Filter by:Globally, malaria prevalence in 2016 was reported to have increased with 445,000 deaths, 91% of which occurred in sub-Sahara Africa with more than 75% being children. Individuals who carry the malaria parasite can either be symptomatic (showing signs and symptoms) or asymptomatic (without signs and symptoms). Asymptomatic malaria parasitaemia pose a very serious threat to malaria control efforts as they serve as reservoirs that fuel the transmission process. Therefore, interventions that target community-wide clearance of asymptomatic parasitaemia can drastically reduce malaria prevalence in the population and lead to elimination especially in endemic areas. Mass parasite clearance can deplete the parasite reservoirs and lower the transmission potential. Efforts are ongoing to scale-up interventions that work such as use of Long Lasting Insecticidal Nets (LLIN), Intermittent Preventive Treatment in children (IPTc), and test, treat and track (TTT). However, there is need for mass testing, treatment and tracking (MTTT) of the whole population to reduce the parasite load before implementing the aforementioned interventions. Though, Seasonal Malaria Chemoprophylaxis (SMC) is adopted for selected localities in Ghana, the impact of such interventions could be enhanced, if combined with MTTT at baseline to reduce the parasite load. IPT of children in Ghana has demonstrated a parasite load reduction from 25% to 1%. However, unanswered questions include - could this be scaled up? What can be the coverage? What is needed for MTTT scale -up? In a pilot in Ghana, a coverage of more than 75% was achieved in target communities and reduced asymptomatic parasitaemia by 24% from July 2017 to July 2018. It is important to generate time series data to better analyse and understand the prevalence trends as well as the bottlenecks. In designing interventions that aim at reducing the burden of malaria in children under five, for example, MTTT has largely been left out. This study explores the scale-up of interventions that work using community volunteers, hypothesising that implementing MTTT complemented by community-based management can reduce the prevalence of asymptomatic malaria parasite carriage in endemic communities. The effect of the interventions will be observed by comparing baseline data to evaluation data. This study will document the challenges and bottlenecks associated with scaling-up of MTTT to inform future efforts to scale-up the intervention.
This study aims to evaluate PK, safety, tolerability and efficacy of a new formulation of artemether-lumefantrine dispersible tablet in neonates and infants <5 kg body weight with acute uncomplicated Plasmodium falciparum malaria.
A Phase 1, open label clinical study to evaluate the safety, immunogenicity, tolerability and efficacy of Plasmodium falciparum Malaria Protein 014 (FMP014) combined with (ALF with QS-21), saponin molecule derived from the bark of Quillaja species (ALFQ)) in healthy adult volunteers at different doses and dosing schedules.
Bloodstream infections are frequent in children admitted to the hospital for severe febrile illness in sub-Saharan Africa.Ongoing blood culture surveillance at Kisantu Hospital showed non-typhoidal Salmonella (NTS) as the first cause of bloodstream infections in children. Bloodstream infections have a high case fatality (15 - 20%). Outcome of bloodstream infections is dependent on timely diagnosis and treatment. However, observations at Kisantu Hospital showed that many children arrive late and die early after admission. By interviewing caregivers of severely ill children admitted to Kisantu Hospital, the investigators aim to study their health itinerary, i.e. the sequence of all actions of health care seeking and care provision between the onset of febrile illness and the admission at the hospital. The investigators aim to assess the health itinerary according to the "three delays" model. The three delays model studies delays and practices at the level of health care seeking, of transport and of start of antibiotic treatment.10 Visits to referring health centers will provide complementary information about diagnosis, treatment and referral practices. In hospital follow-up will allow to assess the outcome according to the duration of health itinerary. The results of routine laboratory tests upon hospital admission will allow to stratify the health itinerary according to fever etiology. The results of this study will allow to understand the duration of the health itinerary, its possible association with case-fatality, and factors explaining for delays at every level. This information is expected to orient local health policy makers towards interventions shortening the duration of the health itinerary and in that case improve and monitor the referral system. In addition, the study results are expected to orient towards further research to understand health seeking behavior (i.e. focus-group discussions and community-based studies).
The purpose of this study is to assess the safety of intravenous sodium nitrite in African children who have moderately severe malaria.
This is to develop a model to test the efficacy of vaccines and/or drugs designed to block transmission of malaria to mosquitoes and to identify the targets of transmission-blocking immunity to malaria.
A phase Ib age de-escalation and dose escalation open label clinical trial of the safety, immunogenicity and ex-vivo efficacy of a candidate malaria vaccine Pfs25-IMX313/Matrix-M administered intramuscularly in healthy adults and young children in Tanzania
A Phase 1, open label clinical study to evaluate the safety, immunogenicity, tolerability and efficacy of Plasmodium falciparum Malaria Protein 013 (FMP013) combined with (ALF with QS-21), saponin molecule derived from the bark of Quillaja species (ALFQ)) in healthy adult volunteers at different doses and dosing schedules.
A simultaneous deployment of multiple first line therapies (MFT) for uncomplicated malaria using artemisisin based combination therapies as showed by theoretical models, may extend the useful therapeutic life of the current Artemisinin-based combination thérapies (ACTs) by reducing drug pressure and slowing the spread of resistance without putting life at risk. We therefore hypothesized that a simultaneous deployment of three ACTs targeting three segments of the population is feasible, acceptable and can achieve high coverage rate if potential barriers are well identified, well addressed and the key implementers are well-trained and adequately supported. To test this hypothesis, a quasi-experimental study will be conducted.
Open labelled, non randomized study to evaluate the effects of Artemisinin based Combined Therapies(ACTs) on schistosomiasis since Praziquantel (PZQ) which is presently the drug of choice for treating Schistosomiasis (STS), is ineffective on immature stages and there is known parasite resistance. ACTs when combined with PZQ, targeting different stages of the life cycle has shown some effectivity.
