Prevalence and case-control study of cerebral malaria in Limbe of the South-West Cameroon.
A study was carried out in Limbe and its environs to determine the prevalence of cerebral malaria vis- a- vis uncomplicated malaria, and to assess the importance of parasitaemia level, packed cell volume and hypoglucaemia as predictors of cerebral malaria. Data were obtained using a questionnaire administered to 650 people aged between 6 months and 70 years, and by a case-control study on 90 people (30 cases and 60 controls) aged between 6 months and fifteen years. The results of the questionnaire study revealed uncomplicated malaria prevalence rate of 50.9% as against 7.1% for cerebral malaria. The highest prevalence of these infections occurred in the 0-5 years age group, dropping in people aged 16 years and above. The case-control study revealed high parasitaemia (100,000-500,000 parasites/mm3 of blood) in uncomplicated malaria patients and hyperparasitaemia (>500,000 parasites/mm3 of blood) in cerebral malaria patients. Patients with uncomplicated malaria had either normal haemoglobin (PCV<18%). Hypoglycaemia (>40 mg glucose/dl) was recorded in 12.9%of cerebral malaria patients, but in none of the patients with uncomplicated malaria.
