Objective To evaluate the adequacy of dialysis in patients on nighttime intermittent peritoneal dialysis (NIPD). Design Retrospective review of prospectively collected data. Patients Seven patients on NIPD. Measurements The fast peritoneal equilibration test (PET) was used to determine peritoneal membrane permeability for small solutes. Adequacy of dialysis measured by 24hour collections of dialysate and urine for weekly KT/V and creatinine clearance in liters/week/1.73 m2 was assessed in patients with (n=3) and without (n=4) residual renal function and evaluated in concert with the patient's clinical status. Outcome for each patient was also noted. Results Five of the patients had a high-average dialysate/serum creatinine by PET (>0.66). Despite a weekly KT/V of 1.7 or more, four of the seven patients on NIPD were uremic and either transferred to hemodialysis or continuous cycling peritoneal dialysis (CCPD). A fifth patient had a KT/V of 1.4 and was also uremic on NIPD. The patient who was clinically well and continued on NIPD had significant residual renal function. Conclusions NIPD should be restricted to patients with high-average dialysate/serum creatinine as determined by PET and residual renal function or those with high dialysate/serum creatinine. Extended dialysis time and large volumes of dialysate are required for successful NIPD in patients without residual renal function. Accepted parameters of dialysis adequacy used for patients on continuous peritoneal dialysis are not appropriate for intermittent forms of peritoneal dialysis.

Glycocalyx is present on the surface of healthy endothelium, and the concentration of serum syndecan-1 can serve as an injury marker. This study aimed to assess endothelial injury using serum syndecan-1 as a marker of endothelial glycocalyx injury in patients who underwent hemodialysis. In this single-center, retrospective, observational study, 145 patients who underwent hemodialysis at the Gifu University Hospital between March 2017 and December 2019 were enrolled. The median dialysis period and time were 63 months and 3.7 h, respectively. The serum syndecan-1 concentration significantly increased from 124.6 ± 107.8 ng/ml before hemodialysis to 229.0 ± 138.1 ng/ml after hemodialysis (P < 0.001). Treatment with anticoagulant nafamostat mesylate inhibited hemodialysis-induced increase in the levels of serum syndecan-1 in comparison to unfractionated heparin. Dialysis time and the change in the syndecan-1 concentration were positively correlated. Conversely, the amount of body fluid removed and the changes in the syndecan-1 concentration were not significantly correlated. The reduction in the amount of body fluid removed and dialysis time inhibited the change in the syndecan-1 levels before and after hemodialysis. In conclusion, quantitative assessment of the endothelial glycocalyx injury during hemodialysis can be performed by measuring the serum syndecan-1 concentration, which may aid in the selection of appropriate anticoagulants, reduction of hemodialysis time, and the amount of body fluid removed.

Abstract Background and Aims Patients with end-stage kidney disease on dialysis are susceptible to severe COVID-19 infections. However, during the pandemic, many renal patients were unable to ‘shield’ fully due to the ongoing need to attend the dialysis unit for treatment. With a significant proportion of our haemodialysis population coming from socially deprived and ethnic minority background (38%), we aimed to explore patients’ understanding and experience of COVID-19 pandemic. Method This was a cross-sectional survey of patients receiving in-centre haemodialysis from one centre in England conducted during July 2020, three months after the first UK national lockdown. The questionnaire consisted of 18 questions exploring patients’ awareness of COVID-19 pandemic, understanding of ‘shielding’, use of face covering, and their experience of haemodialysis treatment as well as accessing healthcare during COVID-19 pandemic. Those with language barriers were offered assistance and verbal translation by haemodialysis nurses, if possible, to complete the questionnaire. Results In total, 232 patients (of a total of 479 in-centre dialysis patients, 48% response rate) completed and returned the questionnaire. Of these, 29 (12.5%) patients required help with the questionnaire due to language barrier. Mean age was 62 (SD 16) years, 63% were male, 53% were from ethnic minorities and 45% were from the most deprived area (MDI Decile 1). A third of the respondents lived with 3 or more adults at home and a quarter lived with one or more child. Majority of the patients (97%) were aware of COVID-19 pandemic, and most received information on COVID-19 from the news (87%). Dialysis staff (43.1%), family and friends (32.6%), internet (31%) and general practitioners (20.3%) were also key sources of information. Despite this, 17.2% of the patients did not know about ‘shielding’. Even though 3 in 4 patients stated that they were ‘always’ or ‘often’ able to ‘shield’, when prompted with scenarios, significant number of patients in fact felt that they were unable to shield when travelling to dialysis (56%), during dialysis (35%) or when shopping (17%). Majority of the patients (89%) said that they wore face covering and 28% self-isolated from the rest of household during the first peak of pandemic. 83% practised ‘social distancing’ at dialysis units but 5% did not and 6% felt unable to do so. Almost a quarter of the patients (23%, 54 patients) felt unwell during the first wave of COVID-19. Majority (50%) of them sought medical help by informing the dialysis unit, whilst 26% contacted their GP and 38% attended emergency departments. Of these 54 patients, 35% had difficulties accessing medical help, especially from primary care. One in four patients felt that their dialysis experience had changed during the pandemic: 10% increased use of private taxis or used different travel services, 3.5% reported increased travel time, 8% dialysed at a different unit, 5% experienced longer waiting time to start dialysis sessions and 4% had dialysis frequency reduced . Almost a third (29%) of the patients knew of someone in the dialysis unit who had COVID-19 infection during the first wave of pandemic. Conclusion COVID-19 posed significant challenges for patients receiving in-centre haemodialysis. Despite their high susceptibility to severe COVID infection, significant number of patients was not aware of ‘shielding’ or able to ‘shield’ effectively. Some also experienced difficulties accessing medical help and a quarter reported change of transport or dialysis arrangement during the pandemic.

Background: Clinical practice guidelines recommend arteriovenous fistulas as the preferred form of vascular access for hemodialysis. However, some studies have suggested that older age is associated with poorer fistula outcomes. Objective: We assessed the impact of age on the outcomes of fistula creation and access-related procedures. Design: This was a prospective cohort study using data collected as part of the Dialysis Measurement Analysis and Reporting (DMAR) system. Setting: Participating Canadian dialysis programs, including Southern Alberta Renal Program, Manitoba Renal Program, Sunnybrook Health Sciences Centre (Toronto, Ontario), London Health Sciences Centre (London, Ontario), and The Ottawa Hospital (Ottawa, Ontario). Patients: Incident hemodialysis patients aged 18 years and older who started dialysis between January 1, 2004, and May 31, 2012. Measurements: The primary outcome was the proportion of all first fistula attempts that resulted in catheter-free fistula use, defined as independent use of a fistula for hemodialysis (ie, no catheter in place). Secondary outcomes included the time to catheter-free fistula use among patients with a fistula creation attempt, total number of days of catheter-free fistula use, and the proportion of a patient’s hemodialysis career spent with an independently functioning fistula (ie, catheter-free fistula use). Methods: We compared patient characteristics by age group, using t tests or Wilcoxon rank sum tests, and chi-square or Fisher exact tests, as appropriate. Logistic and fractional logistic regression were used to estimate the odds of achieving catheter-free fistula use by age group and the proportion of dialysis time spent catheter-free, respectively. Results: A total of 1091 patients met our inclusion criteria (567 age ≥ 65; 524 age < 65). Only 57% of first fistula attempts resulted in catheter-free fistula use irrespective of age (adjusted odds ratio [OR]≥65vs<65: 1.01; P = .93). The median time from hemodialysis start to catheter-free use of the first fistula did not differ by age when grouped into fistulas attempted pre- and post-dialysis initiation. The adjusted rates of access-related procedures were comparable (incidence rate ratio [IRR]≥65vs<65: 0.95; P = .32). The median percentage of follow-up time spent catheter-free was similar and low in patients who attempted fistulas (<65 years: 19% vs ≥65 years: 21%; P = .85). Limitations: The relatively short follow-up time may have underestimated the benefits of fistula creation and the observational study design precludes inferences about causality. Conclusions: In our study, older patients who underwent a fistula attempt were just as likely as younger patients to achieve catheter-free fistula use, within a similar time frame, and while requiring a similar number of access procedures. However, the minority of dialysis time was spent catheter-free.
