Long Term Outcome of Easophageal Atresia : Transmics Profiles in Adolescence

Study Overview
=================
Brief Summary
-----------------
Oesophageal atresia (OAEA), a malformation of the oesophagus present from birth, is characterized by the interruption of the continuity of the oesophagus, which then ends in a cul-de-sac. (Source: Fimatho) An operation is then required to restore continuity to the esophagus. Although this operation enables the vast majority of children to survive the neonatal period, health problems such as gastro-oesophageal reflux, eating difficulties, respiratory problems and growth problems persist throughout life. The aim of the project is to create a prospective cohort of adolescents aged 13/14, nested in the national AO registry. of adolescents born with esophageal atresia, including a biobank of esophageal mucosa and plasma blood samples. Once the clinical and omic data have been collected, the data will be transferred to the France Cohortes information system for analysis, in order to assess the long-term outcome of this rare disease and establish multi-omic profiles. Once the clinical data have been collected and the omics data (derived from analysis of the biobank's biological samples) have been generated, they will be analyzed by the project partners to assess the long-term outcome of OA and establish multiomic profiles. The raw data will be available on the France Cohorte platform.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| prevalence of gastroesophageal reflux disease (GERD) in children born with esophageal atresia | GERD = [pH/impedance-metry demonstrating pathological GERD and/or if lesions of peptic esophagitis are observed at an endoscopy in the year preceding the visit or if the child has a history of complicated GERD leading to anti-reflux surgery] | 13-14 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| the prevalence of GERD at 13-14 years of age | It will be determined from patient characteristics at birth, 1 year, 6 years and 13-14 years (ante-natal data, vital signs, presence of associated malformations, type of atresia, surgical procedures performed, surgical/digestive/respiratory/neuro-orthopaedic complications, type of diet and schooling). | Birth,1 year, 6 years and 13-14 years | 
| Quality of life, nutritional status and respiratory complications | Quality of life= EA-QoL and PedsQL The quality of life of patients in adolescence will be assessed by means of the following quality of life scales at the age of 13-14 years: PedsQL (13) and EA-QoL (11) by both the patient and a parent. Scale scores will be calculated in accordance with the authors' instructions. Nutritional status will be assessed by weight and height, and by calculating the weight/height z-score and BMI z-score using the World Health Organisation growth curves as a reference (14). Frequency of respiratory complications, assessed during clinical examination (hacking cough during infections, chronic cough, asthma, exertional symptoms (cough, dyspnoea), atopy, wheezing and/or stridor/corniness). | 13-14 years | 
| Omics and multi omics profiles in esophageal biopsiesfor patient having 1 biopsie | metabolites, proteins and methylation | 13-14 years | 
| Omics and multi omics profiles in esophageal biopsies for patient having more than 1 biopsie | metabolites, proteins and methylation | 13-14 years | 
| Omics and multi omics profiles in plasma |  | 13-14 years |
