From the Guidelines
Treatment for a cytokine storm requires prompt medical intervention with immunomodulatory medications, and the most effective approach is to use tocilizumab 8mg/kg IV (maximum 800mg) as a single dose, in combination with corticosteroids such as dexamethasone 10mg IV every 6 hours, as recommended by the NCCN guidelines 1. The treatment approach should be tailored to the individual patient based on the severity of the cytokine storm, with Grade 1 patients receiving supportive care and Grade 2-4 patients receiving anti-IL-6 therapy with tocilizumab and corticosteroids. Some key points to consider in the treatment of cytokine storm include:
- Prompt and urgent intervention to prevent progression of the storm 1
- Use of tocilizumab 8mg/kg IV (maximum 800mg) as a single dose, with repeat doses as needed 1
- Use of corticosteroids such as dexamethasone 10mg IV every 6 hours 1
- Supportive care, including oxygen therapy, fluid management, and monitoring for complications 1
- Consideration of additional therapies, such as methylprednisolone, anakinra, siltuximab, and ruxolitinib, in refractory cases 1 The NCCN guidelines provide a comprehensive framework for the management of cytokine storm, and treatment should be initiated as soon as the storm is suspected, as indicated by rapidly worsening respiratory status, significantly elevated inflammatory markers, and multi-organ dysfunction 1.
From the FDA Drug Label
In a retrospective analysis of pooled outcome data from multiple clinical trials 45 patients were treated with tocilizumab 8 mg/kg (12 mg/kg for patients less than 30 kg) with or without additional high-dose corticosteroids for severe or life-threatening CAR T-cell-induced CRS A median of 1 dose of tocilizumab (range, 1-4 doses) was administered. No adverse reactions related to tocilizumab were reported [see Clinical Studies (14.10)].
Tocilizumab is used for the treatment of cytokine release syndrome (CRS), specifically CAR T-cell-induced CRS. The recommended dose is 8 mg/kg (12 mg/kg for patients less than 30 kg), with or without additional high-dose corticosteroids. The median number of doses administered is 1 dose (range, 1-4 doses). 2
From the Research
Treatment Options for Cytokine Storm
- Corticosteroids have been shown to be effective in reducing mortality in patients with cytokine storm, especially when used in combination with other treatments such as tocilizumab or anakinra 3
- Immunomodulatory therapies, including anti-IL-6 antibody (tocilizumab) and anti-IL-1 therapy (anakinra), have been used to treat cytokine storm, with some studies showing improved survival outcomes 3, 4
- The combination of corticosteroids and tocilizumab has been shown to be particularly effective in reducing hospital mortality in patients with COVID-19 cytokine storm 3
Pathogenesis and Diagnosis of Cytokine Storm
- Cytokine storm is a hyperinflammatory state characterized by the excessive production of cytokines, which can lead to multi-organ failure and death 5, 6
- The diagnosis of cytokine storm is a dynamic process, based on evolving or newly emerging findings during the clinical course, and may involve laboratory tests and imaging techniques 4
Management and Treatment Strategies
- Management of cytokine storm typically requires a multidisciplinary team approach, including the removal of abnormal inflammatory or immune system activation, preservation of vital organ function, treatment of the underlying disease, and provision of life supportive therapy 6
- Treatment strategies for cytokine storm may include the use of immunosuppressive and immunomodulatory drugs, such as corticosteroids, IL-6 blockers, or IL-1 blockers, to reduce the level of inappropriate systemic inflammation 4
