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.

MORU researchers have found that severe malnutrition is associated with lower exposure to the antimalarial drug lumefantrine in children treated with artemether-lumefantrine, the most common treatment for uncomplicated falciparum malaria. The study, which is the first to specifically address this, calls urgently for further research into optimised dosing regimens for undernourished children.
Rapidly spreading multidrug-resistant parasites render frontline malaria drug ineffective in southeast Asia
23 July 2019
A rapidly evolving multi-drug resistant lineage of P. falciparum malaria parasites continues to spread in South East Asia, leading to alarmingly high treatment failure rates in Cambodia, Thailand and Vietnam for DHA-piperaquine, one of the world’s most important anti-malaria drugs.

A large clinical trial in Africa and Asia has shown that a 7 day course of high dose primaquine, a drug used to treat P. vivax malaria, is well tolerated and just as effective as the current standard 14 day regimen, according to a study published this week in The Lancet. These findings have important implications for the treatment and elimination of vivax malaria in the Asia Pacific.

New research by Makoto Saito and colleagues at SMRU found that a longer follow-up is required to assess antimalarial drug efficacy in pregnant women. This was found across all drugs assessed in low malaria transmission settings. The report’s authors have called for guidelines specifically for pregnant women and further investigation of optimal follow-up periods in high malaria transmission settings.

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.

A recent WWARN individual patient meta-analysis has gathered 18 published and unpublished studies from Africa and Asia to explore the relationships between identified Kelch 13 mutant alleles and delayed parasite clearance. The study results show one P. falciparum specific mutant and 20 pfk13 propeller region mutant alleles are strongly associated with the slow clearance phenotype, including 15 mutations that have not been confirmed before. It was reassuring that no pfk13 alleles associated with slow parasite clearance were observed in the parasites from African studies gathered between 2000-2017.

Malaria causes nearly half a million deaths worldwide every year. Ninety percent of them are in sub-Saharan Africa, where poor infrastructure limits delivery of drugs. But now there is worry that those drugs are losing effectiveness as disease strains become resistant. PBS News Hour special correspondent Fred de Sam Lazaro reports from Cambodia, where scientists are researching and tracking new outbreaks.

Progress against malaria has stalled, and the disease remains a significant threat to billions of people despite the expensive, decades-long efforts to contain it. In an encouraging development, MORU reported complete success in curing hundreds of patients in Southeast Asia with new three-drug combinations mixing fast-acting artemisinin with two longer-lasting drugs. It it hoped that triple therapy should become the standard for malaria treatment.

A systematic review analyses the results of 177 trials conducted between 1982 and 2016, including 18,436 patients who underwent electrocardiographic evaluation during malaria clinical trials. Nick White and colleagues found that serious cardiovascular side effects, which include sudden cardiac death, are very rare in the treatment of malaria with quinoline antimalarials. The work emphasises the importance of continued pharmacovigilance with the increasing use of quinoline antimalarials in mass treatment strategies such as intermittent preventative treatment and mass drug administration.

One of the world’s most widely used anti-malarial drugs is safe to use, say researchers, after a thorough review and analysis of nearly 200,000 malaria patients who’d taken the drug dihydroartemisinin-piperaquine (DHA-PPQ). There is such a low risk of sudden unexpected death from DHA-PPQ, one of the world’s most effective medicines to treat malaria, that there is no need to limit its current use.

Pailin, a small settlement nestling in tropical rainforest near Cambodia’s border with Thailand, lies at the heart of a region that has seen successive waves of resistance to malaria drugs arise in local people and then spread across the globe. As new waves of the disease threaten our health, worried scientists want to conduct a mass inoculation in a Cambodian region where new vaccines always seem to stop being effective.

Giving paracetamol (acetaminophen) to patients ill with severe malaria made them less likely to develop potentially fatal kidney failure. Each year severe malaria causes close to half a million deaths globally. Acute kidney injury occurs in 40% of adults and at least 10% of children with severe malaria, killing an estimated 40% of these adults and 12-24% of the children. The study reported for the first time that giving regular doses of paracetamol protects the kidney in adult patients with severe falciparum malaria.
