Clinical features of infectious spondylitis in patients with COVID-19

Objective. To  analyze the clinical features of the course of infectious spondylitis in patients with COVID-19.Material and Methods. A continuous retrospective study was performed with the analysis of medical records of 52 patients with infectious spondylitis who were treated in 2021–2022. The patients were divided into two groups: the study group (n = 24) – with a history of a new coronavirus infection; and the control group (n = 28) – without coronavirus infection.Results. The features of infectious spondylitis in patients with COVID-19 are the predominance of facultative anaerobic gram-negative flora in the focus of infection, a higher frequency of multilevel lesions, a tendency to increase the number of negative results of surgical treatment, and a chronic protracted course. At the same time, the course of infectious spondylitis associated with COVID-19 is accompanied by less destructive changes in the affected segment leading to a violation of the supporting function of the spine. Nevertheless, there is a statistically significant increase in the period of relief of the inflammatory process in the spine in these patients: 18.04 ± 3.84 weeks in the study group and 10.08 ± 2.34 weeks in the control group (Uemp < 240; p = 0.001).Conclusion. The secondary infectious lesion of the spine against the background of a new coronavirus infection is caused by gram-negative pathogens in the vast majority of cases, proceeds without severe bone destruction, with a tendency to a chronic protracted course. Surgical treatment of COVID-associated spondylitis is associated with a higher risk of postoperative complications.
