Managing Steriods In Practise Flashcards
What can steroids be used for?
A) to suppress inflammatory process
B) steroid replacement where body doesn’t make enough
Give an example of steroids being used to suppress an inflammatory process
Oral prednisone for a chest infection
What’s the difference between glucocorticoid and mineralocorticoid activity?
Glucocorticoid- regulate carbohydrate, protein and fat metabolism. It is an anti-inflammatory immunosuppressant
Mineralocorticoid- regulates fluid and electrolyte levels
What drug would you use for a chest infection and why?
A glucocorticoid based drug as it has higher anti inflammatory action unlike mineralocorticoids
Give examples of conditions where steroid replacement therapy is needed
Addisons disease
Hypopituitarism (pituitary tumour)
Congenital adrenal hyperplasia
What does the adrenal cortex secrete?
Cortisol (glucocorticoid activity)
Aldosterone (mineralocorticoid)
What drug is used to replace cortisol in s Teri I’d replacement therapy?
Hydrocortisone
Tablets 15-40mg, 2-3 times a day
Larger dose given in morning
Eg. 10mg OM, 5mg LT, 5mg TT
What drug replaces aldosterone in steroid replacement therapy?
Fludrocortisone
Used when adrenal cortex is destroyed (addisons)
Also used in HPoT due to fluid retaining properties
50-300mcg daily in morning
What is the symptoms of adrenal insufficiency?
Hint acronym
A ppetite loss, unintentional weight loss, abdominal pain
D iscolouration of the skin
D ehydration
I ncreased thirst and polyuria
S alt cravings
O ligomenorrhoea
N o energy/ fatigue/ low mood
S ore/ weakness in muscles or joints
What is adrenal crisis?
The adrenal glands can’t cope with the extra corticosteroids needed hence life threatening symptoms can develop
Name 3 symptoms of adrenal crisis
Severe vomiting and diarrhoea—-> dehydration
Abdominal pain
Severe muscle weakness/ cramps
Severe drowsiness and fatigue
Pyrexia
Dizziness, low BP
Confusion
Limb and back pain
Delirium or loss of consciousness
How is adrenal crisis treated?
IV fluids or steroids
All steroid dependant patients need to be issued a steroid emergency card, what patients does this include?
Patients on LT prednisolone 5mg daily
Addisons
Hypothalamopituitary dysfunction
What happens to the dose of steroid if the patient is ill, injured or undergoes strenuous exercise?
- Generally, double the dose of hydrocortisone if fever or on antibiotics until recovered
- Vomiting is dangerous, patients may use emergency hydrocortisone injection & seek medical attention
- Up to double doses with extra fluid intake for strenuous events such as marathon
Why is hydrocortisone acetate not used in an emergency injection situation? What drugs are used instead?
It has a delayed onset so no good for emergency
Hydrocortisone sodium phosphate 100mg or hydrocortisone sodium succinate 100mg are used instead
What drug and usual dose is used for an inflammatory disease?
Oral prednisolone
30mg daily (6x5mg tabs, take all together in morning)
May be short course then stopped abruptly but can be long course
What are the desirable properties for glucocorticoid therapy?
High glucocorticoid activity
Relatively low mineralocorticoid activity
What are some side effects of long term steroid use?
Mood and behaviour changes eg. Confusion, irritability, delusions and suicidal thoughts
Increased susceptibility to infections
Suppression of normal adrenal function
What is classed as long term steroid treatment?
> 3 weeks
How does adrenal crisis occur?
Chronic deficiency conditions
Cessation of LT steroids/ rapid dose decrease
Infection, trauma, surgery etc
Name 3 side effects of short term steroid use and long term steroid use
ST- insomnia (take steroids in morning), mood disturbances and GI disturbances
LT- short course + increased susceptibility to infection, osteoporosis, adrenal suppression, cushingiod state, diabetes, skin changes (thinning, easy bruising), GI ulceration, hypokalaemia, growth retardation and fluid retention
A rare condition can occur when on corticosteroids where patients are encouraged to report and visual disturbances, what is the condition?
Chorioretinopathy
A retinal disorder
What are the contra indications of steroids?
Systemic infection (unless specific therapy given)
Avoid live virus vaccines
Name 3 cautions of steriod therapy
Children
Elderly
Chronic heart failure
Peptic ulcer
Epilepsy
Diabetes
Pregnancy
