Background: Artesunate-amodiaquine combination for the treatment of childhood malaria is one of the artemisinin combination therapies (ACTs) recommended by National authorities in many African countries today. Effectiveness data on this combination in young children is scarce.
Methods: The effectiveness of three daily doses of artesunate plus amodiaquine combination given unsupervised (n = 32), compared with the efficacy when given under full supervision (n = 29) to children with falciparum malaria were assessed in an unrandomized study.
Results: 61 patients analysed revealed a PCR-corrected day-28 cure rate of 86 % (25 of 29 patients; CI 69-95 %) in the supervised group and 63 % (20 of 32 patients; CI 45-77 %) in the unsupervised group. The difference in outcome between both groups was statistically significant (p = 0.04). No severe adverse events were reported.
Conclusion: The effectiveness of this short course regimen in young children with falciparum malaria could be augmented by increased adherence and improved formulation.

The emergence of parasites partially resistant to artemisinins (ART-R) poses a significant threat to recent gains in malaria control. ART-R has been associated with PfKelch13 (K13) mutations, which differ in fitness costs. This study investigates the gametocyte production and transmission fitness of African and Asian isolates with different K13 genotypes across multiple mosquito species.

Plasmodium malariae is the third most prevalent human malaria parasite species and contributes significantly to morbidity. Nevertheless, our comprehension of this parasite's biology remains limited, primarily due to its frequent co-infections with other species and the lack of a continuous in vitro culture system. To effectively combat and eliminate this overlooked parasite, it is imperative to acquire a better understanding of this species.

Malaria continues to be a major threat to public health in tropical regions, primarily affecting sub-Saharan Africa but also Asia, the Middle East, and Latin America. Malaria cases in Honduras have seen a significant decline and the country aims to eliminate the disease by 2030. This study examines the genetic diversity of and in Honduras using four molecular markers (, , , and ), and the chloroquine resistance marker in the context of the elimination phase.

Unlabelled: Hemozoin (HZ) is a waste product of hemoglobin digestion by and has been implicated in several pathological processes, including inflammation, oxidative stress, endothelial dysfunction, and immune dysregulation. Studying the effects of HZ on the human placenta is essential to understanding the impact of malaria infection during pregnancy. The present study explored the impact of HZ produced by and β-hematin, referred to here as natural HZ (nHZ) and synthetic HZ (sHZ), respectively, on human placental explants exposed .

Malaria remains a significant health threat in tropical and subtropical regions. The immune response to Plasmodium falciparum involves both humoral and cellular components, including phagocytosis by neutrophils. However, observing phagocytosis through light microscopy is uncommon.
