Treatment of imported malaria in adults: a multicentre study in France.

摘要

BACKGROUND: Data about anti-malarial drugs prescription practices in Europe and the safety of imported malaria treatments are scanty. In 1999, a French consensus development conference published guidelines for the prevention and treatment of imported P. falciparum malaria. The impact of these guidelines has not been evaluated. AIM: To investigate the impact of these guidelines on the prescription of anti-malarials, and to evaluate the incidence of acute drug events (ADEs) leading to discontinuation of treatment. DESIGN: Cross-sectional survey. METHODS: Members of the medical staff in 14 French infectious and tropical disease wards completed a standardized form for each patient treated for imported malaria in 2001. A propensity score matching technique was used to estimate the risk of ADEs leading to discontinuation of the regimen. RESULTS: In the 474 patients studied, quinine was the first-line anti-malarial most often prescribed. Only 3 of patients received halofantrine. Mefloquine was associated with a RR of 4.9 (95CI 3.2-7.4, p < 0.00001) risk of discontinuation of treatment due to ADEs. DISCUSSION: The very limited use of halofantrine indicates that the main practice recommendations of the guidelines have been taken into account. Mefloquine was associated with a substantial risk of discontinuing the treatment because of ADEs. This is a serious limitation for the use of mefloquine in the treatment of out-patients with imported malaria.
