Early Risk of Asthma in Children Exposed to In-utero Maternal Obesity

The general objectives of this study are: 1. To determine whether the increased risk of asthma in children born from a pre-pregnant obese mother can be observed at 3 years of life and whether this increased risk associated with altered plasma levels of immune mediators at birth. 2. To explore in children born from pre-pregnant obese mother whether monocyte physiology and M1-M2 polarization present an altered response and expression of asthma-related immune-modulations at birth. 3. To study in neonates born from pre-pregnant obese mother whether the in vitro expression of TNFα, IL12, IL-10 and IL-4Rα in monocytes associates with changes in the DNA methylation status in the promoter regions of those genes. The study is performed in accordance with the Helsinki Declaration, and the study protocol was accepted by Institutional Review Boards at School of Medicine of the Pontificia Universidad Católica de Chile.
