Toxic Shock Syndrome: An Unusual Organism

摘要

Streptococcal toxic shock syndrome is a rapidly fatal disease causing hypotension with multi organ dysfunction (MODS) early in the course of infection, which by definition is caused by Group A streptococcus (GAS). We describe a case of Toxic Shock like Syndrome (TSLS) in which the causative organism was not a GAS. A 71-year-old woman with hepatitis C and primary biliary cirrhosis had sudden onset of slurred speech and left arm and facial numbness. She had bilateral erythematous macular rash present on the flanks and legs. She was started on empiric antibiotics but her condition rapidly deteriorated 6 hours after admission. During this time, the development of multiple large reddish-pink areas of ecchymosis with bullae on her lower extremities, flanks, and groin were noted. She also developed multiorgan dysfunction (MODS) with renal dysfunction, coagulopathy and liver involvement. Patient expired before surgery could be performed and the time from presentation to the time of death was 16 hours. The blood and bullae fluid cultures grew Streptococcus dysgalactiae equisimilis. Streptococcus dysgalactiae equisimilis is a rare cause of TSLS which typically affects elderly or immunocompromised patients and only a few cases have been described in the literature. Our patient met criteria for TSLS which caused rapid shock and MODS. We review the literature of the cases describing the clinical characteristics of TSLS cause by non-GAS. Group G Streptococci is a rare but lethal cause of streptococcal toxic shock syndrome.
