Vertebral osteomyelitis (VO) is an infection of the spine mostly caused by bacterial pathogens. The pathogenesis leading to destruction of intervertebral discs (IVD) and adjacent vertebral bodies (VB) is poorly described. We aimed to investigate the connection between infection, bone- and disc-metabolism in VO patients. Fourteen patients with VO (infection group) and 14 patients with incomplete burst fractures of the spine (fracture group as controls) were included prospectively. Demographic data, treatment details, laboratory infection markers, and patient-reported outcome were assessed. Tissue biopsies from affected IVDs and adjacent VBs were analyzed for mRNA-expression levels of 18 target genes including chemokines, adipokines and genes involved in bone-metabolism by RT-qPCR.Aim
