Asymmetric dimethylarginine (ADMA) and its enantiomer, Symmetric dimethylarginine (SDMA), are naturally occurring amino acids that were first isolated and characterized in human urine in 1970. ADMA is the most potent endogenous inhibitor of nitric oxide synthase (NOS), with higher levels in patients with end-stage renal disease (ESRD). ADMA has shown to be a significant predictor of cardiovascular outcome and mortality among dialysis patients. On the other hand, although initially SDMA was thought to be an innocuous molecule, we now know that it is an outstanding marker of renal function both in human and in animal models, with ESRD patients on dialysis showing the highest SDMA levels. Today, we know that ADMA and SDMA are not only uremic toxins but also independent risk markers for mortality and cardiovascular disease (CVD). In this review, we summarize the role of both ADMA and SDMA in chronic kidney disease along with other cardiovascular risk factors.

Gastrointestinal (GI) bleeding is more common in patients with chronic kidney disease and is associated with higher mortality than in the general population. Blood losses in this patient population can be quite severe at times and it is important to differentiate anemia of chronic diseases from anemia due to GI bleeding. We review the literature on common causes of lower gastrointestinal bleeding (LGI) in chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. We suggest an approach to diagnosis and management of this problem.

BackgroundChronic kidney disease (CKD) is known to increase the risk of atrial fibrillation (AF) development, but the relationship between AF and subsequent renal function decline in patients with CKD is not well understood. In this study, we explored the role of AF on renal outcomes among patients with CKD.MethodsIn a retrospective hospital-based cohort study, we identified patients with CKD aged ≥20 years from 1 January 2008 to 31 December 2018. The patients were divided into AF and non-AF groups. We matched each patient with CKD and AF to two non-AF CKD controls according to propensity scores. The outcomes of interest included estimated glomerular filtration rate (eGFR) decline of ≥20%, ≥30%, ≥40% and ≥50%, and end-stage renal disease (ESRD).ResultsAfter propensity score matching, 6731 patients with AF and 13 462 matched controls were included in the analyses. Compared with the non-AF group, the AF group exhibited greater risks of eGFR decline ≥20% (HR 1.43; 95% CI 1.33 to 1.53), ≥30% (HR 1.50; 95% CI 1.36 to 1.66), ≥40% (HR 1.62; 95% CI 1.41 to 1.85) and ≥50% (HR 1.82; 95% CI 1.50 to 2.20), and ESRD (HR 1.22; 95% CI 1.12 to 1.34). Higher CHA2DS2-VASc scores were associated with greater risks of eGFR decline and ESRD.ConclusionsIn patients with CKD, AF was associated with greater risks of subsequent renal function decline. CHA2DS2-VASc scores may be a useful risk stratification scheme for predicting the risk of renal function decline.

Chronic kidney disease (CKD) is a worldwide public health problem. Patients with CKD have a number of disorders in the organism, and the presence of oxidative stress and systemic inflammation in these patients is the subject of numerous studies. Chronic inflammation joined with oxidative stress contributes to the development of numerous complications: accelerated atherosclerosis process and cardiovascular disease, emergence of Type 2 diabetes mellitus, development of malnutrition, anaemia, hyperparathyroidism, and so forth, affecting the prognosis and quality of life of patients with CKD. In this review we presented the potential role of the myeloperoxidase enzyme in the production of reactive/chlorinating intermediates and their role in oxidative damage to biomolecules in the body of patients with chronic kidney disease and end-stage renal disease. In addition, we discussed the role of modified lipoprotein particles under the influence of prooxidant MPO intermediates in the development of endothelial changes and cardiovascular complications in renal failure.

Previous systematic reviews elucidate the efficacy of Tai Chi on the rehabilitation and treatment for various chronic diseases. Yet, no consensus has been reached on its efficacy and safety from those with chronic kidney disease (CKD). Therefore, we conducted a systematic review to critically summarize what is already known about the prevailing benefits of Tai Chi for CKD patients. There was no evidence that Tai Chi had adverse effects on CKD patients. Long-term Tai Chi exercises could improve quality of life, cardiorespiratory fitness, and physical motor function for the end-stage renal disease (ERSD) patients undergoing dialysis. Regular Tai Chi exercises might exert modest influences in delaying CKD progression for mild–moderate CKD patients. However, there is insufficient evidence to demonstrate positive effects of Tai Chi exercises on bone health of the ESRD patients. Accordingly, rigorously designed, longer-term studies of Tai Chi are warranted to identify its efficacy on CKD patients across different stages, especially targeting potential mechanisms in terms of Tai Chi altering biological gene profile expressions.

End-stage renal disease (ESRD) patients undergoing renal replacement therapy have a high mortality rate and suffer from considerable morbidity. Degree of nutritional decline, disordered mineral metabolism, and vascular calcification are some of the abnormalities that predict an adverse outcome for ESRD patients. All these abnormalities begin early during the course of chronic kidney disease (CKD), long before the need for maintenance dialysis. Thus, CKD represents a continuum of metabolic and vascular abnormalities. Treatment of these abnormalities early during the course of CKD and a timely initiation of dialysis have the potential of improving patient outcomes. However, the thesis that successful management of these abnormalities will favorably modify the outcomes of dialysis patients remains untested. The proportion of incident USA ESRD patients starting chronic peritoneal dialysis (CPD) has historically been low. Limited physician training and inadequate predialysis patient education appear to underlie the low CPD take-on in the USA. Furthermore, two key changes have occurred in the USA: steep decline in CPD take-on and progressive increase in the use of automated peritoneal dialysis. The decline in CPD take-on has afflicted virtually every subgroup examined and has occurred, paradoxically, when the CPD outcomes in the country have improved. Understanding the reasons for historically low CPD take-on and recent steep declines in utilization may allow the development of plans to reverse these trends.

Purpose. Nontraditional cardiovascular risk factors as apolipoprotein A (ApoA), apolipoprotein B (ApoB), and the proprotein convertase subtilisin/kexin type 9 (PCSK9) increase the prevalence of cardiovascular mortality in chronic kidney disease (CKD) or in end-stage renal disease (ESRD) through quantitative alterations. This review is aimed at establishing the biomarker (ApoA, ApoB, and PCSK9) level variations in uremic patients, to identify the studies showing the association between these biomarkers and the development of cardiovascular events and to depict the therapeutic options to reduce cardiovascular risk in CKD and ESRD patients. Methods. We searched the electronic database of PubMed, Scopus, EBSCO, and Cochrane CENTRAL for studies evaluating apolipoproteins and PCSK9 in CKD and ESRD. Randomized controlled trials, observational studies (including case-control, prospective or retrospective cohort), and reviews/meta-analysis were included if reference was made to those keys and cardiovascular outcomes in CKD/ESRD. Results. 18 studies met inclusion criteria. Serum ApoA-I has been significantly associated with the development of new cardiovascular event and with cardiovascular mortality in ESRD patients. ApoA-IV level was independently associated with maximum carotid intima-media thickness (cIMT) and was a predictor for sudden cardiac death. The ApoB/ApoA-I ratio represents a strong predictor for coronary artery calcifications, cardiovascular mortality, and myocardial infarction in CKD/ESRD. Plasma levels of PCSK9 were not associated with cardiovascular events in CKD patients. Conclusions. Although the “dyslipidemic status” in CKD/ESRD is not clearly depicted, due to different research findings, ApoA-I, ApoA-IV, and ApoB/ApoA-I ratio could be predictors of cardiovascular risk. Serum PCSK9 levels were not associated with the cardiovascular events in patients with CKD/ESRD. Probably in the future, the treatment of dyslipidemia in CKD/ESRD will be aimed at discovering new effective therapies on the action of these biomarkers.

In recent decades, the prevalence of chronic kidney disease (CKD) in the population has a clear upward trend. This is due, first of all, to an increase in the frequency of occurrence of the main factors leading to its development: diabetes mellitus and arterial hypertension. The progression of CKD against the background of the action of these factors leads to a steady loss of the kidneys of their filtration capacity and the development of complications associated with this process. These include, first of all, metabolic and acid-base disorders, electrolyte abnormalities, uremic intoxication, overhydration, protein-energy wasting, sarcopenia and others. Most of them are involved in the development of endothelial dysfunction and the formation of cardiovascular remodeling (CVR), as a key component of the cardiorenal continuum. At the same time, there is a mutual negative influence of pathology of the cardiovascular system on renal function and manifestations of CKD on cardiovascular hemodynamics. This “vicious circle” leads to the development of end-stage renal disease and an increase in cardiovascular risk and mortality from diseases of the circulatory system in patients with advanced stages of CKD. In this connection, this work is devoted to the study of the role of uremic intoxication and, in particular, indoxyl sulfate, in the development of CVR in patients with CKD at different stages of the disease.

Abstract An increase in bleeding is observed in patients with chronic kidney disease (CKD) and end stage renal disease (ESRD) despite the normal coagulation profile and fibrinogen level. The hemostatic deficit in these patients may due to the defects in fibrin formation. The fibrinokinetic profile of CKD (n=50) and ESRD patients on hemodialysis prior to and after dialysis was measured. Citrated plasma from each patient was supplemented with 25 μl of 5 U thrombin and 25 μl of 0.05 M CaCl. The rate of fibrin formation was measured by monitoring the optical density (OD) at 405 nM. After reaching steady state, 50 μl of urokinase (30,000 U/ml) was added to measure the fibrinolytic profile. Forty normal male and female individuals were also analyzed. In addition PT, aPTT and fibrinogen levels were also measured. The normal male and female fibrinokinetic profile showed a strong clot formation with the clot reaching an average OD of 1.2±0.3 (range 0.7–1.4). In the CKD patients a much weaker clot was formed with an average OD of 0.21±0.13 (range 0.05–0.41). In the ESRD patients on maintenance hemodialysis, the pre-dialysis sample showed a weaker fibrinokinetic profile reaching near normal levels with a clot density of 1.3±0.4 (range 0.8–1.6). In the urokinase induced fibrinolysis assay, the CKD patients plasma exhibited a much stronger fibrinolytic index in comparison to the normal population (80% clot lysis vs. 20%). In the ESRD patients the clot lysis profile was relatively weaker in comparison to the CKD patients, suggesting that hemodialysis may contribute to impaired clot formation. These results are contrary to the reported observations that dense clot resistant to fibrinolysis are formed in CKD and ESRD patients. Furthermore the clot sobserved in these patients were highly susceptible to lysis. The maintenance hemodialysis results in improving the fibrinokinetic and fibrinolytic profile in the ESRD patients. Therefore maintenance hemodialysis contributes to improved hemostasis in ESRD patients.

Background: Self-management is the latest multidisciplinary intervention that empowers end-stage renal disease (ESRD) patients to be active in maintaining their health status. The implementation of self-management among ESRD patients undergoing hemodialysis in Indonesia remains relatively low, contributing to the high prevalence of complications and morbidity. The social cognitive theory proposes that social support is one of the environmental factors affecting health behavior change. Therefore, this study aimed to investigate the association between social support and self-management among ESRD patients undergoing hemodialysis in Indonesia.Design and Methods: A cross-sectional study was conducted among 107 ESRD patients selected by consecutive sampling. Data were collected online from four chronic kidney disease communities in Indonesia in June 2020. Medical Outcome Study Social Support Survey and Hemodialysis Self-Management Instrument were used to measure patients’ functional social support and self-management levels. Statistical analysis using the Chi-square test was applied to evaluate the association between social support and self-management.Results: More than half of the patients had high social support (51%) and good self-management (53%). There was a significant relationship between social support and self-management (p = 0.027; α = 0.05; odds ratio 95% CI = 2.386). Conclusions: Social support is a potential environmental factor that can be modified to enhance health behavior change among ESRD patients in Indonesia, with the specific behavior being self-management. This study recommends functional social support as an integral part of self-management intervention provided through cooperation between health workers, chronic kidney disease community, and patient companions.
