Arthemeter-lumefantrine (ART-LUM) is an antimalaria drug manufactured as fixed combination tablets, each containing 20 mg of artemether and 120 mg of lumefantrine. ART-LUM was administrated according to body weight as six consecutive doses: The first dose at diagnosis and the second dose eight hours later, 0- 24-48 hours

Artesunate mefloquine (ASMQ) is an antimalaria drug administered as a combination of artesunate, 4 mg/kg/day, with mefloquine, 8 mg/kg/day orally once a day for 3 days or three times, at an interval of 24 hours (0 h - 24 h - 48 h).

Dihydroartemisinin piperaquine (DHA-PQ ) is an antimalaria drug administered as a combination of dihydroartemisinin, 2.5 mg per kg, with piperaquine phosphate, 20mg per kg daily for 3 days or three times, at an interval of 24 hours

Oral paracetamol is administered at of 50mg/kg body weight per day in three divided doses for fever exceeding 37.5oC.

amoxicillin is an antibiotic administered at 50mg per kg body weight per day for seven days in the event of concomitant bacterial infection, absent on day 0 but present during the follow up.

Quinine is an antimalarial recommended by the WHO and NMCP to be used as second line treatment for malaria. In this study, for cases of treatment failure with the artemisinin based combination therapies, quinine sulphate is administered as a second line or rescue drug at a dose of 25mg base per kg body weight per day in three divided doses for five days. The participant is then classified as ETF or LTF and excluded from the study.

Drug Resistant Malaria Due to Plasmodium Falciparum

Randomization codes were computer-generated by an offsite investigator and provided to a study nurse responsible for treatment allocation. All other study personnel were blinded to the treatment assignments, and patients were not informed of their treatment regimen. Participants from Group 1: AL, Group 2 : DHAP, Group3 : ASMQ were also given appointment card for days 1, 2, 3, 7, 14, 21, 28, 35 and 42 for clinical examination and blood smears. Blood was taken on filter paper on each of these visits.

Antimalaria Drugs Susceptibility Testing for an Effective Management of Infected Patients in Sub-Sahara Africa

Assessment of Antimalaria Drugs Susceptibility Testing for an Effective Management of Infected Patients in Sub-Sahara Africa

The primary endpoint was the 28-day and 42-day cure rates and was defined as proportion of patients with adequate clinical and parasitological response (ACPR) after 28 and 42 days of follow-up. Absence of parasitemia until day 28 and day 42 irrespective of axillary temperature was categorized as an adequate clinical and parasitologic response (ACPR). Secondary endpoints were early treatment failure (ETF), late clinical failure (LCF), late parasitological failure (LPF), adverse events (clinical and laboratory abnormalities), anaemia (Hematocrit < 30%), clearance rate of fever and parasitaemia, and gametocyte

The ability of the drug to restore hemoglobin level back to normal

The ability of the drug to completely eliminate plasmodium in the blood stream including participant without symptoms of fever

blood sample from patients with parasitaemia at any day of follow-up are analysed by PCR to evaluated the genetic profile of the MSP1 and MSP2

Chloroquine sulphate (Meriquine®; 250mg; 150 mg of chloroquine base; Baroda, India) will be administered at a total dose of 25 mg/kg (expressed as mg of CQ base per kg body weight, once daily during 3 consecutive days, following the schedule 10mg/kg Day 1; 10mg/kg day 2 and 5 mg/kg day 3).

Placebo pills will be standard placebo capsules filled with powder contents with no pharmaceutical activity. They will not be identical to the chloroquine tablets, so the study will not be double blind, but rather single blinded. Placebo tablets will be manufactured by the pharmaceutical department of the Hospital Clínic, in Barcelona, Spain.
