Cytokine release syndrome
From IDWiki
Background
Clinical Manifestations
- Fever, hypotension, tachypnea, tachycardia, headache, rash, dyspnea, hypoxemia
- With BiTE, most common after first dose or first few doses
- Time of onset is variable
- CAR-T: 2-3 days (range 1 to 14 days)
- Haploidentical HSCT: 1 to 3 days
- Bispecific antibodies: usually within 24-48 hours (range from minutes up to 9 days)
Prognosis
- Usually resolves within a few days to a few weeks
ASTCT CRS Grading1
| Parameter | Grade 1 | Grade 1 | Grade 3 | Grade 4 |
|---|---|---|---|---|
| Fever | ≥38ºC | ≥38ºC | ≥38ºC | ≥38ºC |
| with | ||||
| Hypotension | — | Not on vasopressors | One vasopressor ± vasopressin | Multiple vasopressors |
| and/or | ||||
| Hypoxia | — | Low-flow nasal cannula | High-flow nasal cannula, facemask, nonrebreather mask, Venturi mask | Positive-pressure ventilation (non-invasive or invasive) |
Management
- Broad-spectrum antibiotics empirically
- Grade 1: supportive care; if persistent fever for 72 hours consider tocilizumab
- Grade 2-4:
- Tocilizumab 8 mg/kg (max 800 mg), can be repeated q8h up to 4 doses; plus
- Dexamethasone 10 mg IV q12h (Grade 2) or q6h (Grades 3 & 4)
