Toxic shock syndrome (TSS) is a rare but severe condition caused by bacterial toxins entering the bloodstream, commonly associated with Staphylococcus aureus and Streptococcus pyogenes. It can lead to multi-organ failure if not promptly treated.
5 Must Know Facts For Your Next Test
TSS is often linked to the use of superabsorbent tampons and post-surgical infections.
The toxins responsible for TSS act as superantigens, triggering an overwhelming immune response by activating a large number of T cells.
Symptoms of TSS include high fever, rash, low blood pressure, and multi-organ dysfunction.
Diagnosis of TSS involves clinical evaluation and laboratory tests to identify the presence of bacterial toxins.
Treatment includes administration of intravenous antibiotics and supportive care to manage symptoms.
