Thoracic spondylodiscitis secondary to Klebsiella oxytoca urosepsis-a case report.

Spondylodiscitis is an insidious and infectious pathology of the spinal column attributable to pathogenic micro-organisms and occurs in a variety of contexts. These micro-organisms can be inoculated surgically or can metastasise from distant sites of infection. Klebsiella species are important community-acquired and nosocomial pathogens but are uncommonly implicated in spinal infection. Klebsiella oxytoca is more obscure than its generic relative Klebsiella pneumoniae and has only five times previously been reported in spondylodiscitis. It possesses the ability to acquire inducible and recombinant antibiotic resistance, especially in the hospital setting. We describe the case of an elderly man with complex urology and this rare sequela due to incomplete treatment of a K. oxytoca urinary infection. He developed sepsis that recurred after incomplete antibiosis and seeded to his thoracic spine causing overt spondylodiscitis. The infection fulminated and his spinal lesion deteriorated into acute spinal cord compression with neurological compromise, requiring surgical decompression, fixation and long-term antibiotics. This is a sixth documented instance of a rare spinal bacterial infection. We describe the relevant microbiology and pathology, neurosurgical considerations, and general practice points for clinicians. Our report is a novel illustration of the potentially catastrophic consequences of inadequately treated urosepsis and is a stark reminder of the importance of antimicrobial stewardship.
