Detailed Description
The investigators assessed the efficacy and safety of the ACT in uncomplicated falciparum malaria in different sentinel sites in Myanmar. The recruited patients were follow-up until day 28 or day-42 based on the ACTs. Day-0 samples were analysed for artemisinin molecular markers, (K13 kelch propeller, Pfmdr2, Pffd and Pfarps10).

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Kawthaung Site The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Kawthaung is one of the sentinel site and located at the Southern Myanmar. |
Drug: First line antimalarial in Myanmar (artemether-lumefrantrine, dihydroartemisinin-piperaquine, and artesunate-mefloquine)
Being a observational cohort study, one of the ACT was selected in each study site to assess the efficacy and safety.
|
Myawaddy Site The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Myawaddy is one of the sentinel site and located at the northern part of the Southern Myanmar. |

Thanbyuzayat Site The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Thanbyuzayat is one of the sentinel site and located at the northern part of the Southern Myanmar. |

Rakhine Site The efficacy and safety of the ACT in different sentinel sites will be assessed. The administrated anti-malarial were same and all will be administrated under direct observation. The dosage will be calculated by weight of the patients. Rakhine is one of the sentinel site and located at the western Myanmar. |

Outcome Measures
Primary Outcome Measures
- Proportion of adequate clinical and parasitological response (ACPR) [day 28 or day 42 after initial dose of ACT]
For artesunate-mefloquine or dihydroartemisinin-piperaquine, 42 days follow-ups and for artemether-lumefrantrine combinations, 28 days followe-ups
Secondary Outcome Measures
- Proportion of the day-3 parasite positivity after ACT by microscopy [3rd day after initial dose of ACT]
72 hr after ACT is one of the indicator for delayed clearance of parasitaemia in falciparum malaria
- Treatment failure rate [anytime within observation period (28/42 days after treatment with one of ACTs)]
Early Treatment Failure (ETF), Late Clinical Failure (LCF), Late Parasitological Failure (LPF) based on the WHO standard protocol and definitions
- Mutant rate [Day-0 samples]
Day-0 samples were used to amplify the artemisinin resistance molecular markers to know the mutant rate in each study sites
