Changing Pattern of Clinical Illness in Children with Group A Streptococcal Bacteremia
Objective: To test the hypothesis that bacteremia caused by group A streptococci (gas) has become more common and the presentation of the infection more severe in the Izaak Walton Killam Hospital for Children during the past decade.Design: Retrospective analysis by laboratory log and chart review.Setting: A pediatric teaching hospital providing primary and tertiary care.Results: There was no difference in the frequency of detection ofgasbacteremia between the two periods studied (1980 to 1988 and 1988 to 1991). However, severegasinfection with deep tissue invasion was more common in the last three-year period (77% versus 11%, P=0.01). Severity, as measured by length of hospital stay, was also greater in the recent group (17.9 days versus 3.3 days, P=0.03). A recent group of four children was identified with a unique clinical syndrome of rash, severe myalgias, hyperesthesia, and refusal to bear weight.Conclusion: The number of cases of severegasdisease has increased in the past several years, andgasinfection should be included in the differential diagnosis of seriously ill children,gasinfection must be managed aggressively with vigilance for additional deep tissue involvement, even while on appropriate antimicrobial therapy.
