Carbapenemase-producing Klebsiella pneumoniae intra-abdominal infection successfully treated with ceftazidime/avibactam plus tigecycline

Ceftazidime/avibactam combines ceftazidime with a new beta-lactam that successfully that inhibits Amber Class A and D carbapenemases. We report a clinical case of a 61 year-old man with a carbapenemase-producing Klebsiella pneumoniae intra-abdominal infection after an elective abdominal hernia repair. The infection was successfully managed with multiple abdominal surgeries, drainage and combined antibiotic therapy with ceftazidime/avibactam plus tigecycline.
