Summary

The investigators have established the "Evaluating the Alimentary and Respiratory Tracts in Health and disease" (EARTH) research program. It provides a structured approach to analysing gastrointestinal and respiratory microbiomes, along with diet and symptomatology, in children with a gastrointestinal and/or respiratory condition with recognised long-term morbidity (e.g. cystic fibrosis, obstructive sleep apnoea, or Hirschsprung's disease).

The EARTH program consists of a series of prospective, longitudinal, controlled, observational studies, with each individual study comparing children with a chronic gastrointestinal and/or respiratory condition to healthy controls (HC). It will be conducted in an Australian tertiary paediatric hospital (although the methodology is applicable to other settings). Children with a chronic gastrointestinal and/or respiratory condition will be compared to age and gender matched HC across a 12-month period. The following will be collected at baseline, 6 and 12 months: (i) a stool sample, (ii) an oropharyngeal swab or sputum sample, (iii) a semi-quantitative food frequency questionnaire, (iv) details of disease symptomatology, (v) health-related quality of life, and (vi) psychosocial factors. Data on the intestinal and respiratory microbiomes and diet will be compared between children with a condition and HC. Correlations between dietary intake (energy, macro- and micro-nutrients), intestinal and respiratory microbiomes within each group will be explored. Data on disease symptomatology, quality of life and psychosocial factors will also be compared between children with a condition and HC.

The investigators hypothesise that:

(i) Children with chronic gastrointestinal and/or respiratory conditions will have altered intestinal and respiratory microbiomes compared to healthy children, and (ii) Diet plays a key role in influencing the intestinal and respiratory microbiomes and this may impact on clinical outcomes, biomarkers of disease, and health-related quality of life.
