Summary

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.

Description

Study design :

Inclusion visit at 20 weeks of gestation :

  • randomization
  • start of supplementation (GOS/inulin or placebo)

Phone call at 24 weeks of gestation :

  • checking tolerance
  • checking observance

32 weeks of gestation visit :

  • replenishment of prebiotics
  • collect of AE

Day 1 : assessment of the Transepidermal Waterlos evaluated by a TEWAMETER

Delivery/per partum Visit

At M3 : The national recommendations for the dietary diversification of the child will be transmitted to the patients

At M6 : evaluation of AD prevalence by parents

At M12 : Pediatric dermatology consultation

  • clinical exam of child
  • the SCORAD
  • the POEM questionnaire
  • prevalence of AD
  • skin prick tests
  • FDQLI score
  • assessment of the Transepidermal Waterlos evaluated by a TEWAMETER
  • prevalence of food allergies
