Group A streptococcus bacteraemia: comparison of adults and children in a single medical centre.
Group A streptococcus (GAS) bacteraemia is often associated with soft-tissue infection, with significant morbidity and mortality. Little is known concerning the differences between adults and children with GAS bacteraemia. Records for 98 of 116 cases of GAS bacteraemia (60 adults and 38 children, aged 7 days to 96 years) occurring during a 10-year period (1993-2002) were located and reviewed. GAS bacteraemia comprised 0.6% of all bacteraemias in adults, compared to 3.3% in children (p < 0.001). The rate of adult GAS bacteraemia was two cases/1000 hospitalisations, compared to 13/1000 in children (p < 0.001). Seventy-six (78%) patients had concomitant tissue involvement, with skin or soft-tissue infection being the most common (62%). Fifty-three (88%) of 60 adults and five (13%) of 38 children had underlying conditions (p < 0.001). Twelve patients died, only one of whom was a child. Parameters associated with mortality were older age, lower temperature, hypotension, a need for surgical intervention, toxic shock syndrome, disseminated intravascular coagulation, thrombocytopenia, lymphopenia, hypocalcaemia, renal failure and acidosis (p < 0.05).
