Abstract
OBJECT This study aims to conduct a systematic review and network meta-analysis to comprehensively evaluate the efficacy of various dressings in preventing exit-site infection (ESI) and peritonitis. METHODS We searched PubMed, Embase, Web of Science, CINAHL Plus with Full Text (EBSCO), Sino Med, Wan Fang Data, China National Knowledge Infrastructure (CNKI) from 1 January 1999 to 10 July 2023. The language restrictions were Chinese and English. Randomized controlled trials, non-randomized controlled trials, and self-controlled trials were included in this study. We used ROB 2 tool to evaluate the quality of the included literature. Two authors independently extracted the data according to the Cochrane Handbook. A Frequentist network meta-analysis was performed using Stata17.0 according to PRISAMA with a random effects model. RESULTS From 2092 potentially eligible studies, thirteen studies were selected for analysis, including nine randomized controlled studies, three quasi-experimental studies and one self-controlled trial. A total of 1229 patients were included to compare five types of exit site care dressings, named disinfection dressings, antibacterial dressings, non-antibacterial occlusive dressings, sterile gauze, and no-particular dressings. The outcome of prevention ESI is antibacterial dressings (SUCRA = 97.6) >non-antibacterial occlusive dressings (SUCRA = 68.3) >disinfection dressings (SUCRA = 50.6) >no-particular dressings (SUCRA = 23.9) >sterile gauze (SUCRA = 9.5). The antibacterial dressings were more effective than sterile gauze (OR = 0.13, 95%CI 0.04∼0.44), and no-particular dressing (OR = 0.18, 95%CI 0.07∼0.50) in preventing ESI; the non-antibacterial occlusive dressings were effective than sterile gauze (OR:0.30, 95%CI 0.16∼0.57). There is no statistical significance between no-particular dressings and other types of dressings in preventing the mature ESI. There is no statistical significance in the effectiveness of five types of dressings in preventing peritonitis. CONCLUSIONS The no-particular dressings maybe more cost-effective for preventing mature ESI. None of the dressings was more effective than another in preventing peritonitis. Then, none of the different types of dressing is strongly recommended for preventing ESI or peritonitis. RegistrationCRD42022366756.

Abstract
Importance More than 3.5 million people worldwide and 540 000 individuals in the US receive maintenance hemodialysis or peritoneal dialysis for the treatment of chronic kidney failure. The 5-year survival rate is approximately 40% after initiation of maintenance dialysis. Observations Hemodialysis and peritoneal dialysis remove metabolic waste and excess body water and rebalance electrolytes to sustain life. There is no recommended estimated glomerular filtration rate (eGFR) threshold for initiating dialysis, and patient-clinician shared decision-making should help determine when to initiate dialysis. Persistent signs and symptoms of uremia (eg, nausea, fatigue) and volume overload (eg, dyspnea, peripheral edema), worsening eGFR, metabolic acidosis, and hyperkalemia inform the timing of therapy initiation. A randomized clinical trial reported no mortality benefit to starting dialysis at higher eGFR (10-14 mL/min/1.73 m2) vs lower eGFR (5-7 mL/min/1.73 m2) levels. Observational data suggested no differences in 5-year mortality with use of hemodialysis vs peritoneal dialysis. Cardiovascular (eg, arrhythmias, cardiac arrest) and infection-related complications of maintenance dialysis are common. In the US, hemodialysis catheter-related bloodstream infections occur at a rate of 1.1 to 5.5 episodes per 1000 catheter-days and affect approximately 50% of patients within 6 months of catheter placement. Peritonitis occurs at a rate of 0.26 episodes per patient-year and affects about 30% of individuals in the first year of peritoneal dialysis therapy. Chronic kidney failure-related systemic complications, such as anemia, hyperphosphatemia, hypocalcemia, and hypertension, often require pharmacologic treatment. Hypotension during dialysis, refractory symptoms (eg, muscle cramps, itching), and malfunction of dialysis access can interfere with delivery of dialysis. Conclusions and Relevance In 2021, more than 540 000 patients in the US received maintenance hemodialysis or peritoneal dialysis for treatment of chronic kidney failure. Five-year survival rate after initiation of maintenance dialysis is approximately 40%, and the mortality rate is similar with hemodialysis and peritoneal dialysis. Decisions about dialysis initiation timing and modality are influenced by patient symptoms, laboratory trajectories, patient preferences, and therapy cost and availability and should include shared decision-making.

Abstract
BACKGROUND The preferred techniques for peritoneal dialysis catheterization are uncertain. Catheter implantation with formation of an inferiorly-directed tunnel and exit site is widely recommended to reduce the risk of infective complications. We aimed to compare percutaneous peritoneal dialysis catheter insertion using an upwardly-directed tract to catheter insertion using a downwardly-directed tract. METHODS A retrospective cohort study was performed on consecutive peritoneal dialysis catheterizations over a 10-year period at a single centre. Participants were classified into two groups: catheter insertion with an upward tunnel and exit site versus insertion with a downward tunnel and exit site. The primary outcome was peritoneal dialysis catheter survival. RESULTS There were 247 peritoneal dialysis catheters inserted during the study period. The median catheter survival was 18 months, with no difference between the two groups (p = 0.23). The 12-month catheter patency rates were 76% for catheters with an upward tract and 79% for catheters with a downward tract (p = 0.15). Multivariate analysis identified no clinical factors predictive of catheter survival. A downward catheter tunnel and exit site was associated with an increased incidence of peritonitis (0.23 vs 0.11 episodes per year; p ⩽ 0.01). CONCLUSION In this study, percutaneous peritoneal dialysis catheter insertion with an upward tunnel and exit site demonstrated similar catheter survival to insertion with a downward tunnel and exit site and was not associated with increased infections.

Abstract
Infection-related complications remain the most significant cause for morbidity and technique failure in infants, children and adolescents who receive maintenance peritoneal dialysis (PD). The 2024 update of the Clinical Practice Guideline for the Prevention and Management of Peritoneal Dialysis Associated Infection in Children builds upon previous such guidelines published in 2000 and 2012 and provides comprehensive treatment guidance as recommended by an international group of pediatric PD experts based upon a review of published literature and pediatric PD registry data. The workgroup prioritized updating key clinical issues contained in the 2012 guidelines, in addition to addressing additional questions developed using the PICO format. A variety of new guideline statements, highlighted by those pertaining to antibiotic therapy of peritonitis as a result of the evolution of antibiotic susceptibilities, antibiotic stewardship and clinical registry data, as well as new clinical benchmarks, are included. Recommendations for future research designed to fill important knowledge gaps are also provided.

Abstract
Introduction Internationally, peritoneal dialysis (PD) is increasingly being commenced within 2 weeks of catheter insertion. Studies are warranted to evaluate outcomes of this strategy. Methods This study examines outcomes of early-start PD (ESPD) and conventional-start PD (CSPD), commencing at ≤14 days and >14 days after catheter insertion, respectively. All adults with kidney failure within a large metropolitan PD unit initiating PD through a new catheter, inserted using laparoscopic or modified Seldinger technique, between August 2019 and August 2022, were included in this retrospective observational study. Demographic data and episodes of infectious and mechanical complications were collected using electronic medical records. Analysis was conducted using analysis of variance and Chi-square testing. A P-value < 0.05 was significant with Bonferroni correction performed where relevant. Kaplan-Meier and competing risks analyses were performed for time to PD-related peritonitis and transfer to hemodialysis. Results A total of 297 patients (70% male, mean age 58.7 years) were included, with 130 (43.8%) patients undertaking ESPD. Most patients had laparoscopically inserted catheters (65.3%) and 65 patients (22.0%) received prior hemodialysis. When compared to CSPD, ESPD was associated with a higher number of pericatheter leaks (6.9% vs. 0.6%, P = 0.003), with otherwise similar complication episodes and no significant difference with respect to time to PD-related peritonitis or transfer to hemodialysis. Catheter insertion technique or prior hemodialysis treatment did not significantly influence outcomes. Conclusion ESPD is associated with increased pericatheter leaks when compared to CSPD, with an otherwise similar complication profile.

Abstract
INTRODUCTION In South Africa, only children considered eligible for transplantation are offered dialysis as bridge to kidney transplantation. Maintenance peritoneal dialysis (PD) is preferred and has several advantages over hemodialysis (HD). While awaiting transplantation, PD may be discontinued due to permanent transfer to HD or death while on PD, of which the occurrence and burden is not known in our setting. We investigated the rate of discontinuation of maintenance PD, and associated factors among children awaiting a kidney transplant under challenging socio-economic circumstances in a low resource setting. METHODS Single center retrospective analysis of children receiving maintenance PD. Outcomes included the proportion of children who discontinued PD before transplantation, associated factors and timing of discontinuation, and the proportion transplanted. Time to discontinuation or transplantation was displayed using a Kaplan-Meier curve. RESULTS Sixty-seven children who received maintenance automated PD as initial dialysis modality were identified from the kidney transplant waiting list between January 2009 and December 2018. Complete data was available for 52 of the 67 children. Four children had prior failed kidney transplants. The median age was 11 years (interquartile range 6.0, 13.1). Overall, 17/52 (32.7%) children discontinued PD, with 13 (25%) transfers to HD and 4 deaths (7.7%), whereas 29/52 (55.8%) received a kidney transplant. Three of the deaths were PD related. Six children remained on maintenance PD at the end of the study period. Over a half of our patients discontinued PD by 12 months, and 80% by 30 months. Most PD discontinuations were associated with peritonitis. CONCLUSIONS The proportion discontinuing PD was high, highlighting the need to optimize measures to improve retention rates, especially through prevention of peritonitis.

Abstract
BACKGROUND Exit site infections are a risk factor for the development of peritonitis in patients on long-term peritoneal dialysis. Visual assessments of an exit site utilising currently available tools (Twardowski and Mid-European Pediatric Peritoneal Dialysis Study Group (MEPPS)) are necessary to objectively characterise the appearance of an exit site. The aim of this study was to assess the interobserver agreement of exit site evaluations utilising both exit site scoring tools. METHODS Exit site evaluations were independently performed by two evaluators during outpatient visits at 13 sites within the Standardizing Care to Improve Outcomes in Pediatric End Stage Kidney Disease collaborative. The frequency and percentage of evaluations where both reviewers agreed were calculated. A sub-analysis was performed looking at evaluations where disagreement occurred. RESULTS A total of 371 paired exit site evaluations were collected over 6 months. For the majority of evaluations (range: 78%-97% Twardowski, 78%-97% MEPPS), both reviewers agreed that no abnormality was present across all domains. When the analysis was restricted to evaluations where at least one reviewer noted an abnormality, interobserver agreement fell across all domains (range: 31%-61% Twardowski, 56%-66% MEPPS). Disagreements more commonly occurred regarding the presence versus absence of an abnormality, rather than a difference in the severity of an abnormality. CONCLUSIONS Whereas interobserver agreement is high when the appearance of a peritoneal dialysis catheter exit site is characterised as 'normal', interobserver disagreement is common when the appearance of the exit site is 'abnormal'. Further work is warranted to improve interobserver agreement of exit site assessments and to identify domains conferring an increased risk of infection.

Abstract
A nine-year-old male with trisomy 21, end-stage renal disease (ESRD) due to reflux nephropathy presented with suspected peritoneal dialysis (PD) catheter-associated peritonitis. One week after receiving an intraperitoneal antibiotic, he presented again with persistent peritonitis symptoms and bloody PD fluid. He underwent exploratory laparotomy, abdominal washout, and PD catheter removal. Mycobacterium abscessus (M. abscessus) was found in the intraoperative peritoneal fluid culture. After the catheter removal, the child's symptoms significantly improved without antimicrobial medications. He was maintained on hemodialysis three times a week and underwent a successful kidney transplant eight months after this episode. Non-tuberculous mycobacterial peritonitis should be considered in patients with culture-negative peritonitis when there is no intraperitoneal antibiotic response. M. abscessus is a rapidly growing atypical Mycobacterium found in the environment and can contaminate medical devices. Our case involved an infection from a contaminated PD catheter since the patient's symptoms improved after PD catheter removal.

Abstract
INTRODUCTION Peritoneal dialysis (PD) related infections are a significant obstacle leading to PD discontinuation. Since catheter related infections (CRI), defined as exit site infections and/or tunnel infection, can progress to peritonitis, vigorous efforts are implemented in CRI prevention. Following an increased CRI rate in our institution, partially related to environmental organisms found in water distribution systems, we hypothesized that exit site care that includes prevention of water exposure-related pathogens may reduce CRI. METHODS In this prospective single center study, we compared a contemporary cohort consisting of PD patients who implemented the modified exit-site care protocol, mainly including water avoidance during shower with stoma bag usage and local Mupirocin ointment against a historical control group before the protocol implementation. The historical cohort was allowed water exposure and used local gentamicin ointment. The primary outcome was the development of a CRI. Secondary outcomes were PD associated peritonitis and infection related outcomes. RESULTS There were 55 patients in contemporary cohort and 58 in historical group. The CRI rate was significantly lower in study group (0.11/episodes per patient year [EPP]) compared to control group (0.71 EPP), p < 0.001. A multivariate Cox regression analysis demonstrated a protective effect of being in the contemporary cohort compared to historical group (HR for first CRI = 12.0 95%CI: 4.0-35.7, p < 0.001). Peritonitis rate was significantly lower in contemporary cohort (0.19/EPP) compared to the historical group (0.40/EPP), p = 0.011. Transfer to hemodialysis was significantly lower in contemporary cohort than historical group (7.3% vs 31.0% in contemporary and historical group respectively, HR = 0.2, 95%CI; 0.05-0.6, p = 0.001). CONCLUSION An exit site care protocol that includes water avoidance and local Mupirocin use reduced substantially both CRI and peritonitis rate in patients treated with PD.

BMC Nephrol 2024; 25:273. [PMID: 39187762 PMCID: PMC11346171 DOI: 10.1186/s12882-024-03714-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2023] [Accepted: 08/16/2024] [Indexed: 08/28/2024] Open
Abstract
BACKGROUND Refractory exit-site infections (ESIs) and tunnel infections (TIs) are challenging complications for patients undergoing peritoneal dialysis (PD). This study compared the outcomes of surgical intervention, notably the cuff-shaving (CS) procedure coupled with negative-pressure wound therapy (NPWT), and conservative management strategies for patients with refractory ESI and TI. METHODS We retrospectively reviewed patients who underwent PD at our center, focusing on the incidence and management of ESI and TI. We evaluated and compared treatment outcomes, including ESI scores, frequency of ESI and/or TI, identification of causative microorganisms, and duration of catheter survival or time until removal. RESULTS We identified 97 episodes of catheter-related ESI and/or TI across 71 patients with an incidence rate of 0.15 episodes per patient-year. Of the 23 patients with refractory ESI and/or TI, surgical intervention was performed in 8, while 15 chose conservative management. In the one-month follow-up, patients who underwent CS combined with NPWT showed no complications such as leakage, and their local symptoms resolved completely. The mean PD catheter survival time was significantly longer in the surgical group (29.38 ± 7.25 months) than in the conservative group (7.86 ± 2.13 months). Surgical intervention demonstrated a significantly higher therapeutic efficacy and extended catheter survival. CONCLUSIONS The combination of CS and NPWT as a surgical approach is crucial for eradicating infectious foci and significantly improving the longevity of PD catheter function. This integrated surgical strategy offers a promising solution for the management of refractory ESI and TI in patients undergoing PD.

Abstract
BACKGROUND Peritoneal dialysis (PD) catheter related infections continue to be a major cause of morbidity and transfer to hemodialysis (HD) in PD patients. The treatment of tunnel infection (TI) could be challenging, especially when the infection involves the superficial cuff requiring the removal of the catheter. To spare the patient the loss of the catheter and the transfer to HD, several mini-invasive surgical techniques have been proposed as rescue therapy. Furthermore, nowadays, the rapid growth of digital technology has enormously increased the diagnostic sensibility of the echo signal allowing to accurately defines the extent of the infectious process along the PD catheter tunnel. METHODS Between 1st January 2020 and 31st December 2021 seven patients who underwent exit-site relocation by external splicing and cuff removal at our institution due to refractory TI were included in the study. All patients were followed until 12 months after the procedure. As soon as TI was defined refractory to the medical therapy, an ultrasonographic examination of the catheter tunnel was performed to define the extent of the infectious episode. RESULTS Among the 7 infectious episodes, 4 were caused by P. aeruginosa, and 3 by S. aureus. Around the superficial cuff the hypo/anechoic collections detected by ultrasounds showed a mean diameter of 3.05 ± 0.79 mm. The exit-site relocation by external splicing and cuff removal was successful in all cases (7/7, 100%). CONCLUSIONS In our experience the use of exit site relocation by external splicing and cuff removal as rescue therapy for TI with positive ultrasounds for TI limited to superficial cuff involvement and without secondary peritonitis, yielded to promising results with a success rate of 100%. This preliminary experience underlines the paramount usefulness of tunnel echography in accurately defining the extent of TI and, consequently, guiding the choice of the therapeutical approach in refractory TI.

Abstract
BACKGROUND Peritoneal dialysis (PD) is an important renal replacement therapy in patients with end-stage renal disease. PD catheters remain the lifeline for patients undergoing PD. The catheter technique survival rate is considered a core PD outcome domain. CASE SUMMARY The PD catheter spontaneously dislodged in a patient undergoing PD during regular fluid exchange without pain. Abdominal computed tomography showed a tunnel infection. A double-cuff straight Tenckhoff catheter had been inserted using the Seldinger technique. Before this incident, the patient had a history of tunnel infections. We speculate that recurrent tunnel infections and catheter insertion using the Seldinger technique may have led to catheter dislodgement. CONCLUSION The present case suggests that clinicians should more rigorously assess the persistence of catheter-related infections concerning the potential complications arising from catheter dislodgement associated with the Seldinger technique.

Abstract
A review from the last seven years (August 2016-July 2023) of questions posted to the International Society for Peritoneal Dialysis (ISPD) website "Questions about PD" by nurses and physicians from around the world revealed that 19 of the questions were associated with optimal approaches for preventing, assessing, and managing issues related to PD catheter non-infectious complications. Our review focused on responses to these questions whereby existing best practice recommendations were considered, if available, relevant literature was cited and differences in international practices discussed. We combined similar questions, revised both the original questions and responses for clarity, as well as updated the references to these questions. PD catheter non-infectious complications can often be prevented or, with early detection, the potential severity of the complication can be minimized. We suggest that the PD nurse is key to educating the patient on PD about PD catheter non-infectious complications, promptly recognize a specific complication and bring that complication to the attention of the Home Dialysis Team. The questions posted to the ISPD website highlight the need for more education and resources for PD nurses worldwide on the important topic of non-infectious complications related to PD catheters, thereby enabling us to prevent such complications as PD catheter malfunction, peri-catheter leakage and infusion or drain pain, as well as recognize and resolve these issues promptly when they do arise, thus allowing patients to extend their time on PD therapy and enhance their quality of life whilst on PD.

Abstract
This review outlines the epidemiology, characteristics, risk factors, and prognosis of peritoneal dialysis (PD)-related peritonitis, PD catheter-related infections, and the effects of assisted PD in elderly patients from the Japanese perspective. Based on the literature, the incidence of peritonitis is likely to be higher in elderly patients than in younger patients. The most frequent causative bacteria in elderly patients are Gram-positive bacteria, as in adult PD patients, most commonly due to transcatheter infection. However, elderly patients may have difficulty recognizing cloudy drainage fluid due to decreased visual acuity. Hypokalemia, the use of gastric acid suppressants, prophylactic antibiotic use before endoscopy, biocompatible fluids and hypoalbuminemia considered modifiable risk factors for peritonitis. However, the mechanism by which treatment of hypokalemia prevents peritonitis is unknown. Currently, the relationship between gastric acid suppression therapy and peritonitis in elderly patients is debatable, with no evidence to strongly recommend uniform discontinuation of gastric acid suppression therapy. Exit-site infection (ESI) is a major risk factor for the development of peritonitis, and appropriate prevention and management of ESI may reduce infection-related hospitalizations in PD patients. Currently, no randomized, controlled trials have verified the effectiveness of antibiotic application for ESI in Japan, but results from other countries are awaited. In assisted PD, it is extremely important that family members, caregivers, and nurses who support the procedure receive sufficient education and training from medical professionals familiar with PD. Early detection and treatment of PD-related infections are required because the risk of death increases in elderly patients.

Abstract
Background Wound dressing is intended to provide a physical barrier from microorganisms. Spray dressing is convenient and can be applied to wounds of various contours. In July 2020, a cluster of four Burkholderia cepacia complex (BCC) exit site infections was identified among peritoneal dialysis patients in a regional hospital in Hong Kong. In response, our hospital infection control team conducted an epidemiologic investigation. Methods We conducted a retrospective cohort study of peritoneal dialysis patients with culture-confirmed BCC exit site infections from January 2011 to July 2020. Outbreak investigations, including case finding, molecular typing and post-outbreak surveillance, were performed. Discussion A substantial increase in BCC exit site infections has been observed since 2013, rising from 0.23 in 2012 to 1.09 episodes per 100 patient-year in 2015, with the number of cases in the first half of 2020 already surpassing the total from 2019. The potential source had been traced to a spray dressing introduced to exit site care in December 2012. Burkholderia cepacia complex was isolated from both the unopened and in-use sprays from the same lot. Multilocus sequence typing analysis confirmed their genetic relatedness. The spray dressing was subsequently removed from exit site care. Post-outbreak surveillance over two years showed a marked and sustained decrease in BCC exit site infection. Conclusion Water-based spray dressing can be a source of BCC causing wound infections. The use of contaminated spray dressing, especially in chronic wounds with proximity to indwelling catheters, may pose an inherent risk to patients.

Abstract
BACKGROUND Peritoneal dialysis-related peritonitis (PDRP) is the most common complication of peritoneal dialysis (PD), which can lead to poor outcomes if not diagnosed and treated early. We aimed to investigate the diagnostic accuracy of MMP-8 and IL-6-based point-of-care tests (POCTs) in diagnosing PDRP in PD patients. METHODS This retrospective chart review study was conducted at a comprehensive kidney center in Qatar. It involved all adult PD patients who underwent PDRP from July 2018 to October 2019 and for whom MMP-8 and IL-6-based POCTs were used to diagnose presumptive peritonitis. Measures of diagnostic accuracy were computed. Peritoneal fluid effluent analysis was the reference standard. RESULTS We included 120 patients (68 [56.7%] females, ages 55.6 ± 15.6 years, treatment duration 39.5 ± 30.4 months [range: 5-142 months]). In this population, MMP-8 and IL-6-based POCTs yielded 100% in all dimensions of diagnostic accuracy (sensitivity, specificity, positive and negative predictive values). CONCLUSIONS MMP-8 and IL-6-based POCTs might be helpful in the early detection of PDRP. This monocentric observation requires further confirmation in a prospective multicentric setting.

Abstract
BACKGROUND Exit-site infection (ESI) is a common recurring complication in patients undergoing peritoneal dialysis (PD). Sucrose and povidone-iodine (SPI) mixtures, antimicrobial ointments that promote wound healing, have been used for the treatment of ulcers and burns, but their efficacy in exit-site care is still unclear. METHODS This single-center retrospective observational study included patients who underwent PD between May 2010 and June 2022 and presented with episodes of ESI. Patients were divided into SPI and non-SPI groups and followed up from initial ESI onset until PD cessation, death, transfer to another facility, or June 2023. RESULTS Among the 82 patients (mean age 62, [54-72] years), 23 were treated with SPI. The median follow-up duration was 39 months (range, 14-64), with an overall ESI incidence of 0.70 episodes per patient-year. Additionally, 43.1% of second and 25.6% of third ESI were caused by the same pathogen as the first. The log-rank test demonstrated significantly better second and third ESI-free survival in the SPI group than that in the non-SPI group (p < 0.01 and p < 0.01, respectively). In a Cox regression analysis, adjusting for potential confounders, SPI use was a significant predictor of decreased second and third ESI episodes (hazard ratio [HR], 0.22; 95% confidence interval [CI], 0.10-0.52 and HR, 0.22; 95%CI, 0.07-0.73, respectively). CONCLUSIONS Our results showed that the use of SPI may be a promising option for preventing the incidence of ESI in patients with PD. TRIAL REGISTRATION This study was approved by the Keio University School of Medicine Ethics Committee (approval number 20231078) on August 28, 2023. Retrospectively registered.

Abstract
Peritoneal dialysis (PD) represents an important treatment choice for patients with kidney failure. It allows them to dialyze outside the hospital setting, facilitating enhanced opportunities to participate in life-related activities, flexibility in schedules, time and cost savings from reduced travel to dialysis centers, and improved quality of life. Despite its numerous advantages, PD utilization has been static or diminishing in parts of the world. PD-related infection, such as peritonitis, exit-site infection, or tunnel infection, is a major concern for patients, caregivers, and health professionals-which may result in hesitation to consider this as treatment or to cease therapy when these complications take place. In this review, the definition, epidemiology, risk factors, prevention, and treatment of PD-related infection on the basis of the contemporary evidence will be described.

Uptake and Outcomes of Peritoneal Dialysis among Aboriginal and Torres Strait Islander People: Analysis of Registry Data. Kidney Int Rep 2024; 9:1484-1495. [PMID: 38707791 PMCID: PMC11068974 DOI: 10.1016/j.ekir.2024.01.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 01/24/2024] [Accepted: 01/29/2024] [Indexed: 05/07/2024] Open
Abstract
Introduction Peritoneal dialysis (PD) enables people to use kidney replacement therapy (KRT) outside of healthcare-dependent settings, a strong priority of Aboriginal and Torres Strait Islander people. Methods We undertook an observational study analyzing registry data to describe access to PD and its outcome as the first KRT among Aboriginal and Torres Strait Islander people between January 1, 2004 and December 31 2020. Results Out of 4604 Aboriginal and Torres Strait Islander people, reflecting 10.4% of all Australians commencing KRT, PD was the first KRT modality among 665 (14.4%). PD utilization was 17.2% in 2004 to 2009 and 12.7% in 2016 to 2020 (P = 0.002); 1105 episodes of peritonitis were observed in 413 individuals, median of 3 (interquartile range [IQR], 2-5) episodes/patient. The crude peritonitis rate was 0.53 (95% confidence interval [CI], 0.50-0.56) episodes/patient-years without any significant changes over time. The median time to first peritonitis was 1.1 years. A decrease in the peritonitis incidence rate ratio (IRR) was observed in 2016 to 2020 (IRR, 0.63 [95% CI, 0.52-0.77], P < 0.001) compared to earlier eras (2010-2015: IRR, 0.90 [95% CI, 0.76-1.07], P = 0.23; Ref: 2004-2009). The cure rates decreased from 80.0% (n = 435) in 2004 to 2009, to 70.8% (n = 131) in 2016 to 2020 (P < 0.001). Conclusion Aboriginal and Torres Strait Islander people who utilized PD as their first KRT during 2004 to 2020 recorded a higher peritonitis rate than the current benchmark of 0.4 episodes/patient-years. The cure rates have worsened recently, which should be a big concern. There is an exigent need to address these gaps in kidney care for Aboriginal and Torres Strait Islander people.

Abstract
Rationale & Objective Staphylococcus lugdunensis (S lugdunensis) is a coagulase-negative staphylococcus species that has been increasingly recognized to cause serious infections with virulence resembling Staphylococcus aureus (S aureus). No studies have evaluated the characteristics and outcomes of patients with S lugdunensis peritoneal dialysis-related peritonitis compared with those with S aureus peritonitis. We aim to evaluate the clinical course of peritonitis as caused by these organisms. Study Design A retrospective matched comparative analysis involving a single tertiary center from July 2000 to July 2020. Setting & Participants Forty-eight episodes of S aureus peritonitis were matched to 19 cases of S lugdunensis peritonitis. Analytical Approach The cases were individually matched for year of peritonitis, sex, age (±10 years), and Charlson Comorbidity Index (±3). A comparative analysis was performed between the 2 organisms. The outcome includes responses at day 5 of peritonitis and the rate of complete response. Results There is a higher predilection of diabetes in those with S aureus peritonitis than in those with S lugdunensis (64.6% vs 31.6%; P = 0.03). Patients with S aureus peritonitis also have a much higher total cell count at presentation (4,463.9 ± 5,479.5 vs 1,807.9 ± 3,322.7; P = 0.05); a higher prevalence of poor response at day 5 (50.0% vs 15.8%; P = 0.03); a lower rate of complete response (64.6% vs 94.7%; P = 0.01) and are more prone to relapse with the same organism (29.2% vs 0%, respectively; P = 0.01) as compared to those with S lugdunensis. Limitations The result of this small retrospective study involving a single center may not be generalizable to other centers. There is also no data for comparative analysis on other coagulase-negative staphylococci such as Staphylococcus epidermidis, which belongs to the same family as S lugdunensis. Conclusions Although S aureus peritonitis is more virulent with significant morbidity, S lugdunensis can cause similarly serious peritonitis. This largest case series of S lugdunensis peritonitis enabled better characterization of clinical features and outcomes of patients with S lugdunensis peritonitis.

Abstract
Effective treatment of infections is a growing challenge owing to antimicrobial resistance. Peritoneal dialysis (PD) patients experience more frequent hospitalisations than the general population and have greater exposure to antibiotics, making them particularly vulnerable to this threat. Over the last decade, we have noted a surge in cases of complicated peritoneal dialysis-associated peritonitis (PD peritonitis) caused by antimicrobial-resistant organisms, including extended-spectrum beta-lactamase (ESBL), AmpC beta-lactamase-producing Enterobacterales, Pseudomonas aeruginosa and fungi. Practitioners must be alert to these organisms, seek early recognition of these resistance patterns and make timely adjustments in order to avoid delay in treatment that may increase risk of PD catheter removal and technique failure. We present a case of successful treatment of ESBL peritonitis, highlight its challenges, while providing guidance on management of other unusual and complicated PD peritonitis.

Abstract
BACKGROUND To analyse the nature of medical or technical emergency issues of ambulatory peritoneal dialysis (PD) patients calling a nurse-provided emergency PD support service of a reference centre that is provided all year in the after-hours. METHODS We retrospectively analysed patients' chief complaint, urgency, resolution of and association to current PD treatment and modality directed to an on-call nurse-provided PD support service from 2015-2021 based on routinely collected health data. Calls were systematically categorized being technical/procedural-, medical-, material-related or type of correspondence. Call urgency was categorized to have "immediate consequence", inquiry was eligible for "processing next working day" or whether there was "no need for further action". Call outcomes were classified according to whether patients were able to initiate, resume or finalize their treatments or whether additional interventions were required. Unexpected adverse events such as patients' acute hospitalization or need for nurses' home visits were evaluated and quantified. RESULTS In total 753 calls were documented. Most calls were made around 7:30 a.m. (5:00-9:00; median, 25-75th CI) and 6:30 p.m. (5:00-8:15). 645 calls were assigned to continuous ambulatory- (CAPD) or automated PD (APD). Of those, 430 calls (66.7%) had an "immediate consequence". Of those 77% (N = 331) were technical/procedural-, 12.8% (N = 55) medical- and 6.3% (N = 27) material related issues. 4% (N = 17) were categorized as other correspondence. Issues disrupting the course of PD were identified in 413 cases. In 77.5% (N = 320) patients were able to initiate, resume or finalize their treatment after phone consultation. Last-bag exchange was used in 6.1% enabling continued therapy in 83.6%. In 35 cases a nurse visit at patients' home or patients' visit to the practice at the earliest possible date were required, while hospitalization was required in seven medical category cases (5.4% and 1.09% of total assessed calls, respectively). CONCLUSION The on-call PD-nurse provides patient support for acute and imminent issues enabling them to successfully initiate, resume or finalize their prescribed treatment. Nurses triage of acute conditions facilitated rapid diagnostics and therapy. Maintaining quality PD homecare, the provision of trained personnel is indispensable. The information gathered in this study may therefore be used as a foundation to tailor educational programs for nephrology nurses and doctors to further develop their competencies in PD.

Abstract
PURPOSE OF REVIEW Infections in hospitalized patients awaiting solid organ transplantation can pose complicated diagnostic and therapeutic challenges. Goals of management include stabilizing the patient, treating or controlling infections, and decreasing the risk of reactivation of infection after transplant. RECENT FINDINGS Groups such as The Organ Procurement and Transplantation Network, American Society of Transplantation Infectious Diseases Community of Practice and the European Society of Clinical Microbiology and Infectious Diseases have updated their guidelines on screening and treatment of infection in transplant candidates. There are also recent developments in therapeutic options for tuberculosis, COVID-19, Clostridioides difficile colitis, bloodstream infections, and other common infections. SUMMARY Ideally, antimicrobial therapy should be complete prior to transplantation. In situations in which completion of therapy prior to transplant is not feasible, therapy may need to be prolonged or modified. In most situations, infections can be managed similarly to the general population, although some infections, particularly fungal and mycobacterial, require a different management approach. We review disease- and organ-specific management.

Abstract
Home-based dialysis modalities offer both clinical and practical advantages to patients. The use of the home-based modalities, peritoneal dialysis and home hemodialysis, has been increasing over the past decade after a long period of decline. Given the increasing frequency of use of these types of dialysis, it is important for clinicians to be familiar with how these types of dialysis are performed and key clinical aspects of care related to their use in patients with end-stage kidney disease.

Abstract
INTRODUCTION Peritoneal dialysis (PD), as a home treatment, ensures better patient autonomy and lower intrusiveness compared to hemodialysis. However, choosing PD comes with an increased burden of responsibility that the patient may not always be able to bear, due to advanced age and deteriorating health condition. Various approaches have been explored to address this issue and mitigate its primary complications. In this study, we aim to present the ongoing PD training at-home program implemented by the Vicenza PD Center, and evaluate its impact on patients' prognoses. MATERIAL AND METHODS We enrolled 210 patients who underwent PD at Vicenza Hospital between 1 January 2019 and 1 January 2022 for a minimum of 90 days. Each patient was observed retrospectively for one year. We categorized the patients into three groups based on their level of autonomy regarding their PD management: completely independent patients; patients able to perform some parts of the PD method on their own, while the remaining aspects were carried out by a caregiver; and patients who required complete assistance from a caregiver, like in the assisted PD program (asPD). RESULTS A total of 70% of the PD population were autonomous regarding their PD therapy, 14% had an intermediate degree of autonomy, and 16% were entirely dependent on caregivers. The PD nurses performed a median of four home visits per patient per year, with a tendency to make more visits to patients with a lower degree of autonomy. All the groups achieved similar clinical outcomes. At the end of the year of observation, only 6% of the patients witnessed a decline in their autonomy level, whereas 7% demonstrated an enhancement in their level of autonomy, and 87% remained stable. CONCLUSIONS A home care assistance program ensures clinical support to a household with the purpose of improving the empowerment of the PD population and reducing the prevalence of assisted PD. Ongoing PD training at home helps patients to maintain a stable degree of autonomy and stay in their home setting, even though they present with relative attitudinal or social barriers.

Abstract
Since they are difficult and sometimes impossible to treat, infections sustained by multidrug-resistant (MDR) pathogens, emerging especially in nosocomial environments, are an increasing global public health concern, translating into high mortality and healthcare costs. In addition to having acquired intrinsic abilities to resist available antibiotic treatments, MDR bacteria can transmit genetic material encoding for resistance to non-mutated bacteria, thus strongly decreasing the number of available effective antibiotics. Moreover, several pathogens develop resistance by forming biofilms (BFs), a safe and antibiotic-resistant home for microorganisms. BFs are made of well-organized bacterial communities, encased and protected in a self-produced extracellular polymeric matrix, which impedes antibiotics' ability to reach bacteria, thus causing them to lose efficacy. By adhering to living or abiotic surfaces in healthcare settings, especially in intensive care units where immunocompromised older patients with several comorbidities are hospitalized BFs cause the onset of difficult-to-eradicate infections. In this context, recent studies have demonstrated that quaternary ammonium compounds (QACs), acting as membrane disruptors and initially with a low tendency to develop resistance, have demonstrated anti-BF potentialities. However, a paucity of innovation in this space has driven the emergence of QAC resistance. More recently, quaternary phosphonium salts (QPSs), including tri-phenyl alkyl phosphonium derivatives, achievable by easy one-step reactions and well known as intermediates of the Wittig reaction, have shown promising anti-BF effects in vitro. Here, after an overview of pathogen resistance, BFs, and QACs, we have reviewed the QPSs developed and assayed to this end, so far. Finally, the synthetic strategies used to prepare QPSs have also been provided and discussed to spur the synthesis of novel compounds of this class. We think that the extension of the knowledge about these materials by this review could be a successful approach to finding effective weapons for treating chronic infections and device-associated diseases sustained by BF-producing MDR bacteria.

Abstract
BACKGROUND This multi-institutional, observational study examined whether the outcomes after peritoneal dialysis (PD) catheter placement in Japan meet the audit criteria of the International Society for Peritoneal Dialysis (ISPD) guideline and identified factors affecting technique survival and perioperative complications. METHODS Adult patients who underwent first PD catheter placement for end-stage kidney disease between April 2019 and March 2021 were followed until PD withdrawal, kidney transplantation, transfer to other facilities, death, 1 year after PD start or March 2022, whichever came first. Primary outcomes were time to catheter patency failure and technique failure, and perioperative infectious complications within 30 days of catheter placement. Secondary outcomes were perioperative complications. Appropriate statistical analyses were performed to identify factors associated with the outcomes of interest. RESULTS Of the total 409 patients, 8 who underwent the embedded catheter technique did not have externalised catheters. Of the 401 remaining patients, catheter patency failure occurred in 25 (6.2%). Technical failure at 12 months after PD catheter placement calculated from cumulative incidence function was 15.3%. On Cox proportional hazards model analysis, serum albumin (hazard ratio (HR) 0.44; 95% confidence interval (CI) 0.27-0.70) and straight type catheter (HR 2.14; 95% CI 1.24-3.69) were the independent risk factors for technique failure. On logistic regression analysis, diabetes mellitus was the only independent risk factor for perioperative infectious complications (odds ratio 2.70, 95% CI 1.30-5.58). The occurrence rate of perioperative complications generally met the audit criteria of the ISPD guidelines. CONCLUSION PD catheter placement in Japan was proven to be safe and appropriate.
