In a trial to test four ACTs [dihydroartemisinin-piperaquine (DP), amodiaquine-artesunate (AQ + AS), artemether-lumefantrine (AL), and CDA] in Uganda and Mozambique, malaria paediatric patients with G6PD A- (hemi and homozygotes) treated with CDA had non-significant higher odds of experiencing a haemoglobin drop ≥2 g/dl within the first four days after treatment (Van Malderen et al., 2012). Here, G6PD is linked to malaria.
