Uric acid correlates to oxidation and inflammation in opposite directions in women

Abstract

Objective: To evaluate the association of uric acid (UA) levels with a panel of markers of oxidative stress and inflammation.

Methods: Plasma UA levels, along with a panel of oxidative stress and inflammatory markers, were measured in 755 Chinese women.

Results: Plasma UA levels were inversely associated with urinary levels of the oxidative stress marker F₂-isoprostanes and positively correlated to levels of inflammatory markers, such as C-reactive protein and some proinflammatory cytokines (tumor necrosis factor-α and interleukin-6) in blood as well as prostaglandin E₂ metabolites in urine.

Conclusions: Plasma UA levels correlate to oxidation and inflammation biomarkers in opposite directions in women.
