TRIAL DESCRIPTION
Public title Evaluation of an antibody detecting point-of-care test for the diagnosis of Taenia solium taeniosis and (euro)cysticercosis in Tanzania and Zambia
Official scientific title Evaluation of an antibody detecting point-of-care test for the diagnosis of Taenia solium taeniasis and (neuro)cysticercosis in communities and district hospitals of highly endemic, resource-poor areas in sub Saharan Africa, including capacity building
Brief summary describing the background and objectives of the trial Taenia solium taeniasis/cysticercosis (T/CC) is a neglected zoonotic parasitic disease complex with significant economic and public health impacts. It has been ranked first on the global scale of foodborne parasitoses by FAO/WHO (2014). Neurocysticercosis (NCC) is estimated to be responsible for 30% of cases of acquired epilepsy in endemic areas. Currently, there are no cheap, easy to apply, sensitive and specific diagnostic tools available for the detection of this parasite. The lateral flow test from CDC Atlanta that combines the diagnosis of (neuro) cysticercosis with the diagnosis of taeniasis, is a very promising candidate. This point-of-care (POC) test would be a major breakthrough, an enormous added value in early neurocysticercosis case- and tapeworm carrier detection and management, contributing not only significantly to improved health outcomes but also to reducing the risk of transmission. It will furthermore contribute to obtaining more epidemiological information on infection occurrence and transmission dynamics, facilitating burden of disease calculations and subsequent advocacy. The main objective of this study is to contribute to the implementation of a rapid, cheap and simple POC test for the detection of T. solium taeniasis and (neuro)cysticercosis in two resource-poor, highly endemic areas in sub-Saharan Africa. The proposed project will therefore field validate the POC test, which simultaneously detects T. solium taeniasis and (neuro)cysticercosis, in Tanzania and Zambia, at the community and district health facility levels. The project also aims to improve the T. solium disease recognition, diagnostic and clinical case management capacities of these countries as well as their capacity to conduct diagnostic and clinical studies.
