[A 56-year-old man with cystic fibrosis and coeliac disease].
Although it has been reported that cystic fibrosis and coeliac disease can coexist, a clear relationship between the two diseases has never been firmly established. Our case concerns a 56-year-old man with cystic fibrosis (delta F508/N1303J). Over the last two years he had been complaining about diarrhoea and meteorism. The serum level of tissue transglutaminase was elevated. Duodenoscopy showed a typical pattern for coeliac disease. This was confirmed by the biopsy. After three months on a gluten-free diet the symptoms had disappeared. In the literature there are some hypotheses to explain the coexistence of cystic fibrosis and coeliac disease. Due to pancreatic insufficiency in patients with cystic fibrosis the mucosa of the bowel may have more contact with the complete gluten protein. In addition, malnutrition might contribute to some additional mucosal damage. Both mechanisms might induce an inappropriate immune response to dietary gluten. In the literature all cystic fibrosis patients with coeliac disease were diagnosed with both diseases in childhood with a maximum latency between both diseases of 26 months. It seems unlikely that manifest coeliac disease remained undiagnosed in our patient since childhood. The long time gap between the diagnosis of cystic fibrosis and the first symptoms of the celiac disease in our patient could support the above-mentioned pathophysiological hypotheses.
