Toxic shock syndrome (TSS) is an exotoxin-mediated illness caused by bacterial infection, most commonly group A streptococcus or Staphylococcus aureus.
Presenting signs and symptoms can be nonspecific, but the course of the disease is precipitous and toxicity occurs early, resulting in serious life-threatening disease and multiorgan system failure.
Early diagnosis and treatment is essential.
Streptococcal TSS can occur with infection at any site but is more commonly associated with an infected cutaneous site.
Staphylococcal TSS (menstrual or nonmenstrual) is associated with extended tampon use, postpartum infections, and other sites of infection with the organism.
Treatment includes supportive care in an intensive care unit, early empiric antibiotic treatment, and further culture-sensitive antibiotic treatment. Surgical debridement may be needed for deep-seated streptococcal infections.
Toxic shock syndrome (TSS) is an exotoxin-mediated illness caused by bacterial infection. Organisms commonly responsible include group A streptococcus (Streptococcus pyogenes), or methicillin-sensitive (MSSA) or methicillin-resistant (MRSA) Staphylococcus aureus.
Although the presenting signs and symptoms can be nonspecific (e.g., fever, chills, myalgias, headache), the course of the disease is precipitous, and shock and multiorgan system failure occur early in the course of the disease.
Staphylococcal TSS can be split into 2 groups: menstrual TSS, which occurs in women during menstruation with extended use of a single tampon or, historically, with highly absorbable tampons; and nonmenstrual TSS, which can result from a variety of staphylococcal postpartum vaginal and cesarean wound infections.
History and exam
Key diagnostic factors
- severe diffuse or localized pain in an extremity
- localized swelling or erythema
- diffuse, scarlatina-like erythematous rash
Other diagnostic factors
- acute mental status changes
- influenza-like symptoms
- muscular tenderness and weakness
- gastrointestinal symptoms
- features of myocarditis
- diabetes mellitus
- alcohol-use disorder
- minor trauma and injuries with bruising, hematoma formation, or muscle strain
- surgical procedures (e.g., vaginal delivery, breast reconstruction, cesarean section, hysterectomy, liposuction, bunionectomy)
- prolonged use (>6 hours) of single tampon
- use of highly absorbent tampons
- nonsteroidal anti-inflammatory drug (NSAID) use
- use of contraceptive sponges, diaphragms, and IUDs
- untreated strep throat
