Background. The aim of this study was to evaluate the possibility of identifying women with a high risk of postmenopausal osteoporosis by using computerised bone mineral analysis (CBMA) associated with markers of bone turnover in order to provide a valid and reliable screening test.
Methods. A total of 925 patients were evaluated, 252 of whom had already undergone a preliminary densitometric test six months earlier and were diagnosed as fast bone losers. 225 of them (89%) also showed altered bone turnover markers. CBMA was negative in the remaining 673 patients but 13 patients showed altered bone turnover markers and three of the latter then showed a positive CBMA 18 months later. The 673 patients who, after six months of study, were not fast bone losers were monitored over time.
Results. It emerges from these results that fast bone losers are characterised by higher levels of hydroxyprolinuria and calcium, lower levels of oestrone and estradiol, and reduced body weight compared to healthy subjects.
Conclusions. This simplified method enabled 79% of the fast bone losers to be identified, whereas densitometry identified 87.5% of the high-risk subjects. The main advantage of our simplified method compared to the measurement of bone mineral content is that it identifies the majority of fast bone losers in the initial postmenopausal period, before a substantial reduction in BMC has taken place.
