What are the treatment options for male osteopenia?

Treatment Options for Male Osteopenia

Oral bisphosphonates (alendronate or risedronate) are the first-line pharmacologic treatment for men with osteopenia who are at high risk for fracture. 1

Risk Assessment and Diagnosis

• Use FRAX as the primary tool to assess fracture risk and determine treatment thresholds in men 1
• Use a female reference database for densitometric diagnosis of osteopenia/osteoporosis in men 1, 2
• Consider treatment for men with:
  • Age ≥70 years
  • Age 50-69 with risk factors (prior fracture, low body weight, smoking)
  • T-scores ≤-2.5
  • Prior fragility fractures 2

First-Line Treatment Approach

1. Lifestyle Modifications and Supplements:

   • Ensure vitamin D and calcium repletion in all men above 65 years 1
   • Recommend regular weight-bearing and resistance exercise 1
   • Advise a balanced diet with adequate protein intake 1
   • Calcium intake of 800-1200 mg daily and vitamin D supplementation (800 IU) for those with insufficiency 2

2. Pharmacologic Treatment:

   • First-line: Oral bisphosphonates (alendronate or risedronate) 1
     • Alendronate has demonstrated significant increases in lumbar spine BMD (5.3%) and femoral neck BMD (2.6%) after two years of treatment in men 3
   • Second-line: Denosumab or zoledronate for men who have contraindications to or experience adverse effects from bisphosphonates 1

Special Considerations

For Men at Very High Risk of Fracture

• Sequential therapy is recommended: start with a bone-forming agent followed by an anti-resorptive agent 1
• Abaloparatide can be considered as first-line treatment in this group 1, 2

For Men with Low Testosterone

• Assess serum total testosterone as part of pre-treatment evaluation 1
• Consider appropriate hormone replacement therapy in men with low levels of total or free serum testosterone 1
• Testosterone therapy has shown increases in lumbar spine BMD (6.8%) in hypogonadal men 4

Monitoring Treatment

• Use biochemical markers of bone turnover to assess adherence to anti-resorptive therapy 1
• Continue monitoring with serial dual-energy x-ray absorptiometry testing 5
• Be aware that up to 64% of men may be non-adherent to bisphosphonate therapy by 12 months 1

Common Pitfalls to Avoid

1. Underdiagnosis and undertreatment: Most men with osteopenia/osteoporosis are not diagnosed or treated 6
2. Inadequate calcium/vitamin D: Always ensure proper supplementation before and during treatment 2
3. Failure to identify secondary causes: Always assess for underlying conditions that may contribute to bone loss 2
4. Discontinuation without follow-up: Consider the risk of rebound bone loss when stopping treatment 1
5. Stigma: Address potential perception that osteoporosis is a "female condition" which may affect treatment adherence 2

Special Populations

Men on Androgen Deprivation Therapy

• These patients are at particularly high risk for bone loss and fractures 7
• Bisphosphonates (particularly zoledronic acid) not only prevent bone loss but can increase BMD during androgen deprivation therapy 7
• Regular BMD monitoring is essential in this population 6

Remember that the goal of treatment is to reduce fracture risk, improve quality of life, and decrease mortality associated with osteoporotic fractures. Early intervention in men with osteopenia who are at high risk for fracture can significantly improve outcomes.
