Skeletal scintigraphic changes in osteoporosis treated with sodium fluoride: concise communication
Summary
Sodium fluoride (NaF) treatment in postmenopausal osteoporotic women revealed appendicular skeletal responses via total skeletal scintigraphy. This sensitive imaging technique detected increased uptake in peripheral bones, indicating NaF
Area of Science:
- Endocrinology
- Bone Metabolism
- Radiology
Background:
- Osteoporosis is a significant health concern in postmenopausal women.
- Sodium fluoride (NaF) has been investigated for its potential effects on bone density.
Purpose of the Study:
- To evaluate the appendicular skeletal response to sodium fluoride (NaF) treatment in postmenopausal osteoporotic women.
- To determine the sensitivity of total skeletal scintigraphy in detecting these responses.
Main Methods:
- Twelve postmenopausal osteoporotic women received NaF (88 mg/day) and calcium (1500 mg/day).
- Total skeletal scintigrams were performed before and during the treatment period.
- Changes in serum alkaline phosphatase activity were monitored.
Main Results:
- All 12 patients demonstrated new areas of increased radiotracer uptake in the appendicular skeleton, particularly in metaphyseal regions and short bones.
- The distal femur and proximal tibia were the most frequently affected sites.
- Increased serum alkaline phosphatase activity was observed in nine patients, and seven developed bone pain.
Conclusions:
- Total skeletal scintigraphy is a sensitive method for detecting the peripheral skeletal response to NaF.
- NaF treatment can induce changes in the appendicular skeleton of osteoporotic women.
- Further research is warranted to understand the clinical implications of these scintigraphic findings.
