malaria - Opis:
- In Sahelian countries such as Burkina Faso, malaria transmission is seasonal with a high incidence of transmission during the rainy season. This study aimed to compare the effectiveness of the two recommended treatments (Artemether-Lumefantrine and Artesunate-Amodiaquine) for uncomplicated malaria in Burkina Faso regarding this seasonal variation of malaria transmission. This is part of a randomized open label trial comparing the effectiveness and safety of Artemether-Lumefantrine versus Artesunate-Amodiaquine according to routine practice in Nanoro. Patients with uncomplicated falciparum malaria were recruited all year round and followed-up for 28 days. To distinguish recrudescences from new infections, dried blood spots from day 0 and day of recurrent parasitaemia were used for nested-PCR genotyping of the polymorphic loci of the merozoite surface proteins 1 and 2. Seasonal influence was investigated by assessing the treatment outcomes according to the recruitment period of the patients. Two main groups (dry season versus rainy season) were defined following the seasonal characteristics of the study area. In Artemether- Lumefantrine group, the uncorrected cure rate was 76.5% in dry season versus 37.9% in rainy season. In Artesunate-Amodiaquine group, this was 93.3% and 57.1% during dry and rainy seasons, respectively. After PCR adjustment, the cure rate decreased from 85.9% in dry season to 75.0% in rainy season in Artemether-Lumefantrine group. In Artesunate-Amodiaquine group, it was 93.3% in dry season and 80.7% during the rainy season. During the rainy season around 50% of patients had a new malaria episode by Day 28. The cure rate of both Artemether-Lumefantrine and Artesunate-Amodiaquine treatments was higher in dry season compared to rainy season due to high incidence of reinfections during the rainy season. For this reason, in addition to the curative effect, the post-treatment prophylactic effect should be taken into account in the choice of antimalarial regimens.
