There are about 8 clinical studies being (or have been) conducted in South Sudan. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Tuberculosis (TB) diagnosis in children is challenging in low and middle-income countries where access to TB culture and X-ray is limited. More than half cases of childhood TB remain undiagnosed every year. A delay in TB diagnosis can lead to an increase in preventable morbidity and mortality. This study aims to provide evidence on the diagnostic accuracy of Xpert MTB/RIF Ultra in stools and urine for TB diagnosis in children.
This is an exploratory case control study with the aim to compare the Onchocerca volvulus virome between persons with onchocerciasis-associated epilepsy (OAE) and persons with onchocerciasis but without epilepsy. The main question we want to address is: Is there a virus contained in the O. volulus worm that may have a pathogenic role in causing OAE. In Maridi County, South Sudan, 20 persons with OAE with onchocerciasis nodules, and 20 age- and village-matched controls without OAE will be enrolled in a nodulectomy study.The adult O. volvulus worms will be extracted from the nodules and a viral metagenomic study of the worms. The O. volvulus virome of persons with and without OAE will be compared.
For the first time using a prospective design, a study confirms the results of previous retrospective studies, which found that strengthening onchocerciasis elimination efforts decreases the incidence of epilepsy, including nodding syndrome. Therefore, this study confirms the solid epidemiological link between onchocerciasis and epilepsy. This study also shows that a community-based "Slash and Clear" vector control method can effectively decrease blackfly biting rates and potentially decrease onchocerciasis transmission. Moreover, this study shows that epilepsy is a major cause of death in onchocerciasis endemic areas with high ongoing transmission.
This study will assess the cost and feasibility of two strategies of enhanced Mass Drug Administration (MDA) of Zithromax to treat trachoma in the Republic of South Sudan. The secondary objectives of this study are to measure trachoma infection outcomes during the 12-month follow-up period among children up to 9 years of age.
This study aims to explore whether SMC is an effective intervention in the context of Northen Bahr el Gazal state, South Sudan. It also aims to assess the protective efficacy of the antimalarials used in SMC in the target population and investigate levels of parasite resistance in the study counties. If successful, this trial should provide the evidence for SMC to be included in malaria programming and policy in South Sudan. A Type II hybrid effectiveness-implementation study design will be used to evaluate the effects of a clinical intervention on relevant outcomes whilst collecting information on implementation. It is designed to determine feasibility and effectiveness of an innovative intervention, as well as the protective efficacy of the antimalarial drugs used. The study consists of five components: 1) A series of cross-sectional surveys establishing confirmed malaria cases in children; 2) A prospective cohort study to determine the protective efficacy of SPAQ (if SPAQ provides 28 days of protection from infection) and whether drug concentrations and/or resistance influence the duration of protection; 3) A resistance markers study in children 3-59 months in the research county; 4) Modelling the protective effect of SPAQ in South Sudan to determine where SMC could be a suitable malaria prevention strategy in other areas of the country, and 5) A process evaluation to understand feasibility and acceptability of the SMC intervention in South Sudan.
This study aims to describe the burden of Post-Kala-Azar Dermal Leishmaniasis and visceral leishmaniasis relapse in a cohort of patients discharged after successful treatment of primary visceral leishmaniasis.
Diagnosis of tuberculosis (TB) in children is particularly challenging in low and middle-income countries (LMIC), and a high number of children remain undiagnosed and untreated. A delay in diagnosis can lead to an increase in preventable morbidity and mortality. Point-of-care ultrasound (POCUS) is a bedside, non-invasive, inexpensive imaging tool, and TB-focused POCUS has been used and validated for adults with HIV. This study aims to describe the TB-focused POCUS findings for children with presumptive TB aged between 6 months and 15 years old, and to stratify the results per HIV, nutritional status and age. This is a Médecins Sans Frontières (MSF) multicentric study which takes place in Guinea Bissau and South Sudan.
This study will characterize risk factors for poor COVID-19 outcomes (hospitalization, death) and clinical progression of hospitalized COVID-19 patients in South Sudan and Eastern Democratic Republic of the Congo.
