True or false:
- Oral glucocorticoids are absorbed in the Duodenum
False
Absorbed in the Jejunum
True or false
Concomitant food intake with oral glucocorticoids reduces the total amount abosorped
False

How long do you need to be taking steroids for before osteoporosis is an issue?
Rapid decline occurs in the first 3 months of usage
Rate of loss peaks at 6 months
True of False
Alternate morning treatment schedule for steroids reduces the risk of osteoporosis
False
It does NOT reduce the risk of Osteoporosis or cataracts
True or False
Trabecular bone is more prone to demineralisation than cortical bone with chronic steroid use.
True
Trabecular bone = axial skeleton, has a higher turnover rate than cortical bone (long bones), and is therefore more susceptible.
How often should you do DEXA scans on patients on long term steroids?
Baseline and every 1 -3 years
What are the benefits of alternate morning glucocorticoid therapy?
Decreases risk of:
- myopathy
- growth suppression
- HTN
- opportunistic infection
- electrolyte imbalance
Does NOT affect osteoporosis or cataract risk
Fluctuating BGLs in diabetes make this method unsuitable.
What are the key differences between steroid induced myopathy and myosiits?
Myositis
- weakness often WITH pain
- Elevated CK
- signs of muscle inflammation and oedema
- gets worse as steroids are weaned
Myopathy:
- often WITHOUT pain
- normal CK
- signs of atrophy WITHOUT inflammation
- gets better after 3 -4 weeks of dose reduction / cessation
