Survival and sequelae of meningococcal meningitis in Ghana.

Abstract:

BACKGROUND:Meningococcal meningitis epidemics are frequent in the Sahel zone of Africa but there is little information on the frequency of long-term sequelae. We analysed excess mortality in the two years following the 1997 epidemic in northern Ghana and carried out a case-control study to assess sequelae in the survivors. METHODS:Two-year survival of 696 meningitis cases recorded at the War Memorial Hospital, Navrongo, was analysed using data from a demographic surveillance system. A structured questionnaire on disability and on psychiatric, neuropsychological and behavioural problems was administered to 505 of the survivors and 505 age- sex- and location-matched controls as well as to their respective relatives. Cases and controls underwent full neurological and neuropsychological examination and were evaluated for hearing impairment by audiometry. RESULTS:Survival rates after the first month following the attack were similar in cases and controls. Hearing impairment was the major sequela, and was reported in 6 per cent of cases and 2 per cent of controls (odds ratio [OR] = 3.10; 95% CI : 1.48-7.09). Audiometry detected severe and profound hearing loss in the worse affected ear (> or =70 db) in 8/496 (1.6%) survivors but in only one control. Survivors of meningitis were more likely to suffer from feelings of tiredness (OR = 1.47; 95% CI : 1.03-2.11) and were more often reported by relatives to have insomnia (OR = 2.31; 95% CI : 1.17-4.82) and daily alcohol consumption. INTERPRETATION:Meningococcal meningitis annually causes approximately 10 000 cases of deafness in sub-Saharan Africa; there is a need for early detection of affected survivors and promotion of simple hearing devices. There is a sizeable burden of depressive disorders secondary to meningitis which should be identified and looked after appropriately.
