Steroid Regimen for Interstitial Lung Disease (ILD) in Inpatient Setting

Initial Steroid Approach Based on ILD Type and Severity

  • The American Thoracic Society recommends pulse dose IV methylprednisolone (1000 mg daily for 3 days) followed by moderate-dose oral prednisone (up to 60 mg daily) for non-SSc SARD-ILD patients, with a slow taper over weeks to months 1, 2
  • For rapidly progressive ILD or acute respiratory failure, the American College of Chest Physicians recommends pulse dose IV methylprednisolone (1000 mg daily for 3 days) followed by high-dose oral prednisone (up to 60 mg daily) 1, 2, 4
  • The American College of Rheumatology strongly recommends against daily glucocorticoids as first-line treatment for SSc-ILD due to risk of scleroderma renal crisis 5, 3, 6
  • The European Respiratory Society does not recommend corticosteroid therapy for idiopathic pulmonary fibrosis (IPF) except in the context of acute exacerbation 7

Steroid-Sparing Agents

  • The American College of Rheumatology recommends mycophenolate mofetil as a first-line steroid-sparing agent for all SARD-ILD types 5, 3, 6, 8
  • Azathioprine is also recommended as a first-line steroid-sparing agent for SARD-ILD patients 5, 3
  • Rituximab is recommended for patients with inflammatory arthritis or myositis 5, 3
  • Cyclophosphamide is recommended for severe, rapidly progressive cases 5, 3, 4

Monitoring During Inpatient Treatment

  • The American Thoracic Society recommends daily assessment of respiratory status and oxygen requirements, as well as pulse oximetry at rest and with activity 1, 2
  • Serial pulmonary function tests are recommended as clinically indicated 1
  • Monitoring for steroid-related complications, such as hyperglycemia and hypertension, is recommended 10

Discharge Planning

  • The American College of Chest Physicians recommends tapering steroids to the lowest effective dose or off, and continuing steroid-sparing agents as maintenance therapy 1, 2, 5, 3
  • Close monitoring of pulmonary function tests every 3-6 months is recommended, especially in the first 1-2 years 1, 2
  • Antifibrotic therapy, such as nintedanib, may be considered for progressive fibrotic ILD phenotype 1, 2
