New research supports co-administration of primaquine with artemisinin-based combination therapies for P. vivax malaria
8 October 2019
An individual patient data meta-analysis of 2,017 patients from 19 studies has found a high risk of recurrence following treatment of P. vivax malaria with artemether-lumefantrine (AL) and dihydroartemisinin-piperaquine (DP) unless they are co-administered with primaquine. The research supports recommendations that these artemisinin-based combination therapies (ACT) should be combined with primaquine.

Human trials of new antimalarial drugs are in the pipeline after KEMRI scientists successfully used bacteria to kill the parasite that causes the disease. Trials in Burkina Faso showed that Ivermectin, a conventional drug used for parasitic diseases including river blindness and elephantiasis, reduced transmission rates. The medication worked by making the blood of people who were repeatedly vaccinated lethal to mosquitoes. The study also found that Ivermectin can kill plasmodium falciparum, the malaria parasite carried by female mosquitoes, when administered to humans.

The attainment of Universal Health Coverage (UHC) is a policy priority at both global and national levels. The Sustainable Development Goals underscore the importance of health and wellbeing for all with three main objectives: equity in access to health services, access to quality health services, and protection from financial risk. In Kenya, although the government has installed UHC as a policy priority, it is still marred in misconstruction and often reduced to health financing. Researchers at KEMRI-Wellcome tracked Kenya’s progress towards UHC between 2003 and 2014 and set out recommendations to support policy makers in designing a body of UHC policy.

Malaria is a leading cause of death and illness around the world. Over 200 million cases are reported every year, and more than 400 000 people die. More than 90% of cases are reported in sub-Saharan Africa. Scientists have spent decades searching for an effective vaccine. Hence the recent excitement when Malawi’s government announced it had launched a pilot programme for the world’s first malaria vaccine, RTS,S (also known as Mosquirix©), produced by the pharmaceutical company, GSK. It’s the first vaccine to demonstrate significant reduction in malaria in children. The Conversation Africa’s Ina Skosana asked immunologist Faith Osier about RTS,S.

Lorenz Von Seidlein tells SciDev.Net that mass drug administration as “presumptive treatment” to clear the parasite reservoir was carried out in eight villages spread across Cambodia, Lao PDR, Myanmar and Vietnam. By the third month, the prevalence of P. falciparum had decreased by 92 % in those villages. Over the subsequent nine months, P. falciparum infections returned but stayed well below baseline levels, showing that MDA can stop transmission of falciparum malaria and reduce its prevalence in SE Asia, where resistance to artemisinin has hampered elimination efforts.
