Background: Osteoporosis is characterized by low bone density and loss of structural integrity which can increase the risk of bone fracture and its side effects. In the recent studies, new evidences of the relationship between immune system such as TNF-&alpha and IL-17A and bone destruction have been accumulated. The aim of present study was to investigate serum level of TNF-&alpha and IL-17A in women with post-menopausal osteoporosis.

Materials and Methods: In this analytical study 40 women with post-menopausal osteoporosis and 10 healthy women were enrolled to the study based on inclusion and exclusion criteria. The serum level of TNF-&alpha and IL-17A were calculated by using ELISA method and compared between groups.

Results: The mean level of TNF-&alpha in case and control group was 957.7±479.01 and 418.09±176.7 respectively which in case group was significantly more than control group (p=0.001). The mean level of IL-17A in case and control group was 95.23±36.7 and 125.7±30.6 respectively which in case group was significantly less than control group (p=0.019).

Conclusion: The level of TNF-&alpha in women with post-menopausal osteoporosis was more than healthy women which can mention the roll of TNF-&alpha in pathogenesis of osteoporosis and potential therapeutic roll of anti TNF-&alpha agents but because of unclear roll of IL-17A in pathogenesis of osteoporosis we could not explain its mechanism in pathogenesis of osteoporosis. It seems more studies with regard to IL-17A roll in bone metabolism is required.
