Acute bacterial meningitis in children presenting to the Royal Liverpool Children's Hospital, Liverpool, UK and the Queen Elizabeth Central Hospital in Blantyre, Malawi: a world of difference.
BACKGROUND
Bacterial meningitis is a serious childhood illness worldwide. Children can now be immunised against meningitis with conjugate vaccines. The outcome of bacterial meningitis in British and Malawian children before the introduction of these vaccines was compared.


METHODS
All children with culture-positive bacterial meningitis treated in the Royal Liverpool Children's Hospital (RLCH), UK during 1984-1991 (n=197) and in the Children's Unit, Queen Elizabeth Central Hospital (QECH), Blantyre, Malawi during 1996-1997 (n=175) were studied.


RESULTS
Children at QECH presented later and were more often comatose and malnourished. Mortality was 7% in RLCH compared with 41% in QECH. Three organisms caused most cases of meningitis: N. meningitidis 56% vs 4%, H. influenzae b 27% vs 25%, and S. pneumoniae 11% vs 35% in RLCH and QECH, respectively. Mortality was lower in RLCH for each organism: N. meningitidis 10% vs 28%, H. influenzae b 6% vs 43%, S. pneumoniae 0% vs 46%.


CONCLUSIONS
Mortality from bacterial meningitis in Malawian children is much higher than in British children, even when infected with the same organisms. This might be owing to delay in presentation, malnutrition and HIV infection. Immunisation of Malawian children with conjugate vaccines should continue to develop since their risk of dying from meningitis is five times greater than that of British children.
