Filter by:The goal of this clinical trial is to evaluate the safety of a single intravenous dose of DON in healthy adults, adults with uncomplicated malaria, and children 6 months-14 years old with clinically defined Cerebral Malaria. The main objectives are: - Determine the pharmacokinetic (PK) profile of a single dose of DON in children with CM - Determine if administration of a single intravenous dose of DON as an adjunctive therapy in children with CM is associated with improved intracerebral blood flow dynamics on transcranial doppler (TCD) - Determine if administration of a single intravenous dose of DON as an adjunctive therapy in children with CM is associated with a reduction in brain volume score on magnetic resonance imaging (MRI) - Determine if administration of a single intravenous dose of DON as an adjunctive therapy in children with cerebral malaria is associated with changes in electroencephalogram (EEG) pattern - Exploratory: Explore the metabolic mechanisms of action of adjunctive DON in children with CM Healthy adult participants will receive: - anti-emetic ondansetron - one dose of DON Adults with uncomplicated malaria will receive: - anti-emetic ondansetron - one dose of DON - artemisinin-combination therapies per Malawi Ministry of Health guidelines Pediatric participants will receive: - one dose of DON - anti-emetic ondansetron and per Malawi Ministry of Health guidelines - enteral lumefantrine therapy, and - artesunate therapy
This study evaluates the effectiveness of two interventions in Malawian children with cerebral malaria at high risk of death. One-third of the participants will receive treatment as usual, one-third will receive treatment as usual and be placed on a mechanical ventilator, and one-third will receive treatment as usual plus intravenous hypertonic saline.
- The aim is to describe disease mechanisms of severe and cerebral malaria and identify new targets for adjunctive therapies. - Despite treatment between 10-30% of patients with severe malaria die. - Metabolic acidosis and cerebral malaria are major complications associated with mortality across all age groups. Still, their underlying pathogenesis remains incompletely understood. - Using a metabolomics approach, this study aims to characterise the spectrum of acids accumulating during acidosis, and investigate patterns of metabolic dysregulation associated with coma and seizures.
Pediatric cerebral malaria (CM) affects more than 3 million children each year killing ~20% and leaving one third of survivors with long term neurologic and psychiatric sequelae. Seizures occur commonly with CM and are associated with an increased risk of death and neuropsychiatric disabilities. In this Malawi-based, dose- escalation, safety and feasibility study of enteral levetiracetam in pediatric CM, the investigators will lay the groundwork for future efficacy studies aimed at improving seizure control and ultimately decreasing the neurologic morbidity of pediatric CM.

The impact of neurological disorders is enormous worldwide, and it is increased in poor settings, due to lack of diagnosis and treatment facilities as well as delayed management. In sub-Saharan Africa, the few observational studies conducted for the past 20 years show that neurological disorders accounted for 7 to 24% of all admissions. Central nervous system (CNS) infections were suspected in one third of all patients admitted with neurological symptoms, with a specific microbial aetiology identified in half of these. Most CNS infections may be considered as "severe and treatable diseases", e.g. human African trypanosomiasis (HAT), cerebral malaria, bacterial meningitis, CNS tuberculosis etc. If left untreated, death or serious sequels occur (mortality rates were as high as 30% in the above mentioned studies), but the outcome may be favourable with timely and appropriate management. In poor settings, such conditions should be targeted in priority in the clinical decision-making process. Unfortunately, most neuro-infections present with non-specific symptoms in their early stages, leading to important diagnostic delays. Moreover, they require advanced diagnostic technology, which is not available in most tropical rural settings: here, you have to rely on clinical judgment and first-line laboratory results, whose confirming or excluding powers are limited or unknown. Several rapid diagnostic tests (RDTs) have been recently developed for conditions like malaria or HIV, but their diagnostic contribution has not been evaluated within a multi-disease approach. Thus, this research aims at improving the early diagnosis of severe and treatable neglected and non-neglected infectious diseases which present with neurological symptoms in the province of Bandundu, Democratic Republic of Congo (DRC), by combining classic clinical predictors with a panel of simple point-of-care rapid diagnostic tests. The evaluation of existing algorithms and elaboration/validation of new guidelines will be described in a subsequent protocol.
The purpose of this study is to assess if adding inhaled Nitric Oxide to other malaria treatments can improve the outcome of cerebral malaria in children aged 2months to 12 years.
Malaria remains one of the most common life-threatening illnesses in the tropics with a dramatic toll of more than one million deaths each year. A majority of malaria cases are non-complicated and only few evolve towards severe malaria resulting from the combination of parasite-specific virulence factors and host inflammatory responses. Cerebral malaria (CM) kills more than 1 million African children each year. CM carries a fatality rate of about 20% in adults, higher in children, despite timely and adequate chemotherapy. Moreover, the more rapid clearance of parasitaemia with new antimalarial drugs is not associated with improved survival, suggesting the potential interest for adjunctive therapies in the early phase of the disease. Cerebral malaria leading to seizure and coma is associated with severe intracranial hypertension caused by brain-swelling. Recent imaging and post-mortem findings in adult cerebral malaria have confirmed the presence of diffuse cerebral oedema with thalamic and cerebellar white matter hypoattenuation, diffuse petechial hemorrhages and symmetric ischemic changes involving the thalamus and the cerebellum. However, the nature of the pathogenetic processes leading to cerebral malaria is incompletely understood but mechanisms linking cytokines with endothelial cells activation in the cerebral microvasculature have been recently stressed. The effect of new neuroprotective therapies has not yet been investigated, although the manifestations of cerebral malaria partly share features with neurological stroke or acute non-specific neurological disorders. The hormone erythropoietin (EPO) is probably one of the more enthusiastic drugs in this area. EPO is as a member of type I cytokine superfamily with multiple functions, including a prominent role for erythropoiesis and neuroprotection. Systematically administered EPO crosses the blood brain barrier via the abundant expression of EPO receptors at brain capillaries, and acts as an anti-apoptotic and cytoprotective cytokine. Moreover, EPO prevents inflammation by inhibiting pro-inflammatory cytokines including TNFα, preserves endothelial cells integrity and prevents blood-brain barrier permeability. We propose a randomized clinical trial to investigate the safety and efficacy of EPO in patients presenting cerebral malaria and hospitalized at Gabriel Toure hospital, Bamako, Mali, to reduce the incidence of premature death in hospitalized patients.
The purpose of this study is to determine whether computerised cognitive rehabilitation training improves cognition in children who have had cerebral malaria.
The purpose of this study is to see if children, who develop coma from malaria, are not making enough of a vitamin-like chemical, tetrahydrobiopterin (BH4), which is required for the brain to function normally. This information may help to identify new ways to treat malaria in the future. Study participants will include 512 children, ages 6 months to 6 years. Participants will be placed into one of 4 groups: well children; children with mild malaria; children without malaria, but with a medical problem involving the brain that requires a lumbar puncture for diagnosis (a procedure in which a needle is placed into an area surrounding the spinal cord and a sample of cerebral spinal fluid is removed); and children with a severe form of malaria affecting the brain called cerebral malaria. Study procedures will include blood samples, urine samples and lumbar puncture, only if necessary for diagnosis as part of standard practice procedures. Participants will be involved in study related procedures for up to 3 weeks.
