Summary
Low-dose oestrogen replacement therapy via implants preserves bone mineral density in postmenopausal women. This bone-preserving effect continues into advanced age, counteracting age-related bone loss.
Area of Science:
- Endocrinology
- Bone Metabolism
- Gerontology
Background:
- Postmenopausal osteoporosis is a significant health concern.
- Estrogen deficiency contributes to bone loss.
- Long-term efficacy of estrogen replacement therapy (ERT) in advanced age requires investigation.
Purpose of the Study:
- To evaluate the sustained bone-preserving effects of low-dose subcutaneous oestradiol implants.
- To determine if these benefits persist into advanced age.
Main Methods:
- Cross-sectional clinical study comparing postmenopausal women on long-term oestradiol implants with age-matched non-users.
- Bone mineral density (BMD) measured at distal forearm, vertebrae, and hip.
- Serum oestradiol and follicle-stimulating hormone (FSH) levels analyzed.
Main Results:
- Implant users exhibited 20-25% higher BMD at all measured sites compared to non-users (P < 0.0001).
- These BMD increases remained significant after adjusting for confounders.
- Longer treatment duration positively correlated with higher BMD, compensating for age-related decline.
Conclusions:
- Continuous, long-term, low-dose oestradiol implant therapy effectively preserves both compact and cancellous bone.
- The bone-preserving effect persists into advanced age, mitigating inevitable age-related bone loss.
