Diabetes Is the Most Critical Risk Factor of Adverse Complications After Peritoneal Dialysis Catheter Placement

Peritoneal Dialysis of Three-Cuff Catheter Experience in Qassim Province, Saudi Arabia

Background: The global rise in noncommunicable diseases, including chronic kidney diseases (CKDs), has led to a significant increase in the use of dialysis units to enhance patient longevity and quality of life. Over time, two-cuff catheters have been replaced by three-cuff catheters, with their usage expanding in nephrology centers across Saudi Arabia. This study aimed to evaluate the benefits, complications, and duration of therapy associated with three-cuff catheters in peritoneal dialysis (PD) patients. Methodology: To ensure the reliability of our results, we conducted a comprehensive cross-sectional study involving 257 patients who underwent three-cuff PD catheter (PDC) insertion and omentopexy. Data were retrospectively collected from 2016 to 2023 at King Fahad Specialist Hospital, Buraidah. The questionnaire was designed based on available variables in the records section and validated by subject experts and experienced research faculty. Data were then entered and analyzed using SPSS version 21.0. Descriptive statistics were employed for inferential statistics, while the chi-square test and logistic regression analysis were used to identify predictors of PD outcomes. Results: The average duration of therapy was 27.84 months, with a standard deviation of 27.23 months. Early complications were minimal, with just 5.1% (n = 13) experiencing peritonitis, 0.8% (n = 2) facing catheter migration, and 0.4% (n = 1 each) encountering omental wrap and exit site infection (ESI) within 30 days of catheter insertion. Remarkably, only 7.8% (n = 20) required catheter reinsertion. In addition, catheter removal due to catheter-related issues was low, affecting only 3.8% of patients. Conclusions: According to the study findings, three-cuff catheters exhibited fewer complications, superior performance, and longer therapy duration. These outcomes may be attributed to the thorough design of the three-cuff catheters, the dedication of the staff, and the implementation of strict policies. To maintain these positive results, it is crucial for the Ministry of Health and the Health Cluster to adopt long-term supportive measures.

Selection of dialysis methods for end-stage kidney disease patients with diabetes

The increasing prevalence of diabetes has led to a growing population of end-stage kidney disease (ESKD) patients with diabetes. Currently, kidney transplantation is the best treatment option for ESKD patients; however, it is limited by the lack of donors. Therefore, dialysis has become the standard treatment for ESKD patients. However, the optimal dialysis method for diabetic ESKD patients remains controversial. ESKD patients with diabetes often present with complex conditions and numerous complications. Furthermore, these patients face a high risk of infection and technical failure, are more susceptible to malnutrition, have difficulty establishing vascular access, and experience more frequent blood sugar fluctuations than the general population. Therefore, this article reviews nine critical aspects: Survival rate, glucose metabolism disorder, infectious complications, cardiovascular events, residual renal function, quality of life, economic benefits, malnutrition, and volume load. This study aims to assist clinicians in selecting individualized treatment methods by comparing the advantages and disadvantages of hemodialysis and peritoneal dialysis, thereby improving patients' quality of life and survival rates.

Educational interventions and identification of risk factors to prevent and reduce peritonitis in peritoneal dialysis: A scoping review

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.

Peritoneal Dialysis-Related Infections

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

A multi-institutional, observational study of outcomes after catheter placement for peritoneal dialysis in Japan

BACKGROUND

This multi-institutional, observational study examined whether the outcomes after peritoneal dialysis (PD) catheter placement in Japan meet the audit criteria of the International Society for Peritoneal Dialysis (ISPD) guideline and identified factors affecting technique survival and perioperative complications.

METHODS

Adult patients who underwent first PD catheter placement for end-stage kidney disease between April 2019 and March 2021 were followed until PD withdrawal, kidney transplantation, transfer to other facilities, death, 1 year after PD start or March 2022, whichever came first. Primary outcomes were time to catheter patency failure and technique failure, and perioperative infectious complications within 30 days of catheter placement. Secondary outcomes were perioperative complications. Appropriate statistical analyses were performed to identify factors associated with the outcomes of interest.

RESULTS

Of the total 409 patients, 8 who underwent the embedded catheter technique did not have externalised catheters. Of the 401 remaining patients, catheter patency failure occurred in 25 (6.2%). Technical failure at 12 months after PD catheter placement calculated from cumulative incidence function was 15.3%. On Cox proportional hazards model analysis, serum albumin (hazard ratio (HR) 0.44; 95% confidence interval (CI) 0.27-0.70) and straight type catheter (HR 2.14; 95% CI 1.24-3.69) were the independent risk factors for technique failure. On logistic regression analysis, diabetes mellitus was the only independent risk factor for perioperative infectious complications (odds ratio 2.70, 95% CI 1.30-5.58). The occurrence rate of perioperative complications generally met the audit criteria of the ISPD guidelines.

CONCLUSION

PD catheter placement in Japan was proven to be safe and appropriate.
