Active clinical trials for "Malaria"

This is an open label uncontrolled study to determine the efficacy of fosmidomycin and clindamycin when co-administered orally over three days in the treatment of acute uncomplicated Plasmodium falciparum malaria in children. The primary study endpoints will be the cure rate on Day 28 (PCR corrected). The secondary endpoints will be the cure rate on Day 7 and the parasite and fever clearance times.

This study is to assess the value of incorporating a malaria RDT based strategy in HMM. The primary activity of the study wil be a two armed cluster randomised trial in two study sites in Uganda, one in Ghana and one in Burkina Faso. One of the Uganda sites is highly endemic and the other meso-endemic for malaria. In one arm the children will be treated presumptively for malaria with ACT (control arm) and the other arm the children will receive ACT only when they have a positive RDT result (implementation arm). The children in the implementation arm will also receive antibiotics if they have a raised respiratory rate. The primary outcome will be the recovery rate in the intervention arm compared to that of the control arm on Day 3. In addition, an acceptability assessment of RDTs in the community will be undertaken both before and after the intervention trial and a cost-effectiveness analysis of the RDT strategy will also be completed. For a sub-sample, microscopy slides will also be taken on Day 0 to demonstrate comparable levels of endemicity in control and intervention groups. These activities will be carried out over a two year period.

Patients with non-falciparum infection will be given artemether-lumefantrine for three days and will be followed up for 28 days. Besides efficacy and safety evaluations a substudy on immunology will be performed.

In this stdy, patients aged above 6 months with symptomatic malaria presenting to health centers will be enrolled for treatment with artemether-lumefantrine for P. falciparum infection, and either artemether-lumefantrine or chloroquine for P. vivax infection. Clinical, parasitologic, and hematologic parameters will be monitored for P. falciparum and P. vivax infection over a 42-day follow-up period, which will be used to evaluate drug efficacy. Results from this research study will be used to assist Ethiopia in assessing their current national malaria drug policies.

Background: There are worrying signs from Western Cambodia that parasitological responses to artesunate containing treatment regimens for uncomplicated falciparum malaria are slower than elsewhere in the world. Delayed parasite clearance and unusually high failure rates with artesunate-mefloquine have been reported. These antimalarials are central to current treatment strategies and spread of significant resistance outside this area would be a global disaster. Radical containment measures are needed. In this context there is an urgent need to proceed quickly to investigate whether there is any evidence of resistance to artemisinin derivatives in Vietnam. Objective: The primary objective is to assess the slope of the decline in the log parasitemia-time curve in patients treated with artesunate 2mg/kg/day, artesunate 4mg/kg/day or dihydroartemisinin-piperaquine once daily, and to compare the results of this study to the pharmacokinetic results and to the recent data from patients in Cambodia and Thailand treated with equivalent therapies. Methods: The trial will be conducted in Phuoc Long Hospital, Binh Phuoc Province, Vietnam. The participants will be febrile patients (aged > 10 years) with slide confirmed uncomplicated P. falciparum infection. Patients will be treated with either artesunate 2mg/kg/day, artesunate 4mg/kg/day or dihydroartemisinin-piperaquine once daily for 3 days. Patients on artesunate therapy arms will then receive 3 days of treatment with dihydroartemisinin-piperaquine with dosages according to the national guidelines. Clinical and parasitological parameters will be monitored over a 42-day follow-up period. The pharmacokinetic characteristics of artesunate and dihydroartemisinin will be assessed by using a population pharmacokinetic modeling.

The purpose of this study was to evaluate the effectiveness of the fixed combination of artesunate+mefloquine in the treatment of uncomplicated malaria caused by Plasmodium falciparum in the municipality of Cruzeiro do Sul, Juruá Valley, Brazil, where it was being used as specific first-line drug.

Riamet® or Malarone® are both recommended as the first line treatment for uncomplicated malaria in France, according to the French consensus Conference revised in 2007 on the treatment of imported malaria. The aim of the study is to compare both tolerance and efficacy of Malarone® and Riamet® in the treatment of uncomplicated imported malaria and to determine clinical and parasitological predictive factors associated with a less effectiveness. It's a multicentric, randomised study in adults with uncomplicated malaria. Treatment will be administered for 3 days, and patients will be followed for 28 days, to evaluate the therapeutic evolution. 640 patients will be included among 15 centres.

Iron deficiency and iron deficiency anemia (IDA) are the most prevalent micronutrient deficiencies on a worldwide basis, especially in developing countries. The impact of severe IDA can have mortal consequences, since without adequate hemoglobin, the brain and body become deprived of oxygen and, if allowed to continue, death may ensue. It has been shown that iron supplementation in infants and young children can enhance child development, however, it may also result in increased rates of malaria in high burden areas. The primary objective of this study is to determine the impact of providing encapsulated iron (as a powder added to complementary foods) on the susceptibility to clinical malaria among anemic and non-anemic infants and young children (6-24 months of age) living in a high malaria burden area. The value of performing this research in Ghana is primarily that malaria and anemia remain the most important causes of death and morbidity.

A randomized, controlled clinical trial conducted in Southeastern Bangladesh using artesunate monotherapy to determine the baseline sensitivity of P. falciparum to artemisinins.

More than 1.5 million deaths of African children under 5 years of age have been due to Plasmodium falciparum malaria. When HIV and malaria are present as coinfections, they enhance each other's progression. The primary purpose of this study is to compare the malarial infection levels in HIV-infected infants and children receiving protease inhibitor (PI)- or non-nucleotide reverse transcriptase inhibitor (NNRTI)-based highly active antiretroviral therapy (HAART).
