Acute bacterial meningitis at the 'Complexe Pédiatrique' of Bangui, Central African Republic.
To precis the aetiologies of children meningitis and the susceptibility to antibiotics of bacteria responsible for meningitis in Bangui, we conducted a prospective study between October 2004 and September 2005, at the 'Complexe Pédiatrique de Bangui', Central African Republic (CAR). Children from 1 day to 16 years with suspected meningitis and who underwent a lumbar puncture were enrolled. Gram staining, culture on chocolate blood medium, cell count, biochemistry (protein level, glucose ratio), capsular antigen detection were performed for each cerebrospinal fluid. MICs were determined by the E-test method. Four hundred and seventeen patients were enrolled during the study period; 130 were proven acute bacterial meningitis and 37 probable bacterial meningitis. Among proven bacterial meningitis, Streptococcus pneumoniae was the most common organism responsible for meningitis (62 cases, 48%) followed by Haemophilus influenzae (46 cases, 35%) and by Neisseria meningitidis and Salmonella sp. (8 cases, 6% each). Ninety-four percent and 96% of S. pneumoniae strains tested remain susceptible to benzylpenicilline and chloramphenicol, respectively. A beta-lactamase was detected in 92% of H. influenzae strains tested. However, MICs 50% and 90% for amoxicillin were found to be 1 and 4 mg/l, respectively and 33% of these strains were resistant to chloramphenicol. The global mortality rate was 35% (59/167). This mortality rate was 47% for S. pneumoniae, 33% for H. influenzae, 62% for Salmonella sp. and 13% for N. meningitidis. The probabilistic treatment with ampicillin and chloramphenicol usually administered for children meningitis in Bangui must be reconsidered particularly in cases of H. influenzae meningitis. It is of importance to reduce the presentation delays of children with suspected meningitis in Bangui. The H. influenzae b immunization would allow a dramatic reduction of meningitis cases and deaths in Central African children.
