[Severe infections by Haemophilus influenzae in children]
Insights
Serious Haemophilus influenzae infections in children, particularly meningitis and empyema, are frequent and severe. Diagnostic cultures of bodily fluids are effective for identifying these critical pediatric illnesses.
Area of Science:
- Pediatrics
- Infectious Diseases
- Microbiology
Background:
- Recent publications highlight the increasing severity and incidence of serious infections caused by Haemophilus influenzae in children.
- Haemophilus influenzae infections pose a significant threat to pediatric health, necessitating a deeper understanding of their epidemiology and clinical presentation.
Purpose of the Study:
- To analyze the frequency and clinical features of Haemophilus influenzae infections in children under three years of age.
- To evaluate the diagnostic effectiveness of various sample cultures for severe Haemophilus influenzae infections.
Main Methods:
- Retrospective analysis of clinical records from January 1970 to March 1976.
- Inclusion criteria: 120 children under 3 years with H. influenzae isolated from CSF, blood, bone marrow, pleural, or synovial fluids.
- Data collected on clinical syndromes, associated localizations, and mortality.
Main Results:
- Bacterial meningitis was the most common syndrome (83.3%), often associated with other localizations (27%).
- Empyema (12.5%) was frequently linked with meningitis (46.6%).
- Mortality rate was 26.6% in the studied cohort, indicating the severity of these infections.
Conclusions:
- Haemophilus influenzae infections, especially meningitis and empyema, are frequent and severe in children under three.
- Cultures of cerebrospinal fluid (CSF), blood, and bone marrow are effective diagnostic methods for severe H. influenzae infections.
- There is a notable tendency for increased frequency of these infections in recent years, underscoring the need for continued surveillance and intervention.
Abstract:
Severity and increasing incidence of serious infections due to Haemophilus influenzae in children have been stressed in recent publications. An analysis of the clinical records of the Department of Pediatrics, Hospital Roberto del Río (Santiago, Chile) was made in order to gather information about frequency and clinical feature of this kind of infections in our environement. 120 children under 3 years of age in whom H. influenzae was isolated in samples of one or more of the following sources: CSF, blood, bone marrow, pleural and synovial fluids, were admitted from January 1970 to March 1976. Among the different syndromes observed, bacterial meningitis (83.3%) was associated with other localizations in 27%. Empyema (12.5%) was often (46.6%) associated with meningitis. Both clinical entities were the most common and with a definite tendency to increase their frequency in last years. Cultures of CSF, blood and bone marrow were considered effective tests for diagnosis in severe infections due to H. influenzae. Although precise incidence figures may not be obtained from the present data, this kind of diseases may be considered frequent and severe (mortality: 26.6% in this study).
