title: [Toxic shock syndrome in infection due to Streptococcus pyogenes].
abstract: Acute infections with group A beta-hemolytic streptococcus normally take a favourable course under therapy with penicillin. Only in a few cases has a completely different manifestation been described with multisystem failure similar to toxic shock syndrome induced by Staphylococcus aureus. We report on 4 patients (1990/91) who showed this manifestation in spite of immediate antibiotic therapy. In 3 patients the suspected portal of entry was the skin, in 1 patient it was unknown. Group A streptococci were grown from blood cultures from all 4 patients. Without an underlying immune deficiency all 4 patients (age 22, 24, 38 and 51) went into septic shock with high fever, hepatic and renal impairment, diarrhea, DIC and cerebral confusion. 2 patients died within a few days after developing acute respiratory distress syndrome and cerebral edema. All strains isolated from the patients were penicillin-sensitive, group A streptococci. 3 of them were M-type 1, which are known to be more invasive. The bacteremia by itself is not sufficient to explain all complications and the high mortality rate. It is probable that streptococcal toxins, such as pyrogenic exotoxin A, streptolysin O, or a new unknown one, play a decisive role.
