Then, we analyzed and compared their demographics, disease characteristics, and risk factors for infection. Among the whole cohort (n\u2009=\u2009118), the incidence of pulmonary infections was 56.78%. The occurrence of rheumatoid arthritis, systemic lupus erythematosus, and vasculitis was found to be associated with an increased risk of pulmonary infection. Sputum culture identified Pseudomonas aeruginosa and Klebsiella pneumoniae as the predominant pathogens in the infected group. Notably, symptoms such as joint pains (p\u2009=\u20090.018) and morning stiffness (p\u2009=\u20090.017) were significantly more common in the infected group compared to the noninfected group. Moreover, our findings revealed that elevated levels of C\u2010reactive protein and complement C3, along with bronchial expansion observed on high\u2010resolution computed tomography (HRCT), were significant independent factors in the infection group. Conversely, pulmonary interstitial changes identified through HRCT (OR: 0.135, 95% CI: 0.030\u20130.612, p\u2009=\u20090.009) were significantly associated with the non\u2010infection group. Overall, this study provides valuable insights into managing CTD patients with bronchiectasis, emphasizing early detection and tailored approaches to prevent and treat pulmonary infections for better outcomes.<\/jats:p>","DOI":"10.1111\/apm.13424","type":"journal-article","created":{"date-parts":[[2024,5,27]],"date-time":"2024-05-27T06:23:32Z","timestamp":1716791012000},"page":"571-580","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical
