Study Notes

Osteoporosis and Bone Health

Osteoporosis is a condition characterized by weakened and brittle bones, increasing the risk of fractures.
Fractures in individuals with osteoporosis are more likely to occur in the wrist, spine, and hip.
Risk factors for osteoporosis can be classified as modifiable and non-modifiable.
Modifiable risk factors can be altered through changes in lifestyle and habits.
Non-modifiable risk factors cannot be changed.
Five simple steps for bone health and osteoporosis prevention include:
- Getting adequate daily intake of calcium and vitamin D.
- Engaging in regular physical activity, especially weight-bearing exercises.
- Avoiding smoking and excessive alcohol consumption.
- Regularly discussing bone health with a healthcare professional.
- Getting a bone density test and taking appropriate medications as recommended.
Vitamin D plays a crucial role in bone health, and deficiency can contribute to osteoporosis.
- Adequate vitamin D levels can help reduce fall risk by improving muscle function.
- Main dietary sources of vitamin D include:
  - Fortified milk
  - Fortified cereals
  - Cold saltwater fish
  - Calcium and vitamin/mineral supplements
Sunlight exposure is a natural source of vitamin D production in the skin.

Diagnosis and Assessment of Osteoporosis

Diagnosis of osteoporosis is primarily based on:
- Bone mineral density (BMD) measurement using a DEXA scan
- History of fragility fractures regardless of BMD.
BMD measurement with DEXA scan determines bone density at the hip and lumbar spine.
WHO criteria define osteoporosis based on T-score, which compares individual BMD to young adult values.
- T-score above -1.0 indicates normal bone density.
- T-score between -1.0 and -2.5 indicates low bone mass (osteopenia).
- T-score below -2.5 indicates osteoporosis.
Fracture prediction tools such as FRAX can estimate the 10-year risk of major osteoporotic fractures and hip fractures.

Treatment and Prevention Strategies

Treatment of osteoporosis aims to:
- Identify patients at risk of fractures.
- Reduce the incidence of fractures.
- Maintain quality of life.
Treatment options for osteoporosis include:
- Lifestyle modifications such as diet, exercise, and avoiding smoking and excessive alcohol.
- Medications such as bisphosphonates, calcitonin, parathyroid hormone (PTH), selective estrogen receptor modulators (SERMs), and estrogen/hormone therapy (ET/HT).
Bisphosphonates are a class of drugs that reduce bone resorption and increase bone density.
- They are FDA-approved for various indications, including prevention and treatment of osteoporosis in different populations.
Secondary fracture prevention is crucial after a fracture in people over 50, as it is a strong predictor of future fractures.
Fall prevention is essential, especially in elderly individuals, and includes measures such as:
- Improving home safety by removing tripping hazards.
- Engaging in physical therapy for balance and strength.
- Avoiding medications that affect alertness and balance.

Dual-energy X-ray Absorptiometry (DEXA) Scan

DEXA Scan measures bone mineral density at the hip and lumbar spine

Investigations for Possible Causes

Full blood count is used to check for Anemia
Bone profile checks for calcium and alkaline phosphate levels
Vitamin D levels are important to assess
Parathyroid hormone levels are important for bone turnover
Thyroid function tests are helpful as hyperthyroidism can lead to osteoporosis
Cortisol levels can be indicative of exogenous steroids

Plain Film X-Rays for Lumbar Spine

Used to assess for thoracic and lumbar vertebral fractures

Bone Density Test Recommendations

Women aged 65 and above, and men aged 70 and above should have a bone density test
Younger postmenopausal women and men ages 50-69 with clinical risk factors should be tested
Adults who have experienced a fracture after 50 should undergo a bone density test

Fracture Prediction Tools

The Fracture Risk Assessment Tool (FRAX) can calculate the 10-year probability of a major osteoporotic fracture and hip fracture
Treatment becomes cost-effective when the 10-year fracture risk is over 4%

WHO Criteria for Postmenopausal Osteoporosis

The T-score compares an individual's BMD with the mean value for young adults, expressed in standard deviation scores
Normal: T-score above -1.0
Low bone Mass (osteopenia): T-score between -1.0 and -2.5
Osteoporosis: T-score below -2.5

Vitamin D Intake

Vitamin D intake should be 800 - 1000 IU per day, with supplementation necessary for individuals aged 50 and above
Vitamin D intake can be obtained through sun exposure (10-15 minutes twice a week) but clothing, sunscreen and pollution reduce vitamin D production

Calcium Requirements for Individuals Over 50

Calcium intake should be at least 1,200 mg per day for individuals over 50

Calcium Supplements

Calcium carbonate needs stomach acid for absorption
Calcium citrate does not require stomach acid for absorption, making it more suitable for individuals with less stomach acid

Vitamin D's Role in Calcium Absorption

Vitamin D is essential for calcium absorption
Calcium and Vitamin D do not need to be consumed simultaneously to benefit from enhanced calcium absorption

FDA-Approved Medications for Osteoporosis

Bisphosphonates:
- Alendronate, Alendronate plus D (Fosamax, Fosamax Plus D)
- Rideosronate, Risedronate with Calcium (Actonel)
- Ibandronate (Boniva)
Calcitonin (Miacalcin, Fortical, Calcimar)
Parathyroid Hormone (PTH(1-34), Teriparatide) (Forteo)
Selective Estrogen Receptor Modulators (SERMs): Raloxifene (Evista)
Estrogen/Hormone Therapy (ET/HT): Premarin, Estrace, Prempro

Bisphosphonates - Antiresorptive Agents

FDA-approved for:
- prevention and treatment of osteoporosis in postmenopausal women
- treatment for increasing bone mass in men with osteoporosis
- treatment for glucocorticoid-induced osteoporosis
- treatment for Paget's Disease of bone
They reduce osteoclastic activity and bone resorption by binding bone mineral, being absorbed by osteoclasts, inducing apoptosis and suppressing resorption

Clinical Benefit of Bisphosphonates

3 years of bisphosphonate treatment in postmenopausal women with osteoporosis show relative risk reduction for fractures:
- Vertebrae: significant reduction
- Hip: significant reduction

Bisphosphonates - Administration

Must be taken at least 30 minutes before the first food, beverage, or medication of the day with water only.
Should only be taken upon waking up
Should be taken with a full glass of water
Patients should remain upright (walking, standing, or sitting) for at least 30 minutes (for monthly ibandronate, 60 minutes)
Should supplement with calcium and Vitamin D if dietary intake is inadequate

Bisphosphonates - Adverse Effects

Hypocalcemia
Hypophosphatemia
Musculoskeletal pain, crams (FDA warning)
Gastrointestinal:
- Abdominal pain
- Acid reflux
- Dyspepsia
- Esophageal ulcer
- Gastritis
Osteonecrosis of the jaw (IV bisphosphonates)
Visual disturbances (rare)

Zolendronic Acid (Reclast, Aclasta)

Approved for treatment of osteoporosis in postmenopausal women
Single 5 mg infusion given IV over 15 minutes, once yearly
Should still supplement with calcium and vitamin D
May be ideal for those with GI contraindications to oral formulations

Duration of Bisphosphonate Treatment

Bisphosphonates have a long residence time in bone
Long-term treatment raises questions about safety concerns
It is unclear if long-term treatment leads to a reservoir of the drug in bone, providing a continuing benefit after therapy is stopped

Recommended Duration of Bisphosphonate Treatment

5-10 years appears to be safe for most patients
Risk assessment is important for determining the length of treatment:
- Lower risk: drug holiday after 3-5 years
- Higher risk: drug holiday after 10 years
- Factors to consider for treatment length:
  - Adherence to medication
  - Drug pharmacokinetics
  - Underlying disorders that need to be addressed

Secondary Fracture Prevention

A fracture is a sentinel event
A fracture in a person over 50 is a significant risk factor for a future fracture
Many high-risk patients receive successful fracture treatment but do not receive subsequent medical assessments and treatment to prevent further fractures

Fall Prevention

Improve lighting in the home
Remove loose rugs
Install grab bars near bathtubs, toilets, and stairways
Consider a formal home safety evaluation
Incorporate physical therapy for core strength and balance
Avoid medication that can affect alertness and balance
Get an assistive device evaluation and training

Take Home Message

Clinicians should improve their ability to assess risk factors for osteoporosis and apply evidence-based screening recommendations to at-risk patients
Doctors should develop strategies to improve the treatment of patients with osteoporosis
Clinicians should utilize tools and information (patient education materials and system-based approaches) to facilitate improved assessment and care for patients with osteoporosis

Bone Health & Osteoporosis

Hip fractures can lead to nursing home placement for 1 in 5 people within a year
Some people with hip fractures may never walk again
The most common breaks in weak bones are in the wrist, spine, and hip
People start to lose bone mass after their mid-30s, with women losing bone mass faster after menopause
There are modifiable and non-modifiable risk factors for weak bones
Modifiable risk factors include diet, smoking, alcohol intake, physical activity, and medical conditions
Non-modifiable risk factors include family history of osteoporosis, age, small body build, and medical conditions

Osteoporosis Diagnosis

Osteoporosis is diagnosed by bone mineral density tests and/or a history of fragility fractures
Fragility fractures can happen from a fall from standing height or less
Signs of osteoporosis include loss of height, kyphosis (Dowager's hump), and back pain on palpation.

Patient Care Goals

The main goals of osteoporosis management are to identify patients at risk for fractures, reduce the incidence of fractures, and maintain quality of life

Osteoporosis Prevention

Five simple steps to bone health and osteoporosis prevention:
- Get your daily recommended amount of calcium and Vitamin D
- Be physically active everyday
- Avoid smoking and excessive alcohol
- Talk to your doctor about bone health
- Have a bone density test and consider taking medication if appropriate

Vitamin D

Vitamin D is manufactured in the skin from sunlight exposure
Dietary sources of vitamin D include fortified milk, fortified cereals, cold saltwater fish, and supplements
Vitamin D may reduce fracture risk through improved muscle function and reduced fall risk
Maintaining a 25-hydroxyvitamin D3 level greater than 40 ng/mL is beneficial for older adults
Vitamin D deficiency is prevalent in older adults and may require treatment with 50,000 IU of Vitamin D weekly for 6-8 weeks, followed by monthly therapy as needed

Osteoporosis Medications

FDA-approved medications for osteoporosis include:
- Bisphosphonates
- Calcitonin
- Parathyroid hormone (PTH)
- Selective estrogen receptor modulators (SERMs)
- Estrogen/Hormone therapy (ET/HT)

Bisphosphonates

Bisphosphonates are antiresorptive agents that reduce osteoclastic activity and bone resorption by binding bone mineral
Bisphosphonates can prevent and treat osteoporosis in postmenopausal women, men with osteoporosis, glucocorticoid-induced osteoporosis, and Paget’s disease of bone
These medications must be taken on an empty stomach with water and patients should remain upright for 30-60 minutes after taking them
Common side effects include hypocalcemia, hypophosphatemia, musculoskeletal pain, gastrointestinal issues, osteonecrosis of the jaw, and visual disturbances

Zolendronic Acid (Reclast®/Aclasta®)

A single 5mg infusion given IV once yearly
May be ideal for patients with gastrointestinal contraindications to oral bisphosphonate formulations

Bisphosphonate Treatment Duration

Bisphosphonates have a long residence time in bone
5-10 years of treatment appears safe for most patients
Drug holiday assessment should be considered after 3-5 years for lower risk patients and after 10 years for higher risk patients

Secondary Fracture Prevention

A fracture is a sentinel event indicating high risk of future fractures
High-risk patients often have fractures successfully treated, but do not receive further assessment and treatment to prevent future fractures

Fall Prevention

Strategies for fall prevention:
- Improve lighting
- Remove loose rugs
- Add grab bars near bathtubs, toilets, and stairways
- Formal home safety evaluation
- Physical therapy for core strength and balance
- Eliminate medications that can affect alertness and balance
- Assistive device evaluation and training
