    ..Fecal HBD-2 levels were not increased in children with CF, in inflamed or noninflamed states. The lack of HBD-2 induction and upregulation under inflammatory conditions may suggest a diminished intestinal innate immune response in CF. ..

    ..This dietary pattern may not be optimal for the future health of children with CF, who are now expected to survive well into adulthood. ..

    ..Nutritional inadequacies may be risks of a gluten-free diet in a paediatric population. The potential implications of these inadequacies, both short and long term, remain unclear and warrant further investigation and clarification. ..

    ..Greater understanding into the underlying mechanisms of disease is much needed. The emergence of CFTR-assist therapies may potentially play a future role in the treatment of CFTR-mutation associated pancreatitis. ..
