Primaquine and vivax malaria
Primaquine is a drug used to eliminate vivax malaria from the liver and prevent relapses. However, it causes anaemia in patients with G6PD deficiency. A new, slightly longer regimen with increasing doses of primaquine could allow to safely treat all patients with vivax malaria.
IDDO Associate Director
I am a statistician interested in improving the treatment of infectious diseases of global health importance. My main work focuses on severe malaria, notably improving the definition of severe malaria in areas of high malaria transmission. We have estimated that a third of children diagnosed with severe malaria in high transmission settings in fact have another cause of severe illness.
I also work on other infectious diseases: I am an investigator and study statistician for PLATCOV, a platform trial characterising in vivo antiviral effects of repurposed or novel drugs for COVID-19; I am an investigator on the CHARM project which aims to develop a new methodology for the assessment of new antiparasitic drugs for the treatment of Chagas disease.
