Efficacy Of Antenatal Maternal Supplementation With GOS/Inulin Prebiotics On Atopic Dermatitis Prevalence In High-Risk One-Year-Old Children (PREGRALL)

June 11, 2021 updated by: Nantes University Hospital

A Multicenter Clinical Trial To Assess The Efficacy Of Antenatal Maternal Supplementation With GOS/Inulin Prebiotics On Atopic Dermatitis Prevalence In High-Risk One-Year-Old Children.

Allergies are increasing worldwide affecting 30-40% of the population. Among this, Atopic Dermatitis (AD) is the earliest and the most common manifestation of allergic diseases (prevalence 20%). Recent studies have shown that allergies were associated with a disruption of the gut microbial 'balance' suggesting that the use of nutritional intervention very early in life may restore an optimal pattern of microflora aiming at improving the host's health. So far, most human intervention studies have mainly focused on improving postnatal infant colonization. Our study will test the hypothesis that a maternal antenatal prebiotics (GOS/inulin) supplementation may be superior to placebo for AD prevention in high-risk children.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
