Background: It is unclear how traditional cardiovascular risk factors and different treatment modalities for end-stage kidney disease (ESKD) affect stroke risk in people with ESKD. We aimed to identify the risk factors for stroke (ischemic and hemorrhagic) in people with ESKD. Methods: We conducted a retrospective cohort study using data linkage between the Australian and New Zealand Dialysis and Transplant Registry, clinical and administrative datasets. Using Cox proportional hazards models, we estimated the magnitudes of risk of hospitalization with different subtypes of strokes associated with traditional cardiovascular risk factors and ESKD treatment modalities (hemodialysis (HD), peritoneal dialysis (PD) and kidney transplantation). Results were expressed as hazard ratios (HRs) with 95% CIs. Results: A total of 10,745 people received treatment for ESKD in New South Wales, Australia, between 2000 and 2010. We observed 640 hospitalizations for stroke in 49,497 person-years of follow-up (129.4 per 10,000 person years). Some risk factors were consistent with those found in the general population, including smoking and a history of previous stroke. Other risk factors were novel for people with ESKD. Women were 85% more likely to have an intracerebral hemorrhage (HR 1.85, 95% CI 1.22-2.79) and 30% more likely to have an ischemic stroke (HR 1.30, 95% CI 1.01-1.66) than men. Compared to people on HD, people with kidney transplants had a 65% lower risk of intracerebral hemorrhage (HR 0.35, 95% CI 0.18-0.69) but a similar risk of ischemic stroke (HR 0.97, 95% CI 0.64-1.49). People on PD had a 36% higher risk of ischemic stroke (HR 1.36, 95% CI 1.05-1.76) but a similar risk of intracerebral hemorrhage compared to people on HD (HR 0.69, 95% CI 0.43-1.11). Conclusions: These findings could be used to establish reliable estimates of the risk of stroke in people with ESKD and identify those who are most likely to benefit from preventive treatments.

Background: The newly introduced device Mobil-O-Graph (IEM, Stolberg, Germany) combines brachial cuff oscillometry and pulse wave analysis, enabling the determination of pulse wave velocity (PWV) via complex mathematic algorithms during 24-h ambulatory blood pressure monitoring (ABPM). However, the determinants of oscillometric PWV in the end-stage kidney disease (ESKD) population remain poorly understood. Methods: In this study, 81 ESKD patients undergoing long-term peritoneal dialysis underwent 24-h ABPM with the Mobil-O-Graph device. The association of 24-h oscillometric PWV with several demographic, clinical and haemodynamic parameters was explored using linear regression analysis. Results: In univariate analysis, among 21 risk factors, 24-h PWV exhibited a positive relationship with age, body mass index, overhydration assessed via bioimpedance spectroscopy, diabetic status, history of dyslipidaemia and coronary heart disease, and it had a negative relationship with female sex and 24-h heart rate. In stepwise multivariate analysis, age ( β: 0.883), 24-h systolic blood pressure (BP) ( β: 0.217) and 24-h heart rate ( β: −0.083) were the only three factors that remained as independent determinants of 24-h PWV (adjusted R 2 = 0.929). These associations were not modified when all 21 risk factors were analysed conjointly or when the model included only variables shown to be significant in univariate comparisons. Conclusion: The present study shows that age together with simultaneously assessed oscillometric BP and heart rate are the major determinants of Mobil-O-Graph-derived PWV, explaining >90% of the total variation of this marker. This age dependence of oscillometric PWV limits the validity of this marker to detect the premature vascular ageing, a unique characteristic of vascular remodelling in ESKD.

AbstractBackgroundPatients who require acute initiation of dialysis have higher mortality rates when compared with patients with planned starts. Our primary objective was to explore the reasons and risk factors for acute initiation of renal replacement therapy (RRT) among patients with end-stage kidney disease (ESKD). Our secondary objective was to determine the difference in glomerular filtration rate (GFR) change in the year preceding RRT between elective and acute dialysis starts.MethodsWe conducted a single-centre retrospective observational study. ESKD patients either started dialysis electively (planned starters) or acutely and were known to renal services for >90 (unplanned starters) or <90 days (urgent starters).ResultsIn all, 825 consecutive patients initiated dialysis between January 2013 and December 2015. Of these, 410 (49.7%) patients had a planned start. A total of 415 (50.3%) patients had an acute start on dialysis: 244 (58.8%) unplanned and 171 (41.2%) urgent. The reasons for acute dialysis initiation included acute illness (58%) and unexplained decline to ESKD (33%). Cardiovascular disease [n = 30 (22%)] and sepsis [n = 65 (48%)] accounted for the majority of acute systemic illness. Age and premorbid cardiovascular disease were independent risk factors for acute systemic illness among unplanned starts, whereas autoimmune disease accounted for the majority of urgent starts. The rate of decline in GFR was greater in the month preceding RRT among acute dialysis starters compared with planned starters (P < 0.001).ConclusionsCardiovascular disease and advancing age were independent risk factors for emergency dialysis initiation among patients known to renal services for >3 months. The rapid and often unpredictable loss of renal function in the context of acute systemic illness poses a challenge to averting emergency dialysis start.

Abstract Background Risk stratification in patients with type 2 diabetes continues to be an important priority in the management of diabetes-related morbidity and mortality. International guidelines generally recognize patients with diabetes and cardiovascular disease as high-risk patients. Risk stratification is, however, more uncertain in diabetes patients without cardiovascular disease. Micro- and macroalbuminuria have previously been identified as predictors of cardiovascular events and mortality in general cohorts of diabetes patients. However, less is known about the predictive value of albuminuria in patients with diabetes but without established cardiovascular disease. Purpose We aimed to examine the association between albuminuria level and the risk of ischemic stroke, myocardial infarction, and all-cause mortality in patients with type 2 diabetes and without a diagnosis of cardiovascular disease. Methods We linked Danish nationwide registries to identify patients with type 2 diabetes and without cardiovascular disease from May 2005 through June 2015. Based on two consecutive measurements of the urinary albumin excretion rate or albumin-to-creatinine ratio patients were stratified in categories of normoalbuminuria, microalbuminuria, and macroalbuminuria. Patients were followed for the outcomes ischemic stroke, myocardial infarction, and all-cause mortality until December 31, 2015. Five-year risk of outcomes were presented as cumulative incidence functions (with death as a competing event). Associations between albuminuria level and incidence of ischemic stroke, myocardial infarction, and all-cause mortality were evaluated with Cox proportional hazard regression adjusted for cardiovascular risk factors. Results The study population included 78,841 patients with type 2 diabetes (44.7% females, mean age 63.2). When comparing patients with microalbuminuria to patients with normoalbuminuria in an age- and sex-adjusted analysis, we found hazard ratios (HRs) of 1.45 (95% CI: 1.24–1.69), 1.45 (95% CI: 1.24–1.70), and 1.50 (95% CI: 1.39–1.61) for ischemic stroke, myocardial infarction, and all-cause mortality, respectively. Furthermore, macroalbuminuria was associated with HRs of 2.05 (95% CI: 1.70–2.48), 2.25 (95% CI: 1.86–2.71), and 2.03 (95% CI: 1.85–2.23) for ischemic stroke, myocardial infarction, and all-cause mortality, respectively. Similar results were found after adjusting for cardiovascular risk factors. Conclusions In this nationwide cohort study of patients with type 2 diabetes but without cardiovascular disease, patients with micro- and macroalbuminuria had a higher risk of incident ischemic stroke, myocardial infarction, and all-cause mortality. This finding supports that patients with micro- or macroalbuminuria should be screened regularly and followed closely in clinical practice. Moreover, these findings suggest that patients with type 2 diabetes and micro- or macroalbuminuria may benefit from intensive vascular risk reduction.

Background The rate of sudden cardiac death in the hemodialysis population exceeds that of the general population by >20‐fold. Hemodialysis patients may be particularly susceptible to sudden cardiac death provoked by drug‐induced QT prolongation because of their substantial cardiovascular disease burden, exposure to electrolyte shifts during dialysis, and extensive polypharmacy. However, population‐specific data regarding the frequency and patterns of QT prolonging medication use are limited. Methods and Results We conducted a descriptive drug utilization study using 3 administrative databases, the United States Renal Data System, MarketScan, and Medicare claims. We characterized the extent and patterns of QT prolonging medication use by adult hemodialysis patients and individuals without end‐stage kidney disease annually from 2012 to 2016. We also identified instances of high‐risk QT prolonging medication use among hemodialysis patients. In total, 338 515 hemodialysis patients and 40.7 million individuals without end‐stage kidney disease were studied. Annual utilization rates of QT prolonging medications with known torsades de pointes risk in hemodialysis patients were ~1.4 to ~2.5 times higher than utilization rates in individuals without end‐stage kidney disease. Hemodialysis patients with demographic and clinical risk factors for drug‐induced QT prolongation were exposed to medications with known torsades de pointes risk more often than patients without risk factors. Conclusions Hemodialysis patients use QT prolonging medications with known torsades de pointes risk more extensively than individuals without end‐stage kidney disease. Given the widespread use and instances of high‐risk prescribing, future studies evaluating the cardiac safety of these drugs in the hemodialysis population are needed.

Background: Meeting place-of-death preferences is an important measure of the quality of end-of-life care. Systematic review shows that 42% of end-stage kidney disease patients prefer home death. Little research has been undertaken on place of death. Aim: To understand patterns of place of death in patients with end-stage kidney disease known in one UK renal unit. Design: A retrospective cohort study of all patients with chronic kidney disease stage 4–5, age ⩾75 and known to one UK renal unit, who died between 2006 and 2012. Patients were categorised into three management pathways: haemodialysis, conservative and pre-dialysis. Results: A total of 321 patients (mean age, 82.7; standard deviation, 5.21) died (61.7% male). In all, 62.9% died in hospital (95% confidence interval, 57.5%–68.1%), 21.8% died in their usual place of residence (95% confidence interval, 17.5%–26.6%) and 15.3% died in an inpatient palliative care unit (95% confidence interval, 11.6%–19.5%). Management pathway and living circumstances were most strongly associated with place of death. Patients on the conservative pathway had four times the odds of dying out of hospital (odds ratio, 4.0; 95% confidence interval, 2.1–7.5; p < 0.01). Patients living alone were less likely to die out of hospital (odds ratio, 0.3; 95% confidence interval, 0.1–0.6; p < 0.01). There were also changes in place of death over time, with more patients dying out of hospital in 2012 compared to 2006 (odds ratio, 3.1; 95% confidence interval, 1.0–9.7; p < 0.05). Conclusion: Most patients with end-stage kidney disease die in hospital, but patients managed without dialysis are significantly more likely to die outside of hospital. Planning ahead is key to be able to meet preference for place of death.
