addisons disease and adrenal insufficiency Flashcards
glucorticoids - systemic; what are the indiations
- treat allergic or ifnlammatory disorders e.g. asthma, anaphylaxis
2. supress autoimmune disease e.g. IBD, Arthritis
3. treat some cancers - as part of chemo or to reduce tumour associated swelling.
4. hormone replacement in adrenal insufficiency or hypopituitarism
MOA glucorticorticoids (systemic)
modify immune response
upregulate antinflammatory genes and downregulate proinflammatory fe genes.
metabolically - increase gluconeogenesis and have mineralocrticoid effect = na and h20 retention
SE of systemic glucorticoids aka steroids
- immunosurpession
- DM and osteoporosis
- increased catabolism = proximal muscle weakness, skin thinning, easy bruising, gastritis
- mood and behaviour change including insomnia
- HTN, hypok+, oedema
LTM = Adrenal atrophy = acute addisonian crisis
withdraw = fatigue, weight loss and arthralgia
who should you use systemic steroids carefully in
kids
those with infection
interactions of systemic steroids
- NSAIDs = combined = peptic ulcer and bleed.
- B3 agonists, theophylline, loop/thiazides = hypokalaemia enhanced
- cyp450i - Reduced action
- vaccines; steroids reduce effect.
name common systemic glucocorticoids
prednisolone
hydrocortisone
dexamethasone
most potent glucorticoids out of most common
dexamethasone.
what can you co prescribe with systemic steroids to reduce osteoporotic and GI effects
bisphosphonates, PPI
when should patients take systemic steroids
in mornign to match circadian rythym
