NCT02536560

Brief Summary

In this prospective observational cohort study the potential clinical consequences of antibiotic use in early life and perturbations in the gastrointestinal microbiota composition due to that antibiotic use are studied. It is hypothesized that altered microbiota may be an important underlying mechanism for impediments in the developing immune system. Differentiation will be made between a group of neonates who received antibiotics in the first week of life, and control infants who were not exposed to antibiotics in the neonatal period.

Outcome Measures

Primary Outcomes (1)

  • Clinical endpoints

    Differences in clinical outcomes between antibiotic treated infants and controls are investigated. Incidence of atopic dermatitis (eczema), food allergy, upper respiratory tract infections (URTI), lower respiratory tract infections (LRTI), gastrointestinal infections (GITI) and excessive crying are evaluated. Data are prospectively assessed by parental reports (calendar lists).

    Participants will be followed during their first year of life

Secondary Outcomes (3)

  • Microbiota composition

    Samples will be taken at eight time points during the participant's first year of life

  • Vaccine response

    around 1 year of age

  • Doctor's diagnosis

    Participants will be followed during their first year of life

Other Outcomes (12)

  • infant height

    Participant's height is monitored during the first year of life

  • infant weight

    Participant's weight is monitored during the first year of life

  • coughing

    the symptom is daily reported as present or not present (by the parents, on the calendar list), during the infant's first year of life

  • +9 more other outcomes

Study Arms (2)

Antibiotics

150 infants, (because of hospital protocol) treated with antibiotics because of a perinatal infection during the first week of life

Controls

The control group comprises 300 healthy newborns, born in the hospital and needing clinical observation for 24-48 hours for several reasons like maternal comorbidity, low probability of neonatal infection, blood sugar monitoring, meconium containing amniotic fluid, or delivery by caesarean section

Eligibility Criteria

Age1 Hour - 7 Days
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

Healthy newborns born in the hospital, observed for low probability of neonatal infection will be compared to newborns exposed to antibiotic therapy in early life (first 1-2 weeks) by investigating potential differences in intestinal fecal microbiota composition

You may qualify if:

  • Term-born babies (≥ 36 weeks gestational age)
  • (Short) stay on maternal ward or admission to neonatal ward because of antibiotic treatment
  • Signed informed consent by the parents

You may not qualify if:

  • Congenital illness or malformations
  • Severe perinatal infections for which transfer to the neonatal intensive care unit is needed
  • Maternal probiotic use ≤ six weeks before delivery
  • Insufficient knowledge of the Dutch language.
