Distinct pattern and prevalence of Plasmodium falciparum dihydropteroate synthase gene mutations in children with sickle cell anaemia and haemoglobin AA in Benin City, Nigeria: the impact of HbAA.

Abstract excerpt

Introduction: specific mutations on the Plasmodium falciparum dihydropteroate synthase (Pfdhps) gene mediate sulphadoxine/pyrimethamine (SP) resistance and thus, pose a threat to the efficacy of SP-Intermittent Preventive Therapy (SP-IPT) in malaria chemoprevention in children, including those with sickle cell anaemia (SCA). This study determined the distinct pattern and prevalence of Pfdhps mutations in children...
