Filter by:Understanding the sexual conversion of the malaria parasite is essential to interrupt malaria transmission. A new tool is developed that, based on expression analysis of sexual stage biomarkers, will estimate sexual conversion rates in natural infections.
Open-label randomized controlled trial to test the effectiveness of whole blood transfusion for improving survival in children with severe malaria complicated by thrombocytopenia.
The aim of this study is to investigate if diabetes, obesity and metabolic syndrome affects disease presentation and severity of malaria in adults in a hospital setting in Cameroon.
The objectives of this study contains 3 parts: (1) a comparison of 1-step parenteral artesunate (AS) versus conventional 2-step parenteral artesunate in patients with severe malaria to assess the feasibility of administration, parasite and fever clearance times in two countries, (2) a quantification of convenience and costs of the new 1-step artesunate parenteral formulation versus the conventional formulation in a randomised study, (3) A cost analysis of 1-step parenteral artesunate using data from Part 1 & Part 2. This will assess health facility-level costs, and also health system costs to encompass all costs of a potential change from conventional to 1-step artesunate, including re-training, materials, and drug replacement. The conventional formulation of injectable artesunate requires a 2-step reconstitution and dilution of the artesunate hemisuccinate powder. A new formulation of injectable artesunate has been developed by Fosun Pharma requiring a simpler 1-step reconstitution. Bioequivalence of the new formulation to the conventional formulation. For part 1, a total number of participants of this study would be 200 participants, estimated 100 per site will be recruited. For part 2, a total number of 40 semi-structured interviews with study staff, health staff, policy makers, and stake holders; and survey/questionnaires with 150 health staff.
The purpose of this study is to identify the safe and effective dose of intravenous cipargamin in participants with moderately severe and severe malaria. The study also intends to evaluate clinical treatment success using a novel clinical endpoint for drug development in severe malaria. Severe malaria is a medical emergency and is affecting primarily young children in Africa. Injectable artesunate is the standard of care for the treatment of severe malaria and is highly efficacious. However, the spread of artemisinin-resistance in Plasmodium falciparum in Asian countries poses a threat for future treatment of patients with this life-threatening disease. To mitigate this risk, there is a need of another drug in malaria endemic countries. Cipargamin treatment results in rapid clearance of parasites including artemisinin resistant parasites.
In endemic areas, Plasmodium falciparum malaria exacts a huge public health toll, causing close to half a million deaths each year. In non-endemic industrialized areas, imported malaria may develop. In France, around 5000 imported cases occured annually, including 10-15% of severe malaria. The criteria for defining severe malaria in endemic areas are established by the World Health Organization (WHO), and have been adjusted for severe imported malaria. In France, in order to optimize management, severe imported malaria is separated into two groups: very severe malaria (VSM) and less severe malaria (LSM). Briefly VSM included coma and/or shock and/or respiratory failure and/or acidosis and/or hyperlactatemia and/or death during hospitalization. In France, severe imported malaria is treated with intravenous artesunate. Little is known about the management of imported VSM in the ICU with intravenous artesunate. In a French national multicentric retrospective frame, the main objective of the present study is to describe in detail: epidemiology, management, outcome and prognostic of very severe imported malaria treated with intravenous artesunate during the period 2011-2019. The second objective is to retrospectively compare two groups : VSM treated with intravenous artesunate in the ICU during 2011-2019 versus VSM treated with intravenous quinine in the ICU during 2000-2010.
In sub-Saharan Africa, non-typhoidal Salmonella (NTS) are a frequent cause of bloodstream infection, display high levels of antibiotic resistance and have a high case fatality rate (15%). In Kisantu hospital in the Democratic Republic of Congo (DR Congo), NTS account for 75% of bloodstream infection in children and many children are co-infected with Plasmodium falciparum (Pf) malaria. NTS bloodstream infection presents as a non-specific severe febrile illness, which challenges early diagnosis and, as a consequence, prompt and appropriate antibiotic treatment.Moreover, at the first level of care, frontline health workers have limited expertise and diagnostic skills and, as a consequence, clinical danger signs that indicate serious bacterial infections are often overlooked. Basic handheld diagnostic instruments and point-of-care tests can help to reliably detect danger signs and improve triage, referral and the start of antibiotics, but there is need for field implementation and adoption to low-resource settings. Further, it is known that some clinical signs and symptoms are frequent in NTS bloodstream infections. The integration of these clinical signs and symptoms in a clinical decision support model can facilitate the diagnosis of NTS bloodstream infections and target antibiotic treatment. The investigators aim to develop such a clinical decision support model based on data from children under five years old admitted to Kisantu district referral hospital in the Democratic republic of the Congo. While developing the model, the investigators will focus on the signs and symptoms that can differentiate NTS bloodstream infection from severe Pf malaria and on the clinical danger signs that can be assessed by handheld diagnostic instruments and point-of-care tests. The deliverable will be a clinical decision support model ready to integrate in an electronic decision support system.
A randomised open labeled, parallel-group, controlled trial to assess the efficacy of paracetamol to reduce kidney dysfunction caused by cell-free haemoglobin-mediated oxidative damage in paediatric patients with falciparum malaria complicated by intravascular haemolysis.
A prospective cohort study, with 171 children admitted for severe malaria that will be included in the cohort. The study will take place in Kinshasa, Democratic Republic of Congo. The primary objective is to evaluate the prevalence of five pre-specified pulmonary diagnoses that can be facilitated by the use of LUS (normal lung or acidotic breathing, ARDS, concomitant pneumonia, hydrostatic pulmonary oedema, pleural effusion).
Currently, 16 African countries include the use of pre-referral rectal artesunate (RAS) in their treatment policies. However, guidelines for RAS use vary widely across countries and inappropriate use of RAS as a monotherapy and consequential development of resistances against artemisinin based treatments is of particular concern. In the frame of the Unitaid-funded "Community Access to Rectal Artesunate for Malaria" (CARAMAL) Project, quality-assured RAS will be rolled in selected areas of the Democratic Republic of the Congo (DRC), Nigeria and Uganda. Approximately 3,000 treatments of RAS will be dispensed by trained community health workers to children <5 years of age in each project country per year. Linked to the tracking of (severe) malaria patients in the frame of the CARAMAL project, this study will assess the frequency of artemisinin resistance markers in the study settings and tentatively assess whether the introduction of RAS could increase the selection of resistant P. falciparum strains. The study will be conducted in close collaboration with the Global Malaria Programme of the WHO. Finger-prick blood samples will be collected from children < 5 years of age with signs of severe febrile illness and a positive mRDT presenting to community-based providers and referral facilities before and after the pilot roll-out of pre-referral RAS at community level.
