Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||N/A and Over|
Inclusion Criteria:- Pregnant women living in Chile's central regions - Offspring of women recruited in the cohort study
Exclusion Criteria:- None
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

Despite recent advances in the understanding of the pathogenesis of allergies and asthma, these diseases still have no clear preventative measures or curative treatments. Growing evidence shows that atopic dermatitis (AD), food allergy (FA), allergic rhinitis, and asthma are largely determined during the first 1000 days (time elapsed from conception to the 2nd birthday). This cohort aims to determine prenatal and perinatal conditions, as well as genetic and epigenetic factors, that participate in the early setting of immune responses, and the role of these in the later determination of the risk of allergic diseases, and asthma in the offspring. The investigators have designed a birth cohort of 250 families with recruitment in pregnancy (~14 weeks). The plan is to genotype relevant allergy/asthma-associated variants and will perform immunophenotyping and evaluation of allergy biomarkers in cord blood. At 2 years of age the investigators will assess if infants have developed allergic sensitization, AD, FA, as well as biomarkers of asthma including the asthma predictive index. The study will also evaluate how maternal conditions modify immune programming through epigenetic modifications, and will then confirm newborn epigenetic cues of allergy/asthma risk. Next, the investigators will assess composition/diversity of maternal gut, placenta, breastmilk and infant gut microbiome and their association with immunophenotype and biomarkers at birth, and clinical outcomes at age 2. Finally, another specific objective is to assess how environmental exposures (perinatal outdoor and indoor pollution, endotoxin and allergens) affect the incidence of allergic sensitization, AD, FA, and risk of asthma.
