title: [Cytokines and nitric oxide in streptococcal toxic shock syndrome].
abstract: The plasma levels of endotoxin, tumor necrosis factor- alpha (TNF-alpha), interleukin -1 beta (IL-beta), IL-6, IL-8 and the nitrites and nitrates (NO2-/NO3-) as stable metabolites of nitric oxide (NO) were studied in the plasma of 2 patients with the streptococci toxic shock syndrome (STSS) associated to necrotizing fasciitis. A plasma profile of inflammatory mediators with high cytokine concentrations and NO2-/NO3- were observed with circulating endotoxin not being detected in plasma. The first patient died of fulminant refractory shock while the second survived following subacute evolution. The mediators profile, which was much higher in the first case, coincided with clinical severity. These data suggest that the cytokines and NO may have a role in the physiopathology of STSS and the severity of it is related to the levels of these mediators in the acute phase.
