title: [Severe infection from invasive beta-hemolytic streptococcus group A. Three cases of toxic shock observed in resuscitation].
abstract: Group A streptococci (GAS) may cause a variety of infections, some of which are severe and may be life-threatening. Patients affected by severe invasive GAS infections may develop, early in the course of the infection, a syndrome characterized by circulatory insufficiency with multiple organ failure: Streptococcal Toxic Shock-Like syndrome (Strep-TSLS). The presence of shock and organ failure differentiate it from other types of invasive GAS infections. Three cases patients presenting with the Strep-TSLS, over a period of 16 months in our multidisciplinary 10-bed ICU are described. The Strep-TSLS was of nosocomial origin in the first case, due to poststernotomy wound infection, caused from erysipela in the second patient, and associated to a puerperal sepsis in the third case, respectively. In this small series the primary sources of streptococcal infection associated with the syndrome are confirmed to be in soft tissues and skin. One patient died early after the admission to the ICU, whereas the other two patients completely recovered with appropriate antibiotic and supportive treatment although early diagnosis and radical operative debridement may have been conclusive in one case. All 3 observed cases fulfilled the consensus case definition of "certain case of Strep-TSLS", whose criteria have been recently revised.
