BACKGROUND: We aimed to describe the management and treatment of hip joint infections caused by multidrug-resistant Enterobacterales among patients with spinal cord injury (SCI).
METHODS: We included all hip joint infections associated with grade IV decubitus ulcers caused by extended-spectrum beta-lactamase producing Enterobacterales (ESBL-PE) and carbapenemase-producing Enterobacterales treated in a reference center for bone and joint infections over 9 years in a retrospective study.
RESULTS: Seventeen SCI patients with ischial pressure ulcers breaching the hip capsule (mean age 52 ± 15 years) were analyzed. In 16 patients, paraplegia was secondary to trauma and 1 was secondary to multiple sclerosis. Infections were mostly polymicrobial (n = 15; 88.2%), notably caused by Klebsiella pneumoniae (n = 10) and Staphylococcus aureus (n = 10). The carbapenemases identified were exclusively OXA-48-type (n = 3) including 2 isolates coexpressed with ESBL-PE within the same bacterial host. Multidrug-resistant Enterobacterales were commonly resistant to fluoroquinolones (n = 12; 70.6%). Most therapies were based on carbapenems (n = 10) and combination therapies (n = 13). Median duration of treatment was 45 (6-60) days. Of 17 cases of hip joint infections, 94.1% (n = 16) benefited from a femoral head and neck resection. Infection control was initially achieved in 58.8% (n = 10) of cases and up to 88.2% after revision surgeries, after a median follow-up of 3 (1-36) months.
CONCLUSIONS: Hip infections among SCI patients caused by multidrug-resistant Enterobacterales are often polymicrobial and fluoroquinolones-resistant infections caused by Klebsiella pneumoniae and S aureus, highlighting the need for expert centers with pluridisciplinary meetings associating experienced surgeons, clinical microbiologists, and infectious disease specialists.
