Summary

Congenital diaphragmatic hernia (CDH) is a severe congenital malformation, related to a developmental defect of the diaphragm. The incidence of CDH is approximated at 1 in 3,000 live births. Although advances in surgery and neonatal intensive care have improved the prognosis, mortality remains high, around 30-50% related to severe lung hypoplasia and persistent pulmonary hypertension. Prenatal evaluation with observed/expected Lung over Head Ratio (o/e LHR), liver position and total lung volume measured by magnetic resonance, have been shown to correlate with neonatal mortality . However, the preponderant factor of persistent pulmonary hypertension remains difficult to predict prenatally. In patients with isolated diaphragmatic hernia (without associated malformations or karyotype abnormalities), prognosis is evaluated indirectly on pulmonary development from pulmonary volume measurements. Apart from the most caricatural cases with extremely good or very pejorative values, for a large proportion of fetuses with diaphragmatic dome hernia the prognosis remains uncertain.

The aim of the proposal is to investigate whether the analysis of the proteom of the amniotic fluid of the fetuses with CDH could give information of a prognostic character. The objective of the study is to identify, from the proteomic profile of the amniotic fluid of mothers whose fetus has CDH, prognostic markers candidates for death at 2 months of the infant. The first step is to carry out an exploratory and non-interventional study on a small sample (n = 10) of the target population. This is a preliminary step before considering, if the results are encouraging, a large-scale study from a biological collection to determine candidate proteins (new biomarkers) which relative expression levels could be used as surrogate marker of pulmonary hypoplasia.
