The mean age was 61.0 (SD: 13.8) years, and 80 (18.9%) received at least one advanced therapy. Sixteen (20%) patients developed serious infections, with a total of 23 serious infection episodes reported. The overall incidence rate of serious infections was 3.75 per 100 patient-years. Respiratory infections were the most common (52.2%), and tumor necrosis factor inhibitors had the highest incidence rate (4.25\/100 patient-years) among the various classes of advanced therapies. Diabetes mellitus (odds ratio = 4.508, 95% confidence interval: 1.246\u201316.316; p\u2009=\u20090.022) and lung disease (odds ratio = 4.554, 95% confidence interval: 1.056\u201319.637; p\u2009=\u20090.042) were independent predictors of serious infections.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Serious infections may develop among patients with rheumatoid arthritis receiving advanced therapy, with lung disease and diabetes mellitus identified as independent risk factors.
