PurposeThis study aimed to investigate the trends in infectious spondylitis over the past two decades.MethodsWe included 157 cases, from 2000 to 2020, of infectious spondylitis. The cases were divided into two groups: 00 (cases during 2000-2009; 82 cases:) and 10 (cases during 2010-2020; 75 cases) groups. Patients' age, sex, causative organism, and localization were examined and compared between the two groups.ResultsThe proportions of women in the 00 and 10 groups were 30.5% and 38.7%, respectively, with no significant difference (P = 0.28). The average age was significantly higher in the 10 group (72.6 years) than in the 00 group (68.8 years; P < 0.01). A compromised host was the cause of infection in 52.4% and 36.0% of the patients in the 00 and 10 groups, respectively, showing a significant difference. The bacterial identification rates were 70.1% and 77.3% in the 00 and 10 groups, respectively (P < 0.01), and the genus Staphylococcus was the most common bacteria. The proportions of resistant bacteria such as methicillin-resistant Staphylococcus aureus in the 00 and 10 groups were 27.3% and 6.7%, respectively (P < 0.01). Conversely, infectious diseases caused by indigenous bacteria in the oral cavity and intestines were more common in the 10group (37.8%) than in the 00 group (13.0%), showing a significant difference (P < 0.01).ConclusionRecently, infections caused by indigenous bacteria in the oral cavity and intestines have increased more than those caused by resistant bacteria over the past two decade.© 2024.
