[Clinical, bacteriological and therapeutic aspects of meningococcal meningitis in Dakar in 1999].
Two major outbreaks of meningitis due Neisseria meningitidis serogroup A occurred in Senegal in 1998 and 1999. The purpose of this report is to describe clinical, bacteriological and therapeutic findings in 70 patients admitted for cerebrospinal meningitis to the Infectious Disease Clinic at the Fann University Teaching Hospital in Dakar in 1999. Diagnosis was based on direct microscopic examination after Gram staining in 71% of the cases, culture in 76%, and detection of soluble antigens in cerebrospinal fluid in 24%. Median patient age was 20 years. The highest incidence, i.e. 66% of cases, was recorded during February, March and April. Meningitic syndrome and fever were observed with 86% of the cases. The average duration of antibiotic therapy was 8 days. Chloramphenicol was the most commonly used drug (84% of cases). All strains identified in cultures were sensitive to chloramphenicol, ceftriaxone and cefotaxime but resistant to cotrimoxazole. Outcome was favorable in 93% of the cases. Three patients (4%) died and two (3%) developed hearing loss. Despite the low death rate in this series of patients treated in a hospital setting, mass vaccination is still the most effective mean of controlling meningococcal meningitis.
