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

As a fixed-dose combination of artesunate-amodiaquine developed by Sanofi-Aventis (France). It has the advantage of being a 3-day regimen usable by all age groups and potentially low cost. tablets are administered per every day at dose of 25mg/67.5mg for those between 4,5kg and 9kg for 48H

As a fixed-dose combination of dihydroartemisinin-piperaquine which is produced by Fouley (China). It is a potentially low cost 2-day regimen that has been used in children between 5-10kg as half a tablet of 40mg/320mg every day for 48H

This is the active comparator as a fixed-dose combination of artemether and lumefantrine which is produced by Novartis (Switzerland). The drug will be used as the comparator because it is the only fixed-dose combination with artemether currently available. Administered in children as tablets containing Artemether-Lumefantrine at (20mg/120mg) for body weights of 5-10kg every 12H within 48H.

Malaria

Pharmacology: Amodiaquine is effective against the erythrocytic stages of all four species of P. falciparum. Amodiaquine accumulates in the parasite's lysosomes and prevents breakdown of haemoglobin on which the parasite depends for its survival.
Artesunate is a water-soluble hemisuccinate derivative of artemisinin. Artesunate and its active metabolite dihydroartemisinin are potent blood schizonticides, active against the ring stage of the parasite.
The fixed-dose combination dihydroartemisinin-piperaquine has a cost advantage over other ACTs that brings it within reach of many, making it a potential best candidate for deployment in Africa and other poor countries. The drug is currently produced in China (Duo-cotecxin®).

Artesunate-Amodiaquine

It is a bisquinoline antimalarial drug (1,3-bis[1-(7-chloro-4 quinolyl)-4- piperazinyl]-propane) that was first synthesised in the 1960s, and used extensively in China and Indochina as prophylaxis and treatment during the next 20 years. A number of Chinese research groups documented that it was at least as effective as, and better tolerated than, chloroquine against falciparum and vivax malaria. With the development of piperaquine-resistant strains of P. falciparum and the emergence of the artemisinin derivatives, its use declined during the 1980s. However, during the next decade, piperaquine was rediscovered by Chinese scientists as one of a number of compounds suitable for combination with an artemisinin derivative.

Dihydroartemisinine-Piperaquine

CoArtem® is an oral, fixed combination of artemether- a derivative of artemisinin and lumefantrine- a novel molecule developed by the Academy of Military Medical Sciences (AMMS) in Beijing. It is the only co-formulated ACT approved by WHO and is currently available through WHO at a negotiated public sector price. Both compounds are effective as single agents. However, recrudescence is common with artemether and lumefantrine has a slow onset of action. A fixed combination tablet (20 mg artemether/120 mg lumefantrine) has therefore been developed. Fixed combination therapy improves compliance and has the advantage of carrying a lower risk of selecting drug resistant strains. No resistance to either component has been observed to date.

Artemisinin-Based Antimalarial Combinations and Clinical Response in Cameroon

Phase III Study to Study the Clinical Response to ACT Fixed Dose Combination in 42 Days in Uncomplicated Malaria in Cameroon

Patient's trial outcome will be classified according to the WHO guidelines (WHO 2003) with application as follows: Early Treatment Failure (ETF); Late Clinical Failure (LCF); Late Parasitological Failure (LPF); Adequate Clinical and Parasitological Response (ACPR) - Absence of parasitaemia on day 42 irrespective of temperature without previously meeting any of the criteria of early treatment failure or late clinical failure or late parasitological failure

Prevalence of adverse events (AEs) and serious adverse events (SAEs): proportion of patients who experience AEs or SAEs during the follow up period of 42 days.
Changes in vital Physiologic parameters (blood pressure, pulse rate): proportion of patients who have significant changes in vital signs comparing to baseline during the follow up period of 42 days.
Prevalence of abnormal laboratory tests: proportion of patients who have abnormal values of laboratory tests (ALAT, ASAT, Bilirubin, Creatinine, Glucose, Urea etc), during the follow up period of 42 days.
