Study Notes
Laboratory Tests for Bone Health
- Bone Mineral Density (BMD): Measured by Dual-energy X-ray Absorptiometry (DXA) scan.
DXA Scan
- Primarily quantifies bone density, specifically at the hip and spine.
T-Score
- Represents bone density compared to a young, healthy adult (peak bone mass).
Bone Health Assessment Components
- Dietary intake
- Physical activity
- Medical history
- Family history
- Medications
- Lifestyle factors
Parathyroid Function Assessment
- Parathyroid hormone (PTH) levels are measured through laboratory tests.
Pharmacological Treatment Considerations
- Age
- Fracture history
- Bone mineral density (BMD)
- Underlying medical conditions
Osteoporosis Medication Mechanisms
- Antiresorptive agents: Inhibit bone resorption (breakdown).
- Anabolic agents: Stimulate bone formation.
Stimulates Osteoblastic Bone Formation
- Teriparatide (Forteo) is the primary medication for stimulating osteoblastic bone formation.
Most Cost-Effective Option
- Bisphosphonates are considered the most cost-effective option for osteoporosis treatment.
Oral Bisphosphonate Administration
- Weekly, monthly, or quarterly doses are typically administered.
Antiresorptive Medication Function
- Slows down bone loss by inhibiting bone resorption.
Pharmacological Treatment Age
- Considered for men and women aged 50 years and over.
T-Score Threshold for Pharmacological Treatment
- T-score of -2.5 or lower.
First-Line Osteoporosis Treatment
- Bisphosphonates are often the first-line agent due to cost-effectiveness.
Anabolic Drug Effect
- Increase bone mass by promoting bone formation.
