MEDIA RELEASE | Is malaria treatment safer than we think? New study investigates
A new international research collaboration led by Menzies is set to examine whether the risk of severe side effects from vivax malaria medication, primaquine, is lower than assumed to date.
Aims:
- To quantify the change in glucouse-6-phospate dehydrogenase (G6PD) activity over time in individuals with and without (controls) P. vivax malaria.
- To determine whether G6PD activity at enrolment or during steady state is associated with primaquine-induced haemolysis.
- To characterise determinants of the observed change in G6PD activity.
Summary:
8-aminoquinolines are essential for the treatment of vivax malaria but can cause severe side effects in individuals with low G6PD enzyme activity. Our preliminary data suggest that the activity of the G6PD enzyme increases in the course of a vivax malaria infection. This phenomenon has not been described before. This study therefore assesses the impact a symptomatic vivax malaria infection has on G6PD enzyme activity.
We will enrol 160 vivax malaria patients and 160 sex, age and site matched malaria free individuals at sites in Pakistan and Bangladesh. G6PD enzyme activity will be measured repeatedly five times over six months in all participants. We will then assess whether G6PD activity is increased during the malaria episode and how long it takes for G6PD enzyme activity levels to return to normal.
Implications for policy and practice:
If we can confirm our hypothesis more than 50% of patients currently considered ineligible for standard vivax malaria treatment could be eligible, rendering treatment much safer than has been assumed to date.
