[Clinical study of 37 pneumonia patients in whom MRSA was identified from sputum].
When we studied the clinical aspects of 37 pneumonia patients with underlying respiratory disease in whom MRSA 1 + was identified from sputum, 43.2% of these 37 pneumonia cases were diagnosed as MRSA colonization. The whole clinical course of these pneumonia patients with MRSA colonization was average 39.5 days, on the other hand, the whole clinical course of MRSA pneumonia group was 55.3 days. We should consider that MRSA must be a cause of pneumonia, in only such cases as follows; (1) patients with unstable diabetes mellitus, or with long-term administration of steroid, (2) patients with infiltrative shadows appeared not only in the lower lobe but also the upper lobe in the chest x-ray films, (3) patients with remarkable decrease of PaO2 or patients who failed to recover within one month from MRSA isolation, (4) patients with nosocomial pneumonia or patients with poor performance status or poor prognosis, (5) patients with purulent sputum containing MRSA or other bacteria such as K. pneumoniae etc and patients who failed to respond to general antibacterial agents.
