Cardiovascular disease (CVD) begins early in children with chronic kidney disease (CKD). Reduced nitric oxide (NO) bioavailability has been associated with increased CVD in CKD patients. Children tend to have more exposure to acrylamide, one of the most common toxins in food. We aimed to determine whether urinary levels of acrylamide metabolites N-acetyl-S-(2-carbamoylethyl)-cysteine (AAMA) and N-acetyl-S-(2-carbamoyl-2-hydroxyethyl)-cysteine (GAMA) are associated with CV risk markers in children with CKD. Data on 112 children and adolescents ages three to 18 years old with CKD stage G1–G4 are reported. We observed that 24 h ambulatory blood pressure monitoring (ABPM) abnormalities were greater, and left ventricular (LV) mass and ambulatory arterial stiffness index (AASI) were higher in children with CKD stage G2–G4 versus G1. Patients with CKD stage G2–G4 had a lower urinary acrylamide level, but a higher AAMA-to-GAMA ratio than those with CKD stage G1. Urinary acrylamide level was negatively associated with high systolic blood pressure (SBP) and diastolic BP (DBP) load on 24 h ABPM. Lower urinary levels of acrylamide, AAMA, and GAMA were correlated with LV mass. Additionally, GAMA are superior to AAMA related to NO-related parameters, namely citrulline and symmetric dimethylarginine (SDMA). This study suggests that determinations of urinary acrylamide level and its metabolites in the early stages of pediatric CKD may identify patients at risk of CVD. Further studies should clarify mechanisms underlying acrylamide exposure to define the treatment for protection against CVD.

Abstract Background The cardiovascular mortality of patients with chronic kidney disease (CKD) is 2–10 times higher than in the average population. Purpose To estimate the prevalence of abnormal cardiac function or structure across the stages CKD 1 to 5nonD. Method Prospective cohort study. Patients with CKD stage 1 to 5 not on dialysis, aged 30 to 75 (n=875) and age-/sex-matched controls (n=173) were enrolled consecutively. All participants underwent a health questionnaire, ECG, morphometric and blood pressure measurements. Blood and urine were analyzed. Echocardiography was performed. Left ventricle (LV) hypertrophy, dilatation, diastolic and systolic dysfunction were defined according to current ESC guidelines. Results 63% of participants were men. Mean age was 58 years (SD 12.6 years). Mean eGFR was 46.7 mL/min/1,73 m (SD 25.8) for patients and 82.3 mL/min/1,73 m (SD 13.4) for controls. The prevalence of elevated blood pressure at physical exam was 89% in patients vs. 53% in controls. Patients were more often smokers and obese. Left ventricular mass index (LVMI) was slightly, albeit insignificantly elevated at CKD stages 1 & 2 vs. in kontrols: 3.1 g/m2, CI: −0.4 to 6.75, p-value 0.08. There was no significant difference in LV-dilatation between patients and controls. Decreasing diastolic and systolic function was observed at CKD stage 3a and later: LVEF decreased 0.95% (CI: −1.5 to −0.2), GLS increased 0.5 (CI: 0.3 to 0.8), and OR for diastolic dysfunction increased 3.2 (CI 1.4 to 7.3) pr. increment CKD stage group. Conclusion In accordance to previous studies, we observe in the CPHCKD cohort study signs of early increase of LVMI in patients with CKD stage 1 & 2. Significant decline in systolic and diastolic cardiac function is apparent already at stage 3 CKD. Figure 1.

Cardiovascular disease (CVD) is common in chronic kidney disease (CKD), while major CV events are rare in young CKD patients. In addition to nitric oxide (NO)-related biomarkers, several surrogate markers have been assessed to stratify CV risk in youth with CKD, including 24-h ambulatory blood pressure monitoring (ABPM), carotid artery intima-media thickness (cIMT), pulse wave velocity (PWV), ABPM-derived arterial stiffness index (AASI), flow-mediated dilatation (FMD), and left ventricular mass index (LVMI). The aim of this study was to identify subclinical CVD through the analysis of indices of CV risk in children and adolescents with CKD. Between 2016 and 2018, the prospective observational study enrolled 125 patients aged 3 to 18 years with G1–G4 CKD stages. Close to two-thirds of young patients with CKD exhibited blood pressure (BP) abnormalities on ABPM. CKD children with abnormal office BP showed lower plasma arginine levels and arginine-to-asymmetric dimethylarginine (ADMA) ratio, but higher ratios of ADMA-to-symmetric dimethylarginine (SDMA) and citrulline-to-arginine. High PWV and AASI, indices of arterial stiffness, both strongly correlated with high BP load. Additionally, LV mass and LVMI exhibited strong correlations with high BP load. Using an adjusted regression model, we observed the citrulline-to-arginine ratio was associated with 24-h systolic and diastolic BP, systolic blood pressure (SBP) load, and diastolic blood pressure (DBP) load. Early assessments of NO-related parameters, BP load abnormalities, arterial stiffness indices, and LV mass will aid in early preventative care toward decreasing CV risk later in life for children and adolescents with CKD.

Background/Aims: Chronic kidney disease is a pro-inflammatory condition where the interplay between different regulatory pathways and immune cells mediates an unfavorable remodeling of the vascular wall and myocardial hypertrophy. These mechanisms include the action of CXCL12. The aim of this study is to evaluate the association between serum CXCL12 with left ventricular hypertrophy (LVH) and blood pressure control in chronic kidney disease (CKD) patients. Methods: This single-center observational study involved 90 stable CKD stage 1–5 patients (including 33 renal transplant recipients) and 25 healthy age- and sex-matched control subjects. CXCL12 was quantified by ELISA. 24-h ambulatory blood pressure monitoring was performed in 90 patients and 25 healthy controls. Left ventricular mass index (LVMI) was calculated based on the transthoracic echocardiography measurements in 27 patients out of the CKD population and in the whole control group. Results: CXCL12 correlated significantly with LVMI by multivariate regression analysis (coefficient B = 0.33, p = 0.02) together with age (B = 0.30, p = 0.03) and gender (B = 0.41, p = 0.003). A positive correlation was observed between CXCL12 and average 24-h systolic blood pressure (SBP) (rho = 0.35, p = 0.001), daytime SBP (rho = 0.35, p = 0.001), and nocturnal SBP (rho = 0.30, p = 0.002). Nocturnal hypertension was frequent (46% of CKD patients). Conclusions: The results of our study point towards a link between CXCL12 and LVH as well as blood pressure control among patients with CKD, supporting the thesis that CXCL12 may be regarded as a new potential uremic toxin.

BACKGROUND. Natriuretic peptides have cardio- and renoprotective effects, inhibiting inflammatory and proliferative processes. The role of natriuretic peptides in the early diagnosis and characterization of chronic kidney disease (CKD) and cardiovascular complications as the disease development and progresses has not been studied.TNEAIM: to study the level of natriuretic peptides in children depending on the stage of CKD development and to assess the significance of this indicator.PATIENTS AND METHODS. The study involved 93 children with congenital diseases of the urinary system at the age from 3 to 18 years. Three groups were identified: group I - 54 patients with CKD stage I , group II - 29 patients with CKD stage II; Group III - 10 children with CKD stages IV-V (patients with CKD stages IV and V were combined due to their small amount). Control group - 10 clinically healthy children of the corresponding age. The N-terminal propeptide of natriuretic hormone (NT-proBNP) was determined in the blood by the enzyme-linked immunosorbent assay.RESULTS. An increase in the level of NT-proBNP by 28.7% takes place already in the early stages of CKD. With the progression of CKD, an increase in the level of NT-proBNP was noted from 57.4 % in children in the group of patients with stage I CKD to 80 % in children in group III patients. The maximum concentrations of NT-proBNP, many times higher than those in CKD stages I and II, were observed in children with CKD stages IV-V. The degree of increase in the level of NT-proBNP correlated with the severity of CKD.CONCLUSION. In the diagnosis and characterization of CKD and cardiorenal syndrome in children, the determination of the level of natriuretic peptides is of great importance. A high level of natriuretic peptides characterizes the presence of cardiorenal relationships and can be used as an additional criterion for assessing the severity of CKD, including at the early stages of its development.

Abstract: 967 employees of locomotive crews (drivers and their assistants of the Sverdlovsk railway of JSC «Russian Railways») were examined. It was revealed that CKD occurs in 12, 09% of employees of locomotive crews. As the CKD stage increases, the progression of changes in the cardiovascular system was found in locomotive crew workers. A high percentage of the prognostically unfavorable variant of left ventricular remodeling - eccentric myocardial hypertrophy (25% - 39.1%, depending on the stage of CKD) was found. These changes may be a factor of adverse cardiovascular events in employees of locomotive crews, which must be taken into account when admitting to professional activities.

Abstract Background and Aims The structure and function of the left ventricle (LV) are affected since the early stages of chronic kidney disease (CKD). Our cross-sectional study aimed to estimate the echocardiographic indices of the LV diastolic function and the evaluation of their potential correlation with indices of kidney injury in patients with CKD, before initiation of renal replacement therapy. Method 99 patients with CKD (stage 2 CKD: 31 patients (27%), stage 3 CKD: 47 patients (40.9%) and stage 4 CKD: 37 patients (32.1%)) were enrolled in the study. Anthropometric data, indices of renal function (eGFR-CKD-EPI, urinary protein excretion in mg/24h), biochemical laboratory parameters, comorbidities [hypertension (HT), diabetes mellitus (DM), coronary heart disease (CAD)] and echocardiographic indices of LV diastolic function were recorded. In specific, left atrial (LA) dimensions were measured in M-Mode and were expressed both as absolute values in mm as well as indexed to body surface area ((BSA) and expressed as the LA index in mm/m2. The study sample, after taking into account patient gender, was further divided into separate groups according to the presence or not of LA dilation. Results The average patient age was 62 +/- 13 years and average eGFR (CKD-EPI) was 44.1+/-21.4 ml/min/1.73m2. With regard to comorbidities, 59.3% of the sample population had arterial hypertension, 24.3% had diabetes mellitus and 10.4% had known coronary artery disease. Regarding anti-hypertensive and hypolipidemic treatment, 22.6% of the patients were on ARB and 24% on ACEi, 51.3% on CCB, 29.6% on β-blockers, 37.4% on diuretics and 28.7% of the patients were receiving statin treatment. 28.2% of the patients had dilated LA in terms of absolute value and 13.8% had dilated LA following indexing to BSA (LA index). A positive correlation was observed between the LA size and age (p=0.001), BMI (p=0.041), uric acid levels (p=0.022), PTH (p=0.029), fibrinogen (p=0.035), LV mass (p=0.006) and LV mass/BSA (p=0.005), whereas a negative correlation was observed with serum LDL (p=0.027). Additionally, there was observed a negative correlation of LA index with eGFR (p=0.05), as well as an inverse relationship between LA index and PTH (p=0.012), age (p=0.004), BMI (p=0.037) and LV mass/BSA (p=0.005). No significant correlations between LA size and LA index with proteinuria or with co-morbidities (DM, HT, CAD) were observed. Conclusion In a population of patients with stage 2-4 CKD, LA size correlated to indices of CKD. Larger studies are required in order to further confirm these correlations.

Background: Central blood pressure (BP) assessed noninvasively considerably underestimates true invasively measured aortic BP in chronic kidney disease (CKD) patients. The difference between the estimated and the true aortic BP increases with decreasing estimated glomerular filtration rates (eGFR). The present study investigated whether aortic calcification affects noninvasive estimates of central BP. Methods: Twenty-four patients with CKD stage 4–5 undergoing coronary angiography and an aortic computed tomography scan were included (63% males, age [mean ± SD ] 53 ± 11 years, and eGFR 9 ± 5 mL/min/1.73 m2). Invasive aortic BP was measured through the angiography catheter, while non-invasive central BP was obtained using radial artery tonometry with a SphygmoCor® device. The Agatston calcium score (CS) in the aorta was quantified on CT scans using the CS on CT scans. Results: The invasive aortic systolic BP (SBP) was 152 ± 23 mm Hg, while the estimated central SBP was 133 ± 20 mm Hg. Ten patients had a CS of 0 in the aorta, while 14 patients had a CS >0 in the aorta. The estimated central SBP was lower than the invasive aortic SBP in patients with aortic calcification compared to patients without (mean difference 8 mm Hg, 95% CI 0.3–16; p = 0.04). The brachial SBP was lower than the aortic SBP in patients with aortic calcification compared to patients without (mean difference 10 mm Hg, 95% CI 2–19; p = 0.02). Conclusion: In patients with advanced CKD the presence of aortic calcification is associated with a higher difference between invasively measured central aortic BP and non-invasive estimates of central BP as compared to patients without calcifications.

Abstract Background Occurrence of cardiovascular disease (CVD) in the setting of chronic kidney disease (CKD) can be described as a “cruel alliance”, with CVD responsible for about half of all deaths among CKD patients. Chronic kidney disease patients are more likely to die from CVD than progress to end stage kidney disease (ESKD). Dyslipidaemia, a known traditional risk factor for CVD, is highly prevalent among CKD patients and with an even higher frequency among ESKD patients on dialytic therapies. Prolonged exposure of continuous ambulatory peritoneal dialysis (CAPD) patients to high glucose concentrations in CAPD fluid have been associated with increased risk of cardiovascular events. In this study, we investigated the relationship of atherosclerotic vascular disease (AsVD) to clinical and echocardiographic parameters among black South Africans with CKD (stage 3) and ESKD on CAPD and haemodialysis (HD). Methods This was a cross-sectional study of 40 adult (18–65 years) non-diabetic CKD patients (kidney disease outcome quality initiative [KDOQI] stage 3), 40 ESKD patients on CAPD, 40 ESKD patients on HD and 41 age and sex-matched healthy controls. An interviewer-administered questionnaire was used to obtain information on participants’ sociodemographic and cardiovascular risk factors. Anthropometric parameters were measured. Serum blood samples were analysed for creatinine, albumin and lipid profile; lipoprotein ratios, Framingham’s risk score and the 10-year risk of developing coronary heart disease (CHD) were calculated. Echocardiography was performed on all patients and carotid intima media thickness (CIMT) was measured in both right and left carotid arteries at 1 cm proximal to the carotid bulb. Spearman’s rank correlation and binary logistic regression were conducted to determine the relationship of AsVD to clinical and echocardiographic parameters. Results Atherosclerotic vascular disease was most prevalent among ESKD patients on CAPD (70%, n = 28/40). Chronic kidney disease and HD patients exhibited a similar prevalence (47.5%, n = 19/40), while the prevalence in controls was 17.1% (n = 7/41). Presence of AsVD was associated with significantly older age, higher waist hip ratio (WHR), left ventricular mass index (LVMI) and Framingham’s 10-year risk of developing CHD. Significant differences in clinical and echocardiographic parameters were observed when the study groups were compared. Age and LVH independently predicted AsVD. Conclusion Atherosclerotic vascular disease was more prevalent among CAPD patients compared to pre-dialysis CKD and HD patients. Among all lipoprotein ratios assessed, non-HDL-C showed the most consistent significant difference between the groups. Age (> 40 years) and presence of LVH were independent predictors of AsVD.

Endothelial dysfunction (ED) and oxidative stress are potential new pathomechanisms of cardiovascular diseases in patients with chronic kidney disease (CKD). The aim of the study was to assess the association between endothelial dysfunction, oxidative stress biomarkers, and cardiovascular risk factors in children with CKD. Serum oxidized LDL (oxLDL), protein carbonyl group, urea, creatinine, cystatin C, thrombomodulin, asymmetric dimethylarginine (ADMA), von Willebrand factor, brain natriuretic peptide (BNP), lipids, high sensitivity C-reactive protein, intercellular adhesion molecule-1 levels, and albuminuria were measured. Anthropometric, ambulatory blood pressure (BP) measurements and echocardiography were performed. The studied group consisted of 59 patients aged 0.7–18.6 (mean 11.1) years with stages 1 to 5 CKD. Thrombomodulin strongly correlated with creatinine (R=0.666; p<0.001), cystatin C (R=0.738; p<0.001), BNP (R=0.406; p=0.001), ADMA (R=0.353; p=0.01), oxLDL (R=0.340; p=0.009), 24-hour systolic (R=0.345; p=0.011) and mean (R=0.315; p<0.05) BP values, and left ventricular mass index (LVMI, R=0.293; p=0.024) and negatively with estimated glomerular filtration rate (R=−0.716; p<0.001). In children with CKD, TM strongly depended on kidney function parameters, oxLDL levels, and 24-hour systolic and mean BP values. Thrombomodulin seems to be a valuable marker of ED in CKD patients, correlating with CKD stage as well as oxidative stress, BP values, and LVMI.

Objective: to determine the role of serum Klotho (s-Klotho) protein levels changes in patients with different stages of chronic kidney disease (CKD).Methods: The study involved 130 patients with CKD stages 1–5D (mean age ― 41±6.7 years). Serum levels of parathyroid hormone (PTH), calcium, phosphorus and s-Klotho protein (ELISA method) at baseline and after 1 year of follow-up were examined in all the patients so as the blood pressure (BP), including central (aortic), pulse wave velocity ― with the help of «Sphygmоcor» (Australia), echocardiography, radiography of the abdominal aorta in a lateral projection were also performed.Results: when comparing the s-Klotho levels in patients with different CKD stages, it was found that the level change associated with the reduction of glomerular filtration rate (GFR) ahead of phosphorus and PTH increase in serum, stared at 3A CKD, whereas hyperphosphatemia and PTH increase started at 4–5 CKD stages. According to ROC analysis, decreasing of s-Klotho levels below 387 pg/ml was indicated a calcification risk of abdominal aorta increased with an 80% sensitivity and 75% specificity. In addition, a strong negative relationship of low s-Klotho levels and heart remodeling was found. When comparing the patients with hypertension who were receiving antihypertensive monotherapy, the highest serum levels of Klotho protein were observed in those of them whose target blood pressure level was achieved primarily through Angiotensin II Receptors Blockers (ARB), compared to those who was administered another drug group (p0.01) or has not reached the target blood pressure level (p=0,008).Conclusion: The change of serum Klotho levels (decrease) in CKD progression is associated with the degree (increase) of cardiovascular calcification and remodeling (the development of left ventricular hypertrophy, and cardiomyopathy) and it can be seen as an early independent marker of the cardiovascular system lesions in CKD. Our preliminary data of the effect of blood pressure correction on s-Klotho levels may indicate the possibility of drug maintaining serum Klotho levels and it requires further research.
