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 shizosuppresive activity.
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 reponse 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 schizosuppressive or blood schizonticidal effect. The following research questions emanated from this hypothesis;
1. Do the micronutrients in question have direct schizosuppresive or schizonticidal effect?
2. Can they be used as short course therapy with standard antimalarials in uncomplicated malaria?
3. Is their effect enhanced when used in combination with each other or with standard antimalarials?
4. Do they have any prophylactic benefit?
5. Can their use alter the course of established malaria infection?

This study was designed to determine the efficacy of both artemether-lumefantrine and artesunate-amodiaquine (but not to compare the efficacies of the two drugs) for the treatment of uncom...
Artemisinin combination therapies (ACT) are currently recommended for malaria treatment. Artemether-lumefantrine(A-L) and Artesunate+amodiaquine (A+A) have been the most commonly adopted o...
Malaria is the most important human parasitic disease and is responsible of high morbidity and mortality in resource-poor countries. Pregnant women, who are a high-risk group, are almost a...
Primary Objective: - To demonstrate the non-inferiority, in terms of clinical and parasitological efficacy on D28 of administration of Coarsucam™ (artesunate+amodiaquine fixed-d...
- Primary Objective: to evaluate the interaction with food after a single oral dose of a fixed combination of amodiaquine (AQ) and artesunate (AS) (COARSUCAM™) in healthy male ...
Ischemic heart disease remains the leading cause of morbidity and mortality in the Western world. Artesunate is the WHO-recommended drug of choice for complicated malaria (with organ failure). The adm...
The purpose of this study was to develop a novel folate-modified host-guest complex to enhance antitumor activity of the artesunate and improve the solubility and stability by encapsulated in β-cyclo...
Human cytomegalovirus (HCMV) is a major human pathogen and is associated with severe pathology, such as life-threatening courses of infection in immunocompromised individuals and neonates. Currently, ...
Currently, the national malaria control programme (NMCP) of Sierra Leone recommends artesunate-amodiaquine (ASAQ) and artemether-lumefantrine (AL) as first- and second-line treatment for uncomplicated...
A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.
A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
A nutritional condition produced by a deficiency of VITAMIN E in the diet, characterized by posterior column and spinocerebellar tract abnormalities, areflexia, ophthalmoplegia, and disturbances of gait, proprioception, and vibration. In premature infants vitamin E deficiency is associated with hemolytic anemia, thrombocytosis, edema, intraventricular hemorrhage, and increasing risk of retrolental fibroplasia and bronchopulmonary dysplasia. An apparent inborn error of vitamin E metabolism, named familial isolated vitamin E deficiency, has recently been identified. (Cecil Textbook of Medicine, 19th ed, p1181)
