Key inclusion & exclusion criteria
|
Inclusion Criteria:
- capacity to consent, or to understand the requirements of the study where parental
consent is needed
- confirmed diagnosis of CF, either by sweat test or genetic testing.
Tezacaftor/Ivacaftor is indicated only for patients homozygous for the commonest CF
mutation - p.Phe508del and so we will enrol only CF patients with this genotype
Exclusion Criteria:
- currently taking CFTR modulator drug
- Contra-indication to use of Tezacaftor/Ivacaftor
- Measurement of FEV1 <40% predicted using Global Lung Initiative criteria, according to
clinical records, as participants will be required to perform a series of 10 second
breathholds throughout MRI scanning
- Contra-indication to MRI scanning, such as embedded metal, pacemaker.
- Pregnancy
- Unable to stop medications directly prescribed to alter bowel habit, such as laxatives
or anti-diarrhoeals, on the study day
- Previous resection of any part of the gastrointestinal tract apart from appendicectomy
or cholecystectomy. Surgical relief of meconium ileus or DIOS will be permitted unless
clinical records show excision of intestine >20cm in length.
- Intestinal stoma
- Diagnosis of inflammatory bowel disease or coeliac disease confirmed by biopsy
- Gastrointestinal malignancy
- Unable to comply with dietary restrictions required for the study.
