Physiological Evaluation of Osteopontin and Bone Alkaline Phosphatase as Metabolic Markers in Postmenopausal Women with Osteoporosis

Osteoporosis is a pathological condition that results from a disruption in the dynamic balance of bone remodeling, involving complex interactions between resorption and formation markers at the cellular level. These interactions are influenced by various molecular and hormonal factors, ultimately leading to an increased rate of bone resorption that surpasses bone formation. The assessment of bone turnover markers is considered a critical tool in the management and monitoring of patients with osteoporosis. Among the established biochemical indicators, bone-specific alkaline phosphatase (B-ALP) and osteopontin (OPN) serve as reference markers for bone formation and resorption. The present study was conducted on postmenopausal women diagnosed with osteoporosis in Basrah Province, Iraq. This study set out to examine the correlation between osteoporosis and blood concentrations of two important biomarkers, bone alkaline phosphatase (B-ALP) and osteopontin (OPN), in women who had just gone through menopause. After menopause, 80 blood samples were taken from women: 55 from those who had osteoporosis and 25 from those who were considered healthy. Patient samples were also distributed into two categories depending on age and disease severity. The results of the statistical analysis showed that compared to healthy persons, osteoporotic patients had significantly higher levels of osteopontin (P < 0.001). In addition, the T-test revealed that the serum B-ALP concentration was significantly lower in the osteoporotic group than in the control group. The results of this research indicate that changes in the blood levels of B-ALP and OPN are important for postmenopausal women to be able to recognise and track the course of osteoporosis early on. These findings support the potential use of B-ALP and OPN as early biochemical indicators for monitoring postmenopausal osteoporosis.
