Efficacy and side-effect profile of tedizolid in the treatment of streptococcal toxic shock syndrome due to clindamycin-resistant Streptococcus pyogenes: A case report.

ABSTRACT

Oxazolidinones, such as tedizolid and linezolid, are bacteriostatic antibiotics that inhibit protein synthesis. Based on the findings from animal studies and their mechanism of action, these antibiotics are considered for managing toxic shock caused by clindamycin-resistant Group A Streptococcus (GAS; Streptococcus pyogenes). However, clinical reports on their usage in such cases are limited. Herein, we report a case of a 67-year-old woman with chronic myeloid leukemia who presented with fever, facial swelling, and myalgia. She was diagnosed with cellulitis and empirically treated with meropenem. Blood culture later revealed GAS, and she was diagnosed with streptococcal toxic shock syndrome. The antibiotic regimen was adjusted based on sensitivity results, with clindamycin initially replaced by linezolid and later switched to tedizolid owing to concerns about potential bone marrow suppression. Her condition improved, and she was discharged 15 days after admission. Therefore, tedizolid may be a safer option for managing toxic shock syndrome in patients with comorbidities that include thrombocytopenia.
