Streptococcal toxic shock syndrome (STSS) is caused by infection with a toxicogenic strain of Streptococcus pyogenes. Clinical manifestations may be those of a mild illness, characterized by malaise, fever, and muscle pain, to severe sepsis and multisystem organ failure. The syndrome may be associated with several invasive infections including necrotizing fasciitis. Treatment is primarily surgical debridement of infected tissue with supportive care, antibiotics, and hemodynamic monitoring. Intravenous immunoglobulin (IVIG) is reported to have beneficial effects in the management of STSS associated with necrotizing fasciitis. The agent was successful in conjunction with surgical excision and antibiotics in a patient with necrotizing fasciitis, toxic shock, and multisystem organ failure. On the basis of this experience and a thorough literature review, we concur that IVIG may be a useful adjunct in the treatment of STSS associated with necrotizing fasciitis.

Stevens-Johnson syndrome and toxic epidermal necrolysis (TEN) are mild-to-life-threatening adverse reactions that have been described after exposure to fluoroquinolones. No published reports, however, exist of exfoliative disease after treatment with levofloxacin. A 78-year-old woman with many medical problems, including chronic obstructive pulmonary disease, was treated with parenteral levofloxacin for community-acquired pneumonia. She was discharged with oral levofloxacin to complete an additional 3 days of treatment as an outpatient. Two days after completing this regimen, the patient developed a rash with blistering. The rash progressed to TEN in 7 days, and she was transferred to a burn treatment center. She was treated with fluid resuscitation, wound dressing, and antibiotics. Her condition improved, and she was discharged after 22 days. To our knowledge, this case is the first published report of levofloxacin-induced TEN.
