Serum Osteopontin Level Correlates with Carotid-Femoral Pulse Wave Velocity in Geriatric Persons

الملخص EN

Osteopontin (OPN) is involved in the regulation of vascular calcification processes.

The aim of this study was to evaluate the relationship between fasting serum OPN concentration and carotid-femoral pulse wave velocity (cfPWV) in geriatric persons.

Fasting blood samples were obtained from 93 geriatric persons.

cfPWV were performed by SphygmoCor system.

Serum OPN levels were measured using a commercially available enzyme-linked immunosorbent assay.

Geriatric adults who had diabetes (P=0.007) or dyslipidemia (P=0.029) had higher cfPWV levels than those without diabetes or dyslipidemia.

The univariable linear regression analysis showed that age (P=0.002), waist circumference (P=0.048), body mass index (P=0.004), systolic blood pressure (P=0.001), diastolic blood pressure (P=0.036), pulse pressure (P=0.017), creatinine (P=0.002), and log-OPN level (P=0.001) were positively correlated with cfPWV levels, while the high-density lipoprotein cholesterol (HDL-cholesterol) level (P=0.007) and glomerular filtration rate (P=0.001) were negatively correlated with cfPWV levels among the geriatric adults.

Multivariable forward stepwise linear regression analysis of the significant variables also showed that log-OPN (β=0.233, R2=0.123, regression coefficient: 1.868, P=0.011) was still an independent predictor of cfPWV levels in geriatric persons.
