Staphylococcal lower respiratory infection in children.

A prospective study of staphylococcal lower respiratory infection in 31 children aged 1-48 months has shown that radiologically, patchy consolidation was the single most common lesion, followed by pleural effusion with or without pneumothorax. Although the mean respiratory rate was 65/minute, it was below 50/minute in 8 cases. Complications include heart failure in 9 cases and severe anaemia necessitating blood transfusion in 9 others, seven (78%) of whom had pleural effusion. Finally diagnoses were bronchopneumonia alone in 16 (52%) cases, pyopneumothorax alone in 6 (19%), pyopneumothorax plus pneumonia in 5 (16%), pleural effusion in 2 (6%) cases and one case each of lobar pneumonia alone and a combination of lobar and bronchopneumonia. Staphylococcus aureus was isolated from the blood in 8 (62%) of 13 children with pleural effusion, indicating a need to consider parenteral antibiotic administration in the initial management of children with staphylococcal pleural effusion. Three (9.7%) patients died; they were all malnourished children who did not receive antibiotics prior to presentation; they all had bronchopneumonia, positive blood cultures and respiratory rates of 60/minute.

[Abscessing staphylococcal pneumonia following virus infection of the respiratory tract].

Severe abscessing staphylococcic pneumonia due to viral infections of the respiratory tract developed in two infants age 1 7/12 and 3 1/12 years. Clinical features, roentgenological symptomatology and the importance of bacteriological and virological diagnostics are discussed, fundamental characteristics of the chemotherapy are explained. The causal relation between viral infections of the respiratory tract and abscessing staphyloccic pneumonia as well as the special diagnostical and therapeutic problems are discussed.

Effects of murine endotoxemia on lymphocyte subsets and clearance of staphylococcal pulmonary infection.

In a model of staphylococcal pneumonia initiated during systemic endotoxemia in BALB/c mice, a significant reduction of the number of circulating CD4+ and CD8+ T-lymphocytes, B-lymphocytes, and NK cells, as well as lung-resident total T- and CD4+ T-lymphocytes was demonstrated. Staphylococcus aureus exposure only induced a similar decrease of lymphocyte subsets in the blood. However, the number of lung-resident total T- and CD4+ T-lymphocytes was increased. More viable bacteria were recovered from the lungs of S. aureus-infected mice than from those animals previously treated with lipopolysaccharide (LPS) followed by a staphylococcal challenge. These results indicate that LPS-induced reduction in the number of circulating lymphocyte subsets and lung-resident total T- and CD4+ T-lymphocytes do not increase susceptibility to staphylococcal respiratory infection. Moreover, LPS challenge prior to S. aureus exposure significantly improves clearance of the bacteria in the lung.

Epidemiology of Staphylococcus aureus in patients with cystic fibrosis.

Seven hundred and thirty-four isolates of Staphylococcus aureus, recovered from the sputum of 238 cystic fibrosis patients in six French hospitals, were characterized by esterase electrophoretic typing, capsular polysaccharide serotyping and phage typing and tested against 14 antibiotics for sensitivity. Thirty-four esterase electrophoretic types were found with a genotypic diversity coefficient of 0.91. Five hundred and forty-eight (78.7%) isolates produced capsular polysaccharide and 350 (50.3%) were type 8. Four hundred and sixty isolates (66.6%) were phage typable and 202 (28.2%) were lysed by group III bacteriophages. No esterase electrophoretic type, capsular type or phage type was specific to cystic fibrosis. Isolates belonged to a wide range of types, similar to strains acquired outside hospitals. Eighty-five patients had three or more consecutive isolates over at least 6 months. The ability of S. aureus to persist for long periods of time has been demonstrated in 73% of them. Methicillin-resistance was encountered among 73 strains (9.8%) which were also multiresistant. Two hundred and eighty-nine (39.9%) strains were sensitive to all antibiotics tested except to penicillin. Pristinamycin and co-trimoxazole were the most effective antibiotics. These results could contribute to the elaboration of a rational approach to the prophylaxis and therapy of respiratory staphylococcal infections in cystic fibrosis patients.
