The high human immunodeficiency virus (HIV) prevalence in sub-Saharan Africa has markedly changed the epidemiology and presentation of adult meningitis. We conducted a systematic review using PubMed, Embase, Ovid, CENTRAL, and African Index Medicus to identify studies in Africa with data on neurological outcomes in adults after meningitis. We found 22 articles meeting inclusion criteria. From 4 studies with predominately pneumococcal meningitis, a median of 19% of survivors experienced hearing loss up to 40 days. Two studies of cryptococcal meningitis evaluated 6- to 12-month outcomes; in one, 41% of survivors had global neurocognitive impairment and 20% severe impairment at 1 year, and in a second 30% of survivors had intermediate disability and 10% severe disability at 6 months. A single small study of patients with tuberculosis/HIV found marked disability in 20% (6 of 30) at 9 months. Despite the high burden of meningitis in sub-Saharan Africa, little is known about neurological outcomes of patients with HIV-associated meningitides.

Neurological Sequelae of Adult Meningitis in Africa: A Systematic Literature Review

Global Case Fatality of Bacterial Meningitis During an 80-Year Period

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.
