New methods for identifying "at risk" patients for osteoporosis

Area of Science:

• Endocrinology
• Osteoporosis Research
• Geriatric Medicine

Background:

• Menopause is associated with accelerated bone loss.
• Osteoporotic fractures pose a significant health risk to postmenopausal women.
• Early identification of women at risk is crucial for preventative strategies.

Purpose of the Study:

• To evaluate a simple biochemical screening method for identifying fast bone losers in early postmenopause.
• To assess the efficacy of this screening in predicting future fracture risk.
• To enable timely initiation of prophylactic treatment.

Main Methods:

• Photon absorptiometry was used to measure forearm bone mineral content (BMC) over two years in 178 early postmenopausal women.
• A sequential cut-off technique analyzed body fat mass, urinary calcium and hydroxyproline, and serum alkaline phosphatase.
• The screening procedure was validated in a separate group of 70 women.

Main Results:

• The biochemical screening correctly identified 79% of fast bone losers (bone loss >3% annually).
• It also identified 78% of slow bone losers.
• The method proved effective in a new cohort of 70 women over two years.

Conclusions:

• A simple biochemical screening approach can effectively identify early postmenopausal women at high risk of rapid bone loss.
• This early identification facilitates prompt initiation of prophylactic hormone replacement therapy.
• The findings support early intervention to mitigate the risk of osteoporotic fractures.
