Panelists discuss how recognizing and grading cytokine release syndrome (CRS) based on symptoms ranging from mild flulike effects to life-threatening conditions is essential for timely intervention, with early detection being key to managing CRS effectively and preventing progression to severe stages.

Summary for Physicians:

Cytokine Release Syndrome (CRS) Recognition and Intervention

  • CRS recognition:
  • Commonly occurs within 24 to 48 hours post infusion.

  • Symptoms include fever, chills, tachycardia, hypotension, dyspnea, and rash.
  • Grading CRS:
  • Grade 1: Mild fever and flulike symptoms, manageable with supportive care

  • Grade 2: Moderate symptoms (eg, hypotension), requires medical intervention (eg, fluids, antipyretics)

  • Grade 3: Severe symptoms (eg, hypoxia, multiorgan involvement), requires steroids and possibly tocilizumab

  • Grade 4: Life-threatening, requires emergency management and intensive care unit care
  • Intervention:
  • Grade 1: Symptom management (eg, acetaminophen, hydration)

  • Grade 2: Intravenous fluids, antipyretics, monitoring

  • Grade 3/4: Corticosteroids, tocilizumab (IL-6 inhibitor), and intensive monitoring

Challenges:

Early recognition is crucial for effective management and preventing progression to severe CRS.
