There are about 751 clinical studies being (or have been) conducted in Kenya. 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.
Introduction: Iron deficiency anaemia remains a significant public health challenge. Localized food based approaches may offer a large opportunity to improve lives and address the widespread micronutrient deficiencies such as iron in affected households. Viable solutions where iron rich foods are not readily available may come through diversification approaches using foods such as amaranth grain reported to contain high iron content and good quality protein in conjunction with the use of in-home fortification. Objectives: To determine the efficacy of maize porridge enriched with amaranth flour on improving diet quality, iron intake and status in children 12-59 months in a semiarid area in Kenya. Study population: The study population will comprise children aged 12-59 months in Migwani, within the larger Mwingi district, Kenya. Mothers or principal caretakers will be interviewed on behalf of the children. In total, 270 children will be enrolled in the study. Study design: The study has a randomized controlled trial design conducted over a period of 4 months/16 weeks. Treatment/hypothesis: All participating children will be required to take the provided porridge equivalent to 80g of flour 5 days a week for 16 weeks. There will be 3 treatments groups as follows; (1) maize porridge enriched with amaranth grain flour at 70:30 maize/amaranth ratio, (2) maize porridge fortified with a multiple micronutrient powder (MixMe™) and (3) plain maize porridge group. Hypothesis: there will be a significant difference in hemoglobin and iron status between the three groups. Methods: Blood samples (5ml) will be collected by veni-puncture at baseline and after intervention. Hb concentration, Zinc protoporphyrin (ZnPP) and malaria infection will be assessed in the field. Analyses of serum ferritin, serum transferrin receptor and C-reactive protein (CRP) will be done at the participating laboratories. Main study parameter/Endpoints: Change in Hb concentration is the primary outcome of this study. Body iron measured by serum ferritin (SF) and serum transferrin receptor (STfR) are the secondary outcome. Iron deficiency will be defined as SF concentration <12 µg/L and tissue iron deficiency will be defined as serum transferrin receptor concentration of >8.3mg/L. Infection will be assessed by raised CRP (>10mg/L) as an indicator of acute inflammation and presence of malaria.
The purpose of this study is to evaluate the safety and tolerability of Ad26.ENVA.01 and Ad35-ENV in low-risk for HIV-uninfected healthy adults administered in heterologous and homologous prime-boost regimens at different time intervals.
AERAS-402 will be given to infants of at least 16 weeks of age who have already been vaccinated with BCG to determine if AERAS-402 will increase protection of infants to tuberculosis.
The aim of this epidemiology study is to characterize in a standardized way malaria transmission intensity at the clinical trial centers participating in study 110021 (NCT00866619).
Male circumcision (MC) reduces, by more than half, the risk of HIV-1 acquisition. WHO and UNAIDS recommend that "male circumcision should be recognized as an efficacious intervention for HIV prevention especially in countries and regions with heterosexual HIV epidemics and low male circumcision prevalence." As a result, programs have been introduced and scaled up for voluntary medical male circumcision. Kenya leads with the largest expansion of services. Early resumption of sexual intercourse after MC may have deleterious effects, including higher rates of post-operative surgical complications, and higher HIV acquisition among females in couples that resume sexual activity before certified wound healing. In the context of rapid scale-up of MC, adherence to post-operative clinic appointments allows clinicians to assess wound healing and to deliver risk reduction counseling. Abstinence from sexual intercourse before complete wound healing would reduce the rate of post-operative adverse events and minimize the risk of HIV transmission from HIV-infected men to their uninfected female partners. To the investigators knowledge, the effect of reminders delivered via text messaging to promote adherence to clinic visits and abstinence after MC has not been investigated. The investigators propose a randomized controlled trial in which men who will have undergone voluntary medical male circumcision at selected sites in Kisumu will be randomized to receive either the intervention (context-sensitive text messages after circumcision) or the control condition (usual care). This study seeks to determine (a) the effect of regular text messages sent to men after circumcision on attendance of the scheduled 7-day post-operative clinic visit versus usual care; (b) the proportion of men who resume sexual activity before 42 days post-procedure after receiving regular text messages versus usual care within the 42 days post-circumcision; and (c) to identify potential predictors of failure to attend the scheduled 7-day post-operative visit and early resumption of sexual intercourse.
Zinc deficiency is prevalent in children in developing countries. Zinc-supplementation is proven to reduce the duration and severity of childhood diarrhea in randomized controlled trials. However, despite this evidence, its efficacy to reduce diarrhea morbidity in adults remains unknown. The main objective of this study is to determine the efficacy of Zn-supplementation on diarrhea incidences in a vulnerable adult population. The study will be carried out in Kombewa division, Kisumu District and will involve 500 adults aged 18-55 years. They will be randomly assigned to receive Zn supplement (or placebo) on a daily basis over a 3 month period. Morbidity information will be collected daily for 4 months, while anthropometric measures and laboratory data will be obtained at study onset, end of supplementation and study conclusion. In addition, HIV and malaria tests will be carried out during the study as they are important confounders. The significant differences in diarrhea incidence between the Zn-group and the placebo-group will be determined using SPSS. The results are expected to provide the scientific basis and common pathway for development of an anti-diarrheal supplement for vulnerable populations such as environmental refugees, deprived and displaced persons, and troops prior to deployment.
The purpose of this study is to assess the safety and immunogenicity of the candidate malaria vaccine in HIV-infected infants and children
The Millennium Villages Project involves the coordinated and simultaneous delivery of a package of proven interventions in health, agriculture, infrastructure and education. The project works in partnership with governments in 10 African countries in areas where progress towards achieving the Millennium Development Goals has been insufficient. The Project evaluation will test the following hypotheses: 1. That after 5 years of operation, villages exposed to the MVP intervention will have a lower rate of under-5 mortality and parallel gains in MDG-related secondary outcomes when compared to similar villages not receiving the intervention. 2. That the coordinated delivery a multi-sector package of health and development interventions implemented through a broad-based local partnership is feasible in a diversity of sub-Saharan African contexts, and; 3. The intervention package can be delivered at a scalable cost of $40 per person per year in the health sector and $110 per person per year in total
Infants and children under two years are the group with the highest rates of iron deficiency anemia. Provision of sufficient dietary iron to this age group is a challenge, and in-home iron fortification of complementary foods using micronutrient powders can be an effective approach. However, WHO has recently cautioned against untargeted use of in-home micronutrient powders that contain the entire iron RDA for a child in a single dose in areas with high rates of infections from malaria and diarrheal disease. Therefore, in this study, we will investigate the effect on the infant gut microbiota of a low dose (ca. 25% of the RDA) of highly bioavailable iron, provided by a micronutrient powder added to a complementary food. The study aim is to determine if in-home fortification using an iron-containing micronutrient powder in Kenyan infants will improve iron status and/or modify the composition and metabolic activity of the gut microbiota. Active surveillance will be done weekly to monitor the health of the infants. Our study will be done in a subgroup (n=160) of a larger double-blind controlled feeding trial in which 330 infants will be randomized to receive a micronutrient powder containing either 2.5 mg iron or no iron for 1 year. In our substudy, the infants will be studied only over the first 6 months of the 1 year intervention. Blood samples, taken at baseline and after 6 months will be used to define the iron status and the anemia level of the infants. Stool samples (2 at baseline before intervention, 6 throughout the study and additional samples in case of diarrhea) will be obtained for analysis of the gut microbiota. In the entire study (n=330), we will measure changes in iron status over 1 year.
The purpose of the study is to evaluate the effectiveness of household-based distribution of evidence-based health products and to measure the health impact of these combined interventions on a population basis.
