<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.

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.

Persistent inflammation in end-stage renal disease (ESRD) patients is known to underlie the progression of chronic kidney disease and to be associated with multiple risk factors including malnutrition, atherosclerosis, and cardiovascular disease (CVD). The acute-phase protein pentraxin 3 (PTX3) has a proven potential as a local inflammatory biomarker, but its clinical utility in ESRD remains unclear. Circulating levels of PTX3 and classical inflammatory mediators, including the clinical prototypical C-reactive protein (CRP), were assessed in 246 ESRD patients on dialysis and analysed in relation to the lipid profile, adipokine levels, and nutritional, cardiac, and renal fibrosis markers. Occurrence of deaths was recorded for the following year. Contrarily to the classical inflammatory markers, PTX3 levels were negatively correlated with nutritional markers and associated with a less atherogenic lipid profile. Levels of the cardiac and renal fibrosis markers and of the oxidized LDL/LDL-C ratio were found to be independent determinants of PTX3 concentration. When comparing inflammatory mediators, the increase in the PTX3 levels was the only predictor of all-cause mortality in dialysis patients in a survival model adjusted to all markers under study, other than the inflammatory ones, besides common confounding factors in dialysis. Data support the clinical applicability of PTX3 as a broader inflammatory biomarker than the classical ones, presenting a close association with inflammation, malnutrition, CVD, and renal fibrosis and a great potential to predict all-cause mortality in dialysis patients. The pleiotropic character of PTX3 may be of clinical relevance, and it could be targeted to ameliorate the high morbidity and mortality associated with ESRD.

Abstract Background and aims Cancer in end-stage renal disease (ESRD) patients is an important comorbidity to be taken into consideration while planning for renal replacement therapy (RRT) options due to its associated increased mortality. This study aims to investigate the natural history and association of cancer with all-cause mortality in an ESRD population receiving dialysis. Method The study was conducted on 1271 ESRD patients receiving dialysis between January 2012 and December 2017. A comparative analysis was carried out between 119 patients with and 1152 without cancer history at entry into this study (baseline). A 1:2 (119 cancer: 238 no cancer) propensity score matched sample of 357 patients was also used for analysis. Cox-regression analysis was used to study the strength of the association between cancer and all-cause mortality. Kaplan–Meier (KM) analysis was used to demonstrate the difference in cumulative survival between the groups. A competing risk analysis was also carried out to calculate the probability of competing events (death, transplant and incident cancer). Results At baseline, 10.1% of the cohort had a history of cancer (current and past) with the annual incident rate being 1.3%. Urological cancers were the leading site of cancer. The median age of our cohort was 63 years with a predominance of males (63%) and Caucasians (79%). The majority (69%) of the cohort were receiving haemodialysis. 47% had a history of diabetes with 88% being hypertensive. During a median follow-up of 28 months, the proportion of deaths observed was similar between the groups in the matched sample (cancer 49.6 versus no-cancer 52.1%, p value 0.77). In a univariable Cox-regression model, there was no significant association between cancer and all-cause mortality (HR 1.28; 95% CI 0.97–1.67; p = 0.07). The KM estimates showed similar observations in the cumulative survival between the groups (matched sample log-rank, p value 0.85). In competing risk analysis, the cumulative probability of death at 5 years was non-significantly higher in the cancer group (cancer group 64% vs no cancer group 51%, p value 0.16). Conclusions In our real-world multi-morbid dialysis cohort of 119 cancer patients, baseline cancer history did not prove to be an independent risk factor for all-cause mortality in the first 5 years of follow-up, suggesting the need for a case-by-case approach in provision of RRT options, including transplantation.

Abstract Background and Aims End-stage renal disease (ESRD) patients frequently have the coronary artery disease. However, the short- and long-term outcome of ESRD patients with acute myocardial infarction (AMI) is little known. The aim of this study was to clarify it. Method Using the database of the Osaka Acute Coronary Insufficiency Study (OACIS), 8702 consecutive AMI patients (male: 75.2%, mean age: 66.9±12.2yrs) from 2002 to 2013 were analyzed. We classified these patients into two groups, those with ESRD [ESRD group (n=271)] and without ESRD [No-ESRD group (n=8431)] and examined in-hospital or long-term all-cause mortality. ESRD was defined as eGFR&lt;15ml/min/1.73m2. Results ESRD group had higher frequency of diabetes (59.3% vs 37.8%, p&lt;0.01), hypertension (90.1% vs 63.3%, p&lt;0.01), Killip class≧2 (40.1% vs 21%, p&lt;0.01), multi-vessel disease (69.3% vs 50.8%, p&lt;0.01), and lower frequency of peak CK&gt;3000 (21.7% vs 32.4%, p&lt;0.01) than No-ESRD group. Mean follow-up period was 1041±721 days. In hospital mortality of ESRD group was 27% and No-ESRD group 7.2%. In patients who discharged alive (8027 patients), 1-year mortality of ESRD group was 12.2% and No-ESRD group 3.3%, 3-year mortality of ESRD group was 29.3% and No-ESRD group 8.7%. Kaplan-Meier analysis revealed that the all-cause mortality (log-rank p&lt;0.01) was significantly higher in ESRD group than No-ESRD group. In ESRD patients who discharged alive (203patients), Cox univariate analysis after multiple imputation revealed that peak CK&gt;3000 was significantly associated with an increased risk of mortality (Hazard ratio 2.67, 95% confidence interval 1.18to 6.07, p=0.031). Conclusion In patients with AMI, ESRD was significantly associated with worse short- and long-term outcome, suggesting that careful treatment might be required in ESRD patients with AMI, especially had peak CK&gt;3000.

Abstract Chronic inflammation plays an important role in the progression and outcome of chronic kidney disease (CKD). The inflammatory biomarkers interleukin-6 (IL6) and pentraxin 3 (PTX3) are enhanced in CKD patients and associated with progression of the disease and higher risk for cardiovascular events, the major cause of death in these patients. Our aim was to study how the polymorphisms of their encoding genes affect the inflammatory response and outcome of end-stage renal disease (ESRD) patients on dialysis. We analyzed two single nucleotide polymorphisms (SNP), the IL6 (rs1800795) polymorphism in the promoter region (-174G/C), and the PTX3 polymorphism in the intron 1 (+ 281A/G), in ESRD patients on dialysis and in heathy individuals. The allelic frequencies, genotype distribution and their association with the circulating levels of the inflammatory markers high sensitivity C-reactive protein (hsCRP), interleukin (IL6), growth differentiation factor 15 (GDF15) and PTX3, were determined in ESRD patients; events of death were recorded along one year to evaluate all-cause mortality and the association between inflammation and the studied polymorphisms. The allelic frequencies and genotyping distribution for IL6 and PTX3 in controls and ESRD patients were similar and in agreement with European reports. For the IL6 polymorphism, we found an association of the GG and CC genotype with higher IL6 levels; the CC genotype showed also high PTX3, hsCRP and GDF15 levels. For the PTX3 polymorphism, the AA genotype was linked to the highest values of hsCRP and IL6. The mortality rate after 1-year follow-up was 10.4%. The CC genotype (IL6 polymorphism), in deceased patients, was associated to increased levels of hsCRP, IL6 and PTX3, with low levels of GDF15 and with a highest mortality risk. The AA genotype for PTX3 polymorphism, in spite of the enhancement in inflammation, showed no significant impact on mortality. Our results show that the CC genotype of the IL6 polymorphism was associated with an enhanced inflammatory state and a poorer survival rate. Both IL6 and PTX3 polymorphisms seem to modulate the inflammatory response and, therefore, disease progression and outcome. Our data also highlights the importance of research on genetic variants that, although less frequent, may have significant biological value.

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.

Background: The widespread use of hemodialysis to prolong life of end-stage renal disease (ESRD) patients has been a remarkable achievement, preventing death from uremia in these patients. The aim of the study was to find out the outcomes of haemodialysis patients with end-stage renal disease (ESRD) in low Income County. Methods: A hospital based prospective observational study was performed in the of Department of Nephrology, Shaheed Suhrawardy Medical College. Total 189 patients who stated dialysis during study period were included. All patients were monthly followed up and appropriate investigation done. All data recorded in a case record form. Study protocol approved by Ethical committeeof institute. Data analyzed in SPSS software version 25. Results: Among 189 ESRD patients on MHD selected with mean age 49.16 years (15-82), male was 60.3% and female 39.7%.Eighty eight 46.5% patient died and 39.15%(74) patient discontinue dialysis due to lack of financial support or helping assistant or social support. Three (1.6%) patients underwent renal transplantation and five patients (2.6%) transfer to other dialysis center. Average life span in dialysis 256 day (16-786 days). Most of the paints was on twice weekly dialysis 84%. Vascular access of stating dialysis was 73.8% by catheter and only 32.2% stated with AV fistula. Conclusion: A large group of patients leave dialysis due to financial or helping personal or social supportwithin 3-4 months of stating dialysis. A significant number of patients died due to multiple risk factors within 8-9 months. Identification of risk factors for early mortalityis essential and appropriatemeasure should take to prevent discontinuation at community and national level.

Abstract Background: Nephropathy associated metabolic disorder induces high incidence of fragility fracture in end-stage renal disease (ESRD) patients. As the risk factors and prognosis of fragility fracture in ESRD patients are unclear, more research is needed. This study aimed to evaluate various risk factors for ESRD-related fragility fractures, explore factors affecting the prognosis of patients with such fractures, and provide information for prevention and treatment of renal osteopathy to improve the prognosis of patients.Methods: In this retrospective case-control study, the case notes of 521 ESRD patients who received maintenance dialysis for at least 3 months were examined. Finally, 44 patients diagnosed with fragility fractures were assigned to the fragility fracture (FF) group and 192 patients were included in the control group (CG). Demographic information, underlying diseases, nutritional, bone metabolism, and renal function parameters, along with the number and causes of any deaths, were recorded for multiple statistical analysis.Results: The FF group had increased incidences of essential hypertension and diabetes mellitus and higher serum calcium, corrected calcium, alkaline phosphatase, and hemoglobin levels. Immunoreactive parathyroid hormone (iPTH), total cholesterol (TC), and low density lipoprotein (LDL) levels were higher in the CG.Conclusions: Essential hypertension and diabetes, high serum calcium and alkaline phosphatase levels, and reduced iPTH levels were risk factors for fragility fracture in ESRD patients. Maintaining iPTH and serum TC levels may protect against fragility fractures in them. Fragility fractures may yield poor prognosis and shorter lifespan. The presence of fragility fracture was an independent predictor of all-cause death in ESRD patients.

Background: Valve replacement is associated with worse outcomes in individuals who have end-stage renal disease (ESRD) and require a long-term renal replacement therapy. Prosthetic valve selection in patients with ESRD has remained controversial.Objective: We aimed to investigate long-term outcomes of mechanical and bioprosthetic valve replacement in individuals with ESRD.Methods: We conducted a population-based retrospective cohort study using data obtained from the Taiwan National Health Insurance Research Database. In total, 10,202 patients, including 912 ESRD and 9,290 non-ESRD patients, were selected after a 1:1 propensity-score matching based on the type of prosthetic valve used. The long-term mortality outcomes were then analyzed.Results: During a median follow-up period of 59.6 months, the Kaplan–Meier survival analysis revealed that ESRD patients who underwent mechanical valve replacement had higher rates of all-cause mortality and CV deaths than those who underwent bioprosthetic valve replacement (Log-rank test, p = 0.03 and 0.02, respectively). Multivariable regression analyses demonstrated that ESRD patients who underwent bioprosthetic valve replacement had lower rates of all-cause mortality (p &lt; 0.001, hazard ratio: 0.88, 95% confidence interval: 0.82–0.93) and cardiovascular (CV) death (p &lt; 0.001, hazard ratio: 0.83, 95% confidence interval: 0.76–0.90) than those who had mechanical valve replacement.Conclusion: Bioprosthetic valve replacement is significantly associated with lower rates of all-cause mortality and CV death in the ESRD population.
