TL;DR: Monitoring selection and responding to emerging signs of drug resistance are critical tools for preserving efficacy of artemisinin combination therapies; determination of the prevalence of at least pfcrt K76T and pfmdr1 N86Y should now be routine.
Journal ArticleDOI
Towards a sterile insect technique field release of Anopheles arabiensis mosquitoes in Sudan: Irradiation, transportation, and field cage experimentation
Michelle E H Helinski,Michelle E H Helinski,M. M. Hassan,Waleed M. El-Motasim,Colin A. Malcolm,Colin A. Malcolm,Bart G. J. Knols,Badria B. El-Sayed +7 more
TL;DR: It is concluded that although conditions are challenging, there are no major obstacles associated with the small-scale irradiation and transportation of insects in the current setting and studies to test the competitiveness of irradiated males can be pursued.
Journal ArticleDOI
Increased pfmdr1 copy number and sequence polymorphisms in Plasmodium falciparum isolates from Sudanese malaria patients treated with artemether-lumefantrine
Nahla B Gadalla,Ishag Adam,Salah-Eldin G El-zaki,Sahar Bashir,Izdihar Mukhtar,Mary C. Oguike,Amal A. H. Gadalla,Fathi A Mansour,David C. Warhurst,Badria B. El-Sayed,Colin J. Sutherland +10 more
TL;DR: Molecular markers for surveillance of Plasmodium falciparum resistance to current antimalarials are sorely needed and pfmdr1 gene amplification in parasites prior to treatment occurred in three individuals who had recurrent infection during follow-up.
Journal ArticleDOI
Submicroscopic Plasmodium falciparum malaria and low birth weight in an area of unstable malaria transmission in Central Sudan.
Amal H Mohammed,Magdi M Salih,Elhassan M. Elhassan,Ahmed A Mohmmed,Salah Eldin G. Elzaki,Badria B. El-Sayed,Ishag Adam +6 more
TL;DR: In Central Sudan, pregnant women were at a higher risk of having an LBW delivery if they had submicroscopic infections rather than a histological diagnosis of placental malaria.
Journal ArticleDOI
A randomized open-label trial of artesunate- sulfadoxine-pyrimethamine with or without primaquine for elimination of sub-microscopic P. falciparum parasitaemia and gametocyte carriage in eastern Sudan.
Badria B. El-Sayed,Salah-Eldin G El-zaki,Hamza A. Babiker,Nahla B Gadalla,Tellal B Ageep,Fathi A Mansour,Omer Z. Baraka,Paul Milligan,Ahmed Babiker +8 more
TL;DR: A randomized trial to compare two drug regimens for clearance of parasitaemia in order to identify the optimum regimen for use in mass drug administration in the dry season found addition of primaquine to artemisinin combination treatment did not improve elimination of Parasitaemia and prevention of gametocyte carriage in carriers with low-density parasitaemi in thedry season.
