Steroids Flashcards
Do glucocorticoids mimic aldosterone or cortisol?
Cortisol
Do mineralocorticoids mimic aldosterone or cortisol?
Aldosterone
Name a corticosteroid with minimal glucocorticoid activity but very high mineralocorticoid activity?
Fludrocortisone
Name a corticosteroid with some glucocorticoid activity but high mineralocorticoid activity?
Hydrocortisone
Name a corticosteroid with predominant glucocorticoid activity and low mineralocorticoid activity
Prednisolone
Sick day rules for patients on long term steroids?
Double dose during intercurrent illness.
Abrupt withdrawal of steroids (in patients on long-term treatment) may precipitate what?
Addisonian crisis
In what circumstances does the BNF suggests a gradual withdrawal of systemic corticosteroids?
1) if the patient has received more than 40mg prednisolone daily for more than one week
2) if the patient has received more than 3 weeks of treatment
3) if the patient has recently received repeated courses
What are the 2 main mineralocorticoid side effects of corticosteroids?
1) fluid rentention
2) HTN
As mineralocorticoids mimic aldosterone.

What is hirsutism?
Hirsutism is excess hair growth on the body or face.
How can the risk of peptic ulcer disease and GI bleeding be reduced in those on long-term steroid treatment?
Prophylaxis with PPIs or H2-receptor antagonists.
How can the risk of hyperglycaemia & DM be reduced in those on long-term steroid treatment?
1) Monitor blood glucose levels regularly.
2) Initiate lifestyle modifications such as dietary changes and physical activity promotion.
3) If hyperglycaemia persists despite lifestyle interventions, consider adding oral hypoglycaemic agents or insulin therapy as per standard diabetes management guidelines.
