Abstract
INTRODUCTION Due to treatment of end-stage-renal-disease (ESRD), continuous peritoneal dialysis (CAPD) is used in 11% of cases and is associated with several PD-associated infections. METHODS Clinical data on 71 patients with CAPD were evaluated in addition to exit site infections and episodes of acute peritonitis (AP). RESULTS There were 39 men and 32 women. Average age was 61 years when we began CAPD and average time spent on CAPD program was 3.35 years. Illness that dominantly caused ESRD was diabetes (23 patients). Exit site infection was mostly caused by S epidermidis-MRSE and AP was most commonly caused by Staphylococcus sp. group. Most common cause of death was cardiovascular disease. At the end of this study, 9 patients were alive and still on CAPD, 10 were transplanted, 15 switched to HD and 36 died. CONCLUSION Optimal prevention measures and treatment of infectious complications in CAPD is necessary for better treatment possibilities.

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
BACKGROUND Catheter implantation techniques for peritoneal dialysis (PD) have advanced significantly in recent years. We aimed to analyze the survival and associated complications of catheters inserted using a new technique that is guided by ultrasound and fluoroscopy and requires minimal tissue dissection. The procedure was performed by nephrologists in the outpatient basis, we compared these results of the minimally invasive insertion with traditional implantation using trocars. METHODS A total of 152 PD catheters were placed in 152 patients with stage 5 chronic kidney disease; 62.5% of the patients were men, with a mean age of 56.6 ± 18.5 years. The following two methods were used: minimally invasive insertion (MI group, n = 73) and trocar insertion (T group, n = 79). Patients in both the groups were followed prospectively for 26 months from the date of the first implantation. RESULTS Gender, age, and prevalence of diabetes mellitus were not significantly different between the groups, while the body mass index, presence of obesity, and abdominal scars from previous surgeries were higher in the MI group (p = 0.021). The incidence of catheter dysfunction was lower in the MI group compared to group T (6.8% vs 20.3%; p = 0.019). Exit site infection was also lower with the new technique (4.1% vs. 18.9%; p = 0.005). Further, the cumulative incidence of peritonitis also reduced with MI (p = 0.034). Finally, the overall catheter survival at 1 year was 89%, which has been shown as higher in group MI (95% vs 82% in group T; p = 0.025). CONCLUSION The MI technique for catheter insertion showed low complication rates and excellent catheter survival as compared to traditional implantation methods; thus, it may be an alternative method for PD catheter placement.

Abstract
BACKGROUND Peritonitis is a common and serious complication of peritoneal dialysis and is one of the main causes of peritoneal dialysis technique failure and long-term hemodialysis conversion. OBJECTIVES The aim of the review was to identify and clarify peritonitis risk factors and learn about strategies employed at international level to prevent and reduce the occurrence of peritoneal dialysis associated infections and their complications. DESIGN A scoping review. PARTICIPANTS Adults in pertitoneal dialysis. MEASUREMENTS The methodology framework of Arksey and O'Malley and PRISMA for Scoping Reviews guidelines were applied. A search was conducted of PubMed, Scopus and CINAHL using terms to identify peritoneal dialysis -associated risk factors and interventions carried out for the prevention and reduction of peritonitis in adult persons living at home. RESULTS The 17 studies selected were based on work carried out in nine different countries. Eleven articles analysed modifiable risk factors (low educational level, being a foreigner and low adherence to aseptic technique) and non-modifiable risk factors (age and comorbidities) that predispose to peritonitis in peritoneal dialysis. The other six studies applied an intervention to improve the prevalence of peritonitis considering educational practices adapted to patient characteristics and the application of retraining. CONCLUSIONS Personalised patient training and the identification of risk factors for peritonitis are key to reducing complications and enhancing the survival of peritoneal dialysis patients and the effectiveness of the technique.

Abstract
OBJECTIVES Currently, there is no consensus on the optimal timing for the initiation of peritoneal dialysis (PD) after catheter placement. DESIGN Systematic review and meta-analysis. EXACT DATE OF DATA COLLECTION From inception till July 31, 2023. MAIN OUTCOME MEASURES To assess the outcomes and safety of unplanned PD initiation (<14/7 days after catheter insertion) in cohort studies. RESULTS Fifteen studies involving 3054 participants were included. (1) The risk of unplanned initiation of leakage and Obstruction was no difference in both the break-in period (BI) <14 and BI < 7 groups. (2) Catheter displacement was more likely to occur in the emergency initiation group with BI < 7. (3) No significant differences were observed between the two groups regarding infectious complications. (4) There was no difference in transition to HD between patients with BI < 7 and BI < 14 d. CONCLUSION Infectious complications of unplanned initiation of peritoneal dialysis did not differ from planned initiation. Emergency initiation in the BI < 7 group had higher catheter displacement, but heterogeneity was higher. There were no differences in leakage or obstruction in either group. Catheter survival was the same for emergency initiation of peritoneal dialysis compared with planned initiation of peritoneal dialysis and did not increase the risk of conversion to hemodialysis.

Abstract
Instructions Peritoneal dialysis associated peritonitis (PDAP) is a major cause of technique failure in peritoneal dialysis (PD) patients. The purpose of this study is to construct risk prediction models by multiple machine learning (ML) algorithms and select the best one to predict technique failure in PDAP patients accurately. Methods This retrospective cohort study included maintenance PD patients in our center from January 1, 2010 to December 31, 2021. The risk prediction models for technique failure were constructed based on five ML algorithms: random forest (RF), the least absolute shrinkage and selection operator (LASSO), decision tree, k nearest neighbor (KNN), and logistic regression (LR). The internal validation was conducted in the test cohort. Results Five hundred and eight episodes of peritonitis were included in this study. The technique failure accounted for 26.38%, and the mortality rate was 4.53%. There were resignificant statistical differences between technique failure group and technique survival group in multiple baseline characteristics. The RF prediction model is the best able to predict the technique failure in PDAP patients, with the accuracy of 93.70% and area under curve (AUC) of 0.916. The sensitivity and specificity of this model was 96.67 and 86.49%, respectively. Conclusion RF prediction model could accurately predict the technique failure of PDAP patients, which demonstrated excellent predictive performance and may assist in clinical decision making.

Abstract
BACKGROUND Peritonitis is a common cause of hospitalisation and death among patients undergoing peritoneal dialysis. Periodic retraining is recommended to prevent peritonitis, especially in older adults. OBJECTIVES We evaluated the effectiveness of a retraining programme for reducing peritonitis and exit site infection rates in older adults on peritoneal dialysis. The cost-benefit ratio was also calculated. DESIGN A two-arm prospective randomised controlled trial. PARTICIPANTS One hundred and thirty patients aged 55 years or older were recruited. Participants were randomly assigned to the intervention or control group. While both groups received usual care, the intervention group received a retraining programme (a knowledge and practical assessment and a one-on-one retraining session) 90 days after starting home-based continuous ambulatory peritoneal dialysis therapy. MEASUREMENTS The outcomes included peritonitis rate, exit site infection rate and direct medical costs at 180, 270, and 360 days after starting home-based continuous ambulatory peritoneal dialysis therapy. RESULTS No significant differences were found in the baseline characteristics between groups. The peritonitis rates were 0.11 episodes per patient-year in the intervention group versus 0.13 in the control group. The incidence of exit site infection was 20.0% in the intervention group and 12.3% in the control group. The cost-benefit ratio of retraining was 1:9.6. None of the results were statistically significant. CONCLUSIONS The absence of statistical significance may be partly explained by the premature termination of the study. Large-scale multi-centre trials are warranted to examine the effectiveness of retraining. The timing and long-term effects of retraining also need to be examined.

Abstract
BACKGROUND Peritoneal dialysis (PD)-related infections, such as peritonitis, exit site, and tunnel infections, substantially impair the sustainability of PD. Accordingly, PD-related infection is the top-priority research outcome for patients and caregivers. While PD nurse trainers teach patients to perform their own PD, PD training curricula are not standardized or informed by an evidentiary base and may offer a potential approach to prevent PD infections. The Targeted Education ApproaCH to improve Peritoneal Dialysis outcomes (TEACH-PD) trial evaluates whether a standardized training curriculum for PD nurse trainers and incident PD patients based on the International Society for Peritoneal Dialysis (ISPD) guidelines reduces PD-related infections compared to usual training practices. METHODS The TEACH-PD trial is a registry-based, pragmatic, open-label, multi-center, binational, cluster-randomized controlled trial. TEACH-PD will recruit adults aged 18 years or older who have not previously undergone PD training at 42 PD treatment units (clusters) in Australia and New Zealand (ANZ) between July 2019 and June 2023. Clusters will be randomized 1:1 to standardized TEACH-PD training curriculum or usual training practice. The primary trial outcome is the time to the first occurrence of any PD-related infection (exit site infection, tunnel infection, or peritonitis). The secondary trial outcomes are the individual components of the primary outcome, infection-associated catheter removal, transfer to hemodialysis (greater than 30 days and 180 days), quality of life, hospitalization, all-cause death, a composite of transfer to hemodialysis or all-cause death, and cost-effectiveness. Participants are followed for a minimum of 12 months with a targeted average follow-up period of 2 years. Participant and outcome data are collected from the ANZ Dialysis and Transplant Registry (ANZDATA) and the New Zealand Peritoneal Dialysis (NZPD) Registry. This protocol follows the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) guidelines. DISCUSSION TEACH-PD is a registry-based, cluster-randomized pragmatic trial that aims to provide high-certainty evidence about whether an ISPD guideline-informed standardized PD training curriculum for PD nurse trainers and adult patients prevents PD-related infections.

Jaelani TR, Ibrahim K, Jonny J, Pratiwi SH, Haroen H, Nursiswati N, Ramadhani BP. Peritoneal Dialysis Patient Training Program to Enhance independence and Prevent Complications: A Scoping Review. Int J Nephrol Renovasc Dis 2023; 16:207-222. [PMID: 37720493 PMCID: PMC10505035 DOI: 10.2147/ijnrd.s414447] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Accepted: 08/04/2023] [Indexed: 09/19/2023] Open
Abstract
Background Peritoneal dialysis (PD) training is essential to ensure patient independence and prevent life-threatening complications, such as peritonitis. The International Society for Peritoneal Dialysis (ISPD) recommends that every PD unit worldwide implement local PD training programs with the goal of improving self-care capabilities. This scoping review aims to give an overview of recent literature and recommendations on PD training programs aiming to improve the quality of care and outcomes for PD patients. Methods The literature search was conducted using the PC (Population, Concept) approach. The population of interest in this study is PD patients, and the study concept is the PD training program. Several databases were used to conduct the literature search, including PubMed, Science Direct, and CINAHL. The search process began from July 2022 until January 2023. The inclusion criteria for the search included research articles and recommendations. Results The search yielded 22 articles recommending training programs lasting from 5-8 days, with 1-3-hour sessions and a nurse-to-patient ratio of 1:1. A cumulative training time of 15 hours or more is recommended to enhance patient independence and reduce peritonitis rates. Home-based or in-unit PD training, conducted by experienced nurses using adult learning strategies, has shown significant value in improving self-care and preventing peritonitis. Evaluating training outcomes should encompass knowledge, skills, and attitudes, and the impact on peritonitis rates. Training programs should be flexible and consider physiological and psychosocial barriers to achieving the best results. Conclusion There are a variety of strategies for dialysis training concerning duration, session length, patient-to-trainer ratio, timing, methods, location, compliance, and the need for retraining. More evidence is needed to assess the impact of PD patient training programs on self-care capabilities and peritonitis incidence. Future studies should investigate the effects of training programs on compliance, self-efficacy, and patient and nurse perspectives.

Abstract
Peritoneal dialysis is a home based therapy for patients with advanced chronic kidney disease. This method provides adequate clearance of uremic toxins and removal of excess fluid when a proper dialysis prescription is combined with patient adherence. Peritonitis is the most frequent infectious complication among these patients and may render the continuity of the treatment. Training patients and their caregivers have prime importance to provide proper treatment and prevent complications including infectious ones. The training methods before the onset of treatment are relatively well established. However, patients may break the rules in the long term and tend to take shortcuts. So, retraining may be necessary during follow-up. There are no established guidelines to guide the retraining of PD patients yet. This review tends to summarize data in the literature about retraining programs and also proposes a structured program for this purpose.

Abstract
BACKGROUND The role of monitoring serum vancomycin levels during treatment of peritoneal dialysis (PD)-associated peritonitis is controversial. Substantial inter-individual variability may result in suboptimal serum levels despite similar dosing of vancomycin. The published predictors of suboptimal serum vancomycin levels remain limited. METHODS Data were retrospectively collected from 541 patients on continuous ambulatory peritoneal dialysis between 1 January 2018 and 31 December 312019. For gram-positive cocci and culture-negative peritonitis, we adopted a vancomycin administration and monitoring protocol. Short-term adverse outcomes of PD-associated peritonitis, including transfer to haemodialysis, death, persistent infection beyond planned therapy duration and relapse, were observed. The association between trough serum vancomycin levels and short-term adverse outcomes was evaluated. RESULTS Intraperitoneal vancomycin was used in 61 gram-positive cocci or culture-negative peritonitis episodes in 56 patients. Fourteen episodes of short-term adverse outcomes occurred in 12 patients, whose average trough serum vancomycin levels on day 5 of treatment were significantly lower than those who didn't experience any adverse outcomes (8.4 ± 1.7 vs 12.5 ± 4.3 mg/L, p = 0.003). In gram-positive cocci or culture-negative peritonitis patients, those with higher day 5 trough serum vancomycin levels had a lower risk of short-term adverse outcomes (odds ratio: 0.6, 95% confidence interval: 0.4 to 0.9, p = 0.011). Receiver operating charecteristic curve (ROC) analyses showed that the day 5 trough serum vancomycin levels diagnostic threshold value for short-term adverse outcomes was 10.1 mg/L. After adjustments for gender, exchange volume and residual kidney function (RKF), baseline higher peritoneal transport was associated with a suboptimal (<10.1 mg/L) day 5 serum vancomycin level. CONCLUSIONS Serum vancomycin levels are correlated with short-term adverse outcomes of PD-associated peritonitis, and higher peritoneal solute transport status is associated with suboptimal trough serum vancomycin levels on day 5.

Abstract
Introduction Currently, no consensus on optimal renal replacement modality has been reached for end-stage renal disease (ESRD) patients complicated with hemophilia. They may require infusion of coagulation factors during each hemodialysis session. In comparison, peritoneal dialysis (PD) might be preferred considering that coagulation replacement is only required for catheter placement. However, limited data on the safety and efficacy of PD for treating ESRD patients with hemophilia were reported. Methods This is a single-center retrospective cohort study. ESRD patients diagnosed with hemophilia under PD in Peking Union Medical College Hospital from January 1, 1996 to December 31, 2021 were included and followed-up with every month. Their baseline clinical data, catheter insertion procedure, coagulation factor replacement, complications, and outcome were analyzed and compared with general PD patients. Results In total, 8 patients diagnosed with hemophilia were included, all-male, with a mean age of 50.3±13.3 years old. Two were acquired hemophilia A, whereas the rest were hereditary hemophilia A (HHA). Seven patients experienced significant hemoglobin (Hgb) increment after PD. Peritoneal hemorrhage only consisted of a small portion of all hemorrhage. Patients with hemophilia seemed to have lower small solute clearance despite higher baseline peritoneal permeability, and appeared to have increased peritonitis rate than other male PD patients, yet this study is not powered to prove this. Conclusion PD is a safe and effective choice for patients with hemophilia and ESRD requiring dialysis. More studies are required to evaluate this certain rare group of patients.

Abstract
Background The first case of Taralomyces flavus infection in human and peritoneal dialysis (PD) patient after exposure to biocontrol agent fumes is reported here. Case presentation A 77-year-old Thai female farmer with kidney failure presented with peritonitis and PD catheter obstruction from fungal biofilms. The potential root cause of infection was associated with exposure to biocontrol-agent fumes containing pathogen during agricultural work in her garden. This source of infection has not been mentioned previously. Showering and changing clothes right after outdoor activity with a high density of fungal matters or dust should be added to the routine aseptic technique before performing PD bag exchange to prevent the system contamination. Although the patient received early treatment with liposomal amphotericin B, itraconazole, and catheter removal, according to the ISPD Guideline 2016 and the Global Guideline 2021, the outcome was unfavorable. Antifungal susceptibility testing later revealed that the pathogen was only susceptible to voriconazole. Thus, antifungal susceptibility should be tested if the patient fails or slowly responds to the primary antifungal regimen. Conclusions T. flavus peritonitis is reported here after exposure to biocontrol-agent fumes containing the pathogen. This work also alerts and reiterates nephrology peers to be aware of this overlooked source of peritonitis, the exposure to dusty environments, specifically containing biocontrol-agent fumes.

Abstract
We report on the appearance of multiple tense blisters surrounding the exit site of a Tenckhoff catheter in a 79-year-old woman with end-stage renal disease in peritoneal dialysis. The differential diagnoses included a contact allergic or irritative dermatitis to peritoneal dialysis catheter material and antiseptic agents, bacterial infection, and herpes virus infection, but milia were a clue for a subepidermal blistering disease and lead to appropriate investigations. The laboratory findings, the histopathological examination and the direct immunofluorescence assay confirmed the diagnosis of localized bullous pemphigoid. The disorder typically occurs in elderly people and may be related to drugs, hematological malignancies or neurological conditions but it can also be a complication of hemodialysis or peritoneal dialysis.

Abstract
Background The optimal timing of dialysis access placement in individuals with stage 5 CKD is challenging to estimate. Preemptive living donor kidney transplant (LDKT) is the gold-standard treatment for ESKD due to superior graft survival and mortality, but dialysis initiation is often required. Among LDKT recipients, we sought to determine which clinical characteristics were associated with preemptive transplant. Among non-preemptive LDKT recipients, we sought to determine what dialysis access was used, and their duration of use before receipt of living donor transplant. Methods We retrospectively extracted data on 569 LDKT recipients, >18 years old, who were transplanted between January 2014 and July 2019 at UCSF, including dialysis access type (arteriovenous fistula [AVF], arteriovenous graft [AVG], peritoneal dialysis catheter [PD], and venous catheter), duration of dialysis, and clinical characteristics. Results Preemptive LDKT recipients constituted 30% of our cohort and were older, more likely to be White, more likely to have ESKD from polycystic kidney disease, and less likely to have ESKD from type 2 diabetes. Of the non-preemptive patients, 26% used AVF, 0.5% used AVG, 32% used peritoneal catheter, 11% used venous catheter, and 31% used more than one access type. Median (IQR) time on dialysis for AVF/AVG use was 1.86 (0.85-3.32) years; for PD catheters, 1.12 (0.55-1.92) years; for venous catheters, 0.66 (0.23-1.69) years; and for multimodal access, 2.15 (1.37-3.72) years. Conclusions We characterized the dialysis access landscape in LDKT recipients. Venous catheter and PD were the most popular modality in the first quartile of dialysis, and patients using these modalities had shorter times on dialysis compared with those with an AVF. Venous catheter or PD can be considered a viable bridge therapy in patients with living donor availability given their shorter waitlist times. Earlier referral of patients with living donor prospects might further minimize dialysis need.

Abstract
Peritoneal dialysis (PD)-associated peritonitis is a serious complication of PD and prevention and treatment of such is important in reducing patient morbidity and mortality. The ISPD 2022 updated recommendations have revised and clarified definitions for refractory peritonitis, relapsing peritonitis, peritonitis-associated catheter removal, PD-associated haemodialysis transfer, peritonitis-associated death and peritonitis-associated hospitalisation. New peritonitis categories and outcomes including pre-PD peritonitis, enteric peritonitis, catheter-related peritonitis and medical cure are defined. The new targets recommended for overall peritonitis rate should be no more than 0.40 episodes per year at risk and the percentage of patients free of peritonitis per unit time should be targeted at >80% per year. Revised recommendations regarding management of contamination of PD systems, antibiotic prophylaxis for invasive procedures and PD training and reassessment are included. New recommendations regarding management of modifiable peritonitis risk factors like domestic pets, hypokalaemia and histamine-2 receptor antagonists are highlighted. Updated recommendations regarding empirical antibiotic selection and dosage of antibiotics and also treatment of peritonitis due to specific microorganisms are made with new recommendation regarding adjunctive oral N-acetylcysteine therapy for mitigating aminoglycoside ototoxicity. Areas for future research in prevention and treatment of PD-related peritonitis are suggested.

Abstract
BACKGROUND Pre-training peritonitis (PTP), defined as peritonitis that occurred after catheter insertion and before peritoneal dialysis (PD) training, is increasingly recognized as a risk factor for adverse patient outcomes, yet poorly understood with limited studies conducted to date. This study was conducted to identify the associations, microbiologic profiles and outcomes of PTP compared to post-training peritonitis. METHODS This single-centre, case-control study involved patients with kidney failure who had PD as their first kidney replacement therapy and had experienced an episode of PD peritonitis between 1 January 2005 and 31 December 2015. Individuals experiencing their first episode of peritonitis were included in the study and categorized according to whether it occurred pre- or post-training. The primary outcome was peritonitis cure rates and composite outcome of hemodialysis (HD) transfer for ≥30 days or death. The secondary outcomes included catheter removal and refractory peritonitis rates. RESULTS Among 683 patients who received PD for the first time, 121 (17.7%) had PTP while 265 (38.8%) had post-training peritonitis. PTP patients were more likely to have had exit-site infection (ESI) prior to peritonitis (24.8% compared to 17% in the post-training peritonitis group, p = 0.2). Culture-negative peritonitis was significantly more common in the PTP patients (53.7%) than in the post-training group (27.3%, p < 0.001). The cure was achieved in 68.9% of cases and was not significantly different between the PTP and post-training peritonitis groups (66.1% vs. 70.2%; OR 0.83, 95% CI 0.51-1.35). Lower odds of cure were associated with peritonitis caused by moderate and high severity organisms (OR 0.49, 95% CI 0.29-0.85; OR 0.18, 95% CI 0.08-0.43, respectively). Composite outcome of HD transfer or death was more commonly observed among patients with PTP (87.5% vs. 75.8%; OR 2.2, 95% CI 1.20-4.48) in whom significantly shorter median time to HD transfer was observed (PTP 10.7 months vs. post-training peritonitis 21.9 months, p < 0.0001). CONCLUSIONS PTP is a common condition that is highly associated with preceding ESI, is frequently culture-negative and is associated with worse composite outcome of HD transfer or death. PTP rates should be routinely monitored and reported by PD units for continuous quality improvement.

Abstract
Chronic peritoneal dialysis (PD) is an underutilized renal replacement therapy in treating end-stage renal disease that has several advantages over hemodialysis. The success of continuous ambulatory PD is largely dependent on a functional long-term access to the peritoneal cavity. Several methods have been developed to place the PD catheter using both surgical and percutaneous techniques. The purpose of this article is to describe the percutaneous techniques using fluoroscopy guidance and peritoneoscope method. While fluoroscopic method uses fluoroscopy guidance and a guidewire to place the PD catheter, the peritoneoscopic technique utilizes a needlescope to directly visualize the peritoneal space to avoid adhesions and omentum during catheter placement. These percutaneous approaches are minimally invasive procedures that can be performed on an outpatient basis without the need for general anesthesia.

Hu J, Zhang H, Yi B. Peritoneal transport status and first episode of peritonitis: a large cohort study. Ren Fail 2021; 43:1094-1103. [PMID: 34233593 PMCID: PMC8274533 DOI: 10.1080/0886022x.2021.1949350] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 06/17/2021] [Accepted: 06/17/2021] [Indexed: 10/31/2022] Open
Abstract
BACKGROUND Peritonitis is one of the most serious complications of peritoneal dialysis (PD). This study aimed to explore the relationship between peritoneal transport status and the first episode of peritonitis, as well as the prognosis of patients undergoing continuous ambulatory peritoneal dialysis (CAPD). METHOD A retrospective cohort study was conducted, analyzing data of CAPD patients from 1st January 2009, to 31st December 2017. Baseline data within 3 months after PD catheter placement was recorded. Cox multivariate regression analysis was performed to determine the risk factors for the first episode of peritonitis, technique failure and overall mortality. RESULTS A total of 591 patients were included in our analysis, with a mean follow-up visit of 49 months (range: 27-75months). There were 174 (29.4%) patients who had experienced at least one episode of peritonitis. Multivariate Cox regression analysis revealed that a higher peritoneal transport status (high and high-average) (HR 1.872, 95%CI 1.349-2.599, p = 0.006) and hypoalbuminemia (HR 0.932,95% CI 0.896, 0.969, p = 0.004) were independent risk factors for the occurrence of the first episode of peritonitis. In addition, factors including gender (male) (HR 1.409, 95%CI 1.103, 1.800, p = 0.010), low serum albumin (HR 0.965, 95%CI 0.938, 0.993, p = 0.015) and the place of residence (rural) (HR 1.324, 95%CI 1.037, 1.691, p = 0.024) were independent predictors of technique failure. Furthermore, low serum albumin levels (HR 0.938, 95%CI 0.895, 0.984, p = 0.008) and age (>65years) (HR 1.059, 95%CI 1.042, 1.076, p < 0.001) were significantly associated with the risk of overall mortality of PD patients. CONCLUSIONS Baseline hypoalbuminemia and a higher peritoneal transport status are risk factors for the first episode of peritonitis. Factors including male gender, hypoalbuminemia, and residing in rural areas are associated with technique failure, while hypoalbuminemia and age (>65years) are predictors of the overall mortality in PD patients. Nevertheless, the peritoneal transport status does not predict technique failure or overall mortality of PD patients.

Abstract
Background: Catheter-related infections remain a threat in peritoneal dialysis (PD) patients. Attempts to improve catheter insertion techniques and catheter type with best infectious outcomes yield heterogenous results. We seek to determine catheter-related infections in two different types of catheters and its microbiological spectrum. Methods: Retrospective cross-sectional study conducted in Hospital Serdang, Malaysia. We included end-stage renal disease (ESRD) patients who opted for PD and examined catheter-related infections (peritonitis, exit site infection, and tunnel tract infection) and organisms causing these infections. Results: We included 126 patients in this study; 75 patients received the coiled PD catheter (59.5%) and 51 patients received the straight PD catheter (40.5%). The majority of patients were young, under the age of 65 years old (77.3% and 72.5%) in the coiled and straight PD catheter group, respectively, and the main cause of ESRD was diabetes mellitus in both groups (78.7% vs. 92.2%). The demographic and anthropometric data were similar between both groups. Peritonitis rate (0.29 episodes/patient-years vs. 0.31 episodes/patient-years, P value = 0.909), exit site infection rate (0.31 episodes/patient-year vs. 0.37 episodes/patient-year, P value = 0.730), and tunnel tract infection rate (0.02 episodes/patient-year, P value = 0.430) were similar in the coiled versus straight PD catheter groups. The predominant organism causing peritonitis was the gram-negative organism; Escherichia coli and Klebsiella pneumoniae. In exit site and tunnel tract infections, there is a predominance of gram-negative organisms; Pseudomonas aeruginosa and K. pneumoniae. Conclusions: There was no difference in infectious outcomes between the two different types of catheters. Type of organism in both groups was gram-negative.

Abstract
BACKGROUND The effects of training practices on outcomes of patients receiving peritoneal dialysis (PD) are poorly understood and there is a lack of evidence informing best training practices. This prospective cohort study aims to describe and compare international PD training practices and their association with peritonitis. METHODS Adult patients on PD < 3 months participating in the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) were included. Training characteristics (including duration, location, nurse affiliation, modality, training of family members, use of individual/group training, and use of written/oral competency assessments) were reported at patient and facility levels. Hazard ratio for time to first peritonitis was estimated using Cox models, adjusted for selected patient and facility case-mix variables. RESULTS 1376 PD patients from 120 facilities across 7 countries were included. Training was most commonly performed at the facility (81%), by facility-affiliated nurses (87%) in a 1:1 setting (79%). In the UK, being trained by both facility and third-party nurses was associated with reduced peritonitis risk (aHR 0.31, 95% CI 0.15-0.62, vs facility nurses only). However, this training practice was utilized in only 5 of 14 UK facilities. No other training characteristics were convincingly associated with peritonitis risk. CONCLUSIONS There was no evidence to support that peritonitis risk was associated with when, where, how, or how long PD patients are trained.

Structured re-training to reduce peritonitis in a pediatric peritoneal dialysis program: a quality improvement intervention. Pediatr Nephrol 2021; 36:3191-3200. [PMID: 33797581 DOI: 10.1007/s00467-021-05039-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Revised: 02/25/2021] [Accepted: 03/01/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Decline in skills and knowledge among patients and/or caregivers contributes to peritoneal-dialysis (PD)-related peritonitis. Re-training is important, but no guidelines exist. We describe the implementation of a structured re-training program to decrease peritonitis rates. METHODS This is a prospective quality improvement study involving pediatric patients on long-term home automated PD at National University Hospital, Singapore, between 2012 and 2018. With increasing peritonitis rates, systematic root cause analysis was performed, and based on the contributory factors identified, a structured re-training program was implemented from 2015. This was conducted in 5 cycles, each consisting of 4 modules (hand hygiene, exit site care, peritonitis, and PD troubleshooting). RESULTS Peritonitis rates were analyzed in 2 phases: Phase 1 (2012-2014) when no re-training was performed and Phase 2 (2016-2018) after re-training was instituted. Fifty-nine patients were included. Of these, 45 patients were in Phase 1, 32 in Phase 2, and 18 in both phases. Peritonitis rates decreased from 0.37 ± 0.67 episodes per patient-year in Phase 1 to 0.13 ± 0.32 episodes per patient-year in Phase 2. After adjusting for age at kidney failure onset, PD vintage, years of nursing experience, and the average patient-to-nurse ratio over the study period for each patient, the adjusted peritonitis rates decreased by 0.38 episodes per patient-year (95% CI, 0.09 to 0.67, p = 0.011) from Phase 1 to Phase 2. CONCLUSION Despite an improvement in staffing ratio, peritonitis rates only improved significantly after intensive structured re-training was instituted.

Abstract
Exit site infection (ESI) is a leading complication of peritoneal dialysis (PD), at an incidence of 0.6 episodes per year in the United States, and a major risk factor for catheter removal and peritonitis. An estimated 20% of all peritonitis cases are preceded by an ESI, with up to 50% of Staphylococcus aureus peritonitis associated with ESI. Gram-negative ESIs are less associated with succeeding peritonitis than their gram-positive counterparts, though when present, are associated with a lower peritonitis cure rate. The rate of catheter removal for refractory ESI is relatively highest in ESI due to mycobacteria (up to 40%), S. aureus (35%), Pseudomonas aeruginosa (28%), followed by Corynebacterium, Serratia, and fungi. In review of relevant literature, we found no prophylactic benefit of dressings over nondressings, specific antiseptics over normal saline, or topical honey over topical antibiotic prophylaxis, and thus recommend individualized exit site hygiene. We found topical gentamicin effective for prevention of most ESIs, including gram-negative ESIs, and thus recommend consideration of prophylactic topical gentamicin in areas of high gram-negative peritonitis incidence. With long-term use, observational studies detect up to 25% of gram-positive and 14% of gram-negative ESIs may be mupirocin and gentamicin resistant, respectively. We review empiric and targeted ESI management, including indications for ultrasound, anti-VMRSA, anti-Pseudomonal, and anti-mycobacterial antibiotic use, and catheter removal. We recommend further investigation into the earlier use of second-line treatment agents and the utility of treating post-infectious exit site colonization as avenues to decrease refractory and repeat ESI.

Abstract
AbstractApproximately 10 years have passed since the Peritoneal Dialysis Guidelines were formulated in 2009. Much evidence has been reported during the succeeding years, which were not taken into consideration in the previous guidelines, e.g., the next peritoneal dialysis PD trial of encapsulating peritoneal sclerosis (EPS) in Japan, the significance of angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), the effects of icodextrin solution, new developments in peritoneal pathology, and a new international recommendation on a proposal for exit-site management. It is essential to incorporate these new developments into the new clinical practice guidelines. Meanwhile, the process of creating such guidelines has changed dramatically worldwide and differs from the process of creating what were “clinical practice guides.” For this revision, we not only conducted systematic reviews using global standard methods but also decided to adopt a two-part structure to create a reference tool, which could be used widely by the society’s members attending a variety of patients. Through a working group consensus, it was decided that Part 1 would present conventional descriptions and Part 2 would pose clinical questions (CQs) in a systematic review format. Thus, Part 1 vastly covers PD that would satisfy the requirements of the members of the Japanese Society for Dialysis Therapy (JSDT). This article is the duplicated publication from the Japanese version of the guidelines and has been reproduced with permission from the JSDT.

Abstract
INTRODUCTION Endoscopic procedures can provoke peritonitis in patients receiving peritoneal dialysis (PD). The aim of this study was to assess the development of peritonitis after endoscopic procedures in PD patients. METHODS We retrospectively reviewed the data from PD patients who underwent endoscopies in 3 tertiary hospitals between 2008 and 2018. The patients were grouped into nonprophylactic, prophylactic, and prior antibiotic therapy groups. The incidence of peritonitis within 7 days of endoscopy was assessed. We also examined the factors associated with peritonitis. RESULTS There were 1,316 endoscopies performed in 570 PD patients. The peritonitis rate after endoscopy was 3.0%. Specifically, the peritonitis rate was 1.8% for esophagogastroduodenoscopies, 4.2% for the colonoscopy group, and 5.3% for the sigmoidoscopy group. The prior antibiotic therapy group showed a significantly higher risk of peritonitis (odds ratio = 4.6; 95% confidence interval: 2.2-9.6; P < 0.01). Prophylactic antibiotics were not associated with reducing peritonitis. Therapeutic colonoscopies such as polypectomy were associated with an increased risk of developing peritonitis (odds ratio = 6.5; 95% confidence interval: 1.6-25.9). However, biopsies were not associated with an increased risk of peritonitis. DISCUSSION Prophylactic antibiotics did not reduce the risk of peritonitis after endoscopy in PD patients. Therapeutic colonoscopies such as polypectomy and prior antibiotic therapy before endoscopy were associated with an increased risk of peritonitis.

Changes before and after COVID-19 pandemic on the personal hygiene behaviors and incidence of peritonitis in peritoneal-dialysis patients: a multi-center retrospective study. Int Urol Nephrol 2021; 54:411-419. [PMID: 34146219 PMCID: PMC8214068 DOI: 10.1007/s11255-021-02924-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 06/06/2021] [Indexed: 01/24/2023]
Abstract
Background The impact of Coronavirus disease (COVID-19) pandemic and its influence on personal hygiene behaviors and peritonitis rate in peritoneal-dialysis patients is unknown. Methods A multi-center retrospective study was conducted. We reviewed all the cases of peritoneal-dialysis (PD) patients from four major PD centers in Wuhan before and after COVID-19. There were 567 patients enrolled in total. Information was collected on personal hygiene behaviors, basic clinical characteristics, lab results, peritonitis details. We used Chi-square analysis to compare the personal hygiene behaviors, and used Chi-square goodness-of-fit analysis to compare the peritonitis rates before and after COVID-19. Multivariate logistic regression analysis was used to analyze the risk factors for peritonitis rate. Results There were no significant differences on peritonitis rates in six-month period before and after COVID-19 (p = 0.0756, Fig. 2 and Table 3). But Gram-positive infections decreased dramatically (p = 0.0041, Table 4). Personal hygiene behaviors such as length of time for washing hands when performing PD treatment, the frequency of washing hands before PD treatment and six general behaviors had significant differences (P < 0.05 Table 2). The multivariate logistic regression analysis showed never washing hands before PD treatment and serum albumin level were the risk factors of peritonitis during COVID-19 (OR 14.408, 95%CI 3.930 –52.821, P = 0.0002; OR 4.681, 95% CI 1.755 –12.485, P = 0.002, Table 5). Conclusions The COVID-19 pandemic had a significant positive influence on personal hygiene behaviors. Peritonitis rate did not significantly decrease but Gram-positive infections dramatically decreased. Never hand washing before PD treatment and serum albumin were the risk factors for peritonitis. We should emphasize hand washing before PD treatment in training and re-training program.

Abstract
BACKGROUND Given the important role of Sphingosine-1-phosphate (S1P) in maintaining the hemostasis in intestinal barrier function and regulation of inflammation and immune, we hypothesize that S1P might be a biomarker to predict peritonitis in peritoneal dialysis (PD) patients. METHODS In this case-control study, 78 stable, continuous ambulatory peritoneal dialysis patients were enrolled and followed for the episode of PD associated peritonitis. Patients were divided into two groups by whether or not they had peritonitis during follow-up: non-peritonitis (n = 65) and peritonitis (n = 13) group. S1P was analyzed by enzyme-linked immunosorbent assay. Logistic regression analysis was used to assess factors associated with peritonitis. The variables identified by univariable regression models (p < 0.1) were further selected into the multivariable logistic regression model to determine whether they could independently affect peritonitis. RESULTS Patients with peritonitis had a lower level of S1P than that of patients without peritonitis (1.3 ng/mL IQ 0.8, 3.6 ng/mL vs. 2.8 ng/mL IQ 1.5, 5.4 ng/mL, p = 0.018). The peritonitis group had lower serum albumin, lower blood leukocyte, lower hemoglobin and lower platelet count as compared to the non-peritonitis group. Logistic regression analysis showed that S1P (OR = 0.381, 95% CI = 0.171-0.848, p = 0.018), blood leukocyte count (OR = 0.438, 95% CI = 0.207-0.925, p = 0.030), and serum albumin (OR = 0.732, 95% CI = 0.556-0.962, p = 0.025) were independent factors associated with peritonitis in the present PD population. CONCLUSION Our study showed that S1P was an independent determinant of subsequent peritonitis in PD patients. S1P might serve as a biomarker to predict peritonitis in PD patients.

Abstract
Background: The new Family-Community-Hospital (FCH) three-level comprehensive management aimed to improve the efficiency and scale of peritoneal dialysis (PD) to meet the increased population of end-stage renal disease (ESRD). Our study focused on the clinical outcomes, quality of life, and costs evaluation of this model in a multi-center and prospective cohort study. Methods: A total of 190 ESRD patients who commenced PD at Shanghai Songjiang District were enrolled. According to different PD management models, patients were divided into the Family-Community-Hospital three-level management model (n = 90) and the conventional all-course central hospital management model (n = 100). The primary outcome was clinical outcomes of PD. The secondary outcomes were health-related quality of life (HRQOL) and medical costs evaluation. Results: Compared to conventional management, community-based FCH management achieved a similar dialysis therapeutic effect, including dropout rate (p = 0.366), peritonitis rate (p = 0.965), patient survival (p = 0.441), and technique survival (p = 0.589). Follow-up data showed that similar levels of the renal and peritoneal functions, serum albumin, cholesterol and triglyceride, PTH, serum calcium, and phosphorus between the two groups (all p > 0.05). HRQOL survey showed that the FCH management model helped to improve the psychological status of PD patients, including social functioning (p = 0.006), role-emotional (p = 0.032), and mental health (p = 0.036). FCH management also reduced the hospitalization (p = 0.009) and outpatient visits (p = 0.001) and saved annual hospitalization costs (p = 0.005), outpatient costs (p = 0.026), and transport costs (p = 0.006). Conclusions: Compared with conventional management, community-based FCH management achieved similar outcomes, improved psychological health, reduced medical budgets, and thus had a good social prospect.

Abstract
Background Peritonitis is a leading complication of peritoneal dialysis (PD). One strategy that the International Society for Peritoneal Dialysis (ISPD) has used to help mitigate the morbidity and mortality associated with peritonitis is through prevention, including antibiotic prophylaxis utilization in high-risk situations. The aim of this study is to summarize our current understanding of postprocedural peritonitis and discuss the existing data behind periprocedural antibiotic prophylaxis, focusing primarily on PD catheter insertion, dental procedures, colonoscopies, upper endoscopies with gastrostomy, and gynecologic procedures. Summary The ISPD currently recommends intravenous antibiotics prior to PD catheter insertion, colonoscopies, and invasive gynecologic procedures, though prophylaxis has only demonstrated benefit in a prospective, randomized control setting for PD catheter insertion. However, multiple retrospective studies exist that support the use of antibiotic prophylaxis for the other 2 procedures. No specific antibiotic regimen has been established as most optimal to prevent peritonitis for any of the 3 procedures. Antibiotic coverage should include the Enterobacteriaceae family, as well as Gram-positive organisms commonly found on the skin flora for PD catheter insertion, anaerobes for colonoscopies, and common organisms from the urogenital flora in gynecologic procedures. Additionally, the ISPD currently recommends oral amoxicillin prior to dental procedures. There is currently no ISPD recommendation to provide antibiotic prophylaxis prior to an upper endoscopy with or without gastrostomy, though this is a potential area for research. Key Messages PD patients are at high risk for developing peritonitis after typical procedures. Antibiotic prophylaxis is a potential strategy that the ISPD utilizes to prevent these infections. However, further research needs to be done to determine the optimal antibiotic regimen.

Abstract
Peritonitis is a major peritoneal dialysis complication. Despite a high cure rate, relapsing and repeat peritonitis is associated with Tenckhoff catheter biofilm and multiple episodes of peritoneal damage. In relapsing peritonitis, prompt catheter removal is mandatory; otherwise, in repeat peritonitis, there is not a clear indication for catheter removal. It is questionable if the approach to removal should be different. There are few recent data on repeat and relapsing peritonitis microbiology and clinical outcomes since most studies are from the past decade. This study evaluates the microbiology, clinical outcomes, and impact of relapsing and repeat peritonitis on technique survival and the impact of catheter removal in development of further peritonitis episodes by the same microorganism. We developed a single-center retrospective study from 1998 to 2019 that compared repeat and relapsing peritonitis with a control group in terms of causative microorganisms, cure rate, catheter removal, and permanent and temporary transfer to hemodialysis. We also compared repeat and relapsing peritonitis clinical outcomes when Tenckhoff catheter was not removed. Comparing to the control group, the repeat/relapsing group had a higher cure rate (80.4% versus 74.5%, p=0.01) and lower rate of hospitalization (10.9% versus 27.7%, p=0.01). Technique survival was superior in the repeat/relapsing group (log rank = 4.5, p=0.03). Gram-positive peritonitis was more common in the repeat/relapsing group especially Streptococci viridans (43.5% versus 21.3%, p=0.01) and Gram-negatives in the control group (26.6% vs 9.0%, p=0.02). When the Tenckhoff catheter was not removed after a repeat episode, 58.6% developed a new repeat/relapsing episode versus 60.0% in the relapsing group. Although repeat and relapsing peritonitis have a higher cure rate, it leads to further episodes of peritonitis and consequent morbidity. When Tenckhoff catheter was not removed, the probability of another peritonitis episode by the same microorganism is similar in repeat and relapsing peritonitis.

Abstract
Joubert syndrome (JS) is an inherited ciliopathy characterized by a distinctive cerebellar and brain stem malformation which is known as the "molar tooth sign" on axial brain images, hypotonia, and developmental delay. Approximately 25-30% of patients with JS have kidney disease and many of them progress to end-stage kidney disease (ESKD). However, there are few reports on the outcomes of renal replacement therapy (RRT) in patients with JS and ESKD. In this study, we clarified the clinical features, treatment, and outcomes of patients with JS who underwent RRT. We retrospectively analyzed the medical records and clinical characteristics of 11 patients with JS who underwent RRT between June 1994 and July 2019. Data are shown as the median (range). Gene analysis was performed in 8 of the 11 cases, and CEP290 mutations were found in four patients, two had TMEM67 mutations, one had a RPGRIP1L mutation, and one patient showed no mutation with the panel exome analysis. Complications in other organs included hydrocephalus in two cases, retinal degeneration in eight cases, coloboma in one case, liver diseases in four cases, and polydactyly in one case. Peritoneal dialysis (PD) was introduced in seven cases, with a median treatment duration of 5.4 (3.4-10.7) years. Hemodialysis was performed using arteriovenous fistula in two cases, and kidney transplantation was performed 9 times in eight cases. Only one of the grafts failed during the observation period of 25.6 (8.2-134.2) months. The glomerular filtration rate at the final observation was 78.1 (41.4-107.7) mL/min/1.73 m2. The median age at the final observation was 13.4 (5.6-25.1) years, and all patients were alive except one who died of hepatic failure while on PD. Any type of RRT modality can be a treatment option for patients with JS and ESKD.

Abstract
This article is part of a series, Supporting Family Caregivers: No Longer Home Alone, published in collaboration with the AARP Public Policy Institute. Results of focus groups, conducted as part of the AARP Public Policy Institute's No Longer Home Alone video project, supported evidence that family caregivers aren't given the information they need to manage the complex care regimens of family members. This series of articles and accompanying videos aims to help nurses provide caregivers with the tools they need to manage their family member's health care at home. Nurses should read the articles first, so they understand how best to help family caregivers. Then they can refer caregivers to the informational tear sheet-Information for Family Caregivers-and instructional videos, encouraging them to ask questions. For additional information, see Resources for Nurses.

Abstract
BACKGROUND AND OBJECTIVES Glomerulonephritis (GN) is one of the main causes of chronic terminal kidney disease; however, few studies assess its prognosis in dialysis. We analyze the survival and characteristics of patients on peritoneal dialysis (PD) with primary GN (PGN), and compare their results with other kidney patients. METHODS This prospective observational study took place from 1995 to 2014. We included all incident patients who were initiated on the technique in the Levante registry. Data were transferred to an anonymized database in Access. Statistical analysis was performed using SPSS software (version 19.0). RESULTS The study included 2243 patients, with GN representing the main cause of primary kidney disease (21,5%). IgA nephropathy was the most frequent histologically confirmed form of PGN. Compared with the rest of the sample, patients with PGN were more often men (65% vs 58%, p = .004), and they were on average younger (48 years vs 55 years, p < .001). They also had fewer comorbidities and a higher rate of inclusion on the waitlist for a kidney transplant (87 vs 63%, p < .001). Patients with PGN also had more transplants (48,9%, p < .001), and this was the most frequent reason for stopping PD; beyond that, their peritonitis mean rate was lower (0,34 vs 0,45 episodes/patient-year, p < .001). Technique survival was 90,6% at one year, 71,7% at 3 years, and 59,0% at 5 years (median 76,8 months); there were no differences between groups. Survival was 94,9% at one year, 80,1% at 3 years, and 63,7% at 5 years (median 90,7 months). Patients with PGN showed better mean survival than patients with other kidney pathologies (153,5 months [95% IC: 137,0-169,9] vs 110,3 months [95% CI: 100,8-119,7], p < .001). In the multivariable analysis, the main negative risk factor influencing technique survival was a higher peritoneal transport (p = .018). Factors with a negative influence on mortality were being older (p < .001) and having any comorbidity, mainly diabetes and liver disease (p < .001). By contrast, protective survival factors were inclusion on the transplant waitlist and a higher baseline residual renal function (p = .001). CONCLUSIONS PD has several advantages as a first dialytic treatment, and our results suggest that it is an excellent technique to manage patients with PGN while they await a kidney transplant.

Abstract
Objective In patients on peritoneal dialysis (PD), it was reported that colonoscopy, but not upper gastrointestinal endoscopy, could cause peritonitis as a complication. A guideline of the International Society for Peritoneal Dialysis recommends preemptive intravenous antibiotics administration of ampicillin and aminoglycoside with or without metronidazole, to prevent colonoscopy-associated peritonitis. In this study, we retrospectively evaluated the effects of preemptive antibiotics therapy by oral administration instead of intravenous administration. Methods We investigated the incidence of colonoscopy-associated peritonitis in a single center. In 170 patients undergoing PD between January 2010 and December 2019, 50 colonoscopies were performed, including 49 with oral administration of amoxicillin and ciprofloxacin and/or metronidazole as preemptive therapy 1 hour before the colonoscopy procedure, and 1 without. Results We observed no incidence of colonoscopy-associated peritonitis. Conclusion Generally, oral administration of preemptive antibiotics is less painful and more convenient than intravenous administration, especially in outpatient procedures, such as a colonoscopy. Our results suggest that oral antibiotic administration might be effective for preventing colonoscopy-associated peritonitis in PD patients.

Abstract
Abstract
Background
Peritonitis is a common and clinically important complication in patients receiving peritoneal dialysis (PD). Antibiotic administration is essential for PD-related peritonitis, but routes of administration have not been established enough. Here, we performed a systematic review to assess the efficacy and safety of intraperitoneal (IP) antibiotic administration compared to intravenous (IV) antibiotic administration in patients with PD-related peritonitis.
Methods
Cochrane CENTRAL, MEDLINE, and Ichushi-Web were searched in June 2017. Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed, and articles were screened by four independent reviewers.
Results
Two randomized controlled trials (113 patients) were identified. IP antibiotic administration was more effective than IV antibiotic administration. The pooled risk difference between IP and IV was 0.13 (95% CI − 0.17 to 0.43). Safety assessment indicated less frequency of side effects in patients receiving IP antibiotic administration. The pooled risk ratios of IV to IP regarding adverse drug reaction-related and administration route-related side effects were 5.13 (0.63 to 41.59) and 3.00 (0.14 to 65.90), respectively.
Conclusion
The systematic review and meta-analysis suggested that IP antibiotic administration is more effective and safer in patients with PD-related peritonitis compared to IV antibiotic administration.

Abstract
OBJECTIVES The primary objective of the Peritoneal Dialysis Telemedicine-assisted Platform Cohort (PDTAP) Study is to explore potential predictors and their effects on patient survival, technique survival, and the occurrence of infectious and noninfectious complications. DESIGN The PDTAP study is a national-level cohort study in China. A newly developed PD telemedicine application provided a unique and convenient way to collect multicenter, structured data across units. SETTING The PDTAP study was underway in 27 hospitals from 14 provinces located at 7 geographical regions (northwest, northeast, north, central, southwest, southeast, and south) in China. PARTICIPANTS Our study aims to enroll at least 7000 adult patients with end-stage renal disease receiving PD. METHODS Approval has been obtained through the ethics committees of all hospitals. All participants signed the informed consent form after the center had received ethics board approval in accordance with the Declaration of Helsinki. MAIN OUTCOME MEASURES Patient survival, technique survival, hospitalization, and the occurrence of infectious and noninfectious complications. CONCLUSIONS The PDTAP study aims to explore potential predictors and their effects on patient survival, technique survival, and infectious and noninfectious complications using a newly developed PD telemedicine system to collect multicenter, structured data in real-world practice. Substantial and transformable findings in relation to PD practices were expected. This study also developed a national-level infrastructure for further collaboration and ancillary investigation.

Abstract
We report the first case of peritoneal dialysis (PD) patients with peritonitis from Hortaea werneckii, a halotolerant black yeast-like fungus. The pathogen was confirmed by nucleotide sequences of internal transcribed spacer regions of the ribosomal RNA gene. A potential cause of this infection was tinea nigra on the patient's palm. Therefore, gloving might be advised during PD bag exchange in patients or caregivers who have an obvious lesion of the palm.

Nefrologia 2020; 41:53-61.

Abstract
BACKGROUND AND OBJECTIVES Glomerulonephritis (GN) is one of the main causes of chronic terminal kidney disease; however, few studies assess its prognosis in dialysis. We analyze the survival and characteristics of patients on peritoneal dialysis (PD) with primary GN (PGN), and compare their results with other kidney patients. METHODS This prospective observational study took place from 1995 to 2014. We included all incident patients who were initiated on the technique in the Levante registry. Data were transferred to an anonymized database in Access. Statistical analysis was performed using SPSS software (version 19.0). RESULTS The study included 2,243 patients, with GN representing the main cause of primary kidney disease (21,5%). IgA nephropathy was the most frequent histologically confirmed form of PGN. Compared with the rest of the sample, patients with PGN were more often men (65% vs 58%, P=.004), and they were on average younger (48 years vs 55 years, P<.001). They also had fewer comorbidities and a higher rate of inclusion on the waitlist for a kidney transplant (87 vs 63%, P<.001). Patients with PGN also had more transplants (48,9%, P<.001), and this was the most frequent reason for stopping PD; beyond that, their peritonitis mean rate was lower (0,34 vs 0,45 episodes/patient-year, P<.001). Technique survival was 90,6% at one year, 71,7% at 3 years, and 59,0% at 5 years (median 76,8 months); there were no differences between groups. Survival was 94,9% at one year, 80,1% at 3 years, and 63,7% at 5 years (median 90,7 months). Patients with PGN showed better mean survival than patients with other kidney pathologies (153,5 months [95% IC: 137,0 to 169,9] vs 110,3 months [95% CI: 100,8 to 119,7], P<.001). In the multivariable analysis, the main negative risk factor influencing technique survival was a higher peritoneal transport (P=.018). Factors with a negative influence on mortality were being older (P <.001) and having any comorbidity, mainly diabetes and liver disease (P <.001). By contrast, protective survival factors were inclusion on the transplant waitlist and a higher baseline residual renal function (P=.001). CONCLUSIONS PD has several advantages as a first dialytic treatment, and our results suggest that it is an excellent technique to manage patients with PGN while they await a kidney transplant.

Abstract
OBJECTIVES Early onset peritonitis (EOP) increases the risk of clinical complications in patients initializing peritoneal dialysis (PD). This study aimed to develop and validate a risk prediction model for EOP among patients initializing PD. METHODS 3772 patients registered with the Henan Peritoneal Dialysis Registry (HPDR) between 2007 and 2015 were included. The main outcome, EOP, was defined as incident peritonitis occurring within 6 months of the initialization of PD. Multivariable logistic regression modeling was applied to derive the risk score. All accessible clinical measurements were screened as potential predictors. Assessment of the developed model in terms of model discrimination and calibration was performed using C statistics and a calibration slope, respectively, and validated internally through a bootstrapping (1000-fold) method to adjust for over-fitting. RESULTS The absolute risk of EOP was 14.5%. Age, cardiac function measurements, serum electrolyte test items, lipid profiles, liver function test items, blood urea nitrogen, and white cell count were significant predictors of EOP in the final risk score. Good model discrimination, with C statistics above 0.70, and calibration of agreed observed and predicted risks were identified in the model. CONCLUSION A prediction model that quantifies risks of EOP has been developed and validated. It is based on a small number of clinical metabolic measurements that are available for patients initializing PD in many developing countries, and could serve as a tool to screen the population at high risk of EOP.

Abstract
We present the first reported case of peritoneal dialysis-associated peritonitis caused by Staphylococcus pseudintermedius, an organism that had been misclassified as S. aureus in the past. S. pseudintermedius is well recognized in the veterinary literature and noted as flora in the mouth, nares, and anus of domesticated animals. It has been associated with soft tissue infections in pets and is now being reported in increased frequency as the causative agent in various human infections. It also has a different antibiotic sensitivity profile. The patient had close contact with her pet dog and was successfully treated with intravenous antibiotics in the hospital followed by oral doxycycline for 10 days after discharge. The patient has not had any recurrent infection after obtaining and applying appropriate hygienic education and precautions.

Effects of educational practices on the peritonitis risk in peritoneal dialysis: a retrospective cohort study with data from the French peritoneal Dialysis registry (RDPLF). BMC Nephrol 2020; 21:205.

Abstract
Background Peritoneal dialysis (PD) is a home-based therapy performed by patients or their relatives in numerous cases, and the role of patients’ educational practices in the risk of peritonitis is not well assessed. Our aim was to evaluate the effect of PD learning methods on the risk of peritonitis. Methods This was a retrospective multicentric study based on data from a French registry. All incident adults assisted by family or autonomous for PD exchanges in France between 2012 and 2015 were included. The event of interest was the occurrence of peritonitis. Cox and hurdle regression models were used for statistical analysis to asses for the survival free of peritonitis, and the risk of first and subsequent peritonitis. Results 1035 patients were included. 967 (93%) received education from a specialized nurse. Written support was used for the PD learning in 907 (87%) patients, audio support in 221 (21%) patients, and an evaluation grid was used to assess the comprehension in 625 (60%) patients. In the “zero” part of the hurdle model, the use of a written support and starting PD learning with hands-on training alone were associated with a lower survival free of peritonitis (respectively HR 1.59, 95%CI 1.01–2.5 and HR 1.94, 95%CI 1.08–3.49), whereas in the “count” part, the use of an audio support and starting of PD learning with hands-on training in combination with theory were associated with a lower risk of presenting further episodes of peritonitis after a first episode (respectively HR 0.55, 95%CI 0.31–0.98 and HR 0.57, 95%CI 0.33–0.96). Conclusions The various PD education modalities were associated with differences in the risk of peritonitis. Prospective randomized trials are necessary to confirm causal effect. Caregivers should assess the patient’s preferred learning style and their literacy level and adjust the PD learning method to each individual.

Abstract
Patients receiving peritoneal dialysis (PD) encounter an increased risk for infection, bleeding, and PD fluid leakage after abdominal surgery. These complications may affect the future use of PD. Appropriate patient preparation may mitigate complications. Certain complications or procedures allow patients to remain on PD while others require transition to hemodialysis. We review the etiology and management of infection, bleeding, and PD fluid leakage associated with abdominal surgery as well as the relationship of specific abdominal procedures to continuing PD.

Abstract
Background/aim The aim of this study was to evaluate the clinical outcomes and identify the predictors of mortality in peritoneal dialysis patients. Materials and methods Medical records of all incident peritoneal dialysis (PD) patients followed up between January 2011 and May 2019 were reviewed retrospectively. All patients were followed up until death, renal transplantation, transfer to haemodialysis or the end of the study. Results A total of 242 patients were included in the study. The incidence of peritonitis was 0.18 (ranging from 0 to 14.9) episodes per patient year. Death occurred in 28% (n: 68) of cases. Age, diabetes mellitus, malignancy and refractory heart failure were independent risk factors for all-cause mortality according to multivariate analysis. The presence of comorbid disease and diabetes mellitus and patients aged > 65 years were associated with increased risk of mortality and decreased patient survival. Peritonitis history was associated with increased risk of mortality. Between peritonitis and peritonitis-free group, there was no significant difference in Kaplan-Meier curves in terms of patient survival. Conclusion This is the first study to define 9-year mortality predictors in PD patients in our centre. Although peritonitis is the most feared complication of PD, our study showed that peritonitis did not reduce patient survival.

Abstract
BACKGROUND There has been little research on strategies for prevention of peritoneal dialysis (PD)-related peritonitis. We explored whether regular retraining on bag exchanges (via two methods: technique inspection and oral education) every other month could help reduce the risk of peritonitis in PD patients through a randomized controlled trial (RCT). METHOD This is an RCT conducted at Peking University First Hospital. A total of 150 incident patients receiving PD at our centre were included between December 2010 and June 2016 and followed up until June 2018. Patients were randomly assigned 1:1:1 to receive retraining on bag exchange via technique inspection, oral education or usual care. The primary outcome was time to the first peritonitis episode. Secondary outcomes were time to organism-specific peritonitis, transfer to haemodialysis and all-cause death. RESULTS Patients in the technique inspection group, oral education group and usual care group (n = 50 for each group) were followed up for 47.5 ± 22.9 months. Time to first peritonitis was comparable between the groups. The technique inspection group showed a lower risk of first non-enteric peritonitis than the usual care group, while the oral education group did not show a significant benefit. The incidence of first non-enteric peritonitis in the usual care group (0.07/patient-year) was significantly higher than that in the technique inspection group (0.02/patient-year; P < 0.01) but was comparable with that in the oral education group (0.06/patient-year). Transfer to haemodialysis and all-cause mortality were not significantly different between the groups. CONCLUSIONS Neither technique inspection nor oral education significantly altered the risk of all-cause peritonitis compared with usual care, despite technique inspection showing a trend towards reducing the risk of non-enteric PD-related peritonitis.

Abstract
The purpose of this study is to review the cases of postcolonoscopy appendicitis (PCA) reported in the literature. A comprehensive search using PubMed, EMBASE, Scopus, and Google Scholar identified 57 cases. The median age at presentations of PCA was 55 years. PCAs typically occurred during the first 24 hours after colonoscopy, and the majority developed after diagnostic colonoscopy. Clinical presentations were similar to those with common acute appendicitis, though with a high perforation rate. Most patients were correctly diagnosed using ultrasound or computed tomography scan. Treatment included open appendicectomy, laparoscopic appendicectomy or cecotomy, radiologic drainage of the abscess, nonoperative treatment with antibiotics. In addition to barotrauma, fecalith impaction into the appendiceal lumen, direct trauma to the appendiceal orifice, and underlying ulcerative colitis, a pre-existing subclinical disease of the appendix seems to play an important role in the pathogenesis. For PCA, timely diagnosis and management are crucial to attain a satisfactory outcome.
