Introduction
The aim was to analyse data on the use of biochemical bone turnover markers (BTM) in postmenopausal osteoporosis.
Methods
We carried out a comparative analysis of the most important papers concerning BTM in postmenopausal osteoporosis that have
been published recently.
Results
The BTM levels are influenced by several factors. They are moderately correlated with BMD and subsequent bone loss. Increased
levels of bone resorption markers are associated with a higher risk of fracture. Changes in the BTM during the anti-osteoporotic
treatment (including combination therapy) reflect the mechanisms of action of the drugs and help to establish their effective
doses. Changes in the BTM during the anti-resorptive treatment are correlated with their anti-fracture efficacy.
Conclusion
Biological samples should be obtained in a standardised way. BTM cannot be used for prediction of the accelerated bone loss
at the level of the individual. BTM help to detect postmenopausal women who are at high risk of fracture; however, adequate
practical guidelines are lacking. BTM measurements taken during the anti-resorptive therapy help to identify non-compliers.
They may improve adherence to the anti-resorptive therapy and the fall in the BTM levels that exceeds the predefined threshold
improves patients’ persistence with the treatment. There are no guidelines concerning the use of BTM in monitoring anti-osteoporotic
therapy in postmenopausal women.
