Q

Why is hydrocortisone unsuitable for disease suppression on a long term basis?

A

Fluid retention (due to relatively high mineralocorticoid activity)

Exception: adrenal replacement therapy in Adrenal insufficiency

Q

Prednisolone has predominantly (glucocorticoid/mineralocorticoid) activity with minimal (glucocorticoid/mineralocorticoid) effects

A
  1. Glucocorticoid
  2. Mineralocorticoid

Prednisolone is the corticosteroid most commonly used by mouth for long-term disease suppression

Q

Betamethasone and dexamethasone have very high (glucocorticoid/mineralocorticoid) activity in conjunction with insignificant (glucocorticoid/mineralocorticoid) activity.

A
  1. Glucocorticoid
  2. Mineralocorticoid

This makes them particularly suitable for high-dose therapy in conditions where fluid retention would be a disadvantage

Q

Some esters of betamethasone and beclomethasone exert a considerably more marked (oral/topical) effect than when given (orally/topically)

A
  1. Topical
  2. Orally

Use is made of this to obtain topical effects whilst minimising systemic side-effects

Q

If a patient using an inhaled corticosteroid get oral candidiasis and is treated with an anti-fungal oral suspension or oral gel, do they need to stop the corticosteroid therapy?

A

NO

An anti-fungal oral suspension or oral gel can be used to treat oral candidiasis without discontinuing corticosteroid therapy.

17
Q

What can be used to prevent mild paradoxical bronchospasm in a patient taking inhaled corticosteroids?

A

Short-acting beta-2 agonist inhaler before the corticosteroid

Moderate to severe paradoxical bronchospasm requires discontinuation and alternative therapy

18
Q

What are the common side effects of intranasal corticosteroids? (6)

A
  1. Altered smell sensation
  2. Epistaxis
  3. Headache
  4. Nasal complaints
  5. Taste altered
  6. Throat irritation
19
Q

What is a rare but serious uncommon side effect of intranasal corticosteroids?

A

Glaucoma

20
Q

What are the common side effects of topical corticosteroids?

A
  1. Skin reactions

2. Telangiectasia

21
Q

Do inhaled corticosteroids for asthma need o be stopped during pregnancy?

A

NO

Take as normal during pregnancy

22
Q

Should systemic corticosteroids be stopped during pregnancy?

A

Not usually

The benefit of treatment with corticosteroids during pregnancy outweighs the risk

Corticosteroid cover is required during labour

23
Q

What needs to be monitored in pregnant women taking systemic corticosteroids?

A

Fluid retention

24
Q

Do intranasal and systemic corticosteroids need to be stopped during breastfeeding?

A

NO

Benefits outweigh risks

Q

What needs to be monitored in children taking inhaled and systemic corticosteroids for a prolonged period? (2)

A

Height

Weight

26
Q

What needs to be monitored in children taking intranasal corticosteroids for a prolonged period? (1)

A

What are the indications for the use of deflazacort?

A
  1. Suppression of inflammatory and allergic disorders (oral(
    - Maintenance 3-18 mg daily
    - Acute: up to 120 mg daily

2. Mineralocorticoid

30
Q

In addition to the contraindications for all corticosteroids, what are the additional contraindications for the use of intravitreal dexamethasone? (5)

  5. Uncontrolled advanced glaucoma
31
Q

With intravitreal use of dexamethasone in adults, administration of which two drug classes requires caution?

A

Anticoagulants
Antiplatelets

Due to increased risk of haemorrhagic events

32
Q

Why do you need caution when prescribing intravitreal dexamethasone in patients taking anticoagulants or antiplatelet drugs?

A

Increased risk of haemorrhagic events

33
Q

What needs to be monitored in patients using intravitreal dexamethasone? (3)

A
  1. Intra-ocular pressure
  2. Signs of ocular infection
  3. In patients with posterior capsule tear or iris defect - monitor for implant migration
34

What are the indications for the use of fludrocortisone?

A
  1. Neuropathic postural hypotension
  2. Mineralocorticoid replacement in adrenocortical insufficiency
  3. Adrenocortical insufficiency resulting from septic shock (in combination with hydrocortisone)
35
Q

Hydrocortisone has (equal/unequal) glucocorticoid and mineralocorticoid activty

A

Equal

36

A
  1. BP
  2. Renal function (s-creatinine)

Increased incidence of scleroderma renal crisis

37
Q

What is the risk of using systemic prednisolone in patients with systemic sclerosis?

A

Increased incidence of scleroderma renal crisis

38
Q

As prednisolone crosses the placenta 88% of prednisolone is (?)

A

inactivated

39
Q

Prednisolone appears in small amounts in breast milk but maternal doses of up to (?) mg daily are unlikely to cause systemic effects in the infant

A

40 mg

Q

If a breastfeeding mother is taking more than 40 mg daily of prednisolone, what needs to be monitored for in the infant?
