There are about 35 clinical studies being (or have been) conducted in Sierra Leone. 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.
This is an open-label study evaluating the safety and immunogenicity of a booster dose of Ad26.ZEBOV administered to children who were previously vaccinated with Ad26.ZEBOV followed by MVA-BN-Filo 56 days later.
Ready-to-use therapeutic food (RUTF) is the standard of care for the treatment of SAM. UNICEF requires that there be no oil separation in these products necessitating the use of emulsifiers. The effect of emulsifiers on gut health and integrity in children receiving an exclusive diet of RUTF is unknown. The PIs have recently completed a randomized, triple-blind, controlled, clinical equivalency trial in Sierra Leone comparing the alternative oat RUTF (oat-RUTF) to standard RUTF on recovery rates in children with SAM. This study demonstrated higher rates of recovery among children receiving the oat-RUTF. The investigators hypothesize that this benefit may be due to the lack of emulsifier in the oat-RUTF resulting in improved intestinal health.This research project is a double-blind, randomized, controlled clinical effectiveness trial comparing a novel RUTF containing oats and no emulsifier and standard RUTF on recovery from severe acute malnutrition (SAM) and effects on intestinal health. The trial will be conducted in up to 40 PHUs in Western Rural and Pujehun Districts where supplementary feeding programs (SFP) are not currently available.
This study is to look at the types of sugar and protein composition in the treatment of moderate acute malnutrition and its effects on gut health. The study will use 4 different types of ready to use supplementary foods to see which one if any has better recovery rate along with looking into the gut health. Children will be treated using one food for up to 12 weeks. A subset of about 400 will be tested for intestinal permeability using the dual sugar test.
Sierra Leone faces the highest maternal mortality ratio in the world. Despite this extreme burden, the potential roles of obstetric critical care and high dependency units (HDUs) in this and other resource-limited settings remain scarcely explored. This study investigated epidemiology, clinical outcomes and risk factors for mortality in critically-ill parturients admitted to an obstetric HDU in a high volume, urban resource-limited maternity hospital.
In the Contagious Misinformation Trial the investigators aim to debunk prevalent misinformation about an infectious disease using two evidence-based methods of debunking. The two debunking methods are packaged in two audio dramas of 4 episodes each, which will be sent to the WhatsApp of participants who are randomised to intervention group 1 or 2. The control group will receive audio messages about a different topic. The primary outcome is the reduction in belief in two misinformation statements about the infectious diseases.
The TB-Speed Decentralisation study aims to increase childhood Tuberculosis (TB) case detection at district hospital (DH) and Primary health Care (PHC) levels using adapted and child-friendly specimen collection methods, i.e. Nasopharyngeal Aspirate (NPA) and stool samples, sensitive microbiological detection tests (Ultra) close to the point-of-care (Omni/G1(Edge)), reinforced training on clinical diagnosis, and standardized CXR quality and interpretation using digital radiography. The TB-Speed Decentralisation study will evaluate the impact of an innovative patient care level diagnostic approach deployed at DH and PHC levels, namely the DH focused and the PHC focused decentralization strategies. This is aimed at, improving case detection in 6 high TB incidence in low/moderate resource countries: Cambodia, Cameroon, Côte d'Ivoire, Mozambique, Sierra Leone, and Uganda, and compare effectiveness and cost-effectiveness of the two different decentralization approaches. The hypothesis is that, in countries with high and very high TB incidence (100-299 and ≥300 cases/100,000 population/year, respectively), a systematic approach to the screening for and diagnosis of TB in sick children presenting to the health system will increase childhood TB case detection, especially PTB, which represents the majority of the disease burden (>75% of case)(40). The study also hypothesizes that sputum collection using battery-operated suction machines and microbiological TB diagnosis using Omni/G1 (Edge) can be decentralized to PHC level, thus enabling TB diagnosis and treatment in children at PHC level.
Lack of access to pacemakers is a major challenge to the provision of cardiovascular health care in Low and Middle Income Countries (LMIC). Post-mortem pacemaker utilization could be safe, efficacious, and ethically responsible means of delivering the needed care. Reconditioned pacemakers can provide therapy for patients with symptomatic bradycardia and no means of receiving a new device. The objective of the clinical trial is to determine if pacemaker reutilization can be shown to be a safe means of delivering pacemakers to patients in LMIC without resources. Consented patients in this multi-center trial will be randomized to undergo implantation of either a reconditioned device or a new device.
Up to 1 in 5 women in Africa who deliver their baby by cesarean section get a wound infection. Surgical site infections (SSIs) are largely preventable, but they represent a considerable burden for health-care systems, particularly in low-income and middle-income countries. The prevention of these infections is complex and requires the integration of a range of preventive measures before, during, and after surgery. The aim of the proposed project is to determine the risk factors of Surgical Site Infection post-Cesarean Section in women admitted to Princess Christian Maternity Hospital (PCMH) in Freetown, Sierra Leone. Secondary aims are to determine the incidence of SSI and the predictors of a negative outcome in women with post-CS SSI.
The purpose of this study is to assess the safety and reactogenicity of a heterologous 2-dose regimen utilizing Ad26.ZEBOV (first vaccination; Dose 1) and MVA-BN-Filo (second vaccination; Dose 2) administered intramuscularly (IM) on Days 1 and 57, respectively.
Lassa fever carries a treated mortality in hospitalized patients of up to 50%. Lassa fever is often described as being characterized by vascular leak and shock in the terminal phase, but, whilst animal data supports this, there are limited data in humans. Therefore, an aim of this study therefore is to characterize cardiovascular function in patients with Lassa fever, with the ultimate goal of informing future trials of supportive or therapeutic strategies. Ribavirin is the current standard of care. However, the efficacy of ribavirin has not been established in a randomised controlled trial (RCT). There is very limited pharmacokinetic (PK) data on ribavirin in patients with Lassa fever and the optimal dose of ribavirin for an RCT is unknown. Furthermore, there are various hypothesized mechanisms of action of ribavirin, none of which have been investigated in humans with Lassa fever. Further aims of this study therefore are to characterize the PK of ribavirin in Lassa fever, and identify any associations between ribavirin PK parameters, viral load and markers of immune/inflammatory status.
