Ceftazidime/avibactam for refractory bacteremia, vertebral diskitis/osteomyelitis with pre-vertebral abscess and bilateral psoas pyomyositis secondary to klebsiella pneumoniae carbapenemase-producing bacteria (KPC )

Abstract

  • A 36-year-old man was admitted to the intensive care unit due to diabetic ketoacidosis and pneumonia requiring mechanical ventilation. Three weeks after admission, he developed a refractory bacteremia with Klebsiella pneumoniae carbapenemase-producing bacteria (KPC). He remained febrile and with bacteremia for six weeks despite therapy with polymyxin B, carbapenems, and amikacin. Imaging studies looking for deep-seated infection revealed vertebral L1-L2 diskitis and osteomyelitis with pre-vertebral abscess and bilateral psoas pyomyositis that were not amenable for drainage. In view of the refractory infection and the activity against KPC described in the literature, we decided to switch the patient to ceftazidime/ avibactam. After six weeks of therapy, there was complete resolution of the infectious processes. We present an instance of clinical success with ceftazidime/avibactam for the treatment of refractory KPC bacteremia, vertebral diskitis and osteomyelitis with pre-vertebral abscess and bilateral psoas pyomyositis. This experience serves as reference to support treatment with ceftazidime/avibactam in similar complicated cases.
