Filter by:Malaria remains a major health problem, especially among children living in sub-Saharan Africa where more than 90% of the disease and deaths occur. Adding to this high burden among the children is the co-existence of parasitic worms in their intestines and urinary tract. The combined infection of malaria and parasitic worms in these children has additive adverse effects of anaemia, poor physical and cognitive development, and death. Existing control programmes for the parasitic worms are operating sub-optimally despite the 2012 London Declaration on Neglected Tropical Diseases (NTDs) of achieving 75% treatment coverage by 2020. On the other hand, a malaria prevention programme, called Seasonal Malaria Chemoprevention (SMC), introduced in the same year as the London Declaration on NTDs has achieved more than 75% treatment coverage and prevented 75-85% of cases of uncomplicated and severe malaria in children. The remarkable success of SMC has led to the recent WHO recommendation for its extension to other at-risk age groups and in highly seasonal malaria transmission settings outside the Sahel region. This encouraging development supports the need to explore the possibility of integrating helminth control programmes with other successful delivery platforms such as SMC. However, limited empirical evidence exists on an integrated approach that integrated the control of malaria and parasitic worms in a safe, acceptable, easy-to-deliver and effective manner. To address this knowledge gap, the investigators conducted a randomised controlled trial in the first stage of this project to establish the feasibility and safety of integrating helminth control with SMC among Senegalese children. This second stage will assess the effectiveness and cost-effectiveness of using SMC platform to deliver deworming drugs to preschool and school-aged children living in communities where the burden of malaria and parasitic worms is high in central Ghana. One thousand, two hundred children aged 1-14 years will be randomly assigned equally to two study communities where antimalarial (SMC) drugs and deworming drugs will be administered in combination to the children living in one study community, and antimalarial (SMC) drugs alone will be delivered to the children living in the second study community. The effectiveness of the combined delivery will be determined by checking whether the combined antimalarial and deworming drugs prevent anaemia in the children who receive the combined drugs compared to the children who receive antimalarial drugs only. We will also determine the cost and cost-effectiveness of this approach by estimating the incremental cost savings due to cases of moderate and severe anaemia averted by giving antimalarial and deworming drugs together to the children. The findings of this study would provide evidence to boost public health recommendations for an integrated control of malaria and parasitic worms among children living in the poorest countries of the world. The findings may also reinforce the empirical evidence that the future direction of healthcare systems in developing countries should be comprehensive health management rather than vertical management of a single disease.
The goal of this observational study is to test a new AI diagnostic tool for detection, specification and quantification of parasitic infections (Ascaris, Trichuris, hookworm and S. Mansoni) in School aged children in Ethiopia and Uganda. The main questions it aims to answer are: - Diagnostic Performance of the AI tool and compare to traditional manual microscopy - Repeatability and reproducibility of the AI tool and compare to traditional manual microscopy - Time-to-result for the AI tool - Cost efficiency for the AI tool and traditional manual microscopy to inform programmatic decisions. - Usability of the AI tool Participants will be asked to provide a stool sample for examination by the AI tool and traditional manual microscopy. Participants with a positive test result will receive the proper treatment (Deworming drug).
The goal of this clinical trial is to learn about the Sm-p80 + GLA-SE (Schistoshield®) vaccine in healthy participants who have not had schistosomiasis before. The main questions it aims to answer are: - if the vaccine is safe - if after vaccinated people start producing antibodies - if the vaccine works against schistosomiasis. Participants will receive three vaccines (or placebo) and are then exposed to 20 male Schistosoma cercariae. Afterwards they are treated with praziquantel to cure the infection. Researchers will compare the group vaccinated with Schistoshield® and placebo (fake vaccination) to see if the vaccine has worked.
In this study, it is hypothesized that helminth infections modulate immune responses against HIV-1 infection resulting into increased HIV-1 multiplication, faster progression to AIDS and increased episodes of AIDS-related opportunistic infections. Furthermore, the effect of helminth infections on progression of HIV-1 infection is dependent on helminth infection intensity, host background immunity, nutritional status, demographic factors and socio-economic status. Also, treatment of helminth infections using praziquantel and albendazole among HIV-1 infected individuals will lead to reduction in HIV-1 viral loads, improvement of CD4+ counts, CD4+/CD8+ ratio and Hb levels, improved weight gain and reduction of episodes of HIV-1 related opportunistic infections. In addition, HIV-1 infection is associated with poor anthelminthic treatment outcome as compared to non-HIV infected individuals
