How does toxic shock syndrome toxin work? Toxic shock syndrome toxin (TSST) is a superantigen with a size of 22 kDa produced by 5 to 25% of Staphylococcus aureus isolates. It causes toxic shock syndrome (TSS) by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumour necrosis factor.
What happens to the body during toxic shock syndrome? Toxic shock syndrome affects menstruating women, especially those who use super-absorbent tampons. The body responds with a sharp drop in blood pressure that deprives organs of oxygen and can lead to death.
What is the pathophysiology of toxic shock syndrome? Toxic shock syndrome (TSS) is caused from intoxication by one of several related Staphylococcus aureus exotoxins. The most commonly implicated toxins include TSS toxin type-1 (TSST-1) and Staphylococcal enterotoxin B. Almost all cases of menstrual TSS and half of all the nonmenstrual cases are caused by TSST-1.
How does the immune system respond to toxic shock syndrome? Toxic shock ensues when bacteria produce toxins known as superantigens and cause an inflammatory immune response, including the over-activation of cytokines.
