RESUMO
BACKGROUND: The number of patients on peritoneal dialysis (PD) in our hospital has increased during the past 5 years, but the number discontinuing PD has also increased. The purpose of this study was to identify the risk factors for PD discontinuation by analyzing the association between technical survival period (defined as the duration of PD) and various clinical factors. METHODS: We retrospectively investigated 87 patients who were started on PD at our hospital and attended regularly from April 2015 to March 2020, and we analyzed the association between technical survival period and various clinical factors. We also looked for associations between technical survival period and hospitalizations for heart failure, peritonitis, and exit-site infections among patients undergoing PD. RESULTS: The patients using renin-angiotensin-aldosterone system inhibitors (RASi) (P = 0.0218), those with left ventricular ejection fraction (LVEF) > 50% (P = 0.0194) when they started PD, and those with estimated glomerular filtration rate (eGFR) ≥ 6 (mL/min/1.73 m2) (P = 0.0013) at the initiation of PD showed significantly longer technical survival period, and those who were hospitalized for heart failure had significantly shorter period (P = 0.0008). CONCLUSION: Treatment of RASi, LVEF > 50% and eGFR ≥ 6 mL/ min/1.73 m2 when the initiation of PD and better volume control to prevent ultrafiltration failure and heart failure may improve technical survival period in patients undergoing PD.

Background: There are numerous causes of liver function disorder in patients undergoing peritoneal dialysis (PD). Infection with the Hepatitis E virus (HEV) is a rare cause of liver injury, and the behavior of HEV in patients with PD is unclear. Since patients undergoing dialysis are frequently polypharmatic, liver injury caused by HEV infection may be misdiagnosed as drug-induced liver injury. Case Presentation: A 61-year-old woman with PD developed abrupt elevation of blood transaminase levels on a routine outpatient session. Since the patient has been receiving tolvaptan as the only new medication, we suspected tolvaptan induced liver injury. In further investigating the cause of liver injury, the blood screening test was found to be positive for HEV-IgA. The patient was diagnosed with HEV infection, and had a self-limited course. Conclusion: When encountered with patients developing liver injury during PD, HEV infection should be included in the differential diagnosis.
RESUMO
PURPOSE: Peritoneal dialysis (PD)-related peritonitis and lower limb ulcer are the important complications in patients undergoing PD. Although the association between lower limb ulcer and peritonitis in patients undergoing PD is unclear, based on our clinical experience and the clinical importance of the complications in patients undergoing PD, we hypothesized that lower limb ulcer is associated with peritonitis in patients on PD. PATIENTS AND METHODS: In this single center, retrospective cohort study, we studied 87 patients who started undergoing PD at our hospital from April 2015 to March 2020. We compared these 8 patients with lower limb ulcer with the other 79 patients without lower limb ulcer. We compared between the patients in the objection period of this study about peritonitis using Log rank test, and used the unpaired t-test and Fisher's exact test to compare the clinical factors between the two groups. Moreover, we used univariate and multivariate logistic regression analyses to study the association of PD-related peritonitis with the clinical factors. RESULTS: The period developed first peritonitis of the patients on PD with lower limb ulcer was significant shorter than those without lower limb ulcer in Log rank test (P = 0.011). The Fisher's exact test and unpaired t-test showed that the difference in the prevalence of PD-related peritonitis (P = 0.009), peritonitis/patient years (P = 0.036), the BMI (P = 0.007) and icodextrin (P = 0.001) were significant. Lower limb ulcer had significant associations with peritonitis in patients on PD in both univariate [odds ratio (OR) 8.461, 95% confidence interval (CI) 1.854-45.60, P = 0.006] and multivariate [OR 7.169, 95% CI 1.519-39.480, P = 0.013] logistic regression analysis. CONCLUSION: In conclusion, lower limb ulcer may be associated with peritonitis in patients undergoing PD. Further large-scale, prospective studies are required to confirm these results.
RESUMO
BACKGROUND: Peritonitis is one of the most common complications in patients undergoing peritoneal dialysis, (PD) but it is difficult to predict or prevent. In this study, we analyzed the risk of endogenous peritonitis in patients receiving PD. METHODS: We included all patients who underwent PD at our hospital from April 2015 to March 2020. There were 22 cases of peritonitis, including 18 cases of endogenous peritonitis without evidence of exit-site infection or technical failure. We evaluated older age, female sex, obesity, diabetes, diverticulosis, and constipation as potential important risk factors for endogenous peritonitis and included these as confounding factors, along with a current or previous history of smoking, in univariate logistic regression models. RESULTS: A previous or current history of smoking (p = 0.0065) was the most significant risk factor for endogenous peritonitis in the univariate logistic regression model. In addition, smoking was the most significant independent risk factor for endogenous peritonitis (p = 0.0034) in multivariate logistic regression models. Diabetes was also significant in univariate and multivariate logistic regression analysis. CONCLUSIONS: Smoking is a significant independent risk factor for endogenous peritonitis in patients undergoing PD. Cessation of smoking may lower the risk of endogenous peritonitis in this patient group.

Peritonitis is a common complication of peritoneal dialysis (PD) and can result in PD catheter removal, permanent hemodialysis, and, potentially, death. Prediction and prevention of PD-related peritonitis are thus extremely important. In 2016, the International Society for Peritoneal Dialysis published guidelines for patients with peritonitis undergoing PD. The guidelines cover most cases of PD-related peritonitis caused by bacteria and include clear indications for catheter removal. However, difficulties often arise when deciding the timing of catheter removal. When multiple enteric organisms are identified in a culture of dialysis effluent, peritonitis may be caused by intra-abdominal pathology, which is associated with substantial mortality. In such cases, catheter removal is considered. In this report, we describe a case in which, during antibiotic therapy for PD-related peritonitis due to Enterococcus faecalis alone, the patient developed a relapse of peritonitis caused by a newly detected Gram-negative, rod-like Pseudomonas aeruginosa. He required catheter removal because of the possibility of peritonitis recurrence. Although additional study is required, early catheter removal may be effective when a new organism is detected during antibiotic therapy for PD-related peritonitis caused by an organism not meeting the definition of refractory peritonitis.

Low-density lipoprotein apheresis (LDL-A) has been developed as a therapy for familial hypercholesterolemia, but LDL-A has also been used as a general treatment for drug-resistant nephrotic syndrome (NS) due to focal segmental glomerulosclerosis (FSGS). The patients with NS due to minimal change disease (MCD) are often difficult to control effective circulating plasma volume, causes acute kidney injury (AKI), and when diuretics are not effective and the respiratory condition of patients worsens, patients require acute renal replacement therapy (ARRT). The effectiveness of LDL-A is not only reduction of serum low-density lipoprotein but also various other benefits. LDL-A might have improved renal hemodynamics by reducing vasoconstrictive eicosanoids and contributed to the therapeutic effect of antiproteinuric drugs such as corticosteroids. We treated a 49-year-old Japanese woman and a 71-year-old Japanese man with AKI caused by NS due to MCD, who required ARRT. Although these patients received ARRT and corticosteroids, their AKI and MCD did not improve sufficiently. We initiated LDL-A treatment for these patients as an additional treatment modality, because their total serum cholesterol levels were high at the time of admission. After the additional LDL-A treatment, both patients were able to discontinue ARRT, because NS and AKI in both patients were improved sufficiently. It is possible that early additional LDL-A is effective for patients with AKI and NS due to MCD who require ARRT, and may help patients discontinue ARRT because of the effect of LDL-A such as improving hypercoagulability and renal hemodynamics and contributing to the therapeutic effect of corticosteroids.
