Condition
Malaria, Plasmodium falciparum infection
Intervention
Two groups of 75 children meeting the inclusion criteria will be enrolled to the study and randomised to a treatment with either:
1. Lumifantrine and arthemeter, or
2. Dihydroartemisinin with piperaquine.
A finger-prick blood sample for parasite detection will be taken from children presenting at the outpatient clinic with symptoms indicating uncomplicated malaria. Name of the child, father and mother, age, weight and clinical symptoms including fever are recorded at a case record form. The blood sample will be used to prepare thick and thin blood smears, and to measure haemoglobin level by using Hemocue.
Blood smears will be Giemsa-stained and parasites counted against 200 White Blood Cells (WBC), with parasite negative results based on screening of 100 microscopic fields. Parasitological data are added to the patient card.
Children diagnosed with uncomplicated P. falciparum malaria and meeting all inclusion/exclusion criteria will be enrolled in the drug study after explaining the purpose and procedures of the study and obtaining informed consent from the parent(s) or guardian(s). After enrolment, in the drug study an additional finger-prick blood sample will be taken to store a sample on filter paper for molecular testing by Quantitative Nucleic Acid Sequence Based Amplification (QT-NASBA).
All children not included in the study will be referred back to the clinician with their patient cards for further diagnosis and treatment. They will be treated as any other outpatient and receive treatment as required.
