Increased serum myoglobin levels were previously found in patients with chronic renal failure. In this report we have studied the effects of dialysis on myoglobin elimination in patients on CARD, IPD, cuprophan and polyacrylonitrile (PAN) membrane hemodialysis. Peritoneal dialysis removed a significant amount of myoglobin, CAPD 480 ± 65 μg/day, IPD 270 ± 25 μg/12 h treatment, while with cuprophan dialysis none, and with PAN dialysis only an insignificant amount of myoglobin. The serum myoglobin levels were 250 ± 18 and 264 ± 14 μg/l on cuprophan and a 3 month dialysis on PAN membrane, respectively. Markedly increased serum levels were also found in CAPD and IPD patients on peritoneal dialysis, 227 ± 25 and 286 ± 32 μg/l respectively. This study has shown that there is an increased serum myoglobin concentration in end-stage kidney disease patients on dialysis. Although peritoneal membrane is permeable to myoglobin, a relatively small amount is removed, and the serum level in CAPD and IPD patients was not significantly different from the serum myoglobin concentration in hemodialysis patients. Furthermore myoglobin could not be removed by hemodialysis membrane and an analysis of its important extrarenal catabolism level points were analyzed.

Introduction: Cardiovascular disease is frequent in end-stage kidney disease patients, and is a major cause of morbidity and mortality. This study was carried out to assess the comparative cardiac effects of hemodialysis and continuous ambulatory peritoneal dialysis on left ventricular function.Methods: A prospective observational study was carried out in patients undergoing hemodialysis or continuous ambulatory peritoneal dialysis at least for 6 months. The duration of the study was from June 2019 to May 2020. CAPD consists of 3 to 4 exchanges/day and haemodialysis 2-3 times/week for 4 hours. Baseline characteristics age, gender, dialysis duration, hypertension, diabetes and hyperlipidaemia were collected. The same cardiologist performed all echocardiography at the end of hemodialysis session in hemodialysis patients and after the drain of dialysate in peritoneal dialysis patients.Results: Sixty patients (40 hemodialyses, 20 peritoneal dialyses) were enrolled. The mean age of the patient was 53.71±13.00 years (range 25-76). There was a slightly higher number of male in the hemodialysis group (p= 0.065). Systolic and diastolic blood pressure were significantly higher in hemodialysis groups (p<0.001). Regarding left ventricular parameters, hemodialysis patients had a higher prevalence of left ventricular diastolic dysfunction, left ventricular hypertrophy, left ventricular mass compared to peritoneal dialysis patients. Pericardial effusion and thickening were present higher in hemodialysis patients and was statistically significant (p<0.05).Conclusion: The modality of dialysis influence left ventricular function. Left ventricle dysfunction is prevalent among hemodialysis patients compared to peritoneal dialysis. Echocardiographic follow up is essential as this could improve the management of cardiovascular complications in dialysis patients.

Background: The newly introduced device Mobil-O-Graph (IEM, Stolberg, Germany) combines brachial cuff oscillometry and pulse wave analysis, enabling the determination of pulse wave velocity (PWV) via complex mathematic algorithms during 24-h ambulatory blood pressure monitoring (ABPM). However, the determinants of oscillometric PWV in the end-stage kidney disease (ESKD) population remain poorly understood. Methods: In this study, 81 ESKD patients undergoing long-term peritoneal dialysis underwent 24-h ABPM with the Mobil-O-Graph device. The association of 24-h oscillometric PWV with several demographic, clinical and haemodynamic parameters was explored using linear regression analysis. Results: In univariate analysis, among 21 risk factors, 24-h PWV exhibited a positive relationship with age, body mass index, overhydration assessed via bioimpedance spectroscopy, diabetic status, history of dyslipidaemia and coronary heart disease, and it had a negative relationship with female sex and 24-h heart rate. In stepwise multivariate analysis, age ( β: 0.883), 24-h systolic blood pressure (BP) ( β: 0.217) and 24-h heart rate ( β: −0.083) were the only three factors that remained as independent determinants of 24-h PWV (adjusted R 2 = 0.929). These associations were not modified when all 21 risk factors were analysed conjointly or when the model included only variables shown to be significant in univariate comparisons. Conclusion: The present study shows that age together with simultaneously assessed oscillometric BP and heart rate are the major determinants of Mobil-O-Graph-derived PWV, explaining >90% of the total variation of this marker. This age dependence of oscillometric PWV limits the validity of this marker to detect the premature vascular ageing, a unique characteristic of vascular remodelling in ESKD.

Background The rate of sudden cardiac death in the hemodialysis population exceeds that of the general population by >20‐fold. Hemodialysis patients may be particularly susceptible to sudden cardiac death provoked by drug‐induced QT prolongation because of their substantial cardiovascular disease burden, exposure to electrolyte shifts during dialysis, and extensive polypharmacy. However, population‐specific data regarding the frequency and patterns of QT prolonging medication use are limited. Methods and Results We conducted a descriptive drug utilization study using 3 administrative databases, the United States Renal Data System, MarketScan, and Medicare claims. We characterized the extent and patterns of QT prolonging medication use by adult hemodialysis patients and individuals without end‐stage kidney disease annually from 2012 to 2016. We also identified instances of high‐risk QT prolonging medication use among hemodialysis patients. In total, 338 515 hemodialysis patients and 40.7 million individuals without end‐stage kidney disease were studied. Annual utilization rates of QT prolonging medications with known torsades de pointes risk in hemodialysis patients were ~1.4 to ~2.5 times higher than utilization rates in individuals without end‐stage kidney disease. Hemodialysis patients with demographic and clinical risk factors for drug‐induced QT prolongation were exposed to medications with known torsades de pointes risk more often than patients without risk factors. Conclusions Hemodialysis patients use QT prolonging medications with known torsades de pointes risk more extensively than individuals without end‐stage kidney disease. Given the widespread use and instances of high‐risk prescribing, future studies evaluating the cardiac safety of these drugs in the hemodialysis population are needed.

Background Large epidemiological studies have demonstrated an early survival advantage with the initiation of peritoneal dialysis (PD) compared to haemodialysis (HD). Chronic inflammation may contribute to atherosclerosis and cardiovascular (CVD) mortality in end-stage kidney disease (ESKD). We hypothesize that the initiation of HD in ESKD patients is associated with a greater inflammatory response compared with PD. Aims To examine the effects of initiating HD and PD upon inflammation and CVD risk markers in ESKD patients. Methods We per formed a pilot prospective study on 75 predialysis CKD stage-5 subjects comparing the effects of HD and PD upon high sensitivity C-reactive protein (hsCRP), interleukin(IL)-12, IL-18 and pulse wave velocity (PWV). Study visits were conducted 3 – 6 months before (baseline) and after (follow-up) initiation of dialysis Results Thirty-nine and 36 patients were initiated on HD and PD respectively. HD patients were older than PD patients (65.1 ± 2.1 vs 57.7 ± 2.7 years; p = 0.03) but had similar baseline systolic blood pressure (SBP), pulse pressure (PP), hsCRP, IL-12, IL-18, and PWV. At follow-up, HD patients had significantly increased hsCRP levels [5.2(3.7, 7.3) vs 1.7(1.0, 2.8)g/L; p < 0.001] compared to PD. Follow-up blood pressure, IL-12, IL-18, and PWV were similar between groups. A significant association remained between hsCRP and HD after adjustment for age, previous CVD, and residual urine output. Conclusion The initiation of HD was associated with significantly increased hsCRP compared to PD. Further study is required to determine the plausibility of inflammation as a potential underlying contributor to the observed early mortality difference between dialysis modalities.

Background: This retrospective cohort study investigated the characteristics and outcomes of the end-stage kidney disease (ESKD) patients treated with incremental peritoneal dialysis (PD) at a large academic centre. Methods: ESKD patients initiating PD with a dialysate volume ≤6 L/day were analysed. Results: One hundred and seventy-five patients were included and were followed up for 352.6 patient-years. The baseline residual kidney function (RKF) was 8.3 ± 3.4 mL/min/1.73 m2. The unadjusted 1- to 5-year patient survival rate was 89.6%, 80.4%, 65.4%, 62.7% and 48.8%, respectively, and the corresponding time on PD therapy rate was 95.1%, 89.1%, 89.1%, 82.4% and 77.6%. Greater initial PD dose (hazard ratio = 1.608, 95% confidence interval 1.089–2.375) was associated with death after adjusting for age, Charlson comorbidity index (CCI), haemodialysis prior to PD, assisted PD and baseline RKF, likely as a result of residual confounding. There was no association with PD discontinuation. The average peritonitis rate and hospitalisation rate were 0.122 and 0.645 episodes per patient-year, respectively. The dialysate volume increased from 4.5 (4.3–5.7) L/day to 8.0 (6.0–9.8) L/day at 5 years. Fifty-seven (32.6%) patients graduated to full-dose PD at a median time of 10.3 (6.2, 15.7) months. Male sex, greater body mass index and lower baseline serum albumin were risk factors for increasing PD dose to over 6 L/day within 1 year. Conclusions: Incremental PD is a safe approach to initiate dialysis, and it offers satisfactory outcomes. Close monitoring, comprehensive evaluation of clinical responses and prompt adjustment of the prescription as needed play a crucial role in this patient-centred treatment.

Abstract Introduction Blood Pressure (BP) control is largely unsatisfied in End Stage Kidney Disease (ESKD) principally due to sodium retention. Peritoneal Dialysis (PD) is the most common type of home dialysis, using a peritoneal membrane to remove sodium, though sodium removal remains challenging. Methods This is a case-study reporting two consecutive ESKD patients treated by a novel peritoneal PD solution with a mildly reduced sodium content (130 mmol/L) to treat hypertension. Results In the first case, a 78-year-old woman treated by Continuous Ambulatory PD (CAPD) with standard solution (three 4 h-dwells per day 1.36% glucose 132 mmol/L) showed resistant hypertension confirmed by ambulatory blood pressure monitoring (ABPM), reporting 24 h-BP: 152/81 mmHg, day-BP:151/83 mmHg and night-ABP: 153/75 mmHg, with inversion of the circadian systolic BP rhythm (1.01), despite use of three anti-hypertensives and a diuretic at adequate doses. No sign of hypervolemia was evident. We then switched from standard PD to low-sodium solution in all daily dwells. A six-months low-sodium CAPD enabled us to reduce diurnal (134/75 mmHg) and nocturnal BP (122/67 mmHg), restoring the circadian BP rhythm, with no change in ultrafiltration or residual diuresis. Diet and drug prescription were unmodified too. The second case was a 61-year-old woman in standard CAPD (three 5 h-dwells per day) suffering from hypertension confirmed by ABPM (mean 24 h-ABP: 139/84 mmHg; mean day-ABP:144/88 mmHg and mean night-ABP:124/70 mmHg). She was switched from 132-Na CAPD to 130-Na CAPD, not changing dialysis schedule. No fluid expansion was evident. During low-sodium CAPD, antihypertensive therapy (amlodipine 10 mg and Olmesartan 20 mg) has been reduced until complete suspension. After 6 months, we repeated ABPM showing a substantial reduction in mean 24 h-ABP (117/69 mmHg), mean diurnal ABP (119/75 mmHg) and mean nocturnal ABP (111/70 mmHg). Ultrafiltration and residual diuresis remained unmodified. No side effects were reported in either cases. Conclusions This case-report study suggests that mild low-sodium CAPD might reduce BP in hypertensive ESKD patients.
