Abstract

We classified 1017 patients with community-acquired pneumonia requiring hospitalization experienced in Kawasaki Medical School Kawasaki Hospital during the past 15 years into five age groups (< or = 54 years old, 55-64 years old, 65-74 years old, 75-84 years old, > or = 85 years old). With particular emphasis on the elderly patients, we then compared the clinical and microbiological findings in the five groups. The results were as follows; (1) Half of patients in the over 85 years old group were bed-ridden. (2) The proportion receiving antibiotics before hospitalization decreased with age. (3) There were striking atypical pneumonic symptoms, such as dyspnea and consciousness disturbance in the two age groups over 75 years old. (4) Hypotension (shock) increased with age. (5) Markers of nutritional conditions, such as serum protein, albumin, cholinesterase, and hypoxia remarkably increased in the two age groups over 75 years old. (6) There were no significant differences in the isolation rate of etiological microorganisms. (7) The number of polymicrobial agents in the < or = 54 years old group was lower than that in the other age groups. (8) Mycoplasma pneumoniae was most significantly higher in < or = 54 years old group, Haemoph...Continue Reading
