Active clinical trials for "Malaria"

This study will look at blood samples taken from 300 preterm babies and newborns admitted for inpatient care at Hopital Gabriel Toure in Bamako, Mali, and to gather information that will help the investigators verify the role of malaria in illness of very small babies. Blood samples will be taken from the mothers so that the investigators can find out if they have a malaria infection and how their body fights malaria. The investigators will also determine whether the mother and newborn baby are infected with the same malaria parasite. The information from this study may be used to improve malaria treatment in very small babies. Mothers and babies whose blood is tested will receive treatment for malaria as recommended by the National Malaria Control Program (NCMP).

Malaria is one of the major public health problems in Sub-Saharan Africa. In response to this threat, Roll Back Malaria (RBM) has rolled back a strategy using ACT as first line therapy for malaria episode, a wide distribution of Insecticide Treated Bednet (ITN), intermittent presumptive treatment of pregnant women and indoor residual spraying. Recent epidemiological observations suggested a decline in malaria prevalence in some countries but further evidences are still needed to confirm this evolution. The RBM strategy requires the use of reliable rapid diagnostic test (RDT) for which an operational assessment is necessary. Lastly, home-based management of malaria is also an important compound of this strategy. However, a better understanding of the actual use of antimalarial drugs, of the use of bednet and of the barrier to the use of health care is important to implement good quality strategies for malaria control. This study is a cross-sectional community based survey made of two rounds (one in January 2010 and the second in June 2010). The general objective is to measure the prevalence of infection with Plasmodium falciparum at two periods of the year (at the moment of lowest and highest transmission based on the seasonal rainfalls) and to compare it with the prevalence estimated in 2004 after the rainy season for the same area. Specific objective are the estimation of the prevalence by age stratum, the analysis of the geographical distribution of the infection, the description of the parasitological characteristics, the assessment of three RDT, the description and the analysis of the prevention and care seek behaviours related to malaria. The study area is the great Mbarara district located in south-west of Uganda. A three-stage cluster sampling method will be used. Spatial information will be collected with global positioning system and imported to Geographical Information System. Behaviour information will be collected through face to face interview.

This study is to measure prevalence of established and candidate molecular markers of drug resistant malaria at Komé, Doba, Republic of Chad.

A school-based, prospective, cohort study was conducted to evaluate the epidemiology of P. falciparum (Pf) infections in school-age children and determine the impact of the screen-and-treat approach on Pf infection and anemia prevalence among students in two different transmission settings. Investigators aimed to evaluate how frequently malaria rapid diagnostic tests (mRDTs) fail to detect low-parasite-density infections as well as whether low-density infections contribute to the burden and health consequences of Pf infection in school-age children and whether they contain gametocytes, the parasite stage required for transmission from humans to mosquitos.

The proposed trial design has been developed to assess the consistency and reproducibility of two consecutive direct skin feeding assays (DSFA) at 24-hour interval.

The purpose of this study is to measure the impact of maternal malaria on child growth in the two first years of life in relation to fetal growth. This study is following a birth cohort of children born to pregnant women enrolled in the study "Impact of malaria infection in pregnancy on fetal and newborn growth" (protocol OXTREC 14 08 and Mahidol 2009-003-01). In this cohort growth monitoring is conducted until 2 years of age using routine anthropometric measurements such as weight, length, arm and head circumference. A few additional tests will enhance the sensitivity of the study outcomes with minimal risk. These tests will include anthropometry, screening, nutrition questionnaire and neurodevelopmental assessment.

The MATIAS study aims to demonstrate through limited scope implementation studies how injectable artesunate may be progressively rolled out nationwide in the Democratic Republic of the Congo as the preferred treatment for severe malaria.

The routine treatment of children with antimalarials will be monitored. Children with a positive malaria film and/or a positive rapid diagnostic test (RDT) will have a capillary blood sample taken to verify the diagnosis and to monitor the pattern of resistance.

Plasmodium falciparum malaria remains a global public health threat. Leading malaria vaccine candidates confer only partial short-lived protection at best. An understanding of the mechanisms by which humans acquire malaria immunity through repeated P. falciparum infections may aid the development of a malaria vaccine. This pilor study is designed to initiate the epidemiological groundwork for a future prospective cohort study of acquired malaria immunity in Kalifabougou, Mali, a rural village of approximately 5 000 individuals who are exposed to seasonal P. falciparum transmission each year from July through December. This study will estimate the age-stratified point prevalence of P. falciparum infection before the malaria season and at the peak of the 6-month malaria season, and it will estimate the age-stratified incidence of symptomatic p. falciparum infection during the 6-month malaria season. The spatial distribution of asymptomatic P. falciparum infections and incident malaria cases within the village of Kalifabougou will be determined by merging the prevalence and incidence data with census and Global Positioning System (GPS) data....

Malaria and sexually transmitted infections (STIs) are common in pregnant women in Africa and are important preventable causes of poor birth outcomes and maternal and infant mortality. This study investigated baseline characteristics of the population including: rates of STIs including HIV, prevalence of malaria and tuberculosis (TB) and resistance to common antimalarial drugs.
