[Septic meningitis in children in Rwanda from 1983 to 1990. Retrospective study at the Kigali Hospital Center]

To assess septic meningitis in pediatric units in terms of the bacteriologic distribution, mortality, and groups at risk, we conducted a retrospective study in the pediatric department of the Kigali Hospital Center (Rwanda). Based on bacteriologic study of 1215 cerebrospinal fluid samples, there were 321 cases of septic meningitis due to identifiable germs and 68 involving cloudy fluid with no detectable germs, i.e. 1.5% of admissions to the Pediatric Unit of the Kigali Hospital Center. The most common organisms were pneumococcus (36.5%), Haemophilus influenzae (31%), salmonella (13%), and meningococcus (11.5%). Most of the children (75%) presenting septic meningitis were under the age of 5 years. Overall mortality was 38% with rates of 52% and 39% for cases involving pneumococcus and salmonella respectively. The predominant clinical symptoms of pneumococcus meningitis were coma (p:0.000055) and respiratory compromise (p:0.02). In contrast Haemophilus influenzae meningitis was associated with a lower incidence of coma (p:0.05) and malnutrition (p:0.017). Salmonella meningitis was characterized by a higher incidence of fever over 38.9 degrees C (p:0.025) and malnutrition (p:0.01). In patients with meningococcus meningitis, the incidence of convulsions appeared to be higher, at the threshold of statistical significance (p:0.052), whereas coma (p:0062) and respiratory distress (p:0.0024) were uncommon. Independently of etiology, no clinical symptom was associated with a statistically higher risk for death.
