C-Reactive Protein and Reactive Oxygen Metabolites in Subjects with Metabolic Syndrome

Abstract

OBJECTIVE: This cross-sectional study investigated the correlation between diacron reactive oxygen metabolites (d-ROMs) and high-sensitivity C-reactive protein (hs-CRP) in subjects with or without metabolic syndrome. METHODS: Cardiometabolic risk factors, d-ROMs and hs-CRP were determined in 457 women: 123 with metabolic syndrome and 334 without metabolic syndrome. The correlation between d-ROMs and hs-CRP levels was compared between the two groups. RESULTS: The group with metabolic syndrome had significantly higher d-ROMs and hs-CRP levels than the group without metabolic syndrome. While the d-ROMs level was significantly and positively correlated with the hs-CRP level in both groups, the correlation level between the two groups was significantly different. Multiple linear regression analysis adjusted for other cardiometabolic risk factors also showed significant positive correlation between d-ROMs and hs-CRP levels in both groups. CONCLUSION: Subjects with metabolic syndrome may have a closer relationship between inflammation and oxidative stress than subjects without metabolic syndrome, possibly reflecting their increased predisposition to atherosclerosis. Further studies are necessary to confirm the observed relationship.
