AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children with cystic fibrosis who eat a full diet of solid foods. Families must be willing to follow a Mediterranean style diet for 6 months.
- Age
- 3 to 18 years

- Confirmed cystic fibrosis: 2 CF-causing mutations on genetic testing, or sweat chloride greater than 60 mEq/L. Children with or without pancreatic insufficiency can join.
- Earlier treatment
- Children with pancreatic insufficiency must be on PERT. Children with pancreatic sufficiency must not be on PERT.
- Biomarker or test result
- BMI Z-score of at least -1 or above. 2 CF-causing mutations on genetic testing, or sweat chloride greater than 60 mEq/L.
Main reasons for not taking part
- Malnutrition
- Needs feeding through any type of feeding tube

- Original description
There is no study to date that has evaluated the impact or effect of a Mediterranean diet in children with CF. The goal of this study would be to help provide better guidance around questions the investigators, as CF care providers continue to receive from patients and families about how to best promote overall health in pediatric cystic fibrosis from a dietary perspective. Currently, the updated nutritional recommendations are variable and broad. Parents continue to search for more concrete guidance about how best to promote long-term health given the ever-increasing life expectancy of cystic fibrosis patients in this new area of advanced therapeutics. Given the changing landscape of the CF care in general, children are less likely to struggle with early life malnutrition, and it is becoming increasingly clear that high fat, high calorie diets are not beneficial nor are necessary for all children with CF.Read full original descriptionShow less

Given the changing landscape of the CF care in general, children are less likely to struggle with early life malnutrition, and it is becoming increasingly clear that high fat, high calorie diets are not beneficial nor are necessary for all children with CF.
