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.
The purpose of this study is to pilot test the effectiveness, acceptability, and palatability of ACCS100 in a high-risk Kenyan population.
Introduction: The prevalence of low serum zinc in children under 5 in East Seme, Kisumu is 73.5% and this is likely due at least in part to low bioavailable zinc from the local cereal-based diet. Interventions that will increase zinc intake could prove useful in the effort to control zinc deficiency. A potential strategy is to increase zinc intake through enriched or fortified water. The Life Straw Family filter (LSF, Verstergaard Frandsen S.A, Switzerland) is capable of purifying water and at the same time enriching it with zinc at a variable concentration with mean delivery of approximately 1-4mg/L. Aims of the study: The primary aim of this study will be to quantify in under 5 year old children the contribution of the household LSF device to zinc intake and dietary zinc bioavailability in participating households. Secondary objectives are; 1) to assess change in serum zinc levels, growth, morbidity in the intervention group compared to control; 2) to characterize composition of the intestinal flora of children in the intervention group compared to control. Study Design and Methods: Consenting households from East Seme, Kisumu, Kenya will be randomly allocated to 2 treatment arms in an effectiveness study (90 under-five's per treatment arm). Group one will receive the LSF device with the zinc delivery system; group 2 will receive a LSF without the zinc delivery system. Zinc intake will be assessed in a subsample of the under 5 year old children enrolled in the effectiveness trial (n=100). This will be estimated by 24 hr recalls administered on 2 non-consecutive days in the dry and wet season. Selected food samples will be collected for direct analysis of zinc and phytic acid content, to supplement data from food composition tables (FCT's). The dietary assessment data will be used to estimate the distribution of zinc intakes in this age group and the EAR cut-off method will be used to estimate the proportion at risk of inadequate intakes. Data on water intake from the LSF device will be obtained by personal diaries and tally counters. The Zn concentration of the filtered water will be measured weekly. Using these data and the data from the dietary assessment, the contribution of the LSF zinc delivery to the overall dietary zinc intake will be estimated. The effectiveness study will be conducted as a 6-month double blind randomised trial with 3 assessment time points (baseline, midpoint and endpoint). Three ml (3ml) whole blood will be collected from under 5 year old children enrolled in the households for determination of serum zinc (SZn), C-reactive protein (CRP), Alpha-1- acid glycoprotein (AGP) and hemoglobin (Hb). Stool samples will be collected from a subsample at baseline, midpoint and endpoint in the intervention and control group to assess the composition of the gut microflora and gut inflammation. Anthropometrics (weight and height) will be measured at baseline, midpoint and endpoint of the study. Weekly active surveillance for incidence and severity of malaria, diarrhea and other infectious diseases will be done by questionnaire.
Background: Worldwide, injuries from trauma represent a major public health problem. The World Health Organization (WHO) has deemed this problem as one of the most important global priorities, calling 2011-2020 the 'Decade of Action for Road Safety'. Despite this, there is little empirical data in low and middle-income countries quantifying the burden of musculoskeletal injuries. Methods: INORMUS is a global, prospective, multi-center, observational cohort study. The primary objective of the study is to determine the mortality, re-operation and infection rates of musculoskeletal trauma patients within 30 days post-hospital admission. The INORMUS study seeks to enroll 40,000 patients from low-middle income countries in Africa, Asia, and Latin America.
This study evaluated the change in nasopharyngeal carriage (NPC) of Streptococcus pneumoniae (SPn), hypothesizing that it would be reduced post-vaccination with Streptococcus pneumoniae whole cell vaccine with aluminum hydroxide adjuvant (PATH-wSP) and that PATH-wSP would remain safe and well-tolerated over the course of the study.
There are many challenges to implementation of cervical cancer prevention in resource-limited countries, despite evidence based screening and treatment strategies. The investigators hypothesize that self-collected HPV specimens offered in a community health campaign setting will
Iron deficiency and anemia are health issues affecting mainly infants and women in developing countries. Iron deficiency in infancy can have long-lasting impact on cognitive and motor development of the child. Iron fortification has shown to be effective against anemia. However, in areas with a high burden of infectious diseases iron may increase the risk of unfavorable gut microbiota composition possibly influencing diarrhea prevalence. Therefore we want to assess the effects of home fortification of complementary food with two iron-containing micronutrient powders (MNPs) with and without the addition of a prebiotic (7.5 g of galactooligosaccharides as GOS-75) compared to a control on the composition of the gut microbiota of Kenyan infants. In addition, iron deficiency may iimpair adaptive immunity. Following Kenyan Minstry of Health guidelines, infants receive their first measles vaccine at 9 months. In this study we will use an MNP with a moderate iron dose of 5 mg, with 2.5 mg of Fe as NaFeEDTA and 2.5 mg of Fe as ferrous fumarate (+Fe). There will be 3 study groups MNP, MNP+Fe and MNP+Fe+GOS. The infants will be enrolled in the study at the age of 6-10 months and will consume a home-fortified maize porridge for four months. At baseline and endpoint (after 4 months of intervention), we will collect blood samples of the infants in order to assess anemia, iron status, and inflammation. In addition, we will assess the effect of iron supplementation on measles vaccine response. Fecal samples (from child and mother) will be collected at baseline, 3 weeks and at endpoint in order to evaluate the changes in gut microbiota and gut inflammation. During the intervention, in a sub-group of children who receive broad-spectrum antibiotics, we will compare how the three different interventions modify the effect of antibiotics on the infant gut microbiota. We will opportunistically select children that are enrolled in the study and who become ill, and who are prescribed antibiotics by the local health care team, according to the local standard of care in the study area. Five additional stool samples from these children will be collected (day 0 (before the first antibiotic dose), 5, 10, 20 and 40) to evaluate the changes in the gut microbiota and gut inflammation. Three years after the study end, we would like to collect a blood and stool sample from the children and examine the iron status and gut microbiome respectively.
This research represents a randomized trial of a program to improve timely postnatal care, comparing post-natal check-ups performed by community health workers delivered either by phone or in person to a control group. The study hypothesis is that when community health workers check on women three days after their delivery we will see improvements in the detection of maternal and child complications, better knowledge of complications and an increase in behaviors that are expected to lead to improved maternal and child health.
The investigators propose to study the effects of increased iron intake by home fortification of complementary foods on the gastrointestinal microbial development, inflammatory responses, and zinc (Zn) absorption. The proposed subjects are 9 month olds living in a malaria endemic area of rural Kenya who are randomized at 6 months of age to one of three fortificant groups: 1) Sprinkles™ with 12mg Iron(Fe)/day + other micronutrients, including 5mg/d Zn (test); Sprinkles™ with 0 mg/d Fe + other micronutrients, including 5mg/d Zn (control); Sprinkles™ with no micronutrients (placebo). The investigators hypothesize that the microbiome will be significantly different in the three groups and that Zn absorption and status, in addition to immune and oxidant status will be improved in the non-Fe fortified groups when compared to the Fe-fortified group.
