1
Q

Description of osteoarthritis?

A

Damage to synovial joints leads to repair and structural change
o May occur through repeated excessive loading and stress of joint over time, or by injury

Progressive loss of cartilage leads to exposed bone being sclerotic and increased vascularity

Osteophytes form

Q

Description of osteoporosis? What are osteoporotic fractures?

A
  • Low bone mass and structural deterioration of bone tissue – leads to increase in bone fragility and susceptibility to fracture
  • Osteoporotic fracture = fragility fracture occurring as consequence of osteoporosis

Q

Definition of osteoporosis?

A

o Osteoporosis = Bone mineral density (BMD) of 2.5 SD below mean – measured by DEXA applied to femoral neck
o Osteopenia = BMD between -1 and -2.5 on DEXA

  • It may be primary (age related) or secondary (to conditions or drugs)

Q

Pathology of rheumatoid arthritis?

A
  • Affects typically small joints of hands and feet but can be at any synovial joint
  • Synovial fluid inflammation leads to thickening of lining and infiltration by inflammatory cells
  • Synovium proliferates over cartilage leaving ‘pannus’ – destroys cartilage and bone

Q

Diagnostic criteria of rheumatoid arthritis? When is diagnostic?

A

o People with >1 joint with definite swelling not explained by other disease

o Add total scores ≥6/10 is diagnostic

A – Joint Involvement (swelling or tenderness +/- imaging evidence)
	1 large joint = 0
	2-10 large joints = 1
	1-3 small joints = 2
	4-10 small joints = 3
	>10 joints (≥1 small) = 5
B – Serology
	Negative RF &amp; Anti-CCP = 0
	Low +ve RF/Anti-CCP = 2
	High +ve RF/Anti-CCP = 3
C – Acute phase reactants
	Normal CRP/ESR = 0
	Abnormal CRP or ESR = 1
D – Duration of symptoms
	<6 weeks = 0
	> 6 weeks = 1

o DMARD monotherapy within 3 months onset (1st-line)
 Methotrexate, leflunomide or sulfasalazine
 Consider hydroxychloroquine as alternative

2nd step
o Add another DMARD (oral methotrexate, leflunomide, sulfasalazine or hydroxychloroquine) when remission/low disease activity not achieved

o Add Biological Agents
 Sarilumab + Methotrexate (if severe DAS28)
 Others – adalimumab, etanerept, infliximab, certolizumab pegol, golimumab, tocilizumab, abatacept

4th Step
