Mycoplamsal pneumonia is known to be a prevalent disease in children. But it also freuently develops in adults and the elderly.
We studied the clinical features of mycoplamsal pneumonia in adults and the elderly, and compared these with those of children.
The clinical characteristics of 50 patients with mycoplamal pneumonia, which was diagnosed by serological methods (mycoplasmal antibody and cold agglutinin titer), were investigated from October 1983 to April 1988 at Severance Hospital. The results were as follows:
1) The incidence was highest in patients 30~39 years old(30%), follwed by patients 20~29 years old(28%), and 40~50 years old(18%), and the male to female ratio was 1:1.6.
3) The chief complaints were cough(72%), sputum(38%), fever(22%), dyspnea(14%), and chest pain(8%).
4) the auscultation findings of the chest were moist rales(34%), coarse breath sounds(17%), and rhonchi (15%). No abnormal breath sounds were heard in 22% of the patients.
5) The leukocyte counts in peripheral blood were 5,000~10,000 in 70%, 16%, and the percentage of neutrophils were 51~60% in 30%, 71~80% in 25%, 61~70% in 21% of cases.
6) The involved sites on chest X-ray were the left lower lobe(24%), right lower lobe(22%), right middle lobe(22%), and left middle lobe(20%).
7) The complications were abnormal liver function, microscopic hematuria, paranasal sinusitis, myringitis and abnormal pulmonary function test.
8) The associated diseases were pulmonary tuberculosis, bronchitis, bronchial asthma, diffuse interstitial lung disease, pneumonia.
In conclusion, there were no definite differences in the clinical features of mycoplasmal pneumonia between adults and children except that adults showed less severe symptoms and complications, and more associated diseases.
