Arterial stiffness in mild-to-moderate CKD.

ABSTRACT: Whether arterial stiffness correlates with mild-to-moderate CKD and albuminuria in the community is unclear. We studied the association between arterial stiffness and mild-to-moderate CKD and albuminuria in the Framingham Heart Study. CKD was present in 6.7% (181 of 2682) of participants and microalbuminuria was present in 8.2% (479 of 5818). The measures of arterial stiffness were the carotid femoral pulse wave velocity, forward pressure wave amplitude, central pulse pressure, augmentation pressure, augmentation index, and mean arterial pressure. In cross-sectional analyses, arterial stiffness did not associate with CKD (defined by estimated GFR <60 ml/min/1.73 m(2)) in either age- and gender-adjusted or multivariable-adjusted linear regression models. Carotid femoral pulse wave velocity associated with both urinary albumin-to-creatinine ratio and microalbuminuria (P < 0.0001 after multivariable adjustment). In longitudinal analyses, we used logistic regression models to examine the associations between baseline arterial stiffness measures (exposure variables) and incident CKD or microalbuminuria (n = 1675 for CKD analyses and n = 1252 for microalbuminuria analyses). Baseline arterial measures did not associate with incident CKD or incident microalbuminuria. In summary, arterial stiffness correlates with albuminuria but not with mild-to-moderate CKD.

Project description:BackgroundArterial stiffness is an independent predictor of all-cause and cardiovascular mortality in patients with chronic kidney disease (CKD). There are limited prospective data however on progression of arterial stiffness in CKD, including evaluating associations with bone mineral markers such as fibroblast growth factor 23 (FGF23) and soluble α-klotho (sKl).MethodsIn this prospective, single-center, observational study, arterial stiffness [measured by pulse wave velocity (PWV)] and hormones influencing mineral homeostasis, including serum FGF23 and sKl, were compared between non-dialysis CKD stages 4/5 and healthy controls at baseline and 12 months (12 m). Abdominal aortic calcification (AAC) was quantitated using lateral lumbar radiography at baseline.ResultsForty patients with CKD [mean estimated glomerular filtration rate (eGFR) 19.5 ± 6.7 mL/min/1.73m2] and 42 controls (mean eGFR 88.6 ± 12.9 mL/min/1.73m2) completed follow-up. There were no differences in age, gender and body mass index between groups. A significant increase in FGF23 [240.6 (141.9-1129.8) to 396.8 (160.3-997.7) pg/mL, p = 0.001] was observed in the CKD group but serum phosphate, corrected calcium, parathyroid hormone and sKl did not change significantly over 12 m. At baseline, CKD subjects had higher AAC prevalence [83.8% versus (vs.) 43.6%, p = 0.002] and higher aortic PWV [9.7(7.6-11.7) vs. 8.1 (7.2-9.7) m/s, p = 0.047] compared to controls. At 12 m, aortic PWV increased by 1.3 m/s (95% confidence interval, 0.56 to 2.08, p < 0.001) in the CKD cohort, with 30% of subjects showing progression from normal aortic elasticity to stiffening (PWV > 10 m/s). Serum FGF23 was associated with AAC, abnormal PWV and progression of PWV at 12 m.ConclusionsArterial stiffness and serum FGF23, both of which are associated with increased cardiovascular risk, increased over one year in individuals with CKD. Additionally, a significant association was found between serum FGF23 and arterial calcification and stiffness. Larger clinical studies and further experimental work are warranted to delineate the temporal relationship as well as the pathological mechanisms linking FGF23 and vascular disease.
