Inverse correlation between fibrinogen and bone mineral density in women: Preliminary findings

Hemostatic factors may be involved in bone health. The present preliminary study investigated the association between plasma fibrinogen and bone mineral density (BMD) in perimenopausal women. A significant inverse correlation between fibrinogen and BMD was observed (correlation coefficient = -0.42, p < 0.01). This correlation appeared to be more clearly observed in the subgroup with a high level of high-sensitivity C-reactive protein than in that with a low level of high-sensitivity C-reactive protein, and in the subgroup with a high level of diacron reactive oxygen metabolites (an oxidative stress marker) than in that with a low level of diacron reactive oxygen metabolites. Thus, fibrinogen may be a possible marker of BMD in this population. More studies on the associations among hemostasis, inflammation, oxidative stress, and bone metabolism are warranted in the clinical setting.
