Abstract

Postmenopausal osteoporosis is characterized by rapid bone loss occurring in the post-menopausal period. The bone loss predominantly involves the trabecular bone and is brought about by an imbalance between the bone remodeling process which can be influenced by factors that could cause or contribute to osteoporosis. Pro-inflammatory cytokines (Il-1β, Il-6, IL-8 and TNF-α) have been implicated in the regulation of bone cells and play a critical role in bone remodeling. They act both directly and indirectly to increase bone resorption, and/or inhibit bone formation. The aim of the study is to determine whether pro-inflammatory cytokines correlate with bone turnover markers (BTM) in a cohort of Saudi post-menopausal women with or without osteoporosis and which BTMs will correlate with PTH and Vitamin D for use in osteoporosis diagnosis. The study is composed of 100 post-menopausal patients and 100 controls aged 50 years and above. Serum concentrations of pro-inflammatory and BTMs as well as PTH and vitamin D were determined by ELISA, Luminex and electrochemiluminescence. Serum calcium, phosphorus, glucose, and lipid profile were measured by using a chemical analyzer. There was a significant increase in the levels of pro-inflammatory cytokines, PTH, CTx, and glucose. A significantly lower vitamin D and osteocalcin levels were observed in subjects with osteoporosis than those without. No significant differences were recorded in the circulating lipid profile between groups. The present study proved that the pro-inflammatory cytokines accelerate the bone loss in postmenopausal women.

Keywords: PTH; Saudi women; bone biomarkers; osteoporosis; vitamin D.
