IntroductionCardiovascular disease is a leading cause of death in patients with end-stage kidney disease (ESKD). However, ascertaining the impact of cardiovascular deaths has not been well characterised over long periods of follow-up and across different treatment states. Further insights into the lifetime risk of cardiovascular death are required to better inform clinical practice and economic planning. Objectives and ApproachWe performed a population-based cohort study on incident patients receiving ESKD treatment from the Australian and New Zealand Dialysis and Transplant registry (ANZDATA). Cardiac/vascular deaths were determined from ICD-10-AM codes listed in the underlying cause of death obtained via data linkage with the Australian National Death Index and New Zealand Mortality Collection database. We estimated mortality rates from cardiac/vascular death across time from ESKD treatment, and calculated probability of death and transplant status over time using multistate models. ResultsAcross 60,823 incident ESKD patients and 381,874 person-years of follow-up, 22% (7,551) of deaths were from cardiac/vascular disease. At 15 years from treatment, 15.6% of patients had died from cardiac/vascular causes, most of whom never received a transplant (13.6% vs 2.0% of cohort). Within the first year of dialysis, cardiac/vascular mortality was highest in the second month, at 3,632/100,000pys. Improvements in cardiac/vascular mortality with calendar year were only seen after 9 months of dialysis. Transplant recipients had consistently lower cardiac/vascular mortality rates (598/100,000 pys) compared to dialysis patients. However, comorbid cardiovascular disease was a risk factor for graft failure and death in transplant recipients (HR:1.52, 95% CI:1.42-1.62). Conclusion / ImplicationsDespite improvements in cardiac/vascular outcomes over time, cardiovascular death remains common in ESKD, particularly in the first few months of treatment. A greater focus on secondary prevention in earlier stages of chronic kidney disease may improve outcomes in new ESKD patients.

Renal functional deterioration is associated with physical and mental burdens for kidney transplant (KT) and chronic kidney disease (CKD) patients. However, the change in health-related quality of life (HRQOL) over time in KT patients compared to that of native CKD patients has not been evaluated. We addressed this issue using KT patients registered in the KNOW-KT cohort study and patients at CKD stage 1–3 registered in the KNOW-CKD cohort study. HRQOL scores were assessed using the Kidney Disease Quality of Life Short Form at baseline, 2-, and 4-years follow-up in 842 KT patients and at baseline and 5-year follow-up in 1,355 CKD patients. SF-36 scores declined at the 4-year follow-up, whereas CKD-targeted scores showed no change in the KT group. In contrast, CKD-targeted scores as well as SF-36 scores were decreased at the 5-year follow-up in CKD patients. When prognostic factors were analyzed for longitudinal HRQOL data over time, renal functions, diabetes, cardiovascular and cerebrovascular diseases, hemoglobin level, marital status, income, employment, and health care were significant prognostic factors. Furthermore, KT was an independent prognostic factor for better HRQOL. These results highlight that KT can offer a better HRQOL than that of CKD patients, even when renal function is similar.

Introduction: Premature mortality (deaths before age 75) is a well-established metric of population health and health system performance. In Canada, underlying differences between provinces/territories present a need for stratified mortality trends. Methods: Using data from the Canadian Vital Statistics Database, a descriptive analysis of sex-specific adult premature deaths over 1992-2015 was conducted by province, census divisions (CD), socioeconomic status (SES), age, and underlying cause of death. Premature mortality rates were calculated as the number of deaths per 100,000 individuals aged 18 to 74, per 8-year era. SES was measured using the income quintile of the neighbourhood of residence. Absolute and relative inequalities were respectively summarized using slope and relative indices of inequality, produced via unadjusted linear regression of the mortality rate on income rank. Results: Premature mortality in Canada declined by 21% for males and 13% for females between 1992-1999 and 2008-2015. The greatest reductions were in Central Canada, while Newfoundland saw notable increases. CD-level improvements appeared mostly in the southern half of Canada. As of 2008-2015, Newfoundland, Nova Scotia, and Nunavut had the highest mortality rates. Low area-level income was associated with higher mortality. SES inequalities grew over time. Newfoundland’s between-quintile differences rose from 1292 to 2389 deaths per 100k males, or 1.33 to 2.12-fold, and 586 to 1586 per 100k females, or 1.24 to 1.74-fold. In 2008-2015, mortality rates of the bottom quintile in Manitoba and Saskatchewan were more than 2.5 times those of the top. Mortality increased with age, and varied regionally. Low mortality in Central Canada and BC, and high mortality in the Territories were consistent across eras and sexes. Cause of death distributions shifted with age and sex, with more external deaths in younger males. Conclusion: Improvements were seen in adult premature mortality rates over time, but were unequal across geographies. Evidence exists for growing socioeconomic disparities in mortality.

Abstract Acute kidney injury (AKI) has an incidence rate of 5-6% among intensive care unit (ICU) patients and sepsis is the most frequent etiology. Aims: To assess patients in the ICU that developed AKI, AKI on chronic kidney disease (CKD), and/or sepsis, and identify the risk factors and outcomes of these diseases. Methods: A prospective observational cohort quantitative study that included patients who stayed in the ICU > 48 hours and had not been on dialysis previously was carried out. Results: 302 patients were included and divided into: no sepsis and no AKI (nsnAKI), sepsis alone (S), septic AKI (sAKI), non-septic AKI (nsAKI), septic AKI on CKD (sAKI/CKD), and non-septic AKI on CKD (nsAKI/CKD). It was observed that 94% of the patients developed some degree of AKI. Kidney Disease Improving Global Outcomes (KDIGO) stage 3 was predominant in the septic groups (p = 0.018). Nephrologist follow-up in the non-septic patients was only 23% vs. 54% in the septic groups (p < 0.001). Dialysis was performed in 8% of the non-septic and 37% of the septic groups (p < 0.001). Mechanical ventilation (MV) requirement was higher in the septic groups (p < 0.001). Mortality was 38 and 39% in the sAKI and sAKI/CKD groups vs 16% and 0% in the nsAKI and nsAKI/CKD groups, respectively (p < 0.001). Conclusions: Patients with sAKI and sAKI/CKD had worse prognosis than those with nsAKI and nsAKI/CKD. The nephrologist was not contacted in a large number of AKI cases, except for KDIGO stage 3, which directly influenced mortality rates. The urine output was considerably impaired, ICU stay was longer, use of MV and mortality were higher when kidney injury was combined with sepsis.

<b><i>Background and Aims:</i></b> Abdominal aortic calcification (AAC) is common in chronic kidney disease (CKD) patients and associated with increased mortality. Comparative data on the AAC score progression in CKD patients transitioning from conservative treatment to different modalities of renal replacement therapy (RRT) are lacking and were examined. <b><i>Methods:</i></b> 150 study patients underwent lateral lumbar radiograph to study AAC in the beginning of the study before commencing RRT (AAC1) and at 3 years of follow-up (AAC2). We examined the associations between repeated laboratory tests taken every 3 months, echocardiographic and clinical variables and AAC increment per year (ΔAAC), and the association between ΔAAC and outcomes during follow-up. <b><i>Results:</i></b> At the time of AAC2 measurement, 39 patients were on hemodialysis, 39 on peritoneal dialysis, 39 had a transplant, and 33 were on conservative treatment. Median AAC1 was 4.8 (0.5–9.0) and median AAC2 8.0 (1.5–12.0) (<i>p</i> &#x3c; 0.0001). ΔAAC was similar across the treatment groups (<i>p</i> = 0.19). ΔAAC was independently associated with mean left ventricular mass index (LVMI) (log LVMI: β = 0.97, <i>p</i> = 0.02) and mean phosphorus through follow-up (log phosphorus: β = 1.19, <i>p</i> = 0.02) in the multivariable model. Time to transplantation was associated with ΔAAC in transplant recipients (per month on the waiting list: β = 0.04, <i>p</i> = 0.001). ΔAAC was associated with mortality (HR 1.427, 95% confidence interval 1.044–1.950, <i>p</i> = 0.03). <b><i>Conclusion:</i></b> AAC progresses rapidly in patients with CKD, and ΔAAC is similar across the CKD treatment groups including transplant recipients. The increment rate is associated with mortality and in transplant recipients with the time on the transplant waiting list.

Stroke Death

IntroductionPeople with end-stage kidney disease (ESKD) have up to 30-fold higher risk of stroke than the general population.ObjectiveTo determine risk factors associated with stroke death in the ESKD population.MethodsWe identified all patients with incident ESKD in Australia (1980–2013) and New Zealand (1988–2012) from the Australian and New Zealand Dialysis and Transplant Registry (ANZDATA) registry. We ascertained underlying cause of death from data linkage with national death registries and risk factors from ANZDATA. Using a competing risks multivariable regression model, we estimated cumulative incidence of stroke and non-stroke deaths, and risk factors for stroke deaths (adjusted sub-HR, SHR).ResultsWe included 60 823 people with ESKD. There were 941 stroke deaths and 33 377 non-stroke deaths during 381 874 person-years of follow-up. Overall, the cumulative incidence of stroke death was 0.9% and non-stroke death was 36.8% 5 years after starting ESKD treatment. The risk of stroke death was higher at older ages (SHR 1.92, 95% CI 1.45 to 2.55), in females (SHR 1.41, 95% CI 1.21 to 1.64), in people with cerebrovascular disease (SHR 2.39, 95% CI 1.99 to 2.87), with ESKD caused by hypertensive/renovascular disease (SHR 1.39, 95% CI 1.09 to 1.78) or polycystic kidney disease (SHR 1.38, 95% CI 1.00 to 1.90), with earlier year of ESKD treatment initiation (SHR 1.93, 95% CI 1.56 to 2.39) and receiving dialysis (transplant vs haemodialysis SHR 0.27, 95% CI 0.09 to 0.84).ConclusionPatients with ESKD with higher risk of stroke death are older, women, with cerebrovascular disease, with hypertensive/renovascular or polycystic kidney disease cause of ESKD, with earlier year of ESKD treatment and receiving dialysis. These groups may benefit from targeted stroke prevention interventions.

Abstract Background and Aims Cardiovascular mortality is high in chronic kidney disease (CKD) patients. Recognizing patients with higher cardiovascular risk might help in their treatment. CHA2DS2-VASc score was originally used to predict cerebral infarction in patients with atrial fibrillation (AF). However, it is also useful in predicting outcome in different cardiovascular conditions, independent of the presence of AF. Therefore, the aim of our research was to assess the role of CHA2DS2-VASc score in cardiovascular mortality in CKD patients. Method Eighty-seven non-dialysis CKD patients from our outpatient clinic were included. At the time of inclusion, medical history data and standard blood results were collected and CHA2DS2-VASc score was calculated. Patients were followed for assigned time or until their death. Mean follow-up time was 1696.45±564.60 days. Results Descriptive statistics of our patients are presented in table 1. During follow-up 11 patients suffered from cardiovascular death. Univariate Cox regression analysis showed that CHA2DS2-VASc score is a significant predictor of cardiovascular mortality (HR: 2.19, CI: 1.42-3.37, p=0.001). In multivariate Cox regression analysis in which CHA2DS2-VASc score, serum creatinine, urinary albumin/creatinine, haemoglobin, high sensitivity CRP and intact PTH were included, CHA2DS2-VASc score was an independent predictor of cardiovascular mortality (HR: 2.04, CI: 1.20-3.45, p=0.008) (table 2). Conclusion CHA2DS2-VASc score is a simple and quick way to identify cardiovascular risk in CKD patients.

High mortality rates among schizophrenic patients from infectious diseases, particularly tuberculosis, pneumonia and gastro-enteritis, reported for periods up to the 1940s were shown not to be specific for schizophrenia, but were characteristic of the mental hospital population as a whole (Alstrom, 1942). Studies covering more recent times confirm the decline and virtual disappearance of mortality from tuberculosis (Baldwin, 1979), but an extensive literature continues to emphasise the relatively high mortality of the mentally ill, including those defined as schizophrenic (Innes & Millar, 1970; Tsuang & Woolson, 1977), and more recent record linkage studies (Herrman et al, 1983; Allebeck & Wistedt, 1986) have continued to show an excess of both natural and unnatural deaths. Long follow-up studies of reasonably large groups of well documented cases are relatively uncommon in this area and therefore the 532 cases in the Harrow study were carefully followed up from the point of view of the occurrence and cause of death.

The acute phase protein group IIA secretory phospholipase A2 (sPLA2-IIA) has proatherosclerotic properties. The present study prospectively investigated whether plasma sPLA2-IIA levels are associated with graft failure, cardiovascular and all-cause mortality in renal transplant recipients (RTRs), patients known to be susceptible to accelerated atherosclerosis, both in the graft and in the systemic vasculature. In 495 RTRs (median follow-up 7.0 years) sPLA2-IIA was determined at baseline and was significantly higher in RTRs than in healthy controls (median 384 ng/dL [range 86-6951] vs. 185 ng/dL [range 104-271], P<0.001), but lower than in end-stage renal disease patients (median 1053 ng/mL [range 458-2599], P<0.001). Kaplan-Meier analysis demonstrated an increased risk for graft failure (P=0.002), cardiovascular (P<0.001) and all-cause mortality (P<0.001) with increasing gender-stratified quartiles of sPLA2-IIA. Cox regression analyses showed a strong association of sPLA2-IIA with increased risks of graft failure (hazard ratio=1.42[1.11-1.83], P=0.006), cardiovascular (hazard ratio=1.48[1.18-1.85], P=0.001) and all-cause mortality (hazard ratio=1.39[1.17-1.64], P<0.001). However, this association was largely explained by parameters of kidney function. Further analyses in RTRs demonstrated that patients with higher baseline sPLA2-IIA levels showed faster decline in renal function during follow-up. In addition, kidney function in human sPLA2-IIA transgenic mice deteriorated more rapid over time as compared with wild-type controls (urinary albumin:creatinine ratio at 48 weeks of age 774±156 vs. 193±60, P<0.01). In summary, this prospective study demonstrates that sPLA2-IIA is a significant predictive biomarker for the occurrence of chronic graft failure, overall and CVD mortality in RTRs dependent on kidney function. This dependency is explained by sPLA2-IIA impacting negatively on kidney function over time in humans and transgenic mice.
