Background: The aim of this study was to investigate the clinical features and etiology in patients with community-acquired pneumonia (CAP) in southern China. Methods: A total of 342 patients who presented community-acquired pneumonia (CAP) from January 2019 to December 2019 were enrolled in this study. The respiratory pathogens in nine test and loop-mediated isothermal amplification (LAMP) detection were used to identify pathogens.
Results: The mean age of this study population was 60.89 ± 18.87 years. The total incidences of CAP were more prevalent in males (60.5%, 207/342) than females (39.5%, 135/342), and the percentage was 65.8% (225/342) CAP patients in summer and autumn. The main causative pathogens were identified in 96/342 (28.1 %) patients. Of these, 14 (14.6 %) were MP infection, the most frequently isolated microorganism. Bacterial infection in the single infection was present in 47 (47/96, 49.0%). Mixed infections were demonstrated in 26 (26/96, 27.1%). MRSA infection was close to patients with systemic diseases (P = 0.001). Factors that were associated with systemic disease was the age >65 (OR 5.555, 95%CI 3.402-9.071, P<0.001).
Conclusions: MP is common organisms isolated in community-acquired pneumonia. The year of above 65, the count of WBC and mixed pathogens infections may be associated with an increased risk of CAP patients with systemic disease.
