[Study on septicaemia in infants and children in the past 20 years. Part 1. An analysis of causal organisms].
Causal organisms and their changes were evaluated in 158 cases of septicaemia admitted to Jikei University Hospital from 1975 to 1994. Eighty patients (50.6%) were aged less than 1 year, and 37 patients (23.4%) were newborns. The average mortality rate was 18.4%. The mortality rate between 1975 and 1984 was 26.8%, and that of the past 10 years (from 1985 to 1994) decreased to 13.7%. Staphylococcus aureus (29 cases, 19.4%) was the most common pathogens isolated, followed by Pseudomonas sp. (24 cases, 15.2%), Escherichia coli (19 cases, 12.0%), and Haemophilus influenzae (18 cases, 11.4%). H. influenzae, Acinetobacter sp., Streptococcus pneumoniae and Group B streptococcus (GBS) increased in the past 10 years (from 1985 to 1994), compared with the preceding 10 years (from 1975 to 1984). The mortality rate of Klebsiella sp. septicaemia (28.6%) was highest, followed by Pseudomonas sp. (25.0%), S. aureus (24.1%), S. pneumoniae (22.2%). H. influenzae and Acinetobacter sp. septicaemia were not fatal. E. coli and GBS were common among neonates and patients aged less than 1 year. H. influenzae septicaemia occurred mainly in patients with meningitis, in those younger than school age. Acinetobacter sp. was common among neonates and children with leukaemia Pseudomonas sp., Klebsiella sp., and Acinetobacter sp. were mainly detected in patients with underlying diseases. E. coli, H. influenzae, S. pneumoniae and GBS were mainly detected in patients without underlying diseases.
