| Abstrakt: | Aim: To investigate how risk factors and reduced spinal mobility contribute to spinal infections arising from methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia, known for increased mortality and diagnostic difficulties, especially in patients with septic shock or coma. Methods: This retrospective study divided MSSA bacteremia patients into three groups: spinal infections (Group A, n = 14), non-spinal/implant infections (Group B, n = 24), and implant-related infections (Group C, n = 21). Analyses focused on demographics, medical history, laboratory inflammatory markers at antibiotic initiation, and spinal pathologies detected by CT. All results of the statistical analyses were significant at P < 0.05. We employed multinomial univariable logistic regression and contingency table analysis to assess risk factors across three groups. Subsequently, binomial multivariable logistic regression was used to compare Group A against Groups B and C, successfully identifying significant predictors of spinal infection. Results: A lower incidence of diabetes ( p = 0.029), higher C-reactive protein (CRP) levels at onset ( p = 0.014), and the presence of diffuse idiopathic skeletal hyperostosis (diffuse idiopathic skeletal hyperostosis (DISH); p = 0.022) were significantly associated with spinal infections in Group A. Furthermore, binomial analysis revealed DISH (Odds Ratio (OR) = 41.750; 95% Confidence Interval (CI) [1.86-939.0]; p = 0.019), absence of diabetes (OR = 1.20, CI [1.01-1.43], p = 0.038), elevated CRP (OR = 23.34, CI [1.13-483.4], p = 0.042), and a lower day 3/day 1 white blood cell (WBC) ratio (OR = 0.964, CI [0.93-1.00], p = 0.047) as risk factors when compared with other groups. Conclusion: Spinal infection patients with MSSA bacteremia are less likely to have diabetes and more likely to have higher initial CRP levels and DISH. Notably, DISH might be emerging as a distinctive risk factor for spinal infection, underscoring its potential as a marker for clinical awareness.
