ABSTRACTBackgroundThe COVID-19 pandemic of 2020 poses a particularly high risk for End Stage Renal Disease (ESRD) patients and led to a need for facility-wide control plans to prevent introduction and spread of infection within ESRD facilities. Rapid identification of clusters of contemporaneous cases is essential, as these may be indicative of within-facility spread. Nevertheless, in a setting of high community COVID-19 prevalence, a series of ESRD patients may test positive at around the same time without their shared ESRD facility being the nexus for disease spread. Here we describe a series of five cases occurring within an eleven-day period in November 2020 in a hospital-based 32-station ESRD facility in southwest Wisconsin, the subsequent facility-wide testing, and the use of genetic sequence analysis of positive specimens to evaluate whether these cases were linked.MethodsFour patient cases and one staff case were identified in symptomatic individuals by RT-PCR. Facility-wide screening was initiated at the request of local public health and conducted using Abbot BinaxNOW antigen tests. SARS-CoV-2 genome sequences were obtained from residual diagnostic test specimens using an amplicon-based approach on an Ion Torrent S5 sequencer.ResultsResidual specimens from 4 of 5 cases were available for sequence analysis. Each sequence was very clearly genetically distinct from the others, indicating that these contemporaneous cases were not linked. Facility-wide screening of 47 staff and 107 patients did not identify any additional cases.ConclusionsThese data indicate that despite the outward appearance of a case cluster, the facility did not experience within-facility spread nor serve as the epicenter of a new outbreak, suggesting that the enacted rigorous infection control procedures (screening, masking, distancing) practiced stringently by patients and staff were sufficient to permit dialysis to proceed safely in a very high-risk population under pressure from increasing community spread. These data also demonstrate the utility of rapid turnaround SARS-CoV-2 sequencing in outbreak investigations in settings like ESRD facilities.

Cachexia is common in end-stage renal disease (ESRD) patients, and it is an important risk factor for poor quality of life and increased mortality and morbidity. Chronic inflammation is an important cause of cachexia in ESRD patients. In the present review, we examine recent evidence suggesting that adipokines or adipocytokines such as leptin, adiponectin, resistin, tumor necrosis factor α, interleukin-6, and interleukin-1β may play important roles in uremic cachexia. We also review the physiology and the potential roles of gut hormones, including ghrelin, peptide YY, and cholecystokinin in ESRD. Understanding the molecular pathophysiology of these novel hormones in ESRD may lead to novel therapeutic strategies.

Hemodialysis is the most common type of treatment for end-stage renal disease (ESRD). Frailty is associated with poor outcomes such as higher mortality. ESRD patients have a higher prevalence of frailty. This systematic review and meta-analysis aimed to identify the prevalence and associated factors of frailty and examine whether it is a predictor of mortality among ESRD patients undergoing hemodialysis. Five electronic databases including PubMed, Embase, CINAHL, Web of Science, and Cochrane Library were searched for relevant studies up to 30 November 2020. A total of 752 articles were found, and seven studies with 2604 participants in total were included in the final analysis. The pooled prevalence of frailty in patients with ESRD undergoing hemodialysis was 46% (95% Confidence interval (CI) 34.2−58.3%). Advanced age, female sex, and the presence of diabetes mellitus increased the risk of frailty in ESRD patients undergoing hemodialysis. Our main finding showed that patients with frailty had a greater risk of all-cause mortality compared with those without (hazard ratio (HR): 2.02, 95% CI: 1.65−2.48). To improve ESRD patient outcomes, healthcare professionals need to assess the frailty of older ESRD patients, particularly by considering gender and comorbidities. Comprehensive frailty screening tools for ESRD patients on hemodialysis need to be developed.

Fibrin Clots

SummaryFibrin clots with reduced permeability, increased clot stiffness and reduced fibrinolysis susceptibility may predispose to cardiovascular disease (CVD). Little is known, however, about the structure of fibrin clots in patients with end-stage renal disease (ESRD).These patients suffer from a high risk of CVD in addition to their chronic low-grade inflammation. Using permeability, compaction and turbidity studies in 22 ESRD patients and 24 healthy controls, fibrin clots made from patient plasma were found to be less permeable (p<0.001), less compactable (p<0.001), and less susceptible to fibrinolysis (p<0.001) than clots from controls.The maximum rate of turbidity increase was also higher for the patients than controls (p<0.001), and scan-ning electron microscopy revealed higher clot density of fibrin fibers in clots from patients than clots from controls (p<0.001). Patients had higher plasma concentrations of fibrinogen, C-reative protein and interleukin 6 than controls.These plasma markers of inflammation correlated significantly with most of the fibrin structure characteristics observed in the patients. In contrast, plasma markers of azothemia showed no such correlations. The results suggest that in ESRD patients fibrin clots are significantly different from healthy controls, and that the fibrin structure characteristics in the patients are associated primarily with the inflammatory plasma milieu rather than with level of azothemia.

ABSTRACTAlbinterferon alfa-2b (albIFN) is being developed, in combination with ribavirin, for the treatment of hepatitis C virus infection. This study was designed to evaluate the pharmacokinetics, safety, and tolerability of a 900-μg dose of albIFN administered as a single subcutaneous injection in end-stage renal disease (ESRD) patients on hemodialysis and matched healthy volunteers (by age [±5 years], weight [±5 kg], and gender). The maximum concentration in plasma (Cmax) and the area under the concentration-time curve from time zero to infinity (AUC0-∞) were 42.8 ± 14.0 ng/ml and 16,414 ± 4,203 ng·h/ml, respectively, for healthy volunteers, while theCmaxand AUC0-∞were 49.9 ± 20.9 ng/ml and 18,919 ± 8,008 ng·h/ml, respectively, for ESRD patients. The geometric least-squares mean ratios were 1.15 (90% confidence interval [CI], 0.78, 1.68) forCmaxand 1.11 (90% CI, 0.83, 1.48) for AUC0-∞. Adverse events were as expected for an interferon (e.g., flu-like symptoms), with the main laboratory adverse event being a decline in total white blood cell count, which was specifically related to a decline in the neutrophil count. This effect was somewhat greater in the ESRD patients, with the maximal decreases in neutrophil counts from those at the baseline being (−2.6 ± 0.32) × 109and (−2.19 ± 0.58) × 109cells/liter for the ESRD patients and the healthy volunteers, respectively. This study indicates no significant effect of renal failure on the pharmacokinetics of albIFN. Safety and tolerability were as expected for an interferon.

End-stage renal disease (ESRD) is becoming more prevalent in Australia. As a result, strategies to improve quality of life when living with ESRD are becoming increasingly important. The Flinders Program has been developed to help support and increase the self-management capacity of people living with chronic disease. The Partners in Health (PIH) scale is a self-management capacity assessment tool, which is an integral element of the Flinders Program. The primary aim of this study was to investigate the preliminary measurement properties of the PIH scale within the ESRD population. Forty participants took part in the study, which involved survey assessments at baseline and follow up and a semi-structured interview. Results indicated that the PIH scale had good internal reliability (α=0.85), moderate test-retest reliability (r=0.33) and face validity in ESRD patients. Areas for improving the instrument or data collection process were identified through qualitative interviews, and implications are discussed specific to ESRD patients.
