Although effective tools for prevention and control of malaria exist, their delivery presents a problem. Intermittent presumptive treatment (IPT) with sulfadoxine-pyrimethamine (SP) is effective, yet >60% of women in Uganda do not get it as < 40%, attend antenatal care. Effective ways of delivering IPT with SP to pregnant women at a community level need to be developed. This study assessed whether community based resource persons like traditional birth attendants (TBAs), community reproductive health workers (CRHWs), adolescent peer mobilizers (APMs) and drug-shop owners (DSV) can distribute IPT with SP to pregnant women. Objectives: The objectives of this study were: - To assess community based approaches for delivering malaria prevention to pregnant women in Uganda; - To assess community perceptions, beliefs and practices associated with malaria treatment and prevention in pregnancy; - To assess whether community based resource persons can deliver IPT to pregnant women and reach those most at risk; - To assess the impact of IPT on anaemia and pregnancy outcome; - To estimate cost-effectiveness of the approaches and assess the acceptability and sustainability of the approaches. Methods: The study was conducted in 5 sub-counties of the Mukono district, situated on the shores of L. Victoria in Central Uganda. The district is hyper-endemic for malaria. 25 parishes with a total population of 75,000 people were used to test the new approaches. Phase 1 obtained qualitative data on community perceptions, beliefs and practices associated with malaria prevention in pregnancy. Phase 2 was an intervention study that assessed distribution of IPT to pregnant women by TBAs, CRHWs, APMs and DSVs compared with health units. Pregnant women of all parities were enrolled. Key resource persons in each parish were identified to sensitise the communities on the intervention. Data was collected regarding: timing of the first dose of SP, proportion of women who complete two doses of SP, birth weight of babies, proportion of low birth-weight babies, and proportion of adolescent pregnancies. The third phase of the study evaluated the sustainability of the approaches. Work Plan: The first phase of the study took two months. The second phase took 14-16 months. Data analysis was expected to take 12 months.
Isolated minority communities in China use traditional plant-based methods of mosquito control. This study is evaluating 4 plants used in this way by monitoring mosquitoes entering houses on nights when the plants are being used in this way. A blind, placebo controlled study design will monitor plant use and record mosquito species / numbers caught in CDC light traps indoors over 3 months.
The purpose of this study is to see if providing effective antimalarial treatment at home for parents/guardians to treat their children for malaria will lead to an improved health outcome compared to conventional healthcare.
This study will examine the safety and immune response of healthy adult volunteers to AMA1-C1, an experimental malaria vaccine developed by the NIAID. Malaria affects about 300 million to 500 million people worldwide each year, causing from 2 million to 3 million deaths. Increasing drug resistance to the malaria parasite, as well as widespread resistance of mosquitoes (the insects that transmit the parasite) to pesticides are reducing the ability to control malaria through these strategies. A vaccine that could reduce illness and death from malaria would be a valuable new resource in the fight against this disease. Early tests of AMA1-C1 in 66 people in the United States and in Mali, West Africa, found no serious side effects of the vaccine. This study will test a shorter schedule of vaccinations with AMA1-C1 than that used in the previous studies. Healthy volunteers between 18 and 50 years of age who weigh at least 110 pounds and with no travel to malaria endemic areas in the past 12 months may be eligible for this study. Candidates are screened with a medical history and physical examination, blood and urine tests, and a urine pregnancy test for women who are able to bear children. Participants are randomly assigned to receive three injections of either the experimental malaria vaccine or a placebo (a solution that does not contain the vaccine) over a 2-month period. The shots are given in an upper arm muscle, each 1 month apart. On the day of each injection, participants give a history of symptoms since the last visit, have a brief physical examination and blood test and, for women, a blood or urine pregnancy test. After the injection, participants remain in the clinic 60 minutes for observation. In addition to the injections, participants undergo the following procedures: - Record temperature and symptoms on a diary card daily for the first 7 days after each injection. - Follow-up clinic visits 1, 3, 7 and 14 days after each shot to check for side effects. Blood samples are drawn before each injection and at each return clinic visit to check the safety and immune response to the vaccine. - Have apheresis, a special procedure that separates certain components of the blood, 7 days after each injection to measure the function of germ-fighting blood cells. For this procedure, blood is drawn through a needle in an arm vein and directed into a machine that separates the different types of blood cells. The white cells are collected in a plastic ...
The purpose of the study is to see whether antimalarial drugs administered at the time of routine infant vaccinations prevents malaria and anemia in the first year of life.
The primary objective is to confirm the hypothesis that azithromycin plus chloroquine is non-inferior to atovaquone-proguanil for the treatment of symptomatic, uncomplicated malaria due to P. falciparum.
The primary objective is to confirm the hypothesis that azithromycin plus chloroquine is non-inferior to mefloquine for the treatment of symptomatic, uncomplicated malaria due to P. falciparum.
This is a double blinded study where 2 test vaccines will be evaluated to see if they protect persons who have never had malaria against malaria infection when bitten by mosquitoes.
This primary objective of this study is to assess whether the combination of Azithromycin with chloroquine is non-inferior to the combination of sulfadoxine-pyrimethamine plus chloroquine, when used to treat uncomplicated cases of malaria due to Plasmodium falciparum in adults in India.
