Inflammation can influence several biochemical measurements those commonly used to interpret micronutrient status in children. Our primary objective is to investigate the effects of inflammation on several biochemical measurements used to interpret micronutrient status in children. A total of 40 infants (9-18 mo of age) will participate in this study. Investigators will use PENTA vaccines as a means to induce controlled inflammation (closely mimic to natural infection). PENTA is a combination of five different vaccine antigens (Hepatitis B (HBV)/ Haemophilus influenza type b (Hib) / Tetanus-Diphtheria-whole cell Pertussis (TDwP)). The investigators will also use two different stable isotopic retinols for the assessment of total body vitamin A stores. Baseline blood samples (5 mL) will be obtained from all infants and then randomly selected 30 infants will receive PENTA vaccines, while the other 10 infants will receive no vaccines. 24 hours after vaccination a finger-prick blood sample will be obtained from the infants in the vaccinated group to measure CRP and on the same day, blood samples (5 mL) will be obtained from infants who develop inflammation (CRP> 5mg/L) in the vaccine group and also from infants in the control group. Thus estimated plasma micronutrients and vitamin A stores before and after inflammation will calculate the effects of inflammation on the interpretation of micronutrient deficiencies based on biochemical indicator assessment.
The aim of this trial is to show that infants fed these new formulas, containing a blend of 5 Human Milk Oligosaccharides (HMOs), allow for growth in line with infants fed formulas without HMOs. There will be different groups in the trial: three formula-fed groups and a breastfed group.
Multi-country, cross-sectional, observational study in diverse geographic locations all over the world.
Understand the impact of switching to a commercially available infant formula on gastrointestinal symptoms
This study investigates the effects of a new infant formula on growth, safety, and tolerance in healthy term Chinese infants. Screening starts after the informed consent is obtained. Infants who are less than or equal to 44 days of age and meeting all eligibility criteria will be enrolled into the study. The total duration of the study is around 12 months which includes 8 study visits. Infants, whose mother has the intention to fully breastfeed her infant at least until 17 weeks of age will be enrolled into the breastfeeding reference group. Infants, whose mother has the intention to fully formula feed her infant as of 44 days of age at the latest, will be randomized to receive either the investigational product or control product until infants reach the age of 17 weeks. After the age of 17 weeks, infants can switch to any feeding and continue be followed up until 12 months of age. Safety, growth and tolerance parameters will be followed and collected throughout the study.
The clinical trial will investigate the effect of different formulations of ARA + 0.4% DHA in infant formula on plasma fatty acid status in healthy 6 months old infants supplemented for 6 months. A 6-month follow on phase will provide additional efficacy (e.g. infection rates, immune markers) and safety information in these 12-18 month old infants.
The aim of this study is to establish normal values of thrombin generation assay parameters in pediatrics, according to different age groups. The standardized thrombin generation assay "Genesia™" will be used. Different age groups of healthy children will be recruited : neonates, 1-3 months, 3-6 months, 6-12 months, 1-2 years, 2-6 years, 6-12 years, and 12-15 years old. Adults values will be obtained (healthy adults > 18 years old).
Background: There is no reliable method for vitamin A (VA) assessment for infants and young children. Serum VA concentration is not an authenticate indicator of VA status, while existing deuterium- VA isotope dilution methods to determine the whole body VA status require 3 weeks and not applicable for infants and children. The investigator's research group recently developed a new simplified equation to measure VA pool size in 4-5 days, correlated with compartmental model-predicted value and estimate VA pool size in adults with high precision. In this study, we validate the method in healthy infants and infants with an inflammatory condition. Hypothesis: Whole-body VA status in infant and children can be estimated without accounting for the fractional catabolic rate in the context of an inflammatory condition Specific Objectives: In this study, the investigators propose to determine the early time point equation for assessing VA pool size in infants with or without inflammatory condition using model-based compartmental analysis from the fraction of oral dose-derived 13C10-VA and 13C4-VA in plasma over time. Methods: A total of 183 infants (9-18 mo of age) will participate in this study in the following two phases of the "Super Kid study" that ensure no more than 2 venous blood samples from each infant, even though multiple time points (at least 4 subjects / time-point) over a 28-day study period will be available for mathematical modeling. In this study, investigators will use two different stable isotopic vitamin A e.g., 13C10-retinyl acetate and 13C4-retinyl acetate. 400 μg of these isotopes, dissolved in 0.5 mL of sunflower oil, will be provided directly into the infant's mouth by using a direct replacement pipette. Mothers will be asked to breastfeed their infant after oral dosing to enhance absorption of the labeled vitamin A. Specific activity of 13C10- and 13C4- retinyl acetate in the blood samples will be measured by liquid chromatography-tandem mass spectrometry (LC/MS/MS). Dietary and morbidity questionnaires will be used. Investigators will also use PENTA vaccines as a means to induce controlled inflammation (closely mimic to natural infection). PENTA is a combination of five different vaccine antigens (Hepatitis B (HBV)/ Haemophilus influenza type b (Hib) / Tetanus-Diphtheria-whole cell Pertussis (TDwP)). This vaccination is beneficial to the infants since the World Health Organization recommends a booster vaccination dose. At the end of the study, PENTA vaccines will also be provided to the study infants in the "no-vaccine" group. (A) 115 infants will be enrolled randomly into 16 groups of them 40 infants will be in the first group, while other infants will be assigned in the other 15 groups (n=5/group). On day 0 (at 0h), all infants (n=115) will receive an oral dose of 13C10-retinyl acetate. Blood samples (5 mL) will be taken from 6h to 16th day of dosing at 9 different time-points. On day 16 (at 0h), randomly selected 50% infants (n=20) in the first group, as well as 30 infants in the other 6 groups, will receive PENTA vaccines, while the other 50% infants (n=20) in the first Group, as well as 45 infants in the other 9 groups, will receive no vaccines. 24 hours after vaccination (On day 17) a finger-prick blood sample will be obtained from the infants in the vaccinated group to measure CRP (QuikRead go, Orion, Finland). Infants who do not develop inflammation (CRP> 5mg/L) after PENTA vaccination will be excluded from the study. On day 17 (at 0h), all infants (n=115) will receive another oral dose of 13C4-retinyl acetate. Blood samples (5mL) will be collected from day 16 to day 28 at 11 different time-points for each of the vaccinated and non-vaccinated infants. This study will also assess the absorption of isotopic retinol by determining in total excreted stool up to 72 h post isotope dosing in a subsample of infants (B) 68 infants will be enrolled in this phase. Of them, 28 infants will be assigned randomly into 7 groups (n=4/group). They will receive PENTA vaccines on day -1, and the next day (day 0) they will receive an oral dose of 13C4-retinyl acetate. Blood samples (5mL) will be collected from day 1 to day 28 at 8 different time points. In a separate design, 40 infants will receive an oral dose of 13C10-retinyl acetate on day 0 and blood samples (5mL) will be collected on day 4. On day 7 they all will receive another oral dose of 13C4-retinyl acetate (400 μg, dissolved in 0.5 mL of sunflower oil). On day 10, infants will receive PENTA vaccines (n=30) or no vaccine (n=10) and 1-day after vaccination, blood samples (5 mL) will be obtained from infants who develop inflammation (CRP> 5mg/L) in the vaccine group and also from infants in the control group (day 11).
