Pneumococcal bacteraemia--a study of 75 black children
Insights
Pneumococcal bacteraemia is a severe childhood infection, particularly in malnourished infants. High fatality rates are linked to malnutrition, meningitis, and co-infections, posing future treatment challenges.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Pneumococcal bacteraemia is a significant cause of childhood illness and mortality.
- Malnutrition and young age are identified risk factors for severe outcomes.
- Emerging antibiotic resistance complicates treatment strategies.
Purpose of the Study:
- To retrospectively analyze cases of pneumococcal bacteraemia in children.
- To identify risk factors and outcomes associated with this infection.
- To discuss host defense mechanisms and clinical associations.
Main Methods:
- Retrospective case record review of 75 children aged 0-10 years hospitalized with pneumococcal bacteraemia.
- Data collection included age, nutritional status, co-infections, and outcomes.
- Statistical analysis of case-fatality rates based on clinical factors.
Main Results:
- The overall case-fatality rate was 26.7%, with higher rates in autumn, meningitis, severe malnutrition, and associated infections.
- 67% of children were malnourished, 34% severely so.
- Infants under one year constituted half of the study population.
Conclusions:
- Pneumococcal bacteraemia represents a serious threat to children, especially those who are malnourished or have concurrent infections.
- Deficiencies in host defenses in young and malnourished children contribute to severity.
- The rise of penicillin-resistant strains necessitates ongoing vigilance and potential treatment modifications.
Abstract:
Seventy-five black children from 0 to ten years old with pneumococcal bacteraemia, who were hospitalized during a one-year period, were studied retrospectively from case records. Half the children were under one year and 68% under two years of age. Sixty-seven per cent were malnourished, 34% severely so. The overall case-fatality-rate was 26.7% being highest in children presenting in autumn (52.4%) and in those with meningitis (54.5%), severe protein-calorie malnutrition (42.8%) or associated infections (61.5%). Host defences against the pneumococcus are discussed, especially in relation to their deficiencies in malnourished and young children. Special mention is made of early-onset neonatal sepsis due to the pneumococcus and of the association between pneumococcal bacteraemia and acute post-streptococcal glomerulonephritis. This study indicates that pneumococcal bacteraemia is a serious infection in children, especially in those with malnutrition and other infections. In view of the emergence of penicillin-resistant strains, its treatment may become more difficult in the future.
