Cytokine storm syndrome is a diverse set of conditions that can result in a cytokine storm. Cytokine storm syndromes include familial hemophagocytic lymphohistiocytosis , Epstein-Barr virus–associated hemophagocytic lymphohistiocytosis, systemic or non-systemic juvenile idiopathic arthritis –associated macrophage activation syndrome , NLRC4 ...
In immunology, cytokine release syndrome (CRS) is a form of systemic inflammatory response syndrome (SIRS) that can be triggered by a variety of factors such as infections and certain drugs. [3] It refers to cytokine storm syndromes (CSS) [ 4 ] and occurs when large numbers of white blood cells are activated and release inflammatory cytokines ...
SIRS is a serious condition related to systemic inflammation, organ dysfunction, and organ failure. It is a subset of cytokine storm, in which there is abnormal regulation of various cytokines. [6] SIRS is also closely related to sepsis, in which patients satisfy criteria for SIRS and have a suspected or proven infection. [2] [3] [4] [7]
The infection tends to be mild, however, some suffer severe complications.
While optimal treatment of HLH is still being debated, current treatment regimes usually involve high dose corticosteroids, etoposide and cyclosporin. [citation needed] Intravenous immunoglobulin is also used. Methotrexate and vincristine have also been used. Other medications include cytokine targeted therapy. [citation needed]
Cytokine storms are also suspected to have been the main cause of death in the 1918 "Spanish Flu" pandemic. Deaths were weighted more heavily towards people with healthy immune systems, because of their ability to produce stronger immune responses, with dramatic increases in cytokine levels. Another example of cytokine storm is seen in acute ...
In many cases a trigger is identified, often a viral infection, or a medication. [2] There is uncontrolled activation and proliferation of macrophages, and T lymphocytes, with a marked increase in circulating cytokines, such as IFN-gamma, and GM-CSF. The underlying causative event is unclear, and is the subject of ongoing research.
Treatment for a disease varies greatly, requiring consideration of involvement, systemic characteristics, and MAS presence. Nonsteroidal anti-inflammatory medications can be safely administered for analgesic and antipyretic effects without altering initial diagnostic assessment results.
