Aim: To investigate if the serum CC motif ligand 4 (CCL4) levels are linked to disease severity in patients with postmenopausal osteoporosis (PMOP).
Patients & methods: We enrolled 66 PMOP females, 68 postmenopausal nonosteoporotic women and 67 healthy women of childbearing age. Bone mineral densities were assessed with dual x-ray absorptiometry scans. The Oswestry disability index and the visual analog scale were employed to quantify functional ability and severity of symptoms. Serum CCL4 levels were examined with a quantitative sandwich enzyme-linked immunosorbent assay.
Results: We observed a significant negative correlation of CCL4 serum levels with bone mineral density. Furthermore, serum CCL4 concentrations were significantly related to the visual analog scale and Oswestry Disability Index scores.
Conclusion: Serum CCL4 is a potential biomarker to evaluate disease severity in PMOP females.
