Endemic bacterial meningitis in Sudanese children: aetiology, clinical findings, treatment and short-term outcome

Abstract

During the period April 1985 to November 1986 (18 months), 196 children (of age greater than 1 month) admitted to the Children's Emergency Hospital in Khartoum, Sudan, with clinical suspicion of meningitis/meningoencephalitis were followed up prospectively. Bacterial meningitis was diagnosed by culture, direct microscopy and/or antigen-detecting assays (co-agglutination and enzyme immunoassay) in 44 infants (25 Haemophilus influenzae type b, 8 Neisseria meningitidis, 7 Streptococcus pneumoniae, 3 enterobacteria and one mixed infection), aseptic meningitis in 52, cerebral malaria in 4 and febrile convulsions in 96. The majority of cases of bacterial meningitis were boys and 57% of those in whom H. influenzae was the commonest isolate were less than 1 year old. The presenting signs and symptoms are described as well as the transient and permanent short-term sequelae. The total mortality from bacterial meningitis was 19%, permanent neurological sequelae were seen in 26% of survivors. Prospective follow-up, including audiometry, of 35 children 1-2 months after discharge showed that 11% had hemiplegia and 20% had hearing impairment. The potential impact of vaccination against invasive H. influenzae infections is discussed.
