Introduction: The gastrointestinal tract is a major source of morbidity in adults with cystic fibrosis (CF), with a wide range of complications, some of them being specific to the underlying disease.
State of knowledge: Abnormal CFTR function, with reduced bicarbonate and other ion transport levels through the apical surface of epithelial cells, affects the intestinal tract including the pancreas and the liver. Similarly to what is observed in the respiratory tract, gastrointestinal CFTR dysfunction leads to mucus accumulation, dysmotility, small bowel bacterial overgrowth and inflammation with alteration of innate immune responses, all of which being likely to be interrelated. In developed countries, almost half of patients with CF are adults followed in multidisciplinary CF care centres by pneumologists who often have to manage gastrointestinal complications.
Conclusion: It therefore appears essential that adult gastroenterologists develop the expertise needed for managing CF gastrointestinal complications in close collaboration with multidisciplinary CF care centre teams to improve the quality of life of adults with CF.
