CLINICAL MANIFESTATIONS:
Toxic shock syndrome (TSS) may be caused by toxin-producing Staphylococcus aureus or Streptococcus pyogenes (group A streptococci). Both organisms cause an acute illness characterized by fever, rapid-onset hypotension, rapidly accelerated renal failure, and multisystem organ involvement (see Tables 3.62, p 625, and 3.63, p 626). Profuse watery diarrhea, vomiting, generalized erythroderma, conjunctival injection, and severe myalgias commonly are present with S aureus-mediated TSS but are less common with S pyogenes-mediated TSS. Evidence of local soft tissue infection (eg, cellulitis, abscess, myositis, or necrotizing fasciitis) associated with severe increasing pain is common with S pyogenes-mediated TSS but not with S aureus-mediated TSS. The presence of a foreign body at the site of infection is common with S aureus-mediated TSS, but not with S pyogenes-mediated TSS. Both forms of TSS may occur without a readily identifiable focus of infection. Both forms of TSS also may be associated with invasive infections, such as pneumonia, osteomyelitis, bacteremia, pyarthrosis, or endocarditis. Patients with S aureus-mediated TSS, especially menses associated, are at risk of a recurrent episode of TSS. Recurrent episodes have not been reported for S pyogenes-mediated TSS. Toxic shock can be confused with many infectious and noninfectious causes of fever with mucocutaneous manifestations.

ETIOLOGY:
Staphylococcus aureus-mediated TSS usually is caused by strains producing toxic-shock syndrome toxin-1 (TSST-1). Most of these strains also produce . . . [Go to Full Text]
