  • Title: [Cytokine storm in the pathogenesis of multiple organ dysfunction syndrome associated with surgical insults].
    Author: Aikawa N.
    Journal: Nihon Geka Gakkai Zasshi; 1996 Sep; 97(9):771-7. PubMed ID: 8940690.
    Abstract:
    Multiple organ dysfunction syndrome (MODS) is a critical condition developing in the patients under overwhelming surgical insults such as a major surgery, severe trauma, extensive burn, and systemic sepsis. The host response to those surgical insults is the main pathogenetic factor contributing to the development of shock and MODS seen in surgical patients. The proinflammatory cytokines, TNF-alpha (TNF) and interleukin-1 beta (IL-1), are known to play a pivotal role in the pathogenetic mechanisms of MODS. In response to surgical insults, macrophages produce and release TNF and IL-1 which subsequently induce the production of other cytokines (IL-6, IL-8, etc.) and other endogenous chemical mediators (growth factors, adhesion molecules, complement cleavage products, thrombin, eicosanoids, PAF, nitric oxides, oxygen-free radicals, granulocyte elastase, etc.) The resultant systemic inflammation may develop into shock and MODS when the primary insults are overwhelming (early MODS) or a second inflammatory insult such as sepsis triggers an exaggerated inflammation. In the patients suffering from MODS, a systemic release of various cytokines is not properly regulated, and the high blood levels of the proinflammatory cytokines induce an autodestructive generalized inflammatory reaction. This condition is termed "Cytokine Storm" by the author. In the cytokine storm, not only proinflammatory cytokines but also anti-inflammatory cytokines are elevated in the blood stream. With the recent understanding of the biological and pathological roles of cytokines and other mediators, a new therapeutic strategy has been developed. In addition to the reduction of the surgical insults, a variety of anti-cytokine therapy and anti-mediator therapy has been tested in an attempt to prevent or treat the life-threatening MODS.
