MANAGEMENT OF OSTEOPOROSIS

Page 2: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

Goals

• 1. Identify appropriate patients to screen for osteoporosis

• 2. Describe how to interpret DXA scans appropriately

• 3. Compare and contrast the 2017 ACP Osteoporosis Treatment Guidelines with the

2019 Endocrine Society Osteoporosis Management Guidelines

• 4. Formulate pharmacologic treatment plans for patients with osteoporosis

Page 5: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

Who should be screened for osteoporosis?

https://www.uspreventiveservicestaskforce.org/Page/Document/RecommendationStatementFinal/osteoporosis-screening1

Screening Tools

1. SCORE

2. ORAI

3. OSIRIS

4. OST – Cutoff < 2

5. FRAX

Page 6: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

• FRAX was initially developed to assess 10 year fracture risk

for hip or major osteoporotic fractures in those who would be

left untreated

– Guides decision making process for treatment

• FRAX can also be used to assist in determining who would

benefit from screening of BMD

– T2DM increases risk of fracture

• Substitute history of RA with T2DM to reflect increased risk

• Should use country and population specific FRAX tool

Fracture Risk Assessment Tool (FRAX)

Who should be screened for osteoporosis?

• General screening recommendations are for older, healthy individuals

• DO NOT APPLY TO:

– Those with fragility fractures

– Secondary causes of osteoporosis: Metabolic bone disease, untreated hyperthyroidism,

hyperparathyroidism, multiple myeloma

– Certain medication usage: Long term steroid usage, aromatase inhibitors, GnRH agonists

NYU Winthrop Hospital8

Page 9: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

Why not start screening all patients at age 50?

• Fracture risk for any BMD is lower in younger post menopausal women

– 5-year probability of hip fracture < 1.0% until age 70–79 years

• Beginning treatment in younger women limits options for pharmacotherapy in their 70s

• Data on the risks and benefits of long term pharmacotherapy in younger patients (50–64

years) are unavailable

Page 10: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

• Dual energy X-ray absorptiometry

scan (DXA or DEXA) measures bone

mineral density (BMD) at the hip and

lumbar spine

– Gold Standard

• Clinical diagnosis is made with fragility

fracture at the spine, hip, wrist,

humerus, rib, or pelvis

– Fragility fractures - Spontaneous or minor

trauma

Alternate Methods

• Quantitative CT – Measures volumetric

bone density

– Clinical research

• Heel Ultrasound

– Not generally recommended as criteria for

osteoporosis and treatment threshold is not

well validated

• Peripheral DXA

– BMD measured via these techniques can

not be used interchangeably

How do we screen for and diagnose osteoporosis?

When to repeat screening with DXA?

• Baseline T scores should dictate how often DXA scan should be repeated

INTERPRETING DXA SCANS

Page 13: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

• BMD – Quantity not quality

• T Scores used in postmenopausal

women > 50

– T Score – BMD compared to average

healthy 30 year old adult

• Use Z Scores in women < 50

– Z Score - Age matched comparison

• T and Z Scores are not the whole

story

Interpreting DXA Scans

• Trabecular Bone Score

– Utilizes data obtained from DXA images

– Software calculates a TBS

– Provides information related to

microarchitecture

• Can potentially help identify individuals

who are at higher fracture risk despite

similar BMD

Page 18: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

Take Home Points on Screening with DXA

• All postmenopausal women > 65 should have a DXA scan

– Younger women (50-64) may be considered if fracture risk is high

• FRAX Score or OST can help identify higher risk patients

• Repeat screening determined by baseline DXA scan and risk factors

• When interpreting DXA scans review images

– BMD and T Scores may be deceiving

Who do we treat for osteoporosis?

NYU Winthrop Hospital20

Page 21: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

• Low Risk

– No previous fractures and

– T Score at spine and hip > -1.0 and

– 10 year FRAX < 3% at hip and < 20% MOF

• Moderate Risk

– No previous fractures and

– T Score at spine and hip > -2.5 or

– 10 year FRAX < 3% at hip and < 20% MOF

• High Risk

– Prior vertebral or hip fracture or

– T Score at spine or hip < -2.5 or

– 10 year FRAX ≥ 3% at hip and ≥ 20% MOF

• Very High Risk

– Multiple fractures and

– T Score at spine or hip < -2.5

How do we define risk?

TREATMENT OPTIONS

Page 26: MANAGEMENT OF OSTEOPOROSIS Osteoporosis 10_11_19.pdfWhy should we treat osteoporosis? • Estimated that 10 million Americans have osteoporosis – 44 million with low bone density

Lifestyle and Nutritional Management

• Calcium

– Women > 50 and Men > 70 – 1200 mg/d (Combined diet and supplements)

• Vitamin D

– Screen with Vitamin D level and ensure adequate level > 20 ng/dL

• Endocrine Society - > 30 ng/dL

– General recommendation is 800-1000 IU of vitamin D daily

• Weight Bearing and Balance Exercises

– Resistance and weight-bearing exercise can increase BMD

– Yoga and Thai Chi – Reduce fall risk

• Smoking cessation and reduction in alcohol consumption

Preferable to

obtain Calcium

and Vitamin D via

diet versus

supplementation

Romosozumab - Evenity

• Monoclonal antibody binds sclerostin

– Sclerostin is normally produced by osteocytes to

inhibit osteoblasts

• Monthly injection for 1 year

• Adverse Effects – Arthralgias, headaches,

hypersensitivity reactions, hypocalcemia

– Increases risk of MI, CVA and CV Death

• Should not be started in those who have had MI or CVA in

the past year

• ONJ defined as nonhealing wound in oral mucosa with exposed

bone lasting > 8 weeks

– Typically associated with dental procedures

• Estimated incidence range from 1 in 10,000 to 100,000

– Higher and more frequent dosing can increase the risk

– Long term bisphosphonate use risk can increase to 21 in 10,000

• ADA does not recommend stopping bisphosphonates for dental

procedures

• AAOMS recommends 2 month drug holiday in those on

bisphosphonates > 4 years

Take Home Points on Pharmacologic Treatment

• Most studies of pharmacologic agents are done with the background of calcium and

vitamin D

• Strong data for reducing fractures when treating with bisphosphonates, denosumab and

PTH related peptide analogues

• Benefits of treatment strongly outweigh the risks

– Utilize shared decision making

Monitoring BMD on Treatment How often should we be monitoring BMD in patients on

treatment?

• ACP – Do not monitor BMD with DXA while on 5 year

treatment period

– Reduction in fracture risk without changes in BMD

• Endocrine Society – DXA every 1-3 years

– BMD increase expected around 2 years

• Assess those who are not compliant with medication or treatment failure

– Retrospective studies showed that BMD monitoring was

associated with improved compliance

Pharmacotherapy with DenosumabPreserving BMD After

Denosumab

Newer evidence has demonstrated

that the increase in bone turnover

markers and decline in BMD is

associated with a potential “rebound”

effect or rapid return to baseline risk

resulting in increased risk of vertebral

fractures

May be avoided by starting a

bisphosphonate for 1 -2 years after

discontinuing bisphosphonate

Although denosumab is very effective in

increasing BMD and reducing fracture

risk, discontinuation or delay of therapy

results in rapid BMD loss and increased

vertebral fracture risk.

• At the time of guideline publication, these

agents were the only anabolic agents available

• Meta-analysis demonstrated 87% reduction in

vertebral fractures

– Reduction in hip fracture not statistically significant

but trended towards reduction

• Requires daily injections

– After 2 years, follow up with antiresorptive agent

Side Effects

• Hypercalcemia

• Osteosarcoma in rats – limit usage for 24 months in

humans – Black Box Warning

– Only 1 reported human case thus far

Summary

• Screen age appropriate post menopausal women for osteoporosis with DXA scan

– Repeat screening interval based upon initial T Scores

– Review DXA scan images

• Used shared decision making and evidence based guidelines to determine appropriate pharmacologic

treatment for patients

– Treatment should be individualized

– Generally bisphosphonates are first line agents with denosumab as a reasonable alternative

• Denosumab use should not be abruptly discontinued

• PTH related proteins (anabolic agents) should be used in very high risk individuals or those with multiple

vertebral fractures for up to 2 years

– Follow up treatment with an antiresorptive agent
