[Pédiatric haemophilus influenzae b meningitis in Dakar]

This study had for aim to determine the etiology of Haemophilus b pediatric meningitis.

A retrospective study of 216 biologically confirmed cases was carried out during 6 years (January 1995- December 2000) on children 0 to 15 years of age, hospitalized at the Albert Royer Children Hospital Center.

Haemophilus influenzae b is the first cause of pediatric meningitis (19.7%) followed by Nesseria meningitidis (14.5%), and Streptococcus pneumoniae (13.6%). The Haemophilus influenzae b meningitis cases are distributed all year round with a peak between January and March, that is to say, during the dry and cool season. They affect children at an average age of 11.7 months, with a sex ratio of 1.1 for boys. Almost all of the patients live in the low-socio-economic areas of the Dakar suburbs (92.8%). More than 90% of the H. influenzae b isolates are sensitive to ceftriaxone (96%) chloramphenicol (93%), and to ampicillin (91%). Clinical evolution is marked by death (17.8%) and recovery with psychological, sensory, and motor sequels (19.9%).

This report should help to include the combined vaccine Antihaemophilus influenzae b in the Senegalese Broad Vaccination Program. The final aim is the reduction of morbidity and mortality of infections due to Haemophilus influenzae b.
