| Abstract: | Twenty-four cases of Hemophilus influenzae pneumonia diagnosed by positive blood or pleural fluid cultures are compared to 43 cases previously reported in the literatrue. Frequently associated illnesses in both series include alcoholism, chronic airways obstruction and preceding respiratory tract infection. Moderate temperature elevation and slight leukocytosis were common on admission in both groups. Chest roentgenograms in our series revealed both bronchopneumonia (75 per cent) and lobar consolidation (38 per cent). Pleural disease occurred frequently, with two empyemas noted on admission and nine additional effusions developing during therapy. Treatment of choice was ampicillin. All five patients who did not receive ampicillin died, whereas 16 to 19 who received this drug survived. High mortality (33 per cent) in our series may be attributed to the advanced age of the patients and the presence of associated illnesses. In addition, a 10 year review suggests a true increase in the incidence of H. influenzae pneumonia in adults. |
