Objectives: This study was planned to evaluate the prognostic impact of end-stage renal disease (ESRD) in patients with critical leg ischemia (CLI) undergoing infrainguinal revascularization. Materials and Methods: 1425 patients who underwent infrainguinal revascularization for CLI were the subjects of the present analysis. Ninety-five patients had ESRD (eGFR < 15 ml/min/m2), and of them 66 (70%) underwent percutaneous transluminal angioplasty and 29 (30%) underwent bypass surgery. Results: ESRD patients had significantly lower overall survival (at 3-year, 27.1% vs. 59.7%, p < 0.0001), leg salvage (at 3-year, 57.7% vs. 83.0%, p<0.0001), and amputation free survival (at 3-year, 16.2% vs. 52.9%, p < 0.0001) than patients with no or less severe renal failure. The difference in survival was even greater between 86 one-to-one propensity matched pairs (at 3-year, 23.1% vs. 67.3%, p < 0.0001). ESRD was an independent predictor of all-cause mortality (RR 2.46, 95%CI 1.85–3.26). Logistic regression showed that age ≥ 75 years was the only independent predictor of 1-year all-cause mortality (OR 4.92, 95%CI 1.32–18.36). Classification and regression tree analysis showed that age ≥ 75 years and, among younger patients, bypass surgery for leg ulcer and gangrene were associated with significantly higher 1-year mortality. Conclusions: Lower limb revascularization in patients with CLI and end-stage renal failure is associated with favourable leg salvage. However, these patients have a very poor survival and this may jeopardize any attempt of revascularization. Further studies are needed to identify ESRD patients with acceptable life expectancy and who may benefit from lower limb revascularization.

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 Background End-stage renal disease (ESRD) is the most severe stage during the development of the renal failure. And depression is the most common psychological disorder in patients with ESRD, which in turn aggravates the progression of renal failure and seriously reduce the quality of life in ESRD patients with depression, but its underlying mechanism remains unclear. This study aimed to reveal the pathogenesis and discover novel peripheral biomarkers for ESRD with depression through metabolomics analysis.Methods Ultra-high-performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS) was used to explore changes of serum metabolites among healthy controls (n = 12), ESRD patients (n = 17), and ESRD patients with depression (n = 17). Also, the differential metabolites between groups were subjected to clustering analysis, pathway analysis, receiver operating characteristic (ROC) curve analysis.Results A total of 57 significant serum differential metabolites were identified between the ESRD without depression group and the ESRD with depression group, which were involved in 19 metabolic pathways, such as energy metabolism, glycerolipid metabolism and glutamate-centered metabolism. Moreover, the area under the ROC curve of Gentisic acid, Uric acid, 5-HT, 2-Phosphoglyceric acid, Leucyl-phenylalanine, Propenoyl carnitine, Malaoxon, Pregnenolone, 6-Thioxanthine 5'-monophosphate, Hydroxyl ansoprazole, Zileuton O-glucuronide, Cabergoline, PA (16:0/18:2(9Z,12Z)), PG (18:0/18:1(11Z)), probucol, etc. and their combination was greater than 0.90.Conclusions Inflammation, oxidative stress and metabolic abnormalities in energy metabolism, glycerolipid metabolism and glutamate-centered metabolism may be associated with the pathogenesis of ESRD with depression, which may be promising targets for therapy. Furthermore, the identified differential metabolites may serve as biomarkers for the diagnosis of ESRD patients with depression.

Background: End stage renal disease patients are treated with dialysis in Nepal. But there is no renal registry to indicate the burden of disease in the country. Objectives: The objective of this study is to find out the incidence of ESRD on renal replacement therapy and their out come. Materials and methods: It is a retrospective analysis (audit) of all ESRD patients who had received dialysis inside Nepal and had under gone transplantation from 1990 to 1999. The haemodialysis (HD) registry, HD patients file, intermittent peritoneal dialysis (IPD) registry of Bir Hospital, Shree Birendra Hospital, Tribhuwan University Teaching hospital and National Kidney Center were reviewed. Acute renal failure and acute on chronic renal failure were excluded and the demographic profile, dialysis session, dialysis duration and outcome of all ESRD patients were computed. One patient was counted only once in spite of attending more than one center for dialysis. SPSS package was used for analysis. Results: Total number of 1393 ESRD patients received renal replacement therapy (RRT) in the decade. Mean age of patients were 46.7 ± 16.7 with 70% of ESRD were between 20-60 years age with male: female ratio of 1.8:1. Initial mode of RRT was IPD in 58.2%, HD in 41.7% and pre-emptive transplantation in 0.1% patients. Records of 189 patients could not be found and out of remaining 1208 patients, 85.8% received dialysis for < 3 months, 6% received dialysis for more than a year and 9.5% had undergone kidney transplantation. The incidence of ESRD had increased gradually with 3.4 per million populations (pmp) in 1990 to 11.89 pmp in 1999 with an average annual incidence of 6 pmp and only 0.31% of expected ESRD patients received RRT. Conclusion: The incidence of ESRD is increasing but majority discontinue or die within 3 months. Dialysis centers needs to be expanded to different parts of country and prospective studies have to be carried out to find out of cause of ESRD and to institute preventive measures.Key words: End stage renal disease; Renal replacement therapy; Haemodialysis; Intermittent peritoneal dialysis; Incidence of end stage renal disease; Nepal.

Protein Catabolic Rate

Abstract This study aimed to estimate causal effect of normalized protein catabolic rate (nPCR) on mortality among end stage renal disease (ESRD) patients in the presence of time-varying confounding affected by prior exposure using g-estimation. Information about 553 ESRD patients was retrospectively collected over 8 years, from 2011 to 2019, from hemodialysis facilities at Kerman, southeast of Iran. nPCR was dichotomized to &lt; 1.2 versus ≥ 1.2 g/kg per day. Then standard time-varying accelerated failure time (AFT) Weibull model was built, and results were compared with those generated by g-estimation. After appropriately adjusting for time-varying confounders, weighted g-estimation yielded 78% shorter survival time (95% confidence interval [95% CI]: -81% to -73%) in patients under continuous nPCR &lt; 1.2 than those who had nPCR ≥ 1.2 g/kg per day during the follow-up, though it was 18% (95% CI: -57% to +54%) in Weibull model. Moreover, the hazard ratio estimates of 4.56 (95% CI: 3.69 to 5.37), and 1.20 (95% CI: 0.66 to 2.17) were obtained by weighted g-estimation and Weibull model, respectively. G-estimation indicated that inadequate dietary protein intake characterized by nPCR increases all-cause mortality among ESRD patients, but the Weibull model provided a substantially biased effect estimate towards the null.

Rationale : Patients with end-stage renal disease are characterized by increased cardiovascular and all-cause mortality because of advanced remodeling of the macrovascular and microvascular beds. Objective : The aim of this study was to determine whether retinal microvascular function can predict all-cause and cardiovascular mortality in patients with end-stage renal disease. Methods and Results : In the multicenter prospective observational ISAR study (Risk Stratification in End-Stage Renal Disease), data on dynamic retinal vessel analysis were available in a subcohort of 214 dialysis patients (mean age, 62.6±15.0; 32% women). Microvascular dysfunction was quantified by measuring maximum arteriolar dilation and maximum venular dilation (vMax) of retinal vessels in response to flicker light stimulation. During a mean follow-up of 44 months, 55 patients died, including 25 cardiovascular and 30 noncardiovascular fatal events. vMax emerged as a strong independent predictor for all-cause mortality. In the Kaplan-Meier analysis, individuals within the lowest tertile of vMax showed significantly shorter 3-year survival rates than those within the highest tertile (66.9±5.8% versus 92.4±3.3%). Univariate and multivariate hazard ratios for all-cause mortality per SD increase of vMax were 0.62 (0.47–0.82) and 0.65 (0.47–0.91), respectively. Maximum arteriolar dilation and vMax were able to significantly predict nonfatal and fatal cardiovascular events (hazard ratio, 0.74 [0.57–0.97] and 0.78 [0.61–0.99], respectively). Conclusions : Our results provide the first evidence that impaired retinal venular dilation is a strong and independent predictor of all-cause mortality in hemodialyzed end-stage renal disease patients. Dynamic retinal vessel analysis provides added value for prediction of all-cause mortality and may be a novel diagnostic tool to optimize cardiovascular risk stratification in end-stage renal disease and other high-risk cardiovascular cohorts.

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.
