Transcript of Osteoporosis UnAd
Osteoporosis is often asymptomatic until a
fracture occurs; these can occur with minimal or
no trauma.1 Risk factors for osteoporosis include
female gender,older age, low calcium intake,
vitamin D deficiency,BMI < 21 kg/m2, steroid use,
excessive alcohol intake, smoking,and inadequate
exercise.2-4
Keeping bones from breaking
Osteoporosis is common in elderly patients. It can cause preventable
fractures leading to hospitalization, loss of mobility, nursing home admission,
and increased mortality.
A few simple interventions can make a big difference.

Several simple dietary and lifestyle interventions can help maintain BMD and/or reduce therisk of falls and fractures, even for patients with normal bone mass.
Test bone mineral densityTest bone mineral density (BMD) with dual-energy x-ray absorptiometry (DXA,DEXA) in
the following groups:2, 4
• women ≥ 65 and men ≥ 70 • younger peri- and post-menopausal women and men with risk factors such as low body
weight (BMI < 21 kg/m2) or prior low-trauma fracture• anyone with other risk factors for low bone mass such as rheumatoid arthritis or systemic
steroid use for ≥ 3 months• anyone with prior fracture after age 50 • postmenopausal women discontinuing estrogen
2 3
Make a few simple assessments
BMD measurements are reported as T-scores. Use the lowest (most negative) of the hip,femoral neck, and lumbar spine scores for diagnosis.4 A patient who has had a low/no traumafracture should be considered to have osteoporosis regardless of BMD.5

Table 1. T-scores and diagnosis
Estimate fracture risk A WHO fracture risk algorithm (FRAX) can be used to calculate the 10-year risk of hip and
other major osteoporotic fractures.2 The US-adapted algorithm is available at http://www.shef.ac.uk/FRAX/ for Hispanic, Black, Caucasian, and Asian men and women. The score isbased upon age, gender, weight, height, BMD, and clinical risk factors including priorfracture, family history of hip fracture, use of oral glucocorticoids (at a daily dose ≥ 5 mg ofprednisone or equivalent for ≥ 3 months), smoking, excessive alcohol use (3 or more drinksper day), and rheumatoid arthritis. The risk calculator can help determine whether or not tostart drug therapy (see Figure 1). Hardcopy charts of fracture risk are available at the abovewebsite and examples of these charts are provided as an appendix to the accompanyingevidence document.

• Vitamin D deficiency is common.2, 6, 7 Consider checking serum 25-OH vitamin D, especially in older patients and those with low bone density.4
• Measure serum calcium, and work up if abnormal; a 24-hour urine calcium ≤ 50 mg suggests either insufficient calcium intake or poor absorption.4
• If a specific cause of osteoporosis is suspected, other relevant studies may include thyroid function tests, testosterone levels in men, antibody testing for celiac disease, and a serum parathyroid hormone level.

• Daily intake of at least 1,200 mg of elemental calcium per day for people 50 years and older, including supplements if dietary intake is inadequate.2
• An easy-to-use dietary calcium calculator is available at http://www.myoptum health.com/portal/ManageMyHealth/Calcium+Calculator• For optimal absorption, a single dose of calcium supplement should contain no more than 500 mg of elemental calcium, so divided doses may be needed.1,4
• Calcium carbonate should be taken with meals. Calcium citrate is more expensive, but does not need to be taken with meals; it is preferred in patients on acid-suppressive therapies.1,4
• Daily intake of 800 - 1,000 international units (IU) per day for people ≥ 50.2
• Some older patients may need at least 2,000 IU per day to maintain adequate 25(OH)D levels.2
• One strategy for correcting vitamin D deficiency is 50,000 IU weekly of oral vitamin D2 for 8 weeks, followed by a maintenance dosage of 50,000 IU every 2-4 weeks or 1,000 IU of oral vitamin D3 once daily.1
• Re-test serum 25(OH)D levels after at least 12 weeks of supplementation, because steady state of 25(OH)D is not achieved until that time.4
• Weight-bearing and muscle-strengthening exercises reduce the risk of falls and increase bone density.8
• Review prescriptions that may cause impaired balance/mobility, sedation, or confusion; check and correct vision and hearing problems; improve home safety.
• Smoking and excessive alcohol consumption (over 3 drinks per day) increase the risk of osteoporosis.10 Yet another reason to quit smoking.

Comparative effectivenessNo head-to-head clinical trials have studied bisphosphonates in relation to each other
or to other drug classes for anti-fracture efficacy,4 making comparisons difficult.11, 12 A largeobservational study, controlling for patient characteristics, found that patient takingbisphosphonates had lower fracture risks than those taking raloxifene or calcitonin.13 The most affordable and tolerable bisphosphonate should be the first-line treatment for fractureprevention.
When a prescription is needed
Bisphosphonates include alendronate (generics, Fosamax, Fosamax plus D), ibandronate(Boniva), risedronate (Actonel, Actonel with calcium), and zoledronate (Reclast).
Consider an osteoporosis drug for postmenopausal women and men ≥ 50 who have:
• an osteoporotic hip or vertebral fracture; or• a T-score equal to or more negative than -2.5 at any site ; or • low BMD (T-score between -1.0 and -2.5) as well as: – a 10-year risk of a hip fracture ≥ 3%, based on FRAX, or – a 10-year risk of any major osteoporosis-related fracture (spine, hip, shoulder, or wrist) ≥ 20%, based on FRAX
Postmenopausal women

• Reduces the risk of vertebral and non-vertebral fractures in postmenopausal women with a prior vertebral fracture. • Duration of therapy (up to 2 years only) and high cost may limit its usefulness. • Also reduces the risk of vertebral fractures in men, as well as steroid-induced osteoporosis.
• Reduces the risk of vertebral fractures in postmenopausal women with osteoporosis..
• Reduces the risk of vertebral fractures in postmenopausal women with osteoporosis.
• Reduces the risk of risk of vertebral, non-vertebral, and hip fractures in postmenopausal women with osteoporosis.
• Although HT (estrogens with or without progestogens) is FDA-approved for the prevention of osteoporosis in postmenopausal women, if this is the sole aim of treatment, other drugs should be used because of the cancer and cardiovascular side effects of HT.2 • Long term HT use is not indicated for the treatment of osteoporosis,10 and its BMD benefits are lost soon after discontinuation.4

Efficacy
Table 4. The evidence for efficacy
ONJ is a condition of localized “bone death” that has been reported rarely in patients takingoral bisphosphonates, and can be difficult to treat. After widely publicized reports of ONJ, manypatients stopped taking their bisphosphonates, and many physicians became concerned aboutwhether to continue prescribing them. However, the risk of bisphosphonate-related ONJ is verylow with oral bisphosphonates used to treat osteoporosis; dental surgery increases the risk. Thecondition is more commonly seen in cancer patients given intravenous bisphosphonates.16
Consider discontinuing an oral bisphosphonate for at least 3 months prior to oral surgery inpatients who have taken the drug for >3 years, or in those who have taken it for <3 years and areon corticosteroids. The drug should not be restarted until bone has fully healed.16

• Assess adverse effects and compliance (which is often poor).• Encourage adequate calcium and vitamin D intake, exercise, falls prevention, smoking
cessation, and avoidance of excessive alcohol use.• Re-check bone mineral density 2 years after starting a drug, and every 2 years thereafter.
More frequent testing may be warranted for some patients, such as those taking high-dosesteroids.
• Reassess the need for continuing use of a bisphosphonate after 5 years unless the T-scoreremains lower than – 2.5.
Adherence to regimens of medications for osteoporosis (including calcium and vitamin D)is often quite low.5, 11, 14 One study found that women with high prescription drug compliancehad a 16% lower fracture rate than those with low compliance.15
Strategies to improve adherence include:5, 11
• educate patients about the importance of the medication and the need to take itconsistently;
• consider a weekly-dosed oral bisphosphonate – it may improve adherence compared withdaily dosing in some patients;
• choose the most affordable and effective option;• provide written instructions on dosing and duration of therapy;• encourage a reminder system or use of an adherence aid such as a pill box; and• ask about adverse effects (such as gastrointestinal side effects with bisphosphonates, or
hot flashes with raloxifene) and consider an alternative if indicated.
Monitor response to therapy
Cost may be a barrier to adherence. Generic alendronate is now available, makingbisphosphonate therapy more affordable. Injectable drugs may incur an additional up-frontexpense.5 The costs of a 30-day supply of typical doses of these medications are listed below.
