CRS usually occurs between 1 and 14 days after the CAR T-cell infusion and can last up to ten days. Delayed onset CRS can occur but rarely presents beyond this period. The severity of CRS is dependent on the type of CAR T product infused, disease characteristics and the grading system that has been used.

CRS is an acute systemic inflammatory response, characterised by fever and in severe events can lead to multiple organ dysfunction. Severity of CRS ranges from mild to life-threatening, and when severe, is considered an oncological emergency.

2017年11月27日 · Grade 1: fever with or without constitutional symptoms. Grade 2: hypotension responding to fluids; hypoxia responding to <40% O 2. Grade 3: hypotension managed with one pressor; hypoxia requiring ≥40% O 2. Grade 4: life-threatening consequences; urgent …

Organ toxicities associated with CRS may be graded according to CTCAE v5.0 but they do not influence CRS grading. * Fever is defined as temperature ≥38°C not attributable to any other cause. In patients who have CRS then receive antipyretic or anticytokine therapy such as tocilizumab or steroids, fever is no longer required to grade ...

CRS is an exaggerated response of the innate immune system, which activates the adaptive immune system causing a further activation of innate immune cells and release of more cytokines. Antibody mediated reaction due to immunological memory of B-cells to the offending medication. Generally driven by immunoglobulin E (IgE) but can

CRS is a rare but serious condition that represents a supraphysiologic response to immunotherapy with a resultant overproduction of cytokines from immune effector cells. High tumor burden and profound suppression of hematopoiesis increase the risk of CRS [7,8].

Cytokine-release syndrome (CRS), the most commonly observed toxicity, can range in severity from low-grade constitutional symptoms to a high-grade syndrome associated with life-threatening multiorgan dysfunction; rarely, severe CRS can evolve into fulminant haemophagocytic lymphohistiocytosis (HLH).

Excessive and rapid release of cytokines into the blood stream can result in cytokine release syndrome (CRS). CRS is an acute systemic inflammatory response, characterised by fever and in severe events can lead to multiple organ dysfunction.

2022年11月15日 · CAR T cell therapy can be complicated by cytokine release syndrome (CRS), a syndrome characterized by systemic inflammatory response, in which interleukin (IL) -6 plays a central role. Tocilizumab is a monoclonal antibody targeting the IL-6 receptor and is recommended for treatment of CRS.

2019年5月16日 · Fever ≥38°C as an early sign of CRS occurred with a median of 2 ± 0.3 days (range, 0-4 days) after infusion of CAR T cells in low-grade neurotoxicity patients. In this subcohort, CRS consistently preceded the onset of neurologic symptoms, and the median time between first fever and first neurologic symptoms was 3 ± 1.5 days (range, 1-19 days).
