One-dose cefuroxime i.v. and i.p. reduces microbial growth in PD patients after catheter insertion

Background. When a peritoneal dialysis catheter is inserted intra-abdominally in a patient starting peritoneal dialysis (PD) there is always a risk for postoperative wound infection and peritonitis. At our centre, PD is started immediately after the dialysis catheter is inserted. This may increase the postoperative risk for peritonitis and wound infection. The aim of this prospective, randomized, study was to evaluate whether the incidence of microbial growth postoperatively (within 10 days) after catheter insertion could be reduced by prophylactic antibiotic therapy. Subjects and methods. During a period of 27 months, 38 patients, who consecutively entered the PD programme, (11 women and 27 men, mean age 57 years) were included in the study. Eighteen patients were given cefuroxime 1.5 g i.v. preoperatively and 350 mg i.p. in the first dialysis bag (containing 1 litre fluid) as prophylaxis. Twenty patients were not given prophylactic antibiotics (control group). All catheter insertions were performed in an operating theatre by the same surgeons using the same technique. Results. In the test group, none of the patients showed microbial growth in the dialysis fluid during the post-operative period, while in the control group six of 20 patients (30%) suffered from such growth (P=0.021) Conclusions. Prophylactic treatment by cefuroxime i.v. pre- an i.p. perioperatively may reduce the risk for microbial growth and peritonitis after insertion of a Tenckhoff catheter.     

Rothia dentocariosa Repeat and Relapsing Peritoneal Dialysis-Related Peritonitis: A Case Report and Literature Review

Peritonitis is well recognized as the Achilles tendon of peritoneal dialysis (PD). Reoccurrence of peritonitis due to the same organism, defined as either repeat or relapsing peritonitis under the 2005 guidelines by the International Society for Peritoneal Dialysis, often results in PD technique failure. Rothia dentocariosa, a low-virulent human oropharynx commensal, is a rarely reported pathogen in human infection, particularly infective endocarditis. R. dentocariosa PD-related peritonitis is exceedingly uncommon yet potentially results in repeat or relapsing peritonitis which requires catheter removal. We report a case of R. dentocariosa repeat and relapsing peritonitis in a PD patient who was treated successfully with antimicrobial therapy.     

Fungal peritonitis in children on peritoneal dialysis

Fungal peritonitis is a rare but serious complication in children on peritoneal dialysis (PD). In this study, risk factors were evaluated, and therapeutic measures were reviewed. A retrospective, multi-centre study was performed in 159 Dutch paediatric PD patients, between 1980 and 2005 (3,573 months). All peritonitis episodes were reviewed. Fungal peritonitis episodes were evaluated based on possible risk factors and treatment strategy. A total of 321 episodes of peritonitis occurred, with 9 cases of fungal peritonitis (2.9%). Candida peritonitis occurred most frequently (78%). Seven patients (78%) had used antibiotics in the prior month. Fungal peritonitis patients had a higher previous bacterial peritonitis rate compared to the total study population (0.13 versus 0.09 episodes/patient*month), with twice as many gram negative organisms. In all fungal peritonitis patients, the PD catheter was removed. In four patients restart on PD was possible. Fungal peritonitis is a rare complication of PD in children, but is associated with high technique failure. The most important risk factors are a high bacterial peritonitis rate, prior use of antibiotics, and previous bacterial peritonitis with gram negative organisms. The PD catheter should be removed early, but in children, peritoneal lavage with fluconazole before removal may be useful to prevent technique failure.     

Candida parapsilosis Peritonitis Has More Complications Than Other Candida Peritonitis in Peritoneal Dialysis Patients

Candida parapsilosis is the most prevalent pathogen of fungal peritonitis in peritoneal dialysis (PD). The difference between C. parapsilosis peritonitis and other C. species for clinical outcomes and treatment responses to fungal peritonitis remains unclear. This retrospective study of fungal peritonitis attempts to answer that question. A total 22 patients with fungal peritonitis in 762 PD patients were enrolled in this study. The mean age of the 22 patients, 9 males and 13 females, was 54.7 ± 12.5 years with a mean PD duration of 39.7 ± 33.4 months. Candida species accounted for 86% (19 cases) of fungal peritonitis and 41% (9 cases) were C. parapsilosis. Thirteen (59%) patients received fluconazole as monotherapy; others received either amphotericin B alone or in combination with fluconazole. Catheters were removed for all patients. The mean duration from peritonitis onset to catheter removal was 5.8 ± 4.1 days. Eleven (50%) patients developed severe complications, with abscess formation or persistent peritonitis after catheter removal. C. parapsilosis peritonitis had a higher complication rate than other Candida species (78% versus 20%, p = 0.012). In patients who received fluconazole as monotherapy, the rate of severe complications of C. parapsilosis peritonitis was statistically higher than those of other Candida species (100% versus 29%, p = 0.013). Because of different severity and prognosis, C. parapsilosis peritonitis in PD patients should be treated more aggressively than other Candida species.     

Paecilomyces variotii peritonitis in an infant on automated peritoneal dialysis

Fungal peritonitis is a serious complication of chronic peritoneal dialysis (CPD) and is frequently associated with CPD drop-out. Paecilomyces variotii, a common saprophytic fungus, rarely causes human infection. To date, only nine adult or adolescent patients with P. variotii peritonitis during continuous ambulatory peritoneal dialysis have been reported. In all patients, successful treatment required antifungal therapy and removal of the peritoneal catheter. We report the first case of P. variotii peritonitis in an infant on automated peritoneal dialysis successfully treated with combined intraperitoneal and oral fluconazole, without removal of the peritoneal catheter.

Acute dialysis-associated peritonitis in children with D+ hemolytic uremic syndrome

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

The changing trends of peritoneal dialysis related peritonitis and novel risk factors

Abstract

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

Mycobacterial peritonitis in pediatric peritoneal dialysis patients

Peritonitis is the most common complication and the leading cause of death in pediatric peritoneal dialysis (PD) patients. According to the most recent data available from the North American Pediatric Renal Transplant Cooperative Study (NAPRTCS), approximately 25% of pediatric PD patients who die succumb to infection. There are no reported cases of Mycobacterium tuberculosis (MTB) or Mycobacterium avium-intracellulare peritonitis in the NAPRTCS registry. With an increasing incidence of MTB worldwide and the impairment of cellular immunity in chronic renal failure patients, it is not surprising that mycobacterium peritonitis can occur in PD patients. We report two pediatric PD patients with mycobacterial peritoneal infection diagnosed over an 11-year period at our institution. One patient presented with a malfunctioning Tenckhoff catheter and again 3 years later with hyponatremia and ascites. The other presented with recurrent culture-negative peritonitis. These cases illustrate the importance of more extensive evaluation of PD complications, to include evaluation for mycobacterium with special media or peritoneal biopsy, in the above clinical settings if the routine work-up is unrevealing.     

A single-center experience on percutaneously performed partial omentectomy in pediatric peritoneal dialysis patients

Objective: This study describes a single-center experience on percutaneously performed partial omentectomy procedure in pediatric peritoneal dialysis (PD) patients who showed early catheter dysfunction and required catheter replacement due to catheter flow obstruction. Materials and methods: We performed a retrospective review of clinical outcomes from pediatric PD patients who underwent percutaneous catheter replacement by pediatric nephrologists between November 1995 and December 2012. Partial omentectomy was performed in those patients in whom omental or adhesion trapping to the catheter tip was seen. Results: During the study period, catheter dysfunction that eventually required percutaneous catheter replacement occurred in 32 (23.7%) children. Of these, 9 patients were performed partial omentectomy. Mean age at initiation of PD and time of omentectomy was 97.48?±?46.06 and 98.53?±?45.55 months, respectively. Catheter dysfunction appeared after a mean 1.20?±?1.0 months. The causes of catheter dysfunction were omental wrapping and malposition. No peritonitis occurred before omentectomy. Mean total operation time was 60?±?8.83?min. No complications were encountered during the procedure. After omentectomy, mean catheter survival period was 5.92?±?6.88 months. A total of five peritonitis episodes occurred. Three patients were transferred to hemodialysis. Six patients were on PD treatment without any problem at the end of the first year of their follow-up. Two patients underwent kidney transplantation. Four patients were still on chronic PD treatment at the end of the study period. Conclusion: When performed by an experienced nephrologist, the performance of partial omentectomy by percutaneous route, when required, is an easy, safe and efficient therapeutic procedure in children on chronic PD treatment.     

Prevention of Peritonitis in Peritoneal Dialysis

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.     

Peritonitis in peritoneal dialysis patients after renal transplantation

Background. The occurrence of peritonitis in peritoneal dialysis patients after renal transplantation during immunosuppression might increase morbidity and mortality. Hence the timing of catheter removal is still controversial. The associated risk factors of this complication have not been analyzed. Methods. We analyzed, retrospectively, the incidence of peritonitis within 90 days after transplantation, its associated morbidity and mortality, as well as risk factors. From 1980 until March 1995, 238 consecutive kidney transplants in peritoneal dialysis patients were performed. Univariate and multivariate logistic regression analysis were used to identify risk factors for the development of peritonitis. Results. 232 cases (141 men, 91 women) were available for analysis. In 191 patients, the catheter was removed with a mean interval after transplantation of 122 days (range 0-573). Thirty peritonitis episodes with predominantly Staphylococcus aureus (10/30) or Gram-negative bacteria (12/30) were observed. Independent risk factors before transplantation were the total number of peritonitis episodes (P<10^-5), previous peritonitis with S. aureus bacteria (P<10^-5), and male sex (P<0.004). Risk factors after transplantation were technical surgical problems (P<10^-5), more than two rejection episodes (P<0.02), permanent graft non-function (P<0.026), and urinary leakage (P<0.035). Conclusions. Transplantation without simultaneous peritoneal catheter removal is feasible. However, this increases the risk of peritonitis after transplantation. Early catheter removal should be considered seriously in those patients at risk. When peritonitis develops, antibiotic treatment should be directed against Gram-positive as well as Gram-negative bacteria until culture results are available.

Comparing long-term outcomes between early and delayed initiation of peritoneal dialysis following catheter implantation

Aim: The aim of this study was to compare peritonitis rates, peritoneal dialysis technique survival and patient survival between patients who started peritoneal dialysis earlier than 14 days (early starters) and 14 days or more (delayed starters) after insertion of a Tenckhoff catheter. Methods: Observational analysis was performed for all patients who underwent insertion of a Tenckhoff catheter at Far Eastern Memorial Hospital between 1 January 2006 and 31 December 2012. The patients were divided into two groups: early and delayed starters. The rate and outcomes of peritonitis were recorded. Peritoneal dialysis technique survival and patient survival were analyzed using the Kaplan–Meier method. Cox regression analysis was performed for peritoneal dialysis technique failure and patient mortality. Results: There were 80 early starters and 69 delayed starters. The peritonitis rate was 0.18 episodes per year in early starters and 0.13 episodes per year in delayed starters. There was no significant difference of peritonitis free survival (p?=?0.146), peritoneal dialysis technique survival (p?=?0.273) and patient survival (p?=?0.739) at 1, 3, 5 years between early starters and delayed starters. After adjustment with age, albumin and diabetes, early starters did not have an increased risk of peritonitis, technique failure and mortality compared to delayed starters. Conclusion: Compared to the patients who started peritoneal dialysis 14 days or more after catheter implantation, the patients who started earlier did not have an increased risk of peritonitis, peritoneal dialysis technique failure and mortality.     

New insights on preventing and managing peritonitis

Methods to prevent peritonitis are an essential component of any successful peritoneal dialysis (PD) program. Careful attention to training of the parents and child on the proper technique of PD and avoidance of manual spiking by using an assist device for the cycler, or use of the double-bag system for continuous ambulatory PD, should decrease risk of peritonitis from touch contamination. Secondly, reduction of peritonitis can be achieved through reduction of exit site infections by use of mupirocin antibiotic cream at the exit site of the PD catheter as part of routine care. If an exit site infection develops and is refractory to therapy, then the PD catheter can be successfully replaced as a single procedure, to reduce the risk of peritonitis. The third step in reducing the risk of peritonitis is to avoid repetitive episodes with the same organism. This may again involve replacing the catheter; as long as the effluent can be cleared, this again can be performed as a single procedure, thus allowing the child to avoid the trauma of hemodialysis. The focus in pediatric PD programs must always be on preserving the peritoneal membrane, and not on preservation of the catheter. With careful attention, peritonitis can become an uncommon event.     

Case Report: Peritonitis by <Emphasis Type="Italic">Penicillium</Emphasis> spp. in a Patient Undergoing Continuous Ambulatory Peritoneal Dialysis

Even though prominent technical improvements in continuous ambulatory peritoneal dialysis (CAPD) treatments during the last decade, peritonitis keeps its place as an important cause of morbidity and mortality in these patients. Among them fungal peritonitis is happened to be the most difficult one to deal with and comes out serious clinical presentation. It is presented here a case of CAPD related fungal peritonitis caused by Penicillium spp. This case experienced recently relapsing bacterial episodes of peritonitis and received long term antibiotics intraperitoneally and systemically. Eventually, Penicillium spp. was detected in several cultures of peritoneal effluent and also tip of Tenckhoff catheter, therefore it was considered as a causative agent. Then, the catheter was removed and amphotericin B therapy was performed. But the general condition of the patient did not improve till surgically drainage of peritoneal collection which was determined by MR (Magnetic Resonance) examination of abdomen after antifungal treatment was completed and Penicillium spp. in the drainage samples was not determined anymore.     

Outcomes of peritoneal dialysis catheter reinsertion: does the cause of initial removal matter?

Purpose

In this study, we aimed to compare patient and technique survival between the patients, in whom peritoneal dialysis (PD) catheter was removed due to severe peritonitis and then it was reinserted, and those, in whom PD catheter was removed due to non-peritonitis causes and then it was reinserted.

Method

Sixty-two patients, in whom PD catheter was reinserted surgically, were retrospectively analyzed in this cohort study. Group 1 consisted of 27 patients in whom PD catheter was removed due to severe peritonitis, whereas Group 2 consisted of 35 patients in whom PD catheter was removed due to non-peritonitis causes.

Results

There was no significant difference between Group 1 and Group 2 in terms of the estimation of overall patient survival [43 months (95 % CI 43.6–83.7) versus 80 months (95 % CI 52.8–107.3, p 0.362]. Similarly, there was no significant difference between Group 1 and Group 2 in terms of the estimation of overall technique survival [82 months (95 % CI 0–166.0) versus 31 months (95 % CI 9.7–52.3), p 0.346].

Conclusion

Our results suggest that there was no significant effect of causes of PD catheter removal (peritonitis vs. non-peritonitis) on the outcomes of PD treatment.     

Longitudinal evaluation of transport kinetics in children receiving peritoneal dialysis

Functional stability of the peritoneal membrane is necessary for maintenance of peritoneal dialysis (PD) as a therapeutic option. Few studies have investigated this issue in children. We evaluated the peritoneal membrane solute transport capacity longitudinally in 26 children (mean age 11.0±5.5 years) receiving long-term PD. Each patient underwent a standardized peritoneal equilibration test on two occasions (mean interval between studies 19.8±5.9 months) to determine solute dialysate to plasma (D/P) ratios, dialysate glucose to initial dialysate glucose (D/D₀) ratios, and mass transfer area coefficients (MTAC). The correlation of transport capacity with peritonitis history was also assessed. No significant change in MTAC, D/P, or D/D₀ values were found when comparing original and follow-up data of the group overall. However, transport of creatinine and glucose was significantly (P<0.05) greater in the peritonitis group compared with the group without peritonitis, and differences in the change over time between the peritonitis groups was significant for MTAC creatinine (P=0.035) and D/D₀ glucose (P=0.020). In summary, this experience demonstrates functional stability of the peritoneal membrane in pediatric patients receiving PD. However, follow-up assessments of peritoneal solute kinetics may be necessary in patients with a history of peritonitis in order to permit early identification of those who may be at risk for ultrafiltration failure and sclerosing peritonitis.

Video-assisted laparoscopic procedures in peritoneal dialysis

Background Although laparoscopy is commonly adopted for the diagnosis and management of various medical or surgical problems, its use for patients with peritoneal dialysis has seldom been addressed. This retrospective study analyzes the indications and clinical effects of this procedure. Methods: A retrospective chart was drawn up and a videotape review performed for 18 laparoscopic procedures involving 198 patients receiving peritoneal dialysis on a long-term basis at our dialysis unit from May 1992 to June 2002. The clinical and demographic parameters in this study included gender, age, underlying renal diseases, duration of peritoneal dialysis before laparoscopy, indications of laparoscopic intervention, laparoscopic findings, time of operation, laparoscopic procedures, postoperative complications, mortality, and catheter results. Results: A total of 18 laparoscopic procedures were performed in 17 uremia patients, with indications including catheter malfunction in five cases, preimplantation evaluation of peritoneal space in three cases, evaluation of the etiology underlying intractable peritonitis in nine cases, and verification of the cause for dialysate leakage in one case. Four (80%) of the five catheter malfunctions were successfully corrected, including one case of catheter migration and three cases of omental wrapping, whereas correction failed in the remaining case because of severe bowel adhesion. New catheter placement after adhesiolysis was successful in all three cases of preimplantation peritoneal evaluation (100%). Of the nine patients whose peritonitis episodes were evaluated, two were found to have secondary peritonitis, two had fungal peritonitis; one had tuberculous peritonitis and four had bacterial peritonitis. In the case of persistent exit-site dialysate leakage, laparoscopy showed a penetrating injury of the abdominal wall, raising a strong suspicion of iatrogenic injury during the tunneling maneuvers in initial catheter placement. Two conversions to laparotomy were performed: one to repair the penetrating injury and the other to save the life of a patient threatened by severe fungal peritonitis with abdominal cocoon formation. The laparoscopic procedures lasted 20 to 150 min (average, 50 min). Despite one instance of postoperative hydrocele, there was no operative mortality. Conclusions: The analytical results of this study demonstrate that the current video-assisted laparoscopic technique is an effective means for managing several problems related to peritoneal dialysis such as catheter malfunction, preimplantation evaluation, location of the source of the dialysate leak, and assessment of the causes for peritonitis. Thus, this technique should always be considered when the these problems arise.     

Nocardia peritonitis and abdominal abscess complicating continuous ambulatory peritoneal dialysis

Peritonitis is a common problem in patients undergoing continuous ambulatory peritoneal dialysis (CAPD) and represents the most frequent cause of peritoneal catheter loss and discontinuation of CAPD. The incidence of peritonitis remains less than one episode per patient year of treatment. Common bacteria, particularly staphyloccal species, are the usual causative agents. Fungi and higher bacteria such as Nocardia as aetiological agents have been infrequent in patients undergoing CAPD. We report a case of Nocardia nova peritonitis complicated by an intra‐abdominal abscess requiring surgical drainage and a protracted course of antibiotics.     

Non-tuberculous mycobacterial PD peritonitis in Australia

Purpose

Peritonitis can be a severe complication of peritoneal dialysis (PD) due to associated morbidity and mortality. Non-tuberculous mycobacteria (NTM) are a rare cause of PD peritonitis, with high rates of catheter removal and conversion to haemodialysis, and a reported mortality as high as 40 %. The incidence, culprit NTM species, and outcomes associated with PD peritonitis have not been described in many countries, including Australia.

Methods

We examined the Australia and New Zealand Dialysis and Transplant Registry from 1 October 2003 to 31 December 2009 for all prevalent peritoneal dialysis patients. Patient characteristics, organisms, treatment and outcome for all NTM PD peritonitis episodes were obtained.

Results

Twelve cases of NTM PD peritonitis were reported, including the first reports of infection due to Mycobacterium hassiacum and Mycobacterium neoaurum. The incidence of NTM PD peritonitis was approximately 1 per 1000 PD patient-years. Recovery occurred in 11 patients, including 3 without removal of their Tenckhoff catheters. A range of antibiotics were utilised. One patient died of sclerosing peritonitis 5 months after diagnosis of PD peritonitis.

Conclusion

Non-tuberculous mycobacteria PD peritonitis is a rare cause of peritonitis, and mortality may be lower than previously reported. Catheter removal occurred in the majority of patients, and adverse outcomes were not observed for those in whom it was retained.     

Catheter revision for the treatment of intractable exit site infection/tunnel infection in peritoneal dialysis patients: A single centre experience

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.
