Background: Considering that vertebral osteomyelitis (VO) can occur via various routes, it can be predicted that clinical characteristics may vary depending on the route of infection or risk factors of the disease. In this study, differences in clinical characteristics, causative pathogens, clinical features and prognosis were investigated in patients of native vertebral osteomyelitis with history of acupuncture.
Methods: This retrospective study was conducted at Kyung Hee University Hospital at Gangdong, Seoul. We extracted data of patients diagnosed with VO from May 2006 to February 2021 using an electronic database. Data on demography, clinical presentation, treatment, causative organisms and clinical outcomes were identified and compared according to the history of acupuncture.
Results: A total of 100 patients with VO were reviewed, among which 34 patients had a history of acupuncture prior to the diagnosis of VO. The frequency of Gram-positive cocci (GPC) was significantly higher in the acupuncture group than in the non-acupuncture group (p = 0.016). Abscess was observed more frequently in the acupuncture group than in the non-acupuncture group (p = 0.01). There was no difference in neurological sequelae and recurrence between the two groups. There was no difference in mortality between the two groups. (p = 0.098) CONCLUSION: This study suggests that confirming a history of acupuncture may help predict the pathogen or clinical characteristics of the disease. If the patient has a history of acupuncture, GPC can be considered as the causative organism, and the findings that abscesses and surgical treatment are more common may be helpful in evaluating patients.
