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.

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.

Abstract Background and Aims Changes in dietary phosphorus regulate serum FGF-23, parathyroid hormone, 1,25(OH)(2)D and Klotho concentrations . Cardiovascular disease (CVD) is the principal killer of patients with chronic kidney disease and hyperphosphetemia is a potent risk factor it. Of many causative factors for CVD in CKD, dietary interventions involving restriction of dietary phosphorous intake can help reduce onset of CVD at early stages of CKD with other corrective measures. Muscle wasting is a consequence of uremic syndrome which alters body composition. The aim of the study was to study effect of dietary phosphorous restriction on FGF-23, iPTH, Klotho, 1,25(OH)(2)D and body composition in chronic kidney disease patients. Method This is a longitudinal study with 12 months intervention, approved by Ethics Committee of the institute. A total 132 subjects were recruited (66 healthy controls, 66 CKD patient. of 66 patients 33 were in CKD stage 1 and 33 in stage 2. GFR was calculated with the help of MDRD formula. Biochemical parameters of subjects were evaluated at baseline, 6 and 12 months along with the anthropometric measurements (body weight, height, mid upper arm circumference (MUAC), and skin folds). Three days dietary recall was taken to evaluate energy, protein and phosphorous intake. CKD patients whose dietary phosphorous intake was more than 1000 mg/day, were given intense dietary counseling and prescribed dietary modifications by restricting dietary phosphorous between 800-1000 mg/day. Results The mean age of controls and patients was 37.01±9.62 and 38.27±12.06 and eGFR of 136.94±11.77 and 83.69±17.37 respectively. One way ANOVA showed significant difference among controls and the study groups in hemoglobin (p<0.001), s albumin (p<0.001), FGF-23 (p<0.001), klotho (p<0.001), urinary protein (p<0.001) and Nephron Index (p<0.001).The mean energy intake (p = 0.001) and dietary phosphorous intake (p<0.001) of the CKD patients decreased significantly with the decline in the renal function along with the anthropometric measures i.e. BMI (p = 0.041),WHR (p = 0.015) and all four skin folds (p<0.001). On applying Pearson’s correlation, eGFR correlated negatively with urinary protein (-0.739, 0.000), FGF-23 (-0.679, 0.000) and serum phosphorous (-0.697, 0.000) and positively with klotho (0.872, 0.000). FGF-23 correlated negatively with klotho (-0.742, 0.000). Dietary phosphorous was found to be positively correlated with urinary protein (0.496, 0.000), serum phosphorous (0.680, 0.000) and FGF-23 (0.573, 0.000) and negatively with Klotho (-0.602, 0.000). Nephron index revealed a positive correlation with eGFR (0.529, 0.000). Urinary protein correlated negatively with klotho (-0.810, 0.000). A multiple linear regression was run to predict eGFR from anthropometric variables such as BMI, WHR, MUAC, skin folds thickness and handgrip strength. All anthropometric variables predicted decline in eGFR (p<0.05, R2 =0.223). At 6 and 12 months; repeated ANOVAs analysis showed a statistically significant difference in serum creatinine (p=0.000), serum phosphorous (p=0.000), FGF-23(p=0.000) and klotho (p=0.000). Conclusion Elevated levels of FGF-23 and decreased Klotho levels, with the moderate decline in renal function improved with the restricted phosphorous diet at 6 and 12 months emphasizing the importance of phosphorus restriction at an early stage.

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.

BACKGROUND: Heart failure (HF) and Chronic kidney disease (CKD) are major public health problems that often co-exist with a resultant high mortality and morbidity. Most of the studies evaluating their reciprocal prognostic impact have focused on mortality in majority populations. There is limited literature on the impact of CKD on HF morbidities in ethnic minorities. AIMS: Our study seeks to compare HF outcomes in patients with or without CKD in an African-American predominant cohort. METHODS: We obtained data from the NGH at Meharry Heart Failure Cohort; a comprehensive retrospective HF database comprised of patient care data (HF admissions, non-HF admissions, and emergency room visits) were assessed from January 2006 to December 2008. The study group consist of 306 subjects with a mean age of 65±15 years. 81% were African-American (AA), 19% Caucasian and 48.5% are females. Following the NKF KDOQI guidelines, 5 stages of CKD were outlined based on GFR. RESULTS: The overall prevalence of CKD in this population is 54.2%. CKD stage 1 was most prevalent with 45.8%, prevalence for stages 2-5 are 21.6%, 18.3%, 9.5% and 4.9% respectively. The comparison of the mean of ER visits, non HF hospitalizations and HF hospitalizations between normal and CKD patients was done using independent t-test and showed no significant difference in the mean number of ER visits (p=0.564), or HF hospitalizations(p=0.235). However, there is a statistically significant difference in the mean number of non -HF hospitalizations between normal and CKD patients (p=0.031). CONCLUSION: This study shows that the prevalence of CKD in this minority -predominant HF cohort is similar to prior studies in majority populations. However, only the non-HF hospitalizations were significantly increased in the CKD group. Future prospective studies will be needed to define the implications of this in the management of HF patients with CKD.

Abstract Background Arterial damage in chronic kidney disease (CKD) is characterized by aortic stiffness. This is seen in elderly patients with advanced CKD. The association between arterial stiffness and early CKD is not well established. Objective: We aimed to study arterial stiffness using pulse wave velocity (PWV) among patients with chronic kidney disease (CKD) stage 2 to 4 and normal renal function in younger-age population. Design and Method: Patients with confirmed CKD stage 2 to 4 were recruited from various clinics from Universiti Teknologi MARA Medical Center, Sungai Buloh, Malaysia from 1st August 2015 until 31st January 2018. Sociodemographic and anthropometric indices were recorded on recruitment. Each patient underwent carotid-femoral (aortic) PWV measurement to determine arterial stiffness. PWV is determined using a one-probe device (SphygmoSore XCEL). Results: 87 patients with CKD stage 2–4 and 87 control patients were recruited. The mean age was 47 ± 5.4 years. CKD patients had a higher mean PWV (7.8 m/s ± 1.7) than healthy controls (5.6 m/s ± 1.0) (p < 0.001, 95% CI –2.59, –1.77). There was significant difference of mean PWV between control (5.6 m/s ± 1.0) and CKD stage 2 (7.6 m/s ± 1.5) (p < 0.001, 95% CI –2.40, –1.49). Our results showed a stepwise increase in PWV from control subjects, CKD stage 2 through stage 4 (p < 0.001). The mean difference of PWV between CKD stage 2 (7.6 m/s, ± 1.5) and stage 4 (9.0 m/s, ± 0.8) was 1.43 (p < 0.001, 95% CI –2.50, -0.35). There was significant difference of mean PWV between diabetes mellitus (DM) (8.2 m/s ± 1.8) and non-DM (7.3 m/s ± 1.3) patients with CKD stage 2–4 (p = 0.022, 95% CI –1.50, –0.12). Mutiple linear regression analysis showed only age (β = 0.078, p = 0.014), mean arterial pressure (MAP) (β = 0.031, p = 0.007) and diuretics usage as the combination antihypertensive medication (β = 0.839, p = 0.018) were independently associated with PWV (r2 = 0.249, p < 0.001). Conclusions: This study shows that arterial stiffness as assessed by PWV occurs early in CKD patient and increased arterial stiffness occurs in parallel with decline of glomerular filtration rate in patients with mild-to-moderate CKD of younger age population.
