Clinical characteristics and risk factors associated with severe community-acquired pneumonia infected by <i>Chlamydia psittaci</i>.

ABSTRACT: The study aimed to describe the clinical features of psittacosis pneumonia and identify risk factors associated with severe psittacosis pneumonia. We retrospectively collected data from patients with psittacosis pneumonia, confirmed by metagenomic next-generation sequencing (mNGS) from January 2022 to June 2024 and analyzed differences between severe and non-severe groups. A total of 24 patients (eight severe/16 non-severe) were diagnosed with psittacosis, and 33.3% had severe psittacosis pneumonia. The levels of white blood cells (WBCs), neutrophils, neutrophil-to-lymphocyte ratio (NLR), hypersensitive C-reactive protein (hs-CRP), and procalcitonin (PCT) and the detection rate of fungi by mNGS were significantly higher in the severe group than in the non-severe group.
