Severe illness associated with group A-hemolytic streptococcal infections.
The Wisconsin Division of Health (DOH) began surveillance for severe illnesses associated with group A beta-hemolytic streptococcus (GABS) infections in late 1989 to describe the current epidemiologic features and clinical spectrum of these infections in the state. Severe illness was defined by the isolation of GABS from the blood or by the development of one or more of the following in a patient infected with GABS: shock, extensive tissue injury, desquamating rash, disseminated intravascular coagulation, renal failure, adult respiratory distress syndrome, or death. Case reports involving 28 patients with severe GABS-related illnesses with onset from November 1989 through October 1990 were received by the DOH. The majority of the case-patients had sepsis (57%), cellulitis (50%) or both. Nine (32%) cases were fatal. Those who died were older than those who survived (median age 74 years v 43 years, p = 0.002) and were more likely to have clinical diagnoses that included pneumonia (relative risk [RR] 3.0, 95% confidence interval [CI] 1.2, 7.3) or necrotizing fasciitis/myositis (RR 3.7, 95% CI 1.5, 9.0). The median interval from illness onset to hospitalization was similar for fatal cases (1 day) and non-fatal cases (2 days), suggesting that early intervention after the appearance of clinical illness may not improve the outcome.
