What is the recommended dose of stress hydrocortisone (cortisol) for a pediatric patient with Systemic-Onset Juvenile Idiopathic Arthritis (SOJIA)?

Stress Dose Hydrocortisone in SOJIA

Critical Gap in Evidence

The provided evidence does not contain specific guidelines or recommendations for stress dose hydrocortisone in children with Systemic-Onset Juvenile Idiopathic Arthritis (SOJIA). The available literature focuses on chronic corticosteroid therapy for disease management rather than stress dosing protocols for patients on chronic glucocorticoid therapy.

Standard Stress Dosing Principles (General Pediatric Practice)

Since SOJIA-specific stress dosing guidelines are absent from the evidence, standard pediatric stress dosing protocols apply:

For Minor Stress (e.g., minor illness, dental procedures)

• Double the maintenance dose for the duration of illness, typically 2-3 days 1
• If the child is on chronic prednisone, convert to hydrocortisone equivalent (prednisone 1 mg = hydrocortisone 4 mg) and double that dose

For Moderate Stress (e.g., moderate illness, minor surgery)

• Hydrocortisone 25-50 mg/m²/day divided into 3-4 doses, or approximately 2-4 times the maintenance dose
• Continue until stress resolves, then taper back to maintenance

For Major Stress (e.g., major surgery, severe illness, trauma)

• Hydrocortisone 50-100 mg/m²/day divided every 6-8 hours IV/IM
• For severe stress: up to 100 mg/m² as initial bolus, followed by 100 mg/m²/day divided doses
• Taper to maintenance over 2-3 days as clinical condition improves

Context: Chronic Corticosteroid Use in SOJIA

Baseline Corticosteroid Therapy

• Corticosteroids are the mainstay of initial treatment in SOJIA, used in 100% of patients in reported cohorts 2
• High-dose alternate-day prednisone (1-5.8 mg/kg every other day, mean 3.2 mg/kg) has been used effectively for systemic features 3
• Daily prednisone may be used initially, with transition to alternate-day dosing once disease control is achieved 3

Adrenal Suppression Risk

• Any child on prednisone ≥20 mg/day (or equivalent) for >2 weeks or on chronic therapy for months is at risk for adrenal suppression 1
• These patients require stress dosing during physiologic stress to prevent adrenal crisis 1

Critical Clinical Pitfalls

Common Errors to Avoid

• Failing to provide stress dosing in SOJIA patients on chronic corticosteroids during intercurrent illness, surgery, or trauma
• Underestimating the degree of adrenal suppression in patients on alternate-day therapy—these patients still require stress coverage 3
• Abrupt discontinuation of corticosteroids without proper tapering, which can precipitate adrenal crisis 1

High-Risk Scenarios in SOJIA

• Macrophage activation syndrome (MAS) occurs in 11.9% of SOJIA patients and represents a life-threatening complication requiring aggressive corticosteroid therapy (often pulse methylprednisolone 30 mg/kg/day for 3 days) 2
• MAS with multiorgan insufficiency is the major mortality factor in SOJIA 2
• During MAS, stress dosing may need to be significantly higher than standard protocols

Monitoring Considerations

• Growth suppression is a concern with chronic corticosteroid therapy, though high-dose alternate-day regimens appear to minimize this effect 3
• Height standard deviation scores should be monitored regularly 3
• Other complications include cataracts, vertebral fractures, and possible avascular necrosis with prolonged therapy 3
• Bone mineral density testing should be considered for long-term corticosteroid therapy 4
