Filter by:The purpose of this study is to see if children, who develop coma from malaria, are not making enough of a vitamin-like chemical, tetrahydrobiopterin (BH4), which is required for the brain to function normally. This information may help to identify new ways to treat malaria in the future. Study participants will include 512 children, ages 6 months to 6 years. Participants will be placed into one of 4 groups: well children; children with mild malaria; children without malaria, but with a medical problem involving the brain that requires a lumbar puncture for diagnosis (a procedure in which a needle is placed into an area surrounding the spinal cord and a sample of cerebral spinal fluid is removed); and children with a severe form of malaria affecting the brain called cerebral malaria. Study procedures will include blood samples, urine samples and lumbar puncture, only if necessary for diagnosis as part of standard practice procedures. Participants will be involved in study related procedures for up to 3 weeks.
The purpose of this pilot study is to evaluate the use of (1) 'malaria prevalence', (2) 'malaria incidence' and (3) 'malaria mortality' as a measure of malaria transmission in The Gambia, while mosquito insecticides (larvicides) are used to control malaria-carrying mosquitoes. Two thousand children aged 6 months to 10 years of age will be recruited from villages in the study area. They will be monitored over 7 months for the presence of malaria parasites and signs and symptoms of the disease.
This study will attempt to find out what effect mosquito insecticides have on the transmission of malaria in The Gambia. Eight hundred healthy men and women, aged 18 to 40 years, living in selected villages east of Farafenni town in The Gambia, West Africa will be screened for parasites. About 552 of these people are expected to be free of malaria and will form the study group. These people will participate in the study for 7 months and will be checked for the malaria-causing parasite every two weeks by finger prick blood sample.
To assess the safety and reactogenicity of the FMP-1/AS02A malaria vaccine in malaria-exposed children living in western Kenya and aged 12-47 months
The purpose of this study is to find out what effect malaria in the mother has on the development of her child's immune system response to malaria and whether being exposed to malaria in the womb makes a child more likely to get malaria. The study will also assess the effect that exposure to malaria in the womb has on the child's growth and development over the first three years of life. Study participants will include 480 healthy pregnant women (greater than or equal to 15 years of age), their healthy offspring, 20 healthy people from the United States with no malaria exposure or disease and 40 adult Kenyans who have previously been exposed to malaria or have malaria with no signs of infection. Study procedures will include an ultrasound (procedure to assess the baby's growth and development in the womb), blood, urine, and stool collections. Newborns will be examined at birth, and at 6, 12, 18, 24, 30 and 36 months of age.
Phase I/II Trial of a Malaria Vaccine, FMP011/AS01B, in Adults Living in the United States of America.
Phase I/II Trial of a Malaria Vaccine, FMP011/AS01B, in Adults Living in the United States of America.
The purpose of this study is to determine the safety and efficacy of sulfadoxine-pyrimethamine (SP) versus artemether-lumefantrine (Coartem) when administered to HIV+ and HIV- patients with uncomplicated P. falciparum malaria. Patients will be randomised to one of the 2 treatment and followed up (until day 14 actively) for 45 days.
The purpose of this study is to study resistance to current malaria treatments and affordable alternatives for uncomplicated malaria. Resistance occurs in areas where these treatments are used frequently. This study may help prevent future resistance. About 150 residents in Buenaventura, Colombia will participate. They will have uncomplicated malaria and they will be followed for 28 days after treatment. Physical exams and blood draws are included in study visits.
The goal of this study is to develop a safe, well tolerated, and highly efficacious azithromycin combination treatment for uncomplicated falciparum malaria. Azithromycin is a drug that has shown potential for malaria treatment. It will be combined with other malaria drugs currently approved for treatment in Thailand. About 120 people, ages 20-65, will be enrolled in Thailand. Participants will have severe cases of malaria and they will be hospitalized 28 days for treatment.
