Osteoprotegerin and nuclear factor-kappaB ligand are associated with leptin and adiponectin levels, in apparently healthy women Academic Article uri icon


  • OBJECTIVES: We investigated the relationship between the major bone turnover markers, i.e., Osteoprotegerin (OPG) and Receptor activator of nuclear factor-kappaB ligand (RANKL) and serum adipokines (leptin, adiponectin) levels in a sample of apparently healthy women. METHODS: A random sample which consisted of 80 females (18-71 years) was studied. Elisa method was used to measure the OPG, RANKL and the leptin, adiponectin levels in females' serum. RESULTS: OPG values were inversely correlated with leptin (rho = -0.38, p = 0.002) and positively correlated with age (rho = 0.27, p=0.01) and body mass index (rho = 0.29, p=0.009). RANKL values were inversely correlated with adiponectin (rho = -0.23, p = 0.06) and age (rho = -0.30, p=0.01). Additionally, OPG was higher in post- as compared to pre-menopausal women. Further data analysis adjusting for potential confounders revealed that the OPG/RANKL ratio was positively associated with adiponectin and inversely associated with leptin levels independent of the effect of age, body mass index and menopausal status. CONCLUSIONS: These results reveal that leptin circulating levels are inversely associated with serum OPG/RANKL ratio among healthy women.
