Abstract [en]

Vasoconstrictive prostaglandins (PGs), such as PGF(2 alpha), F-2-isoprostanes, and systemic inflammation may be involved in the physiological regulation of blood pressure (BP) and the pathophysiology leading to hypertension. However, studies evaluating these parameters and BP in human populations are sparse. We analysed the cross-sectional associations between 24-hour ambulatory BP and urinary 15-keto-dihydro-PGF(2 alpha) (indicator of PG-mediated vasoconstriction and inflammation), plasma interleukin-6 (IL-6), C-reactive protein (CRP), serum amyloid A (SAA) and urinary F-2-isoprostanes (indicator of vasoconstriction and oxidative stress) in 619 men in a Swedish older population (Uppsala Longitudinal Study of Adult Men, age 78 years). Both systolic and diastolic 24-hour BP correlated inversely with concentrations of 15-keto-dihydro-PGF(2 alpha) (P < 0.01) and F-2-isoprostanes (P< 0.01) independent on other cardiovascular risk factors. Additionally, diastolic 24-hour BP inversely correlated with plasma IL-6 (P< 0.05) and 24-hour pulse pressure showed a positive linear correlation with IL-6, CRP and SAA. In conclusion, high BP is associated with decreased formation of vasoconstrictive PGF(2 alpha) and F-2-isoprostanes in this population of older men. These findings, although unlike our original hypothesis, might have an important physiological function which needs to be further evaluated.
