Bronchopneumonia patterns on X-ray, as well as bronchial wall thickening, bilateral distribution, and segmental pattern on CT were more common in MC-CAP patients than in SP-CAP patients ( p < 0.01). Although winter is an influenza season in Japan, co-infection with influenza virus was less common in MC-CAP compared to SP-CAP patients (3% vs. Approximately half of asthmatic MC-CAP and SP-CAP patients had asthma attacks. Compared to those with SP-CAP, MC-CAP patients were older ( p < 0.01) and more likely to have underlying pulmonary diseases such as asthma and bronchiectasis ( p < 0.01). Although seasonality was not observed in SP-CAP, almost half of MC-CAP patients were admitted in the winter. We identified 134 MC-CAP and 130 SP-CAP patients. pneumoniae alone was isolated from their sputum by bacterial cultures. Among these, we included patients whom either M. This retrospective study screened CAP patients aged over 20 years visiting or admitted to Okinawa Miyako Hospital between May 2013 and April 2018. We aimed to clarify the clinical characteristics of MC-CAP by comparing those of SP-CAP, as well as the utility of sputum Gram staining. However, no past study compared clinical characteristics of MC-CAP and SP-CAP by statistical analysis. pneumoniae (SP-CAP) in clinical practice.
