Primary staphylococcal pneumonia in young children: a review of 100 cases.

Abstract

Staphylococcus aureus (S. aureus) is responsible for a small proportion of acute respiratory infections in children. Nevertheless a high index of suspicion is required because of the potential for rapid progression, the need for antibiotics different to those routinely administered in the treatment of pneumonia, and the high incidence of complications. There are few data from developing countries. The objective of this retrospective review was to document the natural history of primary staphylococcal pneumonia at Red Cross Childrens' Hospital in Cape Town over a 7-year period (1989-1995). Staphylococcal pneumonia was defined as acute pneumonia with microbiological evidence of S. aureus or with characteristic radiological features. One hundred patients were identified. The median age was 5 months, 78 patients being below one year of age. Cough and fever were present in almost all patients at the time of presentation. Tachypnoea, recession, dullness, and crepitations were commonly elicited signs. Initial chest radiographs revealed empyema, pleural effusion, or pyopneumothorax in 67 patients. A further 26 patients developed such changes on subsequent chest radiographs. Pneumatocoeles were identified in 37 patients--most of these were only noted on radiographs taken some days after admission. Microbiological confirmation was obtained in 92 cases. S. aureus was isolated in 23/98 blood cultures, 62/67 pleural aspirates, and from tracheal aspirates in 16 cases. Intercostal drains were inserted in 67 cases and 20 children underwent thoracotomy. The case fatality rate was 7 per cent. This study shows that primary staphylococcal pneumonia is chiefly a disease of infants. Symptoms and signs were similar as for other forms of acute pneumonia, although in the majority of cases chest radiographs taken at the time of admission suggested the diagnosis. Treatment with antibiotics and drainage of empyema resulted in a good outcome in the majority of cases.
