Background: Pulse wave velocity is a measurement of arterial stiffness and associated with increased cardiovascular mortality. Previous reports in peritoneal dialysis have linked increased pulse wave velocity with an expansion in extracellular water. As cardiovascular mortality is increased in peritoneal dialysis patient, we wished to determine whether changes in pulse wave velocity mirrored changes in extracellular water. Methods: We repeated aortic pulse wave velocity and bioimpedance-derived extracellular water measurements in peritoneal dialysis patients attending for assessment of peritoneal membrane function. Results: Sixty-six patients, 41 males (62.1%), mean age of 66.2 ± 13.9 years, median duration of peritoneal dialysis treatment (14.3 (3.1–31.9) months) had repeated measurement 6.4 (5.8–10.2) months apart, with no significant change in aortic pulse wave velocity (10.1 ± 3.2 to 9.9 ± 2.8 m/s). In univariate analysis, the initial aortic pulse wave velocity was associated with extracellular water (r = 0.26, p = 0.034) and serum N-terminal pro brain-type natriuretic peptide (r = 0.25, p = 0.04), and on follow-up, aortic pulse wave velocity with N-terminal pro brain-type natriuretic peptide (r = 0.31, p = 0.01). Aortic pulse wave velocity increased in 50% of patients, and these patients had greater serum C-reactive protein 3(2–10) versus 2(1–4) mg/L, and ferritin (778(444–1099) versus 585(313–811), p < 0.05), but there were no differences in either absolute or adjusted extracellular water. Both log C-reactive protein (odds ratio 4.7 (95% confidence limits 1.3–17.1), p = 0.019) and prescription of calcium channel blockers (odds ratio 4.9 (95% confidence limits 1.2–19.1), p = 0.024) were independently associated with an increase in aortic pulse wave velocity. Conclusion: We did not find an independent association between a change in aortic pulse wave velocity and extracellular water, suggesting that changes in aortic stiffness in peritoneal dialysis patients are more complex than simply following changes in extracellular water.

Background/Aims: Possible predictive value of aortic-brachial arterial stiffness mismatch assessed by pulse wave velocity PWV ratio in peritoneal dialysis patients’ outcomes need to be further elucidated. The aim of this study is to investigate the predictor value of PWV ratio on peritoneal dialysis (PD) patients’ outcomes in China. Methods: In this longitudinal cohort study, patients who started PD during September 20, 2005, to February 05, 2008, were included. All the patients were followed until January 31, 2018. Aortic-brachial arterial stiffness mismatch was assessed using carotid-femoral pulse wave velocity divided by carotid-radial pulse wave velocity (PWV ratio). Results: A total of 181 incident PD patients were included. The median survival of patients in PWV ratio above median group (4.03 years, 95% CI 4.64-7.99 years) was shorter than that of PWV ratio below median group (10.43 years, 95% CI 9.74-11.12 years, p< 0.001). The cardiovascular mortality rate in PWV ratio above median group were significantly higher than that of PWV below median group (log rank test, p< 0.001). Univariate Cox regression analysis showed that both PWV ratio (HR 2.42, 95% CI 1.80-3.25, p< 0.001) and CF-PWV (HR 1.27, 95% CI 1.16-1.38, p< 0.001) were associated with high patients’ all-cause mortality. Multivariable Cox regression analysis showed that the PWV ratio was a strong and significantly predictor of cardiovascular mortality (HR 2.08 95% CI 1.16-3.71, p=0.014) after adjusting for coronary heart disease history (HR 2.39, 95% CI 1.20-4.76, p=0.013), diabetes mellitus history (HR 2.84, 95% CI 1.51-5.33, p=0.001). However, the CF-PWV was failed to be included as a significant predictor for both all-cause and CVD mortality in the multivariable Cox regression model. Conclusion: Aortic-brachial arterial stiffness mismatch as assessed by PWV ratio, a new arteries stiffness risk parameter, is a significant prognostic indicator of CVD mortality in PD patients. We demonstrated that the discriminative power of the PWV ratio for both all-cause and CVD mortality was better than that CF-PWV.

AbstractElevated pulse wave velocity (PWV) reflects increased arterial stiffness. Several studies have investigated PWV in peritoneal dialysis (PD) patients, but direct comparisons with healthy controls were not done. The potential influence of peritoneal transport characteristics on arterial stiffness in PD patients was suggested in recent studies. The aims of this study were to compare PWV in PD patients and healthy volunteers, and to investigate factors associated with increased PWV. The carotid-femoral PWV was measured in 28 PD patients and 28 healthy controls, matched for age and gender. A peritoneal equilibration test (PET) was performed in all PD patients. Based on the PET, patients were classified as: high transporters (H) (n=8), high-average (HA) (n=12), low-average (LA) (n=6), and low transporters (L) (n=2). Six of the PD patients were diabetic. PWV was significantly higher in the PD patients than in the controls (9,9±2,4 vs. 8,0±0,9; p=0,0004). In the PD group, PWV was higher in H/HA than in L/LA patients (10,4 ± 2,5 vs. 8,6 ± 1,0; p=0,008), but all the diabetic patients were in the H/HA group. PWV was significantly higher in diabetic than in non-diabetic PD patients (12,8 ± 2,0 vs. 9,1 ± 1,7; p=0,004). In the PD patients, significant positive correlations were found between PWV and: age, pulse pressure, Kt/V, and duration of PD therapy. In conclusion, the carotid-femoral PWV is elevated in peritoneal dialysis patients. Increased PWV in PD patients is associated with age, diabetic status, and longer duration of PD therapy, but not with this type of peritoneal transport.

Calcification Score

The objective of this study was to evaluate the correlation of bone mineral density (BMD), evaluated by DXA, with vascular calcifications, arterial stiffness, and vascular disease in patients on peritoneal dialysis. Vascular calcifications were evaluated by vascular calcification score on plain x ray, and arterial stiffness was measured by pulse wave velocity using the Complior device (Artech Medical, Pantin, France). Adjusting for multiple factors, lower BMD at the femoral neck, but not at the lumbar spine, was associated with higher pulse wave velocity ( p = 0.037), higher vascular calcification score ( p = 0.013), and peripheral artery disease ( p = 0.006). These data reinforce the hypothesis of the existence of a link between bone disease and cardiovascular disease in dialysis patients.
