Even though visfatin has been suggested as a proinflammatory adipokine, there are few studies of the relationship between plasma visfatin concentrations and proinflammatory markers in the nondiabetic population. We showed that plasma visfatin concentrations were positively associated with circulating interleukin-6 levels and diastolic blood pressure independent of obesity in nondiabetic healthy Korean women. These results suggest that circulating visfatin may be related with some proinflammatory condition even in a nondiabetic state.
