Cytokine has been postulated to play a role in the pathogenesis of post-menopausal osteoporosis. To test this hypothesis we measured circulating levels of IL-1, IL-6,IL-8 and TNF-alpha in 98 post-menopausal women (30 age matched normal and 68 osteoporotic) with no vertebral fractures. Although the cytokine levels of patients were found in normal cut off values, the difference in cytokine levels between patients and controls was statistically significant for IL-1 and IL-8 (p < 0.01). In osteoporotic patients, none of the cytokines correlated with lumbar, femoral (neck) and total hip bone mineral densities and also with body mass index (p > 0.01). In conclusion, we were unable to demonstrate abnormalities of cytokines affecting bone resorption in peripheral serum of women with post-menopausal osteoporosis. However increased production of these cytokines may occur in the local environment of bone.
