- W4232857360 abstract "Abstract Background Malaria is a major public health problem in Togo. Guangzhou University of Chinese medicine of China, and the Ministry of Health and Social Security of Togo launched a nationwide artemisinin compound Mass Drug Administration Project in East Mono with a population of 150,000. Before launching the project, the sensitivity test of artemisinin piperaquine tablet was conducted in Elawagnon general clinic. On this background, we evaluated the efficacy and safety of artemisinin piperaquine in the treatment of uncomplicated falciparum malaria in children under five years of age. Methods In this study, children aged 6-59 months without complications of falciparum malaria were observed, and the selected cases were treated with artemisinin piperaquine. The patients were followed up for 28 days to observe the fever clearance time, parasitemia, gametophyte, cure rate, haemoglobin and msp-2 gene polymorphism. The primary end point was the 28-day cure rate, and PCR corrected reinfection and recrudescence. This research was conducted according to standardized WHO protocol for the assessment of the efficacy of anti-malarial treatment. Results A total of 91 children participated in the study. The adequate clinical and parasitological response (ACPR) before PCR-corrected were 66 (72.52%) and 90 (98.90%) after PCR-corrected. The patient was well tolerated to artemisinin piperaquine and no serious adverse reactions were observed. The average hemoglobin level increased by 0.05g/dl per day (p< 0.0001). The gametophyte doesn’t declined at the beginning of treatment, however, 14 days later, it dropped(D21:p<0. 05; D28: p< 0. 01). In the msp-2 gene polymorphism study of 24 children with positive parasite after treatment, 1 case of msp-2 with 3D7 haplotype and FC27 haplotype was reported, indicating that it’s recrudescence, with a frequency of 4.2% (1/24); The others maybe reinfection, with a frequency of 95.8% (23/24). Conclusion Artemisinin piperaquine was effective in treating uncomplicated falciparum malaria in children under 5 years of age in Togo and well tolerated. Plasmodium falciparum in Togo remains sensitive to artemisinin piperaquine, which could be used as a trial drug in the region.
