Immune mediators serum levels are distinctly associated with
osteoporosis in male and female patients
Abstract
Introduction: Osteoporosis is a chronic and progressive disease caused
by an imbalance in the bone remodeling process. In this process,
resorption and formation are performed by osteoclasts and osteoblasts,
respectively. This delicate balance is regulated by several hormones and
cytokines. Thus, to attain a better understanding of the bone remodeling
associated process with osteoporosis in aging subjects, the following
mediators were investigated: cytokines, chemokines and
metalloproteinase-3 (MMP-3). Patients and Methods: To this end, blood
samples were collected from 30 osteoporotic patients, cytokines,
chemokines and MMP-3 were measured with the help of ELISA and CBA.
Results: Men with osteoporosis had significantly higher levels of MMP-3
and decreased levels of CCL5 than women. Women with osteoporosis had
significantly higher levels of IL-33 compared to adult males. Discussion
and conclusion: The different immunological factors seem to act
differently in osteoporosis evaluated separately in men and women. An
increase in MMP-3 and decreased CCL5 may be an important factor in
osteoporosis in men, whereas the disease seems to be associated with an
increase in IL-33 in women.
