In the present study, we aimed to investigate the association between circulating levels of high sensitive C-reactive protein (hs-CRP) and various biomarkers for hepatic, diabetic, and cardiovascular health. The retrospective analysis included 438 individuals who were tested for these panels simultaneously at Vibrant America Clinical Laboratory. The study population included free-living individuals without any preexisting clinical conditions. Among the cardiovascular markers, a positive correlation and significant association was found between high levels of hs-CRP and serum levels of triglycerides (r = 0.0964, p −0.1423, p −0.1216, p < 0.0105) with circulating levels of hs-CRP. Among all the diabetic markers, glucose (r = 0.1547, p < 0.0011) and glycated serum protein (r = 0.1725, p < 0.0003) were positively correlated with circulating hs-CRP. In the hepatic panel, AST, a transaminase that plays a vital role in amino acid metabolism, was found to have a strong positive correlation with hs-CRP (r = 0.2139, p < 0.0001). In conclusion, the results clearly show the association of hs-CRP with diabetic, hepatic, and cardiovascular risk factors indicating its central value as a key marker for several lifestyle-associated disorders.展开更多

Little is known about the relations of homocysteine and high-sensitivity C-reactive protein （hs-CRP） to arterial stiffness in the Chinese community. The aim of the present study was to investigate the association of plasma homocysteine and hs-CRP levels with arterial stiffness in a community-based cohort. Methods We related levels of homocysteine and hs-CRP to four measures of arterial stiffness （carotid-femoral pulse wave velocity （PWV）, carotid-radial PWV, carotid-ankle PWV and heart rate corrected augmentation index） in 1680 participants from two communities of Beijing, China. Arterial stiffness was measured within two days of the time of biomarker measurement. Results In univariate analysis, homocysteine was positively associated with the carotid-femoral PWV （r=0.211, P 〈0.0001）, carotid-radial PWV （r=0.120, P 〈0.0001） and carotid-ankle PWV （r=0.148, P 〈0.0001）, whereas it was inversely related to the augmentation index （r= -0.052, P=0.016）. Hs-CRP was positively associated with the carotid-femoral PWV （r=0.074, P=0.001） and carotid-ankle PWV （r=0.050, P=0.02）. In multiple-adjusted models （R2=0.57）, homocysteine levels remained a significant determinant of the carotid-femoral PWV （standardized 13=0.065, P=0.007）, whereas the association of hs-CRP with measurements of arterial stiffness was not present. Conclusions In the Chinese population, plasma homocysteine levels are associated with alterations of aortic stiffness, whereas plasma levels of hs-CRP are not independently related to artery stiffening.展开更多
