What are the first line treatment recommendations for patients with osteopenia?

First-Line Treatment Recommendations for Patients with Osteopenia

For patients with osteopenia, first-line treatment includes calcium and vitamin D supplementation, regular weight-bearing exercise, lifestyle modifications, and pharmacological therapy only for those with high fracture risk based on FRAX assessment. 1, 2

Risk Assessment

• Fracture risk should be calculated using the FRAX tool, which incorporates BMD and clinical risk factors to determine overall fracture risk 1
• Pharmacological treatment should be considered when FRAX calculation shows a 10-year risk of hip fracture ≥3% or 10-year risk of major osteoporotic fracture ≥20% 1, 3
• For patients on glucocorticoids, fracture risk should be adjusted by 1.15 for major osteoporotic fracture risk and 1.2 for hip fracture risk if prednisone dose is >7.5 mg/day 3

Non-Pharmacological Interventions (First-Line for All Patients)

• Calcium intake should be 1,000 mg daily for ages 19-50 and 1,200 mg daily for ages 51 and older 1, 2
• Vitamin D intake should be 600 IU daily for ages 19-70 and 800 IU daily for ages 71 and older, with a target serum level of ≥20 ng/mL 1, 2
• Regular weight-bearing and muscle-strengthening exercises help improve bone density 1, 2
• Balance training exercises such as tai chi can help reduce fall risk 1
• Smoking cessation and limiting alcohol consumption (1-2 drinks per day maximum) 1, 2
• Fall prevention strategies including vision and hearing checks, medication review, and home safety assessment 1

Pharmacological Treatment (For High-Risk Patients Only)

• Oral bisphosphonates (such as alendronate) are first-line pharmacological therapy due to safety, cost, and efficacy for patients with high fracture risk 1, 3
• Treatment should be strongly considered in patients with a BMD below a T-score of −2.0, particularly with additional risk factors 1
• Alternative therapies if oral bisphosphonates are not appropriate include:
  • IV bisphosphonates for patients who cannot tolerate oral formulations 1, 3
  • Denosumab for patients who cannot tolerate bisphosphonates 1, 2
  • Teriparatide for high-risk patients 1, 3
  • Selective estrogen receptor modulators (SERMs) 1

Special Populations

• Cancer treatments can accelerate bone loss, particularly those causing hypogonadism 1, 2
• For cancer survivors with osteopenia and additional risk factors, bisphosphonates or denosumab are preferred agents 2
• Liver transplant patients with osteopenia should perform regular weight-bearing exercise and receive calcium and vitamin D supplementation 4, 2
• Patients with chronic pancreatitis should receive basic preventive measures including adequate calcium/vitamin D intake and pancreatic enzyme supplementation if indicated 4

Monitoring

• Repeat DEXA every 2 years to monitor bone density and treatment response 1, 2
• For patients with osteopenia, the American College of Physicians recommends against bone density monitoring during the 5-year pharmacological treatment period 4
• Clinical fracture risk reassessment should be performed every 12 months for patients on glucocorticoids 3

Common Pitfalls to Avoid

• Poor adherence to preventive therapies is common; only 5-62% of patients on glucocorticoid therapy receive appropriate preventive therapies 1
• Failing to identify and treat secondary causes of osteopenia (vitamin D deficiency, hypogonadism, alcoholism, glucocorticoid exposure) 1
• Over-treating patients with low fracture risk with pharmacological therapy 4, 1
• Under-treating high-risk patients who would benefit from pharmacological intervention 5
• Most fractures occur in patients with osteopenia rather than osteoporosis due to the larger population size, making appropriate risk assessment crucial 5
