II. Mechanism: Natural Glucocorticoids (e.g. Cortisol)
- See Adrenal Gland Physiology
- Pathway
- Adrenal Cortex synthesizes and releases 21-carbon steroids in response to ACTH or Angiotensin II
- Glucocorticoids bind and activate cell surface Glucocorticoid receptors
- Triggers translocation of the Ligand-receptor complex to the nucleus
- In the nucleus, Glucocorticoid-responsive genes (e.g. lipocortins) are expressed
- Inhibits Phospholipase A2
- Prevents Arachidonic Acid release from phospholipid membranes
- Blocks synthesis of inflammatory Prostaglandins and Leukotrienes
- Inhibits inflammatory Cytokines
- Interleukin-1 (IL-1)
- Interleukin-6 (IL-6)
- Cytotoxic T-Lymphocytes
- Inhibits Phospholipase A2
- Glucocorticoids mobilize available energy sources (Glucose, fats, Amino Acids)
- Increases Serum Glucose
- Stimulates liver Gluconeogenesis and glycogenolysis
- Decreases Insulin receptor binding
- Increases serum Fatty Acids by promoting lipolysis of adipose Triglyceride stores
- Promotes truncal Obesity
- Increases blood Amino Acids by breaking down Proteins (outside liver)
- Increases Serum Glucose
- Glucocorticoid effects vary by tissue type
- Within the liver, anabolic (synthesis) effects predominate
- Within Muscle, skin, fat and connective tissue, catabolic (molecular breakdown, energy utilization) effects predominate
- Antiinflammatory activity
- Inhibit Histamine release
- Inhibits Lymphocyte production (but increases Neutrophil Count)
- Stabilizes MacrophageLysosomes and Antigen Processing
- Decreases Antibody production
- Gastrointestinal effects
- Increases gastric acid production and pepsin secretion
- Thins gastrointestinal mucosa
- Fluids and Electrolyte effects
- Increases Sodium retention
- Increases Potassium excretion
- Decreases Calcium absorption
- Increases clearance free water
- Metabolic Alkalosis
- Hematologic effects and Immune Effects
- Increases Red Blood Cell production (erythropoesis)
III. Mechanism: Synthetic Glucocorticoids (Corticosteroid analogs)
- As with natural Glucocorticoids, synthetic analogs have anti-inflammatory and immunomodulating activity
- Corticosteroid analogs are similar in structure and function to the natural 21-carbon steroids
IV. Precautions
- Systemic Glucocorticoids have significant adverse effects (see below)
- Systemic Glucocorticoids have many established indications with significant efficacy
- Asthma Exacerbation
- COPD Exacerbation
- Stress Dose Steroids
- Cancer Chemotherapy
- Peritonsillar Abscess
- Bells Palsy
- Acute Gout (in those unable to take NSAIDs)
- Extensive Allergic Contact Dermatitis (>20% of body surface area such as Rhus Dermatitis)
- However, many systemic steroid uses are NOT recommended (esp. for Upper Respiratory Infection) due to evidence against
- Not recommended in Acute Bronchitis (aside from acute COPD or Asthma Exacerbation)
- Not recommended in mild to moderate Acute Pharyngitis (aside from Peritonsillar Abscess)
- Not recommended in Acute Sinusitis
- Not recommended in Allergic Rhinitis (use Inhaled Corticosteroids instead)
- Not recommended in Carpal Tunnel Syndrome (use Carpal Tunnel Corticosteroid Injection instead)
- Controversial in Lumbar Radiculopathy (mixed study results)

- Tapering is generally not required for shorter steroid courses (and raises total steroid dose)
- Medrol dose pack (6 days of Methylprednisolone) offers no benefit and adds extra cost
- Instead prescribe one dose for 5 to 6 days (e.g. Prednisone 30 to 40 mg orally daily for 6 days)
- Cardiovascular disease risk
- Psychiatric effects
- Includes depression, anxiety, mania, Psychosis, Delirium and Insomnia
- Typically occurs in first week of therapy and resolves within a week of stopping the Corticosteroid
- Most have mild to moderate symptoms but may be severe in up to 5% of cases
- Symptoms may also occur (uncommonly) with high potency Topical Corticosteroids, Intranasal Corticosteroids
- Incidence of psychiatric effects increases with dose
- Occurs in 1% of patients on Prednisone 40 mg orally daily or less
- Occurs in 5% of patients on Prednisone 40 mg to 80 mg orally daily or less
- Occurs in 18% of patients on Prednisone 80 mg orally daily or more

XII. Management: Corticosteroid Tapering
- Background
- Indications
- Disease flare expected with short course (e.g. slow taper in Rhus Dermatitis)
- See specific conditions for these protocols
- Corticosteroid duration >3 weeks (or frequent steroid bursts)
- Risk of adrenal suppression if physiologic dose (>5 or 7.5 mg daily for >3 weeks) OR
- Frequent Corticosteroid bursts (3 or more in 6 months)
- Disease flare expected with short course (e.g. slow taper in Rhus Dermatitis)
- Protocol: Taper for Corticosteroid duration >3 weeks (or frequent steroid bursts)
- Reduce dose by 10-20% every 1 to 2 weeks (slower if on Corticosteroids for years)
- Consider ACTH Stimulation Test to confirm recovery of adrenal function before discontinuation
- Indications to slow taper
- Disease flare (e.g. COPD or PMR exacerbation)
- Adrenal Insufficiency signs of symptoms (e.g. Hypotension, myalgias, Fatigue)

XIII. Prevention: Corticosteroid complications
- See Corticosteroid Associated Osteoporosis
- See Steroid-Induced Hyperglycemia
- Avoid use when not truly indicated (e.g. Sinusitis, Acute Bronchitis, Pharyngitis)
- See Precautions above
- Even short course Corticosteroids (1 week) are associated with increased risk of Fractures, VTE and Sepsis

- Waljee (2017) BMJ 357:j1415 +PMID:28404617 [PubMed]
XIV. Management: Corticosteroids Pearls
-
Dexamethasone is ideal for single dose
- Dexamethasone has high oral Bioavailability (80%) with onset of action within 1-2 hours
- Duration of action approaches 60 hours
- No mineracorticoid activity
- However, Dexamethasone suspension is not tolerated well by children (due to taste)
- In Emergency Department, IV formulation (10 mg/ml) is given orally in flavor, Ibuprofen or Acetaminophen
- At home, Dexamethasone tablets may be given, and crushed in apple sauce
-
Prednisone and Prednisolone may be used interchangeably
- Similar in cost, Half-Life and activity (antiinflammatory, mineralcorticoid)
- Give Prednisone or Prednisolone once daily (instead of split dosing)
- Once daily dosing has sufficient duration of activity
- Split daily dosing (with a night dose) increases adverse effects (e.g. Insomnia)
- Limit split dosing to those patients who have gastrointestinal side effects on daily dosing amounts
