From the Research
Elevated Interleukin-18 (IL-18) levels at 300 are associated with a high risk of cytokine release syndrome (CRS), a potentially life-threatening condition that requires immediate medical attention. The management of CRS involves the use of glucocorticoids and cytokine inhibitors, such as tocilizumab, to reduce inflammation and prevent multi-organ failure 1, 2.
Pathophysiology of CRS
CRS is a phenomenon of immune hyperactivation that results in excessive cytokine secretion, including IL-18, which can lead to severe inflammation and tissue damage 3. The condition is often associated with the use of immune checkpoint inhibitors (ICIs) and other cancer immunotherapies 4, 5.
Clinical Presentation and Management
The clinical presentation of CRS can vary from mild to severe and may include symptoms such as fever, hypotension, hypoxia, and hepatic dysfunction 5, 2. Prompt recognition and treatment of CRS are critical to preventing long-term morbidity and mortality. The use of glucocorticoids and cytokine inhibitors, such as tocilizumab, is recommended for the management of severe CRS 1, 2.
Prognosis and Outcome
The prognosis and outcome of CRS depend on the severity of the condition and the promptness of treatment. Early recognition and treatment of CRS can significantly improve patient outcomes and reduce the risk of long-term morbidity and mortality 3, 2. However, delayed or inadequate treatment can lead to severe consequences, including multi-organ failure and death 1, 5.
