Chloroquine efficacy in the treatment of uncomplicated malaria at three sentinel sites in northern Togo.

In Togo, chloroquine (CQ) remains the first-line drug for the treatment of uncomplicated, Plasmodium falciparum malaria. In the absence of recent data on the level of parasite resistance to antimalarial drugs, Togo's National Malaria Control Programme (NMCP) decided to assess the current efficacy of CQ in the treatment of uncomplicated, P. falciparum malaria at three sentinel sites in the north of the country. Between the September and November of 2001, the World Health Organization's standard 14-day protocol was used to investigate 153 malarious children aged 6-59 months old (46 from Sokode, 54 from Niamtougou and 53 from Dapaong). Of the subjects from Sokode, Niamtougou and Dapaong, early treatment failure was observed in 0%, 7% and 12%, late treatment failure in 0%, 11% and 17%, and overall parasitological failure in 0%, 45% [with a 95% confidence interval (CI) of 39%-51%] and 62% (CI=54%-70%), respectively. Even within northern Togo, there is clearly considerable geographical variation in the level of resistance to CQ. Before an efficient antimalarial-drug policy can be developed, there is an urgent need to develop and use the national surveillance system further, to collect relevant data on the efficacies of CQ and other antimalarial drugs, such as amodiaquine and sulfadoxine-pyrimethamine.

Implementation of malaria control.

Global trends of infant and child mortality have decreased over the last 30 years, while the proportion of malaria deaths has progressively increased due to the deteriorating situation in sub-Saharan Africa. The Global Malaria Control Strategy promoted by WHO has encountered several obstacles to its implementation. Early diagnosis and prompt treatment can reduce malaria mortality, but there is still low investment on safe and effective modalities of care delivery at the periphery, where most of the malaria burden exists. Selective vector control (indoor residual spraying and insecticide-treated nets) plays a significant role outside Africa, but its wider use is limited by cost/affordability problems and operational issues (supply, delivery and logistics). Alternative methods such as environmental management and biological control are cost-effective only under very specific epidemiological situations. In most countries forecasting, early detection and containment of malaria epidemics is deficient, and there is separation between the research and control communities, particularly in Africa. Involvement of the internal agencies, strategic investments in capacity building and institutional networking are needed to strengthen capacity for malaria and research in the countries. The major responsibility is to guide the expenditure made by the communities (which far out-weigh the limited share of national health budgets) towards the most cost-effective approaches to reduce malaria mortality and morbidity.

[Severe malaria in children in Togo].

BACKGROUND: The definition of severe malaria is no longer limited to cerebral malaria, but is as well extended to other clinical forms of the disease. This work analyses epidemiological, clinical and evolutive aspects of severe malaria in Togo. PATIENTS AND METHODS: This study included 549 children, aged from 0 to 15 years, hospitalized in 1994-5 in the pediatric department of the Lome-Tokoin University Teaching Hospital for severe malaria as defined by World Health Organization (WHO) criteria. RESULTS: The hospitalization frequency was 7.44%; the maximum frequency was from 1 to 5 years of age, but 6.56% of patients were more than 10 years old. The most frequent clinical form was that of severe anemia, followed by cerebral complications, as seen in many African countries. The death rate was 18.94% and the proportional mortality was 8.21%; 2.73% of the patients had neurological sequelae (behaviour disturbances in five cases, aphasia in four, hemiplegia in three, mumbling in one, oculomotor paralysis in one, and cerebellar ataxia in one). Hypoglycemia was fairly frequent (11.6%) and was associated with a poor prognosis. CONCLUSION: It is possible to improve severe malaria prognosis in Africa by insisting not only on better equipment in intensive care wards, but also on improved and early management of hypoglycemia.

[Resurgence of endemic yaws in Togo. Cause and eradication approach].

In Togo, since 1940, yaws declared endemic has been controlled after the 1956 and 1961 eradication campaign. Nowadays, unfortunately, the mutilating treponematosis has reappeared in force. Hence, Togolese Health Officers are in search of ways and means to eradicate the disease so as to prevent handicaps for future generations.

[Cysticercosis and neurocysticercosis: epidemiological survey in North Togo].

An epidemiologic survey was carried out by a team of medical doctors working in the Kozah district of North Togo during April 1987. It was designed to evaluate the incidence of epilepsy and cysticercosis, taking a sample population of 5,264 subjects aged over 15 years old. 81.7% of the population feed on pigs which are allowed to roam freely in the vicinity of people's habitations. Cysticercosis (123 cases; incidence 23.3 cases per thousand) was diagnosed when one of the following three tests gave a positive result:--serum sample greater than or equal to 0.400 OD with ELISA test (101 cas),--identification of a cysticercosis cyst on anatomopathological examination of subcutaneous cysts (12 cases),--presence of typical calcification patterns revealed by cranial or muscle X-rays (21 cases in 18 patients). General epilepsy or partial motor fits were entirely clinically diagnosed (88 cases; 16 per thousand of population). Cysticercosis proved to be the cause of 29.5% epileptic sufferers, onset occurring after the age of 50 in 66% of these patients.
