Omadacycline for a Carbapenem-Resistant -Associated Wound Infection.

Carbapenem-resistant Enterobacteriaceae (CRE) are problematic pathogens because infections caused by these organisms are associated with significant morbidity and mortality. These organisms often harbor multiple resistance mechanisms, which makes it difficult to treat their associated infections. Treatment typically consists of intravenous antibiotics that are selected based on the specific susceptibility pattern for the pathogen. Data on the use of oral antibiotics for the treatment of infections caused by CRE are sparse. In this case, a 62-year-old female presented with a chronic left leg wound infection. She previously underwent surgical debridement and skin grafting, which were unsuccessful. She was initially prescribed minocycline for the infection, but the wound got re-infected. At this time, the wound had significant surrounding erythema, drainage, and slough. A wound culture was obtained and demonstrated growth of carbapenem-resistant and methicillin-resistant . The patient was initiated on oral omadacycline, and she responded with resolution of the cellulitis and wound drainage. This case demonstrates that omadacycline may be beneficial as an oral medication for the treatment of complicated acute bacterial skin and skin structure infections caused by carbapenem-resistant .
