Background:
The recent increase in the incidence of Mycoplasma pneumoniae has renewed interest in this pathogen and the range of clinical manifestations it can cause. This study aims to describe clinical and CT features of community-acquired pneumonia caused by Mycoplasma pneumoniae (MCAP).
Methods:
We prospectively collected data on hospitalized adults with MCAP during the 2023-2024 outbreak. Clinical manifestation, laboratory data, and radiological abnormalities were evaluated. The data were analyzed using descriptive statistics.
Results:
A total of 40 patients were enrolled, with a median age of 35 (22; 45) years, and 24 (60%) were male. The primary symptoms were cough (40 patients, 100%), fever (38 patients, 95%), and general weakness (35 patients, 87.5%). Laboratory tests revealed a moderate increase in С-reactive protein levels, with a median of 77.1 (37.3;123.0) mg/L. The most common radiological findings were ground‑glass opacity in 36 patients (90%) and bronchial wall thickening in 33 patients (82.5%). No patients required admission to the intensive care unit, and there were no deaths during the hospital stay.
Conclusion:
In our study, MCAP predominantly affected young and middle-aged adults with a favorable course and prognosis. The current outbreak requires attention in terms of using optimal diagnostic and treatment methods.
Insights
Community-acquired pneumonia caused by Mycoplasma pneumoniae (MCAP) predominantly affected young adults during a 2023-2024 outbreak. Most patients experienced cough and fever, with ground-glass opacities on CT scans, and had a favorable prognosis.
