NCT ID: NCT05973552 Recruiting - Pregnancy Clinical Trials

Iron Absorption and Requirements in Pregnancy and Lactation

PILLAR_II
Start date: July 31, 2023
Phase:
Study type: Observational

Iron requirements increase significantly during pregnancy. Current recommendations for iron intake in pregnant and lactating women (PLW) are mainly based on factorial estimates and extrapolated from non-PLW. High-quality quantitative data on iron requirements in PLW are lacking, particularly in Sub- Saharan Africa where anaemia and infections are common. The primary objective of this study is to use the stable iron isotope technique to determine iron requirements and assess iron absorption and losses in PLW living in Kenya. In this prospective observational study, we will enrol pregnant women in the first trimester (n = 250) from a previous study cohort (n=1000) who participated in an iron absorption study at least 12 months ago and received the stable iron (Fe) isotope 57Fe. This 57Fe has now distributed and equilibrated throughout the women's body iron. Once enrolled in the present study, following Kenyan guidelines, women will receive standard prenatal care, including routine daily iron and folate supplementation. We will collect venous blood samples in each trimester and at delivery, and during the first 6 months of lactation in the mothers and infants (heel prick samples). To directly assess dietary iron absorption, in a randomly selected subset of women (n=35), oral and intravenous stable iron isotope tracers (54Fe, 58Fe) will be administered in the 2nd and 3rd trimesters.

NCT ID: NCT05960019 Recruiting - PreDiabetes Clinical Trials

Blood Glucose Control Using African Traditional Fermented Foods

ATFF
Start date: January 17, 2024
Phase: N/A
Study type: Interventional

Although African traditional fermented foods have been linked to health benefits, research pertaining to the use of uniform products in the control of blood glucose is lacking. This study is aimed at assessing the effectiveness of African traditional fermented foods at reducing blood sugar amongst adult pre-diabetic patients. This study shall comprise a multi-centre parallel (3-arm) randomized controlled trial of a fermented milk product, a fermented cereal-based product, and standard medical care. 252 pre-diabetic adults shall be recruited from 12 treatment facilities located at 4 Counties (3 clinics from each County) across Kenya. The primary outcome is change in glycated haemoglobin. Secondary outcomes shall include, change in weight (BMI), waist circumference, levels of fasting plasma glucose, C reactive protein and lipid profile. Safety as well as the acceptability and experience of fermented foods as a treatment modality for pre-diabetes will additionally be assessed amongst study participants. At each study site, data comprising clinical measurements and responses from self-report questionnaires shall be collected over a follow-up period of 12 weeks. Two focus group discussions shall additionally be held in week 13. Comparison of the mean changes between the three groups shall be carried out using Analysis of Variance (ANOVA). Pairwise comparisons shall additionally be undertaken using linear mixed regression models.

NCT ID: NCT05959616 Not yet recruiting - Shigellosis Clinical Trials

Shigella Sonnei 53G Human Infection Study in Kenyan Adults

Start date: March 1, 2024
Phase: Phase 1
Study type: Interventional

Diarrhoea caused by Shigella (shigellosis) is of major public health importance. However, there are no licensed Shigella vaccines in routine use, with several candidates still in various stages of clinical development. Shigella human infection studies (HIS) have played a key role in vaccine development. These models also allow for the evaluation of immunity and other non-immunological parameters that are important to understand resistance and/or susceptibility to disease. This is particularly useful in individuals from endemic areas with varying levels of prior exposure and immunity to Shigella. Thus, establishing a Shigella HIS would enable the testing of interventions such as vaccines in a population that would most benefit from a subsequent vaccine and has potential to accelerate vaccine development. Here, the goal is to successfully establish a Shigella sonnei human infection model in Kenyan adults. This will be achieved by conducting dose-finding and dose verification Shigella studies that safely and reproducibly induce ≥60% attack rates. In this study, investigators aim to use Shigella HIS in healthy adults to develop a model as a platform to test vaccines, to study immune responses identifying potential correlates of infection, and non-immunological factors mediating and influencing susceptibility to disease. To achieve this, the study will be carried out in two phases over a period of 12-14 months. Phase A will enroll (N=up to 40 volunteers) and Phase B will enroll an additional (N=30 volunteers). To be eligible to receive a dose of 53G, volunteers must pass the screening visit. Investigators will vary the dose of bacteria in individuals enrolled for challenge to identify the dose needed to cause ≥60% shigellosis (attack rate) (Phase A) followed by testing and demonstrate the reproducibility of the model (Phase B). Thus, the main outcomes of the study will be: (1) optimisation of bacterial dose for infection success (≥60% attack rate); and (2) safety.

NCT ID: NCT05944263 Enrolling by invitation - Youth Mental Health Clinical Trials

weRISE: Youth-led Mental Health Transformation Through Cultivating Gratitude, Kindness, and Hope

Start date: July 1, 2023
Phase: N/A
Study type: Interventional

The weRISE study's primary aim is to develop and test the effects of an arts-based train-the-trainer intervention developed to cultivate gratitude, kindness, and hope among youth in schools and informal settlements in both India and Kenya, on mental health and well-being outcomes. The core theory of change for weRISE is that through cultivating these key strengths, youth will undergo empowering mindset shifts that equip them to navigate past, present, and future life challenges, including mental ill-health. Through a cross-country, phased, cluster randomized controlled design, this study will explore the question: what impacts the weRISE intervention has on gratitude, kindness, hope compared with a standard mental health literacy intervention. The investigators will also assess the impacts of weRISE on secondary outcomes such as self-efficacy, the feasibility of the youth-led delivery model, and whether impacts differ depending on setting (schools versus informal settlements, India versus Kenya). The investigators hypothesize that the weRISE intervention will result in greater improvements in mental health and well-being outcomes for youth recipients compared with a standard mental health literacy intervention, and that there will be strong positive relationships between gratitude, kindness, hope, and the mental health and well-being outcomes. The investigators hypothesize that the effects of weRISE will be similar across settings (schools and informal settlements in India and Kenya) and that the youth-led train-the-trainer model will prove effective. Through this project, investigators will work together with leading experts and youth to develop an overall intervention model, contextualize it for India and Kenya respectively, and package a set of implementation tools for weRISE. Importantly, investigators plan to iterate on the content developed and contextualized for India and Kenya and publish a youth-targeted weRISE guide that will provide any young person anywhere with content and concrete activities. The investigators will also develop a series of academic outputs including scientific articles and conference presentations to disseminate evidence and lessons learned. Finally, the investigators will produce and disseminate a policy brief to facilitate uptake and scaling of weRISE by government officials and other decision-makers.

NCT ID: NCT05919472 Recruiting - Clinical trials for Iron Deficiency Anemia

Effects of Oral Iron Supplementation on Vaccine Response in Iron Deficient Kenyan Women

Start date: July 1, 2023
Phase: N/A
Study type: Interventional

Iron deficiency (ID) anemia (IDA) is a global public health problem, with the highest prevalence in Africa. Vaccines often underperform in low- and middle- income countries (LMIC), and undernutrition, including ID, likely plays a role. Recent studies have shown the importance of iron status in vaccine response. Intravenous iron given at time of vaccination improved response to yellow fever and COVID-19 vaccines in IDA Kenyan women. Whether oral iron treatment would have a similar beneficial effect on vaccine response is uncertain. Also, timing of oral iron treatment needs further investigation. The co-primary objectives of this study are to assess 1) whether IDA in Kenyan women impairs vaccine response, and whether oral iron treatment improves their response; 2) the timing of oral iron treatment to improve vaccine response (prior to vaccination vs at time of vaccination). We will conduct a double-blind randomized controlled trial in southern Kenya to assess the effects of iron supplementation on response to three single-shot vaccines: Johnson & Johnson COVID- 19 (JJ COVID-19), the quadrivalent meningococcal vaccine (MenACWY) and the typhoid Vi polysaccharide vaccine (Typhim Vi). Women with IDA will be recruited and randomly assigned to three study groups: group 1 (pre- treatment) will receive 100 mg oral iron as ferrous sulfate (FeSO4) daily on days 1-56; group 2 (simultaneous treatment) will receive matching placebo daily on days 1-28, and 200 mg oral iron as FeSO4 daily on days 29-56; and group 3 (control) will receive matching placebo daily on days 1-56. Women in all groups will receive the JJ COVID-19 vaccine, the MenACWY and the Typhim Vi vaccine on day 28. Cellular immune response and serology will be measured at 28 days after vaccination in all groups.

NCT ID: NCT05914363 Recruiting - Hookworm Infection Clinical Trials

Evaluating Impact of Improved Floors on Health

SABABU
Start date: April 12, 2023
Phase: N/A
Study type: Interventional

The goal of this intervention study is to learn about the impact of household flooring on health in rural Kenya, and test whether providing an improved (cement stabilised, washable) floor improves the health of children and their care providers. The main questions the study aims to answer are: - What is the effect of providing a sealed, washable floor on the prevalence of infections that cause diarrhoea, intestinal worms and sand flea infections? - To what extent does the intervention reduce contamination of floors with pathogens within the home? - What is its effect of the intervention on the wellbeing of caregivers and children? - Over the course of a year, do the new floors remain undamaged, with no cracks? - Do participants living with the new floors, and the masons that helped to install the floors, like them and feel they are practical and affordable? The study will involve a trial, where half of the recruited households will be randomly chosen to receive the new floor in addition to some support on how to care for the floor and keep it clean. The other half of households will not receive anything at first, but at the end of the research project will also receive a new floor. Before the new floors are installed, the investigators will make several assessments in all study households. These will include a survey to measure household characteristics; a stool survey, to measure how many people are infected with diarrhoea-causing microorganisms and parasitic worms; a jigger flea examination among children; wellbeing assessments among children and caregivers; and soil sampling to identify microorganisms on the floor of the household. When households receive the new floor, participants will have to move out of their house for up to 7 days during installation. Participants will also be asked to attend some group meetings to discuss ways of taking care of the floor and keeping it clean. Assessments will be repeated 12 months after the floor has been delivered, and additional interviews will be held with a small number of randomly selected participants. Throughout the 12 months following delivery of the intervention, investigators will make unannounced visits to households to check the condition of the floor. Participants will also be offered treatment for parasitic worm infections after assessments have been completed at the start and end of the project.
