Filter by:Food allergies account for only a small percentage of all adverse reactions to foods and their prevalence has increased over the past 10-15 years, particularly in industrialized countries: 3-6% of children under 3 years of age and 1-3% of adults. Food allergens in children are represented by milk, egg, wheat, soy, peanuts, tree nuts, fish, and shellfish. The majority of allergic processes that develop during the childhood tend to abate with age, whereas those that occur during adulthood tend to persist. Hypersensitivity refers to an excessive immunological reaction to food antigens with undesirable consequences. The first aim of our study is to evaluate the role of intestinal microbiota and their relationship with immune tolerance or allergic disorder. The second aim of our study is determining the biochemical metabolites on the host (human being) in allergic disorder, and these biochemical metabolites can be measured in fecal or urine samples by metabolomics methods. We try to seek to gain an advanced understanding of gut microbiota and biochemical metabolites associated with mucosal immune responses in the host. These findings could be useful for developing strategies to modify the gut microbiota or medical applications (e.g. healthy microbe preparations) involving beneficial microorganisms to control the development of allergic disorders.
In 2001-2002, a longitudinal study on the risk of atopic sensitization in children was conducted by the Pneumo-Allergology and Pediatrics departments of the CHU Saint-Pierre Hospital and at the Neonatology Department of the Queen Fabiola Children's University Hospital (HUDERF). The aim of the study was to study bacteria and endotoxins in airborne dust in Brussels homes in order to evaluate their impact on the development of allergic diseases in newborns. Between December 2000 and August 2002, 114 children (67 from HUDERF and 47 from CHU St-Pierre) were included in the study. These were eutrophic children without acquired pathology or known genetics. Simultaneously a microbial habitat assessment was performed based on a detailed description and on endotoxin assays in the airborne and deposited dust (mainly mattress).These data can be used to define habitats with high or low contamination.Samples for microbial analyzes (Gram positive and negative and mold) were also carried out. Preliminary results suggested: 1. A protective effect of airborne dust endotoxins on the risk of developing atopic dermatitis in children at 6 and 12 months of life, 2. An effect of endotoxins promoting the occurrence of wheezing in children after 6 months. In this current, new study, the investigators will recontact the children who were included in the 2003 study. The goal is to evaluate them clinically and allergically and associate the risk of sensitization / allergic diseases with the microbial exposure of the habitat, measured during the neonatal period. Siblings and parents who were exposed during the same period will also be evaluated.
The Huizhou mother-infant cohort was set up to investigate the effect of dietary factors and environmental exposures during pregnancy on health consequences of mothers and offsprings in Huizhou, China.
This is an open-label, two-part, single-center, first in human (FIH), single ascending dose (SAD) study to assess the effects of single doses of ASLAN004 when administered to healthy subjects. The objective of this study is to evaluate the safety, tolerability, and Pharmacokinetics (PK) of ASLAN004 in healthy subjects.
The purpose of this study is to evaluate whether early life natural exposure to fatty acid affects the AD risk.
