Antioxidant Micronutrients in Malaria

In the last decade, the prevalence of malaria has been escalating at an alarming rate, especially in Africa. An estimated 300 to 500 million cases each year cause 1.5 to 2.7 million deaths, more than 90% occur in children under 5 years of age in Africa (WHO 1995). Malaria is Africa's leading cause of under-five mortality (20%) and constitutes 10% of the continent's overall disease burden. It accounts for 40% of public health expenditure, 30-50% of inpatient admissions, and up to 50% of outpatient visits in areas with high malaria transmission. Antioxidant micronutrients have immunomodulatory role and may have suppressive activity.

About this study

The pathogenesis of plasmodial infection hinges on intracellular invasion of host erythrocyte and hepatocyte with possible generation of free radicals that may contribute to cellular membrane damage. This will make uninfected erythrocyte and hepatocyte to be more susceptible to merozoite invasion. Zinc and Selenium has immunomodulatory properties. They enhance cell-mediated immune response in malaria infection. This may help to adequately suppress schizont maturation and inhibit the release of merozoites. However, it is possible that they have a direct chemosuppressive or blood schizonticidal effect. The following research questions emanated from this hypothesis;

  • Do the micronutrients in question have direct suppressive or schizonticidal effect?
  • Can they be used as short course therapy with standard antimalarials in uncomplicated malaria?
  • Is their effect enhanced when used in combination with each other or with standard antimalarials?
  • Do they have any prophylactic benefit?
  • Can their use alter the course of established malaria infection?

Primary outcomes

  1. 7-day cure rate

    Time frame: 4 weeks

    7-day Cure rate will be defined as initial and sustained parasite and symptom clearance with no increase in asexual parasitemia 48 h after the initiation of treatment and the absence of microscopically detected asexual parasitemia within 120 h of the commencement of treatment until day 7

Secondary outcomes

  1. 28-day cure rate.

    Time frame: 4 weeks

    the number of patients with clinical and parasitological cure by day 28 divided by the total number of patients who could be evaluated (per protocol population).
