Toxic shock syndrome due to group A streptococcal pharyngitis and bacteremia in adults.

Bacteremia and/or toxic shock syndrome are rare complications of streptococcal pharyngitis in adults. This report describes a previously healthy young man with streptococcal toxic shock syndrome who presented with fatigue, high fever, and suspected extensive streptococcal tonsillopharyngitis. Treatment consisted of high-dose antibiotics followed by therapy for consumptive coagulopathy, acute renal failure, and toxic shock syndrome. An attempt at hemodialysis and hemodiafiltration was ineffective, and the patient died within 24 h of admission. The autopsy findings were compatible with the clinical diagnosis. The invasive group A streptococci isolated from the pharyngeal swab and blood cultures were identified as M1 and T1 types with pyrogenic exotoxin genes A and B. This was a definitive case of streptococcal toxic shock syndrome complicated with multiorgan failure and fatal outcome. The benefits of intravenous immunoglobulins, surgical intervention, or clindamycin for improving survival remain to be evaluated.
