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.

Abstract
BACKGROUND Malignant pleural effusion (MPE) is a debilitating condition as it commonly causes disabling breathlessness and impairs quality of life (QoL). Indwelling pleural catheter (IPC) offers an effective alternative for the management of MPE. However, IPC-related infections remain a significant concern and there are currently no long-term strategies for their prevention. The Australasian Malignant PLeural Effusion (AMPLE)-4 trial is a multicentre randomised trial that evaluates the use of topical mupirocin prophylaxis (vs no mupirocin) to reduce catheter-related infections in patients with MPE treated with an IPC. METHODS A pragmatic, multi-centre, open-labelled, randomised trial. Eligible patients with MPE and an IPC will be randomised 1:1 to either regular topical mupirocin prophylaxis or no mupirocin (standard care). For the interventional arm, topical mupirocin will be applied around the IPC exit-site after each drainage, at least twice weekly. Weekly follow-up via phone calls or in person will be conducted for up to 6 months. The primary outcome is the percentage of patients who develop an IPC-related (pleural, skin, or tract) infection between the time of catheter insertion and end of follow-up period. Secondary outcomes include analyses of infection (types and episodes), hospitalisation days, health economics, adverse events, and survival. Subject to interim analyses, the trial will recruit up to 418 participants. DISCUSSION Results from this trial will determine the efficacy of mupirocin prophylaxis in patients who require IPC for MPE. It will provide data on infection rates, microbiology, and potentially infection pathways associated with IPC-related infections. ETHICS AND DISSEMINATION Sir Charles Gairdner and Osborne Park Health Care Group Human Research Ethics Committee has approved the study (RGS0000005920). Results will be published in peer-reviewed journals and presented at scientific conferences. TRIAL REGISTRATION Australia New Zealand Clinical Trial Registry ACTRN12623000253606.

Abstract
BACKGROUND AND OBJECTIVE Indwelling pleural catheter (IPC) and indwelling peritoneal catheter (IPeC) have established roles in the management of malignant pleural and peritoneal effusions but catheter-related infections remain a major concern. Topical mupirocin prophylaxis has been shown to reduce peritoneal dialysis catheter infections. This study aimed to assess the (i) compatibility of IPC with mupirocin and (ii) feasibility, tolerability and compliance of topical mupirocin prophylaxis in patients with an IPC or IPeC. METHODS (i) Three preparations of mupirocin were applied onto segments of IPC thrice weekly and examined with scanning electron microscope (SEM) at different time intervals. (ii) Consecutive patients fitted with IPC or IPeC were given topical mupirocin prophylaxis to apply to the catheter exit-site following every drainage/dressing change (at least twice weekly) and followed up for 6 months. RESULTS (i) No detectable structural catheter damage was found with mupirocin applied for up to 6 months. (ii) Fifty indwelling catheters were inserted in 48 patients for malignant pleural (n = 41) and peritoneal (n = 9) effusions. Median follow-up was 121 [median, IQR 19-181] days. All patients tolerated mupirocin well; one patient reported short-term local tenderness. Compliance was excellent with 95.8% of the 989 scheduled doses delivered. Six patients developed catheter-related pleural (n = 3), concurrent peritoneal/local (n = 1) and skin/tract (n = 2) infections from Streptococcus mitis (with Bacillus species or anaerobes), Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa. CONCLUSION This first study of long-term prevention of IPC- or IPeC-related infections found topical mupirocin prophylaxis feasible and well tolerated. Its efficacy warrants future randomized studies.

Abstract
Peritoneal dialysis (PD) is a well-established renal replacement therapy commonly employed in clinical practice. While its primary application is in the treatment of kidney disease, its potential in addressing other systemic disorders, including neurological diseases, has garnered increasing interest. This study provides a comprehensive overview of the related technologies, unique advantages, and clinical applications of PD in the context of neurological disorders. By exploring the mechanism underlying PD, its application in neurological diseases, and associated complications, we addressed the feasibility and benefits of PD as an adjunct therapy for various neurological conditions. Our study aims to highlight its role in detoxification and symptom management, as well as its advantages over other universally accepted methods of renal replacement therapy. Our goal is to bring to the spotlight the therapeutic potential of PD in neurological diseases, such as stroke, stimulate further research, and broaden the scope of its application in the clinical setting.

Abstract
BACKGROUND It has been reported that living far from the peritoneal dialysis (PD) unit is a risk factor for peritonitis. Considering that PD units are urban located; the question of whether living in a rural area compared to an urban area is a risk factor for peritonitis has arisen. METHODS From March 2010 to August 2020, 335 episodes of peritonitis in 202 PD patients followed in a single center were evaluated retrospectively. People living in areas with a population <1000 were defined as living in rural areas regardless of their distance from the PD center. Cox regression analysis was used to identify independent factors associated with peritonitis. RESULTS A total of 202 PD patients were followed during 791 patient-years (mean follow-up of 3.9 years per patient). Total patients had 335 episodes of peritonitis and the rate of peritonitis was 0.42 episodes per year (episodes/patient-year). Cox regression analysis revealed that living environment (urban vs. rural) was not a risk factor for peritonitis (p = 0.57). CONCLUSIONS In Turkey, we report that living in a rural area in our region is not a risk factor for peritonitis. It is not the right approach for both the physician and the patient to be reluctant in the choice of PD due to the concern of peritonitis in rural areas.

Abstract
Multidrug-resistant (MDR) Staphylococcus aureus biofilms have emerged as a serious threat to human health. Recently, the development of antibiotic replacement therapy has gained much attention due to the potential application of bacteriocin. The present study sought to evaluate the antibacterial effect of bacteriocin XJS01 against MDR S. aureus, a previously reported bacteriocin against S. aureus strain 2612:1606BL1486 (S. aureus_26, an MDR strain demonstrated here), and its potential application as an antibiofilm agent. The minimum bactericide concentration of XJS01 against MDR S. aureus_26 was 33.18 μg/mL. XJS01 exhibited excellent storage stability and resistance against acid and reduced the density of established MDR S. aureus_26 biofilm. The hemolytic and HEK293T cytotoxicity activities of XJS01 and the histological analyses in mice confirmed its safety. Moreover, XJS01 effectively disrupted the MDR S. aureus_26 biofilm established on the skin wound surface and reduced the biofilm-isolated bacteria, thereby decreasing the release of pro-inflammatory cytokines and the proliferation of alternatively activated macrophages. Compared to mupirocin, XJS01 exhibited an excellent therapeutic effect on mice skin wounds, confirming it to be a potential alternative to antibiotics.

Continuous ambulatory peritoneal dialysis (CAPD) related peritonitis is a major cause of technique failure, morbidity, and mortality in patients on CAPD. Its prevention and management is key to success of CAPD program. Due to variability in practice, microbiological trends and sensitivity towards antibiotics, there is a need for customized guidelines for management of CAPD related peritonitis (CAPDRP) in India. With this need, Peritoneal Dialysis Society of India (PDSI) organized a structured meeting to discuss various aspects of management of CAPDRP and formulated a consensus agreement which will help in management of patients with CAPDRP.

Abstract
Objetivos: Analizar las infecciones del orificio de salida del catéter peritoneal, identificando los principales factores relacionados con las mismas; asimismo se ha comparado la efectividad de un protocolo basado en la utilización diaria de mupirocina tópica en la cura del orificio de salida frente a la utilización suero salino. Material y Método: Estudio observacional, retrospectivo. Recogimos variables demográficas, clínicas, la etiología y evolución de los episodios de infección del orificio en un periodo de 2 años. Utilizamos un protocolo de profilaxis con suero fisiológico y con mupirocina crema al 2%. Resultados: Estudiamos 75 pacientes, edad media 60,3±13,9 años, 66,7% varones, mediana de tiempo en diálisis peritoneal 24,3 meses (rango intercuartílico 11-48,7). La incidencia de infección del orificio de salida fue del 26,7%, el 77% fueron originadas por microorganismos de piel y mucosas. La infección del orificio de salida se relacionó con el estado portador nasal de Staphylococcus aureus (p=0,048) y la extrusión del dacron externo (p=0,004). De los 4 pacientes que presentaron una peritonitis secundaria a la infección del orificio de salida, 3 fueron trasferidos a hemodiálisis (p=0,025). Con el protocolo de antibioterapia tópica diaria se redujo un 68% la tasa de infecciones. Conclusiones: La exteriorización del anillo externo del catéter peritoneal es un factor predisponente de infecciones. La aplicación diaria de mupirocina es una estrategia efectiva para reducir la incidencia de infección del orificio y peritonitis. La erradicación de portadores nasales de Staphylococcus aureus puede contribuir a reducir la pérdida del catéter y la transferencia a hemodiálisis.

Abstract
Peritonitis caused by Staphylococcusaureus is of major importance in peritoneal dialysis (PD) patients due to its great virulence profile and biofilm formation ability. Bacteriophages are a potential tool to treat peritonitis resulting from biofilm-associated infections. We screened S. aureus colonization in 71 PD patients from the nasal cavity, groin, and PD exit-site regions and analyzed clinical outcomes in these patients. We performed biofilm-formation testing of different strains and compared the isolates of one patient to detect phenotypic differences in S. aureus. Phage cocktails were used to detect S. aureus in vitro susceptibility. An adaptation procedure was performed in cases of bacterial resistance. Around 30% of PD patients (n = 21) were found to be S. aureus carriers; from these, a total of 34 S. aureus strains were isolated, of which 61.8% (n = 21) produced a strong biofilm. Phenotypic differences in strain biofilm production were detected in eight patients out of ten. All strains were sensitive to commonly used antibiotics. Broadly positive phage lytic activity (100%) was observed in six cocktails out of seven, and bacterial resistance towards phages was overcome using adaptation. Overall phages showed a promising in vitro effect in biofilm-forming S. aureus strains.

Abstract
Background The prophylactic application of antimicrobials that are active against Staphylococcus aureus can prevent infections. However, implementation in clinical practice is limited. We have reviewed antimicrobial approaches for the prevention of S. aureus infections. Methods We searched the Cochrane Central Register of Controlled Trials, PubMed/MEDLINE and EMBASE databases and trial registries using synonyms for S. aureus, infections and prevention as search terms. We included randomized controlled trials and systematic reviews only. Results Most studies were conducted with mupirocin. Mupirocin is effective in preventing S. aureus infections in patients receiving dialysis treatment and in surgical patients, particularly if the patients are carriers of S. aureus. The combination of mupirocin and chlorhexidine, but not chlorhexidine alone, is also effective against S. aureus infections. So far, vaccines have not proven successful in protecting against S. aureus infections. Regarding prophylactic povidone-iodine and systemic antibiotics, there is limited evidence supporting their effectiveness against S. aureus infections. Antimicrobial honey has not been proven to be more effective or non-inferior to mupirocin in protecting against S. aureus infections. Conclusions The current evidence supports the use of mupirocin as prophylaxis for preventing infections with S. aureus, particularly in carriers and in the surgical setting or in patients receiving dialysis treatment. Other antimicrobial agents have not been sufficiently proven to be effective so far, or have been proven ineffective. New trials with vaccines and anti-staphylococcal peptides are currently underway and may lead to new preventive strategies in the future.

Abstract
BACKGROUND Peritoneal dialysis (PD)-related infections lead to significant morbidity. The International Society for Peritoneal Dialysis (ISPD) guidelines for the prevention and treatment of PD-related infections are based on variable evidence. We describe practice patterns across facilities participating in the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS). METHODS PDOPPS, a prospective cohort study, enrolled nationally representative samples of PD patients in Australia/New Zealand (ANZ), Canada, Thailand, Japan, the UK and the USA. Data on PD-related infection prevention and treatment practices across facilities were obtained from a survey of medical directors'. RESULTS A total of 170 centers, caring for >11 000 patients, were included. The proportion of facilities reporting antibiotic administration at the time of PD catheter insertion was lowest in the USA (63%) and highest in Canada and the UK (100%). Exit-site antimicrobial prophylaxis was variably used across countries, with Japan (4%) and Thailand (28%) having the lowest proportions. Exit-site mupirocin was the predominant exit-site prophylactic strategy in ANZ (56%), Canada (50%) and the UK (47%), while exit-site aminoglycosides were more common in the USA (72%). Empiric Gram-positive peritonitis treatment with vancomycin was most common in the UK (88%) and USA (83%) compared with 10-45% elsewhere. Empiric Gram-negative peritonitis treatment with aminoglycoside therapy was highest in ANZ (72%) and the UK (77%) compared with 10-45% elsewhere. CONCLUSIONS Variation in PD-related infection prevention and treatment strategies exist across countries with limited uptake of ISPD guideline recommendations. Further work will aim to understand the impact these differences have on the wide variation in infection risk between facilities and other clinically relevant PD outcomes.

Abstract
Abstract
Background
The International Society for Peritoneal Dialysis guidelines recommends the topical application of antibiotics on the exit site for the prevention of peritoneal dialysis (PD)-related infections. However, the recommendation is based on meta-analyses on applying nasal mupirocin ointment or observational or retrospective studies. Here, we evaluated the efficacy of topical application of mupirocin on the exit site for the prevention of PD-related infections.
Methods
We searched the databases, MEDLINE and CENTRAL, documenting the topical application of antibiotics on the exit site in PD patients in April 2017. We included only randomized controlled trials (RCTs) with adult patients wherein the effects of mupirocin were examined. Exit site infection (ESI), peritonitis, and technical failure were assessed as the main outcomes.
Results
Overall, six RCTs were included in this study. It was uncertain whether the application of mupirocin ointment prevents ESI (rate ratio (RR), 0.36; 95% CI, 0.13–1.05), peritonitis (RR 0.78, 95% CI 0.50–1.21), and technical failure (RR, 1.35; 95% CI, 0.25–7.21). Moreover, a comparison between mupirocin and gentamicin showed no difference in the incidence of ESI (RR, 1.14; 95% CI, 0.27–4.81), peritonitis (RR, 0.85; 95% CI, 0.32–2.26), and technical failure (RR, 0.58; 95% CI, 0.28–1.20).
Conclusions
It remains unclear whether topical application of mupirocin on the exit site has any significant effects on PD-related infection or technical failure. Large-scale RCTs with high methodological quality are required to confirm the efficacy of topical application of antibiotics on the exit site.

Abstract
BackgroundClinical practice guidelines aim to reduce the rates of peritoneal dialysis (PD)-related infections, a common complication of PD in end-stage kidney disease patients. We describe the clinical practices used by Australian and New Zealand nephrologists to prevent PD-related infections in PD patients.MethodsA survey of PD practices in relation to the use of antibiotic and antifungal prophylaxis in PD patients was conducted of practicing nephrologists identified via the Australia and New Zealand Society of Nephrology (ANZSN) membership in 2013.ResultsOf 333 nephrologists approached, 133 (39.9%) participated. Overall, 127 (95.5%) nephrologists prescribed antibiotics at the time of Tenckhoff catheter insertion, 85 (63.9%) routinely screened for nasal S. aureus carriage, with 76 (88.4%) reporting they treated S. aureus carriers with mupirocin ointment. Following Tenckhoff catheter insertion, 79 (59.4%) prescribed mupirocin ointment at the exit site or intranasally, and 93 (69.9%) nephrologists routinely prescribed a course of oral antifungal agent whenever their PD patients were given a course of antibiotics.ConclusionsAlthough the majority of nephrologists prescribe antibiotics at the time of Tenckhoff catheter insertion, less than 70% routinely prescribe mupirocin ointment and/or prophylactic antifungal therapy. This variation in practice in Australia and New Zealand may contribute to the disparity in PD-related infection rates that is seen between units.

Abstract
Background The peritonitis rate among children treated with peritoneal dialysis (PD) has not been widely reported in Saudi Arabia. The study aim was to estimate the peritonitis rate per patient-year and investigate the factors associated with higher peritonitis rates in a sample of PD children at King Abdullah Specialist Children’s Hospital-Riyadh (KASCH-R), Saudi Arabia. Methods This retrospective cohort study included 27 PD children treated between September 2007 and December 2017 at KASCH-R. We recorded the children’s demographic and clinical data, and the frequency of peritonitis. Results The 27 PD children reviewed (63% girls; mean age = 7.32 years old; range, 1–14 years), resulted in 86 peritonitis diagnoses in which the overall recurrence rate (in at least one episode) was 58/86 (67.4%) with a 95% confidence interval (CI), 56.5 to 77.2%. The rate of peritonitis episodes per patient-year was 0.76 (1 episode per 1.31 patient-year). The generalized Poisson model identified older children (age > 10 years) (adjusted rate ratios [aRR] = 7.273, 95% CI: 1.562–33.860), congenital nephrosis (aRR = 4.677, 95% CI: 1.443–15.155), height below 3rd percentile (aRR = 4.689, 95% CI: 1.874–11.735), weight below 3rd percentile (aRR = 5.388, 95% CI: 1.678–17.302), low albumin level (aRR = 4.041, 95% CI: 2.053–7.956), two-week duration of antibiotic therapy (aRR = 2.947, 95% CI: 1.163–7.468), which were independently associated with a high peritonitis rate. Conclusions This study showed a high peritonitis rate in our center. Older children, congenital nephrosis, height and weight below the 3rd percentile, low albumin level, and long duration of antibiotic therapy were associated with a higher rate of peritonitis. An optimal peritonitis prevention strategy or best-practice guideline is needed to reduce and prevent peritonitis occurrence in our center.

Trials 2019; 20:754.

Abstract
BACKGROUND Current international guidelines recommend the use of a daily topical exit-site antimicrobial to prevent peritoneal dialysis (PD)-related infections. Although nonantibiotic-based therapies are appealing because they may limit antimicrobial resistance, no controlled trials have been conducted to compare topical antimicrobial agents with usual exit-site care for the prevention of PD-related infections among the Thai PD population. We propose a controlled three-arm trial to examine the efficacy and safety of a daily chlorhexidine gluconate-impregnated patch versus mupirocin ointment versus usual exit-site care with normal saline for the prevention of PD-related infections. METHODS/DESIGNS This study is a randomized, double-blind, multicenter, active-controlled, clinical trial. Adult patients aged 18 years or older who have end-stage kidney disease and are undergoing PD will be enrolled at three PD Centers in Thailand. A total of 354 PD patients will be randomly assigned to either the 2% chlorhexidine gluconate-impregnated patch, mupirocin ointment, or usual exit-site care with normal saline dressing according to a computer-generated random allocation sequence. Participants will be followed until discontinuation of PD or completion of 24 months. The primary study outcomes are time to first PD-related infection (exit-site/tunnel infection or peritonitis) event and the overall difference in PD-related infection rates between study arms. Secondary study outcomes will include (i) the rate of infection-related catheter removal and PD technique failure, (ii) rate of nasal and exit-site Staphylococcus aureus colonization, (iii) healthcare costs, and (iv) skin reactions and adverse events. We plan to conduct a cost-utility analysis alongside the trial from the perspectives of patients and society. A Markov simulation model will be used to estimate the total cost and health outcome in terms of quality-adjusted life years (QALYs) over a 20-year time horizon. An incremental cost-effectiveness ratio in Thai Baht and U.S. dollars per QALYs gained will be illustrated. A series of probabilistic sensitivity analyses will be conducted to assess the robustness of the cost-utility analysis findings. DISCUSSION The results from this study will provide new clinical and cost-effectiveness evidence to support the best strategy for the prevention of PD-related infections among the Thai PD population.

Abstract
BACKGROUND Peritonitis is one of the limiting factors for the growth of peritoneal dialysis (PD) worldwide and is a major cause of technique failure. Several studies have examined the effectiveness of various catheter-related interventions for lowering the risk of PD-related peritonitis. This is an update of a review first published in 2004. OBJECTIVES To evaluate the role of different catheter implantation techniques and catheter types in lowering the risk of PD-related peritonitis in PD patients. SEARCH METHODS We searched the Cochrane Kidney and Transplant Register of Studies up to 15 January 2019 through contact with the Information Specialist using search terms relevant to this review. Studies in the Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal and ClinicalTrials.gov. SELECTION CRITERIA Studies comparing different catheter insertion techniques, catheter types, use of immobilisation techniques and different break-in periods were included. Studies of different PD sets were excluded. DATA COLLECTION AND ANALYSIS Two authors independently assessed study quality and extracted data. Statistical analyses were performed using a random effects model and the results expressed as risk ratio (RR) with 95% confidence intervals (CI). MAIN RESULTS Forty-two studies (3144 participants) were included: 18 evaluated techniques of catheter implantation, 22 examined catheter types, one assessed an immobiliser device, and one examined break-in period. In general, study quality was variable and almost all aspects of study design did not fulfil CONSORT standards for reporting.Catheter insertion by laparoscopy compared with laparotomy probably makes little or no difference to the risks of peritonitis (RR 0.90, 95% CI 0.59 to 1.35; moderate certainty evidence), exit-site/tunnel infection (RR 1.00, 95% CI 0.43 to 2.31; low certainty evidence), catheter removal/replacement (RR 1.20, 95% CI 0.77 to 1.86; low certainty evidence), technique failure (RR 0.71, 95% CI 0.47 to 1.08; low certainty evidence), and death (all causes) (RR 1.26, 95% CI 0.72 to 2.20; moderate certainty evidence). It is uncertain whether subcutaneous burying of catheter increases peritonitis (RR 1.16, 95% CI 0.37 to 3.60; very low certainty evidence). Midline insertion compared to lateral insertion probably makes little or no difference to the risks of peritonitis (RR 0.65, 95% CI 0.32 to 1.33; moderate certainty evidence) and may make little or no difference to exit-site/tunnel infection (RR 0.56, 95% CI 0.12 to 2.58; low certainty evidence). Percutaneous insertion compared with open surgery probably makes little or no difference to the exit-site/tunnel infection (RR 0.16, 95% CI 0.02 to 1.30; moderate certainty evidence).Straight catheters probably make little or no difference to the risk of peritonitis (RR 1.04, 95% CI 0.82 to 1.31; moderate certainty evidence), peritonitis rate (RR 0.91, 95% CI 0.68 to 1.21; moderate certainty evidence), risk of exit-site infection (RR 1.12, 95% CI 0.94 to 1.34; moderate certainty evidence), and exit-site infection rate (RR 1.05, 95% CI 0.77 to 1.43; moderate certainty evidence) compared to coiled catheter. It is uncertain whether straight catheters prevent catheter removal or replacement (RR 1.11, 95% CI 0.73 to 1.66; very low certainty evidence) but straight catheters probably make little or no difference to technique failure (RR 0.82, 95% CI 0.51 to 1.31; moderate certainty evidence) and death (all causes) (RR 0.95, 95% CI 0.62 to 1.46; low certainty evidence) compared to coiled catheter. Tenckhoff catheter with artificial curve at subcutaneous tract compared with swan-neck catheter may make little or no difference to peritonitis (RR 1.29, 95% CI 0.85 to 1.96; low certainty evidence) and incidence of exit-site/tunnel infection (RR 0.96, 95% CI 0.77 to 1.21; low certainty evidence) but may slightly improve exit-site infection rate (RR 0.67, 95% CI 0.50 to 0.90; low certainty evidence). AUTHORS' CONCLUSIONS There is no strong evidence that any catheter-related intervention, including the use of different catheter types or different insertion techniques, reduces the risks of PD peritonitis or other PD-related infections, technique failure or death (all causes). However, the numbers and sizes of studies were generally small and the methodological quality of available studies was suboptimal, such that the possibility that a particular catheter-related intervention might have a beneficial effect cannot be completely ruled out with confidence.

Abstract
Background:The most common complication of peritoneal dialysis (PD) is infection. Despite this, there are no clear guidelines for the management of repeat exit-site infection (ESI), and best practice is not known. We describe our unit's experience of repeat ESI and clinical outcomes in this cohort.Methods:Retrospective case note review of all PD patients with positive ESI swabs at our center between 1 January 2012 and 1 January 2018. Patients were included in the study if they had 2 or more ESI with the same organism within a 12-month period and an initial positive response to antibiotic therapy.Results:Overall, 31 of 248 patients had repeat ESI. The 2 most common causative organisms were Staphylococcus aureus (n = 16, 52%) and Pseudomonas aeruginosa (n = 10, 32%). Twenty (65%) patients developed subsequent peritonitis. The infection resolved with further antibiotics alone in 10 (32%) patients and in 6 patients after PD catheter exchange. The PD catheter was removed in 16 (52%) patients (including 5 after an initial catheter exchange) requiring transfer to hemodialysis (HD). Six (19%) patients died within 12 months of repeat ESI. Both repeat Pseudomonas aeruginosa and Staphylococcus aureus infections were associated with high rates of dialysis modality change (70% and 50%, respectively).Conclusion:We have developed the first definition for repeat ESI. Repeat ESI is clinically important and results in significant morbidity and mortality. Following repeat ESI, peritonitis rates are high and a significant number of patients switch dialysis modality. Studies are needed to determine whether interventions such as early catheter exchange would improve outcomes.

Ther Apher Dial 2019; 24:81-84. [PMID: 31066988 DOI: 10.1111/1744-9987.12836] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2019] [Revised: 05/05/2019] [Accepted: 05/06/2019] [Indexed: 11/30/2022]
Abstract
Topical antibiotic and antiseptic agents have been documented to reduce exit-site infection (ESI) and peritonitis in PD. The aim of this randomized controlled study was to evaluate the efficacy of polyhexanide in the prevention of ESI and peritonitis. Patients were excluded if they had active infection, > 18 years of age, ESI and peritonitis within the previous 4 weeks, received PD for less than 3-months and history of allergy to either drug. All patients were followed up until catheter removal, death, switch to dialysis, transplantation or the end of the study. ESI, tunnel infection, peritonitis, catheter removal and microorganism cause of catheter-related infection were recorded prospectively during clinic follow-up. A total of 88 patients (41 povidone-iodine group; 47 polyhexanide group) were enrolled with a total follow-up duration of 480 and 555 patient-months for povidone-iodine and alternating group, respectively. There were no significant differences in the age, sex, BMI, time of PD, rate of DM, and S. aureus carriage state. A total of 8 ESI and 25 peritonitis episodes were detected during the study. ESI and peritonitis rates tended to be lower in polyhexanide group compared with the povidone-iodine group (0.06 episodes/patient-year vs. 0.12 episodes/patient-year; 0.26 episodes/patient-year vs. 0.32 episodes/patient-year, respectively), but were not significant statistically. Moreover, catheter removal was similar in both groups (0.04 / patient-year vs. 0.05 / patient-year). Polyhexanide is efficient and safe for the prevention of ESI and peritonitis and it may be used as an alternative procedure for the care of healthy exit sites.

Abstract
Peritonitis is a common and severe complication in peritoneal dialysis (PD). Detailed recommendations on the prevention and treatment of PD-associated peritonitis have been published by the International Society for Peritoneal Dialysis (ISPD), but there is a substantial variation in clinical practice among dialysis units. Prophylactic antibiotics administered before PD catheter insertion, colonoscopy, or invasive gynecologic procedures, daily topical application of antibiotic cream or ointment to the catheter exit site, and prompt treatment of exit site or catheter infection are key measures to prevent PD-associated peritonitis. When a patient on PD presents with clinical features compatible with PD-associated peritonitis, empirical antibiotic therapy, with coverage of both Gram-positive and Gram-negative organisms (including Pseudomonas species), should be started once the appropriate microbiologic specimens have been obtained. Intraperitoneal is the preferred route of administration. Antifungal prophylaxis, preferably oral nystatin, should be added to prevent secondary fungal peritonitis. Once the PD effluent Gram stain or culture and sensitivity results are available, antibiotic therapy can be adjusted accordingly. A detailed description on the dosage of individual antibiotic can be found in the latest recommendations by the ISPD. The duration of antibiotics is usually 2-3 weeks, depending on the specific organisms identified. Catheter removal and temporary hemodialysis support is recommended for refractory, relapsing, or fungal peritonitis. In some patients, a new PD catheter could be inserted after complete resolution of the peritonitis. PD catheter removal should also be considered for refractory exit site or tunnel infections. After the improvement in clinical practice, there is a worldwide trend of reduction in PD-associated peritonitis rate, supporting the use of PD as a first-line dialysis modality.

Oral Colonization of Staphylococcus Species in a Peritoneal Dialysis Population: A Possible Reservoir for PD-Related Infections?

Abstract
Peritoneal dialysis-related infections are important morbidity/mortality causes, being staphylococci the most prevalent agents. Since Staphylococcus aureus nasopharynx carriage is a known risk factor for PD infections and the oral cavity is a starting point for systemic diseases development, we aimed at comparing the oral staphylococci colonization between PD patients and controls and studying the association with PD-related infections. Saliva samples were plated in Mannitol salt, and isolates were identified by DnaJ gene sequencing. Staphylococci PD-related infections were recorded throughout the 4-year period following sample collection. Staphylococcus colonization was present in >90% of the samples from both groups (a total of nine species identified). PD patients presented less diversity and less prevalence of multispecies Staphylococcus colonization. Although all patients presenting Staphylococcus epidermidis PD-related infections were also colonized in the oral cavity by the same agent, only 1 out of 7 patients with ESI caused by S. aureus presented S. aureus oral colonization. Staphylococci are highly prevalent in the oral cavity of both groups, although PD patients presented less species diversity. The association between oral Staphylococcus carriage and PD-related infections was present for S. epidermidis but was almost inexistent for S. aureus, so, further studies are still necessary to evaluate the infectious potential of oral Staphylococcus carriage in PD.

Abstract
Peritoneal dialysis is an effective treatment modality for patients with end-stage renal disease. The relative use of peritoneal dialysis versus hemodialysis varies widely by country. Data from a 2004 survey reports the percentage of patients with end-stage renal disease treated with peritoneal dialysis to be 5%-10% in economically developed regions like the US and Western Europe to as much as 75% in Mexico. This disparity is probably related to the availability and access to hemodialysis, or in some cases patient preference for peritoneal over hemodialysis. Peritoneal dialysis-related peritonitis remains the major complication and primary challenge to the long-term success of peritoneal dialysis. Fifty years ago, with the advent of the Tenckhoff catheter, patients averaged six episodes of peritonitis per year on peritoneal dialysis. In 2016, the International Society for Peritoneal Dialysis proposed a benchmark of 0.5 episodes of peritonitis per year or one episode every 2 years. Despite the marked reduction in peritonitis over time, peritonitis for the individual patient is problematic. The mortality for an episode of peritonitis is 5% and is a cofactor for mortality in another 16% of affected patients. Prevention of peritonitis and prompt and appropriate management of peritonitis is essential for the long-term success of peritoneal dialysis in all patients. In this review, challenges and solutions are addressed regarding the pathogenesis, clinical features, diagnosis, treatment, and prevention of peritoneal dialysis-related peritonitis from the viewpoint of an infectious disease physician.

An Ointment Consisting of the Phage Lysin LysGH15 and Apigenin for Decolonization of Methicillin-Resistant Staphylococcus aureus from Skin Wounds. Viruses 2018; 10:v10050244.

Abstract
Staphylococcus aureus (S. aureus) is a common and dangerous pathogen that causes various infectious diseases. Skin damage, such as burn wounds, are at high risk of Staphylococcus aureus colonization and infection, which increases morbidity and mortality. The phage lysin LysGH15 exhibits highly efficient lytic activity against methicillin-resistant S. aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) strains. Apigenin (api) significantly decreases haemolysis of rabbit erythrocytes caused by S. aureus and shows anti-inflammatory function. LysGH15 and api were added to Aquaphor to form an LysGH15-api-Aquaphor (LAA) ointment. The LAA ointment simultaneously exhibited bactericidal activity against S. aureus and inhibited haemolysis. In an LAA-treated mouse model of an MRSA-infected skin wound, the mean bacterial colony count decreased to approximately 102 CFU/mg at 18 h after treatment (and the bacteria became undetectable at 96 h), whereas the mean count in untreated mice was approximately 105 CFU/mg of tissue. The LAA ointment also reduced the levels of pro-inflammatory cytokines (TNF-α, IL-1β, and IFN-γ) and accelerated wound healing in the mouse model. These data demonstrate the potential efficacy of a combination of LysGH15 and api for use as a topical antimicrobial agent against S. aureus.

Abstract
Background Peritonitis is the most serious complication of peritoneal dialysis. Staphylococcus aureus infections could lead to peritonitis which causes reversal of peritoneal dialysis treatment back to hemodialysis. The aim of this study was to develop a controlled release silicone adhesive-based mupirocin patch for prophylactic effect and analyze its antibacterial effectiveness against S. aureus. Methods The matrix patches were prepared by using different polymers, with and without silicone adhesive, dibutyl sebacate and mupirocin. The patches were characterized for mechanical properties, drug content, moisture content, water absorption capacity and Fourier transform infrared spectrum. In vitro release studies were performed by using Franz diffusion cell. In vitro disk diffusion assay was performed on the Mueller–Hinton Agar plate to measure the zone of inhibition of the patches. The in vivo study was performed on four groups of rats with bacterial counts at three different time intervals, along with skin irritancy and histopathologic studies. Results The patches showed appropriate average thickness (0.63–1.12 mm), tensile strength (5.08–10.08 MPa) and modulus of elasticity (21.53–42.19 MPa). The drug content ranged from 94.5% to 97.4%, while the moisture content and water absorption capacities at two relative humidities (75% and 93%) were in the range of 1.082–3.139 and 1.287–4.148 wt%, respectively. Fourier transform infrared spectra showed that there were no significant interactions between the polymer and the drug. The highest percentage of drug release at 8 hours was 47.94%. The highest zone of inhibition obtained was 28.3 mm against S. aureus. The in vivo studies showed that the bacterial colonies were fewer at 1 cm (7×101 CFU/mL) than at 2 cm (1.3×102 CFU/mL) over a 24-hour period. The patches were nonirritant to the skin, and histopathologic results also showed no toxic or damaging effects to the skin. Conclusion The in vitro and in vivo studies indicated that controlled release patches reduced the migration of S. aureus on the live rat skin effectively, however, a longer duration of study is required to determine the effectiveness of the patch on a suitable peritonitis-induced animal model.

Abstract
These guidelines cover all aspects of the care of patients who are treated with peritoneal dialysis. This includes equipment and resources, preparation for peritoneal dialysis, and adequacy of dialysis (both in terms of removing waste products and fluid), preventing and treating infections. There is also a section on diagnosis and treatment of encapsulating peritoneal sclerosis, a rare but serious complication of peritoneal dialysis where fibrotic (scar) tissue forms around the intestine. The guidelines include recommendations for infants and children, for whom peritoneal dialysis is recommended over haemodialysis.Immediately after the introduction there is a statement of all the recommendations. These recommendations are written in a language that we think should be understandable by many patients, relatives, carers and other interested people. Consequently we have not reworded or restated them in this lay summary. They are graded 1 or 2 depending on the strength of the recommendation by the authors, and A-D depending on the quality of the evidence that the recommendation is based on.

Abstract
BACKGROUND Topical antibiotics have been shown to reduce exit-site infection and peritonitis. The aim of this study was to compare infection rates between mupirocin and gentamicin. METHODS Multiple comprehensive databases were searched systematically to include relevant randomized controlled trials and observational studies. Pooled risk ratios (RRs) and 95% confidence intervals were calculated for the incidences of exit-site infection and peritonitis. RESULTS Seven studies (mupirocin group n = 458, gentamicin group n = 448) were analyzed for exit-site infection. The risk of gram-positive exit-site infection was similar between the groups. Gram-negative exit-site infection rate was higher in the mupirocin group (RR = 2.125, P = 0.037). Six studies were assessed the peritonitis risk. There was no difference in the gram-positive and -negative peritonitis rate. CONCLUSIONS Topical use of gentamicin is associated with fewer exit-site infections caused by gram-negative organisms. Gentamicin has comparable efficacy to mupirocin for peritonitis and gram-positive exit-site infection.

Abstract
♦ OBJECTIVE: Prevention of exit-site infection (ESI) is of paramount importance to peritoneal dialysis (PD) patients. The aim of this study was to evaluate the effectiveness of chlorhexidine in the prevention of ESI in incident PD patients compared with mupirocin. ♦ METHODS: This retrospective, pre-test/post-test observational study included all incident PD patients at Singapore General Hospital from 2012 to 2015. Patients received daily topical exit-site application of either mupirocin (2012 - 2013) or chlorhexidine (2014 - 2015) in addition to routine exit-site cleaning with 10% povidone-iodine. The primary outcome was ESI rate during the 2 time periods. Secondary outcomes were peritonitis rate, times to first ESI and peritonitis, hospitalization rate, and infection-related catheter removal. Event rates were analyzed using Poisson regression, and infection-free survival was estimated using Kaplan-Meier and Cox regression survival analyses. ♦ RESULTS: The study included 162 patients in the mupirocin period (follow-up 141.5 patient-years) and 175 patients in the chlorhexidine period (follow-up 136.9 patient-years). Compared with mupirocin-treated patients, chlorhexidine-treated patients experienced more frequent ESIs (0.22 vs 0.12 episodes/patient-year, p = 0.048), although this was no longer statistically significant following multivariable analysis (incidence rate ratio [IRR] 1.78, 95% confidence interval [CI] 0.98 - 3.26, p = 0.06). No significant differences were observed between the 2 groups with respect to time to first ESI (p = 0.10), peritonitis rate (p = 0.95), time to first peritonitis (p = 0.60), hospitalization rate (p = 0.21) or catheter removal rate (0.03 vs 0.04/patient-year, p = 0.56). ♦ CONCLUSIONS: Topical exit-site application of chlorhexidine cream was associated with a borderline significant, higher rate of ESI in incident PD patients compared with mupirocin cream.

Abstract
PURPOSE Although guidelines suggest the routine use of mupirocin or gentamicin at the exit site of PD catheter, our PD unit has been using chlorhexidine gluconate 0.5 % as exit-site care protocol. The aim of this study was to ascertain whether mupirocin application is superior to the traditionally applied chlorhexidine-regarding prevention of exit-site infections and peritonitis in our unit. METHODS Stable incident and prevalent patients of our unit were randomized to apply mupirocin or chlorhexidine at exit site. The study started on July 1, 2010, and continued till December 2014. End point was the first episode of exit-site infection or peritonitis. RESULTS Sixty-two patients (mean age 58.5 ± 14.6 years) were randomized. At the end of follow-up, there were 33 patients on mupirocin treatment and 29 on chlorhexidine. The two groups had no differences in age, sex, PD vintage or PD mode. The only difference between the two groups was the percentage of patients with diabetes, 28 % in chlorhexidine group versus 10 % in mupirocin group. Mean time of follow-up was 28.46 ± 16.37 months. Twenty-four episodes of infections (peritonitis and exit site) were recorded. Time to first infection episode was 32 months in mupirocin group (95 % CI 21.4-42.5) versus 29 months (95 % CI 8.6-49.4) in chlorhexidine group. The Kaplan-Meier survival analysis revealed no difference in the infections between the two protocols (log-rank test, p = 0.477). CONCLUSIONS Mupirocin is not superior in preventing infections comparing with chlorhexidine in this cohort of patients.

Abstract
UNLABELLED ♦ BACKGROUND AND OBJECTIVES Catheter-related infection, namely exit-site infection (ESI) and peritonitis, is a major infectious complication and remains a main cause of technique failure for patients receiving peritoneal dialysis (PD). Topical application of antibiotic cream might reduce catheter-related infection but emergence of resistant or opportunistic organisms could be a concern. Optimal topical agents and regimens remain to be determined. We did a study to examine the effect of an alternating topical antibiotic regimen in preventing catheter-related infection. ♦ METHOD We performed a single-center, randomized, open-label study to compare daily topical application of gentamicin cream with a gentamicin/mupirocin alternate regimen to the exit site. Patients randomized to alternating regimen were asked to have daily application of gentamicin cream in odd months and mupirocin cream in even months. Primary outcomes were ESI and peritonitis. Secondary outcomes were catheter removal or death caused by catheter-related infection. A total of 146 patients (71, gentamicin group; 75, alternating regimen group) were enrolled with a total follow-up duration of 174 and 181 patient-years for gentamicin and alternating groups, respectively. All patients were followed up until catheter removal, death, transfer to another unit, transplantation or the end of the study on March 31, 2014. There were no significant differences in the age, sex, dialysis vintage, and rate of diabetes, helper-assisted dialysis and methicillin-resistant Staphylococcus aureus (MRSA) carriage state. ♦ RESULTS No difference was seen in the time to first ESI or peritonitis. However, the time to first gram-negative peritonitis seemed longer for the gentamicin group (p = 0.055). The 2 groups showed a similar rate of ESI (0.17/yr vs 0.19/yr, p = 0.93) but P. aeruginosa ESI was less common in the gentamicin group (0.06/yr vs 0.11/yr, p < 0.001). There was no difference in the incidence of ESI due to non-tuberculous mycobacteria. Peritonitis rate was significantly lower in the gentamicin group (0.22/yr vs 0.32/yr, p < 0.001), with a striking decrease in gram-negative peritonitis (0.08/yr vs 0.14/yr, p < 0.001), and fungal peritonitis (0.006/yr vs 0.03/yr, p < 0.001), which was all antibiotics-related episodes with antecedent use of systemic antibiotics for the treatment of catheter-related infections. There was no significant difference in the catheter loss or death related to catheter-related infection. ♦ CONCLUSION Alternating gentamicin/mupirocin cream application appeared as effective as gentamicin alone in preventing ESI except for P. aeruginosa. However, it was inferior to gentamicin in the prevention of peritonitis episodes, especially for those caused by gram-negative organisms. It was also not useful in reducing catheter-related infection due to opportunistic organisms but instead associated with a higher incidence of antibiotic-related fungal peritonitis.

Abstract
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. FACTS FROM EAST AND WEST (1) PD is cheaper than HD and provides a better quality of life worldwide, but its prevalence is significantly lower than that of HD in all countries, with the exception of Hong Kong. Allowing reimbursement of PD but not HD has permitted to increase the use of PD over HD in many Asian countries like Hong Kong, Vietnam, Taiwan, Thailand, as well as in New Zealand and Australia over the last years. In the Western world, however, HD is still promoted, and the proportion of patients treated with PD decreases. Japan remains an exception in Asia where PD penetration is very low. Lack of adequate education of practitioners and information of patients might as well be reasons for the low penetration of PD in both the East and West. (2) Patient survival of PD varies between and within countries but is globally similar to HD. (3) Peritonitis remains the main cause of morbidity in PD patients. South Asian countries face specific issues such as high tuberculosis and mycobacterial infections, which are rare in developed Asian and Western countries. The infection rate is affected by climatic and socio-economic factors and is higher in hot, humid and rural areas. (4) Nevertheless, the promotion of a PD-first policy might be beneficial particularly for remote populations in emerging countries where the end-stage renal disease rate is increasing dramatically.

Abstract
UNLABELLED ♦ BACKGROUND Peritoneal catheter tunnel and exit-site infection (TESI) complicates the clinical course of peritoneal dialysis (PD) patients. Adherence to recommendations for catheter insertion, exit-site care, and management of Staphylococcus aureus (SAu) carriage reduces, but does not abrogate the risk of these infections. ♦ OBJECTIVE To reappraise the risk profile for TESI in an experienced center with a long-term focus on management of SAu carriage and a low incidence of these infections. ♦ METHOD Following a retrospective, observational design, we investigated 665 patients incident on PD. The main study variable was survival to the first episode of TESI. We considered selected demographic, clinical, and technical variables, applying multivariate strategies of analysis. ♦ MAIN RESULTS The overall incidence of TESI was 1 episode/68.5 patient-months. Staphylococcus aureus carriage disclosed at inception of PD (but not if observed sporadically during follow-up) (hazard ratio [HR] 1.53, p = 0.009), PD started shortly after catheter insertion (HR 0.98 per day, p = 0.011), PD after kidney transplant failure (HR 2.18, p = 0.017), lower hemoglobin levels (HR 0.88 per g/dL, p = 0.013) and fast peritoneal transport rates (HR 2.92, p = 0.03) portended an increased risk of TESI. Delaying PD ≥ 30 days after catheter insertion markedly improved the probability of TESI. Carriage of methicillin-resistant SAu since the start of PD was associated with a high incidence of TESI by these bacteria. On the contrary, resistance to mupirocin did not predict such a risk, probably due to the use of an alternative regime in affected patients. ♦ CONCLUSIONS Adherence to current recommendations results in a low incidence of TESI in PD patients. Interventions on specific risk subsets have a potential to bring incidence close to negligible levels. Despite systematic screening and management, SAu carriage is still a predictor of TESI. Antibiotic susceptibility patterns may help to refine stratification of the risk of TESI by these bacteria. Early insertion of the peritoneal catheter should be considered whenever possible, to reduce the risk of later TESI.

Abstract
Reducing the frequency of peritonitis for patients undergoing peritoneal dialysis (PD) continues to be a challenge. This review focuses on recent updates in catheter care and other patient factors that influence infection rates. An experienced nursing staff plays an important role in teaching proper PD technique to new patients, but nursing staff must be cognizant of each patient's unique educational needs. Over time, many patients become less adherent to proper dialysis technique, such as washing hands or wearing a mask. This behavior is associated with higher risk of peritonitis and is modifiable with re-training. Prophylactic antibiotics before PD catheter placement can decrease the infection risk immediately after catheter placement. In addition, some studies suggest that prophylaxis against fungal superinfection after antibiotic exposure is effective in reducing fungal peritonitis, although larger randomized studies are needed before this practice can be recommended for all patients. Over time, exit site and nasal colonization with pathogenic organisms can lead to exit-site infections and peritonitis. For patients with Staphylococcus aureus colonization, exit-site prophylaxis with either mupirocin or gentamicin cream reduces clinical infection with this organism. Although there are limited data for support, antibiotic prophylaxis before gastrointestinal, gynecologic, or dental procedures may also help reduce the risk of peritonitis.

Abstract
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, with groups 3 and 4 having the longest duration of treatment, accompanied by a higher percentage of antibiotic switch. Increased resistance to cephradine was found for coagulase-negative Staphylococcus. CONCLUSIONS Peritonitis rates declined significantly over the years because of several changes in PD treatment. However, the need to change the initial antibiotic increased because of diminished antibiotic susceptibility rates over time. Nevertheless, the cure rate was high and remained stable during the entire period analyzed, and the death rate remained low. Consequently, peritonitis is a manageable complication of PD that cannot be considered a contraindication to this mode of renal replacement therapy.

Abstract
BACKGROUND Australians living in rural areas have lower incidence rates of renal replacement therapy and poorer dialysis survival compared with urban dwellers. This study compares peritoneal dialysis (PD) patient characteristics and outcomes in rural and urban Australia. METHODS Non-indigenous Australian adults who commenced chronic dialysis between 1 January 2000 and 31 December 2010 according to the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) were investigated. Each patient's residence was classified according to the Australian Bureau of Statistics remote area index as major city (MC), inner regional (IR), outer regional (OR), or remote/very remote (REM). RESULTS A total of 7657 patients underwent PD treatment during the study period. Patient distribution was 69.0% MC, 19.6% IR, 9.5% OR, and 1.8% REM. PD uptake increased with increasing remoteness. Compared with MC, sub-hazard ratios [95% confidence intervals] for commencing PD were 1.70 [1.61-1.79] IR, 2.01 [1.87-2.16] OR, and 2.60 [2.21-3.06] REM. During the first 6 months of PD, technique failure was less likely outside MC (sub-hazard ratio 0.47 [95% CI: 0.35-0.62], P < 0.001), but no difference was seen after 6 months (sub-hazard ratio 1.05 [95% CI: 0.84-1.32], P = 0.6). Technique failure due to technical (sub-hazard ratio 0.57 [95% CI: 0.38-0.84], P = 0.005) and non-medical causes (sub-hazard ratio 0.52 [95% CI: 0.31-0.87], P = 0.01) was less likely outside MC. Time to first peritonitis episode was not associated with remoteness (P = 0.8). Patient survival while on PD or within 90 days of stopping PD did not differ by region (P = 0.2). CONCLUSIONS PD uptake increases with increasing remoteness. In rural areas, PD technique failure is less likely during the first 6 months and time to first peritonitis is comparable to urban areas. Mortality while on PD does not differ by region. PD is therefore a good dialysis modality choice for rural patients in Australia.

Abstract
BACKGROUND There is a paucity of evidence to guide the best strategy for prevention of peritoneal-dialysis-related infections. Antibacterial honey has shown promise as a novel, cheap, effective, topical prophylactic agent without inducing microbial resistance. We therefore assessed whether daily application of honey at the exit site would increase the time to peritoneal-dialysis-related infections compared with standard exit-site care plus intranasal mupirocin prophylaxis for nasal carriers of Staphylococcus aureus. METHODS In this open-label trial undertaken in 26 centres in Australia and New Zealand, participants undergoing peritoneal dialysis were randomly assigned in a 1:1 ratio with an adaptive allocation algorithm to daily topical exit-site application of antibacterial honey plus standard exit-site care or intranasal mupirocin prophylaxis (only in carriers of nasal S aureus) plus standard exit-site care (control group). The primary endpoint was time to first infection related to peritoneal dialysis (exit-site infection, tunnel infection, or peritonitis). The trial is registered with the Australian New Zealand Clinical Trials Registry, number 12607000537459. FINDINGS Of 371 participants, 186 were assigned to the honey group and 185 to the control group. The median peritoneal-dialysis-related infection-free survival times were not significantly different in the honey (16·0 months [IQR not estimable]) and control groups (17·7 months [not estimable]; unadjusted hazard ratio 1·12, 95% CI 0·83-1·51; p=0·47). In the subgroup analyses, honey increased the risks of both the primary endpoint (1·85, 1·05-3·24; p=0·03) and peritonitis (2·25, 1·16-4·36) in participants with diabetes. The incidences of serious adverse events (298 vs 327, respectively; p=0·1) and deaths (14 vs 18, respectively; p=0·9) were not significantly different in the honey and control groups. 11 (6%) participants in the honey group had local skin reactions. INTERPRETATION The findings of this trial show that honey cannot be recommended routinely for the prevention of peritoneal-dialysis-related infections.

Abstract
BACKGROUND Diabetes mellitus, especially if complicated by poor glycemic control, portends an increased risk of infection. The significance of this association in the case of diabetic patients undergoing peritoneal dialysis (PD) has not been assessed. METHODS Using a retrospective observational design, we analyzed the association between glycemic control at the start of PD (estimated from glycosylated hemoglobin levels) and the risk of peritoneal and catheter tunnel and exit-site infections during follow-up in 183 incident patients on PD. We used the median value of glycosylated hemoglobin to classify patients into good (group A) or poor (group B) glycemic control groups. We applied multivariate strategies of analysis to control for other potential predictors of PD-related infection. RESULTS Groups A and B differed significantly in age, dialysis vintage, use of insulin, and rate of Staphylococcus aureus carriage. Neither the incidence (0.60 episodes in group A vs 0.56 episodes in group B per patient-year) nor the time to a first peritoneal infection (median: 42 months vs 38 months) differed significantly between the study groups. In contrast, group B had a significantly higher incidence of catheter tunnel and exit-site infections (0.23 episodes vs 0.12 episodes per patient-year) and shorter time to a first infection episode (64 months vs 76 months, p = 0.004). The difference persisted in multivariate analysis (adjusted hazard ratio: 2.65; 95% confidence interval: 1.13 to 6.05; p = 0.013). We observed no differences between the study groups in the spectrum of causative organisms or in the outcomes of PD-related infections. CONCLUSIONS Poor glycemic control is a consistent predictor of subsequent risk of catheter tunnel and exit-site infection, but not of peritoneal infection, among diabetic patients starting PD therapy.

Abstract
AIM Catheter-related infection is a major cause of catheter loss in peritoneal dialysis (PD). We evaluated the effect of catheter revision on the treatment of intractable exit site infection (ESI)/tunnel infection (TI) in PD patients who required catheter removal. METHODS We reviewed the medical records of 764 continuous ambulatory peritoneal dialysis (CAPD) patients from May 1995 to April 2011 at our hospital. One hundred and twenty six patients had more than one occurrence of ESI. Catheter revision was performed to treat intractable ESI/TI. Incidence of ESI, causative organisms and the outcomes of catheter revision were analyzed. RESULTS The total PD duration of all patients was 32,581 months. Three hundred and twelve ESI episodes occurred in 126 patients and the incidence of ESI was 1/104 patient-months (0.12/patient-year). The most common causative organism was methicillin-sensitive Staphylococcus aureus (MSSA) (98 episodes), followed by Pseudomonas aeruginosa (63 episodes) and methicillin-resistant S. aureus (MRSA) (28 episodes). Among these, catheter revision was required due to intractable ESI/TI in 36 patients. The most common causative organism was MSSA (14 episodes) followed by P. aeruginosa (10 episodes) and MRSA (six episodes) in catheter revision cases. The outcomes of catheter revision were as follows: ESI relapsed in 11 patients (30.6%) after catheter revision. Among them, five patients were treated with antibiotic treatment, two patients required secondary catheter revision, four patients required catheter removal due to ESI/TI accompanying peritonitis. The catheter survival rate after catheter revision was 89.7% in one year. There were no statistical differences in the rates of ESI relapse after catheter revision between ESI caused by P. aeruginosa (5/10, 50%) and ESI caused by S.aureus (6/21, 28.6%). CONCLUSION Catheter revision may be an alternative treatment option to treat intractable ESI/TI before catheter removal is considered in PD patients.

Abstract
During the past years new developments in peritoneal dialysis (PD) technique have resulted in continuous improvement of patient outcome. The importance of salt and fluid balance, residual renal function and peritoneal glucose load are of increasing interest, whereas small solute clearances have lost importance. In patients with high peritoneal transport rates automated PD (APD) is indicated. However, APD can also be chosen as initial PD treatment since recent studies show comparable or even better survival as compared to continuous ambulatory PD patients. Alternative PD solutions improve peritoneal ultrafiltration (icodextrin), reduce peritoneal glucose load (amino acid solution, icodextrin) and protect the peritoneal membrane (solutions with low concentration of glucose degradation products). Infection risk can be reduced when using antibiotic creams, but resistances should be considered. Ongoing studies will clarify if non-antibiotic agents, e.g. medihoney, are effective in preventing PD-associated infections. Due to these improvements PD and hemodialysis have become equivalent treatments.

Abstract
The peritoneal dialysis (PD)-associated peritonitis caused by fungi is a relatively rare, but very serious disease. PD fluids (PDFs) affect inhibitory efficacy on the microorganisms' growth, which may compromise the affectivity of some antimicrobials. The purpose of this study was to investigate in vitro the fungicidal effectiveness of echinocandins in diverse PDFs. The fungicidal efficacy of caspofungin (CAS), anidulafungin (ANA), micafungin (MYC) against five clinical isolates of Candida albicans was studied in the different PDFs using time-kill curves. As control substance amphotericin B was used. Echinocandins showed slower and reduced killing of C. albicans in PDFs when compared with the time-kill curves in control bouillon. At concentration of 8 × minimal inhibitory concentration (MIC) the greatest reduction in the growth of C. albicans was seen by ANA in lactate-buffered Nutrineal PD4(®) with 1.1% amino acid (2.33 ± 0.52 log10 CFU ml(-1) ), and by CAS and MYC in lactate-buffered Dianeal PD4(®) with 1.36% glucose (2.36 ± 0.89 log10 CFU ml(-1) and 2.36 ± 0.99 log10 CFU ml(-1) respectively). Using high concentration of 128 × MIC echinocandins achieved fungicidal effect in all PDFs. PDFs may significantly impair the activities of echinocandins, but fungicidal activity of drugs can be achieved at high concentration of 128 × MIC.

Abstract
We report 9 cases of exit-site infection and continuous ambulatory peritoneal dialysis peritonitis associated with atypical mycobacteria. All patients had been using topical gentamicin cream as prophylaxis for exit-site infection before the onset of these infections. Gentamicin cream is postulated to be a potential risk factor for atypical mycobacterial infection because of selective pressure on other micro-organisms. The microbiology of atypical mycobacteria and the treatment for atypical mycobacterial infections are discussed.

Abstract
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.

The effects of living distantly from peritoneal dialysis units on peritonitis risk, microbiology, treatment and outcomes: a multi-centre registry study. BMC Nephrol 2012; 13:41. [PMID: 22702659 PMCID: PMC3444345 DOI: 10.1186/1471-2369-13-41] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2012] [Accepted: 06/15/2012] [Indexed: 11/27/2022] Open
Abstract
Background The aim of the study was to determine whether distance between residence and peritoneal dialysis (PD) unit influenced peritonitis occurrence, microbiology, treatment and outcomes. Methods The study included all patients receiving PD between 1/10/2003 and 31/12/2008, using ANZDATA Registry data. Results 365 (6%) patients lived ≥100 km from their nearest PD unit (distant group), while 6183 (94%) lived <100 km (local group). Median time to first peritonitis in distant patients (1.34 years, 95% CI 1.07-1.61) was significantly shorter than in local patients (1.68 years, 95% CI 1.59-1.77, p = 0.001), whilst overall peritonitis rates were higher in distant patients (incidence rate ratio 1.32, 95% CI 1.20-1.46). Living ≥100 km away from a PD unit was independently associated with a higher risk of S. aureus peritonitis (adjusted odds ratio [OR] 1.64, 95% CI 1.09-2.47). Distant patients with first peritonitis episodes were less likely to be hospitalised (64% vs 73%, p = 0.008) and receive antifungal prophylaxis (4% vs 10%, p = 0.01), but more likely to receive vancomycin-based antibiotic regimens (52% vs 42%, p < 0.001). Using multivariable logistic regression analysis of peritonitis outcomes, distant patients were more likely to be cured with antibiotics alone (OR 1.55, 95% CI 1.03-2.24). All other outcomes were comparable between the two groups. Conclusions Living ≥100 km away from a PD unit was associated with increased risk of S. aureus peritonitis, modified approaches to peritonitis treatment and peritonitis outcomes that were comparable to, or better than patients living closer to a PD unit. Staphylococcal decolonisation should receive particular consideration in remote living patients.

Abstract
Peritoneal dialysis used in the treatment of patients with end-stage renal failure is often complicated by peritonitis. Staphylococcus aureus peritonitis is severe, particularly if caused by a methicillin-resistant strain (MRSA). Intraperitoneal administration of drugs for treatment of peritonitis is preferable to intravenous or oral routes because of the resulting higher local antibiotic concentrations. However, peritoneal dialysis fluids (PDFs) have a bacteriostatic effect, which may compromise the efficacy of antibiotics. The bactericidal efficacy of vancomycin, teicoplanin, daptomycin and ceftobiprole was studied in the PDFs Dianeal PD4® (glucose 1.36%), Physioneal 40® (glucose 1.36%), Extraneal® (7.5% icodextrin), and Nutrineal PD4® (1.1% amino acid) using time-kill curves. To simulate in vivo conditions, human serum albumin was added at a final concentration of 2 g/l. All four PDFs had a bacteriostatic effect on the growth of the MRSA test isolate. All antibiotics showed less activity in PDFs compared to control broth. Vancomycin and teicoplanin achieved the greatest reduction in bacterial numbers in the amino-acid containing PDF Nutrineal PD4®. Daptomycin showed its highest activity in Extraneal® and better overall efficacy than the other tested antibiotics. Ceftobiprole showed no killing activities in any of the four PDFs. Based on these in vitro data we conclude that the choice of PDFs for intraperitoneal administration is not trivial and could be crucial for therapy outcome.
