Asymptomatic Plasmodium falciparum (Pf) infections debilitate the health of affected population while representing a hidden source of parasite transmission that can compromise elimination efforts. The lack of consensus on the best strategy to deal with this asymptomatic reservoir is partly due to
1. BACKGROUND In 2002, the Philippines changed its antimalarial drug policy to the combination treatment, CQ+ Sulphadoxine-pyrimethamine (SP) as 1st-line treatment and artemether-lumefantrine as 2nd-line treatment. The Department of Health (DOH) prescribed the use of artemether-lumefantrine (AL)
The aim of this study is to provide policymakers with updated efficacy and safety data of artesunate + amodiaquine in combination with a single low dose of primaquine (0.25 mg/kg) and data on genetic markers of tolerance/resistance to artemisinin based combination therapies (ACTs), proposed as an
This study will be divided into two cohorts, by age, with separate study designs. The first cohort will include children 9 through 11 months of age. The second cohort will comprise children 15 through 23 months of age. The purpose of this detailed evaluation of safety and immunogenicity is to assess
This study is to enroll 30 patients in each type of cancer. Each patient will be vaccinated with P.vivax-infected red blood cells containing approximately 0.1-1.0 × 10^7 Plasmodium parasites and be observed for the exact infection time, parasitemia condition and infection course; principal clinical
This study is to enroll 20 patients. Each patient will be vaccinated with P. vivax-infected red blood cells containing approximately 0.3-1.0 × 10^7 Plasmodium parasites and be observed for the exact infection time, parasitemia condition and infection course; principal clinical symptoms such as
Plasmodium vivax was thought not to be a problem in Duffy blood group negative Africans. However, recent research has found that P. vivax infection occurs not only in areas where Duffy-positive and -negative people live side-by-side, but also in areas where populations are predominantly
Malaria incidence has increased two- to three-folds over the past four decades, and nearly half the world's population now lives in regions endemic for malaria: In Asia, Africa, and South America. A global annual estimate of 300-500 clinical cases of malaria and mortality in the range of 1-2 million
Seasonal malaria chemoprevention (SMC) is a new strategy recommended by World Health Organization in 2012 for areas of highly seasonal transmission such as the Sahel. Although randomized controlled trials (RCTs) have shown SMC to be highly effective, evidence and experience from routine
In our study,30 patients with stage III/IV NSCLC will be enrolled to receive vaccination with an optimal concentration and amount of blood-stage P. vivax to observe the infection time, rate and cycle; principal clinical symptoms such as fever and anemia; heart, liver and kidney function; changes in
1. OBJECTIVE- To assess the efficacy of co-administered chloroquine+primaquine (CQ+PQ) vs.CQ alone (PQ being postponed up to day 28 of CQ therapy) as a schizontocidal therapy (28-day follow-up) and as radical cure among uncomplicated P. vivax malaria (6-month follow-up). Specifically:
- To measure
Analytical plan
Sysmex will be blinded to:
- All clinical data except age and gender of the participant
- All laboratory and imaging data that is not obtained by the XN-analyzers.
The clinical study team will be blinded to:
- Data from the XN-analyzers, excepting the currently validated data that is
Dihydroartemisinin-piperaquine (DHA-PPQ) Cambodia s frontline artemisinin (ART) combination therapy (ACT) for Plasmodium falciparum malaria is failing to cure nearly half of patients in its western provinces. These treatment failures are caused by parasite strains that are resistant to both ART and
Malaria is in pre-elimination status in Mexico (Rodriguez et al., 2011; WHO, 2012) the local transmission of Plasmodium falciparum was interrupted since 2000, and transmission of P. vivax, the only causative agent in the country, is reduced to very few hot spots (Ministry of Health - Mexico,
This surveillance study is a two-arm prospective evaluation of parasitological responses to directly observed treatment with CQ (vs. placebo) for the clearing of asymptomatic parasitemia. People with asymptomatic P. falciparum parasitaemia, defined as the presence of a P. falciparum infection in the
