Update on Osteoporosis

Dr Terence O’Neill

• 3 million people have osteoporosis in the UK.

• 80 000 hip / 50 000 wrist / 120 000 vertebra

• £1.7 billion per annum.

Risk Assessment• Age

• Gender

• Prior Fracture (after age 50 years)

• Parental history of fracture

• Current Smoking

• Alcohol intake > 2 units / day

• Ever Corticosteroid use

• Secondary causes (e.g. RA)

NOGG - Treatment

• Alendronate

• If unable to take / intolerant

Risedronate / Ibandronate / Strontium

Raloxifene / Etidronate

What about NICE?

• After gestation of 6 years new technology appraisals published late 2008

• TA160 : Primary prevention

• TA 161 : Secondary prevention

NICE 161– Secondary Prevention

• Alendronate (ALN) treatment of choice in post-menopausal women if T-score < – 2.5

• Unable to take ALN – Risedronate (RIS) or etidronate (ETD)

• Unable to take RIS /ETD – Strontium / Raloxifene

* Age < 65 years + independent clinical risk factor for fracture + clinical risk of low BMD + T-score of < – 2.5

NICE 160– Primary Prevention

* Age 65-69 yrs + independent clinical risk factor for fracture + T-score of < – 2.5

* Age 75 +yrs + 2 or more risk factors – no need for BMD

NICE 160– Primary Prevention

* Age 70+ yrs + independent clinical risk factor for fracture OR clinical risk of low BMD + T-score of < – 2.5

NICE 160/161

• Difficult to use – copy of guidance to hand

• Restrictive : only few risk factors

• Unfair

• ALN first line therapy – Using NOGG many patients will be NICE compliant

Summary

• Osteoporosis is major health problem

• Effective therapies are available

• Challenge is targeting treatment – at risk

• NOGG / FRAX new approach to assessment of risk

• Use of NOGG should help target treatment to individuals at risk
