 years for their need of hospitalization and mortality. Amongst the 193 patients, 134 (69.4%) met the criteria of being frail. Frailty Score significantly correlated with Charlson's comorbidity score (r = 0.40, p < 0.0001), Malnutrition Inflammation Score (r = 0.59, p < 0.0001), and inversely with Subjective Global Assessment score (r = -0.44, p < 0.0001). Frailty was closely associated with the need of hospitalization. Patients with nil, mild, moderate, and severe frailty required 2.4 ± 6.0, 1.6 ± 1.6, 2.7 ± 2.5, 5.2 ± 4.8 hospital admissions per year, respectively (p < 0.0001), and they stayed in hospital for 6.4 ± 9.2, 5.3 ± 6.2, 10.0 ± 10.4, 12.9 ± 20.1 days per hospital admission, respectively (p < 0.0001). However, Frailty Score was not an independent predictor of patient or technique survival. Frailty is prevalent among Chinese PD patients. Frail PD patients have a high risk of requiring hospitalization and their hospital stay tends to be prolonged. Early identification may allow timely intervention to prevent adverse health outcomes in this group of patients. © 2016 The Author(s) Published by S. Karger AG, Basel.

    Human herpesvirus 6 (HHV-6) infection occurs worldwide and can be reactivated from latency during periods of immunosuppression, especially after organ transplantation. No previous study has evaluated the influence of dialysis type on HHV-6 infection. The aim of the present study was to determine the prevalence of HHV-6 antibodies in hemodialysis (HD) and peritoneal dialysis (PD) patients. We studied 36 PD patients, 35 HD patients, and 20 healthy subjects, all with no history of organ transplantation. After systematic inquiries and a physical examination, blood was drawn for determination of biochemical parameters, cytomegalovirus immunoglobulin M (IgM) and immunoglobulin G (IgG), hepatitis B surface antigen, and the hepatitis C and human immunodeficiency virus antibodies. Titers of HHV-6 IgM and IgG antibodies were determined by ELISA. Titers for HHV-6 IgM antibody were positive in 9 HD patients (25.7%), 8 PD patients (22.2%), and 2 control subjects (10.0%, p > 0.05). More HD patients (20.0%) than PD patients (5.6%, p = 0.07) or control subjects (0.0%, p = 0.03) were positive for HHV-6 IgG antibody. In HD patients, HHV-6 IgG seropositivity and duration of dialysis were positively correlated (R = 0.33, p = 0.05). Infection with HHV-6 is not rare in PD and HD patients. In addition, HHV-6 IgG seropositivity was significantly higher in HD patients than in control subjects and approached significance when compared with seropositivity in PD patients. Moreover, in HD patients, HHV-6 IgG seropositivity correlated with duration on HD. These preliminary findings provide insight into the pre-transplantation period for patients and may aid our understanding of how to best protect patients against HHV-6 after transplantation.

    ♦ Purpose: Decline in physical function is commonly observed in patients with kidney failure on dialysis. Whether lung congestion, a predictable consequence of cardiomyopathy and fluid overload, may contribute to the low physical functioning of these patients has not been investigated. ♦ Methods: In 51 peritoneal dialysis (PD) patients, we investigated the cross-sectional association between the physical functioning scale of the Kidney Disease Quality of Life Short Form (KDQOL-SF: Rand Corporation, Santa Monica, CA, USA) and an ultrasonographic measure of lung water recently validated in dialysis patients. The relationship between physical functioning and lung water was also analyzed taking into account the severity of dyspnea measured using the New York Heart Association (NYHA) classification currently used to grade the severity of heart failure. ♦ Results: Evidence of moderate-to-severe lung congestion was evident in 20 patients, and this alteration was asymptomatic (that is, NHYHA class I) in 11 patients (55%). On univariate analysis, physical functioning was inversely associated with lung water (r = -0.48, p < 0.001), age (r = -0.44, p = 0.001), previous cardiovascular events (r = -0.46, p = 0.001), and fibrinogen (r = -0.34, p = 0.02). Physical functioning was directly associated with blood pressure, the strongest association being with diastolic blood pressure (r = 0.38, p = 0.006). The NYHA class correlated inversely with physical functioning (r = -0.51, p < 0.001). In multiple regression analysis, only lung water and fibrinogen remained independent correlates of physical functioning. The NYHA class failed to maintain its independent association. ♦ Conclusions: This cross-sectional study supports the hypothesis that symptomatic and asymptomatic lung congestion is a relevant factor in the poor physical functioning of patients on PD.

    Introduction Mortality in dialysis patients is higher than in the general population, and cardiovascular disease represents the leading cause of death. Hypertension and volume overload are important risk factors for the development of left ventricular hypertrophy (LVH) in hemodialysis (HD) and peritoneal dialysis (PD) patients. Other factors are mainly represented by hyperparathyroidism, vascular calcification, arterial stiffness and inflammation. The aim of this study was to compare blood pressure (BP) and metabolic parameters with cardiovascular changes [cardiothoracic ratio (CTR), aortic arch calcification (AAC) and LV mass index (LVMI)] between PD and HD patients. Materials and Methods 45 patients (23 HD and 22 PD patients) were enrolled. BP measurements, echocardiography and chest X-ray were performed in each patient to determine the LVMI and to evaluate the CTR and AAC. Inflammatory indexes, intact parathyroid hormone (iPTH) and arterial blood gas analysis were also evaluated. Results LVMI was higher in PD than HD patients (139 ŷ 19 vs. 104 ŷ 22; p = 0.04). In PD patients, a significant correlation between iPTH, C-reactive protein and the presence of LVH was observed (r = 0.70, p = 0.04; r = 0.70, p = 0.03, respectively). The CTR was increased in PD patients as compared to HD patients, while no significant differences in cardiac calcifications were determined. Conclusions Our data indicate that HD patients present more effective BP control than PD patients. Adequate fluid and metabolic control are necessary to assess the adequacy of BP, which is strongly correlated with the increase in LVMI and with the increased CTR in dialysis patients. PD is a home therapy and allows a better quality of life, but PD patients may present a further increased cardiovascular risk if not adequately monitored. PMID:25759697

    Phosphorus control is generally considered to be better in peritoneal dialysis (PD) patients as compared with haemodialysis (HD) patients. Predialysis phosphorus concentrations are misleading as a measure of phosphorus exposure in HD, as these neglect significant dialysis-related fluctuations. Parameters of mineral metabolism, including parathyroid hormone (PTH) and fibroblast growth factor-23 (FGF-23), were determined in 79 HD and 61 PD patients. In PD, phosphorus levels were determined mid-morning. In HD, time-averaged phosphorus concentrations were modelled from measurements before and after the mid-week dialysis session. Weekly renal, dialytic and total phosphorus clearances as well as total mass removal were calculated from urine and dialysate collections. Time-averaged serum phosphorus concentrations in HD (3.5 ± 1.0 mg/dL) were significantly lower than the mid-morning concentrations in PD (5.0 ± 1.4 mg/dL, P < 0.0001). In contrast, predialysis phosphorus concentrations (4.6 ± 1.4 mg/dL) were not different from PD. PTH and FGF-23 levels were significantly higher in PD. Despite higher residual renal function, total phosphorus clearance was significantly lower in PD (P < 0.0001). Total phosphorus mass removal, conversely, was significantly higher in PD (P < 0.05). Our data suggest that the time-averaged phosphorus concentrations in patients treated with PD are higher as compared with patients treated with HD. Despite a better preserved renal function, total phosphorus clearance is lower in patients treated with PD. Additional studies are needed to confirm these findings in a population with a different demographic profile and dietary background and to define clinical implications. © The Author 2016.

    To observe the effect of icodextrin on peritoneal membrane angiogenesis in continuous ambulatory peritoneal dialysis (CAPD) patients. This was a randomized double-blind perspective study of CAPD patients at our center between January 2006 to December 2006. The patients were randomized to receive either 7.5% icodextrin (ICO, n = 27) or glucose (GLU, n = 27) solution at night for 4 weeks. Peritoneal membrane function was defined as dialysate dwell for 4 hours to plasma ratio of creatinine (4 h D/Pcr) at baseline. Ultrafiltration volume, creatinine clearance (Ccr), VEGF and IL-6 in peritoneal effluent during the long night dwell (UF) dialysate were measured at baseline and after 4 weeks. The VEGF appearance was used to adjust the influences of dwell time and ultrafiltration volume. A total of 54 patients were enrolled. The baseline conditions showed no difference between the groups. After 2 and 4 weeks of therapy, both net UF and peritoneal creatinine clearance of long dwell were significantly higher in the ICO group than the GLU group. VEGF in night dwell PD solution was positively correlated with D/PCr (r = 0.68, P < 0.01)and negatively correlated to 4 hour ultrafiltration volume (r = -0.51, P < 0.01). The VEGF appearance was comparable between two groups at baseline. After a follow-up of 4 weeks, the VEGF appearance had an increasing tendency in the GLU group and a decreasing tendency in the ICO group but there was no significant difference. The ΔVEGF appearance (VEGF appearance in 4 week-VEGF appearance at baseline) was different between the GLU and ICO groups (9.5 ± 20.2 vs -13.4 ± 26.1, P < 0.01). IL-6 in night dwell dialysate had no difference between two groups. As compared with glucose-based solution, 7.5% icodextrin significantly decreases the local VEGF level in dialysate.

  20. How automated peritoneal dialysis is applied and maintained in Japan.

    According to a nationwide statistical survey in Japan, only 9,858 patients (3.3% of dialysis patients) were on maintenance peritoneal dialysis (PD) at the end of 2009. In this survey, 8,635 patients answered questions about the PD method, while 1,223 patients did not respond. In Japan, at the end of 2009, 5,143 patients (59.6%) on PD were treated with CAPD and 3,492 patients (40.4%) on PD were treated with automated PD (APD). It is well known that around 20% of Japanese PD patients choose to apply and maintain PD + HD combination therapy. The number of PD + HD patients (1,569) accounted for 20.7% of the PD-treated patients (7,591). In Japan, patients with fluid overloading preferably select PD + HD combination therapy with or without icodextrin use. Young patients select APD while patients on PD suffered from fluid overloading with high transporter membrane. What then are the factors that effect APD selection in Japan? The use of various forms of APD has increased considerably in the past few years. Important factors that contribute to APD selection are better adjustment of APD to the patient's lifestyle and the flexibility that APD offers to patients. In addition, patients with APD will be able to have good quality of life (QOL). Young patients on PD select APD because of good QOL. It is well known that almost all of children younger than 19 years with end-stage renal disease (ESRD) are undergoing APD. APD has a pivotal role in the management of pediatric patients with ESRD. Children on APD had a lower incidence of peritonitis compared with those with CAPD. The switch from CAPD to APD resulted in better ultrafiltration, less edema, lower mean arterial blood pressure, lower peritonitis rate and fewer hospital admissions. As in young patients, APD is also good method to select in elderly patients on PD. The need for the exchange to be performed by another person is increased in elderly and handicapped ESRD patients, however APD therapy is a good selection for them

    With increasing emphasis on expanding home-based dialysis, there is a need to understand adherence outcomes. This study set out to examine the prevalence and predictors of nonadherence among patients undergoing peritoneal dialysis. A cross sectional sample of 201 peritoneal dialysis patients recruited between 2010–2011 from Singapore General Hospital completed measures of quality of life, medication beliefs, self-efficacy and emotional distress. Nonadherence rates were high; 18% for dialysis, 46% for medication and 78% for diet. Intentional nonadherence was more common for dialysis (p = .03), whereas unintentional nonadherence was more common for medication (p = .002). Multivariate models indicated significant associations for higher education (intermediate vs low OR = 3.18, high vs low OR = 4.70), lower environment quality of life (OR = 0.79), dialysis self-efficacy (OR = 0.80) with dialysis nonadherence; higher education (OR = 2.22), self-care peritoneal dialysis (OR = 3.10), perceived necessity vs concerns over medication (OR = 0.90), self-efficacy (OR = 0.76) with nonadherence to medication. The odds for nonadherence to diet were higher among patients who were younger (OR = 0.96), of Chinese ethnicity (OR = 2.99) and those reporting better physical health (OR = 1.30) and lower self-efficacy (OR = 0.49). Nonadherence is common in peritoneal dialysis. Self-efficacy and beliefs about medication are promising targets for interventions designed to improve adherence. PMID:26919323

    Peritoneal dialysis peritonitis and fluid overhydration (OH) are frequent problems in peritoneal dialysis. The latter can cause gut wall oedema or be associated with malnutrition. Both may lead to increased peritonitis risk. We wished to determine if OH is an independent risk factor for peritonitis (caused by enteric organisms). Retrospectively study of patients with >2 bioimpedance assessments (Body Composition Monitor). We compared peritonitis rates of patients with above or below the median time-averaged hydration parameter (OH/extracellular water, OH/ECW). Multivariate analysis was performed to determine independent risk factors for peritonitis by enteric organism. We studied 580 patients. Peritonitis was experienced by 28% patients (followed up for an average of 17 months). The overall peritonitis rate was 1:34 patient months. Patients with low OH/ECW values had significantly lower rates of peritonitis from enteric organisms than overhydrated patients (incident rate ratio 1.53, 95% confidence interval 1.38-1.70, P < 0.001). Hydration remained an independent predictor of peritonitis from enteric organisms when multivariate model included demographic parameters (odds ratio for a 1% increment of OH/ECW was 1.05; 95% confidence interval 1.01-1.10, P < 0.02). However, including biochemical parameters of malnutrition reduced the predictive power of overhydration. We found an association between overhydration and increased rates of peritonitis. While this may partly be due to the high co-morbidity of patients (advanced age and diabetes), on multivariate analysis, only inclusion of nutritional parameters reduced this association. It remains to be determined if overhydration will prove to be a modifiable risk factor for peritonitis or whether malnutrition will prove to be more important. © 2015 Asian Pacific Society of Nephrology.

    Peritoneal dialysis-associated peritonitis (PD-associated peritonitis) could influence the outcome of PD patients, including technique survival. Although the use of the twin-bag system has decreased the incidence of peritonitis, the effects of biocompatible PD solutions are controversial. Additionally, since both infection-causing microorganisms and antimicrobial therapies have changed over time, the duration of treatment of peritonitis (the duration of peritonitis) seems to have changed. The study included 527 patients who received PD between January 1980 and December 2012 at a single center. We divided patients undergoing PD into three groups according to the type of PD system used, namely single-bag and conventional PD solutions (S+C group, N = 145), twin-bag and conventional PD solutions (T+C group, N = 171) and twin-bag and biocompatible PD solutions (T+B group, N = 211), and analyzed PD-associated peritonitis incidences. Incidences of PD-associated peritonitis (times per patient-months) and peritonitis-free time were 1/59.4, 1/70.6 and 1/103.1, and 52, 97, and 100 months for the S+C, T+C and T+B groups, respectively. The duration of peritonitis, has thus, become dramatically shorter in recent years. Streptococcus sp. were associated with shortest and fungi with longest durations of peritonitis. Staphylococcus sp. and Pseudomonas aeruginosa were predominant in the S+C group. The twin-bag system has made a greater contribution to reductions in PD-associated peritonitis than biocompatible PD solutions. Furthermore, changes in microorganisms, antimicrobial therapies, patient education and improved PD system devices have presumably affected the reduction in the duration of peritonitis. © 2015 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    The aim of the study was to explore renal nurses' experiences, strategies and challenges with regard to the patient education process in peritoneal dialysis. Patient education in peritoneal dialysis is essential to developing a successful home-based peritoneal dialysis program. In this area research is scarce and there is a particular lack of focus on the perspective of the renal nurse. Qualitative design formed by thematic qualitative text analysis. Five group interviews (n = 20) were used to explore the challenges peritoneal dialysis nurses face and the training strategies they use. The interviews were analyzed with thematic qualitative content analysis using deductive and inductive subcategory application. The findings revealed the education barriers perceived by nurses that patients may face. They also showed that using assessment tools is important in peritoneal dialysis patient education, as is developing strategies to promote patient self-management. There is a need for a deeper understanding of affective learning objectives, and existing teaching activities and materials should be revised to incorporate the patient's perspective. Patients usually begin having questions about peritoneal dialysis when they return home and are described as feeling overwhelmed. Adapting existing conditions is considered a major challenge for patients and nurses. The results provided useful insights into the best approaches to educating peritoneal dialysis patients and served to raise awareness of challenges experienced by renal nurses. Findings underline the need for nosogogy - an approach of teaching adults (andragogy) with a chronic disease. Flexibility and cooperation are competencies that renal nurses must possess. Still psychomotor skills dominate peritoneal dialysis patient training, there is a need of both a deeper understanding of affective learning objectives and the accurate use of (self-)assessment tools, particularly for health literacy. © 2016 John Wiley & Sons

    Among women with chronic kidney disease, successful pregnancy with a surviving infant is rather rare. Although these pregnancies carry higher risk, with the possibility of adverse maternal and fetal outcomes, they can be managed with close monitoring and intense renal replacement therapy. Given the hemodynamic advantages of peritoneal dialysis over hemodialysis in pregnancy, peritoneal dialysis therapy is thought to be a favorable renal replacement option in pregnant patients with chronic kidney disease.

    Icodextrin, a glucose polymer, is widely used as an alternative to glucose as the osmotic agent in peritoneal dialysis (PD). We describe a case of a continuous ambulatory peritoneal dialysis patient who developed severe cutaneous hypersensitivity after initiation of icodextrin PD solution. Erythematous skin lesions gradually disappeared after discontinuation of icodextrin PD solution. Although the safety and efficacy of icodextrin PD solution is well documented, clinicians should be mindful of the possibility of severe adverse cutaneous reactions to icodextrin PD solution.

    ♦ Background: Although several studies have demonstrated the economic advantages of peritoneal dialysis (PD) over hemodialysis (HD), few reports in the literature have compared the costs of HD and PD access. The aim of the present study was to compare the resources required to establish and maintain the dialysis access in patients who initiated HD with a tunneled cuffed catheter (TCC) or an arteriovenous fistula (AVF) and in patients who initiated PD. ♦ Methods: We retrospectively analyzed the 152 chronic kidney disease patients who consecutively initiated dialysis treatment at our institution in 2008 (HD-AVF, n = 65; HD-CVC, n = 45; PD, n = 42). Detailed clinical and demographic information and data on access type were collected for all patients. A comprehensive measure of total dialysis access costs, including surgery, radiology, hospitalization for access complications, physician costs, and transportation costs was obtained at year 1 using an intention-to-treat approach. All resources used were valued using 2010 prices, and costs are reported in 2010 euros. ♦ Results: Compared with the HD-AVF and HD-TCC modalities, PD was associated with a significantly lower risk of access-related interventions (adjusted rate ratios: 1.572 and 1.433 respectively; 95% confidence intervals: 1.253 to 1.891 and 1.069 to 1.797). The mean dialysis access-related costs per patient-year at risk were €1171.6 [median: €608.8; interquartile range (IQR): €563.1 - €936.7] for PD, €1555.2 (median: €783.9; IQR: €371.4 - €1571.7) for HD-AVF, and €4208.2 (median: €1252.4; IQR: €947.9 - €2983.5) for HD-TCC (p < 0.001). In multivariate analysis, total dialysis access costs were significantly higher for the HD-TCC modality than for either PD or HD-AVF (β = -0.53; 95% CI: -1.03 to -0.02; and β = -0.50; 95% CI: -0.96 to -0.04). ♦ Conclusions: Compared with patients initiating HD, those initiating PD required fewer resources to establish and maintain a dialysis

Compared with the HD-AVF and HD-TCC modalities, PD was associated with a significantly lower risk of access-related interventions (adjusted rate ratios: 1.572 and 1.433 respectively; 95% confidence intervals: 1.253 to 1.891 and 1.069 to 1.797). The mean dialysis access-related costs per patient-year at risk were €1171.6 [median: €608.8; interquartile range (IQR): €563.1 - €936.7] for PD, €1555.2 (median: €783.9; IQR: €371.4 - €1571.7) for HD-AVF, and €4208.2 (median: €1252.4; IQR: €947.9 - €2983.5) for HD-TCC (p < 0.001). In multivariate analysis, total dialysis access costs were significantly higher for the HD-TCC modality than for either PD or HD-AVF (β = -0.53; 95% CI: -1.03 to -0.02; and β = -0.50; 95% CI: -0.96 to -0.04). Compared with patients initiating HD, those initiating PD required fewer resources to establish and maintain a dialysis access during the first year of treatment.

    Peritoneal dialysis (PD) or conventional hemodialysis (HD) are considered to be equally efficient dialysis methods in children and adolescents. The aim of our study was to analyze whether an intensified, nocturnal HD program (NHD) is superior to PD in an adolescent cohort. Thirteen patients were prospectively enrolled in a NHD program. We measured uremia-associated parameters, parameters for nutrition, medication and blood pressure and analyzed the data. These data were compared to those of 13 PD controls, matched for gender, age and weight at the beginning the respective dialysis program and after 6 months of treatment. Serum phosphate levels decreased significantly in the NHD group and remained unchanged in the PD group. Arterial blood pressure in the NHD was significantly lower despite the reduction of antihypertensive treatment, whereas blood pressure levels remained unchanged in the PD controls. Preexisting left ventricular hypertrophy resolved and albumin levels improved with NHD. Dietary restrictions could be lifted for those on NHD, whereas they remained in place for the patients on PD treatment. Residual diuresis remained unchanged after 6 months of either NHD or PD. NHD patients experienced fewer days of hospitalization than the PD controls. Based on our results, NHD results in significantly improved parameters of uremia and nutrition. If individually and logistically possible, NHD should be the treatment modality of preference for older children and adolescents.

    ♦ Objective: Peritoneal dialysis (PD) has become more prevalent as a treatment modality for end-stage renal disease, and peritonitis remains one of its most devastating complications. The aim of the present investigation was to examine the frequency and predictors of peritonitis and the impact of peritonitis on clinical outcomes. ♦ Methods: Our retrospective observational cohort study enrolled 391 patients who had been treated with continuous ambulatory PD (CAPD) for at least 90 days. Relevant demographic, biochemical, and clinical data were collected for an analysis of CAPD-associated peritonitis, technique failure, drop-out from PD, and patient mortality. ♦ Results: The peritonitis rate was 0.196 episodes per patient-year. Older age (>65 years) was the only identified risk factor associated with peritonitis. A multivariate Cox regression model demonstrated that technique failure occurred more often in patients experiencing peritonitis than in those free of peritonitis (p < 0.001). Kaplan-Meier analysis revealed that the group experiencing peritonitis tended to survive longer than the group that was peritonitis-free (p = 0.11). After multivariate adjustment, the survival advantage reached significance (hazard ratio: 0.64; 95% confidence interval: 0.46 to 0.89; p = 0.006). Compared with the peritonitis-free group, the group experiencing peritonitis also had more drop-out from PD (p = 0.03). ♦ Conclusions: The peritonitis rate was relatively low in the present investigation. Elderly patients were at higher risk of peritonitis episodes. Peritonitis independently predicted technique failure, in agreement with other reports. However, contrary to previous studies, all-cause mortality was better in patients experiencing peritonitis than in those free of peritonitis. The underlying mechanisms of this presumptive “peritonitis paradox” remain to be clarified. PMID:24084840

    We compared the proteome profile of peritoneal effluents obtained with icodextrin (Ico) or glucose (Glu) in paediatric patients and defined the oxido-redox status of proteins. Sixteen patients underwent two 14-h daytime dwells performed on subsequent days with 7.5% Ico and 3.86% Glu solutions. Protein composition was analysed by two-dimensional electrophoresis and mass spectrometry; oxidized products were evaluated by cyanine labelling. Peritoneal transport kinetics of β2-microglobulin and cystatin C was linear for both solutions, but was significantly higher with Ico than with Glu, suggesting a better efficiency for these molecules. There was a linear correlation between total protein removal during Ico and Glu dialysis in the same patient, suggesting that it is a function of peritoneal membrane characteristics. The ratio between proteins removed by Ico and by Glu solutions was higher at low removal rate. Image gel analysis revealed 1064 and 774 spots, respectively, in Ico and Glu solutions; 524 were common, and 314 were higher in Ico than Glu effluents. Analysis of protein oxido-redox status showed a greater amount of oxidized albumin in Ico dialysate that was correlated with lower serum levels. Our results indicate a better efficiency of Ico in removing small proteins. Removal of big proteins and their oxidized isoforms reflects potentially opposite effects. The long-term clinical consequences of removing also potentially important molecules are to be defined.

    We evaluated differences in individual peritoneal membrane transport function and nutritional status in patients with diabetes mellitus (DM) and nondiabetic (non-DM) patients on continuous ambulatory peritoneal dialysis (CAPD). We used a newly developed peritoneal function test, personal dialysis capacity, in 88 patients (44 DM and 44 non-DM) on CAPD for 1 to 210 months. Sex, age, past history of peritonitis, and duration of CAPD were matched in DM and non-DM patients. Serum albumin (mean +/- SEM) was lower in DM compared with non-DM patients: 3.0 +/- 0.1 g/dL (30 +/- 1 g/L) versus 3.5 +/- 0.1 g/dL (35 +/- 1 g/L), P < 0.001. Peritoneal area and dialysis protein loss were greater in DM versus non-DM patients. In multiple linear regression analysis, the only independent predictor of serum albumin in patients with DM was dialysis protein loss. In contrast, age, past history of peritonitis, duration of CAPD, caloric intake, protein nitrogen appearance and protein catabolic rate, and residual renal function did not correlate with serum albumin in DM patients. In non-DM patients, age, duration of CAPD, and past history of peritonitis, but not dialysis protein loss, were independent predictors of serum albumin. There was a significant correlation in DM patients, but not in non-DM CAPD patients, between dialysis protein loss and urinary excretion of protein (r = 0.866, P = 0.0005). In this multicenter study, peritoneal membrane transport and peritoneal protein permeability were significantly higher in DM than in non-DM patients. Hypoproteinemia in DM patients is attributable to the high permeability of the peritoneal membrane undergoing CAPD. Copyright 2002 by the National Kidney Foundation, Inc.

  13. Skin Autofluorescence and Mortality in Patients on Peritoneal Dialysis

    2015-01-01

    Abstract Skin autofluorescence (SAF) is a proven prognostic factor of mortality in hemodialysis patients. Traditional and nontraditional risk factors are almost equivalent in peritoneal dialysis (PD), and cardiovascular disease (CVD) is the leading cause of death. Moreover, peritoneal glucose absorption accelerates the degenerative processes of connective tissues as in diabetes. In our study, we examined the predictive value of SAF for total mortality in the PD population. Data were collected from 198 prevalently adult Caucasian PD patients. One hundred twenty-six patients (mean age 66.2 y, men [n = 73], diabetes ratio 75/126) had anamnestic CVD (coronary heart disease, cerebrovascular disease, peripheral arterial disease). Initially, we evaluated factors affecting SAF and CVD by multivariate linear regression. Survival rates were estimated by recording clinical and demographic data associated with mortality during a 36-month follow-up using the Kaplan–Meier method. Analyses were further stratified based on the presence or absence of CVD and SAF levels above or below the upper tercile 3.61 arbitrary units. Skin autofluorescence was influenced by CVD (P < 0.01, 95% confidence interval [CI] 0.1–0.5) and white blood cell counts (P < 0.001, 95% CI 0.031–0.117). According to the Spearman correlation, SAF correlated with peritoneal cumulative glucose exposure (P = 0.02) and elapsed time in PD (P = 0.008). CVD correlated with age (P < 0.001, 95% CI 1.24–1.65) and diabetes (P < 0.001, 95% CI 2.58–10.66). More deaths were observed in the high SAF group than in the low SAF group (34/68 vs 44/130; P = 0.04). Comparing the CVD(−) low SAF group survival (mean 33.9 mos, standard error [SE] 1.39) to CVD(+) low SAF (mean 30.5 mos, SE 1.37, P = 0.03) and to CVD(+) high SAF group (mean 27.1 mos, SE 1.83, P = 0.001), the difference was significant. In conclusion, among PD patients, SAF values over 3.61 arbitrary units seem to be a

    ♦ Introduction: Peritoneal dialysis fluids (PDF) differ with respect to osmotic and buffer compound, and pH and glucose degradation products (GDP) content. The impact on peritoneal membrane integrity is still insufficiently described. We assessed global genomic effects of PDF in primary human peritoneal mesothelial cells (PMC) by whole genome analyses, quantitative real-time polymerase chain reaction (RT-PCR) and functional measurements. ♦ Methods: PMC isolated from omentum of non-uremic patients were incubated with conventional single chamber PDF (CPDF), lactate- (LPDF), bicarbonate- (BPDF) and bicarbonate/lactate-buffered double-chamber PDF (BLPDF), icodextrin (IPDF) and amino acid PDF (APDF), diluted 1:1 with medium. Affymetrix GeneChip U133Plus2.0 (Affymetrix, CA, USA) and quantitative RT-PCR were applied; cell viability was assessed by proliferation assays. ♦ Results: The number of differentially expressed genes compared to medium was 464 with APDF, 208 with CPDF, 169 with IPDF, 71 with LPDF, 45 with BPDF and 42 with BLPDF. Out of these genes 74%, 73%, 79%, 72%, 47% and 57% were downregulated. Gene Ontology (GO) term annotations mainly revealed associations with cell cycle (p = 10-35), cell division, mitosis, and DNA replication. One hundred and eighteen out of 249 probe sets detecting genes involved in cell cycle/division were suppressed, with APDF-treated PMC being affected the most regarding absolute number and degree, followed by CPDF and IPDF. Bicarbonate-containing PDF and BLPDF-treated PMC were affected the least. Quantitative RT-PCR measurements confirmed microarray findings for key cell cycle genes (CDK1/CCNB1/CCNE2/AURKA/KIF11/KIF14). Suppression was lowest for BPDF and BLPDF, they upregulated CCNE2 and SMC4. All PDF upregulated 3 out of 4 assessed cell cycle repressors (p53/BAX/p21). Cell viability scores confirmed gene expression results, being 79% of medium for LPDF, 101% for BLPDF, 51% for CPDF and 23% for IPDF. Amino acid-containing PDF

    To study the perceived illness intrusion of continuous ambulatory peritoneal dialysis (CAPD) patients, to examine their demographics, and to find out the association among demographics, duration of illness as well as illness intrusion, 40 chronic kidney disease stage V patients on CAPD during 2006-2007 were studied. Inclusion criteria were patients' above 18 years, willing, stable, and completed at least two months of dialysis. Those with psychiatric co-morbidity were excluded. Sociodemographics were collected using a semi-structured interview schedule. A 14-item illness intrusion checklist covering various aspects of life was administered. The subjects had to rate the illness intrusion in their daily life and the extent of intrusion. The data was analyzed using descriptive statistics and chi square test of association. The mean age of the subjects was 56.05 ± 10.05 years. There was near equal distribution of gender. 82.5% were married, 70.0% belonged to Hindu religion, 45.0% were pre-degree, 25.0% were employed, 37.5% were housewives and 30.0% had retired. 77.5% belonged to the upper socioeconomic strata, 95.0% were from an urban background and 65.0% were from nuclear families. The mean duration of dialysis was 19.0 ± 16.49 months. Fifty-eight percent of the respondents were performing the dialysis exchanges by themselves. More than 95.0%were on three or four exchanges per day. All the 40 subjects reported illness intrusion in their daily life. Intrusion was perceived to some extent in the following areas: health 47.5%, work 25.0%, finance 37.5%, diet 40.0%, and psychological 50.0%. Illness had not intruded in the areas of relationship with spouse 52.5%, sexual life 30.0%, with friends 92.5%, with family 85.5%, social functions 52.5%, and religious functions 75.0%. Statistically significant association was not noted between illness intrusion and other variables. CAPD patients perceived illness intrusion to some extent in their daily life. Elderly, educated

    We aimed to clarify arteriosclerotic risk and to document possible relationships between cardiovascular risk factors and echocardiographic parameters in paediatric peritoneal dialysis (PD) patients. M-mode/Doppler/tissue Doppler echocardiographic studies and lipid/lipoproteins, homocysteine, high-sensitivity C-reactive protein (HS-CRP) levels and carotid intima-media thickness (CIMT) were determined in 59 patients (age: 14.2 +/- 4.5 years) and in 36 healthy subjects. Structural and functional cardiac abnormalities were observed in patients on maintenance dialysis. Increased left ventricular mass index (LVMI, P = 0.000), relative wall thickness (P = 0.000), myocardial performance index (MPI, P = 0.000) were documented in the patients. Lipoprotein (a) (P = 0.000), homocysteine (P = 0.001), HS-CRP (P = 0.000) and CIMT (P = 0.000) were significantly elevated in the patients. Left ventricular hypertrophy (LVH) was prevalent in 68% of the patients. Patients with LVH had higher levels of HS-CRP (P = 0.001) and CIMT (P = 0.028) than those without LVH. Haemoglobin was an independent predictor of LVMI (beta: -8.9, P = 0.001), while residual diuresis and CIMT were independent predictors of diastolic dysfunction (beta: -0.45, P = 0.034 and beta: 5.90, P = 0.008, respectively). Albumin (beta: -0.72, P = 0.018) and Kt/V urea (beta: -0.48, P = 0.012) were significant predictors of CIMT. There were positive correlations between LVMI and CIMT. HS-CRP was positively correlated with LVMI as well as CIMT. Elevated levels of atherosclerotic/ inflammatory risk factors, low haemoglobin levels and loss of residual renal function and their negative effects on heart are of remarkable importance in paediatric patients on maintenance peritoneal dialysis. Achieving recommended targets for haemoglobin, blood pressure and Kt/V urea, preserving residual renal function as well as managing inflammation and subsequent arteriosclerosis is obviously essential to improve the patients' prognosis.

    Background and objectives Assisted peritoneal dialysis is a treatment option for individuals with barriers to self-care who wish to receive home dialysis, but previous research suggests that this treatment modality is associated with a higher rate of hospitalization. The objective of our study was to determine whether assisted peritoneal dialysis has a different rate of hospital days compared to in-center hemodialysis. Design, setting, participants, & measurements We conducted a multicenter, retrospective cohort study by linking a quality assurance dataset to administrative health data in Ontario, Canada. Subjects were accrued between January 1, 2004 and July 9, 2013. Individuals were grouped into assisted peritoneal dialysis (family or home care assisted) or in-center hemodialysis on the basis of their first outpatient dialysis modality. Inverse probability of treatment weighting using a propensity score was used to create a sample in which the baseline covariates were well balanced. Results The study included 872 patients in the in–center hemodialysis group and 203 patients in the assisted peritoneal dialysis group. Using an intention to treat approach, patients on assisted peritoneal dialysis had a similar hospitalization rate of 11.1 d/yr (95% confidence interval, 9.4 to 13.0) compared with 12.9 d/yr (95% confidence interval, 10.3 to 16.1) in the hemodialysis group (P=0.19). Patients on assisted peritoneal dialysis were more likely to be hospitalized for dialysis-related reasons (admitted for 2.4 d/yr [95% confidence interval, 1.8 to 3.2] compared with 1.6 d/yr [95% confidence interval, 1.1 to 2.3] in the hemodialysis group; P=0.04). This difference was partly explained by more hospital days because of peritonitis. Modality switching was associated with high rates of hospital days per year. Conclusions Assisted peritoneal dialysis was associated with similar rates of all-cause hospitalization compared with in-center hemodialysis. Patients on assisted

    Peritoneal dialysis as a mode of renal replacement therapy still has not been embraced widely as an alternative to hemodialysis. Furthermore, there is marked variability in peritoneal dialysis catheter insertion techniques and perioperative management within the United States. After the publication of best-demonstrated practices for peritoneal dialysis catheter placement, the utilization of peritoneal dialysis has increased significantly at our institution. We detail the long-term success of peritoneal dialysis catheter placement after the adoption of best-demonstrated practices. Retrospective chart review was performed on all patients who underwent laparoscopic peritoneal dialysis catheter placement using the best-demonstrated practice technique from January 2005 through December 2015. Preoperative patient demographic information, intraoperative variables, 30-day morbidity and mortality, and long-term catheter durability outcomes were investigated. A total of 457 patients met inclusion criteria. Four (0.9%) patients experienced an immediate postoperative complication requiring return to the operating room. There were no perioperative mortalities. A total of 298 (65.2%) patients were available for long-term follow-up; 221 (74.2%) patients are still alive, 76 (25.6%) patients are still undergoing peritoneal dialysis, 63 (21.1%) patients transitioned from peritoneal dialysis to hemodialysis, and 88 (29.5%) patients have undergone kidney transplantation. Based on Kaplan-Meier survival plots, 30% of patients will transition from peritoneal dialysis to hemodialysis after 5.5 years of peritoneal dialysis and the median time from commencing peritoneal dialysis to kidney transplantation is 5.6 years. Based on our institutional data, the adoption of best-demonstrated practices should provide long-term and reliable access to the peritoneal cavity. We recommend the adoption of these techniques to facilitate long-term peritoneal dialysis catheter survival. Copyright © 2017

    Peritonitis is a common complication in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD). In this retrospective study, peritonitis rates and patient survival of 180 patients on CAPD and 128 patients on APD were compared in the period from January 2005 to December 2014 at Al-Nafisi Center in Kuwait. All patients had prophylactic topical mupirocin at catheter exit site. Patients on CAPD had twin bag system with Y transfer set. The peritonitis rates were 1 in 29 months in CAPD and 1 in 38 months in APD (p < 0.05). Percentage of peritonitis free patients over 10-year period in CAPD and APD were 49 and 60%, respectively (p < 0.05). Time to develop peritonitis was 10.25 ± 3.1 months in CAPD compared to 16.1 ± 4 months in APD (p < 0.001). Relapse and recurrence rates were similar in both groups. Median patient survival in CAPD and APD groups with peritonitis was 13.1 ± 1 and 14 ± 1.4 months respectively (p = 0.3) whereas in peritonitis free patients it was 15 ± 1.4 months in CAPD and 23 ± 3.1 months in APD (p = 0.025). APD had lower incidence rate of peritonitis than CAPD. Patient survival was better in APD than CAPD in peritonitis free patients but was similar in patients who had peritonitis.

    A rare but severe complication, intestinal necrosis, has been reported after sodium polystyrene sulfonate (SPS; Kayexalate) and sorbitol intake. Some case reports described bowel perforation following calcium polystyrene sulfonate (CPS; Kalimate) administration. We report a case of ileum and colon perforation following peritoneal dialysis-related peritonitis and high-dose Kalimate in a 59-year-old female patient. The patient had a history of hypertension, diabetes mellitus, and end-stage renal disease (ESRD). During hospitalization for peritoneal dialysis-related peritonitis, she developed hyperkalemia, and Kalimate was administered orally. However, severe abdominal distension and pain occurred just one day after Kalimate intake. An urgent surgery disclosed several perforations in the ileum and sigmoid colon. Pathology of the resected gut showed transmural necrosis and perforation with basophilic angulated crystals. The patient finally expired during hospitalization due to refractory septic shock.

    In computer simulations, according to the three-pore model of peritoneal transport, neutralization of conventional acidic peritoneal dialysis fluids is predicted to produce an improved ultrafiLtration (UF). However, in a previous study, a two-compartment peritoneal dialysis system with a minimum of glucose degradation products (GDP), PD-Bio, having a pH of 6.3 and being conventionalLy lactate buffered, did not produce an increased UF. We tested a newly formulated, glucose-based, GDP-reduced solution, denoted "N" for "neutral," containing a mixture of lactate (30 mmol/L) and bicarbonate (10 mmol/L) as buffer system, and having a pH of 7.2. This new formulation was compared with Gambrosol trio (GT) (identical in composition to PD-Bio, but delivered in a three-compartment system; both by Gambro Lundia AB, Lund, Sweden) in an open, prospective controlled study of 13 patients. Each of the 13 patients used GT for 14 days, followed by 14 days of N. All bags were weighed on a digital scale before instillation and after drainage to assess the UF in each dwell (and during 24 hours). Glucose concentration in each bag was noted. In the morning and night dwells, dialysis fluid glucose concentration was standardized to 2.5%. Body weight was measured every morning (empty abdomen). In the middle of each 14-day period, a 4-hour standardized ("study day") dwell was performed, using 125I-albumin (RISA) as volume marker, during which blood and dialysate samples were taken repeatedly and anaLyzed for RISA, creatinine, urea, phosphate, glucose, standard bicarbonate, lactate, and pH. The permeability surface area product (PS) for small solutes (and A0/deltaX; "area parameter") was calculated. Clearance (Cl) of RISA to plasma (P) (C-->P), "direct lymphatic absorption," and total Cl of RISA out of the peritoneal cavity (Cl(out)) were also determined. The 13 patients using N, compared to GT, displayed an increased daily UF, the difference being 233 mL (p < 0.05). The pH values of N were

    Background and objectives Home dialysis is often recognized as a first-choice therapy for patients initiating dialysis. However, studies comparing clinical outcomes between peritoneal dialysis and home hemodialysis have been very limited. Design, setting, participants, & measurements This Australia and New Zealand Dialysis and Transplantation Registry study assessed all Australian and New Zealand adult patients receiving home dialysis on day 90 after initiation of RRT between 2000 and 2012. The primary outcome was overall survival. The secondary outcomes were on-treatment survival, patient and technique survival, and death-censored technique survival. All results were adjusted with three prespecified models: multivariable Cox proportional hazards model (main model), propensity score quintile–stratified model, and propensity score–matched model. Results The study included 10,710 patients on incident peritoneal dialysis and 706 patients on incident home hemodialysis. Treatment with home hemodialysis was associated with better patient survival than treatment with peritoneal dialysis (5-year survival: 85% versus 44%, respectively; log-rank P<0.001). Using multivariable Cox proportional hazards analysis, home hemodialysis was associated with superior patient survival (hazard ratio for overall death, 0.47; 95% confidence interval, 0.38 to 0.59) as well as better on-treatment survival (hazard ratio for on-treatment death, 0.34; 95% confidence interval, 0.26 to 0.45), composite patient and technique survival (hazard ratio for death or technique failure, 0.34; 95% confidence interval, 0.29 to 0.40), and death-censored technique survival (hazard ratio for technique failure, 0.34; 95% confidence interval, 0.28 to 0.41). Similar results were obtained with the propensity score models as well as sensitivity analyses using competing risks models and different definitions for technique failure and lag period after modality switch, during which events were attributed to the

    Health care organizations must respond quickly to today's volatile and changing environment. This article describes how St. Michael's Hospital (acute care hospital) and the Drs. Paul and John Rekai Centre (long-term care facility) collaborated to use an innovative approach to address pressures of change affecting peritoneal dialysis (PD) care delivery for the elderly. The collaborative applied Galpin's (1996) nine-stage Change Management Model to implement the organizational change. Both organizations generated a shared vision to improve timely access to nursing homes for patients requiring both placement and ongoing peritoneal dialysis. They analyzed their current status and committed resources for the collaboration. Both organizations generated general and detailed recommendations for PD care delivery processes. A pilot was implemented and refinement of the collaboration occurred prior to formal roll out. This application of a change management model to establish organizational partnership may be of interest to those seeking to establish similar collaborations.

    Background Calciphylaxis is a rare but devastating condition in end-stage renal disease (ESRD) patients. Most research in the field of calciphylaxis is focused on hemodialysis (HD) patients; however, data on calciphylaxis incidence, risk factors, and mortality in peritoneal dialysis (PD) patients are limited. Methods In this cohort study, we examined data from adult patients who initiated PD for ESRD management at our institute’s PD unit from January 2001 to December 2015. Associations with the development of calciphylaxis were examined for clinical, laboratory, and medication exposures. Incidence of calciphylaxis and mortality in PD patients who developed calciphylaxis were analyzed. Treatments administered to treat calciphylaxis in PD patients were summarized. Results In this cohort of 63 patients, 7 patients developed calciphylaxis (incidence rate: 9.0 per 1,000 patient-years). Median age of PD patients who developed calciphylaxis was 50 years, 57% were white, 71% females, and 71% were previously on HD. Female sex, obesity, HD as a prior dialysis modality, recurrent hypotension, elevated time-averaged serum phosphorous levels, reduced time-averaged serum albumin levels, and warfarin therapy were associated with increased calciphylaxis risk in univariate logistic regression analyses. Intravenous sodium thiosulfate was administered in 57% of PD patients who developed calciphylaxis. One-year mortality in PD patients who developed calciphylaxis was 71% despite multimodal treatment including sodium thiosulfate, hyperbaric oxygen, cinacalcet, and wound debridement. Conclusion Calciphylaxis is a rare but frequently fatal condition in PD patients. Our study provides critical early insights into calciphylaxis incidence, risk factors, and prognosis in PD patients. Sample size and characteristics of patients included in our study limit generalizability to overall PD population and warrant examination in larger independent studies. PMID:27698566

    AIM: To examine all skin changes in peritoneal dialysis (PD) patients followed up in our unit. METHODS: Patients on PD program for at least three months without any known chronic skin disease were included in the study. Patients with already diagnosed skin disease, those who have systemic diseases that may cause skin lesions, patients with malignancies and those who did not give informed consent were excluded from the study. All patients were examined by the same predetermined dermatologist with all findings recorded. The demographic, clinical and laboratory data including measures of dialysis adequacy of patients were recorded also. Statistical Package for Social Sciences (SPSS) for Windows 16.0 standard version was used for statistical analysis. RESULTS: Among the patients followed up in our PD unit, those without exclusion criteria who gave informed consent, 38 patients were included in the study with male/female ratio and mean age of 26/12 and 50.3 ± 13.7 years, respectively. The duration of CKD was 7.86 ± 4.16 years and the mean PD duration was 47.1 ± 29.6 mo. Primary kidney disease was diabetic nephropathy in 11, nephrosclerosis in six, uropathologies in four, chronic glomerulonephritis in three, chronic pyelonephritis in three, autosomal dominant polycystic kidney disease in three patients while cause was unknown in eight patients. All patients except for one patient had at least one skin lesion. Loss of lunula, onychomycosis and tinea pedis are the most frequent skin disorders recorded in the study group. Diabetic patients had tinea pedis more frequently (P = 0.045). No relationship of skin findings was detected with primary renal diseases, comorbidities and medications that the patients were using. CONCLUSION: Skin abnormalities are common in in PD patients. The most frequent skin pathologies are onychomycosis and tinea pedis which must not be overlooked. PMID:27458566

    ♦ Background: End-stage renal disease patients have significant cardiovascular morbidity and mortality, but little is known about differences in coagulation profiles between patients on hemodialysis (HD) and on peritoneal dialysis (PD). Given their long-term exposure to glucose-based dialysate, patients on PD can experience metabolic derangements. Theoretically, that exposure should create a more prothrombotic environment than occurs in HD patients. The objective of the present study was to quantify potential differences in baseline coagulation between PD and HD patients. ♦ Methods: Our single-center cross-sectional study at a large academic health science center enrolled 50 age-, race-, and sex-matched subjects (10 control subjects, 20 HD patients, and 20 PD patients). Measurements included platelet function, platelet receptor distribution, and coagulation dynamics by thromboelastography and Hemodyne hemostasis assay (Hemodyne, Richmond, VA, USA). ♦ Results: Compared with healthy control subjects, patients on both forms of dialysis showed prothrombotic coagulation protein profiles. The tissue-factor pathway was markedly elevated in both groups, but PD was associated with significantly greater concentrations of tissue factor (p = 0.0056) and tissue-factor pathway inhibitor (p = 0.0138). Similarly, compared with patients receiving HD, patients on PD had greater concentrations of fibrinogen (p = 0.0325), which corresponded with platelet hyperfunction as measured by platelet contractile force and clot elastic modulus (p = 0.003 and 0.017 respectively, compared with values in HD patients). Platelet receptor distribution was similar between the groups. ♦ Conclusions: Compared with patients on HD, patients on PD appear to have a more prothrombotic profile. The clinical relevance of these findings needs to be studied in a prospective manner. PMID:24293664

    ♦ Background: Anterior ischemic optic neuropathy (AION) is characterized by infarction of the optic nerve head due to hypoperfusion of the posterior ciliary arteries and causes sudden blindness in adults on chronic dialysis, but has rarely been described in children. Unlike adults, children do not have comorbidities related to aging. ♦ Methods: We retrospectively analyzed data of 7 children on nocturnal continuous cycling peritoneal dialysis (CCPD) who developed AION identified within the Italian Registry of Pediatric Chronic Dialysis. We also summarized data from 10 cases reported in the literature. ♦ Results: Our 7 patients suffered from acute onset bilateral blindness. Their mean age was 3.2 years and chronic hypotension had been observed prior the AION in 3 of the 7 children. Low systolic blood pressure (SBP) was associated with higher risk of developing AION according to statistical analysis. None recovered completely. In total, 11 out of 16 experienced a partial recovery and no clear evidence emerged favoring specific treatments. ♦ Conclusions: Hypotensive children treated with CCPD are at increased risk of developing AION, which often results in irreversible blindness.

    Manufacturers of parenteral solutions adhere to European and US Pharmacopoeia standards to define safety and sterility. In response to excess cases of aseptic peritonitis in peritoneal dialysis patients using icodextrin-containing dialysate that met all pharmacopoeia standards, a global recall was issued in May, 2002. We aimed to establish the cause of aseptic peritonitis. We analysed 186 reports of aseptic peritonitis between September, 2001, and January, 2003. Extensive physical, chemical, and microbiological investigations of recalled dialysate were done. We calculated dose-response curves for peptidoglycan-induced interleukin 6 elaboration in peripheral blood mononuclear cells (PBMCs) from healthy donors and for sterile peritonitis in rats. Although its chemical constituents and concentrations of endotoxin were within pharmacopoeia specifications, the dialysis solution elicited an interlukin 6 response in vivo and in vitro. We identified peptidoglycan from thermophilic acidophilic bacteria (Alicyclobacillus acidocaldarius) as the contaminating proinflammatory substance. In the PBMC assay, strong dose-response relations were noted between peptidoglycan concentrations and interleukin 6. In rats injected with peptidoglycan, dose-dependent increases of intraperitoneal neutrophils and pyrogenic cytokines were recorded. We measured a positive relation between peptidoglycan concentrations in recalled dialysate and reports of aseptic peritonitis. After implementation of corrective actions, the rate of peritonitis returned to baseline. Excess cases of aseptic peritonitis in peritoneal dialysis patients were due to peptidoglycan contamination of dialysate by Alicyclobacillus. This outbreak serves as an example of how contemporary parenteral products with microbial contaminants can be considered safe under current pharmacopoeia tests, but provoke adverse clinical effects.

    A female patient with polycystic kidney disease (PKD) was treated with automated peritoneal dialysis when she reached end-stage renal disease. The patient has been doing very well on automated peritoneal dialysis (APD) for almost 6 years without peritonitis or abdominal hernias. Intra-abdominal pressures are lower in the supine position than in an erect or sitting position. Larger volumes of dialysate are better tolerated while the patient is supine, as during nocturnal APD. Therefore, APD is an option of the renal replacement therapy for patients with PKD.

    A 14-year-old girl, with end-stage renal disease on continuous ambulatory peritoneal dialysis (CAPD) the last 4 years, after an episode of Candida albicans was switched to hemodialysis. One month later she came back because of a palpable-painful abdominal mass and abdominal distention. Computed tomography (CT) and ultrasound examination demonstrated a demarkated fluid collection in the lower abdomen and pelvis. The cyst was drained percutaneously and the culture disclosed candida albicans which was treated with fluconasole. Two months later, the girl was admitted again with the same symptoms. An investigative laparotomy was undergone and the cyst was drained again. Fluid cultures were negative. CT abdomen examination six months later was negative for cyst relapse. In conclusion, intraperitoneal pseudocyst is a serious complication of CAPD. Surgical intervention may be preferable to percutaneous drainage.

    Dialysis fluid containing icodextrin is used in patients on peritoneal dialysis (PD) because of its significant ultrafiltration properties. The use of the fluid in treating patients with congestive heart failure resistant to diuretics has also been reported. The aim of the study was to evaluate water peritoneal transport during a 16-hour dialysis exchange performed using icodextrin-containing dialysis fluid. Eleven clinically stable patients were enrolled in the study (5 women and 6 men; mean age, 50.4 +/- 18.3 years), treated with PD for 26.9 +/- 22.4 months. Water transperitoneal transport was evaluated using a modified version of Babb-Randerson-Farrell thermodynamic model of membrane transport with human albumin marked with iodine as the marker of intraperitoneal volume. Based on blood and dialysate samples collected during the 16-hour dialysis exchange, the intraperitoneal volume of dialysate and dialysate reverse absorption were calculated. There were no clinical complications associated with the use of icodextrin fluid during the study. A significant increase in intraperitoneal volume of dialysate (950 ml on average) compared to the initial value was observed in the whole group at the 16th hour of the exchange. The study demonstrated that dialysis fluid with icodextrin ensured effective ultrafiltration during a 16-hour dialysis exchange. This indicates its potential usefulness in the treatment of patients with severe congestive heart failure with or without coexisting end-stage renal disease.

    Skin autofluorescence (SAF) measurement is a simple, noninvasive method to assess tissue advanced glycation end products (AGE). In patients with end-stage renal disease and in those on hemodialysis AGE production is increased. Less is known about those treated with peritoneal dialysis (PD). In this study we tested if SAF is influenced by clinical and treatment characteristics in PD patients.This cross-sectional study included 198 PD patients (of those, 128 were on traditional glucose-based solutions and 70 patients were partially switched to icodextrin-based PD). SAF measurements were done with a specific AGE Reader device. The impact of patients' age, gender, current diabetes, duration of PD, cumulative glucose exposure, body mass index, smoking habits and use of icodextrin on SAF values were tested with multiple regression analysis.Our analysis revealed that patients' age, current diabetes and icodextrin use significantly increase patients' SAF values (p = 0.015, 0.012, 0.005, respectively). AGE exposure of PD patients with diabetes and on icodextrin solution is increased. Further investigation is required whether this finding is due to the icodextrin itself or for a still unspecified clinical characteristic of PD population treated with icodextrin.

    Heat sterilization of peritoneal dialysis (PD) fluids leads to partial degradation of the osmotic agent to form reactive carbonyl structures, which significantly reduce the biocompatibility of PD fluids and impair long-term PD therapy. Hence, it is important to know the exact composition of the degradation products to improve biocompatibility of PD fluids. Our study conducted targeted screening for degradation products in polyglucose (icodextrin)-containing PD fluids (pGDPs) by applying o-phenylenediamine (OPD) to form stable derivatives, which were analyzed by ultrahigh-performance liquid chromatography with hyphenated diode array tandem mass spectrometry (UHPLC-DAD-MS/MS). For the first time, specific degradation products of polyglucose, namely, 4-deoxyglucosone (4-DG) and 3,4-dideoxypentosone (3,4-DDPS), could be identified in PD fluids. Further, a reaction product of 5-hydroxymethylfurfural (5-HMF) and OPD could be characterized to be (5-(1H-benzo[d]imidazol-2-yl)furan-2-yl)methanol. Additionally, 3-deoxyglucosone (3-DG) and 3-deoxygalactosone (3-DGal), both known to be present in glucose-based PD fluids, were also detected in polyglucose-containing fluids. Trapping a hitherto unknown degradation product with OPD yielded 1,4-bis(1H-benzo[d]imidazol-2-yl)-3,4-dihydroxybutan-1-one, which was present in heat- as well as filter-sterilized PD fluids.

    Cardiovascular disease is one of the leading causes of death in patients with advanced renal disease. The objective of this study was to investigate impairments in heart rhythm complexity in patients with end-stage renal disease. We prospectively analyzed 65 patients undergoing peritoneal dialysis (PD) without prior cardiovascular disease and 72 individuals with normal renal function as the control group. Heart rhythm analysis including complexity analysis by including detrended fractal analysis (DFA) and multiscale entropy (MSE) were performed. In linear analysis, the PD patients had a significantly lower standard deviation of normal RR intervals (SDRR) and percentage of absolute differences in normal RR intervals greater than 20 ms (pNN20). Of the nonlinear analysis indicators, scale 5, area under the MSE curve for scale 1 to 5 (area 1–5) and 6 to 20 (area 6–20) were significantly lower than those in the control group. In DFA anaylsis, both DFA α1 and DFA α2 were comparable in both groups. In receiver operating characteristic curve analysis, scale 5 had the greatest discriminatory power for two groups. In both net reclassification improvement model and integrated discrimination improvement models, MSE parameters significantly improved the discriminatory power of SDRR, pNN20, and pNN50. In conclusion, PD patients had worse cardiac complexity parameters. MSE parameters are useful to discriminate PD patients from patients with normal renal function.

    The ever increasing possibilities of prenatal diagnosis and intra-uterine treatment of malformations has created the need for simple and reproducible experimental models on which to build a better knowledge of the biology of the abnormal fetus. Using our own model of experimental gastroschisis (GX) in the chick embryo, we have undertaken to study whether transperitoneal exchanges of water and solutes take place after prolonged visceral exposure to the mixture of amniotic and allantoic fluids which has a greater content in Potassium, Urea, and Proteins and less sodium, chloride and glucose than fetal blood. After surgical evisceration of bowel on the 14th day, incubation was resumed until the 19th day and the embryos were then recovered for weighing and for blood sampling biochemical analysis. The chicks with GX had significantly increased serum Potassium and minimally increased Urea whereas Sodium and Chloride were moderately decreased. Our data confirm that a real peritoneal dialysis with transperitoneal exchange of water and solutes between extraembryonal fluids and the fetal internal environment does indeed take place in this model.

    A 73-year-old male on home peritoneal dialysis (PD) with recent diagnosis of atrial fibrillation presented with fatigue and dyspnea. Hyperthyroidism was diagnosed with TSH < 0.01 mIU/L and FT4 > 100 pmol/L. He had no personal or family history of thyroid disease. There had been no exposures to CT contrast, amiodarone, or iodine. Technetium thyroid scan showed diffusely decreased uptake. He was discharged with a presumptive diagnosis of thyroiditis. Three weeks later, he had deteriorated clinically. Possible iodine sources were again reviewed, and it was determined that povidone-iodine solution was used with each PD cycle. Methimazole 25 mg daily was initiated; however, he had difficulty tolerating the medication and continued to clinically deteriorate. He was readmitted to hospital where methimazole was restarted at 20 mg bid with high dose prednisone 25 mg and daily plasma exchange (PLEX) therapy. Biochemical improvement was observed with FT4 dropping to 48.5 pmol/L by day 10, but FT4 rebounded to 67.8 pmol/L after PLEX was discontinued. PLEX was restarted and thyroidectomy was performed. Pathology revealed nodular hyperplasia with no evidence of thyroiditis. Preoperative plasma iodine levels were greater than 5 times the upper limit of normal range. We hypothesize that the patient had underlying autonomous thyroid hormone production exacerbated by exogenous iodine exposure from a previously unreported PD-related source. PMID:28912982

    The objective of this article is to study the available works on comparison between icodextrin-based solutions (ICO) and glucose-based solutions (GLU) in peritoneal dialysis (PD) patients. The final aim was to get evidence for potential differences in metabolic management of PD patients by comparing the ICO with the GLU for the long dwell once a day. A meta-analysis of included reports, identified by MEDLINE and other sources, containing information on fasting plasma glucose, total cholesterol, triglycerides, and so on in PD patients, was performed. Nine randomized controlled trials (RCTs) (553 patients) were included. The ICO did not differ from the GLU with respect to fasting plasma glucose (weighted mean difference (WMD) = -0.76; 95% confidence interval (CI) = -1.79 to 0.28; Z = 1.43; p = 0.15), triglycerides (WMD = -0.66; 95% CI = -1.40 to 0.09; Z = 1.73; p = 0.08), and body weight (WMD = -2.02; 95% CI = -5.06 to 1.03; Z = 1.30; p = 0.20). But peritoneal creatinine clearance (WMD = 0.49; 95% CI = 0.34-0.64; Z = 6.35; p < 0.00001), urea clearance (WMD = 0.40; 95% CI = 0.25-0.55; Z = 5.12; p < 0.00001), and plasma total cholesterol (WMD = -0.40; 95% CI = -0.70 to -0.10; Z = 2.64; p = 0.008) were higher for the ICO versus the GLU. The ICO had been shown to have significant advantages over the GLU in small solute clearance and plasma total cholesterol. Patients, no matter what kind of PD solution was used, had no significant difference of plasma triglycerides, fasting plasma glucose, and body weight.

    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. Creating backup fistulas at the time of PD treatment start to allow emergency access for HD has proved to be inefficient, but it may be considered in patients with progressive difficulty in achieving adequate depuration and/or peritoneal ultrafiltration. A big challenge is represented by patients switching from PD to HD for unexpected infectious complications. Those patients need to start HD with a central venous catheter (CVC), but an alternative approach might be using an early cannulation graft, provided that infection has been cleared by the circulation. An early cannulation graft might also be used to considerably shorten the time spent using a CVC. In patients who need a conversion from HD to PD, urgent-start PD is now an accepted and well-established approach.

    Technique failure is a major limitation of peritoneal dialysis. Our study aimed to identify center- and patient-level predictors of peritoneal dialysis technique failure. All patients on incident peritoneal dialysis in Australia from 2004 to 2014 were included in the study using data from the Australia and New Zealand Dialysis and Transplant Registry. Center- and patient-level characteristics associated with technique failure were evaluated using Cox shared frailty models. Death-censored technique failure and cause-specific technique failure were analyzed as secondary outcomes. The study included 9362 patients from 51 centers in Australia. The technique failure rate was 0.35 (95% confidence interval, 0.34 to 0.36) episodes per patient-year, with a sevenfold variation across centers that was mainly associated with center-level characteristics. Technique failure was significantly less likely in centers with larger proportions of patients treated with peritoneal dialysis (>29%; adjusted hazard ratio, 0.83; 95% confidence interval, 0.73 to 0.94) and more likely in smaller centers (<16 new patients per year; adjusted hazard ratio, 1.10; 95% confidence interval, 1.00 to 1.21) and centers with lower proportions of patients achieving target baseline serum phosphate levels (<40%; adjusted hazard ratio, 1.15; 95% confidence interval, 1.03 to 1.29). Similar results were observed for death-censored technique failure, except that center target phosphate achievement was not significantly associated. Technique failure due to infection, social reasons, mechanical causes, or death was variably associated with center size, proportion of patients on peritoneal dialysis, and/or target phosphate achievement, automated peritoneal dialysis exposure, icodextrin use, and antifungal use. The variation of hazards of technique failure across centers was reduced by 28% after adjusting for patient-specific factors and an additional 53% after adding center-specific factors.

    When choosing a dialysis option for ADPKD patients, peritoneal dialysis (PD) is often discouraged, due to its potential drawbacks: risk of abdominal hernias and dialysis fluid leaks, risk of peritonitis and insufficient dialysis adequacy. The present study was designed to compare the outcomes and dialysis efficacy in ADPKD patients treated with PD, in comparison with non-ADPKD subjects. This study was a retrospective analysis of the data from the national PD registry in which 106 ADPKD and 1606 non-ADPKD incident PD patients were evaluated. Data on dialysis adequacy, risk of dialysis-associated complications, as well as patient and technique survival were compared between the groups. The ADPKD patients did not differ from the non-ADPKD controls in terms of dialysis adequacy. After a median observation time of 32 months, there were no differences in patient or technique survival. The risk of abdominal hernias and dialysis fluid leaks was twice as high in ADPKD subjects, compared to the non-ADPKD group. However, these complications did not result in a need for a permanent transfer to hemodialysis. Dialysis adequacy, and patient and technique survival are similar in the ADPKD and non-ADPKD patients treated with PD. PD seems a feasible treatment option for end-stage renal failure in the course of ADPKD.

    There is an ongoing increase in the number of elderly or frail patients requiring renal replacement therapy. Assisted automated peritoneal dialysis (aAPD) is one treatment option for this patient group and is becoming increasingly recognized as a distinct dialysis modality. In this article, we review the current status of aAPD and its evolution across Europe, describing the differences in service provision. We also report our experience locally of outcomes on our aAPD population over the last 4 years. We found that aAPD is a viable dialysis modality in the frail and elderly with limited lifespan, and complications of peritoneal dialysis are perhaps lower than would be expected in this population. This form of therapy also avoids the disruption to life which results from hospital-based dialysis. PMID:25949510

    Peritonitis remains a major complication of peritoneal dialysis (PD). A high peritonitis rate (HPR) affects continuous ambulatory peritoneal dialysis (CAPD) patients' technique survival and mortality. Predictors and outcomes of HPR, rather than the first peritonitis episode, were rarely studied in the Chinese population. In this study, we examined the risk factors associated with HPR and its effects on clinical outcomes in CAPD patients.This is a single center, retrospective, observational cohort study. A total of 294 patients who developing at least 1 episode of peritonitis were followed up from March 1st, 2002, to July 31, 2014, in our PD center. Multivariate logistic regression was used to determine the factors associated with HPR, and the Cox proportional hazard model was conducted to assess the effects of HPR on clinical outcomes.During the study period of 2917.5 patient-years, 489 episodes of peritonitis were recorded, and the total peritonitis rate was 0.168 episodes per patient-year. The multivariate analysis showed that factors associated with HPR include a quick occurrence of peritonitis after CAPD initiation (shorter than 12 months), and a low serum albumin level at the start of CAPD. In the Cox proportional hazard model, HPR was a significant predictor of technique failure. There were no differences between HPR and low peritonitis rate (LPR) group for all-cause mortality. However, when the peritonitis rate was considered as a continuous variable, a positive correlation was observed between the peritonitis rate and mortality.We found the quick peritonitis occurrence after CAPD and the low serum albumin level before CAPD were strongly associated with an HPR. Also, our results verified that HPR was positively correlated with technique failure. More importantly, the increase in the peritonitis rate suggested a higher risk of all-cause mortality.These results may help to identify and target patients who are at higher risk of HPR at the start of CAPD and to

    Background We searched for indicators to predict the prognosis of infectious peritonitis by measuring levels of complement proteins and activation products in peritoneal dialysis (PD) fluid (PDF) of patients at early stages of peritonitis. We retrospectively analyzed the relationship between the levels of sC5b-9, C3 and C4 in PDF and the subsequent clinical prognosis. Methods We measured levels of sC5b-9, C3 and C4 in PDF on days 1, 2 and 5 post-onset of peritonitis in 104 episodes of infectious peritonitis in PD patients from 2008 and retrospectively compared levels with clinical outcomes. Further analysis for the presence of causative microorganisms or to demonstrate bacterial culture negative peritonitis was performed and correlated with change of levels of sC5b-9 in PDF. Results When PD patients with peritonitis were divided into groups that either failed to recover from peritonitis and were finally withdrawn from PD (group 1; n = 25) or recovered (group 2; n = 79), levels of sC5b-9, C3 and C4 in PDF were significantly higher in group 1 patients compared to those in group 2 on day5. Analysis of microorganisms showed significantly higher sC5b-9 levels in PDF of peritonitis cases caused by culture negative peritonitis in group 1 compared with group 2 when we analyzed for individual microorganisms. Of note, on day5, the sC5b-9 levels in PDF were similarly high in peritonitis caused by fungi or other organisms. Conclusion Our results suggested that levels of complement markers in PDF, especially sC5b-9, have potential as surrogate markers to predict prognosis of PD-related peritonitis. PMID:28046064

    The authors present a series of 30 cases of acute supra- and inframesocolic peritonitis which, in addition to the treatment of their organic causes, benefitted from medical treatment by noxythioline, used as a peritoneal lavage, an irrigation with aspiration, or an instillation. A marked amelioration in the postoperative course was noted, particularly in those cases with infra-mesocolic peritonitis, with the absence of adhesions and suppurative collections on reintervention, and a rapid return to negativity of the positive bacteriological investigations performed systematically on the pe ritoneal fluid and on the drainage.

    Serum leptin levels of chronic kidney disease patients have been detected higher than normal population. The aim of this study was to investigate the effects of serum leptin levels on thrombocyte aggregation in peritoneal dialysis patients. Fourty three peritoneal dialysis patients were included in the study. Thrombocyte aggregation was calculated from the whole blood subsequently the effects of different concentrations of human recombinant leptin on thrombocyte aggregations were investigated. Four test cells were used for this process. While leptin was not added into the first test cell, increasing amounts of leptin was added into the second, third and fourth test cells to attain the concentrations of 25, 50 and 100 ng/ml respectively. Thrombocyte aggregation was inhibited by recombinant leptin in peritoneal dialysis patients. Thrombocyte aggregation mean values were found statistically significantly higher in first test cell when compared to leptin groups in peritoneal dialysis patients. For leptin groups we could not find any statistically significant differences for thrombocyte aggregation mean values between any of the groups. Further studies with larger number of peritoneal dialysis patients are required to prove the action of leptin on thrombocyte aggregation.

    Intraperitoneal administration of antibiotics is recommended for the treatment of peritoneal dialysis-related peritonitis. However, little data are available on a possible interference between peritoneal dialysis fluids and the activity of antimicrobial agents. Thus, the present in vitro study set out to investigate the influence of different peritoneal dialysis fluids on the antimicrobial activity of ampicillin, linezolid, and daptomycin against Enterococcus faecalis. Time-kill curves in four different peritoneal dialysis fluids were performed over 24 h with four different concentrations (1 × MIC, 4 × MIC, 8 × MIC, 30 × MIC) of each antibiotic evaluated. Cation-adjusted Mueller-Hinton broth was used as the comparator solution. All four peritoneal dialysis fluids evaluated had a bacteriostatic effect on the growth of Enterococcus faecalis. Compared to the cation-adjusted Mueller-Hinton broth comparator solution, the antimicrobial activity of all antibiotics tested was reduced. For ampicillin and linezolid, no activity was found in any peritoneal dialysis fluid, regardless of the concentration. Daptomycin demonstrated dose-dependent activity in all peritoneal dialysis fluids. Bactericidal activity was observed at the highest concentrations evaluated in Dianeal® PDG4 and Extraneal®, but not in concentrations lower than 30 × MIC and not in Nutrineal® PD4 and Physioneal® 40. The antimicrobial activity of ampicillin and linezolid is limited in peritoneal dialysis fluids in vitro. Daptomycin is highly effective in peritoneal dialysis fluids and might, thus, serve as an important treatment option in peritoneal dialysis-related peritonitis. Further studies are needed to evaluate the clinical impact of the present findings.

    ♦ Background, Objectives, and Methods: The number of patients on chronic peritoneal dialysis (CPD) is increasing rapidly on a global scale. We analyzed the International Pediatric Peritoneal Dialysis Network (IPPN) registry, a global database active in 33 countries spanning a wide range in gross national income (GNI), to identify the impact of economic conditions on CPD practices and outcomes in children and adolescents. ♦ Results: We observed close associations of GNI with the fraction of very young patients on dialysis, the presence and number of comorbidities, the prevalence of patients with unexplained causes of end-stage kidney disease, and the rate of culture-negative peritonitis. The prevalence of automated PD increased with GNI, but was 46% even in the lowest GNI stratum. The GNI stratum also affected the use of biocompatible peritoneal dialysis fluids, enteral tube feeding, calcium-free phosphate binders, active vitamin D analogs, and erythropoiesis-stimulating agents (ESAs). Patient mortality was strongly affected by GNI (hazard ratio per $10 000: 3.3; 95% confidence interval: 2.0 to 5.5) independently of young patient age and the number of comorbidities present. Patients from low-income countries tended to die more often from infections unrelated to CPD (5 of 9 vs 15 of 61, p = 0.1). The GNI was also a strong independent predictor of standardized height (p < 0.0001), adding to the impact of congenital renal disease, anuria, age at PD start, and dialysis vintage. Patients from the lower economic strata (GNI < $18 000) had higher serum parathyroid hormone (PTH) and lower serum calcium, and achieved lower hemoglobin concentrations. No impact of GNI was observed with regard to CPD technique survival or peritonitis incidence. ♦ Conclusions: We conclude that CPD is practiced successfully, albeit with major regional variation related to economic differences, in children around the globe. The variations encompass the acceptance of very young patients and

    Despite the interest generated by the increasing number of studies that measure Quality of Life among patients and caregivers, few of these studies measure the caregivers burden in Peritoneal Dialysis (PD). The main target of this study was to create a burden measure questionnaire applicable amongst caregivers of PD patients. 1) Patients had to be in PD treatment for more than 3 months; 2) Patients had to receive help with the PD treatment from a caregiver. The study was divided into 3 phases: 1st) design and use of the initial questionnaire; 2nd) a test-retest on a modified scale; and 3rd) to provide the questionnaire-3 to two collaborative centres with similar PD programs. Four groups of caregivers were established: A1:23, A2:17, B:7 and C:16 caregivers. We applied 5 scales (5): 1--Patient Dependence on caregiver, from caregivers' view (D); 2--Complete caregiver burden (CB), including 12 items which measure the caregivers' subjective burden, 3--Reduced caregiver burden (RB), as the one before but with only 8 items, 4--Repercussions on the caregiver (R), which measures objective burden; 5--Specific PD tasks (ST), a scale that measures the effort the tasks implied in the PD treatment represent for the caregiver. We studied 63 caregivers (table I): mean age: 53.43 (SD = 12.3); Sex: Females: 86.4%, Males: 13.6%, corresponding to 63 patients: mean age: 59.79 (SD = 15.9); Sex: Males: 80.3%, Females: 19.7%. Valuable results for reliability, unidimensionality, and discrimination were obtained in the 1st and 2nd phases, except for burden scale which was compound of two factors; then one of those factors was suppressed. In the 3rd phase, ANOVA did not show any differences between centres (table II). Consequently, all caregivers could be analysed together. Reliability results for each one of the third phase scales (table III) were: D: Cronbach alpha = 0,886; CB: alpha = 0,894; RB: alpha = 0,857; R: alpha = 0,892; ST: alpha = 0,62.

    Mycobacterium fortuitum is a ubiquitous, rapidly growing nontuberculous mycobacterium (NTM). It is the most commonly reported NTM in peritoneal dialysis (PD) associated peritonitis. We report a case of a 52-year-old man on PD, who developed refractory polymicrobial peritonitis necessitating PD catheter removal and shift to hemodialysis. Thereafter, M. fortuitum was identified in the PD catheter culture and in successive cultures of initial peritoneal effluent and patient was treated with amikacin and ciprofloxacin for six months with a good and sustained clinical response. Months after completion of the course of antibiotics, the patient successfully returned to PD. To our knowledge, this is the first reported case of M. fortuitum peritonitis in the field of polymicrobial PD peritonitis. It demonstrates the diagnostic yield of pursuing further investigations in cases of refractory PD peritonitis. In a systematic review of the literature, only 20 reports of M. fortuitum PD peritonitis were identified. Similar to our case, a delay in microbiological diagnosis was frequently noted and the Tenckhoff catheter was commonly removed. However, the type and duration of antibiotic therapy varied widely making the optimal treatment unclear.

  12. Satisfaction and Improvements in Peritoneal Dialysis Outcomes Associated with Telehealth.

    End stage renal disease (ESRD) affects approximately 660,000 persons in the US each year, representing a significant financial burden to the health care system and affected individuals. Telehealth approaches to care offer an important means of reducing costs as well as increasing autonomy for patients. Understanding patient satisfaction with telehealth provides a key towards eventual scalability. Quarterly surveys were conducted to characterize satisfaction with remote biometric monitoring (RBM) for blood pressure, weight, glucose and peritoneal dialysis (PD)-specific educational online videos for ESRD patients using PD. Of 300 participants, 67% participated in the surveys and provided baseline and at least one follow-up assessment. The majority were 45 to 64 years of age (50.5%), Black (64.5%), married or living with significant other (52.0%), and had more than a high school degree (73.0%). RBM was associated with perceived autonomy and confidence in health care activities and decreased negative perceptions of PD care and ESRD. The majority of participants (80.1%) indicated that they were satisfied or completely satisfied with the system. Participants found that the interface increased confidence, reduced frustration, and related perceptions were significantly and positively altered (p<0.05) for each of the separate telehealth components. Educational videos were well utilized with nearly half of the participants (42.5%) reporting that they watched at least one of the videos, and the majority reporting that the videos seen had an overall positive impact on health. Supplementing PD with telehealth has the potential to have a positive impact on patient perceptions of PD care and consequently improve clinical outcomes.

    Little information exists regarding the efficacy, modifiers, and outcomes of anemia management in children with CKD or ESRD. We assessed practices, effectors, and outcomes of anemia management in 1394 pediatric patients undergoing peritoneal dialysis (PD) who were prospectively followed in 30 countries. We noted that 25% of patients had hemoglobin levels below target (<10 g/dl or <9.5 g/dl in children older or younger than 2 years, respectively), with significant regional variation; levels were highest in North America and Europe and lowest in Asia and Turkey. Low hemoglobin levels were associated with low urine output, low serum albumin, high parathyroid hormone, high ferritin, and the use of bioincompatible PD fluid. Erythropoiesis-stimulating agents (ESAs) were prescribed to 92% of patients, and neither the type of ESA nor the dosing interval appeared to affect efficacy. The weekly ESA dose inversely correlated with age when scaled to weight but did not correlate with age when normalized to body surface area. ESA sensitivity was positively associated with residual diuresis and serum albumin and inversely associated with serum parathyroid hormone and ferritin. The prevalence of hypertension and left ventricular hypertrophy increased with the degree of anemia. Patient survival was positively associated with achieved hemoglobin and serum albumin and was inversely associated with ESA dose. In conclusion, control of anemia in children receiving long-term PD varies by region. ESA requirements are independent of age when dose is scaled to body surface area, and ESA resistance is associated with inflammation, fluid retention, and hyperparathyroidism. Anemia and high ESA dose requirements independently predict mortality. PMID:23471197

    Background Body weight has been increasing in the general population and is an established risk factor for hypertension, diabetes, and all-cause and cardiovascular mortality. Patients undergoing peritoneal dialysis (PD) gain weight, mainly during the first months of treatment. The aim of this study was to assess the relationship between body composition and metabolic and inflammatory status in patients undergoing PD. Methods This was a prospective, non-interventional study of prevalent patients receiving PD. Body composition was studied every 3 months using bioelectrical impedance (BCM®). We performed linear regression for each patient, including all BCM® measurements, to calculate annual changes in body composition. Thirty-one patients in our PD unit met the inclusion criteria. Results Median follow-up was 26 (range 17–27) months. Mean increase in weight was 1.8 ± 2.8 kg/year. However, BCM® analysis revealed a mean increase in fat mass of 3.0 ± 3.2 kg/year with a loss of lean mass of 2.3 ± 4.1 kg/year during follow-up. The increase in fat mass was associated with the conicity index, suggesting that increases in fat mass are based mainly on abdominal adipose tissue. Changes in fat mass were directly associated with inflammation parameters such as C-reactive protein (r = 0.382, P = 0.045) and inversely associated with high-density lipoprotein cholesterol (r=−0.50, P = 0.008). Conclusions Follow-up of weight and body mass index can underestimate the fat mass increase and miss lean mass loss. The increase in fat mass is associated with proinflammatory state and alteration in lipid profile. PMID:27274820

    The negative impact of environmental exposure of cadmium has been well established in the general population. However, the effect of cadmium exposure in chronic peritoneal dialysis (PD) patients remains uncertain.A total of 306 chronic PD patients were included in this 36-month observational study. Patients were stratified into 3 groups by the tertile of baseline blood cadmium levels (BCLs): high (>0.244 μg/L, n = 101), middle (0.130-0.244 μg/L, n = 102), and low (<0.130 μg/L, n = 103) for cross-sectional analyses. Mortality rates and cause of death were recorded for longitudinal analyses.Patients in the high-BCL group were older, more likely to have diabetes mellitus, had lower levels of serum albumin and lower percentage of lean body mass than patients in the low-BCL group. A multivariate logistic regression analysis revealed that logarithmic transformed BCL was independently associated with a higher risk of low turnover bone disease (odds ratio = 3.8, P = 0.005). At the end of the 36-month follow-up, 66 (21.6%) patients died. Mortality rates increased with higher BCLs (P for trend = 0.005). A Cox multivariate analysis showed that, using the low-BCL group as the reference, the high-BCL group had increased hazard ratios (HR) for all-cause mortality in chronic PD patients after adjusting for related variables (HR = 2.469, 95% confidence interval = 1.078-5.650, P = 0.043).In conclusion, BCL showed significant association with malnutrition and low turnover bone disease in chronic PD patients. Furthermore, BCL is an important determinant of mortality. Our findings suggest that avoiding environmental exposure to cadmium as much as possible is warranted in chronic PD patients.

    Up to a 10-fold difference in clinical outcomes between Australian peritoneal dialysis (PD) units exists. There is an international focus on the harmonisation of educational practices in PD to determine whether this may lead to improved patient outcomes. Evaluate the current teaching practices of nurses and patients in Australian PD units. An online survey with questions on nurse and patient training was made available to PD units in Australia. Thirty-eight (70%) of 54 PD units in Australia completed the survey. A written standardised curricula was utilised in 21 units (55%) for nursing staff and 30 units (86%) for patients, with 22% and 12% including an electronic delivery component for each group respectively. Universal teaching of adult learning principles was not demonstrated. The hours spent on teaching nursing staff ranged from <15 hours in 24% to >100 hours in 21% of units. The average number of hours spent by nurses each day to train patients ranged from <2 hours in 14% to >6 hours in 11% of units, with the average total training days ranging from 2-3 days in 14% to over 7 days in 14% of units. Staff and patient competency assessments were performed routinely in 37% and 74% of units respectively. Considerable differences exist amongst Australian PD units in the education of staff and patients. There is a general lack of delivery and competency assessment to meet educational standards. It remains to be seen if harmonisation of educational curricula can translate to improved clinical outcomes. This article is protected by copyright. All rights reserved.

    Icodextrin is a glucose polymer used as an alternative osmotic agent in peritoneal dialysis (PD) solutions. There are few data regarding the long-term stability of vancomycin in icodextrin PD solution. To determine the chemical stability of vancomycin in icodextrin PD solution in polyvinyl chloride containers over a 7 day period at 4, 24, and 37 degrees C. Study samples were prepared by adding 2000 mg vancomycin HCl to commercially available 2.0 L bags of icodextrin 7.5% PD solution. Nine bags were prepared and stored in the following conditions: 3 under refrigeration (5 degrees C), 3 at room temperature (24 degrees C), and 3 at body temperature (37 degrees C). Samples were withdrawn from each bag immediately after preparation and at predetermined intervals over the subsequent 7 days. Solutions were visually inspected for precipitation, cloudiness, or discoloration at each sampling interval. Total concentration of vancomycin in dialysate fluid was determined by high performance liquid chromatography. Under refrigeration, a mean +/- SD of 99.7% +/- 0.5% of the initial vancomycin concentration remained at 168 hours (7 days). At room temperature, 97.5% +/- 3.4% remained at 168 hours. At body temperature, 94.3% +/- 3.9% remained at 24 hours. Stability was not assessed beyond these time points. Premixed vancomycin-icodextrin PD solutions, whether stored refrigerated or at room temperature, were found to be stable for up to 7 days. However, we recommend that these solutions be kept refrigerated whenever possible. Solutions stored at body temperature were stable for up to 24 hours, permitting the practice of prewarming solutions prior to administration.

    Malnutrition remains one of the major predictors of mortality in peritoneal dialysis (PD) patients. The aim of the study was to evaluate the nutritional status of prevalent PD patients, and to determine the best predictors of outcome among anthropometric and laboratory indices of nutrition. The study included 106 prevalent PD patients from a single university-based unit. Anthropometric assessment at baseline included: body mass, body mass index (BMI), skinfold thickness, lean body mass (LBM), content of body fat (%F), mid-arm muscle circumference (MAMC). Laboratory analysis comprised of albumin and total cholesterol. Additionally, each patient underwent a subjective global assessment (SGA). The patients were followed for 36 months. Survival analyses were made with the Kaplan-Meier survival curve and the Cox proportional hazard model. Following SGA, malnutrition was diagnosed in 30 (28%) patients. Importantly, eight of the malnourished patients (27%) were nevertheless overweight or obese. Body weight and BMI showed complete lack of association with the outcome. In Kaplan-Meier analysis low: LBM, MAMC, albumin and cholesterol were significantly related to mortality. Cox analysis revealed that, following adjustment, LBM below median was independently associated with poor outcome (hazard ratio [HR] 3.15, 95% confidence interval [CI] 1.17-8.49, p=0.02). Moreover, the lowest quartile of total cholesterol showed independent association with mortality (HR 8.68, CI 2.14-35.21, p<0.01). Malnutrition is prevalent in patients undergoing PD, and overweight/obesity does not preclude its appearance. The most valuable nutritional indices in predicting outcome in this cohort were LBM and total cholesterol concentration.

    ♦ Introduction: Peritoneal dialysis (PD) patients are commonly required to transfer to hemodialysis (HD), however the literature describing the outcomes of such transfers is limited. The aim of our study was to describe the predictors of these transfers and their outcomes according to vascular access at the time of transfer. ♦ Methods: A retrospective cohort study using registry data of all adult patients commencing PD as their initial renal replacement therapy in Australia or New Zealand between 2004 – 2010 was performed. Follow-up was until 31 December 2010. Logistic regression models were constructed to determine possible predictors of transfer within both 6 and 12 months of PD commencement. Cox analysis and competing risks regression were used to determine the predictors of survival and transplantation post-transfer. ♦ Results: The analysis included 4,781 incident PD patients, of whom 1,699 transferred to HD during the study period. Logistic models did not identify any clinically useful predictors of transfer within 6 or 12 months (c-statistics 0.54 and 0.55 respectively). 67% of patients commenced HD with a central venous catheter (CVC). CVC use at transfer was associated with increased mortality (hazard ratio 1.37, 95% confidence interval (CI) 1.11 – 1.68, p = 0.003) and a borderline significant reduction in the incidence of transplantation (subhazard ratio 0.76, 95% CI 0.58 – 1.00, p = 0.05). ♦ Conclusions: It is difficult to predict the transfer to HD for incident PD patients. PD patients who commence HD with a CVC have a higher risk of mortality and a lower likelihood of undergoing renal transplantation. PMID:24497591

    Obesity is a chronic disease that is increasingly prevalent around the world and is a well-recognized risk factor for type 2 diabetes and hypertension, leading causes of end-stage renal disease (ESRD). The obese diabetic patient with ESRD is a challenge for the nephrologist with regard to the type of renal replacement therapy that should be suggested and offered to the patient. There is no evidence that either peritoneal dialysis or hemodialysis is contraindicated in obese ESRD patients. In the literature, we can find a discrepancy in the impact of obesity on mortality among hemodialysis vs. peritoneal dialysis patients. Several studies in hemodialysis patients suggest that a higher BMI confers a survival advantage - the so-called "reverse epidemiology". In contrast, the literature among obese peritoneal dialysis patients is inconsistent, with various studies reporting an increased risk of death, no difference, or a decreased risk of death. Many of these studies only spanned across a few years, and this is probably too short of a time frame for a realistic assessment of obesity's impact on mortality in ESRD patients. The decision for dialysis modality in an obese diabetic patient with ESRD should be individualized. According to the results of published studies, we cannot suggest PD or HD as a better solution for all obese diabetic patients. The obese patient should be educated about all their dialysis options, including home dialysis therapies. In this review, the available literature related to the dialysis modality in obese patients with diabetes and ESRD was reviewed.

    Thirty eight patients aged over 60 with end stage renal disease were treated by continuous ambulatory peritoneal dialysis for up to three years. Most of these patients, because of their age or coexisting diseases, had been considered to be unsuitable for haemodialysis by the criteria used before the advent of continuous ambulatory peritoneal dialysis in 1980. Actuarial patient survival at one and two years was 72% and 61% respectively, and only two patients were permanently transferred to haemodialysis. Twenty one of the 23 survivors were fully rehabilitated, the remaining two being partially disabled but living at home. Continuous ambulatory peritoneal dialysis permits more liberal selection of patients with end stage renal disease for renal replacement treatment with excellent survival and rehabilitation and without overburdening scarce hospital haemodialysis facilities.
