Abstract Background and Aims Chronic kidney disease-mineral and bone disorder (CKD-MBD) is frequent in end-stage renal disease (ESRD) patients, increasing morbid-mortality. The aim of this study was to determine the prevalence and phenotype of bone disease before transplantation; and to correlate FGF23, klotho and sclerostin serum levels with bone histomorphometric parameters and CV disease. The secondary aim was to correlate bone biopsies data with other bone related parameters, as PTH, bone alkaline phosphatase, 25-hidroxivitamin D3, calcitonin, calcium, phosphorus, and magnesium. Method We performed a prospective cohort study of a sample of ESRD patients listed for renal transplant. All patients were submitted to renal transplant and were followed for 12 months. Patient and graft survival were recorded. At inclusion, demographic and clinical data were collected, laboratorial evaluation; bone biopsy and X-ray of the pelvis and hands (Adragão score) were performed. Continuous variables are presented as medians and categorical variables as frequencies. Associations between variables were performed using Wilcoxon rank sum test, Fisher and Kruskal Wallis test. Multivariate analysis was performed using logistic regression. STATA software was used and p < 0.05 was considered statistically significant. Results We included 84 patients. Median age 53.5 (IQ range: 40.5 – 61.5) years, 59 men (70.2%), 65 caucasian (77.4%). The median left ventricular mass index was 108.5 (92 – 129) g/m2, with 32 patients presenting left ventricular hypertrophy and 19 valve calcifications. Median Adragão score was 1 (0 – 2). We diagnosed adynamic bone disease in 15 patients; hyperparathyroid bone disease in 19 patients; osteomalacia in 1 patient and mixed renal osteodystrophy in 3 patients. At the end of 12 months, 4 patients died, 5 had graft failure (non-primary function) and 4 had a cardiovascular event. Sclerostin was found to be a risk factor for low bone volume; whereas low phosphorus, low FGF23 and high bAP risk factors for abnormal mineralization. High turnover was mainly present in patients with high bAP and phosphorus and low sclerostin levels. The presence of valve calcifications was associated with low volume and with low or high turnover disorder. FGF23 appears as an important independent factor for vascular calcifications [as well age (p=0.009), BMI (p=0.02), presence of diabetes (p=0.01)], and for cardiovascular events. Sclerostin emerged as a risk factor for vascular calcifications and lower levels of sclerostin were associated with patient survival at the end of 12 months. Conclusion From the bone-derived hormones, sclerostin and FGF23 seem to act as risk factors for vascular calcifications and worse outcomes.

Abstract Background and Aims Chronic kidney disease-mineral and bone disorder (CKD-MBD) is frequent in end-stage renal disease ESRD (ESRD) patients, increasing morbid-mortality. The aim of this study was to analyse the associations between the new CKD-MBD players [alpha-klotho, fibroblast grow factor (FGF) 23, sclerostin] and the usual markers of the disease [parathyroid hormone (PTH), bone alkaline phosphatase (bAP), vitamin D (vitD), phosphorus (Pi), Calcium (Ca) and Magnesium (Mg)], as well echocardiographic findings [left ventricular mass index (LVMI) measured by Devereux formula, valvular calcifications], vascular calcifications and patients outcomes. Method We performed a prospective cohort study of a sample of ESRD patients listed for renal transplant. All patients were submitted to renal transplant and were followed for 12 months. Patient and graft survival were recorded. At inclusion, demographic and clinical data were collected, laboratorial evaluation, bone biopsy and X-ray of the pelvis and hands (Adragão score) were performed. Continuous variables are presented as medians and categorical variables as frequencies. Associations between variables were performed using Wilcoxon rank sum test and Spearman correlation test. STATA software was used and p < 0.05 was considered statistically significant. Results We included 85 patients. Mean age 50.1±12.7 years, 59 men (69.4%), 66 caucasian (77.6%). The median LVMI was 108.5 (92 – 129) g/m2, with 32 patients presenting LVH and 19 valvular calcifications. Median Adragão score was 1 (0 – 2). At the end of 12 months, 4 patients died and 5 had graft failure (non-primary function). Alpha-klotho correlated with bAP (p=0.0006) and marginally with PTH and absence of valvular calcifications (p=0.05). FGF23 correlated with Pi (p<0.001), Ca (p=0.004), PTH (p=0.003), Mg (p=0.002), and inversely with bAP (p=0.003). There was a marginal association with Adragão score (p=0.06). We didn’t found correlations between FGF23 and alpha-klotho or dialysis vintage or echocardiographic characteristics. Sclerostin correlated negatively with bAP (p=0.007) and PTH (p=0.04). The 3rd sclerostin tertile was associated with high scores of vascular calcifications (p=0.02). Lower levels of sclerostin were associated with patient survival at the end of 12 months (p=0.02). Conclusion From these 3 new bone-derived hormones, sclerostin, a bone formation inhibitor, seems to act as a risk factor for vascular calcifications and worse outcomes.

Abstract Introduction. End-stage renal disease (ESRD) patients undergoing hemodialysis are at an increased risk of arteriosclerotic vascular disease (ASVD). The increased risk is commonly attributed to the traditional risk factors related to ESRD. However, interest for more recent risk factors for ASVD, such as the level of lipoprotein(a) and its specific apoprotein(a) has been promoted. The aim of this paper is to determine whether apo(a) phenotype is a risk factor for arteriosclerotic vascular disease in ESRD patients who are on hemodialysis. Methods. Apo(a) phenotypisation was performed by using the Western Blot Technique of blood samples from 96 end-stage renal disease patients who were undergoing hemodialysis, and from 100 healthy individuals. Results. Frequency distribution of the basic apo(a) isoforms calculated by means of the χ2-test has shown that there was no significant statistical difference in distribution among patients on hemodialysis, and healthy carriers (χ2-0.36, p<0.548-for carriers of single apo(a) isoforms, (χ2-0.10, p<0.7545-for carriers of double apo(a) isoforms). The calculated relative risks have demonstrated that apo(a) phenotype was not a risk factor for ASVD in HD patients. Conclusion. Based on the results obtained, it can be concluded that the apo(a) phenotype is not a risk factor for arteriosclerotic vascular disease in patients undergoing hemodialysis.

Abstract Background Left ventricular dysfunction after an acute myocardial infarction (MI) is associated with poor outcome. The PARADISE-MI trial is examining whether an angiotensin receptor-neprilysin inhibitor reduces the risk of cardiovascular death or worsening heart failure (HF) in this population. The aim of this study was to examine the prevalence and prognosis of different subsets of post-MI patients in a real-world setting. Additionally, the prognostic importance of some common risk factors used as risk enrichment criteria in the PARADISE-MI trial were specifically examined. Methods In a nationwide myocardial infarction registry (SWEDEHEART), including 87 177 patients with type 1 MI between 2011–2018, 3 subsets of patients were identified in the overall MI cohort (where patients with previous HF were excluded); population 1 (n=27 568 (32%)) with signs of acute HF or an ejection fraction (EF) &lt;50%, population 2 (n=13 038 (15%)) with signs of acute HF or an EF &lt;40%, and population 3 (PARADISE-MI like) (n=11 175 (13%)) with signs of acute HF or an EF &lt;40% and at least one risk factor (Age ≥70, eGFR &lt;60, diabetes mellitus, prior MI, atrial fibrillation, EF &lt;30%, Killip III-IV and STEMI without reperfusion therapy). Results When all MIs, population 1 (HF or EF &lt;50%), 2 (HF or EF &lt;40%) and 3 (HF or EF &lt;40% + additional risk factor (PARADISE-MI like)) were compared, the median (IQR) age increased from 70 (61–79) to 77 (70–84). Also, the proportion of diabetes (22% to 33%), STEMI (38% to 50%), atrial fibrillation (10% to 24%) and Killip-class &gt;2 (1% to 7%) increased. After 3 years of follow-up, the cumulative probability of death or readmission because of heart failure in the overall MI population and in population 1 to 3 was 17.4%, 26.9%, 37.6% and 41.8%, respectively. In population 2, all risk factors were independently associated with death or readmission because of HF (Age ≥70 (HR (95% CI): 1.80 (1.66–1.95)), eGFR &lt;60 (1.62 (1.52–1.74)), diabetes mellitus (1.35 (1.26–1.44)), prior MI (1.16 (1.07–1.25)), atrial fibrillation (1.35 (1.26–1.45)), EF &lt;30% (1.69 (1.58–1.81)), Killip III-IV (1.34 (1.19–1.51)) and STEMI without reperfusion therapy (1.34 (1.21–1.48))) in a multivariable Cox regression analysis. The risk increased with increasing number of risk factors (Figure 1). Conclusion Depending on definition, post MI HF is present in 13–32% of all MI patients and is associated with a high risk of subsequent death or readmission because of HF. The risk increases significantly with every additional risk factor. There is a need to optimize management and improve outcomes for this high risk population.

<b><i>Aim:</i></b> To derive an echocardiography-based prognostic score for a 3-year risk of mortality in end-stage renal disease (ESRD) patients undergoing hemodialysis (HD). <b><i>Methods:</i></b> 173 ESRD patients hospitalized in the second affiliated hospital of Soochow University from January 1, 2010, to July 31, 2016, were enrolled and followed up for 3 years. All subjects began to receive HD from recruitment. Baseline clinical and echocardiographic parameters were collected and screened for risk factors using univariate and multivariate analysis. The prognostic value of echocardiographic indexes was determined by concordance indexes and reclassification assay. Restricted cubic spline models (RCS) and forest plots were employed to visualize the association between risk factors and all-cause mortality. A multivariate nomogram including the identified factors was developed to estimate the prognosis. <b><i>Results:</i></b> After multivariate adjustment for advanced age, hypertension, diabetes, and decreased hemoglobin (Hb), echocardiographic indexes including left atrial diameter index (LADI), cardiac valvular calcification, and moderate to severe cardiac valve regurgitation were independently associated with the risk of 3-year mortality in HD patients. RCS showed that age, Hb, and LADI were positively associated with the risk of mortality. Adding multiple echocardiographic indexes to a basic model containing age, hypertension, diabetes, and Hb increased the concordance index and improved reclassification. A multivariate Cox model-derived nomogram showed the association between each factor and mortality by the end of follow-up. <b><i>Conclusions:</i></b> Echocardiographic indexes showed independent predictive power for mortality in ESRD patients and may constitute a promising prognostic tool in this population.

Cardiovascular mortality in the end-stage renal disease (ESRD) population remains the leading cause of death. Targeting traditional cardiovascular risk factors has proven unsuccessful in this patient population, and therefore attention has turned to risk factors related to chronic kidney disease (CKD). The toxicity of high-glucose peritoneal dialysis (PD) solutions has been well documented. The breakdown of glucose into glucose degradation products (GDP) and advanced glycation end-products (AGE) has the ability to alter cell viability and cause premature apoptosis and is strongly correlated with interstitial fibrosis and microvascular sclerosis. Biocompatible solutions have been introduced to combat the hostile milieu to which PD patients are exposed.Given the considerable cardiovascular burden for PD patients, little is known about the cardiovascular impact the new biocompatible solutions may have. This review analyzes the existing literature regarding the mechanisms through which low-GDP solutions may modulate cardiovascular risk. Interventions using low-GDP solutions have provided encouraging changes in structural cardiovascular measures such as left ventricular mass (LVM), although metabolic changes from reduced GDP and AGE exposure yield inconclusive results on vascular remodelling. It is thought that the local effects of reduced glucose exposure may improve membrane integrity and therefore fluid status. Further research in the form of a robust randomized controlled trial should be carried out to assess the true extent of the cardiovascular benefits these biocompatible solutions may hold.

Introduction: The AHA notes that more than 76% of strokes are the first occurrence. There are class 1 recommendations for the management of common risk factors such as atrial fibrillation (AF), hyperlipidemia (HLD), hypertension (HTN), diabetes (DM), and vascular disease. The purpose of this study is to investigate the percentage of large vessel strokes that are potentially preventable with adequate management of vascular risk factors. Methods: A retrospective chart review was conducted on all patients undergoing endovascular therapy (EVT) from 2012-2019. Data was collected on vascular risk factors present prior to admission including HTN, DM, HLD, AF, and smoking. Preventable stroke was defined as having at least one of the following: untreated AF, untreated HLD, poorly controlled HTN (presence of left ventricular hypertrophy on transthoracic echo), history of vascular disease not on an antiplatelet agent, poorly controlled DM (A1c>10), current smoking. Groups were compared based on age, sex and 90 day functional outcomes, with favorable outcome defined as mRS ≤ 2. Results: Our sample included 396 patients who underwent EVT (mean age 65, 50% female). 42% of patients with Afib were not on anticoagulation, 31% of patients with HLD were untreated, 39% of patients with HTN were poorly controlled, 27% of patients with a history of vascular disease were not on an antiplatelet, 14% of patients with DM were poorly controlled, and 46% of all patients were smokers. In total, 78% of patients had at least 1 poorly controlled risk factor and 37% had at least 2. There was no difference in rates of preventable stroke between males and females (48% vs 52%, p=0.30) and between age groups above and below 70 (40% vs 60%, p=0.68). 64% of patients with well controlled risk factors had a favorable outcome compared to 51% with at least one poorly controlled risk factor (p=0.03). Conclusions: Our data suggests that despite guidelines on management of vascular risk factors, a large number of these are poorly controlled prior to admission for large vessel stroke, leading to a potentially preventable procedure. Not only could improved primary prevention save the wide array of resources utilized in EVT, but it could also influence long term outcomes in this cohort of patients.

Diabetes is a common risk factor for cardiovascular disease. Coronary heart disease and left ventricular dysfunction are more common in diabetic patients than in non-diabetic patients, and diabetic patients benefit less from revascularisation procedures. This increased risk can only partly be explained by the adverse effects of diabetes on established risk factors; hence, a substantial part of the excess risk must be attributable to direct effects of hyperglycaemia and diabetes. In type 2 diabetes, hyperinsulinaemia, insulin resistance and hyperglycaemia have a number of potential adverse effects, including effects on endothelial function and coagulation. Risk factor modification has been shown to reduce the occurrence of cardiovascular events in patients with diabetes; indeed, diabetic patients appear to benefit more in absolute terms than non-diabetic patients. There is thus a strong case for intensive treatment of risk factors, including insulin resistance and hyperglycaemia, in patients with type 2 diabetes.

Background: End stage renal disease (ESRD) is a well-recognized risk factor for development of sudden cardiac arrest(SCA). There is limited data on outcomes after an in-hospital SCA event in ESRD patients. Methods: Data were obtained from National Inpatient Sample from January 2007 to December 2017. In-hospital SCA was identified using International Classification of Disease, 9th Revision, Clinical Modification, and International Classification of Disease, 10th Revision, Clinical Modification codes of 99.60, 99.63, and 5A12012. ESRD patients were subsequently identified using codes of 585.6 and N18.6. Propensity -matched analysis using logistic regression with SD caliper of 0.2 was used to match patients with and without ESRD. Crude and propensity-matched (PS) cohorts outcomes were calculated. Results: A total of 1,412,985 patients sustained in-hospital SCA during our study period. ESRD patients with in-hospital SCA were younger and had a higher burden of key co-morbidities. Mortality was similar in ESRD and non-ESRD patients in PS matched cohort (70.4% vs. 70.7%, p = 0.45, figure 1) with an overall downward trend over our study years (figure 2). Conclusion: In the context of in-hospital SCA, mortality is similar in ESRD and non-ESRD patients in adjusted analysis. Adequate risk factor modification could further mitigate the risk of in-hospital SCA among ESRD patients

Abstract Background Syphilis is a sexually transmitted infection with an incidence of 14.9 cases per 100 000 persons in the USA in 2011. Untreated syphilis may remain quiescent for years but can also result in clinical sequelae, including neurosyphilis. End-stage renal disease (ESRD) patients may be at risk for syphilis due to a higher incidence of risk factors for the disease, including human immunodeficiency virus (HIV). Despite the presence of these risk factors, the incidence of syphilis in the ESRD population has not been reported. To address this issue, we investigated the incidence and risk factors for syphilis in the ESRD population using the United States Renal Data System (USRDS). Methods This study analyzed incident ESRD patients from 2004 to 2010. Based on International Classification of Diseases, Ninth Revision codes for syphilis, we determined the incidence and risk factors for syphilis following an inpatient diagnosis. Generalized linear modeling was used to examine the relative risk (RR) for the disease when controlling for demographic and other clinical risk factors. Results A total of 383 diagnoses of syphilis were identified after screening 759 066 patients. The 8-year incidence of any type of syphilis was 50.45 cases per 100 000 person-years. Other unspecified syphilis (29.77 cases per 100 000 person-years) and neurosyphilis (10.93 cases per 100 000 person-years) were the most common diagnoses. The greatest incidence was found on the East and West Coasts. Patients with the disease were younger and more likely to be black and non-Hispanic. In the final model, the adjusted RR for syphilis was significantly increased with HIV (7.61), hepatitis C (3.57), herpes simplex (2.06) and hepatitis B (1.75). Conclusions The incidence of syphilis is &gt;3-fold greater in ESRD patients when compared with the general population and is associated with sexually transmitted viral infections. Neurosyphilis is a common occurrence and is treatable, suggesting that all assessments of confusion in dialysis patients should include screening for the disease.
