Long-term prognosis after H. influenzae meningitis: prospective evaluation
Developmental Medicine and Child Neurology
|June 1, 1982
Summary
Long-term outcomes for children recovering from Haemophilus influenzae type B meningitis are generally positive. Careful selection of control groups is crucial when assessing psychomotor development post-meningitis.
Area of Science:
- Pediatrics
- Neurology
- Infectious Diseases
Background:
- Haemophilus influenzae type B (Hib) meningitis can have long-term effects on child development.
- Understanding the sequelae in different age groups is important for prognosis and management.
Purpose of the Study:
- To prospectively evaluate the long-term outcomes of children who recovered from Hib meningitis.
- To compare developmental outcomes between infants and older children after Hib meningitis.
- To assess the need for appropriate control groups in psychometric testing.
Main Methods:
- Prospective, long-term evaluation of 22 children with a history of Hib meningitis.
- Children were divided into two age groups: infants (2 months-2 years) and older children (>4 years).
- Psychometric testing was performed on 15 children, with siblings used as controls.
Main Results:
- Only two children (one in each group) experienced neurological or auditory sequelae.
- No significant growth retardation was observed in any child.
- Psychometric testing revealed similar IQs between children and their siblings, suggesting potential limitations in the control group selection.
Conclusions:
- Most children recover from Hib meningitis without significant long-term neurological or auditory deficits.
- The study highlights the importance of carefully selecting control groups for psychometric evaluations in children post-meningitis.
- Sibling controls may not always be appropriate for assessing subtle developmental differences.
