Osteoporosis Update: Advances in Treatment Suzanne Jan de Beur, MD Johns Hopkins University School of Medicine 8/21/2021 1
Slide 2-

Incidentally Discovered Vertebral Fracture A 70 year old female smoker being evaluated for a cough presents for discussion of recently order chest xray. You explain that the CXR shows no infiltrates or masses in the lung tissue itself but there is an incidental vertebral compression fracture at T12 noted. 8/21/2021 2

What do you ask next? 8/21/2021 3
Slide 4-

Delving Deeper Upon further discussion you ascertain: She remembers a 2 month history of significant back pain that spontaneously resolved after a fall from standing height while working in the yard 3 years ago shortly after she retired She is 2 inches shorter than her peak adult height No previous fractures 8/21/2021 4
Slide 5-

Delving Deeper: Secondary Causes No current or past history use of steroids Alcohol intake is one glass of wine daily 50 pack year history of smoking Menopause age 52 No weight gain or weight loss No diarrhea or malabsorption symptoms Physically active and rarely falls Normal renal function with no kidney stones 8/21/2021 5

Summary Fragility fracture is skeletal failure and must prompt evaluation and treatment Denosumab use for up to 10 years is safe and effective New data suggest that a limited course of Zoledronic acid even in those with osteopenia reduces fracture There are a variety of new treatment options for osteoporosis that can allow tailoring therapy to the individual characteristics “Medication Holiday” applies only to Bisphosphonates other agents including denosumab must be continued or followed by other therapy 8/21/2021 67

WHO, Guidelines for Preclinical Evaluation and Clinical Trials in Osteoporosis, 1998. T-Score World Health Organization (WHO) Osteoporosis Definition SD
Slide 74-

Previous Guidelines Initiate pharmacologic treatment in: Those with a T score <-2.5 at the hip, spine or femoral neck Those with osteopenia and a FRAX 10 yr probability >20% of major osteoporotic fracture or >3% of hip fracture 8/21/2021 74
Slide 75-

What is FRAX®? The FRAX® tool has been developed by WHO to evaluate fracture risk of patients. It is based on individual patient models that integrate the risks associated with clinical risk factors as well as bone mineral density (BMD) at the femoral neck. The FRAX® models have been developed from studying population-based cohorts from Europe, North America, Asia and Australia. The FRAX® algorithms give the 10-year probability of fracture. The output is a 10-year probability of hip fracture and the 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture).
