Filter by:This study aims to assess the degree of artemisinin resistance in adult and pediatric subjects presenting with uncomplicated falciparum malaria in Western Kenya. The study treatments will be Artemether Lumefantrine (AL) and Artesunate Mefloquine (ASMQ).
Multiple studies have shown that hydroxyurea has clinical efficacy in preventing acute painful episodes and reducing the need for blood transfusions in children with sickle cell anemia (SCA), but no study has been conducted in malaria endemic regions of sub-Saharan Africa, the areas with the most children with SCA. The primary goal of this study is to investigate the safety and efficacy of hydroxyurea for children with SCA in a malaria endemic region within sub-Saharan Africa.
BRIEF SUMMARY Canadians often visit areas with malaria where the preventative drug chloroquine no longer works. This leaves Canadians with the choice to use three different drugs to prevent malaria - atovaquone-proguanil, doxycycline, or mefloquine. There are more than 400 cases of malaria reported in Canada each year, a few which result in death. These cases mainly occur in people who do not take malaria pills as directed. Investigators have developed the Ottawa Malaria Decision Aid (OMDA), which is a bilingual (English and French) resource used to support malaria prevention decision-making. The OMDA contains plain language, fact-based information and helps individuals to reflect on their own values and beliefs so that they can make the best decision for their situation. In this randomized control study, the investigators will attempt to find out if using the OMDA before visiting a travel clinic affects decisional conflict and the way pills are taken. Consenting travellers will be assigned to standard care or standard care plus the malaria decision aid. Both groups will complete three questionnaires before and after travel to look at the impact on decisional conflict, preparation for decision-making, decisional regret and pill taking behaviour. Travelers' malaria can be prevented. It is our hope that by using different methods of presenting information, specifically by utilizing the OMDA, there will be an increase in adherence to appropriate malaria prophylaxis which will ultimately result in a decrease in malaria cases that arrive in Canada. This will translate into a decreased use of health care dollars and unnecessary deaths. The Objectives of this study are to evaluate whether the malaria decision aid can be integrated into the pre-travel consultation process and can: - improve a traveller's knowledge of malaria and prevention strategies; - improve a traveller's preparation for decision-making; - decrease decisional conflict; and - affect levels of adherence to prescribed malaria chemoprophylaxis. The hypotheses of this study are that: 1. A decision aid will improve the quality of decision-making about malaria chemoprophylaxis by decreasing decisional conflict and increasing knowledge about malaria and malaria pills. 2. Better decision quality will result in a greater level of adherence to prescribed malaria chemoprophylaxis.
The aim of the inSCALE project is to test the effect of innovative approaches to increase coverage of integrated community case management, which provides community based-care for diarrhoea, pneumonia and malaria, resulting in more children receiving timely and appropriate care for these three most common childhood illnesses
The aim of this study is to address this gap in knowledge by measuring the level of patient adherence to co-formulated amodiaquine and artesunate (AQ-AS) compared to artemether-lumefantrine (AL) under routine conditions in Sierra Leone and explore the key factors that influence adherence. This will be addressed through a mixed methods study that will provide not only a measurement of adherence ACTs and malaria test results, but will also provide contextual information in order to better understand factors that affect adherence. Data will be collected through a series of interviews with health workers and parents/caregivers and through observations of patient-provider consultations. The first stage of the study begins with semi-structured interviews and observations of patients/caretakers' consultations with health workers and will look at how health workers diagnose and treat malaria. This will be followed by short exit interviews at the health facility with caregivers to assess patient satisfaction with services, as well as to test the consistency between the data obtained through structured observations and the exit interviews. Follow-up surveys at the homes of patients will be used to measure and compare the adherence of participants to two different ACTs (AQAS and AL) formulations and potential factors that affect adherence. Additionally, data will be collected using in-depth interviews to collect supplementary information in order to discover, in more detail, factors that may affect behavioral choices and/or attitudes with regard to adherence.
The general objective of the study is to answer to the question: "Is the current dose of AL less efficacious in the severely malnourished compared to the non-severely malnourished children, and is PK in cause?" We aim to assess whether the current treatment dose is adequate for children with severe acute malnutrition, and we hope results will guide further recommendations for malaria treatment in this specific population.
A healthy volunteer study to characterise the exposure of the two study medications, following administration of OZ439 + TPGS granules with piperaquine phosphate granules (intended for children) and with piperaquine phosphate tablets (intended for adults). Ideally, to confirm the exposure demonstrated in an earlier bioavailability study.
Background: - Malaria is caused by small parasites carried by some mosquitoes. People can get malaria if an infected mosquito bites them. Malaria destroys red blood cells. Most malaria is mild, but some children develop severe malaria, which kills about 660,000 people annually. About 9 in 10 who die of malaria are Sub-Saharan African children, most under 5 years old. Scientists can save many lives if they find out how to prevent or relieve severe malaria. Objective: - To know if a common medicine called activated charcoal can reduce severe malaria symptoms. Eligibility: - Children 2 to 11 years old with mild malaria who live in Kenieroba, Mali. Design: - For the first 2 days and nights, participants will stay in the hospital. - They will have their medical history taken, and a physical exam. - Blood will be drawn from a thin tube inserted in their hand or forearm. This will be done 3 times overall. A drop of blood will be taken from a finger prick 12 times overall. - An antimalarial drug will be injected into the tube in the arm 4 times. Each time the drug is given, participants will drink a small cup of either water or activated charcoal. - For the following 3 days, participants will take an antimalarial pill. - On day 7, participants will visit the hospital. A drop of blood from a finger prick will be tested for malaria parasites.
This study is designed to characterise P. falciparum transmission intensity in subjects aged ≥6 months and <10 years by measurement of P. falciparum parasite prevalence, and to estimate the use of malaria control interventions at some centres selected for the EPI-MAL-002 and EPI-MAL-003 studies in sub-Saharan Western Africa.
P27A study is designed as a randomized phase Ia/Ib trial to evaluate the safety and immunogenicity of the blood stage candidate vaccine P27A against P. falciparum - P27A antigen and associated adjuvant (Alhydrogel or GLA-SE) - in malaria non exposed European volunteers(Switzerland; phase Ia) and malaria exposed African volunteers (Tanzania; phase Ib).
